On the day Apple debuted the often-delayed white-colored iPhone 4, the company’s marketing department gave a nod to the product’s troubled history.
“Finally.” read the big headline Thursday above a picture of the white phone on the homepage of Apple. com.
The white model was supposed to ship alongside the black one at the iPhone 4’s launch（推出） last June. But design and manufacturing complications delayed the process by 10 months, catching Apple off guard, executives say.
As CNN reported last month, earlier test models of the white iPhone 4 produced unclear photos, especially when the flash（閃光燈） was used. Its whiteness confused the proximity sensor （距離傳感器） , which detects when the phone is held next to someone’s head and turns off the touch screen to save battery life.
These problems weren’t present in older iPhones that came in white because they didn’t have flash photography; the proximity sensor was unaffected because the front side of previous models was black.
“We thought we were there a year ago, or less than that, when we launched the iPhone 4, and we weren’t,” Philip Schiller, Apple’s chief marketing executive, said in an interview. “It’s not as simple as making something white. There’s a lot more that goes into both the material science of it —how it holds up over time…but also in how it all works with the sensors. “
Ticonderoga Securities analyst Brian White predicts that the white model could help drive sales of Apple’s phones. He says Apple could sell 1 million to 1. 5 million every three months until the next iPhone model is unveiled, which is expected to be this fall.
Forty-five people were lined up at Apple’s flagship New York store Thursday morning to buy white iPhones, according to a CNN Money report.

According to the US government, wind farms off the Pacific coast could produce 900 gig watts of electricity every year. Unfortunately, the water there is far too deep for even the tallest windmills(see picture)to touch bottom. An experiment under way off the coast of Norway, however, could help put them anywhere.
The project, called Hywind, is the world’s first large-scale deepwater wind turbine(渦輪發(fā)電機).Although it uses a fairly standard 152-ton,2.3-megawatt turbine, Hywind represents totally new technology. The turbine will be fixed 213 feet above the water on a floating spar(see picture),a technology Hywind’s creator, the Norwegian company StatoilHydro, has developed recently. The steel spar, which is filled with stones and goes 328 feet below the sea surface, will be tied to the ocean floor by three cable(纜索)；these will keep the spar stable and prevent the turbine from moving up and down in the waves. Hywind’s stability(穩(wěn)定性)in the cold and rough sea would prove that even the deepest corners of the ocean are suitable for wind power. If all goes according to plan, the turbine will start producing electricity six miles off the coast of southwestern Norway as early as September.
To produce electricity on a large scale, a commercial wind farm will have to use bigger turbines than Hywind does, but it’s difficult enough to balance such a large turbine so high on a floating spar in the middle of the ocean. To make that turbine heavier, the whole spar’s to design a new kind of wind turbine, one whose gearbox(變速箱) sits at sea level rather than behind the blades (see picture )
Hywind is a test run, but the benefits for perfecting floating wind-farm technology could be extremely large. Out at sea, the wind is often stronger and steadier than close to shore, where all existing offshore windmills are planted. Deep-sea farms are invisible from land, which helps overcome the windmill-as-eyesore objection. If the technology catches on, it will open up vast areas of the planet’s surface to one of the best low-carbon power sources available.

小題1:The Hywind project uses totally new technology to ensure the stability of _______.
A．the cables which tie the spar to the ocean floor
B．the spar which is floating in deep-sea water
C．the blades driven by strong and steady sea wind
D．the stones filled in the spar below the sea surface
小題2:To balance a bigger turbine high on a flatting spar, a new type of turbine is to be designed with its gearbox sitting ____________.
A．on the sea floorB．on the spar top
C．a(chǎn)t sea levelD．behind the blades
小題3:Wide applications of deepwater wind power technology can ____________.
A．solve the technical problems of deepwater windmills
B．make financial profits by producing more turbines
C．settle the arguments about environmental problems
D．explore low-carbon power resources available at sea

Statistically, air travel is by far the safest way to travel, and you can make flying even safer, just by following these simple rules. As your chances of being involved in an air accident are practically nil（不存在）, many of these tips concern what you should and shouldn't do to make your journey safer when you are airborne（升空的）.
Fly on non-stop routes
Most accidents occur during the takeoff, climb, descent and landing phases of a flight, so flying non-stop reduces your exposure to these complex procedures.
Choose larger aircraft
Although small aircraft have very good safety records, those with more than 30 passenger seats are designed to comply（遵守）with much stricter regulations and are tested more regularly to make sure they still comply. Also, in t he unlikely event of a serious accident, larger aircraft provide a better opportunity for passenger survival.
Pay attention to the pre-flight safety briefing
The information may seem repetitious（重復(fù)的）, but it's worth listening to the flight attendants. And even if you’ve flown before, it doesn’t mean you know everything about the aircraft you're on, such as the location of the closest emergency exit.
Store things safely
Never put very heavy articles in the overhead storage bins. They may fall out when someone opens the bin and cause injury. Also, the bin may not be able to hold heavier objects during turbulence（氣流）.
Keep our seat belt fastened while you are seated
Cabin crew always tell you this, but it’s important. You would be seriously injured if the plane hits unexpected turbulence. Always fasten your seat belt if you are told to. The general rule of flying is this: If you are told to do something, do it first and ask questions later.
Let the flight attendant pour your hot drinks
Flight attendants are trained to handle hot drinks like coffee or tea in a crowded aisle on a moving aircraft, so allow them to pour the drink and hand it to you. Never ask to take a coffee pot from one of them.
小題1:Whom is the passage meant for?
A．Pilots.B．Flight attendants.C．Passengers.D．Airlines.
小題2:The underlined word “those” in the second tip refers to”______” .
A．smaller planesB．passengersC．larger aircraftsD．safety records
小題3:What does the author really mean by saying “Cabin crew always tells you this, but it’s important.” In the 5th tip?
A．Many people don’t pay enough attention to fastening their seat belt.
B．All passengers are glad to accept the crew’s advice.
C．The crew are very responsible.
D．There is no need to remind people to fasten their seat belt.
小題4:Which of the following is not true according to the passage?
A．Larger planes have more safety checks and are safer.
B．Take-offs are safer on non-stop flights than landings.
C．Every aircraft is different, so the safety procedures may be different.
D．Seat belts should be worn to protect against turbulence.
小題5:The best title of the passage should be”_____”.
A．The safest way to travelB．Air safety tips
C．Non-stop routesD．How to fly a plane

If you want to stay young, sit down and have a good think. This is the research finding of a team of Japanese doctors, who say that most of out brains are not getting enough exercise, and as a result, we are growing old unnecessarily soon.
Professor Taiju Matsuzawa wanted to find out why quite healthy farmers in northern Japan appeared to be losing their ability to think and reason at a rather early age, and how the speed of getting old could be slowed down.
With a team of researchers at Tokyo National University, he set about measuring brain sizes of a thousand people of different ages with different jobs.
Computer technology helped the researchers to get most exact measurements of the sizes of the front and side parts of the brain, which have something to do with thinking and feeling, and decide the human character. As we all know, the back part of the brain, which controls task like eating and breathing, does not contract(萎縮) with age.
Contraction of front and side parts, as cells(細胞) die off, was seen in some people in their thirties, but it was still not found in some sixty and seventy-year-olds.
Matsuzawa concluded from his tests that there is a simple way to prevent the contraction---using the head.
The findings show that contraction of the brain begins sooner in people in the country than those in the towns. Those with least possibility, says Matsuzawa, are lawyers, followed by university professors and doctors. White-collar workers doing the same work day after day in government offices are, however, as possible to have contracting brains as the farm workers, bus drivers and shop assistants.
小題1: The team of doctors wanted to find out ____.
A．a(chǎn)t what point people grow live longer.
B．how to make people live longer
C．the size of certain people’s brains.
D．which group of people are the busiest
小題2:Their research findings are based on ______.c
A．a(chǎn)n examination of farmers in northern Japan
B．using computer technology
C．examining the brain sizes of different people
D．tests given a thousand old people
小題3:The doctor’s tests show that ______.
A．our brains contract as we grow older
B．one part of the brain does not contract
C．sixty-year-olds have better brains than thirty-year-olds
D．contraction of the brain begins sooner in people in the country
小題4: According to the article, _____ are growing mentally old earlier.
A．engineersB．office clerksC．professorsD．researchers
小題5:The most possible conclusion of the article is that ____.
A．most of us should take more exercise
B．it’s better to live in the towns
C．the brain contracts if it is not used
D．the more one uses his brain, the sooner he becomes old

People have smoked cigarettes for a long time now. The tobacco which is used to make cigarettes was first grown in what is now part of the United States. Christopher Columbus, who discovered America, saw the Indians smoking. Soon the dried leaves were transported to Europe . In the late 1800s, the Turks made cigarettes popular.
Cigarette smoke contains at least two harmful substances, tar and nicotine. Tar, which forms as the tobacco burns, damages the lungs and therefore affects breathing. Nicotine, which is found in the leaves, causes the heart to beat faster and increases the breathing rate. Nicotine in large can kill a person by stopping a person’s breathing muscles. Smokers usually take in small amounts that the body can quickly break down.
Nicotine can make new smokers feel dizzy(頭暈) or sick to their stomachs. The heart rate for young smokers increases 2 to 3 beats per minute. Nicotine also lowers skin temperature and reduces blood flow in the legs and feet. It plays an important role in increasing smokers’ risk of heart disease and stroke.
Smoking cigarettes is dangerous. Cigarette smoking was the cause of lung cancer and several other deadly diseases.
小題1:.
Tobacco first appeared in_________.
A．AsiaB．Africa
C．EuropeD．America
小題2:.
What is the main purpose of the first paragraph?
A．To tell us the bad effects caused by smoking cigarettes

C．To let us know what the cigarettes are made from
D．To tell the readers that Columbus found the Indians smoking
小題3:.
._________doesn’t make one’s heart beat as usual.
A．TarB．Nicotine
C．Lung diseaseD．Leave
小題4:.
The following effects are caused by Nicotine EXCEPT that________.
A．It can make new smokers feel dizzy or sick to their stomachs
B．It lowers skin temperature
C．It causes the heart to beat less fast
D．Nicotine will probably kill a person if a smoker takes in too much of it.

The other day at a supermarket, I saw a naughty child of about six crying loudly, falling to the floor and refusing to move. All the while the troubled mother was trying to persuade him to behave well but failed. A little smack(打)on his bottom would have worked ,I thought.
Teenagers also cause discipline(紀律)problems. As a teacher I had a 16-year-old student who had fallen in love with a waiter at a fast-food restaurant. In fact, she had left home to stay with him. So we decided to put her in the school hostel .She refused. When she heard her mother begging her to stay in the school hostel, she turned around and said: “Why don’t you stay in the school hostel if you like it so much?”
My hands were going to slap her for being so rude but the poor mother continued to cajole her , hoping the gentle persuasion would work wonders. It did not. Later I heard that she had run away from home again.
The list goes on and on. Could it be that today’s parents are so softer and believe that they must not rod(棍棒懲罰)their children for fear of the bad results? Or do they really believe that the children will get rid of the bad habits and behave well as they grow older? I beg to disagree. I believe it is the parents’ duty to discipline the children even at a young age.
My children who are now adults will prove the fact that I used the rod when I thought it necessary. Later when they went abroad, they told their university friends how they were disciplined. Their friends were shocked and said that I could be charged with child abuse. However ,my daughter showed great respect for me when she told them that she would not be where she was today if not for my strict discipline.
小題1:According to the passage, the author would probably________.
A．beat the children every dayB．treat the children in a soft way
C．leave the children as they areD．punish the children when necessary
小題2: The underlined word cajole” (in para.3)means_______.
A．persuadeB．scoldC．forgiveD．punish
小題3:In the author’s opinion, how should parents make their children grow up well?
A．rod their childrenB．punish their children
C．discipline their childrenD．discipline and punish their children if necessary
小題4:Which of the following is TRUE according to the passage?
A．The naughty boy’s mother hit him
B．The teacher’s daughter lived with her mother
C．The daughter was thankful for her mother’ strict discipline
D．The author was charged with child abuse by the daughter’s friends

Some of the planet’s most precious animals and plants are disappearing, according to the World Conservation Union (IUCN). The group, based in Switzerland, works with governments and experts to protect threatened species. On September 12, the IUCN released its Red List, a list of species at greatest risk of extinction.
The list includes 41,415 animals and plants. The IUCN says that habitat destruction, hunting and other causes threaten one in four mammals, one in eight birds and one in three amphibians(兩棲動物).
Who is to blame?
Scientists believe that 99 percent of threatened species are at risk because of human activity. “We are losing animals and plants at a high rate,” says Julia Marton-LefEevre, director general of the IUCN. “We need to change our behavior.” Warmer oceans and over-fishing are changing sea life. This year for the first time corals(珊瑚) made their appearance on the list. The gharial, a crocodile living in India and Nepal, has lost almost 60 percent of its population in the last 10 years. It is a victim（受害者）of habitat destruction.
Still, the news is not all bad. Thanks to efforts made to protect it, the Mauritius echo parakeet, a bird once endangered, has seen an increase in its population. “This shows that protection methods can work,” says Marton-LefEevre. “That’s the message we want to send to young people.”
In China the new reserve（保護區(qū)）itself is part of green efforts that have seen more than 2,400 nature reserves of various kinds being set up, covering more than 15 percent of the nation's land area, official figures showed.
"The country's natural resources(資源) have benefited from conservation," said Lei Guangchun, director of the nature reserve department of Beijing Forestry University. "It is a big increase nowadays compared with other countries." Lei said.
The total areas of China’s natural reserves have covered 1.38 million km2, which accounts for 15.4% of China’s area, higher than both the world average（平均水平） of 11% and the rate in most developed countries.
Li Zhong, an official in charge of the nature reserves office with the State Forestry Administration, thought it was important to increase investment（投資） in such reserves at all levels.
小題1:What do we know about the IUCN?
A．A union for listing animals and plants on the earth
B．A group of volunteers who are interested in wildlife
C．An organization concerning the protection of rare species' survival
D．A government made up officials, scientists and experts
小題2: What can be concluded from the passage?  
A．All the protection methods can’t work.
B．The IUCN does most of the protection.
C．The efforts China makes has paid off.
D．Enough is done in wildlife protection.
小題3:Which of the following is not the cause of the disappearance of the animals?
A．Bad weatherB．Over-hunting C．Warmer oceansD．Habitat destruction
小題4:Which of the sentence is NOT true?
A．China has been paying great attention to protecting the natural resources.
B．China has set up a lot of natural reserves.
C．The natural reserves in China cover more than 15 percent of the nation's land area.
D．The rate of China's natural reserves is lower than the average of the world.

Humpback whales
Humpback whales are sometimes called performers of the ocean. This is because they can make impressive movements when they dive. The name “humpback”, which is the common name for this whale, refers to the typical curve shape the whale’s back forms as it dives.
Sometimes the humpback will dive with a fantastic movement, known as a breach. During breaching the whale uses its powerful tail flukes to lift nearly two-thirds of its body out of the water in a giant leap. A breach might also include a sideways twist with fins stretched out like wings, as the whale reaches the height of the breach.
A humpback whale breathes air at the surface of the water through two blowholes which are located near the top of the head. It blows a double stream of water that can rise up to 4 meters above the water.
The humpback has a small dorsal fin located towards the tail flukes about two-thirds of the way down its back. Other distinguishing features include large pectoral fins, which may be up to a third of the body length, and unique black, and white spots on the underside of the tail flukes. These markings are like fingerprints: no two are the same.
Humpback whales live in large groups. They communicate with each other through complex “songs”.
Quick Facts
Size:
14m~18m in length
30~50 tons in weight
Living environment:
Open ocean and shallow coastline waters
Migration:
From warm tropical (熱帶的) waters, where they breed, to cold polar waters, where they eat.
Diet:
Shellfish, plants and fish of small size
Hunting:
Sometimes in groups, in which several whales form a circle under the water, blowing bubbles that form a “net” around a school of fish. The fish are then forced up to the surface in a concentrated mass.
Current state:
Endangered: it is estimated that there are about 5000~7000 humpback whales worldwide.
 
小題1:According to Quick Facts, a humpback whale ______.
A．cannot survive in waters near the shore
B．doesn’t live in the same waters all the time
C．lives mainly on underwater plants
D．prefers to work alone when hunting food
小題2:To make a breach, a humpback whale must ______.
A．use its tail flukes to leap out of the water
B．twist its body sideways to jump high.
C．blow two streams of water
D．communicate with a group of humpbacks.
小題3:From the passage we can learn that a humpback whale ______.
A．has its unique markings on it tail flukes
B．has black and white fingerprints
C．gets its name from the way it hunts
D．is a great performer due to its songs
