The first breath-taking pictures of the Earth taken from space showed it as a solid ball covered by brown land masses and blue-green oceans. We had never seen the Earth from that distance before. To us, it appeared as though the Earth had always looked that way and always would. Scientists now know, however, that the surface of the Earth is not as permanent as we had thought.
Scientists explain that the surface of our planet is always moving. Continents moves about the Earth like huge ships at sea. They float on pieces of the Earth’s outer skin. New outer skin is created as melted rock pushed up from below the ocean floor. Old outer skin is destroyed as it rolls down into the hot area and melts again.
Only since the 1960s have scientists really began to understand that the planet Earth is a great living machine. Some experts have said this new understanding is one of the most important revolutions in scientific thought. The revolution is based on the work of scientists who study the movement of the continents—a science called plate tectonics.
The modern story of plate tectonics begins with the German scientist Alfred Wegener. Before World War One, Wegener argued that the continents had moved and were still moving. He said the idea first occurred to him when he observed that the coastlines of South America and Africa could fit together like two pieces of a puzzle. He proposed that the two continents might have been one and then split apart.
Wegener was not the first person to wonder about the shape of the continents. About 500 years ago, explorers thought about it when they made the first maps of Americas. The explorers noted the east coast of North America and South America would fit almost exactly into the west coast of Europe and South Africa. What the explorers did not do, but Wegener did, was to investigate the idea that the continents move.

Nothing can spoil a vacation quicker than losing your money or credit cards. A few simple steps before you head out of the door can help protect your cash, card and personal information while you’re traveling.
Paul Stephens, a policy analyst San Diego, notes that people spend a lot of time planning their trips, from buying guidebooks to finding just the right beach outfits(裝備).“But their eyes glaze(呆滯) over when the subject of keeping money safe comes up,” he said.
“Why not take a few minutes to do something that could probably save your vacation?” Stephens asked.“In most cases, they can go on your to-do list with‘ buy travel bags’ and everything else,” he added.
The top recommendation is to clean your wallet. Remove unnecessary credit cards and any other unneeded documents that could compromise(危及...的安全)your identity if lost or stolen while you’re on vocation.
Then make a photocopy of the cards you’ve decided to take along and keep it in a secure location with you(not in your wallet)or leave it with a trusted relative or friend back home. Then you will know who you need to contact and how to reach it if your wallet is missing.
“Travelers should never leave their wallets or any identifying documents in their hotel room when they’re not there,” he said.” Choose a hotel with a safe to keep your valuable things in. Or keep your wallet and documents with you at all times. ”

An Experiment
Materials: Newspaper, ‘ACE’ hardware ruler (1/8 “think”), a flat table.
Purposes: We’ll show that there is air pressure pushing on us, from every direction while we’re on this Earth.


 
Procedure:

First put a thin ruler on a flat table with a little
less than half of it hanging off the edge of the table
(see the drawing below). Next place a sheet of newspaper
over the ruler flat against the table. Make sure to have
as little air as possible under the paper so that the fold line of the newspaper is at the ruler. Then quickly strike the end of the ruler hanging off the edge of the table. If you strike it quick enough, the ruler will break near the table edge.
What’s going on?
The Earth is covered in a layer of air that is nearly 80 miles thick and at sea level (the bottom) exerts or ‘pushes’ hard almost 15 pounds of pressure per square inch. That means that a full sheet of newspaper laid out flat has nearly 9,300 pounds of air above it.
When you break the ruler above, you are able to break it because of the 'heavy' air pushing down on the paper while you quickly strike the ruler. At first the table is pushing back on the paper, and if you move the ruler quick enough, other air around the edges of the paper can't get under the paper fast enough, so you are trying to lift that 9,300 pounds with the ruler! Some air gets under the paper, but not enough, so the ruler breaks.
1.By doing the experiment, we may realize         .
A.that air exits everywhere
B.why there are directions
C.that we live with air pressure
D.how air helps on the earth
2.How many steps are there in this experiment?          .
A.2      B.3       C.4       D.5
3.The underlined word “exert” probably means       .
A.cover completely            B.a(chǎn)dvocate actively    
C.influence gradually  D.press heavily
4.The ruler breaks under a quick strike mainly because of          .
A.the air pressure on the newspaper   B.the heavy weight of the newspaper
C.the heavy weight of the flat table    D.the strong power used on the ruler

NOT all memories are sweet. Some people spend all their lives trying to forget bad experiences. Violence and traffic accidents can leave people with terrible physical and emotional scars. Often they relive these experiences in nightmares.
Now American researchers think they are close to developing a pill, which will help people forget bad memories. The pill is designed to be taken immediately after a frightening experience. They hope it might reduce ,or possibly erase(抹去),the effect of painful memories.
In November, experts tested a drug on people in the US and France. The drug stops the body releasing chemicals that fix memories in the brain. So far the research has suggested that only the emotional effects of memories may be reduced, not that the memories are erased.
The research has caused a great deal of argument. Some think it is a bad idea, While others support it.
Supporters say it could lead to pills that prevent or treat soldiers' troubling memories after war. They say that there are many people who suffer from terrible memories.
"Some memories can ruin people's lives . They come back to you when you don't want to have them in a daydream or nightmare. They usually come with very painful emotions," said Roger Pitman, a professor of psychiatry at Harvard Medical School. "This could relieve a lot of that suffering."
But those who are against the research say that changing memories is very dangerous because memories give us our identity (特質(zhì)). They also help us all avoid the mistakes of the past.
"All of us can think of bad events in our lives that were horrible at the time but make us who we are. I'm not sure we want to wipe those memories out, "said Rebecca Dresser, a medical ethicist.
1. The passage is mainly about_____________.
A. a new medical invention          B. a new research on the pill
C. a way of erasing painful memories  D. an argument about the research on the pill
2. The drug tested on people can_____________.
A. cause the brain to fix memories
B. stop people remembering bad experiences
C. prevent body producing certain chemicals
D. Wipe out the emotional effects of memories
3. We can infer from the passage that_____________.
A. people doubt the effects of the pills
B. the pill will stop people's bad experiences
C. taking the pill will do harm to people's health
D. the pill has probably been produced in America
4. Which of the following does Rebecca Dresser agree with?
A. Some memories can ruin people's lives.
B. People want to get rid of bad memories.
C. Experiencing bad events makes us different from others.
D. The pill will reduce people's sufferings from bad memories.

Well, Mrs. Evans, I’ve done my best to look after David. I’ve tidied his room up every day, got him a meal together whenever he needed one and made sure he’s always had a clean shirt to put on. It’s not been easy, with two of my own to worry about, as well. David had the best of attention, I must say. But now because I asked him to give up bringing that American friend to his home he has got quite miserable and unfriendly.

It might be a good idea to take him out for a meal, perhaps even with his friend. I don’t know whether it will do any good but we can try.
