23. My brother while he his bicycle and hurt himself.
A.fell; was riding
B. fell; were riding
C.had fallen; rode
D. had fallen; was riding

答案是A 为什么后面有and hurt 前面的动词不与hurt一致?

31. ——Good morning. Can I help you?

——I’d like to have this package,madam.
A.be weighed
B. to be weighed
C. to weigh
D. weighed

答案是D 虽然有have sth done 但是不是衡量单位measure、weigh没有被动吗?

36. All is needed is a supply of oil.
A.the thing B. that C. what D. which
求详细解释………………谢谢

Answer 1

23..时态一致 hurt-hurt-hurt 过去式和过去分词一致 且while后+sb be doing(表示时间段) 他过去正在骑自行车是过去的事，所以用一般过去时。
31.weigh无被动，have something done表示某一状态，和被动没有关系
36.句子后有两个动词，所以考虑到从句，又因为all的特殊性和结构，用which

Answer 2

个人理解：
第一题：时态是一致的。Hurt动词原形与过去时是相同的。
My brother fell while he was riding his bicycle and hurt himself.
弟弟跌到一般过去我相信你是明白的，后面was riding 也是过去时态，表示他过去正在骑自行车
weigh确实没有被动，但是短语就可以使用被动，例如：sell是不及物动词，但是短语sell out
就可以使用被动，如All of goods have been sold out in the past 3 months.
36题。all后面的是定语修饰词，但是ALL已经可以作为主语，所以that or which,但考虑到all的特殊性，应该which
all the thing 后面接are (not is)
