语法精讲精练
if 或 whether 引导的宾语从句
我们可用 if 或 whether 引导宾语从句，此时从句部分的语义相当于一个一般疑问句。如：
I want to know if/whether he is our new teacher. 我想知道他是不是我们的新老师。
◆ 连词 if 和 whether 意思是“是否”，在从句中不充当句子成分，在口语中多用 if。如：
Tom wonders if/whether his grandpa will come next week.
汤姆想知道他的爷爷下周是否过来。
◆ 宾语从句的语序必须是陈述句语序，即“连接词 + 主语 + 谓语 + 其他成分”。如：
“Did Mary clean the classroom yesterday ” Mr Hu is asking.
→ Mr Hu is asking if/whether Mary cleaned the classroom yesterday.
胡老师在问昨天玛丽有没有打扫教室。
◆ 宾语从句中的人称代词要符合逻辑，有时需进行合理变化。如：
She wonders, “Can I be a great scientist like Yuan Longping when I grow up ”
→ She wonders if/whether she can be a great scientist like Yuan Longping when she grows up. 她在想自己长大后能不能成为一位像袁隆平那样伟大的科学家。
“Can you help me ” she asks.
→ She asks if/whether I can help her. 她问我能不能帮助她。
连接代词和连接副词引导的宾语从句
我们可用连接代词或连接副词引导宾语从句，此时从句部分的语义相当于一个特殊疑问句。如：
We do not know whose pencil this is. 我们不知道这支铅笔是谁的。
Nobody knows when the train will arrive. 没人知道火车什么时候会到。
注意：常见的连接代词有 what、who、whom、whose、which，连接副词有 when、where、how、why。
◆ 连接代词和连接副词有词义，且在从句中充当句子成分。如：
Can you tell me what they are doing 你能告诉我他们在做什么吗？
(what 在从句中做宾语，意思是“什么”)
◆ 宾语从句的语序必须是陈述句语序。如：
She wants to know why that little boy is crying. 她想知道那个小男孩为什么哭。
◆ 宾语从句中的连接代词 who 与 whom 都指人，意思是“谁”。其中 who 为主格，在从句中做主语；whom 为宾格，在从句中做宾语。如：
I do not know who is playing the piano next door. 我不知道谁在隔壁弹钢琴。
Can you guess whom/who my father is talking with
你能猜猜我爸爸正在和谁谈话吗？
注意：whom 在口语中很少使用。大多数情况下，我们可以用 who 代替 whom。
◆ 含有宾语从句的复合句的标点由主句决定。如：
I am not sure if/whether the bag is big enough. 我不确定这个包是否够大。
Can you tell me which bus I should take 你能告诉我该乘哪路公共汽车吗？
