（这句话时态为一般过去时）
【其中some time/money 为具体的时间或金钱】
2.in order to+动词原形=in order that+从句=so that+从句“目的是；为了”，可放在句中或句首。

否定结构为：in order not to do sth.
e.g.：In order to catch the early bus，she gets up early.
=She gets up early in order to catch the early bus.=She gets up early so that she could catch the early bus.
=She gets up early in order that she could catch the early bus.

as a result of ...=because of...“由于……；作为……的结果”，后常接名词、代词、动名词。

since“从……以后；自……以来”，引导时间状语从句。

主句用完成时从句用一般过去时。

三、书面表达
本单元写作话题是帮助父母做家务杂务的正反观点，因此题裁为议论文。

议论文通用模板为引-议-联-结，即引用题干给出的问题或争议观点，对观点展开议论并用论据证明自己的观点，然后联系现实，最后进行总结并扣题。

要学会运用should和shouldn't，it's+adj for/of sb (not) to do 这一结构表达自己的观点,此外，可以运用Firstly, secondly, finally做为陈述论据的开始，用all in all 做为总结以增加文章层次和条理性。

参考下边有关家务的范文：
Some people think students needn't to do any housework. I disagree, do you know why?
It's good for students to do some housework. There are three reasons. Firstly, doing some housework can make you independent. You can't depend on others all the time. Secondly, doing some housework can keep you healthy and strong. Finally, it's not enough to just get good grades at school. As a member of the family, everyone should do their part in keeping our house clean and tidy.
All in all, I believe it's good for students to do some housework. The earlier students learn to do the housework, the better it's for their future.。
