1. 我经常怀疑是否值得花如此多的时间在家庭作业上。

Step 2 Grammar
We use a question word to introduce an object clause that expresses a wh-question. The word order in the clause should be the same as that in a statement.
Whom is an object pronoun. We can use who instead of whom.
1. I wonder what I should do.
2. Daniel does not know whom he should talk to.
3. Sometimes we forget when we should stop.
4. I do not understand why they are so strict with me.
5. I do not know how I should deal with the problem.

Step 6 Giving suggestions
We give suggestions politely using structures such as Why not…, Why don’t you,…, What/ How about…, Let’s… and Shall we…
Tip:
We also use perhaps to give suggestions. Perhaps you should manage your time better.
e.g. 1. Why not eat less and exercise more
2. Why don’t you let your parents know you need them
3. What/How about choosing your hobby according to the time you have
4. Let’s write a letter to Mr Sigmund Friend.
5. Shall we have a meeting about this
我们可以用
Why not… What/How about… Let’s…和Shall we…等提建议。
Perhaps 也可用于建议。
e.g. Perhaps you can park over there.
(1) 句型Why not… 是Why don’t you … 的缩略形式，“为什么不……？”“你为什么不…… ”,后面跟动词原形。
e.g. Why not donate your pocket money to charity
你为什么不将零用钱捐给慈善组织？
=Why don’t you donate your pocket money to charity
(2) 句型What/How about … “……怎么样？” “……如何？”，后面跟名词，代词或者动名词。
e.g. What/How about having a cup of coffee 喝杯咖啡怎么样？
(3) 句型let’s …“让我们……吧”，后面接动词原形。
e.g. Let’s listen to the teacher. 让我们听老师讲吧。
句型Shall we … 意思是“我们……好吗？” 后面跟动词原形。
e.g. Shall we go swimming tomorrow 我们明天游泳好吗？
