As we know, DNA testing is very useful for crime fighting. But now crime fighters could have a new tool at hand. Researchers have developed a cutting-edge (前沿的) technique to identify human hair. Their test is quicker than DNA analysis techniques currently used by the police.

DNA testing is commonly used for identification because DNA is unique to each individual. However, environmental and chemical processes can degrade(降解) DNA, limiting its usefulness over time. Protein (蛋白质) in hair, on the other hand, is more stable than DNA but can also have variations (变异体) that may be unique to the individual.

“Our analysis process can be used universally, ”says Ms. Huang, “One of our samples even included dyed hair and the test was 100 per cent accurate. The test was able to distinguish East Asians, Caucasians and South Asians.”

Dr. Beauchemin says she has got in touch with law enforcement agencies about using the new technology. She is also planning to collect more hair samples and continue her research with a goal of finding where exactly in the world hair sample is from, to look for more races and determine specific age.

“We are in a very similar place with protein-based identification to where DNA testing was during the early days of development,” said chemist Brad Hart. “This method will be a game-changer, and while we’ve made a lot of progress toward improving it, there are steps to go before this new technique is able to reach its full potential.”

1.What’s the main purpose of the text?

A. To analyze crime scenes.

B. To distinguish different races.

C. To show the usefulness of DNA testing.

D. To introduce a new identification method.

2.Which will be the most useful in identifying a person according to Brad Hart?

A. Chemical materials.　　 B. Protein in hair.

C. DNA variations.　　 D. Blood sample.

3.What’s the advantage of the protein-based identification over DNA testing?

A. Stability.　　 B. Popularity.

C. Security.　　 D. Convenience.

4.What can be inferred from the last paragraph of the text?

A. DNA testing will soon reach its full potential.

B. Protein-based identification remains to be improved.

C. Protein-based identification has replaced DNA testing.

D. DNA testing develops as rapidly as protein-based identification.

We live in a dangerous world. The figures for crime go up year by year. If you were attacked in the street, would you be able to defend yourself? Not very well probably, especially if someone was pointing a gun at you. We all see a lot of violence of films, but recently some programs on television showed how people can defend themselves without guns. For example, in one film a woman was attacked from behind. She threw the man, who was heavier and stronger than she was, over her head. Then she held him tightly on the ground. How? She knew Judo.

Jiu-jitsu, as judo is sometimes called, means "muscle science" in Japanese. The student of judo needs to learn a lot about the body, its bones and muscles. Judo uses a number of "falls", "holds" and "throws". Someone who does not know judo cannot defend himself against them. If you know judo you can defend yourself against a person who is stronger than you. You had better not practice judo on your friends unless they can fall without hurting themselves! Being strong is one thing, but using the body wisely is another. In judo, you use the other person's body to help you. You "throw" him to the ground and "hold" him there, so that he cannot move. Of course, it takes time and practice, but knowing judo is useful. In a violent world you ought to be able to defend yourself.

1.According to passage, in fact "judo" is ______.

A．the same as "Jiu-jitsu"                    B．a kind of fighting

C． a kind of muscle science                 D．is helpful to a strong man

2.Why does the writer say the world is dangerous?

A． The number of violence and crime is increasing every year.

B．Because many people carry guns.

C．Because there too many films.

D．Because people are not able to defend themselves.

3.Which of the following statement is true about the woman in the passage?

A．The woman held the man over her head.

B．The woman was heavier than the man.

C．The woman was able to defend herself.

D．The woman attacked the man from behind.

4.If a man knows judo, he ______.

A．will be good at muscle science.

B．will be able to avoid being attacked from his back.

C．may defeat any strong person.

D．can help himself by using the other person's body

5.What's the best title for this short passage?

The following is something about extreme sports: Dangerous as they are, extreme sports remain appealing among many Australian young people! Camp extreme sports is the perfect test of your heart.

Kite Surfing

It’s the exciting mixture of kite, board and waves. The idea of using a kite to accelerate speed seems like a new challenge, yet the art of kite flying dates back to the 13th-century Chinese when it was used as a simple means of transport.

Catch a wind and you’re moving — up, down and across the surf. “It’s always exciting. You’d jump 5 feet or 35 feet. You never know if you’re going to go up in the air, and your heart is just going boom, boom, boom.”

Coasteering

It is by far the best activity and the event that everyone is still talking about. This is exploring the coastline without worrying about a coastal path or finding a rocky bay blocking your route. You climb, dive and swim from one place to another. With Coasteering, you don’t have to be able to swim as the wet suit and buoyancy(浮力) aid will keep you floating when you are in the water.

Sky Diving

Traditional parachuting(跳伞) doesn’t sound risky enough. So now sky diving is the name for jumping from a plane and listening to your heart beating heavily as you move fast towards earth before you open your parachute at the last moment.

Mountain Biking

It’s been around so long that bikers are no longer satisfied with just going up and down a mountain. Mountain biking is a sport which consists of riding bicycles off-road, often over rough land, using specially adapted mountain bikes. Mountain bikes share similarities with other bikes, but include features designed to improve strength and performance in rough areas.
