題目列表(包括答案和解析)

A. “Better road design and training hold the key to cycle safety”, the new Transport Secretary said today as he pledged to restore Britain’s safety record. Patrick McLoughlin told Conservative Party Conference that while cycling was enjoying a post-Olympics boom, the number of casualties among cyclists was also rising. “But the number of accidents has gone up too. That means it needs better design and better education too.” Mr McLoughlin said in his first speech as Transport Secretary. 
B.  Cycling in the UK will become safer through “sheer weight of numbers,” the founder of one of the world’s leading cycle brands has said as he backed The Times’s Cyclesafe campaign. Simon Mottram, founder and chief executive of Rapha, has added his support to 40 cross-party MPs who have signed a letter urging David Cameron to use his speech at the Conservative Party Conference to promote measures to make the streets safer for cyclists.
C.  Commuters who cycle to work face an increased danger as the casualty toll during peak hours rose by 10 percent last year. The rate at which cyclists were killed or seriously injured rose sharply last year, official figures showed yesterday.
D.  In future decades, Londoners will look back on the way cyclists jostled with buses and lorries on major roads as an absurd anachronism. Some risks are unavoidable. But other risks survive only because we are too slow to embrace bold solutions. That is the message from designers who are proposing an ambitious plan to create cycle lanes suspended above London’s busiest streets. London is one of the most dangerous places in the world for cycling. “SkyCycle” would remedy that problem by attaching dedicated cycle paths to existing railway viaducts.
E.  Money should be apportioned from the funding for major transport projects, such as the new Forth Crossing, to create a pot of cash for cycling, campaigners have told MSPs. Cycle groups have given warning that not enough money is being put into routes and promotion. They want the Scottish government to take a percentage of the funding allocated to key national projects and create an “active transport” fund to be distributed gradually.
F.  We’d like you to tell us why you love cycling by sending a photo of yourself, a family member or friend with their bike and a note about why it is so brilliant. To take part, instagram your photo with the hashtag #ilovemybike or email it to us at ilovemybike@thetimes.co.uk. We’ll post the best pictures here ilovemybike.tumblr.com.
請閱讀以下信息,并為他們匹配合適的新聞內容。
【小題1】“Cycle lanes in the sky” answer to traffic danger
【小題2】More cyclists are seriously injured on Britain’s roads
【小題3】Share a picture of you and your bike and help us promote the fun and freedom of cycling
【小題4】“Weight of numbers” will bring safe cycling
【小題5】Transport Secretary calls for better road design and training to help cyclists

A.The great impact and progress in genetic engineering
B.Worries about privacy protection
C.Worries about medical use of genetic engineering
D.Genetic knowledge helps to predict diseases
E.Genetic knowledge may not be properly used
AB.The application of genetic engineering in the medical fields
 
【小題1】__________
Current research into the human gene system is helping us understand why people have predispositions(易患某病傾向)to certain diseases.Knowing our genetic makeup can help us to judge whether or not we may be stricken by particular illness, such as cancer.Even before birth, we are able to do genetic screenings to determine what a child's genetic disorder will be.Scientists have already isolated and identified the genes responsible for the more than 4,000 genetic diseases that affect human beings.
【小題2】__________
The implications of this knowledge are astonishing. In addition to predicting genetic predisposition towards diseases, gene therapies may provide new treatments or cures for serious diseases.Millions of people already use genetically engineered drugs to treat heart disease, cancer, AIDS, and strokes (中風). But with the research that is now being conducted, we may find cures to many more diseases.In the near future, genetic experimentation will also allow parents to select the traits of their children. Genetic traits that determine height, weight, eye and hair color will be able to be controlled, and many parents are excited about this potential.
【小題3】__________
Many people, however, are unwilling to accept the possibilities genetic research allowsFor example, one reason some women do not use the largest genetic testing for breast cancer is because they are afraid they will be discriminated against.Another problem is that many people do not want to discover their weakness.What if they learn that they have a disease for which there are no medical cures? How will such knowledge affect their lives? Do people really want to know what they will die of?
【小題4】__________
Many people believe that history has not always shown human decision-making to be bright when it comes to ethical(道德的)choices. Jeremy Rifkin is probably the most well known opponent of genetic engineering. He believes that humans are not responsible enough to experiment with genes and should not “play God” He asks, “Just because it can be done, does that mean it should be done?” He points out that our society will eventually look and act the same if parents select the traits of their children, and he questions the desirability of such a society.
【小題5】.__________
One of the fears expressed about genetic experimentation involves privacy. Already blood sample taken from patients in hospitals have been used for genetic research without the patients’ permission. Most people would agree that one’s health and genetic makeup are private concerns. But if insurance companies gain access to this information, it could have a large impact on insurance coverage or costs; if employers gain access to the information, it could have a large impact on hiring or promotion decisions. The possibilities for discrimination are obvious.
