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 discussed 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 these two diseases can 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 span(寿命) can be prolonged.
Gene technology can help people to give birth to 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 about hereditary diseases. But gene technology can solve this problem perfectly. The scientist 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 manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep, therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the government 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．The two diseases of cancer and heart disease. |
| D．Hereditary diseases and cancer. |
What’s the main idea of the third paragraph?
| A．How gene technology can be applied in the field of treating hereditary diseases. |
| B．Gene technology can be used to clone human babies. |
| C．Gene technology can help people to give birth to a baby. |
| D．Gene technology can help the English imperial family out. |
In what way gene technology can help to treat hereditary diseases?
| A．Using gene technology, people with hereditary diseases can have more living days. |
| B．Using gene technology, the scientist finds the wrong gene and corrects it. |
| C．Using gene technology, human babies can be cloned. |
| D．Doctors can cure cancer and heart disease with the help of gene technology. |
What is the main purpose of writing this passage?
| A．Expressing the writer’s idea that gene technology will benefit people. |
| B．Telling people the disadvantages of gene technology. |
| C．Telling the readers that gene technology will not benefit people. |
| D．Explaining that gene technology will also do harm to the humanity. |
When the explorers first set foot upon the continent of North America, the skies and lands were alive with an astonishing variety of wildlife. Native Americans had taken care of these precious natural resources wisely. Unfortunately, it took the explorers and the settlers who followed only a few decades to decimatea large part of these resources. Millions of waterfowl ( 水禽 ) were killed at the hands of market hunters and a handful of overly ambitious sportsmen. Millions of acres of wetlands were dried to feed and house the ever-increasing populations, greatly reducing waterfowl habitat.
In 1934, with the passage of the Migratory Bird Hunting Stamp Act (Act), an increasingly concerned nation took firm action to stop the destruction of migratory ( 迁徙的) waterfowl and the wetlands so vital to their survival. Under this Act, all waterfowl hunters 16 years of age and over must annually purchase and carry a Federal Duck Stamp. The very first Federal Duck Stamp was designed by J.N. "Ding" Darling, a political cartoonist from Des Moines, lowa, who at that time was appointed by President Franklin Roosevelt as Director of the Bureau of Biological Survey. Hunters willingly pay the stamp price to ensure the survival of our natural resources.
About 98 cents of every duck stamp dollar goes directly into the Migratory Bird Conservation Fund to purchase wetlands and wildlife habitat for inclusion into the National Wildlife Refuge System - a fact that ensures this land will be protected and available for all generations to come. Since 1934, better than half a billion dollars has gone into that Fund to purchase more than 5 million acres of habitat. Little wonder the Federal Duck Stamp Program has been called one of the most successful conservation programs ever initiated.

By day, Robert Titterton is a lawyer. In his spare on stage beside pianist Maria Raspopova - not as a musician but as her page turner. "I'm not a trained musician, but I've learnt to read music so I can help Maria in her performance."
Mr Titterton is chairman of the Omega Ensemble but has been the group's official page turner for the past four years. His job is to sit beside the pianist and turn the pages of the score so the musician doesn't have to break the flow of sound by doing it themselves. He said he became just as nervous as those playing instruments on stage.
"A lot of skills are needed for the job. You have to make sure you don't turn two pages at once and make sure you find the repeats in the music when you have to go back to the right spot." Mr Titterton explained.
Being a page turner requires plenty of practice. Some pieces of music can go for 40 minutes and require up to 50 page turns, including back turns for repeat passages. Silent onstage communication is key, and each pianist has their own style of "nodding" to indicate a page turn which they need to practise with their page turner.
But like all performances, there are moments when things go wrong. "I was turning the page to get ready for the next page, but the draft wind from the turn caused the spare pages to fall off the stand," Mr Titterton said, "Luckily I was able to catch them and put them back."
Most page turners are piano students or up-and-coming concert pianists, although Ms Raspopova has once asked her husband to help her out on stage.
"My husband is the worst page turner," she laughed. "He's interested in the music, feeling every note, and I have to say: 'Turn, turn!' "Robert is the best page turner I've had in my entire life."

If you ever get the impression that your dog can"tell"whether you look content or annoyed, you may be onto something. Dogs may indeed be able to distinguish between happy and angry human faces, according to a new study.
Researcherstrained a group of 11 dogs to distinguish between images(图像) of the same person making either a happy or an angry face. During the training stage, each dog was shown only the upper half or the lower half of the person's face. The researchers then tested the dogs' ability to distinguish between human facial expressions by showing them the other half of the person's face or images totally different from the ones used in training .The researchers found that the dogs were able to pick the angry or happy face by touching a picture of it with their noses more often than one would expectby randomchance.
The study showed the animalshad figured out how to apply what they learned about human faces during training to new faces in the testing stage." Wecan rule out that the dogs simply distinguish between the pictures based on a simple cue, such as the sight of teeth,"said study author Corsin Muller." Instead,our results suggest that the successful dogs realized that a smiling mouth means the same thingas smiling eyes,and the same rule applies to an angry mouth having the same meaning as angry eyes."
"With our study, we think we can now confidently conclude that at least some dogs can distinguish human facial expressions,"Muller told Live Science.
At this point,it is not clear why dogs seem to be equipped with the ability to recognize
different facial expressions in humans."To us, the most likely explanation appears to be that the basis lies in their living with humans, which gives them a lot of exposure to human facial expressions," and this exposurehas provided them with many chances to learn to distinguish between them,Muller said.

We live in a town with three beaches.There are two parks less than 10 minutes'walk from
home where neighborhoodchildren gather to play.However,what my children want to do after school is pick up a screen-any screen- and stare at it for hours.They are not alone.Today'schildren spend an averageof four and a half hours a day looking at screens,split between watching television and using the Internet.
In the past few years, an increasing number of people and organisations have begun coming up with plans to counter this trend.A couple of years ago film-maker David Bond realised that his children,then aged five and three,were attached to screens to the point where he was able to say"chocolate" into his three-year-old son's ear without getting a response. He realised that something needed to change, and, being a London media type, appointed himself"marketing director fro Nature".He documented his journey as he set about treating nature as a brand to
be marketed to young people.The result was Project Wild T hing,a film which chartsthe birth
of the World Network,a group of organisations with the common goal of getting children out into nature.
"Just five more minutes outdoors can make a difference,"David Bond says."There is a lot of really interesting evidence which seems to be suggesting that if children are inspired up to the age of seven,then being outdoors will be a habit for life."His own children have got into the habit of playing outside now: "We just send them out into the garden and tell them not to come back in for a while."
Summer is upon us. There is an amazing world out there, and it needs our children as much as they need it.Let us get them out and let them play.
