Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic talked about by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only can these two diseases be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life can be longer.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial family being a good example, have hereditary (遗传的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing with hereditary diseases. But gene technology can solve this problem perfectly. The scientists just need to find the wrong gene and correct it, and a healthy child will be born.
Some people are worrying that the gene research can be used to make human beings in large quantities. In the past few years, scientists have succeeded in cloning babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
What does “these two killers” in the second paragraph refer to?

A．Gene technology and another treatment of the two diseases.

B．The two murderers who killed the cloned baby.

C．Hereditary disease and cancer.

D．Cancer and heart disease.

In what way can gene technology help to treat hereditary diseases?

A．Using gene technology, a scientist finds the wrong gene and corrects it.

B．Using gene technology, people with hereditary diseases can live longer.

C．Using gene technology, human babies can also be cloned.

D．Doctors can cure cancer and heart disease with the help of gene technology.

What is the main purpose of writing the text?

A．Explaining that gene technology will also do great harm to human race.

B．Telling the readers the positive effects gene technology has on people’s life.

C．Expressing the writer’s idea that gene technology will benefit people.

D．Informing people that gene technology helps clone babies in large quantities.

The worst danger is a house on fire when people are asleep. Always be ready to leave through a window into the garden by making sure you can open it if necessary. If you should be on holiday in a tall building or hotel, make sure you know where the fire escape(太平梯) is. When you can’t find any way out, try to find pieces of cloth and make a rope to get out of a window to safety. If you smell burning in your home, get out right away. If you can’t breathe properly because of smoke on your way out, crawl(爬) on your hands and knees because smoke rises and the air will be cleaner near the floor. Smoke is a killer and more people die from breathing it in than actually being burned.
Fire in a cinema hall or public place often means people pushing to reach a door. Keep your head up with arms up in front of your chest. This protects your chest and gives you the best chance to breathe. Above all, don’t get frightened!

Special trees that grow faster, fight pollution, produce better wood, and even sense chemical attacks are being planted by scientists in the US.
When 40 per cent of Hawaii's US$14 million-a-year papaya (木瓜)industry was destroyed by a virus five years ago, work began on creating genetically engineered (转基因的) trees.
Researchers successfully introduced seeds that were designed to resist the virus. Since then, more and more people have been testing genetically engineered trees.
Some researchers put special bacteria into trees to help them grow faster and produce better wood. Others are trying to create trees that can clean polluted soil.
Meanwhile fruit farmers are looking for trees that are strong enough to resist worms, and paper companies want trees that produce more wood and therefore more paper.
The Pentagon (五角大楼) even gave the researchers US$500,000 this year after they developed a pine tree that changes its colours if it senses a chemical attack.
So far, the poplar, eucalyptus (杨树与桉树), apple and coffee trees are among those being engineered. All this can be done today because we have a better understanding of tree genomes (基因组).
However, some people fear that the genetically engineered trees will cause dangerous results. They are worried that the new trees will breed with natural species and change the balance of the forest environment.
"It could be destructive," said Jim Diamond, an environmentalist. "Trees are what is left of our natural environment and home to many endangered species."
But researchers insist that science could give nature a fighting chance against both natural and man-made dangers.
They hope to answer the critics by stopping the new trees from breeding, so their effect on the environment can be controlled.
57. Which kind of tree is not the ones that scientists are planting in the US?
A. Trees that worms can't hurt.
B. Trees that can protect themselves at a chemical attack.
C. Trees that can resist wind better.
D. Genetically engineered trees.
58. What caused the American scientists to work on special trees?
A. They think science could give nature a fighting chance against both natural and man-made dangers.
B. Great numbers of trees have been lost due to attacks by viruses.
C. Researchers successfully introduced seeds designed to resist the virus.
D. Tree genomes are mapped out so scientists know how to improve trees.
59. Which of the following was probably the first kind of trees being engineered?
A. Papaya. B. Pine. C. Apple. D. Poplar.
60. Why did critics think engineered trees dangerous? Because _______.
A. these trees can destroy the balance of nature
B. everything except trees has been genetically engineered
C. trees are home to many endangered species
D. these trees may affect normal trees

“Up until about five years ago, students at this school could have worn anything they wanted on Halloween,” said Rosemarie Nielson, a sixth-grade teacher at St. Theresa School, a Roman Catholic elementary school in the Pelham Bay section of the Bronx where there is a prohibition on toy weapons.
“When you consider all the horrific things that have happened in recent years, including 9/11, I can’t blame any school for wanting to stay away from anything that might promote violence,” Ms. Nielson said.
Mary Ellen Manniello, whose daughter, Courtney, 9, is a fourth grader at St. Gabriel School, a Roman Catholic elementary school in the Riverdale section of the Bronx, said she understood why officials had banned weapons with costumes. “They’re learning more about guns from issues in the street than educational issues.”
This year, the school has gone one step further and is prohibiting all costumes at its Halloween festivities. Ms. Manniello said it had become “a chaotic scene,” with parents helping their children change into their costumes at school.
Some parents said the no-weapons policy for Halloween costumes went too far and denied children a chance to express themselves.
“Halloween has always been the one day when it was acceptable for our children to be dressed like somebody they are not, like a cowboy or a pirate or a person from outer space, and now we’re taking that away from them,” said Laura Santoro, a nurse from New Milford, Conn., whose 7-year-old son, Johnny, is a second grader at Northville Elementary School there.
Ms. Santoro said that her son would dress as Capt. Jack Sparrow, the character played by Johnny Depp in the “Pirates of the Caribbean” movies, at the school’s Halloween party, but that he would not be allowed to take a sword — part of a policy that caught her by surprise last Halloween.
“I sent my son to school last year dressed as a special force Power Ranger, and he was told that he couldn’t take along his red laser blaster, which really surprised me, because the laser is red and made of plastic and lights up, and it could never, ever be mistaken for a real gun,” Ms. Santoro said. “I mean, come on, the whole thing is getting really sad.”
53. What do you think is the writer’s purpose of writing the passage?
A. To introduce to the public the no-weapons policy for Halloween costumes.
B. To state parents’ attitudes towards the no-weapons policy for Halloween costumes.
C. To tell the public that children should bring any weapons for Halloween costumes.
D. To analyse the fact that the no-weapons policy for Halloween costumes goes too far.
54. According to the passage, some parents understand the no-weapon policy for Halloween costumes because ____________.
A. schools should take a cautious approach to Halloween to prevent violence.
B. children are buying real guns in the street and there is always violence now.
C. those parents like to help their children change into their costumes at school.
D. children are learning more about guns from educational issues.
55. Which of the following is probably right according to the passage?
A. Children could bring any weapons into school five or six years ago.
B. The parents surveyed are those whose children are in elementary schools.
C. Guns are necessary on Halloween for children to express themselves.
D. Jack Sparrow is an actor who at one time acted as a pirate in a movie.
56. What do the underlined words “laser blaster” in the last paragraph refer to?
A. A kind of costume. B. A real gun.
C. A toy weapon. D. A kind of plastic.

C
Play is the basic business of childhood, and in recent years research has shown the great importance of play in the development of a human being. From earliest infancy (婴儿), every child needs opportunity and right materials for play, and the main tools of play are toys. The main function of toys is to suggest, encourage and play. To succeed in this, they must be good toys, which children will play with often, and will come back again and again. Therefore, it is important to choose suitable toys for different stages of a child’s development.
In recent years research on infant development has shown that the standard a child is likely to reach, within the range of his inherited abilities, is largely determined in the first three years of his life. So a baby’s ability to benefit from the right play materials should not be underestimated. A baby who is encouraged, talked to and shown things and played with, has the best chance of growing up successfully.
In the next stage, from three to five years old, curiosity knows no bounds. Every type of suitable toys should be made available to the child, for trying out, experimenting and learning, for discovering his own particular ability: Bricks and jigsaws and construction toys; painting, scribbling and making things; sand and water play; toys for imaginative and pretending play—the first social games for learning to play and get on with others.
But at the third stage of play development—from five to seven or eight years old— the child is at school. But for a few more years play is still the best way of learning, at home or at school. It is easier to see which type of toys the child most enjoys.
Until the age of seven or eight, play and work mean much the same to a child. But once reading has been mastered, then books become the main source of learning. Toys are still interesting and valuable, which lead up to new hobbies, but their significance has changed to a child of nine or ten years old, toys and games mean, as to adults, relaxation and fun.
49. According to the first passage we know that as a child grows up ______.
A. he should be allowed to choose his own toys.
B. he should be given the same toys.
C. he should be given fewer and fewer toys.
D. he should be given different toys.
50. According to the passage, the abilities a child has inherited from his parents ______.
A. determine his character
B. will not change after the age of three.
C. partly determined the standard he is likely to reach
D. to a large extent determine the choice of toys
51. We learn from the passage that a child has boundless curiosity ______.
A. when he is two                    B. when he is around four
C. when he is six                     D. when he is eight
52. The passage is mainly about _______.
A. the role of play in a child’s development       B. the importance of schooling
C. the importance of pre-school education        D. the choice of toys for youngster
