      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 forcrops, 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 l% 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. bring about high rainfall throughout the world
C. rarely cause the temperature to drop lower than 16℃
D. reduce the effect of heat from the sun on the earth
2. What  does  the  word "this" underlined in the third paragraph refer to?  
A. We will lose much more than we can gain.
B. Humans have begun destroying rainforests.
C. People have a strong desire for resources.
D. Much carbon dioxide comes from buming rainforests.
3. It can be inferred from the text that____________.   
A. we can get enough resources without rainforests
B. there is great medicine potential in rainforests
C. we will grow fewer kinds of crops in the gained land
D. the level of annual rainfall affects wind patterns
4. What might be the best title for the text?  
A. How to Save Rainforests
B. How to Protect Nature
C. Rainforests and the Environment
D. Rainforests and Medical Development

This week in our Foreign Student Series，we talk about getting an American education online．A student named Hendra has written to us from Indonesia asking about a good online university．Finding the right online program requires research．Talking to advisers and recruiters（招募者）can help．Keep in mind，though，that they might have a financial interest to direct you to certain programs．

Also，consider the level of interaction that an online program offers．You might never meet the teacher or other students in person．

A
Shopping in the United States changes a lot．About ninety years ago most people shopped in small stores that were owned by one person or a family．Women went from the bakery to the butcher's to the grocer and on to the fruit and vegetable seller in order to get their food for the week．
Then about sixty years ago, supermarkets were born．In a supermarket, people could get all the different kinds of food they needed without going to different stores．
The next big change in shopping in the United States was the shopping mall．A shopping mall is a group of stores under one roof．Because malls allowed people to shop without worrying about the weather, they soon became very popular．The mall became a place for people to socialize in addition to shopping．If you walk through a mall, you will see older people sitting, chatting and drinking coffee．Malls are places for teenagers to hang out．Many teens will often just "go to the mall" and spend time with their friends．
The recent change in American shopping was the superstore．Large chain stores such as Wal-Mart, Office Depot and Toys "R" Us have been built all across the United States．Because they are so large, they can buy goods at a great discount and sell them much cheaper than smaller stores．
Sometimes, when they are built near small towns, many of the small town stores have to close．They just cannot compete with their giant neighbors．
And now, online shopping is becoming more and more popular all over the States．People are too busy to go to the physical stores, so they go shopping over the Internet．Online shopping has lots of advantages．For instance, online stores are usually available 24 hours a day．Searching or browsing online shops can be faster than browsing the physical stores．While, online shopping also has its disadvantages．People are at higher risk of being cheated on the part of the merchant than in a physical store．And privacy of personal information may be let out．
56．Which of the following shows the right order of shopping development in the United States?
①small stores  ②superstores   ③shopping malls    ④shopping online
⑤supermarkets
A．①②③④⑤             B．①⑤②③④
C．①⑤③②④          D．②③④①⑤
57．Which is the place for people to spend time with others according to the passage?
A．Shopping malls．           B．Small stores．      
C．Supermarkets．          D．Superstores．
58．Why can the superstores sell products at much lower prices?
A．Because they are built near small towns．
B．Because they are across the United States．
C．Because they sell all kinds of products people need．
D．Because they can buy goods at a reduction in the price．
59．What's the disadvantage of online shopping according to the passage?
A．Wasting time．         B．Leaking personal information．
C．Fixed prices．        D．No chance to do physical activities

三節(jié)．閱讀理解（40%）

閱讀理解下面的短文，然后按要求答題。

I was born in New York, but I grew up in San Francisco. I began to live in London 25 years ago. If I am asked now where I want to live forever, I would say London. But I will always be American.

San Francisco, like London, has many parks. Every day my sisters and I were taken to play in the parks as children. I didn't go to school. I only had three hours of formal education when I was five. I was sent to school in the morning but came home at noon on the first day. I said I didn't enjoy it and hadn't learned anything. My parents thought that school was unsuitable for me. They agreed with me, so I never went back to school.

Then my mother taught me and my two sisters at home, in the way of an English lady who had good education. We learned languages and reading more than sciences and maths. Sometimes she taught us herself, but we also had other teachers. They asked us to take lessons every day. About once a week we walked to Golden Gate Park. While we were walking, my mother taught me to read music. One day I noticed a little toy train in the window of a shop and I remember now how I'd like to have it. I couldn't say "r" when I was small. My mother said if I could say an "r" well, I would have the toy train. I practiced and practiced. Then one morning I woke everybody up with my "r"s. I got the toy train. I usually get the things I want in life — but I work hard for them.

1 The writer ___ .

A. was born in San Francisco      B. likes living in London

C. is living in New York now      D. doesn't like America

2. The writer didn't go to school in America because ___ .

A. his mother wanted him to go to school in English

B. his parents didn't think formal education was right for him

C. his mother wanted him to play outdoors in the parks

3. Which of the following is TRUE?

A. The writer was taught by his mother and other teachers.

B. The writer had no education at all.

C. The writer didn't have lessons every day.

D. The writer walked to the park to learn languages once a week.

4. The writer got the little toy train at last because ___ .

B. he tried his best to read music

C. he wanted it very much

D. his mother was pleased with his progress

科目：高中英語(yǔ) 來(lái)源：山東省同步題 題型：閱讀理解

閱讀理解
    A university math tutor has discovered the science behind "singledom",finding that our chances of finding
the perfect partner are just 1 in 285,000.Peter Backus,a tutor at the University of Warwick,published his
"Why I Don't Have a Girlfriend" paper after a threeyear love drought.
    His unconventional study uses a famous math formula called The Drake Equation (德雷克等式),which
was first used to estimate the existence of extraterrestrial (地球以外) life.
    The results don't look promising for British singles.30yearold Mr Backus found that out of the 30 million
women in the UK,only 26 would be suitable girlfriends for him.
    The dull equation takes into account the number of  women aged  24  to 34, living in his home city of
London,and who are single,meaning his chances of meeting his dream woman on a night out are slim.
    The economics expert said: " There are  26 women in London with whom I  might have a wonderful
relationship.So, on a given night out in London there is a 0.0000034%  chance of meeting one of  these
special people.That's a 1 in 285,000 chance,so it's not great."
    The puzzling Drake equation reads: N＝R* x Fp x Ne x Fi x Fc x L,and helped pioneering scientist
Professor Drake to predict that there could be 10,000 civilizations in our galaxy.
    Mr Backus simply replaced the original equation with his own criteria for a dream date,which included
the percentage of women likely to find him attractive,and the number of girls aged 24～34 in London.He
said:"The research may sound depressing to people looking for love,but the_good_news_for_singles is,it's
probably not your fault!"
1．Mr Backus' discovery in this passage is mainly concerned about________.
A．whether there exists life out of our planet
B．the possibility of his being able to find love
C．how to get rid of singledom
D．what math can do to serve our daily life
2．What does Mr Backus think of the result of his research?
A．Optimistic.  
B．Depressing.  
C．Unrealistic.  
D．Exciting.
3．What can we learn from the first paragraph?
A．Mr Backus' major research field is "singledom"．
B．Mr Backus found a girlfriend three years ago.
C．Mr Backus' new thesis will surely be well received.
D．Mr Backus has been searching for love for long.
4．By "the good news for singles" in the last sentence,Mr Backus probably mean________.
A．you don't have to blame yourself for remaining single
B．maybe the discovery is not reliable at all
C．the result was based on his own criteria
D．there might be more dream date out of London
5．Which of the following statements is true?
A．This passage could be published in a scientific magazine.
B．The passage intends to prove there are other civilizations.
C．The writer doesn't really understand the Drake equation.
D．Most women in London are not suitable for university teachers.
