(1) Mr. Brown (the motorist) (驾车人)

At about 9:20 p.m. on October 14th, I was driving along Market road in the direction of Midwick. I wanted to go to Sturham to collect my wife, who had been visiting some friends. I prepared to turn into Sturham Road, which was on my right. In the distance, I saw the lights of a car moving towards me but it was a long way from me. I put out my hand to show that I was going to turn right. Then I started to turn slowly towards Sturham Road. Suddenly there was a loud noise on the passenger’s (near) side of the cars. I stopped the car and got out. A motor-cycle (摩托车) had hit my car. The motor-cyclist had been thrown over the car. He was injured, so I ran to a shop to phone for help.

(2) Mr. Smith (the injured motor-cyclist)

On the evening of October 14th, I was going home along Market Road towards Newtown. I was riding my motor-cycle. I was going slowly because some of the street lights were out and the road was wet and slippery. Just before Sturham Road, a car suddenly drove right across my path. The driver did not flash his light to give a warning. I would not turn in time, so I hit the side of the car. When I woke up, I was lying in a hospital in Market Road.

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(神经活动), 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

 

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 (乘法口诀表) 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 (突击学习) 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 result of overlearning

B.a special case of cramming

C.a skill to deal with math problems

D.a 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.

 

A volcanic eruption in Iceland has sent ash across northern Europe. Airlines have stopped or changed the flights across the Atlantic Ocean, leaving hundreds of passengers stuck in airports.

Grirmsvom is one of the largest and most active volcanoes in Europe. What makes Grimsvom different is that it lies under a huge glacier(冰川) of ice up to 12 maters thick. The hot volcano heats up the ice above it, which then forms a layer(层)of water between the glacier and the volcano This layer of water puts pressure on the volcano, keeping it stable, As the water flows out from under the glacier, the pressure lifts. The lava(岩浆) from the volcano then comes up to the surface. This is exactly what happened today.

Now, airlines have to make changes to their flights so as not to fly through the clouds of volcanic ash. According to KLM. one of Europe’s biggest airlines, airplanes cannot go under the cloud or over it. Going through the cloud can result in ash getting stuck in the airplane’s engines, causing damage to the plane.

The eruption has also caused problems for animals in Iceland. The volcano left ash and sharp. Glass-like rocks all over the countryside. Farmers are keeping their animals inside to stop them from eating ash- covered grass to the sharp object.

B. The low water temperature

C. The thick glacier

3.Which of the following is the result of the volcanic eruption?

A. People stop traveling in Europe

B. Airlines suffer from the loss of planes

C. It becomes dangerous for animals to eat outside

D. Farmers have lost many of their animals

4.This text is most probably taken from_
