U8 T2语法讲解
宾语从句（Ⅲ）疑问词引导的宾语从句
1.宾语从句的引导词
what，who，whose，which，why.hen，where，how等连接词引导。
Tell me what you want.
告诉我你想要什么。
2.宾语从句的语序
宾语从句的语序必须是陈述句语序，尤其要注意whether/if和wh-连接词引导的宾语从句的语序，即按照“主语+谓语…”的语序。如：
Is he good at English 他擅长英语吗？（一般疑问句，疑问句语序）
Can you tell me if he is good at English 你能告诉我他是否擅长英语吗？
（宾语从句，陈述句语序）
Why is winter colder than summer 为什么冬天比夏天冷？（特殊疑问句，疑问句语序)
Do you know why winter is colder than summer 你知道为何冬天比夏天冷吗？
（宾语从句，陈述句语序)
句型It is+adj./that从句
在英语中，如果一个句子作主语(即主语从句)，由于主语（从句）较长，为了使句子平衡，通常把主语放在整个句子的后部，把“”放在最前边，作形式主语，即形成It is+adj.+that...句型。
It is important that you study English well.

“It is+adj.+that从句”句型有时可以用It is+adj.+for sb.to do sth.句型来改写。如：
It’s impossible that we finish it in half an hour.
=It’s impossible for us to finish it in half an hour.
半小时完成工作对于我们来说是不可能的。

=It is necessary for us to have different kinds of clothes.
