几道英语选择题求解

According to the American federal government, residents of Hawaii have the longest life ________:77.2 years.
A. rank

B. scale
C. span
D. scope
为什么选C. span不是动词吗？句子已经有动词have了其他选项为什么不行
if you had told us earlier he was ,we could habe introduced him at the meeting
Awho Bwhom Cwhich Dthat
选什么，答案选A，但是who whom不是不能在定语从句中做表语吗？ 我觉得应该选which

Answer 1

C
span 最长的生命周期
根据美国联邦政府的资料，夏威夷居民的寿命最长达到77.2岁。
scope指范围，范畴，领域等；rank指等级、阶级；scale指刻度，比例，数值范围等。

第二题，不是仅仅看是哪一个，还要看意思。如果表达，我不知道她是谁，你岂不是没法说出来了，就是I do not know who she is.

是宾语从句而不是定语从句。宾语从句可以是由who引导的。

Answer 2

1 the longest life span :77.2 years.

选C. span不是动词 是名词 life span 是寿命的意思
=the span of life .
其他选项就不用说了吧。
if you had told us earlier who he was ,we could have introduced him at the meeting
Awho Bwhom Cwhich Dthat
答案选A，这是宾语从句 不是定语从句 who 能在宾语从句中做表语
不应该选which。which指人不妥。

Answer 3

life span 是寿命的意思；span也是名词，意思是 跨度；范围。所以选 C
who 是对人的连接代词，这里指得是人，当然用who，这个好像没有什么争议的。

谢谢！
