There is much discussion about the necessity of daily homework for students. Some say homework is necessary since only practice 1. (make) perfect, while others disagree. In my opinion, daily homework is necessary for students. However, this might be misleading that one may believe all forms of homework 2.(be) necessary. Actually, only proper amount of homework in proper form is _3. (accept); some homework may not only fail to help the students, but on 4. contrary bore them so much _5. they may lose their interest in studying. “Proper” homework, in

my opinion, should vary in its forms, 6. might be some extensive reading, a paper, or even just a game, as well as other ordinary exercise. And it should leave enough _7. (free) to the students so that they could do things they really like to do with self?motivation, rather than unwillingness. We should always remember that homework is something for us to guide the students, rather than _8. (drive) them. Only if a teacher 9. (keep) this 10. his/her mind, the homework could be of the most help to the students.

根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。有两项为多余选项。

1. From 18-25, according to I.Q. scores;but you are wiser and more experienced with increasing age. You are smartest in your 20's; around 30, your memory begins to go down, particularly your ability to perform mathematical computations(数学计算). 2. Your vocabulary at the age of 45, for example, is three times as great as when you graduated from college. At 60, your brain has almost four times as much information as it did at the age of 21.

3. You have the best physical sense of yourself from 15 to 24; the best professional sense from 40 to 49. Before the age of 24, we believe that our happiest years are yet to come;over 30,we believe that they are behind us. A National Health survey agrees: after the age of 30, we become more realistic and do not view happiness as a goal in itself. If we keep our health, achieve professional and emotional goals, happiness, we feel, will follow.

4. Generally between 30 and 39, but the peak (顶峰)varies with different professions(职业). Mozart wrote a symphony and four sonatas by the age of 8, and Mendelssohn composed his best?known work A Midsummer Night's Dream at 17, but most of the great music was written by men between 33 and 39.

Even if trees cannot walk, they are still on the move.

In parts of the Arctic, entire forests are moving northward. Across the Arctic, temperatures are rising faster than anywhere else in the world. As that happens, the tree line that marks where forests stop and the treeless tundra (冻原) starts has been shifting northward. Trees growing along the tree line must protect themselves from the cold wind. To do this,_plants tend to grow horizontal (水平的) branches low to the ground. The energy it takes for trees to grow this way means they don't have enough energy to make seeds.

But as Earth's climate has been warming, trees no longer have to just grow horizontally. Many can instead grow up toward the sky. This takes less energy. And with all that leftover energy, these trees have started producing more seeds. This happens especially in places where white spruce (白云杉) grows.

White spruce, which is a North American tree, is quite able to produce a lot of seeds, which can move long distances in the wind. When wind?blown seeds end up on the tundra beyond the tree line, they eventually can sprout(发芽) new trees. This explains how a forest can move. Of course, the process would work only if the tundra were warm enough. But in recent years, the whole planet has been warming.

New trees will provide shelters for some snow. Keeping the sun's rays from making the white surface disappear. Instead, the trees absorb the sun's heat. This warms the surrounding air. The extra warmth encourages even more trees to produce seeds. That further boosts a forest's ability to expand. In addition, more trees will trap more snow, preventing much of it from being blown away. Snow can trap heat in the soil below, which encourages trees to grow. The recent rise of temperatures has helped more trees grow past the tree line. People worry about impacts on the animals that depend on frozen conditions for food and shelter.

1.What is the main cause of the trees in the Arctic moving northward?

A.The shrinking of northern tundra.

B.The rising temperature.

C.The fierce and cold wind.

D.The abundant resources in the north.

2.What does the underlined word “this” in Paragraph 2 mean?

A.To produce more seeds.

B.To move northward.

C.To respond to the climate change.

D.To protect themselves from the cold wind.

3.What can be inferred from the last paragraph?

A.New trees can trap the snow, which may make the soil colder.

B.The trapped snow prevents new trees from producing more seeds.

C.New trees can make the surrounding air warmer.

D.New trees can bring more food and shelter to local animals.

4.The passage is most probably taken from ________.

A.a science report B.a health report

C.a fashion magazine D.a children's magazine

The spread of Western eating habits around the world is bad for human health and the environment. These findings come from a new report in the journal Nature.

David Tilman, a professor of ecology at the University of Minnesota, America, examined information from 100 countries to identify what people ate and how a diet affected health. He noted a movement beginning in the 1960s. He found that as nations industrialized (工业化), population increased and earnings rose, more people began to adopt what has been called the Western diet.

The Western diet is high in sugar, fat, oil and meat. By eating these foods, people began to get fatter and sicker. David Tilman says overweight people are at greater risk of noninfectious diseases like diabetes (糖尿病) and heart disease.

Unfortunately when people become industrialized, if they adopt this Western diet, they are going to have these health problems, especially in developing countries in Asia. China is an example where the number of diabetes cases has been jumping from less than one percent to 10 percent of the population as they began to industrialize over a 20­year period. And that is happening all across the world, in Mexico, in Nigeria and so on.

And, a diet bad for human beings is also bad for the environment. As the world's population grows, more forests and tropical (热带的) areas will become farmlands for crops or grasslands for cattle. We are likely to have more greenhouse gas in the future from agriculture than that coming out of all forms of transportation right now.

Mr. Tilman calls the link between the diet, the environment and human health, “a trilemma” — a problem offering a difficult choice. He says one possible solution is leaving the Western diet behind.

1.According to the passage, more greenhouse gas might be given off in the future from ________.

A.transportation B.developing countries

C.agriculture D.developed countries

2.David Tilman believes that ________.

A.the diet, the environment and human health are closely connected

B.the Western diet is the only choice as the nation industrializes

C.people in tropical areas are more likely to have heart disease

D.traditional diets are more balanced than the Western diet

3.We can infer from the passage that ________.

A.Nigeria has the largest number of diabetes cases

B.overweight people are at higher risk of infectious diseases

C.the examined information comes from developing countries

D.industrialization contributes to the spread of the Western diet

4.The main purpose of the passage is to ________.

A.call on us to protect the environment

B.warn us of the danger of the Western diet

C.remind us of the importance of health

D.advise us to have a balanced diet
