Have you ever wondered why different animals or pests have their particular colours? Colours in them seem to be used mainly to protect themselves．

       Birds, especially seagulls, are very fond of locusts, but birds cannot easily catch locusts because locusts change their colours together with the change of the colour of crops．When crops are green, locusts look green．But when crops are ripe, locusts take on exactly the same brown colour as crops have．Some other pests with different colours from plants are usually easily found and eaten by their enemies．So they have to hide themselves in terror for lives and appear only at night．

       If you study the animal life in any part of the world, you will find the main use of colouring is to protect themselves．Bears, wolves and other beasts move quietly through forests．They are usually invisible to the eyes of hunters, because they have the colour much like the barks of trees．

       An even more strange act remains to be noticed．A kind of fish living in seas can send out a kind of very black liquid when it faces danger．While the liquid spreads over, its enemies cannot find it, and it immediately swims away．Thus, it has existed up to now though it is not powerful at all．

1．This passage mainly talks about ________．

       A．the change of colour in locusts

       B．the protective coloration of animals and pests

       C．how a certain sea fish protects itself     

       D．a(chǎn)nimals or pests can dye themselves different colours

2．Locusts are ________ but they are not easily wiped out by their enemies because ________．

       A．a(chǎn)nimals; they are powerful enough  

       B．beasts; they are dangerous to their enemies

       C．pests; they take on the same colours as crops

       D．birds; they fly extraordinarily fast

3．The pests that have different colours from plants usually appear at night because ________．

       A．their enemies can easily find them and eat them

       B．they have the habit of coming out in darkness

       C．it’s easy for them to destroy plants in darkness

       D．birds take their rest when night comes

4．Bears and wolves have the same colour as barks of trees because ________．

       A．they fear other beasts

       B．they like brown or grey colours

       C．they enjoy walking through forests quietly

       D．the colours help prevent themselves from being noticed

I have been using the Internet since I was five years old, when my dad first sat me down in front of a computer and connected me the World Wide Web.

I’ve always felt like a master of the Internet world. AOL Instant Messaging, MSN, Gmail, Facebook, Myspace -- I’ve got it all under control. I thought there was nothing more to it besides checking my e-mail and wasting my time, until I was introduced to electronic commerce(e-commerce): business on the Internet.

Some online businesses are run from one-room home offices. Others have hundreds of employees (雇員) across the world. Have you ever heard of Amazon.com, Yahoo.com?

My friends often said they got cheap textbooks off Amazon.com, or had a good deal (交易) on Steve Madden shoes that were on sale at SteveMaden.com. Unfortunately for me, I continued my “e-commerceless” Web-surfing, not knowing about all the deals I was missing out on.

That is, of course, until my sister finally sold the idea to me.

“Why are all these packages arriving in the mail for you, Katy?” I asked her one day. Strange envelopes (信封) had been put on our doorstep for weeks now, each one always addressed to my sister; and we all know little sisters should never be getting more mail than their elders!

“Oh, it’s the things I ordered online!” she answered. I watched speechlessly as she opened them. There was no way our parents were letting her spend that much money- online or off!

“How much did all of this coat?”

“Oh, only about $15 in all!” She said excitedly. “Everything on eBay is on sale! It’s a way better than going to the mall.”

I felt as if there had been a store right in my backyard that I had never walked into! That week, I ordered a used Spanish textbook for my summer course online for 10 percent of the publishing price. A few days later, I bought an iPod protector and a book or two via the wonderful eBay.com.

1.From the first two paragraph we can conclude that the author        

A．had no experience using computers

B．had no idea of what e-commerce is

C．only used the Internet to check e-mail

D．thought surfing the Internet was a waste of time

2.The writer didn’t find out about e-commerce until       

A．he stopped web-surfing

B．he visited a store in his backyard

C．his sister explained the packages she got by mail

D．his friends told him about the online deals they made

3.We can infer from the last paragraph that the author       .

A．never enjoyed shopping that much

B．loves the big store in her backyard

C．feels she is a true master of the Internet

D．has begun to enjoy online shopping

4.What’s the purpose of the article?

A．To tell the readers how he begins online shopping.

B．To do business on the Internet.

C．To make an online shopping ad.

D．To advise people not to do online shopping

I was sure that I was to be killed. I became terribly nervous. I searched in my pockets to see if there were any cigarettes, which had escaped their search. I found one and because of my shaking hands, I could barely get it to my lips. But I had no matches, they had taken those. I looked through the bars at my jailer. He did not make eye contact with me. I called out to him, “Have you got a light?” He looked at me, shrugged and came over to light my cigarette. As he came close and lit the match, his eyes inadvertently(不經(jīng)意地) locked with mine. At that moment, I smiled. I don’t know why I did that. Perhaps it was nervousness, perhaps it was because, when you get very close, one to another, it is very hard not to smile. In any case, I smiled. In that instant, it was as though a spark jumped across the gap between our two hearts, our two human souls. I know he didn’t want to, but my smile leaped through the bars and generated a smile on his lips, too. He lit my cigarette but stayed near, looking at me directly in the eyes and continuing to smile.

I kept smiling at him, now aware of him as a person and not just a jailer. And his looking at me seemed to have a new dimension too. “Do you have kids?” he asked. “Yes, here, here.” I took out my wallet and nervously fumbled for the pictures of my family. He, too, took out the pictures of his family and began to talk about his plans and hopes for them. My eyes filled with tears. I said that I feared that I’d never see my family again, never have the chance to see them grow up. Tears came to his eyes, too. Suddenly, without another word, he unlocked my cell and silently led me out. Out of the jail, quietly and by back routes, out of the toxin. There, at the edge of town, he released me. And without another word, he turned back toward the town.

“My life was saved by a smile.” Yes, the smile -- the unaffected, unplanned, natural connection between people. I really believe that if that part of you and that part of me could recognize each other, we wouldn’t be enemies. We couldn’t have hate or envy or fear!

1. Why did the author smiled to the jailer first?

A. Because he wanted to make friends with the jailer.

B. Because he wanted to give a good impression on the jailer.

C. Because he wanted to share the cigarette with the jailer.

D. The reason was unknown to him and us.

2. Which of the following is the fight order according to the story?

a. I was set free at the edge of town.

b. I wanted to borrow a light from the jailer.

c. I was arrested and quite frightened.

d. I took out the pictures of my family.

e. The jailer took out the pictures of his family.

A. c, b, e, d, a     B. b, c, d, a, e            C. c, b, d, e, a            D. c, d, e, b, a

3. It can be inferred from the passage that ____________.

A. Before the author was released, he had stayed there for a long time.

B. Both of the author and the jailer loved their families very much.

C. The author had no chance to see his family again.

D. The jailer was punished by his leader at last.

4. What is the best title of the passage?

A. The use of smile                       B. Life in the jail.

C. The smile                                          D. Love is everywhere.

The films tell them the impossible is possible and that true love conquers all.
