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 needed to produce a cough was around a third higher than in the placebo group. When they were given codeine they needed only slightly higher levels of capsaicin to cause a cough compared with the placebo.

The researchers said that theobromine worked by keeping down a nerve activity(神经活动), which causes 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?

Imagine looking at something and being able to move it just by using your brain!That is exactly what the new technology called BrainGate can do —with the help of a robotic arm,anyway.

BrainGate is the idea of Professor John Donoghue and his team of researchers at the Brown Institute for Brain Science,USA. BrainGate is attached directly to the brain. First of all,gold wires are put into the part of the brain that controls movement. These are then connected to a small computer chip(芯片) . When the person thinks about different movements,this creates electrical signals,which are picked up by the chip. After this,the signals that are created by the brain are sent back to a computer,which changes the signals into movements. Finally,the computer uses the robotic arm to carry out these movements. BrainGate can already be used to write an e-mail or play computer games,just by brain power.

The technology has already cost millions of dollars to develop and when it is available for use,it will probably cost thousands of dollars per person. There are still many challenges ahead for Donoghue and his team. They are currently planning a mini wireless version,which will allow people to be connected to the computer at all times. Donoghue also dreams of using this technology to help disabled people who can't move their arms or legs. He plans to connect BrainGate directly to their own paralysed limbs(瘫痪的胳膊或腿) .This will mean that the person can control their own body again,without relying on a robotic arm.

This research is attracting the military's (军方的) attention as well. However,it is easy to understand why scientists might be concerned about how thought-controlled machines could be used by the military.

1.What does the underlined word “These” refer to?

A. Movements.　　 B. Thoughts.

C. Brains　　 D. Wires.

2.What is one of BrainGate's disadvantages?

A. It needs improvement.　　 B. It produces few movements.

C. It is too expensive.　　 D. It is difficult to control.

3.How will Donoghue help disabled people?

A. By developing a wireless version.

B. By replacing their limbs with robotic ones.

C. By making BrainGate smaller.

D. By attaching BrainGate to their bad limbs.

4.What does the military think of thought-controlled machines?

A. They could lead to disasters.　　 B. They would face fierce competition.

C. They could be useful.　　 D. They would be in mass production.
