We can always hear voices comparing the education systems in China and the US. It's true that1.exist a lot of differences, but this cannot be an excuse2.having a passive attitude toward studying in China.

When I came back from the US last year and continued my senior middle school education in China, I sensed many great differences. I thought that school in China was too hard for3.(we) students, and that we didn't get to do enough fun exercise except running around playgrounds together. My mom had a long talk with me. After that, I realized that though high school life in China is harder, it can give us4.(much). The pressure helps us learn the true meaning of competition5.we step into society. It gives us a strong heart and6.(teach) us to step forward no matter what the7.(real)is. It's like climbing a mountain. You might feel dizzy and nervous, but the top is always there8.(wait) for you as long as you are strong enough—9.(take) one more step.

We complain10.(main) because we can't see the whole picture. We all need to understand that success takes efforts and tears.

Big trees are incredibly important ecologically. For a start, they provide food for countless other species and shelter for many animals. With their tall branches in the sun, they capture vast amounts of energy. This allows them to produce massive crops of fruit and flowers that sustain much of the animal life in the forest.

Only a small number of tree species have the genetic ability to grow really big. The biggest are native to North America, but big trees grow all over the globe, from the tropics to the forests of the high latitudes(纬度). To achieve giant size, a tree needs three things: the right place to establish its seeding, good growing conditions and lots of time with low adult death rate. Lose any of these, and you will lose your biggest trees.

In some parts of the world, populations of big trees are dwindling because their seedings cannot survive. In southern India, for instance, an aggressive non-native bush, Lantana camara, is invading the floor of many forests. Lantana grows so thickly that young trees often fail to take root. With no young trees to replace them, it is only a matter of time before most of the big trees disappear.

Without the right growing conditions, trees cannot get really big and there is some evidence to suggest tree growth could slow in a warmer world, particularly in environments that are already warm. Having worked for decades at La Selva Biological Station in Puerto Viejo de Sarapiqui, Costa Rica, David and Deborah Clark and colleagues have shown that tree growth there declines markedly in warmer years. “During the day, their growth shuts down when it gets too warm, and at night they consume more energy because their metabolic(新陈代谢的)rate increases,” explains David Clark. With less energy produced in warmer years and more being consumed just to survive, there is even less energy available for growth.

The Clarks’ theory, if correct, means tropical forests would shrink over time. The largest, oldest trees would progressively die off and tend not to be replaced. According to the Clarks, this might cause a destabilization of the climate; as older trees die, forests would release some of their stored carbon into the atmosphere, causing a cycle of further warming, forest shrinkage and carbon emissions.

Besides, big trees face threats from elsewhere.

1. All the following factors are a must for making big trees EXCEPT_________.

4.What will the author most probably discuss after the last paragraph?

A. Comparison between common trees and big ones.

B. The effect of human activities on big trees.

C. Benefits of big trees to the whole atmosphere.

D. More threats to the existence of big trees.

根据内容, 从对话后的选项中选出能填入空白处的最佳选项,选项中有两项多余选项。

It doesn't come as a surprise to you to realize that it makes no difference what you read or study if you can't remember it.You just waste your valuable time.1.One dependable aid that does help you remember what you study is to have a specific purpose or reason for reading.

Why does a clerk in a store go away when your reply to her offer to help is, "No, thank you.I'm just looking."? Both you and she know that if you aren't sure what you want, you are not likely to find it.But suppose you say instead, "Yes, thank you.I want a pair of sun glasses." She says, "Right this way, please."

2.If you choose a book, "just looking" for nothing in particular, you are likely to get just that—nothing.But if you do know what you want, you are almost sure to get it.Your reasons will vary; they will include reading or studying "to find out more about", "to understand the reasons for" and "to find out how".

3.Before you start to study, you say to yourself something like this, "I want to know why Stephen Vincent Benet happened to write about America".Because you know why you are reading or studying, you relate the information to your purpose and remember it better.

4.At least two important processes go on at the same time.As you read, you take in ideas rapidly and accurately.But at the same time you express your own ideas to yourself as you react to what you read.You have a kind of mental conversation with the author.

This additional process of thinking about what you read includes evaluating it, relating it to what you already know, and using it for your own purposes. 5.One part of critical reading, as you have discovered, is distinguishing between facts and opinions.Facts can be checked by evidence, Opinions are one's own personal reactions.Another part of critical reading is judging sources.Still another part is drawing accurate inferences.

A.This is the way it works.

B.Maybe you have already discovered some clever ways to keep yourself from forgetting.

C.It is important for students to have a positive attitude to their study.

D.You remember better when you know what you' re reading.

E.In other words, a good reader is a critical reader.

F.It’s quite the same with your studying.

G.Reading is not one single activity.
