第十一章 复杂句的基本认知
一、什么是复杂句
复杂句是另一种更长的句子
复杂句由主句和从句构成
主句和从句都有自己的主语+动词结构
主句可以自己独立存在，从句不能自己独立存在
二、常用的复杂句连接词
because, after, before, when, as soon as, if
三、复杂句的语序
一般情况下，主句在前，从句在后，连接词在从句开头，
不需要逗号断开
John is hungry now because he did not eat lunch.
从句也可以放在前面，需要逗号与主句断开
Because John did not eat lunch, he is hungry now.
如果句子里有名词和代词，则名词先出现，代词后出
现，不管前面的是主句还是从句
John is hungry now because he did not eat lunch.
Because John did not eat lunch, he is hungry now.
四、使用because表示原因
以because开始的从句叫原因从句
原因从句里的动词可以是过去、现在或将来
原因从句放在句首，要用逗号和主句断开
Because the car was expensive, Pablo did not buy it.
Pablo did not buy the car because it was expensive.
五、使用 after、before、when 和 as soon as 表示时间
after、before、when 和 as soon as 表示从句和主句的时间关系
以 after、before、when 和 as soon as 开始的从句叫时间从句
时间从句放在句首，要用逗号和主句断开
Before Omar went to the airport, he packed his suitcase.
Omar packed his suitcase before he went to the airport.
六、使用if表示条件
if开始的从句用于给出主句的条件
以if开始的从句叫条件从句
条件从句放在句首，要用逗号和主句断开
If we have extra time, we want to play basketball.
We want to play basketball if we have extra time.
重要考点：主将从现
与将来有关的时间从句和条件从句，主句使用will或be going to，从句使用一般现在时
第十二章 名词性从句的作用
一、名词性从句
名词：人物、事物、地点，可以做主语或宾语
英语句子：一组词，有完整含义，有主语，有动词
从句：由引导词开始的句子，不能脱离主句独立存在
疑问词：提出问题的词，如who/whom,what,whose，
which,when,where,why,how,how many,how much,how often 等
名词性从句就是一个从句作为名词，由that、疑问词或if/whether 引导
注意:
1、名词性从句视作单数名词，动词需要使用单数
How often people change careers __is__ (be) an interesting question.
2、that 从句作宾语时，that 可以省略
Research suggests (that) salty food is harmful to your health.
3、注意名词性从句中主语和动词的顺序
错误 They are not sure who is he.
正确 They are not sure who he is.
名词性从句常见错误
1、从句中主语和动词的顺序
2、从句视作单数名词，作主语的从句与动词保持一致
二、名词性从句的作用
1.提出想法和观点
Jean Piaget, a Swiss psychologist, believe that the thinking process in children is different from that in adults.
2.描述发现和具体情况
Scientist find that English learning in childhood is beneficial.
Recent studies show that generous people are generally happier than others.
3.给出建议或推荐（应用）
Health experts recommend that adults should get between seven and eight hours of sleep each night.
