We learned that fossil fuels were formed before and during the time of the dinosaurs(恐龍). We are using up the fuels. We can save fossil fuels by protecting and finding ways to use energy from “endless sources”, like the sun and the wind. Some people suggest that we should start using hydrogen(氫).
Hydrogen is a colorless, smell-less gas that takes up 75 percent of the whole universe. Hydrogen is found on earth only in mixture with other elements such as oxygen, carbon and nitrogen. To use hydrogen, we must separate it from these other elements.
Hydrogen can be used in NASA’s space program as fuel for the spaceships, and in fuel cells that provide heat, electricity and drinking water for astronauts. Fuel cells are devices that directly change hydrogen into electricity. In the future, hydrogen could be used to fuel vehicles and aircraft and provide power for our homes and offices.
Hydrogen can be made from natural gas. An electrical current can also be used to separate water into its elements of oxygen and hydrogen. Some plants in the sea and bacteria(細(xì)菌) give off hydrogen through sunlight under certain conditions.
Hydrogen as a fuel is high in energy. Yet a machine that burns pure hydrogen produces almost zero pollution. NASA has used liquid hydrogen since the 1970s to drive rockets and spacecraft into orbit. Hydrogen fuel cells power the spacecraft’s electrical systems, producing clean by-product-pure water, which the crew drinks.
56. We can get hydrogen from the following EXCEPT ______ according to the passage.
A. natural gas    B. water                    C. creature in the sea         D. bacteria
57. Why could the hydrogen be used widely in the future?
A. Because it is of high quality.               
B. Because it has no pollution. 
C. Because it is easy to get it from all kinds of ways.      
D. Because there are much hydrogen existing in the universe.
58. The passage mainly tells us ________.
A. the usage of a new energy source        B. the future energy sources
C. a new energy source -h(huán)ydrogen       D. how to get the energy source
56-58 CBC   
56. C。從文章可以知道。我們可以從空氣、水、海洋植物和細(xì)菌中獲取氫。海洋生物太籠統(tǒng)了,所以選C。
57. B。從文章的最后一段可知,氫作為能源幾乎沒有污染。

The tea gardens in Sri Lanka are actually large estates(種植園). The best tea usually comes from plants grown on high grounds, the cool hilltops with rows and rows of tea plants. The plants are about one metre apart. The plant is often pruned so that it remains only 60 to 90 centimetres high. Pruning is important because it encourages the growth of tender shoots, or young leaves. It is from these shoots that the best tea is got.
Practically all the tea pickers are women. The estates prefer to employ women pickers because they are more careful. Their thin fingers can easily remove the twin leaves and new shoots from the plant, which are the parts used for processing(加工) tea. The pickers carry large baskets into which they throw their pickings. A skilled worker can harvest between 9 to 14 kilogrammes of tea leaves a day. Usually new shoots can be picked from the plants about every ten or fifteen days.
Processing tea shoots into the familiar dry tea leaves requires great care and skill .There are various methods of processing depending on the type of tea required .For black tea ,the young green leaves are first spread out o shelves to dry. This process removes much of its water and the leaves become soft. After this ,the leaves are passed through heavy rollers .This operation will press the leaves for juices which give the tea both its colour and taste .Then the leaves are spread out on floors and left to ferment (發(fā)酵)under wet conditions. Fermentation develops the rich taste of black tea .The fermented leaves are then dried with a hot-air blower until they become rolled-up black leaves .The final step is to sort and grade them before the black tea is ready for sale to countries all over the world.
68.In the first paragraph ,the word “pruning” means       .
A.regular cutting of the plants   B.frequent watering
C.regular use of chemicals        D.growing the plants high in the mountain
69.One of the reasons why women are employed to do the picking is that        .
A.they work harder than men do in the picking
B.they can throw their pickings more easily into the baskets
C.their fingers fit them better for the job.
D.they can more easily find the twin leaves.
70.How many processing steps are mentioned in the last paragraph?
A.Three.    B.Four.    C.Five.    D.Six.
71.What is the writer’s purpose in writing the passage?
A.To introduce various methods of tea processing.
B.To persuade readers to buy tea from Sri Lanka.
C.To tell a story that had happened in the tea gardens.
D.To inform readers of tea growing ,picking and processing.

To extinguish (熄滅) different kinds of fires, several types of fire extinguishers have been invented. They must be ready for immediate use when fire breaks out. Most portable (手提式的) kinds operate for less than a minute, so they are useful only on small fires. The law requires ships, trains, buses and planes to carry extinguishers.
Since fuel, oxygen (氧氣) and heat must be present in order for fire to exist, one or more of these things must be removed or reduced to extinguish a fire. If the heat is reduced by cooling the material below a certain temperature, the fire goes out. The cooling method is the most common way to put out a fire. Water is the best cooling material because it is low in cost and easy to get.
Another method of extinguishing fire is by cutting off the oxygen. This is usually done by covering the fire with sand, steam or some other things. A blanket may be used do cover a small fire.
A third method is called separation, which includes removing the fuel, or material easy to burn, from a fire, so that it can find no fuel.
The method that is used to put out a fire depends upon the type of fire. Fires have been grouped in three classes. Fires in wood, paper, cloth and the like are called Class A fires. These materials usually help keep the fire on. Such fires can be stopped most readily by cooling with water.
68. If a fire breaks out on a bus, which of the follow should be ready there for you to use?
A. Sand           B. Water         C. A blanket.           D. An extinguisher.
69. To cover a small piece of burning wood with a basin in order to stop the fire is an example of         .
A. separating the fire                                 B. reducing the heat
C. removing the fuel                                 D. cutting off the oxygen
70. In choosing how to put out a fire, we should first be clear about          .
A. when it breaks out                                B. how it comes about
C. what kind it is                                       D. where it takes place
71. What would the author probably discuss in the paragraph that follows?
A. Another class of fires                                   B. Another type of extinguishers
C. How fires break out.                                D. How fires can be prevented.

D
Can trees talk? Yes --- but not in words. Scientists have reason to believe that trees do communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree  (柳樹) attacked in the woods by caterpillars (毛毛蟲) changed the chemistry of its leaves and made them tasteless so that the caterpillars got tired of the leaves and stopped eating them. The even more astonishing, the tree sent out a special vapor--- a signal causing its neighbors to change the chemistry of their own leaves and make themselves taste also terrible.
Communication, of course, doesn’t need to be always in words. We can talk to each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar (花蜜) for honey. So shy shouldn’t trees have ways of sending messages?
71.When attacked, a willow tree will protect itself by _______.
A. changing its leaves’ chemistry         B. changing its leaves’ color
C. talking to caterpillars                      D. sending a special vapor

My dad also taught me,by example,that a healthy lifestyle is important.He was hardly ever sick.But I don’l think my dad ever even had a cup of coffee.He barely touched alcohol.
He would say,“Boonnie,your voice is a reflection of your overall physical well-being.So if you want to sing well,take better care of yourself.” If I became hoarse(嘶啞)or caught a cold,he didn’t blame me directly:“Well,Bonnie,you know,if you’d get to sleep a little earlier,that would probably be a good idea.”When I decided to get unexcitable about 18 years ago,he told me.“See,
Bonnie,it's so great to see you in such strong voice all the time.”
He just did not complain,even when he was uncomfortable toward the end,from the pneumonia that eventually took his life.He simply made a choice to be positive and not negative.

C
Reading about history is nice, but finding ties to long-ago historical events in your own backyard is really exciting.
In their heavily populated area, neighbors Adam Giles,13, and Derek Hann.12, uncovered pieces of glass that looked quite different from what’s used today.“After digging about two feet down, I came across an interesting bottle,” Derek said.The bottle had a “pontil scar” on the bottle, an indication that it was hand-blown rather than machine made.It also had the name “Fraser” on one side.
Adam found remains of a green bottle and some very thick brown glass—again, far different from today’s.
After doing research on the computer, the boys contacted Aimee Wells of the county’s Cultural Resources office.She showed them a computer program that digitally puts old maps over modern satellite photographs.
Bingo! Their back yards were once part of a military(軍事的) encampment(營(yíng)地) called Camp Alger used by Ohio soldiers on their way to fight in the Spanish-American War in 1898.
So how do a few bottles get connected to a brief war that was more than a century ago? “We get there by good judgment,” Wells said.“We know the time period of the bottles and what happened in that area.” Anyone can dig a hole, but archaeologists seek a deeper understanding.How do objects found relate to things around them?
When Derek and Adam realized that a solider might have held that Fraser bottle 110 years ago, they wondered what he might have been thinking.What did he see as he looked around him? How did he pass the time waiting to go into battle?
Historical records show that while waiting for orders, the soldiers in and around Camp Alger played baseball, played instruments and walked seven miles to the Potomac River once a week for baths.A spread of strange fever forced the closing of the camp, and there are no buildings to study.“What’s left is only what’s in the ground,” said Wells.
Derek’s and Adam’s back yards have joined the 3,400 places listed on the county’s register of archaeological sites.The boys were given tips on how to dig effectively and safely, and on how to document the location of items found.
The official record of their finds serves as another piece of the puzzle for historians seeking to form a more complete story of what happened.
“Not everyone is going to have historical objects in their own yard,” Wells said.“That’s okay.Make your own time capsule and bury it.What would you want people to know about your life years from now?”
63.What is the passage mainly about?
A.How Adam Giles and Derek Hann dug out the remains of an ancient military encampment.
B.What Adam Giles and Derek Hann found in their back yard and its relationship with an encampment.
C.The great contribution Adam Giles and Derek Hann made to the cause of archaeology.
D.The tips on how to dig out ancient objects buried under the ground safely and effectively.
64.From the passage, we can see that the boy’s discovery _______.
A.includes all kinds of hand-made and machine- made glass.
B.has helped historians find out what happened in 1898.
C.couldn’t have been meaningful without Aimee Wells’ help.
D.has added the county to the list of archaeologist sites.
65.When Wells said “We get there by good judgment.” (Paragraph 6), she meant that_______.
A.they have established the ties to Camp Alger by finding out the time period of the bottles.
B.they have figured out how to get to the place where the brief war happened.
C.they have managed to dig out the bottles in the back yard safely with common sense.
D.they were able to locate the soldiers who used the Fraser bottles 110 years ago.
66.Which of the following fits the description of historical records?
A.The soldiers in and around Camp Alger delighted in playing basketball in their spare time.
B.When Camp Alger was forced to close, all the buildings there were destroyed.
C.The soldiers in and around Camp Alger often buried some bottles underground as time capsules.
D.Camp Alger was forced to close because of a spread of a strange fever.

An Australian company, Smart Car Technologies, has developed a system that lets drivers know when they’re speeding.When the technology becomes commercially available, it could help lead-footed drivers avoid tickets and also save lives.The company that developed the product hopes to convince Australian government agencies to put the technology into use in their automobile fleets.
The product, called Speed Alert, links real-time location data and speed obtained with the help of GPS(全球定位系統(tǒng)) to a database of posted speed limits stored in a driver’s PDA or programmable mobile phone.The setup of the product does not need to be hooked(鉤住) up to a car’s speedometer.In fact, it is entirely portable.It will also work with newer phones and PDAs that have built-in GPS receivers.If a driver exceeds(超過) the speed limit, the speed is shown and an alert sounds.
Michael Paine, an Australian vehicle design engineer and traffic safety consultant, was hired to analyze the product.He told Live Science  that his colleagues in the road safety field are “very enthusiastic” about what they’re now calling “intelligent speed alert.” Other research, according to Paine, shows that 40 percent of all traffic deaths involve speeding.There is also a potentially future use: “Since the system is so portable, it would be easy to make it a requirement for teenage drivers to always use a speed alert device when driving,” Paine said.“The system even has the function to record speeding violations(違背), so parents can monitor their teenage drivers.”
The product will soon go on sale in Sydney.
41.What’s the purpose of the new product_______.
A.To inform us of the new car system.     B.To introduce some improvement in cars.
C.To limit certain drivers to safe driving.   D.To popularize the built-in car system.
42.Lead-footed drivers refer to the ones        .
A.who drive too carelessly   B.that drive extremely fast
C.who are partly disabled     D.that drive too slowly
43.The second paragraph mainly talks about        .
A.the project of the built-in product     B.why the system becomes popular
C.the functions of GPS in cars       D.how the product is programmed
44.Which of the following is true of Speed Alert according to Michael Paine?
A.Most of the traffic deaths can be avoided. 
B.Speeding violations can be easily found out.
C.The system will excite some teenage drivers.
D.The product will not be available for adults.
