James Joyce was an Irish novelist who revolutionized the methods of depicting characters and developing a plot in modern fiction. his astonishing way of constructing a novel, his frank portrayal（描画, 描写）of human nature in his books, and his complete command of English have made him one of the outstanding influences on literature in the 20th century. Many critics judge that he is second only to Shakespeare in his mastery of the English language. Joyce was deeply influenced by Ireland and wrote all his books about Dublin.
When he was in Dublin College, he studied languages and spent his spare time reading books. He refused to take part in the nationalist movement like his fellow students, but he became passionately（热情地, 热烈地）interested in literature. He wrote outspoken articles of literary criticism that shocked his teachers and even taught himself norwegian（挪威语）so that he could read Ibsen’s（挪威剧作家及诗人）works in the original.
When he graduated in 1902, he knew he would become a writer and an exile（流犯, 被放逐者）, because he felt he could not be one without the other. In order to preserve his ideal of writing truthfully, fully, and as objectively as he knew how, about the people and places he knew best, he had to escape from all temptations to become involved in popular opinion or public life. He went to France, Italy and Switzerland, where he lived in poverty and obscurity for the first 20 years, only returning to Ireland when his mother was dying. Except for a couple of brief trips, he stayed abroad all his life.

A new report said that different types of plants can release some chemical into the air to help other plants. These chemical warnings all have the same purpose — to spread information about one plant's disease or infestation so other plants can defend themselves. But exactly how plants receive and act on many of these signals is still mysterious.
In this week’s Proceedings of the National Academy of Sciences, researchers in Japan offered some explanations. They had identified one chemical message and traced it all the way from release to action.
The scientists looked at tomato plants infested by a common pest, the cutworm. The researchers studied leaves from exposed and unexposed plants. They found one compound showed up more often in the exposed plants. The substance is called Hex Vic. When the scientists fed Hex Vic to cutworms, it knocked down their survival rate by 17%. The scientists identified the source of Hex Vic, and sprayed it lightly over healthy plants. Those plants were then able to start producing the cutworm-killing Hex Vic. Researchers confirmed that uninfected plants have to build their own weapons to fight off bugs and disease. How do they know when to play defense? They are warned first by their friendly plant neighbors.
It is a complex tale, and it may be happening in more plant species than tomatoes. It may also be happening with more chemical signals that are still unknown to us. Further studies are needed to increase agricultural efficiency.
1.Which is the way used by plants to warn their neighbors?
A. Using of winds.
B. Identifying the chemicals.
C. Releasing some chemicals.
D. Being exposed early.
2.It can be inferred from the text that ________.
A. farmers may benefit from the further studies
B. the phenomenon may be happening in less plant species than tomatoes
C. there are not chemical signals
D. plants are warned first by their neighbors
3.What’s the function of Hex Vic?
A. It sprays over healthy plants.
B. It shows up more.
C. It cures the disease.
D. It damages the cutworm’s body.
4.The passage is likely to appear in ________.
A. a newspaper advertisement
B. a physics textbook
C. a science magazine
D. a finance report

Some problems are difficult to solve. But there are a lot of number expressions that can help. For example, if we put two and two together, we might come up with the right answer. We know that two heads are better than one. It is always better to work with another person to solve a problem. Some problems have only one solution. You cannot be of two minds over this. But with any luck，we can solve the problem in two shakes of a lamb’s tail. In other words，we could have our answers quickly and easily.
Sometimes we can kill two birds with one stone. That is, we can complete two goals with only one effort or action. But we must remember that two wrongs don’t make a right. If someone does something bad to you, you should not do the same to him.
If you are going out with your girlfriend，or boyfriend，but you don’t want another friend to go along on your date，you can just say to your friend: two’s company, three’s a crowd.
When I was a young child in school, I had to learn the three R’ s. These important skills are reading, writing and arithmetic. These three words do not all start with the letter “R”.

Some of my friends were confused and did not understand their school work. They were at sixes and sevens. In fact, they did not care if they finished high school. But they were happy when they completed their studies and graduated from high school. They were in seventh heaven. They were on cloud nine.

Twenty minutes of exercise may help kids with ADHD(小儿多动症) settle in to read or solve a math problem, a new research suggests.
The small study, of 40 8～10 year-olds, looked only at the short-term effects of a single period time of exercise. But researchers warn that they are not saying exercise is the answer to ADHD.
But it seems that exercise may at least do no harm to kids' ability to focus, they say. And further studies should look into whether it's a good choice for managing some children's ADHD.
“This is only a first study,” said lead researcher Matthew B. Pontifex, of Michigan State University in East Lansing.
“We need to learn how long the effects last, and how exercise might combine with or compare to traditional ADHD treatments” like stimulant medications(刺激性药物), Pontifex explained.
He noted that there's been a lot of research into older adults. But little is known about kids, even though some parents, teachers and doctors have advocated exercise for helping children with ADHD.
So for their study, Pontifex and his colleagues found 20 children with diagnosed(诊断) or suspected ADHD, and 20 ADHD-free kids of the same age and family-income level.
All of the children took a standard test of their ability to ignore distractions(注意力分散) and stay focused on a simple task at hand - the main ability” that troubles kids with ADHD, Pontifex noted. The kids also took standard tests of reading, spelling and math skills.
Each child took the tests after either 20 minutes of treadmill(跑步机) exercise or 20 minutes of quiet reading (on separate days). Overall, the study found, both groups of children performed better after exercise than after reading.
On the test of focusing ability, the ADHD group was correct on about 80 percent of responses after reading, versus(相对于) about 84 percent after exercise. Kids without ADHD performed better -reaching about a 90 percent correct rate after exercise.
Similarly, both groups of kids scored higher on their reading and math tests after exercise, versus post-reading.
1.What does the new research suggest?
A.Exercising will make kids with ADHD stronger.
B.Exercising will help kids with ADHD focus better.
C.Exercising will help make math problems easier.
D.Exercising will help kids read more quickly.
2.What is the problem about the research into kids?
A.There is too much research into the older adults.
B.The research about the ADHD is enough.
C.The research about kids with ADHD is limited.
D.Exercise is not combined with traditional treatment.
3.Why did Pontifex’s team need 20 ADHD –free kids during the research?
A.They need to compare their performance with that of kids with ADHD.
B.They need them to do some reading and math problems after school.
C.They need them to take a standard test of their ability to ignore distractions.
D.They need them to take standard tests of reading, spelling and math skills.
4.What happened to the kids after exercising?
A.Kids with ADHD performed better than kids without ADHD in reading.
B.Kids without ADHD performed the same before and after exercising.
C.Both groups scored higher on their reading and math tests after reading.
D.Both kids with ADHD and without ADHD performed better after exercise.
