题目内容
________ to sunlight for too much time will do harm to one’s skin.
A．Exposed B．Having exposed C．Being exposed D．After being exposed
C
【解析】
试题分析：句意：在阳光下暴晒很长的时间对你的皮肤是有伤害的。expose的宾语后常可接介词to表示“将…暴露于…”; 动词宾语为oneself时,则意为“将自己暴露于…”“使自己受某人的影响”。 那么它的被动的短语就是be exposed to,又因为这里是做主语的所以用be 的动名词形式。故选C。
考点：考查非谓语动词的用法。
点评：本题难度适中。非谓语动词是近几年高考的热点，本题是对已学知识点的回顾，需要考生能够理解该题的语言环境，进而作出正确的判断。会判断非谓语动词与它的逻辑主语之间是什么关系，需要考生掌握非谓语动词的不同形式的用法区别等。
即学即练：I still remember_______to the Famen Temple and what I saw there.
A. to take B. to be taken C. taking D. being taken
解析D 。 考查非谓语动词。此处非谓语动词做remember的宾语，而remember后用非谓语动词做宾语时，可以用v-ing形式，v-ing表示的动作已经完成，也可用动词不定式，表示的动作还未发生，根据后文的saw可知此处非谓语动词动作已经完成，且与逻辑主语是被动关系，用v-ing的被动式，选D。

Vitamin D helps bones and muscles grow strong and healthy. Low levels of vitamin D can lead to diseases such as rickets (佝偻病), mainly found in children. The thinning of bone is a common problem as people, especially women, get older.
But more and more research is suggesting that vitamin D might also help prevent many diseases. The easiest way to get vitamin D is from sunlight. The sun’s ultraviolet (紫外线的) rays react with skin cells to produce vitamin D. But many people worry about getting skin cancer and skin damage from the sun. As a result they stay out of the sun. Also, darker-skinned people produce less vitamin D than lighter-skinned people. The amount also decreases in older people and those living in northern areas that get less sunlight.
Not many foods naturally contain vitamin D. Foods high in this vitamin include oily fish and fish liveroils (鱼肝油). Farmed fish have only about one-fourth as much vitamin D as wild fish. Small amounts of vitamin D are found in beef liver, cheese and egg yolks. But most of the vitamin D in the American diet comes from foods such as milk.
Research in the last several years has shown that low levels of vitamin D may increase the risk of heart attacks in men and deaths from some cancers. More doctors are now having their patients tested for their vitamin D levels. But as research continues, some experts worry that if people take too much vitamin D, it might act as a poison. Also, skin doctors warn people to be careful with sun exposure because of the risk of skin cancer.
