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 (基因) 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 .
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. 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 p
ossible 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 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 |
Marek was a farmer who lived in a village far away. One day he became very ill, and everyone thought he would die. They sent for a doctor, who arrived two days later and examined the sick man.

Too many people want others to be their friends, but they don’t give friendship back. That is why some friendships don’t last very long. To have a friend, you must learn to be one. You must learn to treat your friend the way you want your friend to treat you. Learning to be a good friend means learning three rules: be honest; be generous; be understanding.

Generosity means sharing and makes a friendship grow. You don’t have to give your ideas and feelings. These can be very valuable to friends. They tell your friends what is important to you. By sharing them you help your friend know you better.

Text messaging, or simply “texting”, which allows people to send and receive messages on mobile phones, becomes very popular today.
The advantages of texting are obvious. Texting helps to save money. If you have a few words to greet your families and friends on their birthdays or on some important festivals, sending messages can be cheaper than phone calling. Texting helps to save time. Even if you want to send a message to 100 people, you can do it one second. Texting helps you to “talk” to someone when he is too busy to answer the phone. Texting can also help you to “talk” to someone secretly if you don’t want others to hear what you are talking on the phone. These advantages are so amazing that many people are crazy about it. They hold mobile phones in hands all day long, send dozens of messages each day, and even text while driving or walking.
However, texting has its disadvantages. Junk（垃圾）messages may come into your mobile phone box now and then. When your phone box gets too full, you can’t receive any more messages. You may therefore miss some important information.
What’s more, if you don’t do texting properly, for example texting while driving or walking, it can be dangerous. It can cause injuries and even death. It is reported that about 6,000 people are killed and half a million were injured for this reason each year. In Fort Lee, a small town in New Jersey, USA, three people died because they walked into traffic while texting in 2011. Two researchers at Stony Brook University, New York found that texters are 60% more probably to have an accident than others. When people are texting, they don’t notice other people or things around them. To reduce traffic accidents, no drivers of the USA are now allowed to text while driving. About 32 countries have passed laws forbidding the use of mobile phones while driving.
Texting is a wonderful way of communication. However, only when we use it properly, can we fully enjoy the fun it brings.
