几道英语问题
1.A good friend of mine from when I was born showed up at my home right before I left for Beijing. 这句话是什么结构、什么意思啊
2.She will never forget _A_she found her son who had gone missing two years before.
A.that B.where
为甚么不选where?还有“forget her stay here”是……感觉怎么看都不对啊?还有这句话的结构能否分析一下,到底是谁引导谁、谁修饰谁?
3.I will give you my friend's address,_B_I can be reached most evenings.
A.which B.where
为什么选where?后半句是什么意思?
4.All the neighbors admire this family _B_ the parents are treating their child like a friend.
A.that B.where
为什么是where不是that
5.The doctor advised me to live _B_the air is fresher.
A.in which B.where
为什么不能用in which
6. The journey around the world took the old sailor nine months,_A_ the sailing time was 226 days.
A.of which B.during which
为什么不选B
7.last week our english teacher set so difficult an examination problem _A_none of us worked out.
A.as B.which
为什么不选B

翻译：一个自我出生之时起就是我好朋友的人,就在我动身前往北京之前,出现在我家中.
1.句子主语是a good friend of mine,谓语是showed up,at my home为地点状语,而right before I left for Beijing为时间状语从句.
句子主干为：A good friend of mine showed up.
2.而from when I was born为介宾短语做后置定语,修饰句子主语a good friend of mine.
其中的when I was born为介词from的的宾语从句,两者一起构成一个介宾短语.
句意为“从我出生的时候开始起”,即该宾语从句中缺失一个时间状语,所以其引导词用when.
二、
应该that 和where 都可以选,选 that 就是宾语从句,发现她的儿子两年前失踪这个作为忘记的宾语.如选where ,就是不会忘记发现她儿子两年前失踪的地方（特殊疑问句）作为宾语从句.
而加上 her stay here
句子中 she will never forget her stay here.是主句,主谓宾俱全,所以由where引导一个定语从句,修饰地点先行词there.where在定语从句中作地点状语.
三、
be reach 被拿到?方正做adress的非限制定语肯定是选where
四、
定语从句中,不缺成分的,你见过用that的吗?当然用 where ,表在这样一个家庭中怎样怎样.
五、
主句缺成分（宾语）,空气清新的地方作为宾语.宾语从句吧.
如果要改,应为The doctor advised me to live in the place where the air is fresher.
这时where the air is fresher.作为定语从句.做the place 的定语.
而你说的用 in which .The doctor advised me to live in which the air is fresher.如此是不对的.
如此用,which 意为代替了从句中的成分,而句子并没有.
六、
.The journey around the world took the old sailor nine months,_A_ the sailing time was 226 days.
A.of which B.during which
B根本说不通嘛.
照A来说,先行词是nine months.在从句中用which代替.非限制定语从句还原就是 the sailing time was 226 days of which(nine months),只是 of which 提前了,
七、
.last week our english teacher set so difficult an examination problem _A_none of us worked out.
A.as B.which
为什么不选B
可以看出,从句none of us worked out.后却宾语,先行词就是 an examination problem
so as 式的定语从句 固定用法.
PS 楼上第七题错解,如果用that的话,那 none of us worked it out.(要加it)
解释不明白的追问.
这么多问题才5分.你也太扣了吧.嘿嘿.
再问： 第5个能否写成The doctor advised me to live in the place in which the air is fresher? (嘻嘻，我是先设定5分，如果答得好了再加分的）
再答： 严格来说也不算错，我觉得没必要这样。 你想想 ，还原句子，live in the place ,the air is fresher in the place.关键这里前面有个in 了，再来一个就很奇怪了。 还是简单点好，也可以写成 The doctor advised me to live where the air is fresher.
