“I sometimes get up at three or four in the morning and I surf the net.”
“I often check my e-mail forty times a day. ”
“I often spend more than three hours during one time on the net.”
“I spend more time in chat rooms than with my ‘real-life’ friends.”
Do you know any people like these? They are part of a new addiction(上瘾)called Internet addiction. Internet addicts spend at least thirty to forty hours online every week. The use of the Internet can be an addiction like drug(毒品)use. People lose control(控制)of the time they spend on the Internet.
For example, one college student was missing for several days. His friends were worried, and they called the police. The police found the student in the computer lab: he was surfing the net for several days straight.
Studies show that about 6% to 10% of Internet users become addicted. And people worry about the teens because the Internet is changing the playing field for some of them. They spend more time in cyberspace than in the real world of friends and family.
Is “surfing the net” a hobby or an addiction for you? You may have a problem if you have these symptoms(症状): ①You do not go to important family activities or you do not do school work because you like to spend hours on the Internet. ②You can’t wait for your next online time. ③You go out with your friends less and less. ④You plan to spend a short time online, but then you spend several hours.How does the writer describe the addicts’ use of Internet?

A.The teens are wasting too much money. |
B.They used to work on the Internet. |
C.The playing field of the teens will disappear. |
D.More and more of the teens will become addicted to the Internet. |
The example in the passage shows that .
A.some of the Internet users have already been seriously addicted |
B.Internet addicts usually stay in the computer lab without sleep |
C.Internet problems are more serious among college students |
D.the police often help to find those Internet addicts |

C.Don’t be addicted to the Internet. | D.Stay with your parents as often as possible. |
When a starving man gets a meal, he begins to think about an overcoat; when an executive gets a new sports car, visions of country clubs and pleasure beats dance into view.
The many wants of mankind might be regarded as making up several levels. .
The first and most basic level of wants involves food. Once this want is satisfied, a second level of wants appears: clothing and some sort of shelter. By the end of World War II these wants were satisfied for a great majority of Americans. It included such items as automobiles and new houses.
By 1957 or 1958 this third level of wants was fairly well satisfied. Then, in the late 1950s a fourth level of wants appeared: the “life-enriching” level. While the other levels involve physical satisfaction-the feeding, comfort, safety, and transportation of the human body-this level stresses mental needs for recognition, achievement and happiness. It includes a variety of goods and services, many of which could be called “luxury” items. Among them are vacation trips, the best medical care, and entertainment.
On this level, a greater percentage of consumer spending goes to services, while on the first three levels more is spent on goods. Will consumers raise their sights to a fifth level of wants as their income increases, or will they continue to demand luxuries and personal services on the fourth level?
A fifth level probably would involve wants that can be achieved best by community action. Consumers may be spending more on taxes to pay for government action against disease, ignorance, crime and prejudice. In this way, we can enjoy more fully the good things on the first four levels.
A.Then a third level appeared. |
B.Human wants seem endless. |
C.When there is money enough to satisfy one level of wants, another level appears. |
D.There are several levels of wants in one’s life. |
E. At this stage, we now may seek to ensure the health, safety, and leisure.
F. Also included here are fancy foods and the latest styles in clothing.
G. Different people have different wants on each level.
What will power your house in the future?Nuclear,wind,or solar power?According to scientists at the Massachusetts Institute of Technology (MIT) in the US,it might be leaves — but artificial (人造的) ones.
Natural leaves are able to change sunlight and water into energy. It is known as photosynthesis (光合作用).Now researchers have found a way to imitate this seemingly simple process.
The artificial leaf developed by Daniel Nocera and his colleagues at MIT can be seen as a special silicon chip with catalysts (催化剂).Similar to natural leaves,it can split water into hydrogen and oxygen when put into a bucket of water. The hydrogen and oxygen gases are then stored in a fuel cell,which uses those two materials to produce electricity,located either on top of a house or beside the house.
Though the leaf is only about the shape of a poker card,scientists claimed that it is promising to be an inexpensive source of electricity in developing countries. “One can imagine villages in India and Africa not long from now purchasing an affordable basic power system based on this technology,” said Nocera at a conference of the American Chemical Society.
The artificial leaf is not a new idea. The first artificial leaf was invented in 1997 but was too expensive and unstable for practical use. The new leaf,by contrast,is made of cheap materials,easy to use and highly stable. In laboratory studies,Nocera showed that an artificial leaf prototype (原型) could operate continuously for at least 45 hours without a drop in activity.
The wonderful improvements come from Nocera's recent discovery of several powerful,new and inexpensive catalysts. These catalysts make the energy transformation inside the leaf more efficient with water and sunlight. Right now,the new leaf is about 10 times more efficient at carrying out photosynthesis than a natural one. Besides,the device can run in whatever water is available;that is,it doesn't need pure water. This is important for some countries that don't have access to pure water.
With the goal to “make each home its own power station” and “give energy to the poor”,scientists believe that the new technology could be widely used in developing countries,especially in India and rural China.Which of the following orders correctly shows how the artificial leaf is used to produce electricity?
a.artificial leaves split water into hydrogen and oxygen
b.the hydrogen and oxygen gases are stored in a fuel cell
c.the artificial leaves are put in water
d.the fuel cell uses hydrogen and oxygen to produce electricity
A.c,a,b,d | B.c,b,a,d |
C.b,c,a,d | D.c,a,d,b |
The purpose of the scientists at MIT in developing the new artificial leaf is to________.
A.build up more power stations in the world |
B.provide cheaper energy for developing countries |
C.offer people in developing countries access to pure water |
D.gain a deeper understanding of the photosynthesis process |
The main idea of this passage is ________.
A.an introduction to the history of artificial leaves |
B.a mixture of water power and solar energy |
C.giving energy to the poor |
D.an invention copying photosynthesis |
Pilling a cat can be a 'terrible” experience. Cats don’t want something pushed down their throats, and they’ll fight with all their strength to prevent it. In fact, it’s amazing how powerful their small bodies can be.
The easiest way of pilling a cat is to press the pill into powder. Then mix the powder with a small amount of wet food. If your cat usually eats dry food, she will probably view the wet food as a treat and eat it up.
If your cat won’t eat the wet food that contains the pill or if she is too ill to eat, you can get a “pill gun”. There are some basic instructions. Getting your cat’s mouth to open is going to be the most difficult part. First, be sure the pill is in a handy place. Then you can put your cat on a bookshelf with her bottom in a corner or you can put her on your lap firmly tied. Have your cat facing to the right if you’re right-handed. With your left hand, hold your cat at the cheekbones, putting your palm (手掌) at the top of her head. Keeping your finger off the trigger (扳机), with your right hand, insert the pill gun until the pill is positioned over the tongue and open throat. Be sure to give your cat a treat directly after giving the pill.
If you don’t feel comfortable using a pill gun, you can try giving the pill by hand. Push your cat’s head backwards just far enough so that her nose is pointing towards the ceiling. At this point, most cats will slightly open their mouths. With the little finger or ring finger of the hand holding the pill, open the bottom jaw a little more. You may need to hold her top jaw with your other hand while doing this. Aim straight and lightly throw the pill or drop it. Most cats will then swallow the pill.Pilling a cat can be a terrible experience because cats ______.
A.are amazingly powerful and dangerous |
B.may fight with all their strength against pills |
C.refuse something pressed down their throats |
D.are difficult to treat once they’ve got ill |
Which of the following statements is true according to the second paragraph?
A.Wet food with medicine is usually a treat to cats. |
B.Cats used to dry food must reject wet food. |
C.The easiest pilling is to press the pill into powder. |
D.Cats are most likely interested in something new. |
Using a “pill gun”, you had better hold your cat ______ if you’re left-handed.
A.facing to the right | B.with your right hand | C.at the head | D.on your lap firmly |
A cat probably opens its mouth naturally when ______.
A.its nose is straight upwards | B.it is touched by fingers |
C.its head is turning around | D.it is served with its favorite pills |

Read a lot, I mean a lot! You have to increase your ability for reading. Many students are in the habit of reading only when their exams are approaching while some others read only what they are taught or things that must be read because it is in their curriculum. But listen to me now, I am telling you from my own experience that it is a very bad habit and it is not enough to improve your intelligence.
You have to learn and get ready to become versatile in your reading. The fact that you are studying medicine in school does not mean that you should not know one or two things on politics.
Many people have complained to me that they find it hard to read stuffs like novels but I just shake my head in pity for them because it is obvious they have failed to realize the truth in that wise saying by Margaret Fuller that “today a READER, tomorrow a LEADER!”
When you read, you get to “see” so many places and it will be as if you have visited those places in real life. This is because reading will improve your imagination and creativity and understanding. You also get experience from learning about how people dealt with their various problems thereby saving you from going through the pains and difficulties they must have gone through!
Reading will also help you in improving your vocabulary because you will certainly start coming across so many new words which you will try as much as possible to get accustomed to with the help of the dictionary! The good thing about increasing your vocabulary is that it will also improve your thinking ability. After all, we think in words and the more words you know, the easier it will become for you to express yourself or your thoughts.
And when you read, make sure you read so wide because the more you read, the more you know and the more you know the more intelligent you can become.According to the author, what should students do in terms of reading?
A.They needn’t read unless the exams come. |
B.They should read books about intelligence. |
C.They must read about politics when their major is medicine. |
D.They should read as wide as possible. |
The underlined word “versatile” in Paragraph 2 is closest in meaning to _____.
A.interested | B.many-sided | C.content | D.confident |
What is the best title for the passage?
A.Increase your ability for reading |
B.Read wide and improve your vocabulary |

D.Reading makes you a leader tomorrow |
What is the benefit of knowing more words?
A.You will get used to referring to the dictionary when meeting with new words. |
B.You will have less difficulty expressing your opinions. |
C.Vocabulary will improve your creativity. |
D.You can pass your exams with ease. |
