2、有时还需参考试题中的另一篇*。由于干扰因素很多，猜对的可能性几乎为零。IELTS考试阅读部分与其他阅读考试的另一重大区别是，IELTS考试不仅不含语法和词汇题，反而可能会列出若干关键词和定义，以帮助考生更好地理解。阅读(学术类)介绍：阅读考试形式IELTS考试阅读(学术类)部分共有三篇*，考生需要回答40道题目。每一篇*所需要回答的问题数量并不相同。每一道问题相对应一个分数。*内容和题目均出现于问卷中。作答方式考生需将答案填写在答卷中。考试时间IELTS考试阅读(学术类)部分总共用时60分钟。考生应在考试时间内将答案转抄至答卷上，转抄答案不会获得额外的时间。计分方式每正确回答一道问题，考生将获

6、scientists are preparing to launch trials of a radical new way to fight cancer, which kills tumours by infecting them with viruses like the common cold.2. If successful, virus therapy could eventually form a third pillar alongside radiotherapy and chemotherapy in the standard arsenal against cancer,

7、 while avoiding some of the debilitating side-effects.3. Leonard Seymour, a professor of gene therapy at Oxford University, who has been working on the virus therapy with colleagues in London and the US, will lead the trials later this year. Cancer Research UK said yesterday that it was excited by t

8、he potential of Prof Seymours pioneering techniques.4. One of the countrys leading geneticists, Prof Seymour has been working with viruses that kill cancer cells directly, while avoiding harm to healthy tissue. In principle, youve got something which could be many times more effective than regular c

9、hemotherapy, he said.5. Cancer-killing viruses exploit the fact that cancer cells suppress the bodys local immune system. If a cancer doesnt do that, the immune system wipes it out. If you can get a virus into a tumour, viruses find them a very good place to be because theres no immune system to sto

10、p them replicating. You can regard it as the cancers Achilles heel.6. Only a small amount of the virus needs to get to the cancer. They replicate, you get a million copies in each cell and the cell bursts and they infect the tumour cells adjacent and repeat the process, said Prof Seymour.7. Prelimin

11、ary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. Its an interesting possibility that they may have an advantage in killing drug-resistant tumours, which could be quite different to anything weve had before.8. Researchers have known for some time th

American scientists have previously injected viruses directly into tumours but this technique will not work if the cancer is inaccessible or has spread throughout the body.9. Prof Seymou

13、rs innovative solution is to mask the virus from the bodys immune system, effectively allowing the viruses to do what chemotherapy drugs do - spread through the blood and reach tumours wherever they are. The big hurdle has always been to find a way to deliver viruses to tumours via the bloodstream w

14、ithout the bodys immune system destroying them on the way.10. What weve done is make chemical modifications to the virus to put a polymer coat around it - its a stealth virus when you inject it, he said.11. After the stealth virus infects the tumour, it replicates, but the copies do not have the che

15、mical modifications. If they escape from the tumour, the copies will be quickly recognised and mopped up by the bodys immune system.12. The therapy would be especially useful for secondary cancers, called metastases, which sometimes spread around the body after the first tumour appears. Theres an aw

Two viruses are likely to be examined in the first clinical trials: adenovirus, which normally causes a cold-like illness, and vaccinia, which causes cowpox and is also use

17、d in the vaccine against smallpox. 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.14. The first trials will use uncoated adenovirus and vaccinia and will be delivered locally to liver tumours, in o

Several more years of trials will be needed, eventually also on the polymer-coated viruses, before the therapy can be considered for use in the NHS.
