【題目】閱讀下面短文,然后用60個單詞左右概括短文的要點。
Getting rid of dirt, in the opinion of most people, is a good thing. However, there is nothing fixed about attitudes to dirt.
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 advantage 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 (免疫學家), encourages children to play in the dirt to build up a strong immune system. And the latter position is gaining some reason.

【答案】People have mixed opinions towards dirt on our skin. For a long time in history, people of some European countries, such as France, believed that dirt protected people from getting ill. However, people began to change their attitudes to dirt about 200 years ago. People have been told that washing dirt off our body can keep us healthy. But, some scientists believe that exposure to some dirt many help our immune system.
【解析】本文主要講了在不同的歷史時期人們對于泥的態(tài)度,以及泥對于身體健康的影響。在歷史上的很長時期,一些歐洲國家認為泥可以保護人們免受疾病,而在十八世紀,人們開始改變了這個觀點,科學表明把身上的贓物洗干凈有利于健康,但是也有科學家認為泥可以幫助我們維持免疫系統(tǒng)。

The giant panda loves bamboo. An adult panda requires 12.5 kilograms of bamboo, which it(hungry) pulls out with its powerful paws, to satisfy its daily needs. Wild pandas live only in the high bamboo forests of Central China. These mountain forests are cool and wet--just as pandas like it. In the summer, they may climb as high as 4000 meters to help themselves to bamboo (grow) at higher altitudes. Frequently, pandas(see) eating in a relaxed sitting position, with their back legs stretched out before them. they may appear inactive, they are in fact skilled tree-climbers and efficient swimmers.
Giant pandas are unsociable. They have a highly developed sense of smell that males use(avoid) each other and to find females for mating in the spring. After a five-month pregnancy, a female gives birth a cub. The blind baby pandas weigh only 142 grams and cannot crawl(爬行) they reach three months of age are born white, and develop their much loved coloring later.
