The surprising experiment I am about to describe proves that air is all around you and that it proves down upon you. Air pressure is a wonderful force. When you swim underwater, you can feel water push down your body. The air all around you does the same. However, your body is so used to it that you do not notice this. The pressure is caused by a layer of air called the atmosphere. This layer surrounds the Earth, extending to about five kilometers above the Earth’s surface.

The following experiment is an easy one that you can do at home. But make sure that you are supervised, because you will need to use matches. Now foe the experiment!

    What you need

    ·A hard-boiled egg without the shell

    ·A bottle with a neck slightly smaller than the egg

·A piece of paper

·A match

Metheod

1) Check that the paper will sit firmly on the neck of the bottle.

2) Tear the paper into strips and put the strips into the bottle.

3) Light the paper by dropping a burning match into the bottle.

4) Quickly sit the egg on the neck of the bottle.

Result

  Astonishingly, the egg will be sucked into the bottle. Your friends will be amazed when you show them the experiment. But be careful when you handle matches.

Why it happened

As the paper burns, it needs oxygen and uses up the oxygen (air) in the bottle. The egg acts as a seal in the neck of the bottle, so no more air can get inside. This reduces the air pressure inside the bottle. The air pressure must equalize, so more air from outside must enter the bottle. The outside air pressure against the egg and then the egg is pushed into the bottle! The proves that air is all around and that it is pressing down on it.

64.Why is there the need to take care when you are doing the experiment?

       A.The bottle could break.

       B.You need to light the paper with a match.

       B.make a seal in the neck of the bottle

       C.finish up the oxygen inside the bottle

       D.produce more oxygen inside the bottle

66.How did the egg put into the bottle?

       A.The oxygen inside the bottle sucked the egg in.

       B.It became salt without the shell.

       C.The neck of the bottle was wide enough.

       D.The outside air pressure forced it into the bottle.

    “Congratulations, Mr. Jones, it’s a girl.”

    Fatherhood is going to have a different meaning and bring forth a different answer from every

Man who hears these words. Some feel proud when they receive the news, while others worry, wondering whether they will be good fathers.Although there are some men who like children and may have had considerable experience with them, others do not particularly care for children and spend little time with them.Many fathers and mothers have been planning and looking forward to children for some time.For other couples, pregnancy was an accident that both husband and wife have accepted willingly or unwillingly.

Whatever the reaction to the birth of a child, it is obvious that the shift from the role of husband to that of father is a difficult task.Yet, unfortunately, few attempts have been made to educate fathers in this remobilization process.Although numerous books have been written about American mothers, only recently has literature focused on the role of a father.

It is argued by some writers that the transition to the father‘s role, although difficult, is not nearly as great as the transition the wife must make to the mother‘s role.The mother‘s role seems to require complete transformation in daily routine and highly innovative adaptation; on the other hand, the fathers role is less demanding and immediate.However, even though we mentioned the fact that growing number of women are working outside the home, the father is still thought by many as the breadwinner in the household.

1.According to the author,being a father_________.

        A.brings a feeling of excitement to some men

        B.has a different meaning for those who have daughters

        C.makes some men feel proud and others uneasy

        D.means nothing but more responsibilities

2.It is stated in the passage that__________.

        A.some parents are not prepared to have a child

        B.young couples do not like children at all

        C.do not have much time to take care of their children

        D.many parents look forward to having a boy as their first child

3.The transition to the mother‘s role requires that the wife__________.

        A.change her lifestyle in a highly innovative way

        B.make a complete change in her everyday life to deal with the new situation

        C.stay at home to take care of the baby

        D.help her husband in his remobilization process

4.Some writers argue that with respect to the change of roles, fathers, compared with mothers, ___________.

        A.have to shoulder more burdens

        B.have to make more difficult adaptations

        C.have an easier job to do

        D.can usually do a better job

World Wrestling Entertainment is the largest professional wrestling organization in North America. It was called World Wrestling Federation until it changed its name because of a legal dispute. Its more than one hundred wrestlers fight each other in competitive matches that are written and practiced before they are performed.

Professional wrestlers are athletes but act as entertainers. They are not seeking athletic records, but instead want to excite an audience. To do this, they use unusual names and wear special clothing during wrestling matches. These wrestlers include the Stone Cold Stunner and the Undertaker.

Most professional wrestling matches are between two men or two women. They fight inside an area called a ring that is separated from the audience by ropes. Each match continues until one wrestler forces the other's shoulders to the floor and holds them there for a count of three. Most World Wrestling Entertainment matches continue for only about four to seven minutes.

An organization official called a promoter decides before the match who will win. But who wins and who loses is not the important thing in professional wrestling. The important thing is that the audience enjoys the pretend fight. Some wrestlers rarely win, but continue to be popular.

Not all wrestling matches are between two people. Some are called tag team matches and involve teams of two, three or four wrestlers. Another kind of match is called a battle royal. It involves thirty to sixty wrestlers competing against each other. A wrestler loses when he or she is thrown out of the ring. The winner is the last wrestler still standing.

1.Why did World Wrestling Federation change its name?

A.Because audience didn’t like it.

B.Because maybe there was another name similar to it.

C.Because they wanted their name more unusual.

D.Because the name was out of date.

Hey there,

So you’re about to spend four years of your life and tens of thousands of dollars of your patent’s money, and all you really know about college is that all of your friends are going. Do you ever stop to wonder why you’re going?

Relax. You’re making the right decision. First of all, you’ll discover what interests you by taking courses in many subjects. For example, it’s hard to decide if you want to be a painter if you’ve never painted any picture; once you’re in a drawing-room on campus, you’ll know one way or the other. College is also a lot of fun — after you graduate, you’ll be working every weekday for 50 or so years. And remember that college graduates earn about twice the income of those who never attended college.

Finding the right college can be difficult. Fortunately, Johnson Review is here to help you every step of the way.

*Researching Schools. To us, the most important decision you’ll make is to choose the school that really fits you best — not the one that is the most competitive (有竞争力的) or has the best-equipped rooms.

*Applying to School. On JohnsonReview.com , you’ll find hundreds of actual college applications(申请)and links to many more .

*Raising Your Scores.  American College Test is one of the most difficult parts of the admissions (录取) course . It’s nor the most important, though, and not everyone needs to prepare for the test. But, if you think you can do better, find the right course for better scores.

*Paying for School. Most families need financial aid for the high cost of college. The problem is that financial aid seems difficult to get and many families get caught up in the price of college rather than learning the ways to get financial aid . If you really do your research, you’ll learn that you can afford to attend any college, no matter the cost. For more information, call 600-3681 or visit JohnsonReview.com. Wherever you go, have a nice trip!
