The way people hold to the belief that a fun-filled, painfree life equals happiness actually reduces their chances of ever getting real happiness．If fun and pleasure are equal to happiness then pain must be equal to unhappiness．But in fact, the opposite is true: more often than not things that lead to happiness is connected with some pain．
As a result, many people avoid the very attempts（嘗試）that are the source of true happiness They fear the pain brought by such things as marriage, raising children, professional achievement, religious commitment（承擔的義務(wù)），self-improvement．
Ask a bachelor（單身漢）why he refuses marriages even though he finds dating to be less and less satisfying, if he’s honest he will tell you afraid of making a commitment．For commitment is in fact painful．The single life is filled with fun, adventure, excitement．Marriage has such moments, but they are not its most unusual features．
Couples with baby children are lucky to get a whole night’s sleep or a three-day vacation．I don’t know any parent who would choose the word fun to describe raising children．But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild．
Understanding and accepting that true happiness has noting to do with fun is one of the most liberating realizations．It liberates（解放）time; now we can devote more hours to activities that can increase our happiness．It liberates money: buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless．And it liberates us from envy: we now understand that all those who are always having so much fun actually may not be happy at all．
48．Raising children, in the author’s opinion, is________．
A．a(chǎn) duty we should have to perform B．a(chǎn) thankless job
C．a(chǎn) source of pain that can’t be avoided D．a(chǎn) rewarding task
49．To understand what true happiness is one must________．
A．have as much fun as possible during ones lifetime
B．make every effort to free oneself from pain
C．put up with pain in all conditions
D．be able to tell happiness from fun
50．What is the writer trying to tell us?

Lichens (地衣) are difficult to see. They don’t move. They often mix into the living place. You might not even recognize one if you are looking right at it.
Lichens live on rocks, branches, houses, and even metal street signs. You can find these colorful organisms (微生物) almost everywhere — from deserts to rainforests, and from Antarctica to Africa. They’ve traveled in outer space, and some scientists think there might even be lichens on Mars.
What you probably don’t realize is that a lichen is more than a single thing. It includes two different types of living organisms: a fungus (菌類) and an alga (藻類). Neither of these organisms is a plant, so the lichen isn’t a plant either.
Through photosynthesis (光合作用), the alga gets the sun’s energy to make food for the fungus, which is the place for the alga to live in. However, the alga cannot leave the fungus.
Around the world, scientists have found tens of thousands of types of lichens. Many may not even have been discovered yet. As scientists continue to find new kinds of lichens, they are also working to understand how they are connected to one another. By putting together a lichen family tree, they hope to understand why so many different types of lichens have grown in so many places around the world.
Many researchers are trying to understand basic facts about the organisms and their connections. Researchers are also using lichens to examine the health of the environment.
What do we know about lichens according to the passage?
A. They will die if they leave Earth.
B. There are more lichens than plants on Earth.
C. They look similar to the environment around them.
D. They are too small to be easily seen by people.
What does the second paragraph mainly talk about?
A. The way lichens live.
B. The natural environment of lichens.
C. The way lichens work as organisms.
D. The family tree of lichens.
Which of the following statements is NOT the scientists’ purposes of studying lichens?
A. To understand basic facts about them.
B. To creat a lichen family tree.
C. To understand how lichens are related to each other.
D. To understand why lichens can live in different places.
We can know from the passage that __________.
A. lichens can be used to better understand the environment
B. lichens don’t have any differences in colors or sizes
C. lichens don’t use photosynthesis like a green plant
D. scientists have discovered every kind of lichen

Electronic waste, or e-waste, refers to electronic products that are no longer usable. This can include TVs, cell phones and computers and other office electronics, electronic toys and videos machines. Today, the average turnover（更換）rate for a computer in the United States is every two years, according to the environmental group, Greenpeace.
The group's Dai Yun says e-waste is a global problem. "The electronic industry is one of the fastest growing industries in the world. The high speed of growth in this industry means more and more electronic products are being wasted and thrown away. If no one decides to retrieve the old products and process them properly, the electronic waste will sweep over the earth like the huge wave behind me and pollute the Earth seriously."
Greenpeace works out that 20 to 50 million tons of e-waste are produced globally each year. The components（部件）in many electronic products contain harmful chemicals that pollute ground water and the environment.
At present , the U.S. has no federal law for the disposal (處理) of e-waste although a few states have e-waste recycling programs in place, but there is no law. The U.S. exports much of its e-waste to third world countries, such as India and China, where workers took apart computers for valuable parts, hoping to sell them for money. But harmful wastes expert, Dr. Bakul Rao, says that's a dangerous practice. "From now on, the recyclers are not very educated. All they know is they can retrieve copper or gold out of it. So, the easiest way to do that is leach (過濾) it out in an acid or burn it off to retrieve it. So, that's where they don't know how to deal with it, neither do they have any health systems in place. So, their exposure is more."
Which of the following is most likely not to be a form of e-waste?
A. A mobile phone B. A radio C. An e-bike D. A table
What does the underlined word "retrieve" (paragraph 2) probably mean?
A. look into B. take apart C. get back D. throw away
What of the following statements is true according to the passage？
A. The U.S. has strict national laws for dealing with e-waste.
B. Third world countries import e-waste to get valuable parts, which is a safe and easy way to
make money.
C. The way uneducated workers deal with old computers does great harm to the environment as well as to their own health.
D. More and more electronic waste is being wasted and thrown away mainly because of
people's bad habits.
What is the purpose of writing the passage?
A. To attract more people's attention to e-waste.
B. To call on people not to throw away e-waste anywhere.
C. To tell people what e-waste is and how to deal with it well.
D. To warn people to break away from the electronic industry.
The next paragraph probably concerns_______.
A. how to deal with e-waste properly
B. how to protect ourselves from harm by e-waste
C. How to slow down the development in the electronic industry
D. how to make full use of e-waste

They may be just passing your office, computer bag slung (懸掛) over one shoulder. Or they may be sitting in a car outside it, causally tapping away at a laptop. They look like innocent passers-by. In fact, they are stealing your corporate secrets.
Drive-by hacking is the trendy term given to the practice of breaking into wireless computer networks from outside the buildings that house them. A recent study in the UK, sponsored by RSA Data Security, found that two-thirds of organizations with wireless networks were risking their data in this way. Security experts patrolled (巡邏) several streets in the City of London seeking evidence of wireless networks in operation.
Of 124 that they identified, 83 were sending data without encrypting（加密）them. Such data could readily be picked up by a passer-by armed only with a portable computer, a wireless modem and a few pieces of software that can be freely downloaded from the Internet.
The data could include sensitive company documents containing valuable information. Or they could be e-mail identities and passwords that could be used by hackers to log into corporate networks as if they were legal users.
Most companies using wireless networking technology do not take even the simplest of measures to protect their data. Nearly all wireless network technology comes with some basic security features that need only to be activated (激活) in order to give a minimum level of security, for example, by encrypting the data being passed over the network.
Raymon Kruck, business development manager at Check Point Software, a security technology specialist, believes this could be partly a psychological problem. People see the solid walls of their building as safeguards and forget that wireless networks can extend up to 200 meters beyond physical walls.
Companies without any security at all on their wireless networks make it ridiculously easy for hackers to break in. Switching on the security that comes with the network technology should be automatic. Then there are other basic steps a company can take, says Mr. Kruck, such as changing the passwords on the network from the default (默認) setting.
Companies can also install firewalls, which form a barrier between the internal network and the public Internet. They should also check their computer records regularly to spot any abnormal activity, which might betray the presence of a hacker.
1.According to the study sponsored by RSA Data Security, two thirds of the subjects _______.
A. had most of their company data stolen
B. depended on wireless computer networks
C. were exposed to drive-by hacking
D. were unaware of the risk of wireless hacking
2.Which of the following is NOT considered in the study?
A. The number of computer hacking incidents.
B. The number of wireless computer networks identified.
C. The way in which data are sent and received.
D. The way in which data are hacked and stolen.
3.Most wireless network technology has_________.
A. data encryption program
B. password security programs
C. illegal-user detection
D. firewall
4.Raymond Kruck most probably agrees that wireless network security involves ________.
A. wireless signal administration
B. changes in user’s awareness
C. users’ psychological health
D. stronger physical walls
5.The passage is most likely to be seen in a __________
A. book review B. science fiction C. textbook D. computer magazine

A green house is a building made of glass which is used for keeping warm when the outside temperature is low. In a similar way there are several gases in the atmosphere (mixture of gases that surround the earth) which trap the heat produced by the sun and prevent it from escaping. These gases are known as “greenhouse gases”. and the way in which they trap heat in the atmosphere is called the “greenhouse effect”. This is not simply air pollution. Most of the main greenhouse gases exist naturally in small amounts in our atmosphere, and without them the earth would be 30 degrees colder and human life would not exist. In other words, the greenhouse effect is a natural course which is to some degree helpful to us.
The problem is that in the last century and a half, we have been putting too many of these gases into the earth’s atmosphere by burning large quantities of coal and oil and by cutting down forest. The rapid increase in greenhouse gases is making the world warmer. The world’s temperature has already gone up by half a degree this century, and the sea level has risen by 10 centimetres. If the amount of carbon dioxide in the atmosphere doubles, there will probably be a rise in the earth’s temperature of between I and 4℃;. This may seem a small increase, but it would be enough to cause major changes in geography and agriculture. Large areas of the world would be flooded, and some areas would become dry and unable to produce crops. It is important, too, to consider that there may be a delay of about 30 years in the greenhouse effect. This means that we are probably experiencing only now the effect of the gases put into the atmosphere before the 1960s. Since then, our use of these gases has greatly increased.
1. According to the passage, we can know “greenhouse effect” means_______.
A. the way in which gases are used for keeping plants warm
B. a natural course that is to a certain degree useful to us
C. the way “greenhouse gases” trap heat on the earth
D. the whole course in which greenhouse gases prevent heat
2. If there were no greenhouse effect,_______.
A. all plants would not grow on our planet B. soil would reduce the temperature by 30 degrees
C. man would breathe the cleaner air D. people couldn’t live in the earth
3. Which of the following is not true?
A. Burning too much coal and oil produces lots of greenhouse gases.
B. It has become warm on the earth now than in the past.
C. Gases put into the atmosphere now will affect the earth years later.
D. The temperature in a greenhouse is as high as that in the atmosphere.
4. Suppose the earth’s temperature rose by 3 degrees, _______.
A. great harm will be done to mankind B. the sea level would go up by 10 centimeters
C. all the land in the world would be flooded D. crops would be unable to grow on the earth
5. This passage mainly deals with ________.
A. the concept (概念) and the harm of the greenhouse B. the relation between greenhouse gases and man
C. the concept and change of greenhouse effect D. the effect of the rise of the earth’s temperature
