1.B,He asked if we___swim 这句是并与从句,if翻译成“是否我们会游泳”,时态和主句保持一致,would是愿意的意思,意思是“如果我们愿意去的话,他会教我们”
2.B.意思是“从那个小岛上挖掘出来的硬币其中的三分之二追溯于公元前221年”
dug up on the island 作后置定语修饰the coins.
date from意思是追溯于...

应该是选b
意识是，被挖出来的三分之二的钱币都有追溯到公园前221年的历史。

是愿意的意思。情态动词的用法。还有一些特殊的比如should,有时候有竟然的意思，must有偏巧的意思。
第二题选D，因为coins是复数。还有。题目应该是TWO-THIRDS吧。。。几分之几分子大于1，分母就是负数

1 可以理解为意愿、
2 d 因为coin是复数

第一题选 B，（多说一句，我觉得asked后面应该是if吧） 因为第一个由于asked的时态是过去式，决定了后面从句的时态，即can的过去式could（从offered也可以看出）。后面应该是如你所说的“愿意”的意思。
第二题选 B，这里主语是“Two-third of the coins”，且是复数主语“dug up on the island”是修饰主语的后置定语，因此缺少谓语。但是date from这个词组是Vt，用主动式，意思为“回溯到(开始于,从...的时候存在)”，可以参考例句：
Eg：The history of public education in the United States dates from the society of the early pioneers.
美国的公共教育史起源于早期拓荒者的社会。
综上可以看书答案选B

b d

1.选B：could,would
would是愿意的意思
2.选B：date
翻译成：在这个岛上挖掘的硬币中，三分之二的硬币可以追溯到公元前 221年。
这里date是指“源自：有过去特定时间的起源”，组成短语 date from,表示“可以追溯到...”
又如：This statue dates from 500b.c.

He asked his mother where it happened 和He asked his mother how it happened到底那个句子正确 When asked why he did it,he simply said ,‘Because I love it.’ when asked about it,he says nothing/he said nothing.哪个时态对的啊 Was it because he was ill ____ he asked for leave? 应该选哪一个?为什么 Then he asked his father ____he could do it as he do. 应该填什么? you asked for it! you asked for it he asked for a glass of beer.but they had drunk all of it 翻译 直接引语转间接引语He asked,How did you find it,mother? I think it is ugly （he asked me） 改为宾语从句 he asked,how did you find it,mother?改为间接引语 He asked how much I thought it would costRT 这句话表述对吗? 分析It’s curious that he should have asked such a question he would have asked you about it这是什么句式啊,写了 when asked why he did it不是应该when doing sth么 He ____ me his watch and asked me what I thought of it.
