“Global warming could make humans shorter,” warn scientists who claim to have found evidence that it caused the world's first horses to shrink(收缩) nearly 50 million years ago. In fact, a team from the universities of Florida and Nebraska says it has found a link between the Earth heating up and the size of mammals – horses, in this case.
The scientists used fossils to follow the evolution of horses from their earliest appearance 56 million years ago. As temperature went up,their size went down, and vice versa(反之亦然);“ At one point they were as small as a house cat,” said Dr Jonathan Bloch, curator(博物馆长) of the Florida Museum of Natural History, which was quoted by the "Daily Mail" as saying.
The scientists say that the current warming could have the same effect on mammals and could even make humans smaller."Horses started out small, about the size of a small dog . What's surprising is that after they first appeared, they then became even smaller and then dramatically increased in size, and that exactly corresponds to the global warming event, followed by cooling”
"It had been known that mammals were small during that time and that it was warm, but we hadn't realized that temperature specifically was driving the evolution of body size," Dr Bloch said in the "Science" journal.
How did scientists find out the horses’ earliest appearance millions of years ago?

A.searching the data on the net
B.sorting through the pictures of ancient times
C.using fossils to follow the evolution
D.analyzing the related images

What can we infer form the passage?

A.As temperatures went up, horses dramatically increased in size
B.The temperature has no effect on mammals’ evolution
C.As temperatures went up, horses’ size went down
D.In history, it used to be warm at early times , followed by a certain period of sharply cooling down.

Which is the most closest meaning to the underlined words most probably mean _______.

A.react to B. be contradictory to
C.be consistent with D. differ from

What is the best title of the passage?

A.Global warming is to disappear
B.The temperature on earth is to decrease
C.Global warming makes human shorter

Jean is a bright young woman who comes from a rich and famous family. She goes to a good university and has everything that money can buy. Well, almost everything. The problem is that Jean’s family are so busy that they can hardly find time to be with her. In fact, Jean is quite lonely. So Jean spends a lot of time on her QQ. She likes being anonymous, talking to people who do not know about her famous family and her rich life. She uses the name Linda on QQ and has made a lot of friends who she keeps in touch with quite often.
Last year Jean made a very special friend on QQ. His name was David and lived in San Francisco. David was full of stories and jokes. He and Jean had a common interest in rock music and modern dance. So it always took them hours to talk happily on QQ and sometimes they even forgot their time. Of course, they wanted to know more about each other. David sent a picture of himself: He was a tall , good looking young man with big , happy smile. As time went by, they became good friends and often sent cards and small things to each other.
When Jean’s father told her that he was going on a business trip to San Francisco, she asked him to let her go with him so that she could give David a surprise for his birthday. She would take him the latest DVD of their favorite rock singer. But when she knocked on David’s door in San Francisco, she found that her special friend was a twelve-year-old boy named Jim!

You might say that Barack Obama was elected President of the US because he knows how to give a good speech. In 2004, the little-known Obama gave a speech at the Democratic national Convention(民主党全国会议). It was a great speech---poetic, and inspiring. The people who heard it would remember it for a long time.
Since 2004, Obama has written and delivered thousands of speeches. These are usually praised for two reasons: he treats the audiences like intelligent adults, and he is able to express difficult ideas in a straightforward, natural way.
Before becoming President, Obama was a lawyer, a college professor, and a successful writer---his two memoirs have become best-sellers. The skills he needed to succeed in his previous jobs have also contributed to his success as a speechmaker.
As a lawyer, Obama learned how to make strong, convincing arguments. As a professor, he learned how to explain complex subjects in ways that helped students understand without boring them. As a writer, he learned how to use language to have a powerful influence on his audience.
Secret weapons of Obama
Writing team: Obama has a team of people who write his speeches. The writers chat with Obama for hours about what he wants to say. They listen to recordings of past presidential addresses and seek advice from advisers. Obama usually edits and rewrites the drafts several times.
Make fun of the guests: Obama starts his speech by gently making fun of his guests. His opening lines attract the audiences’ attention while giving them an opportunity to relax and laugh at themselves and each other.
Making fun of himself: Obama laughs at his past mistakes and is never afraid of showing them to the public.
Obama delivers speeches to audiences large and small. He can make his audiences laugh or cry. His speeches are always thoughtful, well written, and just right for each occasion.
.. The third and fourth paragraphs mainly talk about _____.

A.why Obama’s speeches are praised B.how Obama acquired his speaking ability C.what subjects Obama’s speeches about D.Obama’s success as a writer and a lawyer

A group of students in Japan have created a realistic robot baby to motivate young people to start planning a family so as to increase the country’s birth rate. The automated (自动化的)doll developed at the University of Tsukuba, called Yotara, laughs and “wakes up” when a rattle is shaken.
He can become angry and sleep like a real baby and he smiles when his stomach is pressed. The robot can also sneeze and have a runny nose, thanks to a heated water pump system. The students of the Graduate school of Comprehensive Human Science at the university created the robot last year with touch sensors. A projector sends the facial features onto a warm silicon balloon which makes up Yotara’s face. The robot’s facial expression and body movements change according to pressure applied to different parts of its body.
The information collected through touch sensors(传感器)under the silicon skin is processed by a special programme. It then changes the baby’s expression projected onto the balloon-face from behind. There is a hat on the robot’s head and a colorful blanket covering the robot’s limbs which simulate wiggling(摆动) with the help of a geared motor. “We wanted to create a new type of robot that is soft, cuddly and cute,” said project leader Hiroki Kunimura.
“We’d like people to experience the innocent, joyful expressions typical of small babies. Through this experience, it would be great if some people started feeling that they wanted to have their own baby, if they started feeling that work is not everything.”
Japan’s birth rate is among the lowest in the developed world at 1.37%, compared to 2.12% in the United States and l.84%in Britain. Japan is facing serious economic consequences with over a quarter of its citizens expected to be aged over 65 by 20l5.The population is expected to reduce by a third within 50 years if the birth rate does not increase.
. What is the students’ purpose of creating such a baby?

A.To help old people who live alone. B.To give small children some pleasure
C.To comfort lonely young people. D.To increase the population of Japan.

What’s the new type of robot like in Hiroki Kunimura’s mind?

A.It can do everything for humans. B.It is clever, humorous and loyal.
C.It is gentle, lovely and smart. D.It makes humans unhappy.

. What can we learn from the passage?

A.Many young people in Japan don’t want to get married.
B.There may be a lack of workers in Japan in the future.
C.The lifespan(寿命)of Japanese people will decrease in the future.
D.The birth rate in Japan will start to increase slowly soon.
