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 do morning exercise every day is good for our health.
不定式作主语时, 往往用it作形式主语, 而把不定式后置,
如：
It is important for us to wear the safety belt when driving a car.
It is a pity to be kept in the house in such fine weather.
It is beyond my power to answer the question.
It takes half an hour to walk there.
2. 不定式可作表语，说明主语的具体内容。如：
My work is to clean the room and water the flowers every day.
3. 不定式可作宾语, 其逻辑主语常常是句子的主语。常见的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 don’t want to leave my hometown.
Jennie hopes to give her daughter a good education.
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 necessary to take more clothes when travelling.
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：
We need someone to help with the work.
I have a lot of letters to write today.
5. 不定式可作状语，表示目的、结果等。如：
They started early to get there in time.
He hurried to the station only to find 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：
They don’t allow the children to use the knife.
My success encouraged me to continue.
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：
I saw him leave a few minutes ago.
You may take a horse to the water, but you can’t make it drink.
He was seen to leave a few minutes ago.
We were made to work all night.

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.

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!
