To the world you may be one person, _______ to one person you may be the world．

A． and                B． however                C． so                 D． but

The world’s biggest Internet search engine, Google, has proven once again to be king of the Web. Users can download “Google Wi-Fi” software and then enjoy free Wi-Fi service available in some US cities since last Tuesday.

  Wi-Fi is short for “Wireless Fidelity”(无线上网). It allows laptop computers and personal digital assistants to connect to the Internet at high speed by radio sigal.

  A person with a Wi-Fi enabled computer can connect to the Internet when near one of the network’s access points. The place covered by one or several access points is called a hotspot. Google had already set up two “hotspots” in the US city of San Francisco which provide a free Wi-Fe service.

  The Wi- Fi technology even allows users to enjoy a free Internet phone service. Some scientists argue that Wi-Fi may replace mobile phone networks.

  Wi-Fi is stioo limited to a few cities, where there are “ hotspots”. But its capability(容量) of sending information has already done better than that of the mobile phone network, even that of 3G (Third Generation telecommunication technology). Some scientists have started to call Wi-Fi 4G.

  In addition to a high speed Internet connection, Fi-Fi has other advantages compared to mobile phones. We-Fi is global. The same Wi-Fi system works in different countries around the world. Different from using cell phones, you don’t need to change computers to use Internet phones when you go to other places and most importantly, many Internet phones cost you nothing at all.

Wi-Fi is not available in cities without_____.

 A. a computer   B. a radio   C. a hotspot   D. a cell phone

Which of the following is NOT the advantage of Wi-Fi?

The high speed Internet connection.   B. Many free Internet phones.

Using the same computers for Internet phones when you go to other places. C. Used in all the US cities.

Some scientists started to call Wi-Fi 4G, because_____.

A.it is the product of the Google”s 4^th generation.

B..it is more capable of sending information than the mobile phone network.

C.it has been used by more than four generations.

D.Wi-Fi will surely take the place of the mobile phone network.

. Which of the following is the best title?

A.Third Generation Telecommunication Technology

B. Free Call Service

C.Google Launches Free Wi-Fi Service

D.Free Wi-Fi Service across the U.S.A.

    Many of you may think healthy eating means you have to replace the foods you love with

those you don’t.

    The truth，though，is that keeping a healthy diet can be fun. Just ask Julie Upton，an ex-pert on nutrition and health in the US. Upton wants to advise teens everywhere to eat

healthier. She gives some suggestions on how to do just that.

    Q：What motivations should you keep in mind to eat healthy?

    A：I suggest setting goals for yourself. For example, it may be a goal to have one piece of fruit with lunch every day for a month, or to avoid eating fast food completely for the next month. Also focus on telling yourself，“What I eat now will affect how I look and feel a few

weeks from now，or how well I perform at school or in sports.”

    Q：What nutrients should teens consume every day？

    A：It depends on if you are a boy or a girl and how active you are. The best place to find

your ideal nutrient requirements is www. my pyramid. gov. Enter your gender（sex)，age and

activity level. It will tell you how many calories you need a day. It will also break that into

how many servings of each of the food groups those calories should come from.

    In general，most teens need about 2，500 to 3，500 calories every day.

    Q：What can teens do to make healthy snacking a fun habit？

    A：Teens are influential. Your good habits can influence lots of people, including your friend, younger sisters and brothers． You could  do challenges with friends about eating better. I think any way you can involve your friends，will help you succeed.

    Also get your family in on the health pleasure. If your parents do the food shopping， they have to know what to buy，so you need to tell them that you want healthier foods at home.

The common cold is the world's most widespread illness, which is plagues(疫病) that flesh receives.

     The most widespread fallacy(谬误) of all is that colds are caused by cold. They are not. They are caused by viruses passing on from person to person. You catch a cold by coming into contact, directly or indirectly, with someone who already has one. If cold causes colds, it would be reasonable to expect the Eskimos to suffer from them forever. But they do not. And in isolated Arctic regions explorers have reported being free from colds until coming into contact again with infected people from the outside world by way of packages and mail dropped from airplanes.

During the First World War soldiers who spent long periods in the trenches(战壕), cold and wet, showed no increased tendency to catch colds.

In the Second World War prisoners at the notorious Auschwitz Concentration Camp(奥斯维辛集中营), naked and starving, were astonished to find that they seldom had colds. At the Common Cold Research Unit in England, volunteers took part in Experiments in which they gave themselves to the discomforts of being cold and wet for long stretches of time. After taking hot baths, they put on bathing suits, allowed themselves to be with cold water, and then stood about dripping wet in drafty room. Some wore wet socks all day while others exercised in the rain until close to exhaustion. Not one of the volunteers came down with a cold unless a cold virus was actually dropped in his nose.

    If, then, cold and wet have nothing to do with catching colds, why are they more frequent in the winter? Despite the most pains-taking research, no one has yet found the answer. One explanation offered by scientists is that people tend to stay together indoors more in cold weather than at other times, and this makes it easier for cold viruses to be passed on.

No one has yet found a cure for the cold. There are drugs and pain suppressors(止痛片) such as aspirin, but all they do is relieve the symptoms.

Which of the following does not agree with the chosen passage?

   A. The Eskimos do not suffer from colds all the time.            

   B. Colds are not caused by cold.

   C. People suffer from colds just because they like to stay indoors.                      .  .

   D. A person may catch a cold by touching someone who already has one.

Arctic explorers may catch colds when       .

   A. they are working in the isolated arctic regions

   B. they are writing reports in terribly cold weather

   C. they are free from work in the isolated arctic regions

   D. they are coming into touch again with the outside world

Volunteers taking part in the experiments in the Common Cold Research Unit       .

   A. suffered a lot   B. never caught colds   C. often caught colds  D. became very strong

The passage mainly discusses       .

   A. the experiments on the common cold            B. the fallacy about the common cold

   C. the reason and the way people catch colds        D. the continued spread of common colds
