【题目】Eating too much fatty food,exercising too little and smoking can raise your future risk of heart disease. But there is another factor that can cause your heart problems more immediately:the air you breathe.

Previous studies have linked high exposure(暴露)to environmental pollution to an increased risk of heart problems, but two analyses now show that poor air quality can cause heart attack or stroke(中风) within as little as a few hours after exposure. In one report of the research, scientists found that people exposed to high levels of pollutants(污染物)were up to 5% more likely to suffer a heart attack within days of exposure than those with lower exposure. Another study of stroke patients showed that even air that the U.S. Environmental Protection Agency(EPA)considers to be of “moderate”(良好) quality and relatively safe for our health can raise the risk of stroke as much as 34% within 12 to 14 hours of exposure.

The authors of both studies stress that these risks are relatively small for healthy people and certainly modest compared with other risk factors such as smoking and high blood pressure. However, it is important to be aware of these dangers because everyone is exposed to air pollution regardless of lifestyle choices. So stricter regulation by the EPA of pollutants may not only improve environmental air quality but could also become necessary to protect public health.

【题目】James Cameron was born in a small town in Canada on August16,1954. At 15 he discovered what he wanted to do with his life. 【1】 The movie was Stanley Kubrick’s 2001: A Space Odyssey.

Cameron set his hope high. 2 But he didn’t know anything about cinema. What’s more, he lived far away from Hollywood, the place for him to realize his dreams.

__3__ His father told him they would be moving to California and living only a few miles from Hollywood. At that time, he had a great desire to attend film school, but his family couldn’t afford it. So he went to study physics at Fullerton College.

Before long Cameron dropped out of college and began earning his living as a truck driver. But he still hadn’t given up his dream of becoming a movie maker. His first professional film job was an art director in 1980, and in 1984 he wrote and directed the Terminator. 4_ after it came a series of successful science fiction action films.

Cameron now could do whatever he wanted. He had several projects in mind, including Titanic. 5 But it ended up earning almost $ 2 billion. After Titanic, Cameron started making Avatar in 2005. It took his team two years just to do the technical research, but the movie has become another huge success.

A. It was a huge success.

B. He wanted to make movies.

C. Cameron had to face the facts.

D. This movie cost $ 200 million to make.

E. owever, Cameron got a lucky break in 1971.

F. It happened one night after he saw a movie.

G. They used high technology to get the effects they wanted.

【题目】The sight of a mosquito can mean trouble to people in many parts of the world. The bite of the mosquito can be deadly. The insects carry serious diseases like malaria (疟疾). It is estimated that almost 630,000 people died from malaria and malariarelated causes in 2012, and most of these cases were in African countries.

In the United States, a group of California scientists are working to develop a more effective and less costly substance (物质) to protect people from mosquitoes. The researchers are investigating the sense of smell in mosquitoes. They found the insects use the same receptor for identifying carbon dioxide in human breath as they do for the smell of our skin. Anandasankar Ray, who is leading the investigation, says scientists tested more than a million chemical compounds (化合物) until they found a substance called Ethyl Pyruvate. He says Ethyl Pyruvate makes the mosquitoes' receptors inactive. “When we apply Ethyl Pyruvate to a human arm and offer it to hungry mosquitoes in a cage, very few of the mosquitoes are attracted to the human arm because only a few of them are able to smell it out,” said Ray.

Genevieve Tauxe, a member of the research team, says it was not easy to find the neurons (神经元) of noble cells that recognize both the smell of human breath and skin. “With the device used to examine the mosquito, we are able to insert a very small electrode (电极) into the part of the mosquito's nose, where its smelling neurons are and where the smell is happening,” said Tauxe.

Anandasankar Ray says a product based on Ethyl Pyruvate may cost less to produce than DEFT, the most effective chemical treatment now in use. He says DEFT is too costly for most people who live in areas affected by malaria.

“Perhaps by finding smells that can attack other target receptors, we will be able to improve upon DEFT and finally have the next generation of insect behaviour control products,” said Ray.ytytzygx.

【题目】On January 11, 2007, as students sat and listened, a very important guest speaker named Richard, spoke to the students in the lecture hall. He not only showed the potential(潜能)within young adults, but encouraged them to work hard at their lessons.

Richard was a young child when his mother died and his father walked out. He was forced into many different foster homes(寄养家庭)where he felt unhappy. He did not know that his life was taking a turn for the worst.

His uncle, after getting out of prison, got him into drugs and alcohol. His uncle taught him that his place in life was either to be in prison or die trying to be “a man.” His uncle’s teaching almost started affecting him until a very important person came into his life: a teacher. This teacher taught him there is a place in the world for everyone and it isn’t related to drugs.

Richard is now a Harvard University graduate and has a great and loving family. Why? He was taught to have respect not only for others, but for himself.

After the meeting, it was hoped that the students realized within them there is a potential, and within everyone around them, is knowledge. As Richard reminded them, “Knowledge is power.”

【题目】根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。

Lately, there is a rising trend in families choosing to homeschool their child than send their child to a traditional educational institution. Let’s look at some of the benefits of homeschooling.

1. Flexible Schedule

Homeschooling enables a flexible schedule. 【1】 With homeschooling, your child can start homeschooling at 9 am or later depending on your preferred schedule. You can schedule your child’s homeschooling education as you see fit with materials or subjects that may be not available in a traditional school.

2. Individual Attention

With homeschooling, your child gets all the individual attention. For example, if your child is weak in maths, you could devote more time and energy to teaching maths. Your child’s homeschooling schedule can be adjusted for that. For example, if your child is better at science than at maths, simply devote more homeschooling hours to maths and cut back on science. With homeschooling, the choice is yours. 2

3. Family Activity

The schooling of the child can become an extended family activity. Examples are field trips and experiments. Plus, the child also receives more quality time with his/her parents. 3 The child is also free of any negative peer pressure or influences.

4. 4

With homeschooling, the child does not need to prove his/her abilities to other children. Parents are able to plan the learning program according to his strengths and weakness.

Parents can also change the curriculum to suit the learning style of the child. 5 Some children even learn better from experiencing or seeing things in action.

A. No peer pressure

B. Religion Learning

C. Traditional schools can’t do that.

D. There is more time for family bonding.

E. For example, the child needn’t wake up at 7 every morning.

F. Plus, it is quite impossible to provide individual attention to all students.

G. For example, some children learn better from reading while others need to write.
