3.The traffic rule says young children under the age of four and____less than 40 pounds must be in a child safety seat.
A.being weighed
B.to weigh
C.weighed
D.weighing

Answer 1

1.选择C。
实验表明：如果定期进行适量的练习，可以使我们更健康
是一个省略句，原为if it is carried out regularly……可以将it is（主语，系动词）删除，it代表的是exercise……

2.选择B。
这道题bring about 缺宾语，在选项中what 可以做bring about的宾语。
这句话的意思是："尽管两千位患者在服用，但是这种药的副作用还没有确定。”

3.选择D
交通法规规定：4岁以下并且少于40磅的小孩必须坐在儿童安全坐位上。可以看AND前后并列，前面under the age of 4做young children 定语，后边也应该是做young children 定语。加上注意时态其实一般现在时。

望采纳。
