There are two types of twins; identical and non-identical twins. Identical twins are formed from a single egg in mother’s body which divides to from two separate babies. Identical twins look the same, and are often dressed by their parents in clothes of the same colors. It is often difficult to tell identical twins from each other, even when they are standing side by side. Non-identical twins come into being when the mother produces two separated eggs a the same time, both of which grow to form babies. In this case the twins look like normal brothers and sisters and are easy to tell one from the other.
In the 1970s and 1980s a scientist did some research into twins. He invited many pairs of identical twins to university and asked them to take part in a week of tests. He was particularly interested in adopted (收养) twins who had been separated at birth. He would give the twins different kinds of tests to study their speed of thinking, their speech, their memory, the ways they saw and heard different things, and so on. Time and time again he found separated twins who preferred clothes of the same color, used the same kind of shaving soap, wore the same shaped square glasses and the same colored socks.
There is a third type of twins, but it is a very unusual one. Twins which are joined together at birth are known in western countries as Siamese twins.It is difficult to tell identical twins apart because _______.
| A．they are dressed in the same clothes | B．they are dressed in the same color |
| C．they are very alike | D．they are standing side by side |
If the twins are easy to tell from each other, they are ______.
| A．very probably non-identical twins | B．surely identical twins |
| C．surely identical twins | D．always a brother and a sister |
Which of the following is NOT true according to this passage?
| A．In the 1970s and 1980s a scientist did some research into the two main types of twins. |
| B．In the week of tests, he tested their speed of thinking, their speech, their memory and some other things. |
| C．There were twins who had been separated from each other as soon as they were born. |
| D．Very often, separated twins were found to choose things of the same kind, the same shape and the same color. |
This passage mainly tells us _______.
| A．the main types of twins | B．what has been found out about twins |
| C．how twins are formed | D．how a scientist studied twins |
Astronauts’ meals have come a long way from the free-dried powders and semi-liquid pastes of decades ago，now US scientists want to grow vegetables in mini-greenhouses on the moon．
Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables．Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers——and eventually food—on the moon.
This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminium frame(三角铝框架)．It is designed to safely land a laboratory plant on the lunar surface，and protect it while it grows．
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $20 million to any entrant(参加者) who can launch，land and operate a rover（漫游）on the lunar surface.
Paragon officials say future testing of the“Lunar Oasis”will be driven by Odyssey’s flight schedule，which will not happen until 2012 at the earliest．
When it does lift off the greehouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage．Because Brassica goes from seed to flower in just 14 days，it can complete its life cycle in a single lunar night
“Colonizing the Moon or Mars seems so far away，but it is important that we do this research now，” Paragon president Jane Poynter said．
“It takes a long time to get a lot of research，and to get integrated，reliable efficient systems before colonists move in．”she said．
1. The article is written mainly to _________.
A. predict the astronauts’meals in the future

A. astronauts ean grow flowers in space at present
B. Paragon and NASA will carry out the test separately
C. Lunar Oasis is a series of experiments carried out in space
D. the earliest testing of the Lunar Oasis may be in 2012
3. The underlined word “colonists”in the last paragraph probably has the meaning of _______.
A. plants B. wild beasts C. human beings D. scientists
4. The seeds of Brassica will be contained in the greenhouse mainly because _______.
A. their life cycle is much shorter
B. they are more nutritious than other food
C. they are related to Brussels sporouts and cabbage
D. they are very delicious

Depression(抑郁症)is a serious problem today. Depression causes workers to be unproductive，causing companies and countries to lose billions of dollars. One expert says that depression is like cancer because it is “widespread, costly and deadly”. Depression hits one person in five around the world.
Although people have believed depression to be a problem among the rich and educated, studies show that depression is a problem among everyone．Over any six-month period, between five to seven percent of the world’s population will be suffering from a serious depression．
Suicide(自杀) rates among people suffering from the disease in its extreme, or clinical form were 80 percent higher than in the population at large．and suffers were four times more likely to have heart attacks．People who suffer from depression often have problems sleeping，getting up on time，and doing work productively.
Depression，which researchers agree has its origin in the genes(基因)，brings loss of confidence and ability to concentrate—making it impossible for employees and managers to work efficiently．
Depression is made more serious in China by Chinese’s inability to face it．Many people believe that depressed people are either weak or lazy．Besides，there is no good treatment，with few specialists available．
“Most patients in China just don’t get h
elp，”a Chinese doctor says．“In my hospital，I have to see 30 or 40 patients in a morning，and just have time to say ‘Hello，how do you feel? ’ ”
In Western countries，people are not afraid to admit that they have depression，but most do not tell it to their boss，because they fear that their boss would fire them．
“In my experience，aging bosses are the most willing to admit they have it, because they feel the most secure about themselves．”an American doctor says.
Hopefully，in the near future，people around the world will be able to admit that they have depression so that they can get the right treatment.

The trend in everyday conversation is to use grandiose(夸大的) words. “Outstanding”is new “good,” “amazing” is the new “OK,” and “huge” is the new “big”.
I was in a restaurant in Washington D．C．last weekend and every question I asked was answered with exaggeration．
Me：How is the salmon?
Sever：Fantastic!
Me：Does it come with rice?
Sever：Absolutely!
Would a “good” and a “Yes” have been enough? Of course!
My father is an average-sized man．He hasn’t gained weight or height for the past 30 years. Therefore, his size remains the same．However，in the same amount of time，his T-shirt size has gone from small to medium to large to extra large．
The reason for the exaggerated word is clear：we are bored with our lives．We want the next—next thing now．Immediately!
And we also want others to think that we still care，that we can still be delighted，that we know that everything is just great．Even when deep inside we know it can’t be．Everything can’t be great．
I’m not a scientist，so many methods of proof leave little to be desired，or a lot to be desired，or an immensity(无限)．
Listen to the voices around you．Listen to your own voices．There is nothing on the radio that is good or bad，weather is either beautiful or horrible．
Listen，the next time when someone asks you something and you agree，because when you could simply say “yes”, instead you will say “absolutely’’or “without doubt”or “Oh，yeah，unquestionably---absolutely without doubt. ”
Have people forgotten what it is like to be OK? Simply OK with what they have and who they are?If everything is outstanding，if everything is the most amazing thing ever，is anything ever amazing at all?

第三部分：阅读理解（共20小题；每小题2分，满分40分）
阅读下面短文，从每题所给的四个选项（A、B、C、D）中，选出最佳选项，并在答题卡上将该项涂黑.
Many children first learn the value of money by receiving an allowance (pocket money). The purpose is to let children learn from experiences at an age when financial mistakes are not very costly．
The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration．Some children get a weekly allowance．Others get a monthly allowance．
In any case, parents should make clear what，if anything, the child is expected to pay for with the money．At first, young children may spend all of their allowance soon after they receive it. If they do this，they will learn the hard way that spending must be done within a budget．Parents are usually advised not to offer more money until the next allowance．
The object is to show young people that a budget demands a choice between spending and saving．Older children may be responsible enough to save money for larger costs，like clothing or electronics．Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home．These jobs are a normal part of family life．
Paying children to do extra work around the house，however，can be useful．It can even provide an understanding of how a business works．
Allowances give children a chance to experience the three things they can do with money．They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want．Or they can save it.
Saving helps children understand that costly goals require sacrifice．You have to cut costs and plan for the future．Requiring children to save part of their allowances can also open the door to future saving and investing．Many banks offer services to help children and teenagers learn about personal finance.
A saving account is an excellent way to learn about the power of compound interest.
Compouding works by paying interest on interest．So，for example，one dollar invested at two percent interest for two years will earn two cents in the first year. The second years，the money will earn two percent of one dollar and two cents，and so on. That may not seem like a lot．But over time it adds up．
