高一英语定语从句last week,only two people ame to look at the house,(

C.none of whom
Last week,only two people came to look at the house.None of them wanted to buy it.
复合：Last week,only two people came to look at the house,none of whom wanted to buy it.
宾格代词them用关系代词whom替换,对应先行词two people.none of whom置于从句之首.
特此修正
A.After which
He was educated at the local high school.He went on to Beijing University after it.
复合：He was educated at the local high school,after which he went on to Beijing University.
it用关系代词which替换,对应先行词school.After which置于从句之首.
因为有介词after,所以不能用that,只能用which.
D.where
sight是名词：“视觉”,在从句中作主语.
matter是不及物动词：“有关系,重要”,在从句中作谓语.从句中主语谓语俱全,因此排除which.
Those deaf dancers think that dancing is an activity.Sight matters more than hearing in the activity.
复合：Those deaf dancers think that dancing is an activity where sight matters more than hearing.
in the activity用关系副词where替换,where置于从句之首.
意为：那些失聪的舞者认为,舞蹈是一种让人看胜过让人听的活动.
where可以指明确的具体的"地点",也可指模糊的抽象的"地点"——"情形"、"场景"、"阶段",此句为后者.
A.whose
Don't get close to the house.Its roof is under repair.
复合：所有格its用关系代词whose替换,对应先行词house（whose既可指人也可指物--house）.
Don't get close to the house,whose roof is under repair.
B.setting up
主句：He wil devote all to ____ some schools for children.
定语从句：(that) he had
固定搭配：devote something to sth./doing something 把…奉献给
他将把他所有的一切都奉献出来为学童创建学校.
He wil devote all (that) he had to setting up some schools for children.
