Question

关于下面三个英语句子的提问。

1.Who is it that had the computer on the whole night?
2.Only those (whom) he knew very well could be given a free ride.
3.That who breaks the law will be punished.
问题：1.这三句句子分别都是什么句？
2.第2句句子中“whom”为什么可以省略？

Answer 1

1、带定语从句的特殊疑问句

Who(表) is(谓) it(主) that had the computer on the whole night(定语从句)?

注意这个定语从句的语法：that(关系代词，代替先行词it，在从句中作主语) had(谓语) the computer(宾语) on(副词做宾补) the whole night(状语)

2、带定语从句的陈述句

Only(限定性副词) those(主语) whom he knew very well(定语从句) could be given(谓语) a free ride(宾语).

注意这个定语从句的语法：whom(关系代词，代替先行词those，在从句中做动词knew的宾语，可省略) he(主语) knew(谓语) very well(状语)

3、带定语从句的陈述句

That(主语) who breaks the law(定语从句) will be punished(谓语).

注意这个定语从句的语法：who(关系代词，代替先行词That，在从句中作主语) breaks(谓语) the law(宾语)

Answer 2

1强调句的疑问句
2定语从句
3 这个我不清楚 因为我觉得That的用法是错的 好似不能做主语 用He好些（不管男女）

定语从句that who 等可省略

Answer 3

都是定语从句关系代词whom在句中做宾语可省略

Answer 4

1.强调句的疑问句。陈述句型是it is sb that had the computer on the whole night.去掉强调句式是sb had the computer on the whole night.
2. whom引导的定语从句修饰those，whom是定语从句he knew very well 的宾语，可以省略。定语从句的引导词做宾语时（可以为that，who，whom）可省略
3. 此句错误，去掉that，who引导的是主语从句，违反法律的人将被惩罚。用whoever是最佳答案

Answer 5

1强调句（把who提前变疑问句，原句应该是：It is who that had the computer on the whole night?
2定语从句
3主语从句
第二问中those who（whom）是表示“一类人”those whom作knew得宾语，所以可以省（个人理解）

Answer 6

这三句分别是 强调句 强调句 主语从句

第二句whom做从句的宾语 定从中先行词如是充当宾语则可以省略
