【解析】

试题分析:考查like和be busy的使用。Like作动词,表示“喜欢”,有like doing sth和like to do sth 两种用法,区别是like doing sth表示习惯性的一直喜欢做的某种事情或活动;like to do sth则含有一定的主观意愿,表示这个时候想做什么事情了,而不是强调一种习惯性的喜好。be busy doing sth,表示“忙于做某事”。句意:上文:你想和我出去露营吗?下文:我很乐意,但是我正忙于我的家庭作业。故选B。

考点:考查情态动词may的用法

Passenger pigeons(旅鸽) once flew over much of the United States in unbelievable numbers. Written accounts from the 18th and 19th centuries described flocks(群) so large that they darkened the sky for hours.

It was calculated that when its population reached its highest point, there were more than 3 billion passenger pigeons--a number equal to 24 to 40 percent of the total bird population in the United States, making it perhaps the most abundant bird in the world. Even as late as 1870 when their numbers had already become smaller, a flock believed to be 1 mile wide and 320 miles (about 515 kilometers) long was seen near Cincinnati.

Sadly, the abundance of passenger pigeons may have been their undoing. Where the birds were most abundant, people believed there was an ever-lasting supply and killed them by the thousands. Commercial hunters attracted them to small clearings with grain, waited until pigeons had settled to feed, then threw large nets over them, taking hundreds at a time. The birds were shipped to large cities and sold in restaurants.

By the closing decades of the 19th century, the hardwood forests where passenger pigeons nested had been damaged by Americans’ need for wood, which scattered (驱散) the flocks and forced the birds to go farther north, where cold temperatures and spring storms contributed to their decline. Soon the great flocks were gone, never to be seen again.

In 1897, the state of Michigan passed a law prohibiting the killing of passenger pigeons, but by then, no sizable flocks had been seen in the state for 10 years. The last confirmed wild pigeon in the United States was shot by a boy in Pike County, Ohio, in 1900. For a time, a few birds survived under human care. The last of them, known affectionately as Martha, died at the Cincinnati Zoological Garden on September 1, 1914.

Sally Ride was born on May 26th, 1951, in California. She started to play tennis at the age of 10 and became a good tennis player. But later, she thought she was not good enough to become a successful tennis player and then gave it up.

At the age of 22, she got a doctor’s degree. She was looking for a job when she read about NASA’s call for astronauts. More than 8,000 people wanted to join in the space program, but only Sally and other thirty-four other people were accepted.

After joining NASA in 1977, Sally Ride accepted training. She enjoyed flight training so much that flying became her favorite hobby. In 1983, Sally Ride became the first American woman in space on the shuttle Challenger ( STS-7)(挑战者号航天飞机). Her next flight was an eight- day task in 1984 on Challenger ( STS41-G ).

Sally Ride retired from NASA in 1987, then started an Internet-based NASA project. Sally Ride has received many awards, including the Jefferson Award for Public Service, the Woman’s Research and Education Institute’s American Woman Award.

Homework is an important part of education. However, what is it about homework? What makes it important?

First, homework helps students learn. Homework produces higher learning ability by asking the student to read the same text many times.

Most of the time, homework will ask students to read other books. So children have to read and understand it by themselves. Sometimes, parents must help children with this type of learning. Children hope to use what they have read to solve questions and problems in the homework.

Good use of homework makes children know that learning can happen with or without the teacher.As homework is finished, students learn to work out their own problems. Most students need a little help now and then, but doing homework is a way that children can learn to take care of themselves. If the student can do his or her own work, it is likely the ability he gets will be good for their future life.

Most homework gives room for additional(额外的) learning. Short answers, long answers and papers provide a way for students to learn things that interest them. Science can give the student a chance to go deeper into a field and have a better understanding. These things are almost impossible within the classroom education. If the project is done by a group, the students will also learn cooperation(合作).

Good study skills students get from homework and test preparation can be used easily in most work places.

Peter Onruang, a Hollywood businessman, has paid $310,000 to clone his best friend Wolfie, a lovely dog. He said, “Wolfie was more than just a pet to me.” Wolfie died two years ago, at the age of 15. But long before she and her sister Bubble passed away, Onruang had plans to bring them back to life. Onruang said, “I buried them at home. Each time I visit them, I say, ‘Hi, I’m making a new body for you.’”

Finally, Onruang found the South Korean biotechnology company RNL Bio, which can and will clone animals. Onruang collected his dogs’ stem cells (干细胞), and then he started a website MyFriendAgain.com, so he could earn and save the $310,000 that the cloning would cost.

The new dogs should look identical (完全相同的) to Wolfie and Bubble. When the cloning process is done, Onruang may end up with several clones of each dog. But Onruang admits he’s still not sure that they will be exactly the same.

Scientists cloned the first animal, a sheep named Dolly, in 1996 in Scotland. That project has raised ethical (伦理的) questions about where science should draw the line. Another question is whether such technique will lead to a day when humans could be cloned.

“If I had an opportunity to clone myself, I would do it readily,” Onruang said. “Because it’s me, I’m raising myself. I have already known exactly my strengths and weaknesses. This person is going to be the new and improved me, and will live the life I’ve always wanted to live.”

1.Onruang started the website MyFriendAgain.com in order to .

A. encourage more people to clone their pets

B. draw people’s attention to cloning

C. collect his dog’s stem cells

D. raise money to pay for the cloning

2.The purpose of the fourth paragraph is to tell us .

A. when and where scientists cloned the first sheep Dolly

B. people are in favor of the clone technology

C. there are arguments about the clone technology

D. cloning will be of great benefit to humans

3.What is Onruang’s attitude towards cloning humans?

A. He doesn’t care about it.

B. He is enthusiastic about it.

C. He strongly opposes it.

D. He never thinks about it.
