When you take a walk in any city, you often see a lot of people walking dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reason why people keep a dog has changed. In the old days people used to train dogs to protect(保護(hù)) themselves against attacks by other beasts. Later they came to realize that a dog was not only useful for protection but willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without permission.
These days people in the city need not protect themselves against attacks from animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery（搶劫）. But the most important reason is for companionship. For a child, a dog is a best friend when there are no friends to play with. For young couples, a dog is their child when they have no children. For old couples, a dog is also their child when their natural children have grown up. So the main reason why people keep dogs has changed from protection to friendship.
67. According to the passage, in the old days people trained dogs ______ .
for protection against robbery
just for fun
for companionship
for protection against other animals
68. The word "companionship" may mean ______ .
A. native     B. advice     C. friendly relationship（關(guān)系） D. usage
69. The dogs were used for hunting because ______ .
A. they were good hunters
B. they obeyed their masters
C. they were useful for protection
D. they did not eat other animals
70. The most important reason for people to keep dogs now is they ______ .
A. need companion
B. like children
C. enjoy hunting
D .want to protect themselves
71. We can infer from the passage that ______ .
A. dogs can be helpful to those who need company
B. city people always feel lonely
C. dogs can be boring （厭煩的）
D. the city can be a very dangerous place

         All of us eat every day, but most of us don’t understand nutrition. We often make mistakes in talking about good diet.
For example, many people think that foods such as rice, bread and potatoes will make one grow fat. In fact, these foods are very good to one’s health. They are good sources of many vitamins. And in comparison with steak and beef, they contain less amount of calories.
Some people don’t like canned(罐裝的) or frozen vegetables, because they think fresh vegetables cooked at home are always better. This is again wrong. In fact, whether the vegetables are good or not depends more on how they are prepared. Overcooking, for example, destroys good qualities of vegetables. Vegetables cooked in too much water can lose a large amount of vitamins.
It is widely believed extra vitamins provide more energy. But taking more than the body needs doesn’t make it function better.
It is also wrong to say that vegetables grown in poor, worn-out soil are lower in vitamins than vegetables grown in rich soil. The vitamins in our foods are in the plants themselves. They don’t come from the soil. However, the minerals(礦物質(zhì)) in a plant depend on the minerals in the soil.
In short, there are many false ideas about nutrition. We need to correct them.
46. This passage is mainly about_______.
A. nutrition                B. vitamins                C. vegetables            D. health
47. Rice, bread and potatoes do good to people’s health mainly because_______.
A. they make people fat                              B. there are lot of vitamins in them
C. they contain less amount of calories compared with steak and beef.
D. both B and C.
48. Why don’t some people like canned or frozen vegetables? Because______.
A. they think fresh vegetables contain less vitamins
B. they think fresh vegetables contain more vitamins than the canned or frozen ones
C. they don’t think the canned or frozen vegetables are fresh
D. they don’t think the canned or frozen vegetables taste as good as the fresh ones
49. Which of the following is true according to the passage?
A. Many people know almost everything about nutrition.
B. Food such as rice, bread and potatoes make people fat.
C. vegetables grown in poor worn-out soil may have the same amount of vitamins as vegetables grown in rich soil.
D. extra vitamins provide less energy.
50. The point of the passage is that______.
A. the minerals in a plant depend on the minerals in the soil
B. people make mistakes when talking about good diet
C. taking more vitamins than the body needs doesn’t make it function better
D. vegetables cooked in too much water can lose a large amount of vitamins

Like cats, geckos（壁虎）always land on their feet. If they happen to fall from a wall or leaf they’ve been climbing, a quick move of the tail makes sure that they always land on their feet first, a new study finds.
Geckos are truly built for climbing: their feet have hairy toes that can fix themselves to a wall or other vertical（豎直的）surfaces. However, geckos’ feet can’t always keep hold and they may fall to the ground. When geckos fall or jump off a wall, they always land stomach-side down. Geckos’ long tails become necessary during their falls, the new study shows.
Researchers did an experiment. They placed geckos up-side-down on the underside of a leaf. When they lost their foothold and fell, the geckos pitched （傾斜）their tails for balance. They then rotated（旋轉(zhuǎn)）their tails to make their bodies rotate. As soon as they were right-side up, they stopped rotating. On average, it only took the geckos about a tenth of a second to right themselves so that they would land on their feet.
Cats use a different way to land on their feet after a fall. As their tails don’t have the power like geckos’ tails, cats can’t use them to right themselves. Instead they twist their bodies around mid-air.
Engineers are trying to build a robot that imitates the geckos’ climbing ability. A tail will be fixed to the robot to allow it to keep balance.
54. What do we know about geckos?
A. Their toes make it possible for them to walk on walls.
B. Their tails can fix them to a wall or other vertical surfaces.
C. They often land on their backs when they jump off walls.
D. It takes them a second to right themselves in mid-air.
55. How do cats avoid their injury during a fall?
A. By twisting their bodies.                 B. By fixing their toes to the ground.
C. By using their tails to right themselves.        D. By landing upside-down.
56. Geckos’ special abilities have given engineers some new ideas to _________.
A. allow robots to climb vertical surfaces       
B. reproduce geckos like robots
C. invent robots that can rotate on the ground
D. invent robots that can balance themselves using their tails
57. What is the text mainly talking about?
A. The interesting living habits of geckos.   B. The differences between cats and geckos.
C. Why geckos always land on their feet.      D. How geckos climb up vertical walls.

Watching television more than two hours a day early in life can lead to attention problems later in adolescence, according to a study released on Tuesday.
The roughly 40 percent increase in attention problems among heavy TV viewers was observed in both boys and girls. The link was established by a long-term study of the habits and behaviors of more than 1,000 children born in Dunedin, New Zealand, between April 1972 and March 1973.
The children aged 5 to 11 watched an average of 2.05 hours of weekday television. From age 13 to 15, time spent in front of the tube rose to an average of 3.1 hours a day.
"Those who watched more than two hours, and particularly those who watched more than three hours, of television per day during childhood had above-average symptoms of attention problems in adolescence," Carl Landhuis of the University of Otago in Dunedin wrote in his report, published in the journal Pediatrics.
Young children who watched a lot of television were more likely to continue the habit as they got older, but even if they did not the damage was done, the report said.
"This suggests that the effects of childhood viewing on attention may be long lasting," Landhuis wrote.
Landhuis offered several possible explanations for the association.
One was that the rapid scene changes common to many TV programs may over stimulate（刺激）the developing brain of a young child, and could make reality seem boring by comparison. "Hence, children who watch a lot of television may become less tolerant of slower-paced and more mundane tasks, such as school work," he wrote.
It was also possible that TV viewing may supplant other activities that promote concentration, such as reading, games, sports and play, he said.
Previous studies have linked the sedentary固定不動(dòng)的）habit of TV watching among children to obesity and diabetes, and another study in the same journal cited the poor nutritional content of the overwhelming majority of food products advertised on the top-rated US. children's television shows.
Up to 98 percent of the TV ads promoting food products that were directed at children aged 2 through 11 "were high in either fat, sugar, or sodium," wrote Lisa Powell of the University of Illinois in Chicago.
56. The recent survey shows that _________.
A. watching TV can cause all kinds of diseases for children
B. TV sets have played an important part in our daily lives
C. Watching TV over 2 hours a day early in life can cause attention problems later in adolescence
D. watching TV has side effects on children’s future
57. People used to think that _________.
A. watching TV more than 2 hours every day did good to children’s health
B. the sedentary habit of TV watching among children could easily lead to obesity and diabetes
C. the children wasn’t patient with their homework because of watching TV too much
D. it was very important for children to watching TV early in life
58. The underlined word “Hence” means _________.
A. In that case    B. And yet    C. On the contrary    D. For this reason
59. In Landhuis’ opinion, _________.
A. attention problems caused by watching TV during childhood may be hard to get rid of
B. how to develop children’s attention problems is a lasting problem
C. the key of settling attention problems is not watching TV too much
D. there shouldn’t have many food products ads on children's television shows

The first thing to remember about homework is that it needs to be done as soon as you get home from school. Since many parents do not give doses to help you sleep at night, the homework MUST be done first. If you have after-school activities, the homework should be done as soon as you get home. It is fine to allow for a snack break and also to allow for stretching breaks. Every kid of you really needs these little breaks.
Also, you should remember that it is your responsibility to do your homework. Next time you tend to depend on Mom and Dad for a roadmap, please try to struggle with it first, because it is good for you.
When you have questions, especially something about a science or a math problem, don’t always turn to your teacher! It is a good idea to struggle with them first and try to work them out. Sometimes, if this doesn’t work, look at the materials in the back of the book. They may guide you to pages and and understanding everything completely.
At last, while doing homework, don’t be looking away but continue working. Setting time limits often helps with this. Different ages decide different fair amounts of time. 10-15minutes is good for a child that’s age 6-8. A time of 20-30 minutes is about right for a child aged 9-12. Kids can achieve 30-45 minute intervals of study at age 13-15. This, of course, depends on your abilities to concentrate and stay on task.
60. The passage mainly tells children ________.
A. to do their homework quickly and properly
B. to limit their time of doing homework
C. not to turn to teachers when doing homework
D. not to look away while doing homework
61 Which of the following may have the same meaning as “struggle with them”?
A. fight against them         B. study them carefully
C. break away from them      D. show great interest in them
62. If you are a girl aged 14, the proper length of the homework time should be________.
A. 14 minutes    B. 25 minutes    C. 35 minutes     D. 50 minutes
63. The author seems to think ________.
