An allergy (过敏反应) is a strong reaction to a substance. Many things can cause allergies. The most common cause is pollen (花粉), which is usually produced by trees in the spring, grasses in the summer and weeds in the fall, as part of their reproductive process.
Other causes include organisms, chemicals, plants and dead skin particles (微粒) from dogs and cats can also cause allergic reactions. So can insect stings and some food.
The most common kind of allergic reactions is itchy (痒的), watery eyes and a blocked or watery nose. Allergies can also cause red, itchy skin. Some reactions can be life-threatening, for example, when breathing passages become blocked.
It is not always easy to avoid allergies. Drugs may offer an effective treatment. Another treatment used in some cases is called immunotherapy (免疫疗法). A patient is injected with small amounts of the allergy-causing substance. The idea is that larger and larger amounts are given over time until the patient develops a resistance in his body.
In the United States, experts estimate that up to 8% of young children have food allergies. Every year these allergies cause about 30,000 cases with severe reactions that require immediate treatment. It can result in breathing trouble and in some cases death. It is said that about 100 to 200 people will die. It says most of the reactions are caused by peanuts and tree nuts like walnuts.
People can also be allergic to medicines. The American Academy of Allergy, Asthma and Immunology says about 10% of bad reactions to commonly used medicines are allergic. In other words, a person’s immune system overreacts and produces an allergic reaction. The most common reactions include skin rashes (皮疹), itching, breathing problems and swelling in areas such as the face. Allergies seldom occur in winter because ______.

Language is always changing. In a society where life continues year after year with few changes, the language does not change either. The earliest known languages had difficult grammar but a small, limited vocabulary. Over the century, the grammar changed, and the vocabulary grew. For example, the English and Spanish people who came to America during the sixteenth century gave names to all the new plants and animals they found. In this way, hundreds of new words were introduced into English and Spanish vocabularies. Today life is changing very fast, and language is changing fast too.
There are several major language families in the world. Some scientists say there are nine main families, but other scientists divide them differently. The languages in each family are connected, and scientists think that they came from the same parent language. About 3 percent of the people in the world speak languages that are not in these major families. The early language had ________.

The young boy saw me, or rather, he saw the car and quickly ran up to me, eager to sell his bunches of bananas and bags of peanuts. Though he appeared to be about twelve, he seemed to have already known the bitterness of life. “Bananas 300 naira. Peanuts 200 naira.” He said in a low voice. I bargained him down to 200 total for the fruit and nuts. When he agreed, I handed him a 500 naira bill. He didn’t have change, so I told him not to worry. He said thanks and smiled a row of perfect teeth.
When, two weeks later, I saw the boy again, I was more aware of my position in a society where it’s not that uncommon to see a little boy who should be in school standing on the corner selling fruit in the burning sun. My parents had raised me to be aware of the advantage we had been afforded and the responsibility it brought to us. I pulled over and rolled down my window. He had a bunch of bananas and a bag of peanuts ready. I waved them away. “What’s up?” I asked him. “I … I don’t have money to buy books for school.” I reached into my pocket and handed him two fresh 500 naira bills. “Will this help?” I asked. He looked around nervously before taking the money. One thousand naira was a lot of money to someone whose family probably made about 5,000 naira or less each year. “Thank you, sir,” he said．“Thank you very much!”
When driving home, I wondered if my little friend actually used the money for schoolbooks. What if he’s a swindler? And then I wondered why I did it. Did I do it to make myself feel better? Was I using him? Later, I realized that I didn’t know his name or the least bit about him, nor did I think to ask.
Over the next six months, I was busy working in a news agency in northern Nigeria. Sometime after I returned, I went out for a drive. When I was about to pull over, the boy suddenly appeared by my window with a big smile ready on his face.
“Oh, gosh! Long time.”
“Are you in school now?” I asked. He nodded. “That’s good,” I said. A silence fell as we looked at each other, and then I realized what he wanted. “Here,” I held out a 500 naira bill. “Take this.” He shook his head and stepped back as if hurt. “What’s wrong?” I asked. “It’s a gift.” He shook his head again and brought his hand from behind his back. His face shone with sweat. He dropped a bunch of bananas and a bag of peanuts in the front seat before he said, “I’ve been waiting to give these to you.”It can be inferred from the first paragraph that _________.

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex.
In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent.
The study's participants were tested on science, maths, English and mechanical abilities.
Though there were twice as many men as women in the smartest group, there were also twice as many men among the bottom.
The aggregate（总数）scores of men and women were similar.
One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their homes.
"The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying.
The research tallies with past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds.
It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning.
A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds.
The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach.The purpose of the passage is to tell us that ________.
| A．man are smarter then women |
| B．man are more stupid the women |
| C．a new fact about the IQ of men and women has been found |
| D．men are more likely to receive first class university degrees |
According to Timothy Bates, less women are in the smartest group because _________.
| A．they are born stupid |
| B．they have to spend more time to tale care of their homes than men |
| C．they don’t like to take risk |
| D．they are not expected to be high achievers |

| A．agree with | B．deal with | C．go against | D．go with |
It can be inferred from the passage that_________.
| A．Women are steadier in their learning. |
| B．men are more ready to take risk in everything |
| C．women are securing more firsts and seconds |
| D．women are doing much better in academy |
