[单项选择] The biggest problem facing Chile as it promotes itself as a tourist destination to be reckoned with, is that it is at the end of the earth. It is too far south to be a convenient stop on the way to anywhere else and is much farther than a relatively cheap half-day’’s flight away from the big tourist markets, unlike Mexico, for example.
Chile, therefore, is having to fight hard to attract tourists, to convince travelers that it is worth coming halfway round the world to visit. But it is succeeding, not only in existing markets like the USA and Western Europe but in new territories, in particular the Far East. Markets closer to home, however, are not being forgotten. More than 50% of visitors to Chile still come from its nearest neighbor, Argentina, where the cost of living is much higher.
Like all South American countries, Chile sees tourism as a valuable earner of foreign currency, although it has been far more serious than most in promoting its image abroad. Relatively stable

[填空题]Ann Scott:
People who leave litter behind them are anti-social. They spoil the beauty of the countryside and create all sorts of inconveniences, and even danger for other people. Broken bottles and rusty cans cause serious injuries especially to children. Old magazines and empty packages help to start fire when fools throw away matches and cigarette butts. Why can’t people be more careful Dropping litter is a disgusting habit. If you don’t do it in your oval house to keep it clean and tidy, why should you do it in public places to make them dirty and look ugly I never drop litter and I don’t allow my children to. Unfortunately, most parents these days don’t bring their children up properly. It’s a mother’s duty to teach her children how to behavior and to set a good examples herself.

[不定项选择题]共用题干
1.Is there something seriously wrong with marriage today?During the past 50 years,the rate of divorce in the United States has exploded:almost 50%of marriages end in divorce now,and the evidence suggests it is going to get worse.If this trend continues,it will lead to the breakup of the family,according to a spokesperson for the National Family Association.Some futurists predict that in 100 years, the average American will marry at least four times, and extramarital（婚外的）affairs will be even more common than they are now.
2.But what are the reasons for this,and is the picture really so gloomy?The answer to the first question is really quite simple:marriage is no longer the necessity it once was.The institution of marriage has been based for years partly on economic need.Women used to be economically dependent on their husbands.But with the rising number of women in well-paying jobs,this is no ionger the case.So they don't feel that they need to stay in a failing marriage.
3.In answer to the second question,the outlook may not be as pessimistic as it seems.While the rate of divorce has risen,the rate of couples marrying has never actually fallen very much,so marriage is still quite popular. In addition to this,many couples now simply live together and don't bother to marry.These couples are effectively married,but they do not appear in either the marriage or divorce statistics.In fact,more than 50% of first marriages survive.
4.So is marriage really an outdated institution?The fact that most people still get married mndicates that it isn't. And it is also true that married couples have a healthier life than single people: they suffer less from stress and its consequences such as heart problems,and married men generally consider themselves more contented than their single counterparts.Perhaps the key is to find out what makes a successful marriage and apply it to all of our relationships!
An important reason for the high divorce rate is that_________.
A.women are not economically dependant any more
B.more than 50%
C.more contented
D.finds out the key to a happy marriage and apply it to our relationship
E.almost 50%
F.women no longer need a husband any longer

[单项选择]
Humans are forever forgetting that they can’t control nature. Exactly 20 years ago, a Time magazine cover story announced that "scientists are on the verge of being able to predict the tome, place and even the size of earthquakes." The people of quake-ravaged Kobe learned last week how wrong that assertion was.
None of the methods conceived two decades ago has yet to discover a uniform warning signal that preceded all quakes, let alone any sign that would tell whether the coning temblor is mild or a killer. Earthquake formation can be triggered by many factors, says Hiroo Kanamori, a seismologist at the California Institute of Technology, so, finding one all-purpose warning sign is impossible. One reason: Quakes start deep in the earth, so scientists can’t study them directly. If a quake precursor were found, it would still be impossible to warn humans in advance of all dangerous quakes, places like Japan and California are riddled with hundreds, if
A. It is hard to build structures strong enough to withstand serious temblors.
B. Not all structures can be made to withstand the tremor of the earthquakes.
C. The degree of damage caused by earthquakes to different buildings can hardly be predicated accurately.
D. No structures would be strong enough to endure violent earthquakes.
