题目内容

【题目】Jennifer Fish, a weather forecaster may soon be replaced by something truly fishier---the shark.

Research by a British biology student suggests that sharks could be used to predict storms.

Laura Smith, 24, is close to completing her study on shark’s ability to sense pressure.

If her studies prove the theory, scientists may be able to monitor the behaviour of sharks to predict bad weather.

Miss Smith had previously studied the behaviour of lemon sharks in the Bahamas.

She then used their close relatives, lesser spotted dogfish (猫鲨), for further research at Aberdeen University.

Her work---thought to be the first of its kind to test the pressure theory---resulted from the observation that juvenile blacktip sharks off Florida moved into deeper water ahead of a violent storm in 2001.

Miss Smith said: “I’ve always been crazy about traveling and diving and this led me to an interest in sharks.”

“I was delighted to have been able to research in the area for my degree. I know there’s so much more we need to understand---but it certainly opens the way to more research.”

It has been discovered that a shark senses pressure using hair cells in its balance system.

At the Bimini Shark Lab in the Bahamas, Miss Smith fixed hi-tech sensors to sharks to record pressure and temperature, while also tracking them using GPS (Global Positioning System) technology.

In Aberdeen, she was able to study the effects of tidal (潮汐的) and temperature changes on dogfish---none of which were harmed. She also used a special lab which can mimic (模拟) oceanic pressure changes caused by weather fronts.

She is due to complete her study and graduate later this year. She says she will be looking for a job which will give her the chance to enrich her experience of shark research.

【1】The passage is most probably taken from .

A. a short-story collection B. a personal diary

C. a research paper D. a popular science magazine

【2】What do we learn from the first four paragraphs of the passage?

【答案】Research by a British biology student suggests that sharks could be used to predict storms.，C选项A new research effort in predicting storms.

【解析】本文为科普类文章，介绍了一位英国生物系学生对于鲨鱼来预测暴风雨的研究。

【1】推理判断题。本题适宜用排除法。根据文章内容来看这是一篇科普文，A、B可删除，再从文章的语言来判断，并未出现大量的专业术语，可删除C “a research paper” （科研论文）。故选D。

【2】推理判断题。由第一段和第四段可知，前四段所要表达的含义为If her studies prove the theory, scientists may be able to monitor the behavior of Sharks to predict bad weather.（科学家们可以通过监视鲨鱼的行为来预测不好的天气”。故选C。

【3】细节理解题。由文章倒数第三段可知，Miss Smith 在鲨鱼身上安装高科技感应器来记录 pressure(压力)和temperature(温度)，故选A，

【4】主旨大意题。文章的主旨句为第二段Research by a British biology student suggests that sharks could be used to predict storms.，全文围绕着鲨鱼可能被用来预测天气的研究展开。故选C。

【题目】阅读下面短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项。
C
Women are friendly. But men are more competitive. Why? Researchers have found it's all down to the hormone oxytocin (荷尔蒙催生素). Although known as the love hormone, it affects the sexes differently.
“Women tend to be social in their behavior. They often share with others. But men tend to be competitive. They are trying to improve their social status,” said Professor Ryan.
Generally, people believe that the hormone oxytocin is let out in our body in various social situations and our body creates a large amount of it during positive social interactions (互动) such as falling in love or giving birth.
But in a former experiment Professor Ryan found that the hormone is also let out in our body during negative social interactions such as envy.
Further researches showed that in men the hormone oxytocin improves the ability to recognize competitive relationships, but in women it raises the ability to recognize friendship.
Professor Ryan's recent experiment used 62 men and women aged 20 to 37.
Half of the participants（参与者）received oxytocin. The other half received placebo (安慰剂).
After a week, the two groups switched with participants. They went through the same procedure with the other material.
Following each treatment, they were shown some video pictures with different social interactions. Then they were asked to analyze the relationships by answering some questions. The questions were about telling friendship from competition. And their answers should be based on gestures, body language and facial expressions.
The results indicated that, after treatment with oxytocin, men's ability to correctly recognize competitive relationships improved, but in women it was the ability to correctly recognize friendship that got better.
Professor Ryan thus concluded: “Our experiment proves that the hormone oxytocin can raise people's abilities to better distinguish many kinds of social interactions. And the behavior differences between men and women are caused by biological factors (因素) that are mainly hormonal.”
（1）What causes men and women to behave differently according to the text?
A.Placebo.
B.Oxytocin.
C.The gesture.
D.The social status.
（2）What can we learn from Professor Ryan's former experiment?
A.Oxytocin affects our behavior in a different way.
B.Our body lets out oxytocin when we are deep in love.
C.Our body produces oxytocin when we feel unhappy about others' success.
D.Oxytocin improves our abilities to understand people's behavior differences.
（3）Why did Professor Ryan conduct the recent experiment?
A.To test the effect of oxytocin on the ability to recognize social interactions.
B.To know the differences between friendship and competition.
C.To know people's different abilities to answer questions.
D.To test people's understanding of body language.
（4）The underlined word “distinguish” has the closest meaning to ______.
A.accept
B.discover
C.differ
D.explore
（5）The author develops the text by______.
A.explaining people’s behaviors
B.describing his own experiences
C.distinguishing sexual differences
D.discussing research experiments

【题目】根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

For generations, people have dreamed of traveling to Mars to explore Earth’s closest planetary neighbor. The American Space Agency, NASA, and other space agencies have announced plans to send people to the Red Planet.【1】.

In the United States, some volunteers are learning how people will react to months of separation from other humans on a Mars base.【2】 But actually, they are living in Hawaii. The project is called HI-SEAS. NASA has provided financial support for the work.

Six people are living on a make-believe Mars Base. They are isolated high on top of Mauna Loa, a volcanic mountain on the Big Island of Hawaii, whose environment is as close to Mars as we can find on Earth. 【3】 When measured from its base, deep in the ocean, Mauna Loa is the second largest mountain in our solar system. Because it is so high, the land is not warm or rich with plants, like the rest of Hawaii. Visually, it is very similar to what you see on Mars. They can walk across red lava rock from the volcano and see the wonderful volcanic material. There is really no visible plant life or animal life.

The six member HI-SEAS crew is mostly self-sufficient. They take care of themselves.【4】

But the individuals bringing those supplies cannot communicate with volunteers inside the base. The current crew has been living in the base since October, and will stay until June. Crew members communicate with the outside world through e-mail and blogs. They also produce videos on the YouTube website.【5】

Food and supplies are brought to them.

A. But such a manned mission is years away.

B. Mars has the largest volcanic mountain in the solar system.

C. They are spending eight months in an area that looks much like the surface of Mars.

D. Mauna Loa is 2,500 meters above sea level.

E. Conditions on the surface of Mars are closer to the conditions on Earth.

F. For now, on a mountaintop in Hawaii, volunteers are getting a taste of life on a future Mars base.

G. Food and supplies are brought to them.
