Good Genes Mean Long Life
Scientists have discovered that living to the age of 100 may have nothing to do with the lifestyle you lead and everything to do with the type of genes you have.
For the lucky carriers of “Methuselah” genes, worries over smoking, eating unhealthily and not getting enough exercise may not be as necessary as to those of us without the special gene pattern (组合).
The “Methuselah” genes could give extra protection against the diseases of old age such as cancer and heart disease. They could also protect people against the effects of the unhealthy lifestyles that we believe will lead us to an early death, scientists say. However, the genes are very rare.
The genes include ADIPOQ, which is found in about 10 percent of young people but in nearly 30 percent of people living past 100. They also include the CETP and the ApoC3 genes, which are found in 10 percent of young people, but in about 20 percent of people over 100 years old.
Some of those genes were discovered by a research group at the Albert Einstein College of Medicine in New York, led by Professor Nir Barzilai. The team studied the genes of over 500 people over 100 years old, and their children.
The studies show that tiny mutations (变异) in the make-up of some genes can greatly increase a person’s lifespan (寿命). Barzilai told a Royal Society conference that the discovery of such genes gave scientists clear targets for developing drugs that could prevent age-related diseases, allow people to live longer and stay healthy.
David Gems, a researcher at University College London, believes that drugs to slow ageing will become widespread.
“If we know which genes control longevity (长寿) then we can … target them with drugs. That makes it possible to slow down ageing,” he told The Times.
“Much of the pain and suffering in the world are caused by ageing. If we can find a way to reduce that, then we are obliged (义不容辞的) to take it.”According to the article, which of the following is the most important if a person is to live to the age of 100?
| A．Eating healthy food every day. | B．Having the right types of genes. |
| C．Having a healthy lifestyle. | D．Taking drugs that prevent ageing. |
According to the article, the ApoC3 gene is found in ________ of people over 100 years old.
| A．10% | B．20% | C．30% | D．50% |
Which of the following statements is TRUE of the research led by Professor Nir Barzilai?
| A．The team studied the genes of over 100 people over 100 years of age. |
| B．The researchers found that mutations in certain genes lead to longer life. |
| C．The researchers found ways to develop drugs that could cure age-related diseases. |
| D．The study suggested that most people have genes that could lengthen their lives. |
According to David Gems, ________.
| A．drugs to slow ageing will be very expensive |
| B．modern science will be able to find more longevity genes |
| C．it is the duty of medical scientists to fight the problems of ageing |
| D．scientists can make new genes that will allow longer life |
We live in a digital world now, and a student's technology needs have changed. For the early years, say when you are in primary school, you can get by with no technology at all. Even if you have a computer, it's a good idea to get children familiar with libraries. At this age, trips to the library are like family outings.
As you get closer to middle school, a computer with Internet access becomes more of a necessity. Teachers will often give assignments that require a student to use the Internet for research. After a computer, technology choices for students become more difficult to make – especially when it comes to cell-phones. Kids will beg their parents for a cell-phone, especially in middle school. For many parents, it's a safety issue: They want to know that their kids can reach them quickly if necessary. For teachers, cell phones can be used to record lessons when students are absent. But many teachers dislike cell-phones. Some kids send messages or have talks in the class. Sending messages also raises the problem of cheating on exams. More and more schools are now forbidding the use of cell-phones.
Many kids see iPods as necessary things to have. iPods are great for music, but do they do anything good for your children’s education? Maybe they do. That’s the opinion of Doug Johnson, an educator for 30 years. Johnson says that educators should accept all new forms of technology in the classroom, including iPods. “Some do more with their cell- phones than we can do with our laptops,” he jokes. “I don’t think we should be afraid. The truth is that it’s easier to change the way we teach than to change the technology habits of an entire generation.”

[1] Look at the center circles of Diagram A and Diagram B. Which of the centre circles looks larger?
[2] Take a first look and you probably think that the centre circle in Diagram A is smaller than that in Diagram B. In fact, they are exactly the same size.
[3]Then look at the picture on the right.What do you see? A vase? Or two faces? Does the picture change quickly from one to the other again and again? Maybe or maybe not, but you can see them at the same time.
[4]“What’s happening? Is something wrong with my eyes?” You may wonder at what you see. Don’t worry. Here is how it goes:
[5]When we look at things, our eyes send messages to our brains and then our brains interpret (解释) the information. However, sometimes our brains interpret the received information in a wrong way. It seems that our eyes are playing a joke on us. This often happens and we call it “Visual illusion(幻觉)”.

Accidents happen almost daily. Some accidents are minor and some are serious but others may be fatal. We read about such accidents nearly every day in the newspapers. It is wrong for people to think that accidents occur only on the roads or highways, or even at worksites. Home accidents are just as common. Because very few home accidents are reported, people tend to think that there are few accidents which happen in homes.
There have been many cases where people fall to their deaths from high-rise flats. Children often fall from staircases while coming down the stairs. Old people may slip on wet or slippery floors if they are not careful.
Nowadays there are a lot of modern electrical appliances such as rice-cookers, electric irons, and kettles which make life easy for the modern housewives. These appliances can kill if they are not used in the proper way.
Gas stoves used for cooking are also dangerous if they are not properly handled. They may cause burns or, in more serious cases, they may even cause fires.
But all such accidents can be prevented if we are careful and obey simple rules of safety. For example, it is unwise for people to try repairing their own electrical appliances if they do not know how. It is safer for them to get their faulty appliances repaired by a qualified electrician.
61. Accidents take place_______.
A. mostly in homes B. mostly on roads and highways

A. People may fall to deaths from high buildings.
B. People may be knocked down by cars on the roads.
C. Gas stoves may caused burns or even fires.
D. People may get a shock from an electrical appliance
64. Which of the following is true about the modern electrical appliances?
A. They help modern housewives a lot.
B. They are very dangerous and should not be used.
C. They are usually safe unless they are used carefully.
D. They are not dangerous even if they are used carelessly.
65. People are advised________.

Many Chinese students who have learnt English for more than ten years are still unable to speak English very well when they meet a foreigner. They seem to have mastered the basic language structure (结构), but a conversation in English will make them feel uneasy. They are afraid that other people might find out their mistakes.
It’s uncommon that many students who are bad speakers of English can write English perfectly. This proves that they are unable to organize their idea in English. The center of the problem is that they lack practice and confidence.
Why should you be afraid? Do you fear those foreigners with whom you are speaking? Don’t be shy. They will not laugh at you just for a little mistake you make. The best way to get rid of trouble is to learn to speak by speaking more. I am sure that constant practice will help you succeed.
