题目内容
A recent online poll (民意调查) asked kids what they hated most about school. “Classes are boring” came in first. “Too much homework” was a close second. Since all activities remain interesting for only so long, too much homework can lead to ennui. So, why are some kids getting homework overload? Teachers give two reasons. First, they say, the government now requires schools to meet higher-than-ever achievement goals for students. If students don’ t succeed, the school faces punishment. Second, many parents want their children to be able to get into the best colleges and universities. These parents believe homework is a way to ensure that students are learning as much as possible.
People who favor homework argue that it can have many beneficial effects. They claim it can help students develop good study habits. Homework can help students recognize that learning can occur at home as well as at school. It can help develop their independent learning and responsible character traits(性格特征).
But studies show that middle school students doing 60 to 90 minutes of homework a night are doing just as well in school as those doing more than 90 minutes. And homework can have negative effects. Homework can deny students access to leisure(休闲) activities that also teach important skills. For example, sports teams teach cooperation and leadership, in addition to helping kids stay physically active. Another problem with too much homework is that parents can get too involved. They can put too much pressure on their kids.
So what should be done? Good homework assignments in the proper amount will have positive effects. Too much homework, however, will have negative effects. The bottom line: Students in grades three through six should do no more than 30 to 60 minutes of homework each night.
1.The underline word “ennui” in Paragraph 2 can be replaced by “______” .
A. relaxation B. fancy C. boredom D. intelligence
2. According to Paragraph 1, the kids are given much homework because ________.
A. schools are evaluated in terms of students’ achievement.
B. the government doesn’t take the problem seriously
C. it is a good way to improve the students’ ability

3.Those who are in favor of homework think that _______.
A. homework helps students to succeed
B. it’s good for kids to help each other in learning
C. parents are a great help when kids do homework at home
D. homework helps children to learn independently
4. Which of the following is NOT a negative effect of too much homework?
A. Kids have little time to do leisure activities.
B. There is a lack of sleeping time.
C. The chances of learning other skills are lost.
D. Kids are under pressure from their parents.

Researchers in over 80 nations are taking part in a project to conduct a decade-long census(统计) of sea life. Scientists presented some of their findings at a recent conference as the project neared its completion.
In deep icy waters under Antarctica, scientists found bulbous tunicates, an underground animal, and many newly-discovered creatures believed to be related to starfish (海星) and other marine(海洋的)creatures.
Elsewhere in the world’s oceans, they have recently discovered many kinds of underwater life forms new to science. It is all part of a research effort called the Census of Marine Life.
“There are about 2,000 scientists worldwide involved,” said Bob Gagosian, President, CEO of the Consortium for Ocean Leadership. Gagosian helps manage the project. “Everywhere they’ve gone they’ve found new things,” he says. “The ocean basically is unexplored from the point of view of marine living things.”
Researchers have placed small markers on hundreds of fish and marine animals to track by satellite their migration(迁移)routes and to discover places where sea life gathers.
According to Ron O’Dor, a senior scientist with the Census of Marine Life, knowledge of life on the ocean floor is especially limited. “90% of all the information we have is from the top hundred meters of the ocean,” O’Dor states.
And he says the sea floor is, on average, at a depth of 4, 000 meters. And so, as some machines dive far below what people have previously seen, scientists are discovering new species of plants, animals and living things.
Since the census project began, more than 5,300 new marine animals have been found. Ocean researchers say they hope to catalogue 230,000 species during the census —which some say is only a small part of all the creatures living in the sea.
1.Why do the researchers place small markers on many marine creatures?
A.To catch them. |
B.To research them. |
C.To kill them. |
D.To protect them. |
2.From what Ron O’Dor says, we can conclude that .
A.human beings only know a little about marine life |
B.the oceans don’t need to be further explored |
C.he considers exploring the ocean a dangerous thing |
D.the marine creatures mainly live on the top of the ocean |
3.What can we learn from the passage?
A.About 2,000 scientists from America are involved in the project. |
B.The census of sea life will last for ten years. |
C.230,000 new marine animals have been found. |
D.The sea floor is at a depth of 400 meters. |
4.Why does the author write the passage?
A.To tell the news that new marine creatures are being discovered |
B.To encourage people to find new marine creatures |
C.To prove the importance of marine creatures |
D.To introduce the newly-discovered creatures. |
