　　About 80% of people 65 years and older have living children, and about 90% of them have _ ____(29)contact with their children. About 75% of elderly parents who don't go to nursing homes live within 30 minutes of at least one of their children.

　　However, __ ___(30)having contact with children does not guarantee happiness in old age.

This research may be __ ___(31), however, as ill health often makes older people more _ ____(32)and thereby increases contact with family members. So it is more likely that poor health, not just family involvement, __ ___(33)spirits.

A.abandoned  B.advanced  C.biased  D.chances

E.commitment  F.dampens  G.dependent  H.distant

I.frequent  J.fulfillment  K.grant  L.merely  M.provide

N.understandably O.unrealistically

26. provide

解析：本空应该填一个谓语动词，备选项中符合条件的只有grant和provide，而grant是授予、承认，用在这里语义予不合逻辑，所以只能选provide。provide sth to sb 提供给某人某物，也可以说provide sb with sth.

27. abandoned

解析：从语法看，本空应该填一个形容词来做feel的表语，备选项中有六个形容词；再看语义，父母不和孩子生活在一起也不会感到被抛弃，所以应该选abandoned。

28. frequent

解析：从语法来看，本空仍然要填一个形容词，have____ contact with，结合语义应该用frequent。

29. merely

解析：从语法上看这个空格所在的句子主干完整，因此句首应该填个副词，从备选项中的副词进行选择，再结合上下文语义应该用merely。

30. biased

解析：这个空格处应该填写个形容词，从语义上来说填biased更恰当，表明这个研究可能是片面的。

31. dependent

解析：先利用语法知识，将答案锁定在形容词中，再看哪些形容词还没有被选过；再看空格之后的and thereby表结果；and thereby之后的内容是与增加与家人的交往；and之前应该是疾病使得老人变得没那么独立。这里形成了一套因果关系，因为疾病使老人变得需要依靠，从而增加了老人与家人的交流。

32. dampens

解析：根据语法这里需要一个谓语动词，而且是一个单三的动词，符合条件的只有dampens，而且dampens spirits 和上一句的have the lowest spirits形成了衔接。

33. commitment

解析：空格应该填个名词，religious commitment 宗教信仰，其他名词填写到这里不合符语义逻辑。

34. understandably

解析：从语法上看，空格所在句子主干结构完整，因此本空只能是填个副词做状语。这句话的意思是：对于这些事情的分歧会引发父母与子女之间的问题，这也是可以理解的。

35. chances

解析：从语法角度来看，这里只能填写名词；且chances are that …… 是固定搭配，意为 ……是有可能的。
