　　今天小编为备考的同学们整理了英语四级that的用法辨析，希望可以为大家带来帮助，预祝大家高分通过，和小编一起来看看吧！
　　英语考点归纳：that
　　A complicating factor is that merit aid has become so popular v}rith middle-income families, who don't qualify for need-based aid，that many have come todepend on it.
　　英语四级译文:
　　一个复杂的因素是，奖学金已经受到那些不符合助学金条件的中等收入家庭的欢迎，很多人开始依赖奖学金了。
　　四级词汇讲解:
　　本句的主干是factor is that。句中第 一个that引导的是表语从句;该表语从句中包含so...that…的句型结构，其中that引导的是结果状语从句;而两个逗号之间who所引导的是middle-income families的非性定语从句。
　　become popular with的意思是“受……的喜爱，欢迎”，也可以说be popular with。如: This young teacher is popular with students.这位年轻的老师很受学生的喜爱。
　　qualify for的意思是“有资格，有权(要求)”。如: He doesn't qualify for unemployment benefit.他没有资格获得失业救济金。
　　come to do sth.的意思是“逐渐开始做某事”。如: They have finally come to believe that.他们终于开始相信那件事了。
　　depend on的意思是“依靠，依赖”。如: Children always depend on their parents，孩子们总是依赖父母。
　　英语四级考点归纳:
　　so...that...意为“太，以至于”，常用句型为“主语 谓语 so adj./adv. that从句”，以so... that...引导的结果状语从句可以转换成带不定式的简单句，即可转换为...enough to...或too...to...句型，但这种转换必须符合下列条件:

　　 当主句和从句的主语一致，且that从句是肯定句时，可用...enough to...来替换。如: The man is so strong that he can lift the heavy box.=The man is strong enough to lift the heavybox.这个人非常强壮，可以抬起很重的箱子。
　　当主句和从句的主语不一致，且that从句是肯定句时，可以用...enough for sb. to do sth.来替换，但须注意不定式的宾语要省略。如: The question is so easy that I can work it out.=The question is easy enough for me to work out.这个问题很容易，我能解答出来。
　　 当主句和从句的主语一致，且that从句是否定句时，可以用too...to...来替换。如: I was so tired that I couldn't go on with the work.=I was too tired to go on with the work.我太累了，没法继续工作。
　　当主句和从句的主语不一致，且that从句是否定句时，如果要用too...to...替换so...that... ,需用介词for引出动词不定式的逻辑主语，即用too...for sb. to do sth.来替换，注意不定式的宾语要省略。如: It is so hot that we can't sleep. = It is too hot for us to sleep.天气太热了，我们无法入睡。
