回答{TSE}题： Screen Test 1 Every year millions of women are screened with X-rays to pickup signs of breast cancer. If this happens early enough, the disease can oftenbe treated successfully. According to a survey published last year, 21countries have screening programmes. Nine of them, including Australia, Canada,the US and Spain, screen women under 50. 2 But the medical benefits of screening these younger women arecontroversial, partly because the radiation brings a small risk of inducingcancer.

第7题
Sociologists (社会学家) tell us that we are heading for a society leisure. The trend is unmistakable. One hundred years ago, they point out a worker put in twelve or thirteen hours a day, six days a week, and week followed week without an annual vacation. But over the years the picture has changed. Today the typical work week has five eight-hour days, and workers enjoy about three weeks of paid vacation every year, with the result that today me spend less than as much time on the job as people did before.
In spite of this, today's worker may not feel that he has a great deal of leisure time. This is because a lot of the non-work time is taken up with fulfilling family and social obligations. For example, he feels that he should spend some time with his children every day, and if a man does physical activity in his job, that too cuts into his free time.
Nevertheless, the final result is that we do have more leisure-more time free from the obligation of work or any other social requirement. Leisure is time not used to earn money or to do things around the house which save money. It is time spent only in seeking satisfaction, and we give up what we are doing when it no longer satisfies us. Leisure gives us the opportunity to recover from the physical and mental fatigue (疲倦) of work and it frees our creative talents from the pressure placed on us by the job.
Today's leisure is time programmed for doing what you want to. It does not have to be made up the next day. This is something new. It really frees a person from the workshop to enjoy, for a time, things in which he is interested. Man is about to go out to the playground.
People have ______ today.
A．more leisure
B．less work
C．less leisure
D．more work

Landmines
Worldwide there a，re estimated to be l 20 million landmines(地雷)spread through 62 countries．_________(46)The United Nations is currently involved in I 4’mine—clearing operations around the world but it estimates that，at current rate，it will take 1，000 years to remove all the world’s landmines．
Landmines are a favorable weapon because they cost SO little to produce——about 3 pounds per mine。_________ (47)
Landmines cause the death or injury of 70 people a day，of whom most are civilians．
_________ (48)In fact，about half the landmines active today lie in unmarked fields．In countries no longer in conflict．
And landmines do not only kill and maim(使残废)：they also hold back economic development．In Afghanistan，for example，where the former Soviet Army laid down art estimated ten million landmines，more than half of the land which could be cultivated for agriculture is useless because it is SO heavily mined．According to Eileen maybin of the charity Christian Aid，mines also condemn people to relying on overseas aid—aid which is often provided by governments which provided the landmines in the first place：
“_________ (49)Because there are landmines on agricultural land，people are actually dependent on food aid．This is one of the ironies of the situation——that governments are providing money for food aid when，if the mines were cleared，people would be able to feed themselves．”
Forty-nine countries have SO far signed, the United Nations Inhumane Weapons Convention which restricts the manufacture and export of landmines_________(50)But some signatories(签约国)of the UN Convention，such as the UK，continue to support the manufacture and export of these weapons。The British Government says that it won’t support a complete ban because it considers the landmine a legitimate(合法的)militia’s weapon if it is used responsibly．
A．A further 19 countries，including the USA，France，Germany and Japan，have banned all exports of landmines completely．
B．However, the cost of locating and removing them is high—between 300 pounds and 700 pounds per mine．
C．A recent UN gathering of world leaders in Vienna，Austria。failed to secure a complete ban on the manufacture and sale of landmines．
D．And every year, for every 100，000 mines removed，another two million are put down
E．Landmines are actually destroying the social fabric and economic independence of countries．
F．And many of the casualties occur in countries where war has long since ended．
