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 merit (优点) 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. 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 too dirty to stay in |
| C．they believed disease could be spread in public baths |
| D．they considered bathing as the cause of skin disease |
Which of the following best describes Henry IV's attitude to bathing?
| A．Afraid. | B．Curious. | C．Approving. | D．Uninterested. |
How does the passage mainly develop?
| A．By providing examples. |
| B．By making comparisons (比较). |
| C．By following the order of time. |
| D．By following the order of importance. |
What is the author's purpose in writing the passage?
| 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. |
YOUR mom might cook a bowl of noodles for you on your birthday. But in the US, a mom makes a cupcake for her children on their birthday.
Cupcakes are small, round cakes topped with frosting (糖霜). It has been an American tradition that moms bring cupcakes to the classroom to celebrate their child’s birthday.
But recently some doctors have called for this to be banned. They believe cupcakes contribute to child obesity.
Despite their good intentions, however, some people believe that experts are interfering (妨碍) with American culture. The cupcake is seen as American as apple pie — only prettier.
According to Marion Nestle, a professor of nutrition at New York University, the cupcake is the most democratic (民主的) of desserts. As they are small enough for one person, you don’t have to share your cupcake with anyone — it’s all yours. They are also all the same size, so there can’t be any cries of 
“she got the bigger piece!”
Each bite can taste different depending on how much icing you have. It is a lesson in self- determination. Some people eat only a little of the frosting every time, others have it all in just one bite.
In recent years, eating a cupcake has become as trendy as having a cup of Starbucks coffee.
Democratic presidential candidate Hillary Clinton jokingly promised on a talk show that if she was electe
d president, she would give everyone a cupcake on her birthday.
Ruth Reichl, editor-in-chief of Gourmet magazine, explains that the rise of the cupcake is very much about going back to American national identity in food, which is all about comfort. “People want to think about when they and their country were innocent,” she said.According to the passage, it has been an American tradition that ___________.
| A．the family holds a party for children on their birthday |
| B．a mom cooks a bowl of noodles for her children on their birthday |
C．a mom makes a cupcake for her children on their birt hday and brings it to the classroom |
| D．parents go travelling with their children on their birthday |
Why do doctors ask people to ban cupcakes on children’s birthday?
| A．Because they themselves don’t like cupcakes. |
| B．Because they think cupcakes are not so delicious. |
| C．Because they believe cupcakes will cause cries of “She got the bigger piece”. |
| D．Because they believe cupcakes are one of the causes to make children become fat. |
What cannot be inferred according to Marion Nestle?
| A．The cupcake is more democratic than any other desserts in the US. |
| B．The cupcake is too small to share with others. |
| C．The sizes of cupcakes are the same so it’s equal to everyone. |
| D．Cupcakes will lead to child obesity so they should be banned. |
The underlined word “trendy” in paragraph 7 probably means ________.
| A．popular | B．gentle | C．delicious | D．different |
Why did the writer mention Hillary Clinton and Ruth Reichl?
| A．To arouse the readers’ attention to banning the tradition of making cupcakes. |
| B．To show that cupcakes are becoming a popular way to show kindness and comfort. |
| C．To make a comparison between them in order for readers to remember them. |
| D．To give readers some idea of cupcakes so as to better understand the American culture |
A few days ago I asked my sons’ governess Julia to come into my study.
“Be seated, Julia,” I said. “Let’s settle our accounts. I guess you most likely need some money, but maybe you’re too polite to mention it. Now then, we agreed on thirty dollars a month...”
“Forty.”
“No, thirty. I made a note of it. I always pay our governess thirty. Well, hmm, you’ve been here two months, so...”
“Two months and five days.”
“Exactly two months. I made a special note of it. That means you have sixty dollars coming to you. Take off nine Sundays... You know you didn’t work with Tom on Sundays. You only took walks. And three holidays...”
Julia was biting her finger nail nervously, her face red, but—not a word.
“Three holidays, therefore take off twelve dollars. Four days Tom was sick and there were no lessons, as you were occupied only with Dick. Three days you had a toothache and my wife gave you permission not to work after lunch. Twelve and seven—nineteen. Take nineteen off...that leaves...hmm...forty one dollars. Correct?”
Julia’s left eye reddened with tears welling up. Her chin trembled；she coughed nervously and blew her nose, but—still not a word.
“Around New Year’s Day you broke a teacup and a saucer: take off two dollars. The cup cost more, it was a treasure of the family, but—forget it. When didn’t I take a loss?! Then, due to your carelessness the maid stole Dick’s shoes. You ought to watch everything! You get paid for it. So, that means five more dollars off. The tenth of January I gave you ten dollars.”
“You didn’t,” sobbed Julia.
“But I made a note of it.”
“Well...if you say so.”
“Take twenty seven from forty one—that leaves fourteen. ”
Both her eyes were filled with tears. Beads of sweat stood on the thin pretty little nose. Poor girl!
“Only once was I given any money,” she whispered, her voice trembling, “and that was by your wife. Three dollars, nothing more.”
“Really? You see now, and I didn’t know that! Take three from fourteen...leaves eleven. Here’s your money, my dear. Three, three, three, one and one. Here it is!”
I handed her eleven dollars. She took them and pocketed them.
“Merci(法语，谢谢),” she whispered.
I jumped to my feet and started pacing the room. I was overcome with anger.
“For what, this ‘merci’?”I asked.
“For the money.”
“But you know I’ve cheated you—robbed you! I have actually stolen from you! Why this ‘Merci’?”
“In my other places they didn’t give me anything at all. ”
“They didn’t give you anything? No wonder! I played a little joke on you, a cruel lesson, just to teach you...I’m going to give you all the eighty dollars! Here they are in the envelope all ready for you...Is it really possible to be so spineless（懦弱）? Why didn’t you protest? Why were you silent? Is it possible in this world to be without teeth and claws（爪）—to be such a fool?”
Embarrassed, she smiled. And I could read her expression: “It is possible.”
I asked her pardon for the cruel lesson and, to her great surprise, gave her the eighty dollars. She murmured her little “merci” several times and went out. I looked after her and thought: “How easy it is to crush the weak in this world!”While talking to Julia, the writer expected ____________ from her.

In many societies, there is often greater acceptance of light skin than dark skin. Light skin may be seen as a mark of beauty, intelligence and success. These beliefs can lead to social pressures even within the same racial or ethnic group, if some members are darker skinned than others.
The result is that skin lightening has become a common activity across Africa, Asia and other areas of the world. More and more people with dark s
kin are using skin-lightening products, even if it means they may face health risks.
They believe that having whiter skin will improve their lives. Many people think they will have a better chance of getting a job or marrying into a better family. Or they want to look like what their society generally considers beautiful.
Some beauty care products and soaps contain chemicals that make skin lighter. This is also called bleaching. But some of the chemicals are extremely dangerous. One of the most dangerous is hydroquinone(对苯二酚).
Hydroquinone has been banned in several countries. This chemical has been connected to kidney damage and some kinds of cancer. It also causes low birth weight in babies when mothers –to-be use it during pregnancy.
At first, bleaching products make the skin color lighter. But after long-term use they can cause problems. They could even make some skin darker.
The chemicals in the products block and break down the natural process that gives color to skin. The skin loses its natural barrier（障碍）to protect against sunlight. Then the skin can become thick and discolored. Usually the person will use more of the product in an effort to correct the problem, but this only makes it worse.
Fatimata Ly treats skin conditions in the Senegalese capital, Dakar. Doctor Ly says skin bleaching has become a problem throughout Senegal. She says the chemicals are now more dangerous because they are stronger. Some cases have resulted in blackened fingernails, infections and permanent（永久的）skin damage.
And these are not the only risks. Experts say some people who change their skin color suffer emotional damage. They feel regret and sadness. They feel that instead of risking their health, they should have learned to love and accept their skin color as it was.What is the text mainly about?
| A．The advantages of light skin | B．Introducing skin lightening products |

What does the underlined word “bleaching” refer to?
| A．The process of removing the color |
| B．The process of making the skin whiter |

DNA is one of the most important discoveries in science. DNA is the plan for the human being, as a blueprint is the plan for a building. DNA makes a person look the way he does. A person’s DNA comes from a mixing of his parents’ DNA. That’s why a child looks like his parents. But, besides controlling things such as height and hair color, DNA can also give people diseases. Scientists are now studying DNA to cure diseases.
In the seventies, scientists developed a process called recombinant or RDNA. Although it sounds difficult to understand, RDNA simply means taking DNA from one animal or plant and putting it into another. By doing so, scientists can create new beings. In doing so, scientists can better understand DNA, especially what parts of DNA do what. After they understand DNA, scientists can begin to cure diseases. Often, the new being created will itself be the cure. Besides curing diseases, RDNA research can also do other things. For example, scientists in Japan have already created “super-trees”. Trees help humans, because they take CO2, which poisons humans, from the air and turns it into oxygen, which lets humans breathe. “Super-trees” do this too, but do it much faster. As things such as cars and factories have already put much CO2 in the area, “super-trees” are badly needed.
Unfortunately, there is a serious danger in RDNA research. Scientists want to create animals to cure old diseases, but these new animals may also create new diseases. It will be a serious problem if the animals escape from the science laboratory and into nature. As these animals are not natural, they may let loose many new powerful diseases.
As a result, RDNA research will create many solutions, but it will also create many problems.

Life gets noisier every day and very few people can be free from noise of some sort or another. It doesn’t matter where you live-in the middle of a modern city, or a faraway village-the chances that you will be disturbed by jet aeroplanes, transistor radios, oil-powered engines, etc. are almost everywhere .We seem to be getting used to noise, too. Some people feel quite lonely without background music while they are working.
Scientific tests have shown that total silence can be very frightening experience for human beings. However, some people enjoy listening to pop music which is very loud, and this can do harm to their eardrums(耳鼓).The noise level in some disco is far above the usual safety level for heavy industrial areas.
A recent report about noise and concentration(专心) suggested that although a lot of people say that any noise disturbs their concentration, what really affects their ability to concentrate is a change in the level of noise. It goes on to say that a background noise, which doesn’t change too much (music, for example) may even help people to concentrate.The best title for this passage is _______________.
