19.---He's got our tickets.
---That's good I      afraid that he       them.(  )
A.am; has forgottenB.was; had forgotten
C.was; forgetD.am; will forget

分析 ---他有我们的票.
---太好了,我还担心他把它们给忘了.

解答 答案:B
根据句意可知,此处"担心他忘了"是发生在"现在知道他没忘"之前的动作,故第一空用一般过去式was;由于主句使用了一般过去式,从句应使用相应的过去式形式,故排除C;故选B.

点评 做本题时,首先应根据句意判断出动作发生的时间,从而确定出它的时态;其次应了解一般过去时的意义及用法,以及在含有宾语从句的主从复合句中,如果主句是一般过去时,从句要用过去的相应时态.

A healthy amount of sunshine may be the secret to staying young. British scientists have discovered.

Vitamin D is produced naturally by the skin in response to (对…的反应) sunlight and may help to slow the ageing process and protect against heart disease, according to the study.

Researchers from King's College London studied 2,160 women aged between 18 and 79, looking at their telomeres-a biological marker of ageing found in DNA. As people get older, their telomeres get shorter and they become more susceptible (易受伤害的) to certain illnesses.

But the study found women with high levels of vitamin D had comparatively longer telomeres-a sign of being biologically younger and healthier.

The study suggests vitamin D may help to slow down the ageing process of DNA, and therefore the ageing process as a whole.

Lead researcher Dr Brent Richards said, "These results are exciting because they show for the first time that people who have higher levels of vitamin D may age more slowly than people with lower levels of vitamin D." This could help to explain how vitamin D has a protective effect on many ageing related diseases, such as heart disease and cancer."

Professor Tim Spector, a co-author of the report, added, " Although it might sound absurd(荒唐的), it's possible that the same sunshine which may increase our risk of skin cancer may also have a healthy effect on the general ageing process.

Vitamin D made by the action of sunlight on the skin accounts for 90 percent of the body's supply, but lower levels can also be got through food such as fish, eggs and breakfast cereals(粥).

Other studies have suggested the vitamin plays a key role in protecting against cancer and heart disease.

C. the higher levels of vitamin D people have, the more slowly people may age

D. vitamin D can only be got from fish, eggs and breakfast cereals
