late意思是"晚"； lately 意思是"最近"

deep意思是"深"，表示空间深度；deeply时常表示感情上的深度，"深深地"

high表示空间高度；highly表示程度，相当于much

考点名称：不定式

• 动词不定式：
  指由to加上动词原形（而且只能是动词原形）所构成的一种非限定性动词，但在有些情况下to可以省略。
  动词不定式在语法功能上可作主语、宾语、宾语补足语、表语、定语和状语。

• 动词不定式可以作以上各种成分，但它毕竟是动词，所以有动词的属性。
  动词不定式及其短语还可以有自己的宾语、状语，虽然动词不定式在语法上没有表面上的直接主语，但它表达的意义是动作，这一动作一定由使动者发出。
  这一使动者我们称之为逻辑主语，其形式如下：
  

  时态	主动形式	被动形式
  一般式	(not) to do	(not) to be done
  完成式	(not) to have done	(not) to have been done
  进行式	(not) to be doing
  完成进行式	(not) to have been doing

• 不定式的用法:
  1、不定式作主语
  例如：To remember this is very important.
  注意：为了避免头重脚轻，在许多情况下，通常都将作主语的不定式置于句子后部，而在句首主语位置使用形式主语it。
  例如：It is very important to remember this.
  2、不定式作表语
  例如：He seems to be ill.
  注意：不定式作表语主要有三种情况，一是用于seem, appear, prove等系动词之后的不 定式（尤其是to be），
  二是像My job is to sweep the floor. 这样的主语与表语“等价”的情形，
  三是表示想法、约定、义务、命令、可能性、命运等，如： 
  You are to come when I call.
  3、不定式作宾语
  例如：I can not afford to buy a car.
  注意：
  ①不定式不仅用作动词的宾语，还可用作个别介词（but, except）的宾语。
  例如：I had no choice but to wait.
  ②当作宾语的不定式后跟有宾语补足语时，通常要用形式宾语it代替不定式，并将真正的宾语不定式置于宾语补足语之后
  例如：I find it difficult to learn Japanese well.
  4、不定式作宾语补足语
  例如：Who taught you to drive?
  5、不定式作定语
  例如：I have a question to ask you.
  注意：有的名词（如way, chance, right等）后用作不定式可换成of doing sth.
  如：It is the best way to do (of doing) it.
  但是以下名词后接不定式作定语时通常不能换成of doing sth.
  attempt  courage  decision  effort  fortune  failure  invitation  wish
  6、不定式作状语
  例如：I went to France to learn French.
