2021年雅思阅读模拟题及答案（卷二）

The Guardian1. British 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, 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 the potential of Prof Seymour's pioneering techniques.

4. One of the country's leading geneticists, Prof Seymour has been working with viruses that kill cancer cells directly, while avoiding harm to healthy tissue. \"In principle, you've got something which could be many times more effective than regular chemotherapy,\" he said.

5. Cancer-killing viruses exploit the fact that cancer cells suppress the body's local immune system. \"If a cancer doesn't 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 there's no immune system to stop them replicating. You can regard it as the cancer's 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. Preliminary research on mice shows that the viruses work well on tumours resistant to standard cancer drugs. \"It's an interesting possibility that they may have an advantage in killing drug-resistant tumours, which could be quite different to anything we've had before.\"

8. 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. 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 Seymour's innovative solution is to mask the virus from the body's 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 without the body's immune system destroying them on the way.

10. \"What we've done is make chemical modifications to the virus to put a polymer coat around it - it's 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 chemical modifications. If they escape from the tumour, the copies will be quickly recognised and mopped up by the body's 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. \"There's an awful statistic of patients in the west ... with malignant cancers; 75% of them go on to die from metastases,\" said Prof Seymour.

13. 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 used 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 order to establish whether the treatment is safe in humans and what dose of virus will be needed. 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. Though the approach will be examined at first for cancers that do not respond to conventional treatments, Prof Seymour hopes that one day it might be applied to all cancers.

From Economist.com

1 NEELIE KROES, the European Union’s competition commissioner, did not mince her words when reporting on Europe’s energy markets on Wednesday January 10th. Europe’s energy firms have failed to invest in networks and so customers are suffering. Those “vertically integrated” energy companies such as Electricité de France (EDF) or Germany’s E.ON, widely dubbed as “national champions”, are effectively behaving like local monopolies. Shy of competition, eager for artificially high prices, they are helping to block the efficient generation, transmission and distribution of energy on the continent.

2 Energy prices vary wildly across Europe. Ms Kroes wants to see cheaper energy, and intends to push suppliers to divest their distribution network and to get them to invest more in transportation systems so that more energy—in the form of gas, or electricity, for example—can flow easily over borders. It is remarkably hard, for example, for gas-poor Germany to import from the neighbouring, gas-rich Netherlands. Companies that dominate national markets have, so far, had little interest in improving the interconnections which would mean lower prices for consumers across the continent.

3 Ms Kroes, of course, will struggle to get her way. The European Commission, which on the same day presented its recommendation for improving EU energy policy, also wants to see the unbundling of ownership, the legal separation of

energy suppliers and transporters, something that the integrated energy companies and interested governments, notably in France and Germany, are bound to oppose ferociously.

4 Complicating the matter is an argument over the security of energy supply in Europe. Much has been made of the risk for western Europe of depending too heavily on Russian exports of gas. Russia under Vladimir Putin is prone to using energy exports as a blunt tool of foreign policy, especially when trying to bully countries in its hinterland. Last year Russia interrupted gas deliveries to Ukraine, affecting supplies in central and western Europe too. This week it blocked oil exports passing via Belarus to Europe, though that spat was soon resolved.

5 The risk is that concerns about security of supply may be used spuriously by those in Europe who oppose the sort of liberalisation encouraged by Ms Kroes. The likes of E.ON and EDF may claim that only protected national champions are able to secure supply, by striking long-term deals with powerful foreign suppliers. The Commission disagrees. Such deals are too often politically motivated and far from transparent. Protection has been tried for long enough and evidently has not worked for the internal market, nor have these companies secured the best deals for consumers from the Russians.

6 In contrast, the Commission's new policy proposes, ideally, a break-up of these companies into suppliers and distributors. (As a second best solution, especially for France and Germany, it recommends the management of the networks by a third party.) Properly independent managers of Europe's energy

networks would have a strong incentive to build interconnecting pipelines and power lines across borders. For the gas market another means of ensuring competition and security would be finding a more diverse range of suppliers, for example by building more terminals for the import of liquified natural gas. It would also be likely to mean lower prices, if the example of liberalised Britain over the past ten years is anything to go by.

7 Whether any of this is likely to happen soon, however, is another matter. The Commission is also calling for European governments to agree on a common effort to reduce carbon emissions by at least 20% by 2020 (compared with 1990 levels). If America is willing to play ball, the Commission proposes to reduce emissions by as much as 30%. Achieving either target would mean promoting cleaner cars, a more effective emissions-trading system for Europe, wider use of public transport and a sharp increase in the use of renewable sources of energy, like wind and solar power. All that is laudable enough, but will also require political horse-trading as governments—Europe’s leaders are due to meet in March to discuss the various energy proposals—try to avoid commitments that may hurt domestic energy companies or make European firms less competitive than rivals in America, Asia and elsewhere.
