  There are three reasons why I don't think that we are ready for cloning.

  Firstly,we don't know exactly what the consequences of cloning would be. For example,if scientists cloned a man,they might know what he would look like,but they wouldn't know his dominant traits. What would happen if scientists cloned another Hitler or others like him? Do you really think we would survive if this became a reality?

  Secondly,cloning raises many ethical questions. Look back at the cloned man I presented and ask yourself these questions ：

  "Do you really think that he would be a man?"

  "Who would be responsible for him?"

  "Do you think he should have the same rights as we have?" I don't think that we can answer these questions now.

  Lastly,we don't know exactly what the meaning of life is. In my opinion,creating life is the duty of nature,and we must not interfere with that task be?cause we can't understand the extremely complicated relationships among lives that are defined by nature. Usually these relationships are extremely complex. Sometimes,they seem to be so untouchable that they cannot be changed. From my point of view,we have to look at the natural environment around us. We can see that an ecosystem (生态系统) is composed of a lot of different kinds of life,and each life has its own function within the system. If we inter?fere with that,I think it could lead to our extinction.

  Even though cloning may have a lot of benefits for humans,I think we should stop cloning because we do not understand it and can't control all of its effects. Maybe in future,we will be ready to do it,but that time has not yet arrived.

  The Internet company Google is testing its newest high-tech device,Google Glass. The company describes the glasses as wearable computers that would change the way people view others and the world.

  The glasses have a tiny video screen and a camera that connect wirelessly to the Internet through Wi-Fi,a smart phone,or a table computer. You can make and receive calls,send and receive texts,take pictures,record videos or search the Web. You control Google Glass using your voice,and a touch pad on the right arm of the frame.

Professor Marcia Dawkins is among a selected group of people who have been given a chance to test out Google Glass.

  The Professor's Google Glass looks like a bright orange glasses,without the actual glass. But there's a tiny rectangular glass at the top right-hand cor?ner. Through that glass,she has been recording videos while biking. She al?so has been able to talk to her sister inThailand, and she plans to use the de?vice to teach a public speaking class. But not everyone is excited about Google Glass. Some are concerned about possible risks to privacy. John Simpson is the director of the privacy project at Consumer Watchdog.

"It is essentially going to allow people to come in and spy on you and record that,without you knowing what is going on."

  Google says that it has already addressed that concern. Chris Dale,who is the Senior Manager of Communications for Google Glass,explained that in order to start the camera or record a video,the owner must say something out loud.

But film-maker Chris Barrett showed just how easy it is to record people without them knowing it. His glass captured a man getting arrested after a fight. He shared the video on YouTube.

  Also,some are concerned about the use of facial recognition technology on Google Glass. But Google says it will not approve the use of such applica?tions. The Internet company says it is still testing its new device,and it hopes to make Google Glass available to the public by early next year.

1. According to the passage,how can the users control Google Glass?

   A. By connecting to the Internet through Wi-Fi.

   B. By using a smart phone or a tablet computer.

   C. By using their voice and a touch pad on the frame.

   D. By changing the direction of Google Glass.

2. About Google Glass,which of the following is NOT true?

   C. It can be used to record videos or search the Web.

   D. It can be used to call and receive calls,send and receive texts.

3. It can be inferred from the passage that        .

   A. Google Glass makes all the people excited

   B. Google has solved the shortcomings of Google Glass

   C. Google Glass might reveal people's privacy

   D. Google Glass has been on the market

4. Why was film-maker Chris Barrett mentioned in the passage?

   A. To demonstrate he is a famous film-maker.

   B. To prove Google Glass easily reveals privacy.

   C. To show how to record people by Google Glass.

   D. To share some latest information about Google Glass.
