A rainforest is an area covered by tall trees with the total high rainfall spreading quite equally through the year and the temperature rarely dipping below 16℃.Rainforests have a great effect on the world environment because they can take in heat from the sun and adjust the climate. Without the forest cover, these areas would reflect more heat into the atmosphere，warming the rest of the world. Losing the rainforests may also influence wind and rainfall patterns, potentially causing certain natural disasters all over the world.
In the past hundred years, humans have begun destroying rainforests in search of three major resources (资源): land for crops, wood for paper and other products, land for raising farm animals. This action affects the environment as a whole. For example，a lot of carbon dioxide(二氧化碳)in the air comes from burning the rainforests. People obviously have a need for the resources we gain from cutting trees but we will suffer much more than we will benefit.
There are two main reasons for this. Firstly, when people cut down trees, generally they can only use the land for a year or two. Secondly, cutting large sections of rainforests may provide a good supply of wood right now, but in the long run it actually reduces the world’ s wood supply.
Rainforests are often called the world’s drug store. More than 25% of the medicines we use today come from plants in rainforests. However, fewer than 1% of rainforest plants have been examined for their medical value. It is extremely likely that our best chance to cure diseases lies somewhere in the world’s shrinking rainforests.Why did humans destroy rainforests in the past hundred years?

My grandmother seems to be wrong when she says that good manners will never go out of style.
Several days ago, I tried entering a lift with one of my arms fixed in a bandage(绷带) while carrying a computer bag in the other. Not being fast enough, I was passed by two young people who managed to get into the lift before me. The lift door closed only after I entered. Having already pressed their wanted floor button, the young people waited impatiently for me to press the button for where I was going. If they had decided to help, we could have moved much faster. But they had not. So I did my best and pressed the button with my arm. The two young people looked very angry with me. I was losing heart.
The memory of this incident has stayed with me because it followed shortly after my building’s watchman refused to help me carry a heavy box full of books. His answer was that he could not carry the books a few meters because it was not his job. However, I remembered myself helping people for so many years carrying boxes, shopping bags, or pushing wheelchairs upon the request of a stranger in need or when my conscience(良心) called on me. "Oh, this young generation, they have no manners, ”my grandmother would say. The idea of good manners refers to the considering of other people’s feelings. We need more and more people to have good manners. Good manners should be-come part of our lives. The author believes that ________.
| A．good manners will never go out of style |

Among the many differences between Western and Chinese cultures, table manners are one of the most noticeable(显著的) differences. Westerners often make mistakes at the table in China or in a Chinese home. In order not to have an embarrassing（尴尬的） experience, here are some things to consider next time you are eating with some Chinese.
Step1:
Keep in mind that food is shared. It is one of the biggest differences between Chinese and Western eating habits. In China a few dishes are placed in the center of a table and shared by all. Also, you should offer thanks when a Chinese host takes food from one of the dishes on the table and places it on your plate. Refusing it would not be polite even if you are full.
Step2:
Respect the chopsticks. The chopsticks are the single most important tool at a Chinese table. Use the chopsticks to grab food and never skewer (叉) it. Also make sure to place your chopsticks over your bowl or plate. Don’t lay them on the table or even worse, stick them into the rice bowl.
Step3:
Use communal(共用的)chopsticks. To take food from the center of the table you should use the communal chopsticks or spoons that are placed there for that purpose. If there are no communal tools, use the other ends of your chopsticks to take food, remembering not to use the other end to put food into your mouth.
Step4:
Respect the elders. Table manners in China place extra respect on elders. At the table, pass food to your elders before taking it for yourself. If someone makes a toast, make sure that when you clink glasses with someone older than you, the rim of your glass is lower than the rim of the elder person.How can you use your chopsticks according to the passage?
| A．Use them to grab your own food. |
| B．Put them on the table. |
| C．Use them to skewer the food. |
| D．Stick them into the rice bowl. |
According to the passage, the following are wrong EXCEPT that ________.
| A．you don’t have to accept the food a Chinese host places on your plate |
| B．a skewer is also a commonly used tool at a Chinese table |
| C．one can offer his own chopsticks for communal use when there aren’t any |
| D．when clinking glasses, the rim of the younger person should be lower than that of the older person |
What is the purpose of writing the passage?
| A．To let the world get a full understanding of China. |
| B．To introduce table manners among different cultures. |
| C．To introduce Chinese table manners to Westerners. |
| D．To introduce how Chinese table manners came into being. |
I want to tell you a story that changed my life many years ago. We were living in College Station, Texas and my wife and I were on our way home from Houston, Texas one Saturday morning. We decided to stop at a local restaurant to get something to eat since we had enough time. When we finished, we got back into our car and before I started it, we noticed a homeless man standing in front of the building. His clothes were worn and it looked as though he didn’t have any money. It was cold and I was sure he wanted something warm to drink; however, it was not this that I remember, because that is not what "moved" me. A dog was also walking up to the front of the building. Being a dog owner, I knew that the dog was a mother, and that she had just had some pups (小狗). She was hungry and weak and I felt bad for her. I knew if she didn’t eat soon, she and her pups would not live. People walking by didn’t even notice her. She was not as pretty and clean as most dogs, but she still deserved (值得) better. We still did not do anything, but someone else did. The homeless man, who I thought could not afford anything to eat, went into the store and bought dog food with all the money he had.Where did the story happen?

根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Two brightly colored butterflies have just flown by. They seems to be exactly alike, but actually one is a little larger than the other. 1The smaller one has a wingspread of less than three inches and also a black line on its back wings.
At first sight, it is hard to tell them apart. Would you guess from this that they are different-sized butterflies of the same species?2If you said yes to either question, you would be wrong, for these look-alikes belong to quite different families.
The larger insect is the monarch butterfly (黑脉金斑蝶). As a baby insect, the monarch feeds on milkweed, which seems to give the monarch a disagreeable taste and smell. 3Birds that eat butterflies soon recognize the monarch and quickly learn to leave it alone.
4Birds would find this insect tasty, but because it looks like the monarch, birds keep away from it. The viceroy’s similarity to the monarch gives it some protection from its enemies and helps it survive.
There are other pairs of look-alike butterflies, bees and moths. In each case, one either has a disagreeable taste or smell, or can give a painful sting (叮咬). The larger is called the model.5
| A．The smaller insect is the viceroy (副王峡蝶), which feeds on the leaves of trees. |
| B．The larger insect has a wingspread (翼长) of up to four inches. |
| C．The bright coloring of the monarch acts as a warning sign to its enemy. |
| D．Birds protect their babies from eating such dangerous enemies. |
E. The insect that imitates this model for protection is called the mimic（保护色）.
F. Or that they are different species of butterflies but close relatives belonging to the same family?
G. Do you like this kind of special species?
Frank Woolworth was born in Rodman, New York., in 1852. His family were very poor farmers, and there was never enough to eat. Frank decided he did not want to be farmer. He took a short business course, and went to work as a salesman in a large city.
Woolworth realized he had a natural skill for showing goods to attract people’s interest, but he soon learned something more important. One day his boss told him to sell some odds and ends (小商品) for as much as he could get. Frank put all these things on one table with a sign which said FIVE CENTS EACH. People fought and pushed to buy the things and the table was soon cleared.
Soon afterwards, Woolworth opened his own store, selling goods at five and ten cents. But he had another lesson to learn before he became successful. That is, if you want to make money by selling low-price goods, you have to buy them in large quantities directly form the factories. Once, for example, Woolworth went to Germany and placed an order for knives. The order was so large that the factory had to keep running 24 hours a day for a whole year. In this way, the price of the knives was cut down by half.
By 1919, Woolworth had over 1000 stores in the US and Canada, and opened his first store in London. He made many millions and his name became famous throughout the world.
