　　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 Seymour's 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“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 we've 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 Seymour's innovative solution is to mask the virus from the body's immune system, …… “mask”的意思是“掩盖、隐蔽、伪装”， 在这里和 “disguise”同义。）
