题目内容

【题目】【改编】Can you believe everything that you read? It seems as if every day, some new articles come out about a new discovery about this or that. For example, water is bad for you, or good for you. The answer depends on which scientific study has just come out. People cannot decide which food items are healthy, how pyramids were constructed, and why dinosaurs disappeared. When we look for answers we sometimes can believe persuasive researches and scientists. But how trustworthy are they really? Here are two examples of scientific hoaxes.

As far back as 1726, Johann Beringer was fooled by his fellow scientists into thinking he had made an amazing discovery. The fossils of spiders, lizards, and even birds with the name of God written on them in Hebrew were unlike anything that had been found before. He wrote several papers on them and was famous for those only to have it revealed that they were planted by jealous colleagues to ruin his reputation.

When an early human being was discovered in 1912, scientists at this time were wild with excitement over the meaning it had for the theory of evolution. There were hundreds of papers about this Piltdown man over the next fifty years until it was finally discovered to be a complex hoax. The skull (头骨) of a man had been mixed with the jawbone of an orangutan (猩猩) to make the ape (猿) man.

The next time you read the exciting new findings of a study of the best scientist, do not automatically assume that it is true. Even qualified people can get it wrong. While we certainly should not ignore scientific research, we do need to take it with a grain of salt. Just because it is accepted as the truth today does not mean it will still be trustworthy tomorrow.

【1】What is the main idea of the passage?

A. Everything in the newspaper is doubtful.

B. People are encouraged to suspect everything.

C. Not everything you read is believable.

D. Sometimes scientists may make mistakes.

【2】What does the underlined word hoaxes mean?

A. Truths. B. Tricks. C. Researches. D. Result.

【3】From the second paragraph we can know______.

A. Johann Beringer was envied by his colleagues.

B. Johann Beringer lived in the seventeenth century.

C. Johann Beringer found the Piltdown man.

D. Johann Beringer found he was fooled by others in time.

【4】According to the passage ,the discovery of Piltdown man______.

A. was significant to the theory of evolution.

B. proved orangutan developed from man.

C. didnt prove false until 50 years later.

D. proved that scientists were very careless.

【5】From the last paragraph we can infer the author thinks_____.

A. scientists are unreliable.

B. everyone can make a mistake.

C. we should ignore scientific research.

D. we should treat scientific research reasonably.

【答案】

【1】C

【2】B

【3】A

【4】C

【5】D

【解析】

试题分析: 每天报纸上都会出现一些关于科学新发现的文章,那么这些文章的可信度究竟是多少呢?在文中作者通过几个例子向读者说明:新发现有时候只是一种骗局,或者是一种假象,所以我们对待任何事情都要持有一种怀疑的态度。

【1】C主旨大意题。文章开头提出问题Can you believe everything that you read?然后列举生活中的例子,最后揭示中心话题But how trustworthy are they really? Here are two examples of scientific hoaxes (骗局).由此推断对于我们每天所读到的东西不可能都是对的,选C。

【2】B词义猜测题。上文提到不是所有的文章都是可信的,然后再下文举例说明,由此判断该词意思是骗局,选B。

【3】A细节理解题。根据文章第二段内容可知Johann Beringer受到同事的嫉妒而被愚弄,选A。

【4】 C细节理解题。根据第三段There were hundreds of papers about this Piltdown man over the next fifty years判断选C。

【5】D 推理判断题。根据文章末段内容可知作者重申了主题,认为看待一些科学研究要适度,不要过于相信,故选D。

【题目】Researchers are finding new ways to save snakebite victims.Experts discussed the latest findings during a recent conference.

Scientists in Australia have shown that a chemical called nitric oxide could increase the chances of surviving a poisonous snakebite.The scientists injected rats with a deadly amount of snake venom.Then they rubbed an ointment(软膏)containing nitric oxide on the skin around the injection site.The study found that the rats lived about one-third longer than if nitric oxide had not been used.But the treatment had to be started very quickly.

Dirk van Helden led the research.He says the nitric oxide ointment also showed promise in humans.The study appeared earlier this year in the journal Nature Medicine.Scientists say the findings could help save many lives.A recent study found that poisonous snakes cause as many as ninety-four thousand deaths worldwide each year.But Ulrich Kuch of the Biodiversity and Climate Research Center in Frankfurt,Germany,says that number appears to be low.

Mr Kuch says many deaths could be prohibited if snakebite victims are treated correctly,but they often go to traditional healers or do not seek any help at all.He said,“Sometimes it’s because there is no treatment available—no antivenom(抗蛇毒血清),which is the specific(特殊的)drug to treat snakebites—or health care staff do not know how to treat snakebites,and sometimes its because transportation to get to a health facility is not available or too expensive.

Here is no single antivenom that can be used to treat all snakebites.The antivenom must be specific to the kind of snake that bit the person.In some countries the treatment is costly,while in others there is no such treatment.

1What is this passage mainly about?( )

A.Snakebite deaths around the world.

B.Progress in fighting snakebite deaths.

D.The chances of surviving a poisonous snakebite.

2After being rubbed an ointment containing nitric oxide,the rats .

A.suffered no pain

B.died immediately

C.lived a little longer

D.started feeling uncomfortable

3What does Paragraph 3 suggest?( )

A.The number of deaths caused by snakebites is becoming lower each year.

B.The nitric oxide ointment has saved thousands of people’s lives.

C.It is very important to find an effective way to treat snakebites.

D.The number of deaths caused by snakebites worldwide is low.

4What does the underlined word “prohibited” in Paragraph 4 mean?( )

A. caused. B.considered.

C.examined. D.prevented.

5What is implied in the last paragraph?( )

A.Antivenom can be made very easily.

B.It’s very important to use the correct antivenom to treat snakebite victims.

C.Antivenom is extremely expensive all over the world.

D.A person bitten by a snake will survive as long as there is antivenom.

【题目】My grandma whom we all called Nanny was a solid, first-generation, Italian immigrant. She came to this country with her family on a tiny ship during World War I when she was only 8 years old. During the trip she survived stormy seas,little food, and an attack by a German U-boat. After getting here,her large family worked hard to build a new life in America. They never had much money but were rich in love.

One day, when I was about 5 or 6 years old, my parents and brothers went on a trip. It was just me and Nanny in the house for the weekend. Nanny seemed so happy to be taking care of me all by herself. She made me a special breakfast that first morning. However, all I could do was to complain about how the food was not how Mom always made it. Nanny quietly put down the plate and went into the living room. I followed a minute later and saw that she had tears in her eyes. It was the first time I had ever seen my strong and proud grandmother cry and I was the one who had caused it.

I walked over to Nanny, climbed on her lap, and for the first time in my short life I did something else too. I apologized without being told to and asked Nanny to forgive me. She smiled, rubbed my head, and told me I was a good boy even though I didn't feel like one then.

That memory just like my Nanny's love will stay in my heart forever. It is a sign of both strength and wisdom. Asking for forgiveness helps us to learn, to grow, and to love.
