   The idea of being able to walk on water has long interested humans greatly. Sadly, biological facts prevent us ever accomplishing such a thing without artificial aid---we simply weigh too much, and all our mass pushes down through our relatively small feet, resulting in a lot of pressure that makes us sink.

However, several types of animals can walk on water. One of the most interesting is the common basilisk Basilicus basilicus, a lizard (蜥蜴)native to Central and South America. It can run across water for a distance of several meters, avoiding getting wet by rapidly hitting the water’s surface with its feet. The lizard will take as many as 20 steps per second to keep moving forward. For humans to do this, we,d need huge feet that we could bring up to our ears in order to create adequate w hitting. ’’

But fortunately there is an alternative : cornflour. By adding enough of this common thickening agent to water (and it does take a lot), you can create a “non-Newtonian” liquid that doesn’t behave like normal water. Now, if the surface of the water is hit hard enough, particles(粒子)in the water group together for a moment to make the surface hard. Move quickly enough and put enough force into each step, and you really can walk across the surface of an adequately thick Liquid of cornflour.

Fun though all this may sound, it’s still rather messy and better read about in theory than carried out in practice. If you must do it, then keep the water wings handy in case you start to sink--and take a shower afterward!

【小题1】Walking on water hasn’t become a reality mainly because humans______.
A.are not interested in it
B.have biological limitations
C.have not invented proper tools
D.are afraid to make an attempt
【小题2】What do we know about Basilicus basilicus from the passage?
A.It is light enough to walk on water.
B.Its huge feet enable it to stay above water.
C.It can run across water at a certain speed.
D.Its unique skin keeps it from getting wet in water.
【小题3】What is the function of the cornflour according to the passage?
A.To create a thick liquid.
B.To turn the water into solid.
C.To help the liquid behave normally.
D.To enable the water to move rapidly.
【小题4】What is the author’s attitude toward the idea of humans’ walking on water?
A.It is risky but beneficial.
B.It is interesting and worth trying.
C.It is crazy and cannot become a reality.
D.It is impractical though theoretically possible.

What is the first thing you notice when you walk into a shop? The products displayed (展示) at the entrance? Or the soft background music?
But have you ever notice the smell? Unless it is bad, the answer is likely to be no. But while a shop’s scent may not be outstanding compared with sights and sounds, it is certainly there. And it is providing to be an increasing powerful tool in encouraging people to purchase.
A brand store has become famous for its distinctive scent which floats through the fairly dark hall and out to the entrance, via scent machines. A smell may be attractive but it may not just be used for freshening air. One sports goods company once reported that when it first introduced scent into its stores, customers’ intension to purchase increased by 80 percent.
When it comes to the best shopping streets in Pairs, scent is just as important to a brand’s success as the quality of its window displays and goods on sales. That is mainly because shopping is a very different experience to what it used to be.
Some years ago, the focus for brand name shopping was on a few people with sales assistants’ disproving attitude and don’t-touch-what-you-can’t-afford displays. Now the rise of electronic commerce (e-commerce) has opened up famous brands to a wider audience. But while e-shops can use sights and sounds, only bricks-and-mortar stores (实体店) can offer a full experience from the minute customers step through the door to the moment they leave. Another brand store seeks to be much more than a shop, but rather a destination. And scent is just one way to achieve this.
Now a famous store uses complex man-made smell to make sure that the soft scent of baby powder floats through the kid department, and coconut (椰子) scent in the swimsuit section. A department store has even opened a new lab, inviting customers on a journey into the store’s windows to smell books, pots and drawers, in search of their perfect scent.
【小题1】According to the passage, what is an increasingly powerful tool in the success of some brand store?
A.Friendly assistant.B.Unique scents.
C.Soft background music.D.Attractive window display.
【小题2】E-shops are mentioned in the passage to ______.
A.show the advantages of brick-and-mortar stores
B.urge shop assistants to change their attitude
C.push stores to use sights and sounds
D.introduce the rise of e-commerce
【小题3】The underlined word “destination” in Paragraph 5 means ______.
A.a platform that exhibits goods
B.a spot where travelers like to stay
C.a place where customers love to go
D.a target that a store expects to meet
【小题4】The main purpose of the passage is to ______.
A.compare and evaluateB.examine and assess
C.argue and discussD.inform and explain

   Before I studied psychology,I used to think that people would laugh when funny things occurred. While I was right about that,I discovered there are lots of other psychological reasons that make people laugh other than the funny part of a joke. When someone laughs at a joke,there will usually be more than one reason that makes him laugh-and the more reasons there are,the more powerful the joke will be.

I was attending a stand-up comedy show in Egypt,and when the man started to make fun of pedestrians crossing streets,everyone laughed their head off. The main reason why those people strongly laughed was that almost all of them felt angry with pedestrians who crossed streets carelessly. The joke wasn't only funny,it also made the audience feel that they were right about being angry at those pedestrians. That is,people were laughing because of both the funny joke and the happiness experienced as a result of the psychological support they got.

The better a joke makes a person feel,the more it includes other psychological factors,and the more the person will like it. For example,if you envy one of your friends,and someone tells a joke that is funny and,at the same time,makes your friend seem stupid,then you will probably laugh at it louder than if you weren't jealous(嫉妒的)of him.

In short, we not only laugh when we hear something funny, but also laugh when we experience some kind of happiness that results from the other psychological factors involved in the joke. I strongly discourage making fun of anyone or belittling someone to make someone else laugh. All I want to explain is that if your joke supports a person's emotions, he will certainly like it a lot.

【小题1】What did the author find out after studying psychology?
A.Only good jokes make people laugh.
B.Many reasons lead to people laughing.
C.Funny things can make people laugh.
D.Laughter can make people healthy.
【小题2】Why did the audience laugh at the pedestrians?
A.Because they played a trick on the pedestrians.
B.Because the pedestrians behaved in a funny way.
C.Because they could feel the pedestrians' happiness.
D.Because their emotions were approved of by the show.
【小题3】What does the underlined word "belittling" probably mean?
A.Speaking highly of.B.Getting close to.
C.Looking down on.D.Feeling content with.

Satellites(卫星) are an important part of our ordinary lives.For example, the information for weather forecasts is sent by satellite.Some satellites have cameras which take photographs of the Earth to show how clouds are moving.Satellites are also used to connect our international phone calls.
Computer connections of the World Wide Web and Internet also use satellites. Many of our TV programs come to us through satellites.Airplane pilots also sometimes use a satellite to help them find their exact location.
We use satellites to send television pictures from one part of the world to another.They are usually 35,880 kilometers above the equator(赤道).Sometimes we can see a satellite in the sky and it seems to stay in the same place.This is because it is moving around the world at 11,000 kilometers an hour—exactly the same speed that the earth rotates.A satellite must orbit the Earth with its antennae(天线)facing the earth.Sometimes, it moves away from its orbit(轨道),So there are little rockets on it which are used to put the satellite back in the right position.This usually happens about every five or six days.
Space is not empty! Every week, more and more satellites are sent into space to orbit the Earth.A satellite usually works for about 10-12 years.Satellites which are broken are sometimes repaired by astronauts or sometimes brought back to Earth to be repaired.Often,very old or broken satellites are left in space to orbit the Earth for a very long time.This is very serious because some satellites use nuclear power and they can crash(撞)into each other.
【小题1】Which of the following is NOT done by satellites according to the passage?
A.Sending information for weather forecast.
B.Taking photographs of the Earth.
C.Sending TV pictures.
D.Providing food for airplane pilots.
【小题2】What’s the speed the earth rotates at?
A.35,880 kilometers per hour.
B.335,880 kilometers per hour.

D.110,000 kilometers per hour
【小题3】Why does the satellite move around the world at the same speed as the Earth rotates?
A.In order to take photographs.
B.In order to stay in a certain position in the orbit.
C.In order to move away from its orbit.
D.In order to send television pictures.
