an ostrich and discovered, to his great surprise, that the big bird had swallowed a bunch of diamonds. How could such a strange thing happen?Like many other birds, the ostrich swallows small stones that stay inside its “gizzard”. The gizzard is a bird’s second stomach. It is where the food is ground up. The small stones help to grind up the food so it can be digested. The small stones do the chewing because birds don’t have teeth. In that case of the ostrich with the diamonds, the bird simply had expensive taste in rocks. It used the diamonds to digest its dinner.
Diamonds and stones aren’t all that an ostrich will swallow. If there are no stones around, it will eat just about anything. Sadly for ostriches in zoos, this can be a fatal h
abit. The tendency to swallow anything it sees has caused the death of many an ostrich. Cruel or careless people often throw things into the bird’s living space. They throw keys, coins, and even large objects such as horseshoes. The ostrich swallows them without hesitation. Coins can be the worst. Inside the ostrich they wear down to a razor-sharp edge. They will cut open the bird’s gizzard from the inside. When one young zoo ostrich died, 484 coins weighing more than eight pounds were found in its gizzard.小题1:

This nature reserve has had a lot of work done recently in order to help butterflies. Management of the land has included bringing in sheep to keep the grass under control in a more natural way and planting wild flowers for butterfly species. The nature reserve is home to a number of butterfly species. In fact the way that this reserve has been managed means that it is probably the best reserve in Hertfordshire to see butterflies with at least 25 species now living in the area.
There are a number of threats to British butterflies and the greatest threat is the loss of their habitat.

Successful people are nicer to those who are jealous of them, psychologists have found.
The fear that they may become the target of malicious（恶意的）envy makes people act more helpfully toward people who they think might be jealous of them.
Previous research found jealousy could be divided into benign and malicious envy. Those with benign envy were motivated to improve themselves, to do better so they could be more like the person they envied.52-------- The Dutch researchers then set out to question the effect on the target of the envy.
In lab experiments a group of people were made to feel like they would be maliciously envied by being told they would receive an award of five euros（欧元）53-------The researchers thought that the deserved prize would lead to benign envy, while the undeserved prize would lead to malicious envy.
Then the volunteer was asked to give time-consuming advice to a potentially envious person.People who had reason to think they would be the target of malicious envy were more likely to take the time to give advice than targets of benign envy.
In another experiment, an experimenter dropped a number of erasers on the floor as the volunteer was leaving.54-------- He said: "This sort of serves a useful group function. We all think better-off people should share with others but that"s not something we are inclined to do when we are better off..55----------
| A．Those who thought they would be maliciously envied were more likely to help him pick them up. |
| B．Helping others is a virtue. |
| C．However those with malicious envy wanted tobringthe more successful persondown. |
| D．Malicious envy. is terrible. |
F. People are more likely to help others if they think they are envious of them.
G.. Sometimes the prize was deserved and was based on the score they were told they had earned on a quiz. But sometimes it was not based on their score at all.
The survey said the Olympics not only built up China’s image but also served as an advertisement for China’s tourism.
The online survey was conducted on consumers in 16 countries and regions before Games’ opening ceremony and after the closing.
About 80 percent of the respondents had not been to China before the events and 50 percent of them expressed hopes of visiting China after the Games.
According to the survey, 70 percent of the respondents felt Beijing was more modern and scientific than what they had thought.
The most interested respondents were from Singapore, India, Mexico, South Africa and the Republic of Korea, as well as China’s Hong Kong and Taiwan.

In the early 16th century, people thought that dirt on the skin was a means to block out disease, as medical opinion had it that washing off dirt with hot water could open up the skin and let ills in. A particular danger was thought to lie in public baths. By 1538, the French king had closed the bath houses in his kingdom. So did the king of England in 1546. Thus began a long time when the rich and the poor in Europe lived with dirt in a friendly way. Henry IV, King of France, was famously dirty. Upon learning that a nobleman had taken a bath, the king ordered that, to avoid the attack of disease, the nobleman should not go out.
Though the belief in the merit of dirt was long-lived, dirt has no longer been regarded as a nice neighbor ever since the 18th century. Scientifically speaking, cleaning away dirt is good to health. Clean water supply and hand washing are practical means of preventing disease. Yet, it seems that standards of cleanliness have moved beyond science since World War Ⅱ. Advertisements repeatedly sell the idea; clothes need to be whiter than white, cloths ever softer, surfaces to shine. Has the hate for dirt, however, gone too far?
Attitudes to dirt still differ hugely nowadays. Many first-time parents nervously try to warn their children off touching dirt, which might be responsible for the spread of disease. On the contrary, Mary Ruebush, an American immunologist(免疫学家)，encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some ground.
小题1:The kings of France and England in the 16th century closed bath houses because .
| A．they lived healthily in a dirty environment. |
| B．they thought bath houses were to dirty to stay in |
| C．they believed disease could be spread in public baths |
| D．they considered bathing as the cause of skin disease |
| A．Afraid. | B．Curious. |
| C．Approving. | D．Uninterested. |
| A．By providing examples. |
| B．By making comparisons. |
| C．By following the order of time. |
| D．By following the order of importance. |
| A．To stress the role of dirt. |
| B．To introduce the history of dirt. |
| C．To call attention to the danger of dirt. |
| D．To present the change of views on dirt. |
