Answers Keys:
1．答案：FALSE （见第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 （见第3段，特别是最后一句： Cancer Research UK said yesterday that it was excited by the potential of Prof Seymours pioneering techniques. ）
3. 答案：NOT GIVEN （文中没有提到virus可以抑制肿瘤细胞再生长）
4. 答案：TRUE （见第5段第3、4句： 这里cancers Achilles heel指 If you can get a virus into a tumour, viruses find them a very good place to be because theres no immune system to stop them replicating. Achilles heel的意思是唯一致命弱点）
5. 答案：FALSE （见第6段第第1句：Only a small amount of the virus needs to get to the cancer.）
6. 答案：TRUE （见第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 weve had before. ）
7. 答案：B （见第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意思是日报、期刊、杂志）
8. 答案：D （见第9段第1句：Prof Seymours innovative solution is to mask the virus from the bodys immune system, mask的意思是掩盖、隐蔽、伪装， 在这里和 disguise同义。）
9. 答案：B （见第11段第2句： If they escape from the tumour, the copies will be quickly recognised and mopped up by the bodys immune system mop up这里与 wipe out 同义，意思是消灭、歼灭。）
10．答案：disable （见第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 （见第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 （见第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 （见第14段最后1句：Though the approach will be examined at first for cancers that do not respond to conventional treatments, ）
