Sample Writing
Everyne gets excited by the news f the mst recent space flights, and I t share in peple's sense f awe and wnder at the phts frm space that we see. Having said that, it is hard t believe that the high cst f space flight is justified s that we can get sme lvely pictures.

Space Explratin is a Waste f Time and Mney
little as a dllar a day, a child in Africa can be saved. Cnsidering the billins spent n space travel, it just seems a better investment t feed the hungry.Sme peple argue that smeday we will have t g live in space because the wrld will be made impssible t live inthrugh pllutin. This seems silly. When yur huse gets dirty, yu spend the time and mney t clean it up. Yu dn't mve huse simply because yu need t wash yur windws r vacuum the flr. In the same way, it makes mre sense t use ur time and mney t take care f ur planet, rather than lk fr a new hme.Finally, there are a lt f unslved mysteries n the earth. S why are we ging int space t explre? There are still
many things t discver in the cean depths and the Antarctic. But we d nt even have t g that far: Science has yet t unlck all the mysteries f the atm, and there are many realms f technlgy that we are just beginning t understand and explre.In the end, it just des nt seem a very wise investment t g t space. We have t many needs here n the earth t be wasting ur effrt n space explratin.

目的状语：置于句首或句末，为加强语气，常与in rder或s as组成短语。
※ 不定式作目的状语时， 其动作通常迟于谓语动词的动作。
例：I said that t encurage him.
1. I walked quietly s as nt t disturb the baby.我安静地走路，以免打扰婴儿。
2. 目的状语：置于句首时只用t d/in rder t d.如用于表示否定，in rder或s as不能省略，用in rder nt t d或s as nt t d形式。
He wrked very hard t pass the exam.=He wrked hard s that/in rder that he culd pass the exam. 他非常努力以便能通过考试
3. 不定式作目的状语可转换为s that/in rder that引导的目的状语从句
