Something in chocolate could be used to stop coughs and lead to more effective medicines, say UK researchers.

Their study found that theobromine, found in cocoa, was nearly a third more effective in stopping coughs than codeine, which was considered the best cough medicine at present.

The Imperial College London researchers who published their results online said the discovery could lead to more effective cough treatment. “While coughing is not necessarily harmful(有害的) it can have a major effect on the quality of life, and this discovery could be a huge step forward in treating this problem,” said Professor Peter Barnes.

Ten healthy volunteers(志愿者) were given theobromine, codeine or placebo, a pill that contains no medicine, during the experiment. Neither the volunteers nor the researchers knew who received which pill. The researchers then measured levels of capsaicin, which is used in research to cause coughing and as a sign of how well the medicine are stopping coughs.

The team found that, when the volunteers were given theobromine, the capsaicin need to produce a cough was around a third higher than in the placebo group. When they were given codeine they need only slightly higher levers of capsaicin to cause a cough compared with the placebo.

The researchers said that theobromine worked by keeping down a verve activity(神經(jīng)活動(dòng)), which cause coughing. They also found that unlike some standard cough treatments, theobromine caused no side effects such as sleepiness.

1.According to Professor Barnes, theobromine ______.

A. cannot be as effective as codeine

B. can be harmful to people’s health

C. cannot be separated from chocolate

D. can be a more effective cure for coughs

2.What was used in the experiment to cause coughing?

A. Theobromine. B. Codeine. C. Capsaicin. D. Placebo.

3.We learn from the text that volunteers in the experiment _____.

A. were patients with bad coughs

B. were divided into the three groups

C. received standard treatments

D. suffered little side effects

4.Which of the following would be the best title for the text?

A. Codeine: A New Medicine B. Chocolate May Cure Coughs

C. Cough Treatment: A Hard Case D. Theobromine Can Cause Coughs

科目：高中英語(yǔ) 來(lái)源：2014年外研版高中英語(yǔ)選修十一模塊3練習(xí)卷（解析版） 題型：閱讀理解

Grown?ups are often surprised by how well they remember something they learned as children but have never practiced ever since. A man who has not had a chance to go swimming for years can still swim as well as ever when he gets back in the water. He can get on a bicycle after many years and still ride away. He can play catch and hit a ball as well as his son. A mother who has not thought about the words for years can teach her daughter the poem that begins “Twinkle, twinkle, little star” or remember the story of Cinderella or Goldilocks and the Three Bears.

One explanation is the law of overlearning, which can be stated as follows: Once we have learned something, additional learning trials increase the length of time we will remember it.

In childhood we usually continue to practice such skills as swimming, bicycle riding, and playing baseball long after we have learned them. We continue to listen to and remind ourselves of words such as “Twinkle, twinkle, little star” and childhood tales such as Cinderella and Goldilocks. We not only learn but overlearn.

The multiplication tables (乘法口訣表) are an exception to the general rule that we forget rather quickly the things that we learn in school, because they are another of the things we overlearn in childhood.

The law of overlearning explains why cramming (突擊學(xué)習(xí)) for an examination, though it may result in a passing grade, is not a satisfactory way to learn a college course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little overlearning, on the other hand, is really necessary for one's future development.

1.What is the main idea of Paragraph 1?

A．People remember well what they learned in childhood.

B．Children have a better memory than grown?ups.

C．Poem reading is a good way to learn words.

D．Stories for children are easy to remember.

2.The author explains the law of overlearning by________.

A．presenting research findings

B．setting down general rules

C．making a comparison

D．using examples

3.According to the author, being able to use multiplication tables is ________.

A．a(chǎn) result of overlearning

B．a(chǎn) special case of cramming

C．a(chǎn) skill to deal with math problems

D．a(chǎn) basic step towards advanced studies

4.What is the author's opinion on cramming?

A．It leads to failure in college exams.

B．It's helpful only in a limited way.

C．It's possible to result in poor memory.

D．It increases students' learning interest.
