5. The particular design of muscles and bones in the neck and limbs of the turtle allow

A.   allow that it can draw in its exposed parts such that

B.    allow it to draw in its exposed parts, and so

C.   allows for it to draw in its exposed parts and that

20. In 1981 children in the United States spent an average of slightly less than two and a half hours a week doing household chores; by 1997 they had spent nearly six hours a week.

A.   chores; by 1997 they had spent nearly six hours a week

B.    chores; by 1997 that figure had grown to nearly six hours a week

C.   chores, whereas nearly six hours a week were spent in 1997

D.   chores, compared with a figure of nearly six hours a week in 1997

E.    chores, that figure growing to nearly six hours a week in 1997

答案是B. 如何排除A呢？ they的指代应该也挺明确的是children.

(A) allow应该用第三人称形式；such that所表达的是强调含义，与so that表达目的的含义不同。

(B) allow应该用第三人称形式；and与so都是连词，重复。

(C) and that没有并列对象；for多余，固定搭配是allow sb to do sth。

(D) and与so都是连词，重复；allows that it can draw的表达方式不及allow to do简洁。

(E)  正确，allows与单数主语design一致，so that引导目的状语从句。
