【题目】People who like travelling have their reasons. They believe that travelling can help them expand their field of view, especially in the geographical and historical sense. They also think that touring will give them more chances to enjoy different kinds of food and experience new things that would never be brought by other activities. But those who dislike travelling also have some reasons.

Travelling, in my opinion, does more good than harm. Most importantly, it broadens our mind. We can get in touch with other civilizations (文明), cultures, customs and ideas.

Through history, most people travelled because of necessity (必要性)-not for pleasure. People travelled just in order to remain alive. They searched for food to eat or places to live in. They sometimes ran away from enemies. This is not to say that no one ever travelled just for the fun of it. In ancient times, for example, rich Romans travelled all the way to Greece to take part in the Olympic Games, and festivals. Of course, some people decided to travel just out of curiosity. They wanted to find out what it looked like beyond the horizon (地平线). Also business travel has been going on for centuries. Traders could not only make money but also learn to speak several languages and be introduced to different cultures.

So, travelling does enrich our mind and draw new ideas to us. There is no doubt that we can get much from it.

1According to the passage, in the past most people travelled________.

A. for fun B. for knowledge

C. to get experiences D. to make a living

2How many reasons for travelling are mentioned in Paragraph 3?

A. Three. B. Four.

C. Five. D. Six.

3In the writer’s opinion, travelling can be________.

A. expensive B. funny

C. helpful D. tiring

4What’s the main idea of this passage?

A. Different kinds of travelling.

B. Travelling enriches our mind.

C. Ways to enjoy yourself while travelling.

D. The advantages and disadvantages of travelling.

【题目】Why does cream go bad faster than butter? Some researchers think they have the answer, and it comes down to the structure of the food, not its chemical composition — a finding that could help rid some processed foods of chemical preservatives.

Cream and butter contain pretty much the same substances, so why cream should sour much faster has been a mystery. Both are emulsions — tiny globules(小球体) of one, liquid evenly distributed throughout another. The difference lies in what's in the globules and what's in the surrounding liquid, says Brocklehurst, who led the investigation.

In cream, fatty globules drift about in a sea of water. In butter, globules of a watery solution are locked away in a sea of fat. The bacteria which make the food go bad prefer to live in the watery regions of the mixture. “This means that in cream, the bacteria are free to grow throughout the mixture,” he says.

When the situation is reversed, the bacteria are locked away in compartments(分隔间) buried deep in the sea of fat. Trapped in this way, individual colonies cannot spread and rapidly run out of nutrients(养料). They also slowly poison themselves with their waste products: “In butter, you get a self-limiting system which stops the bacteria growing,” says Brocklehurst.

The researchers are already working with food companies keen to see if their products can be made resistant to bacterial attack through alterations to the food's structure. Brocklehurst believes it will be possible to make the emulsions used in salad cream, for instance, more like that in butter. The key will be to do this while keeping the salad cream liquid and not turning it into a solid lump.

1The significance of Brocklehurst's research is that ________.

A. it suggested a way to keep some foods fresh without preservatives

B. it discovered tiny globules in both cream and butter

C. it revealed the secret of how bacteria multiply in cream and butter

D. it found that cream and butter share the same chemical composition

2According to the researchers, cream sours faster than butter because bacteria ________.

A. are more evenly distributed in cream

B. multiply more easily in cream than in butter

C. live on less fat in cream than in butter

D. produce less waste in cream than in butter

3The underlined word “colonies” (Line 2, Para 4) refers to ________.

A. tiny globules

B. watery regions

C. bacteria communities

D. little compartments
