【题目】 Fearmongering (散布恐慌) against China more dangerous to global economy than coronavirus.

After weeks of attempting to make chaos and spread fear about the outbreak of the novel coronavirus epidemic in China, some overseas media outlets and individuals have shifted focus to another battlefield — the Chinese economy. They paint a rather dark picture not just for the Chinese economy but for the global economy.

1People cannot help but panic about the global economy, which is already facing serious challenges like trade wars. It is easy to point fingers at China for “causing” such a mess for the world.

Anyway, these media outlets are right about a couple of things. 2 After all, consumers across the country are trapped in their homes and businesses and factories have been shut for a good part of this year. Second, we have to be fully aware of these challenges and risks in order to address the problem. The first step to solve a problem is to recognize there is one.

3 If not, why would they invest hundreds of billions of dollars into the economy if they weren’t aware of the problem? Why would they roll out a great number of measures to support businesses?4

Regardless of how severe the impact will be, the epidemic does not change the fundamentals of the Chinese economy.5 There will be no reason that the vast Chinese consumer market will abruptly disappear or the world will suddenly no longer need products from the massive Chinese manufacturing sector, not to mention the country’s huge investment projects. So it can be safe to say that fearmongering against China is more dangerous to global economy than coronavirus.

A.With the effective measures taken by the whole country, the epidemic will be definitely under control.

B.Certainly, that paints a completely different picture we have seen from abroad.

C.First, the epidemic will make the Chinese economy suffer a little.

D.Still, there are many indicators to look for in assessing the potential damage on the Chinese and global economies.

E.Their articles are filled with scary headlines and exaggerated (夸大的) facts.

F.Why would they take extraordinary risks in encouraging factories to restart production?

G.Actually, Chinese officials have been very clear about the potential impact of the epidemic on the economy.

【题目】Two thirds of cancers are unavoidable even if you live a healthy life, a study has shown.

Scientists in the US found cancers are caused by random mistakes in the genetic code that occur when cells divide. The findings challenge the widespread view that cancer mutations are generally inherited or caused by environmental factors.

Lead scientist Dr. Cristian Tomasetti, from Johns Hopkins Kimmel Cancer Center in the US, said, “It is well-known that we must avoid environmental factors such as smoking to decrease our risk of getting cancer. But it is not as well-known that each time a normal cell divides and copies its DNA to produce two new cells, it makes various mistakes.”

The research, published in the journal Science, indicates that almost two-thirds of cancer-causing mutations are due to DNA copying errors. Overall, 66% of cancer mutations resulted from copying errors, 29% from lifestyle or environmental factors, and just 5% from inherited faulty genes. The discovery helps explains why cancer often strikes people who follow all the rules of healthy living and have no family history of the disease. Cancers caused by copying errors could occur no matter how perfect the environment is.

Professor Mel Greaves, director of the Centre for Evolution and Cancer at the Institute of Cancer Research in London, said, “Even if, as this study suggests, most individual cancer mutations are due to random chance, the researchers admit that the cancers they cause may still be preventable.”

“We have good evidence to show that cancer is caused by a complex mix of environmental exposures, inherited risk, and random chance. And while the genes we inherit from our parents are unchanged and many chance events are unavoidable, fortunately for us, exposures are major contributors to our risk of cancer and offer a route to risk reduction or prevention.”

1What mainly causes cancers in the original belief?

A. Cancers are caused by random mistakes in the genetic code.

B. Cancers are usually caused by inheritance or environmental factors.

C. Cancers are usually caused by poisonous food.

D. It is undiscovered how cancers occur.

2Which of the following is consistent with the passage?

A. Most people know that when a normal cell divides, it makes many errors.

B. As long as the environment is beneficial, people needn’t be concerned about cancers.

C. People with a healthy lifestyle won’t get cancers.

D. DNA copying errors are chiefly to blame for cancer mutations.

3From Greaves’s words, which of the following is acceptable?

A. The cancers caused by copying errors may be avoidable.

B. We need change the genes that we inherit form our parents.

C. Cancers are caused by some single factor.

D. We have to accept the fact that cancers will be incurable.

4Which section may the text belong to in a newspaper?

A. Environment. B. Humanities. C. Discovery D. Technology.
