Answers Keys:

　　1.答案：FALSE (見第2段：If successful, virus therapy could eventually form a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer, while avoiding some of the debilitating side-effects. Virus therapy 只能避免一些副作用，而不是根除。)

　　2.答案：TRUE (見第3段，特別是最后一句： Cancer Research UK said yesterday that it was excited by the potential of Prof Seymour’s pioneering techniques. )

　　3. 答案：NOT GIVEN (文中沒有提到virus可以抑制腫瘤細胞再生長)

　　4. 答案：TRUE (見第5段第3、4句： 這里“cancer's Achilles' heel”指 “If you can get a virus into a tumour, viruses find them a very good place to be because there’s no immune system to stop them replicating.” Achilles' heel的意思是“唯一致命弱點”)

　　5. 答案：FALSE (見第6段第第1句：Only a small amount of the virus needs to get to the cancer.)

　　6. 答案：TRUE (見第7段：Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drug. ..., which could be quite different to anything we’ve had before." )

　　7. 答案：B (見第8段第1、2句：Researchers have known for some time that viruses can kill tumour cells and some aspects of the work have already been published in scientific journals. Journal意思是“日報、期刊、雜志”)

　　8. 答案：D (見第9段第1句：Prof Seymour's innovative solution is to mask the virus from the body’s immune system, ... “mask”的意思是“掩蓋、隱蔽、偽裝”， 在這里和 “disguise”同義。)

　　9. 答案：B (見第11段第2句： If they escape from the tumour, the copies will be quickly recognised and mopped up by the body’s immune system.. “mop up”這里與 “wipe out” 同義，意思是“消滅、殲滅”。)

　　10.答案：disable (見第13段最后1句：For safety reasons, both will be disabled to make them less pathogenic in the trial, but Prof Seymour said he eventually hopes to use natural viruses. )

　　11. 答案：natural ones (見第13段最后1句：For safety reasons, both will be disabled to make them less pathogenic in the trial, but Prof Seymour said he eventually hopes to use natural viruses. )

　　12. 答案：dosage (見第14段第1句：The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours, in order to establish whether the treatment is safe in humans and what dose of virus will be needed.)

　　13. 答案：directed (見第14段最后1句：Though the approach will be examined at first for cancers that do not respond to conventional treatments, ...)
