◆定语从句中关系代词只能用that和不能用that的几种情况：
只能用that的情况
1. 先行词是不定代词。
例句：Please tell me everything that happened to you.
2. 先行词被形容词最高级、序数词或only, last, same, very等修饰。
例句： ①This is the most interesting movie that I have ever seen.
②This is the only book that I read during the summer holiday.
3. 先行词既包括人又包括物。例句：She talked about the writer and his works that interested her.
不能用that的情况
1. 非限制性定语从句中。
例句：He said he could speak three foreign languages, which is not true.
2. 先行词本身是that。
例句：I have that which you gave me.
3. “介词+ 关系代词”结构。
例句：The person to whom I talked just now is Tom.
◆现在完成进行时与现在完成时进行的比较：
1. 强调动作还未结束时， 多用现在完成进行时；强调动作的结果时， 多用现在完成时。例句：
①I have been painting the paining. （强调“一直在画”这个动作）
②I have painted the painting. （强调“画完了”这个结果）
2. 有些动词不能用在现在完成进行时中，但可用在现在完成时中。如：have, love, see等。例句：
①She has had a cold for a week.
②They have loved each other for three years.
③I have seen this movie.
-ing形式：
1. having done
having done是非谓语动词中-ing形式的完成式，而doing则是其一般式，它们都与句中主语构成逻辑上的主谓关系，只是doing与句中谓语动词同时发生或基本上同时发生；having done则表示动作或状态发生在句中谓语动词之前。
[例句]
①Hearing the news, they got excited. （hear 和get excited这两个动作几乎同时发生）
②Having arrived at the top of mountain, they took a rest. （arrive 发生在take a rest之前）
2. 动词后接动词的-ing形式和不定式有些动词后既可接动词的-ing形式也可接to do形式作宾语，但意义有所不同。
[例如]
① forget / remember / regret doing sth. 表示动作已经发生；
forget / remember / regret to do sth. 则表示该动作未发生。
② mean to do sth. 表示“打算做某事”；
mean doing sth. 表示“意味着做某事”。
③ try to do sth. 表示“设法尽力做某事”；
try doing sth. 表示“试着做某事”。
④ stop to do sth. 表示“停下来接着做另一件事”；
stop doing sth. 表示“停止做某事”。
⑤ go on to do sth. 表示“（做完某事）接着做另一件事”；
go on doing sth. 表示“继续做同一件事”（= go on with sth.）。
⑥ can’t help to do sth. 表示“不能帮助做某事”；
can’t help doing sth. 表示“情不自禁地做某事”。
3. have/has been doing
have / has been doing是现在完成进行时的构成，强调动作的延续过程，动作可能还在进行。而have / has done是现在完成时的构成，强调动作的结果，该动作通常已经结束。
[例句]
①I have written a book. （动作结束）
②I have been writing a book. （可能未写完，侧重最近一直忙于写书）
