Whales live in the ocean, but they are not fish. They are warm-blooded mammals and must have air to breathe. The babies are born alive and drink milk from the mother's body. It took millions of years for the whale to develop as it is today.
Every spring groups of whales swim hundreds of kilometers to warm places to bear their young. Each group goes to the same place every year. The mothers take very good care of their babies. The fully grown whales are very gentle and playful with each other, and with humans. They “talk” to each other with a high noise that  sounds beautiful. This“talking” can be heard for more than 300 kilometers in open waters.
Yet humans kill over a hundred whales a day. They kill them to make whale oils and a lot of other things. Killing them is a modern business with modern machines and even harpoons( 魚叉炮) that explode( 爆炸) inside the whales. A whale dies very slowly and in great pain. Some ships kill every whale they can find, even the mothers and babies. Then there are no young whales to grow up or to bear more young.
小題1:A commonly mistaken belief is that ____.
A．whales are mammals
B．whales must have air to breathe
C．whales' babies drink milk
D．whales are fish
小題2:In the passage “mammals” refer to ____.
A．the animals which live in water

Everybody hates rats(老鼠). But in the earthquake capitals of the world—Japan, Los Angeles, Turkey—rats will soon be man’s new best friends.
What happens after an earthquake? We send in rescue dogs. Why? Because they can smell people. They help rescuers to find living people. But dogs are big and they can’t get into small spaces. So now a new research project is using a smaller animal to save lives: the rat.
How does it work? First, the rat is trained to smell people. When this happens, the rat’s brain gives a signal(信號). This is sent to a small radio on its back and then the rescuers follow the radio signals. When rat’s brain activity jumps, the rescuers know that someone is alive. The rat has smelled that person.
Although there are already robots which can do this job, rats are better. Christian Linster at Cornell University, New York, says, “Robots’ noses don’t work well when there are other smells around. Rats are good at that. ” Rats can also see in the dark. They are cheaper and quicker to train than dogs, and unlike robots, they don’t need electricity!
The “rat project” is not finished, but Julie Ryan of International Rescue Corps in Scotland says, “It would be fantastic. A rat could get into spaces we couldn’t get to, and a rat would get out if it wasn’t safe. ” Perhaps for the first time in history, people will be happy to see a rat in a building, but only after an earthquake, of course.
小題1: In the world earthquake capitals, rats will become man’s best friends because they can ______.
A．take the place of man’s rescue jobs
B．find the position of people alive who are trapped in buildings
C．serve as food for people alive who are trapped in buildings
D．get into small spaces
小題2:From the third paragraph we know the rescuers can judge a person is alive by ______.
A．the noise made by the rat
B．the rat’s unusual behavior
C．the signal sent by the radio on the rat’s back
D．the smell given off by the person
小題3:In doing rescue jobs, ______.
A．rats smell better than dogs
B．dogs don’t need to be trained to smell people
C．robots’ sense of smell can be affected by other smells around
D．rats can see in the dark and they are smaller than robots
小題4:Rats have all the following advantages EXCEPT that ______.
A．they are more fantastic than other animals
B．they are less expensive to train than dogs
C．they don’t need electricity
D．they are small and can get into small places

Common sense would tell us that physically active children may be more likely to become active and healthy adults.
In the United States, elementary and middle schools are advised to give students two and a half hours of physical activity a week. That is what the Centers for Disease Control and Prevention and the American Heart Association recommend. They say high schools should provide about four hours of physical activity each week.
Yet many schools across the country have reduced their physical education programs. Just this week, a study reported that life expectancy has fallen or is no longer increasing in some parts of the United States. The situation is worst among poor people in the southern states, and especially women. Public health researchers say it is largely the result of increases in fatness, smoking and high blood pressure. They also blame differences in health services around the country.
In 2006, a study found that only four percent of primary schools provided daily physical education all year for all grades. This was true of eight percent of middle schools and two percent of high schools. The study also found that twenty-two percent of all schools did not require students to take any P.E.
Charlene Burgeson , a health expert says one problem for P.E. teachers is that schools are under pressure to put more time into academic subjects. Also, parents may agree that children need exercise in school. Yet many parents today still have bad memories of being chosen last for teams because teachers favored the good athletes in class.
But experts say P.E. classes have changed. They say the goal has moved away from competition and toward personal performance, as a way to build a lifetime of activity. These days, teachers often lead activities like weight training and yoga.
Some parents like the idea of avoiding competitive sports in P.E. class. Yet others surely dislike that idea. In the end, schools may find themselves in a no-win situation.
小題1: The underlined word “expectancy” in Paragraph 3 probably means “       ”                            
A．qualityB．lengthC．exceptionD．depth
小題2:According to the passage which of the following may not lead to poor health?
A．Fatness.B．Smoking
C．High blood pressure.D．Health service
小題3: What can be inferred after you read this passage?
A．Physical activities are becoming more and more popular in American schools.
B．All the schools provided daily physical education all year for all students.
C．Parents think children need physical education for their bad memories.
D．Students spent less time on physical education for academic pressure.
小題4: What is the main idea about this passage?
A．P.E. is the most important subject for all students.
B．P.E has changed its goal for some reasons in America.
C．It introduces us the present situation of P.E in American schools and its cause.
D．P.E can help students improve their academic subjects.

“ I’d like to be at a healthier weight , ” a friend told me . “ But we just don’t have the money to buy expensive diet foods and there isn’t enough money to join a gym .” Many people feel that way—that a healthy diet and exercise plan is out of reach because of their high cost . Don’t lose hope ! We’ll be looking at ways to make healthy choices without spending too much money .
First you don’t need to buy the expensive pre-prepared “ diet foods . ” Back in the early 1970s when I started housekeeping , 90% of the food I bought was ingredients . Very few things were preprocessed（預處理的）. Now 90% of the food you find in the store is quick food . That’s a bad thing .
Quick foods like boxed “ just add hamburger ” meals have had the fiber removed to make them faster to prepare . Take a look at the label on that box . It often has low numbers listed under “ fiber ” because fiber takes longer to digest . If the low fiber meal is digested , the result is that your body begins to store fat . Besides , your body is short of nutrients（營養(yǎng)物質）. You will be driven to eat more to try to make up for the low quality of the food you are eating .
And then there are the chemicals the producers add to the quick meals to make them palatable . If not , the stuff would taste like cardboard and you wouldn’t enjoy it . However , these chemicals certainly aren’t good for your health .
What’s the answer ? Buy whole ingredients and give up the expensive , low nutrition , processed foods . Do the cooking yourself and you will have control over what is in your food —and it will cost less , too .
小題1:People who find it hard to get a healthier weight think        .
A．they had too much diet foods
B．they didn’t make a detailed plan
C．they have no time to do exercise in gym
D．they can’t afford diet foods and to exercise in gym
小題2: The author doesn’t like quick food mainly because       .
A．it contains too much fatB．it makes people eat less
C．it has low fiberD．it takes longer to digest
小題3:The underlined word “ palatable ” in Paragraph 4 probably means “       ”.
A．freshB．deliciousC．healthyD．simple
小題4:The author suggests in the text that people should       .
A．control the amount of food
B．eat more processed foods
C．cook food for themselves
D．choose cheap ingredients
小題5:Which of the following best shows the structure of the passage ? （①="Paragraph" 1,

Mothers can still offer comfort, even from a distance, a new study has found. The results show that simply hearing their mothers’ voice over the phone works just as well at calming the nerves of stressed children as a real-life pat on the shoulder.
The soothing（撫慰的）effect is most likely due to the release of the hormone（荷爾蒙）, oxytocin（催生素）, in the brain, the researchers say. This “l(fā)ove hormone” is known to quell stress and is likely to be involved in social connections, including those between a mother and a child.
Previous work has revealed that this hormone is released during physical contact with a mother. “But it’s clear from these results that a mother’s voice can have the same effect as a hug, even if she isn’t actually standing there,” said the researcher, Leslie Seltzer, a biological scientist.
Seltzer tested a group of 61 girls, aged 7 to 12, by having them make an unprepared speech and solve a series of maths problems in front of a group of strangers, sending their hearts racing and levels of cortisol—a hormone associated with stress—soaring.
Facing a challenge like that raises stress levels of a lot of people. Once stressed, a third of the girls were comforted in person by their mothers with hugs. A third of the girls watched an emotionally neutral 75-minute video. The rest were handed a telephone with their mothers on the line.
For the girls who interacted in person or over the phone with their mothers, the levels of the “l(fā)ove hormone” rose significantly, and the stress-marking hormone was washed away. This effect didn’t show up for participants who watched the video.
Seltzer is now testing the amount of oxytocin released with other communication methods—like text messaging—and hopes to see the research spread out from human subjects. “It’s not just us, of course. Lots of very social species have voices,” she said. “on the one hand, we are curious to see if this effect is unique to humans. On the other, we’re hoping researchers who study vocal communication will consider looking at oxytocin release in other animals and apply it to broader questions of social behavior and evolutionary biology.
小題1:Mothers’ voice over the phone can reduce children’s nerves according to the study, because           .
A．children can imagine their mothers’ hugs on the line
B．children enjoy their mothers’ voice and forget their worries
C．mothers are good at comforting their children, even on the phone
D．mothers’ voice can promote the release of the love hormone
小題2:The underlined word “quell” in the second paragraph probably means “         ”.
A．cause or bringB．delay or direct
C．stop or reduceD．develop or train
小題3: From the study, we know that                .
A．the level of cortisol determines how stressed a person is
B．the 61 girls were divided into two groups in the research
C．the recent study had the same results as the previous one
D．watching a video is the best way to reduce one’s stress
小題4:From the last paragraph, we can conclude that          .
A．text messaging has the same effect on oxytocin release as telephoning
B．the effect of a mother's voice on oxytocin in animals is still not known
C．the effect of communication on stress is unique to humans
D．the research has been applied to social behavior and evolutionary biology

In old times,  man considered lightning to be one of the great mysteries(神秘事物)of nature.  In fact a single flash of lightning 1. 6 kilometers long has enough electricity to light one million lamps.    
The American scientist, Benjamin Franklin, was the first to suggest that lightning is in fact electricity formed between the earth and clouds high above. It happened in 1752. In the same year, he also built the first lightning rod(避雷針)to protect buildings from being struck by lightnings.    
Modern science has discovered that lightning is very strong and powerful. A lightning between a cloud and the earth may be as long as 13 kilometers, and travels at a speed of 30 million meters per second.  Scientists have the opinion that there are about 2, 000 million flashes of lightning per year. In the United States alone, it kills almost one person per day.     The safest place to be in during an electrical storm is a closed car. Outside, one should go close to low ground for cover and not stop under a tree. Also one should stay out of water and away from metal fences. Inside a house people should keep away from open doorways and windows and not touch wires or metal things.
小題1:From this passage we know lightning is_______ .
A．one of the great mysteries of nature

A common misconception (誤解) -about scholarships is that they are only available for the smartest students with the highest GPAs. However, this just isn't even close to true. There are scholarships out there for every type of student seeking a college education. Let's take a look at each type a bit more in depth.
Academic Scholarships
Academic scholarships are also often referred to as merit (優(yōu)點) scholarships, though a merit scholarship can mean anything that has some level of contest to it. These are fox; the students with the 4.0 GPAs, the years as a part of several extracurricular (課外的) activities and the well- rounded applications. They typically have the highest payouts and are considered very well- known as they are often national awards.
Athletic Scholarships
For students with strong academics (學業(yè)的) and physical skills, athletic scholarships are the way to go. There is practically a scholarship for every single sport, from volleyball to football; gymnastics to cheerleading. So, if you are good at anything physical, you should definitely pursue an athletic scholarship.
Scholarships for Minorities
There are also many scholarships for minorities available. Some of these are general and for "all minorities as a collective whole, while others are intended for individual ethnic (種族的) groups. It is also a good idea to apply for a minority scholarship if you are part of fully of a certain ethnicity. You will get to represent your culture and possibly win money -- what more could you ask for?
Scholarships for Women
As with the scholarships for minorities above, there are also scholarships specifically for women. Since colleges were dominated (主宰) by men for many years, scholarships have been created for strong, career-minded women that need assistance paying for college expenses. If you are female, it is strongly recommended you pursue a scholarship for women. Moreover, scholarships for women are typically available in just about any field. Be specific!
小題1:In the author's opinion, ______.
A．most people are well - informed about scholarships
B．most people think scholarships should go to the smartest students
