A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate.Without the forest cover，these areas would reflect more heat into the atmosphere，warming the rest of the world.Losing the rainforests may also influence wind and rainfall patterns，potentially causing certain natural disasters all over the world.

In the past hundred years，humans have begun destroying rainforests in search of three major resources(資源)：land for crops，wood for paper and other products，land for raising farm animals.This action affects the environment as a whole.For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests.People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.

There are two main reasons for this.Firstly，when people cut down trees，generally they can only use the land for a year or two.Secondly，cutting large sections of rainforests may provide a good supply of wood right now，but in the long run it actually reduces the world's wood supply.

Rainforests are often called the world's drug store.More than 25% of the medicines we use today come from plants in rainforests.However，fewer than 1%of rainforest plants have been examined for their medical value.It is extremely likely that our best chance to cure diseases lies somewhere in the world's shrinking rainforests.

1.Rainforests can help to adjust the climate because they ______.

A．reflect more heat into the atmosphere

B．reduce the effect of heat from the sun on the earth

C．bring about high rainfall throughout the world

D．rarely cause the temperature to drop lower than 16℃

2.What does the word“this”underlined in the third paragraph refer to?

A．Humans have begun destroying rainforests.

B．People have a strong desire for resources.

C．We will lose much more than we can gain.

D．Much carbon dioxide comes from burning rainforests.

3.It can be inferred from the text that ______.

A．we can get enough resources without rainforests

B．we will grow fewer kinds of crops in the gained land

C．the level of annual rainfall affects wind patterns

D．there is great medicine potential in rainforests

4.What might be the best title for the text?

A．Rainforests and the Environment

B．How to Save Rainforests

C．How to Protect Nature

D．Rainforests and Medical Development

Why Doesn’t Anybody Copy Apple?

Apple’s products are the envy of the world. They have been spectacularly successful and are widely imitated, if not copied. The minute Apple crystallizes a product, everyone knows how to compete．This idea that the basis of competition is set by Apple and then the race is on to climb the path of improvement is unquestionable．When Apple releases a product that defines a category or dramatically changes the structure of an industry, it becomes obvious what needs to be built. But what I wonder is why everyone wants to copy Apple’s products but nobody wants to copy being Apple?

I can think of two reasons. Firstly, Apple is not worth copying because it's not successful; secondly, Apple’s success cannot be copied because it is a magical process．

There is a great deal of evidence for the first hypothesis. The idea of Apple being successful is not something reflected in its stock price．Being valued lower than the average company in the S&P（標準普爾）500 indicates that to whatever degree Apple was successful in the past, it's not seen by the vast majority of observers as successful in the future．Why should one bother copying Apple if it results in being punished with a low valuation? If one works really hard at innovation and then that innovation becomes commoditized（商品化）very quickly, why should one bother?

When innovation practitioners are asked what makes Apple successful, the answers regarding the cause of this success border on the mythical. The climax of this hypothesis is the “chief-sorcerer” theory of success which places one magician, like Steve Jobs, in charge of casting all the right spells（符咒）．

What about Apple’s own opinion of what makes it tick? Tim Cook refers to a great team and integration of hardware, software and services as unique Apple advantages. It’s a better explanation．Integration is something that can take a long time, but it is possible with great effort．A few companies are starting to make moves in that direction, but efforts are half-hearted．There is no “move the Earth” panic to become an integrated company from Samsung, Google or Microsoft．

My own suspicion is that Apple is more aware of what makes it special than it lets out． However, as Tim points out, it’s not a formula．It’s complex, it’s subtle, but it’s not magic．It’s a process that requires a degree of faith and courage．

1.When a new product of Apple comes out, often it ______．

A．ruins an industry dramatically

B．starts a revolution of an industry

C．puts itself in an unbeatable position

D．is soon overtaken by imitated products

2.According to the passage, other companies don’t “copy being Apple” because ______.

A. Apple is not a successful company

B. they have no access to relevant resources

C. It’s hard to find a magician like Steve Jobs

D．being Apple takes more than time and efforts

3.We can infer from Para. 5 that ______．

A．other companies are dedicated to integration

B．Apple itself is fully aware of its unique advantages

C．Apple will hold the leading position in this industry

D．other companies don't have a great team as Apple does

4.What does the author think of Tim Cook's statement?

A．Acceptable． B．Disappointing． C．Unquestionable． D．Convincing．

科目：高中英語 來源：2013-2014學年寧夏高三下學期第二次模擬考試英語試卷（解析版） 題型：閱讀理解

Janelle was running late for work, so she just had time for a quick look at herself in the mirror as she was going out. What she saw there made her stop dead in her tracks.

Being a busy college student just one year removed from her teenage years, she wasn’t exactly obsessive-compulsive(有強迫觀念和行為的) about the neatness of her clothes. But her boss at the restaurant where she works saw things a little differently. He had recently lectured the entire staff on the importance of appearance, and had specifically mentioned the need for servers to wear clean, unwrinkled blouses. As an assistant manager, Janelle felt it was important to set an example for the other employees. But if she stopped to iron the blouse normally, she would be late —and work without delay was an area of even greater concern to her boss.

So she grabbed her iron and plugged it in and set it for low heat. Carefully holding her blouse away from her body, she continued to iron it while she was wearing it. It seemed like a logical answer to an urgent problem.

And it seemed to be working until Janelle tried to iron the collar and accidentally ironed her neck by mistake. Then it suddenly seemed like a really stupid idea and a really painful one as well. It took more time to treat her burn than it would have taken to iron her shirt properly. And she spent a miserable shift dealing with the pain of the burn.

We’ve all been there, haven’t we? For me it was cutting my own hair. For a former roommate it was trying to pull his own wisdom teeth. For another college acquaintance, it was trying to change the oil in his car while the motor was still running.

“There’s a right way and a wrong way of doing things,” Dad used to tell me whenever I’d spoil the look of our yard by trying out a faster, easier and more creative way of pulling weeds or edging the lawn. “If a thing is worth doing,” he said, “it’s worth doing it right.” There’s a reason why certain things are done in certain ways. Those old, boring, predictable ways work.

1.Jenelle found in the mirror that __________.

A．there were stains on her blouse

B．her blouse was wrinkled

C．she wore heavy makeup

D．she put on a wrong blouse

2.It’s learned from Paragraph 2 that______________.

A．Jenelle had no sense of responsibility at work

B．Jenelle failed to set an example for employees in daily work

C．Jenelle didn’t care about the neatness of her clothes at all

D．Jenelle’s boss put doing something on time above appearance

3.What can we infer from the fifth paragraph?

A．We all have done loads of things like Janelle.

B．We are careful enough in daily life.

C．We all have done something creative.

D．We all have tried to iron clothes while we are wearing them.

4.What does the author mainly want to tell readers in the last paragraph ?

A．Be creative. B．A bad beginning makes a bad ending.

C．Stick to old ways. D．Do things right.
