不定式
不定式在句中可作主语、表语、宾语、定语、状语、宾语补足语等。
1. 不定式可作主语。如：
To be calm in danger is very important/significant.
不定式作主语时, 往往用it作形式主语, 而把不定式后置, 即: It + be +形容词/名词/介词短语+不定式；It +动词+宾语+不定式。如：
It is necessary for us senior students to learn English well before entering a university.
It is a pity to give it up when it is nearly completed.
I’m sorry, it is beyond my power to answer the question.
It takes me half an hour to ride to school in the mornigng rush hour.
2. 不定式可作表语，说明主语的具体内容。如：
My chief purpose is to point out the difficulties of the matter.
3. 不定式可作宾语, 其逻辑主语常常是句子的主语。常见的后可接不定式作宾语的动词有: want, hope, wish, offer, fail, plan, learn, pretend, manage, agree, promise等。
如：I want to know what happened to Norman.
Jennie hopes to prevent anything unpleasant from happening again.
不定式作动词宾语时, 如果后面有宾语补足语, 常用it作形式宾语, 而将真正的宾语（不定式）放在宾语补足语的后面。如：
He found it very difficult to get accustomed to getting up so early before, but I did finally manage.
4. 不定式可作定语，通常放在其所修饰的名词或代词之后，这时不定式与其所修饰的名词或代词在逻辑上可能是主谓关系，也可能是动宾关系。如：
You need to help your kids answer this question.
Do you have some clothes to take to your son today
5. 不定式可作状语，表示目的、结果等。如：
They got up very early in the morning to get there in time.
He went to the station in a hurry, only to be told the train had gone.
6. 不定式可作宾语补足语，与宾语是逻辑上的主谓关系。常见的后可接不定式作宾语补足语的动词有：advise, allow, ask, beg, cause, encourage, expect, force, invite, order, teach, tell, want, warn等。如：
The compromise will allow him to continue his free market reforms.
We encourage all members to strive for the highest standards.
感官动词(如feel, see, hear, watch, notice等)和某些使役动词(如make, let, have等)后常跟不带to的不定式作宾语补足语。当这些动词用于被动语态时，不定式符号to不可以省略。如：
Did you happen to see her leave last Wednesday

______________________________________________
It is not easy to manage stress successfully. When you are stressed, every problem you have seems become worse. Serious stress can also lead to health issue, such as dizziness, skin conditions, and breathing problems. So that is best to find a solution as soon as possible. For
minor stress, to wash your face with cold water or go for a short walk outside. To fight long-term stress, it is a great idea taken up a new hobby. Do something you really like — to ride a skateboard, go bowling, or watch a comedy — whatever stimulates your mind and makes you feel happy. Absorbing stress effectively, however, you must be sure to do something that completely takes your mind off everything else. If you can find something else to concentrate for a while, you will most certainly feel much more refreshed later on. So remember, to free yourself from stress, try and find something positive replace it with. After all, it is far too stressful to stress all the time!

6 Which do you think is more important for bringing out the benefits of laughter, the act of laughing or the social interaction connected to it What are your reasons
Adults don’t necessarily remember how to make fun.
According to research, laughter also has a direct and positive effect on our blood vessels.
When you have 5-10 minutes of laughter you can burn up to 40 calories.
It means that when someone is laughing, we are more likely to laugh too.
She will stop doing it.
I think that the social interaction connected to laughter is more important for bringing out its benefits, because laughter is a social thing and happens when people are communicating with each other. It is harder to laugh and be happy when we are alone.
