后者是一个动词短语，“努力工作”hard 是副词，修饰动作work.
eg. Alice works hard.
2. forget to do 与forget doing…
前者是“忘记做……”(to do 表示将来的动作)
e.g. Don’t forget to call me.别忘了打电话给我。

后者是“忘记曾做……”(通常与will, shall, never连用)
eg. I’ll never forget seeing the musical in New York.我永远忘不了在纽约看过的那出歌舞喜剧。
【重难点分析】
直接引语和间接引语
（一）直接引述别人的原话，叫做直接引语；用自己话转述别人的话，叫做间接引语。间接引语一般构成宾语从句。直接引语必须放在引号内，间接引语则不用引号。直接引语改为间接引语时，除将引语部分变成宾语从句外，还必须对直接引语中的人称、时态、指示代词、时间状语、地点状语等进行改变。
1. 时态的变化：直接引语变为间接引语时，通常受转述动词said，asked等的影响而使用过去化的时态，即把原来的时态向过去推，也就是一般现在时变为一般过去时，现在进行时变为过去进行时等。
例如：
Tom said to me,“My brother is doing his homework.”
→Tom said to me that his brother was doing his homework.
2. 人称代词、指示代词、时间状语、地点状语等等的变化；根据意义进行相应的变化。
例如：
She asked Jack, “Where have you been?” →She asked Jack where he had been.
He said, “These books are mine.” →He said that those books were his.
（二）直接引语改为间接引语时，都使用陈述语序，但是因为原句的句式不同，所以变成间接引语时所用的连词会有所不同。
1.陈述句的间接引语
陈述句由直接引语变间接引语，通常由that引导，可以省略。
“I want the blue one.” he told us. “我想要蓝色的。” 他说。
→He told us that he wanted the blue one.他说他想要蓝色的。
She said to me, “You can’t settle anything now.”她对我说：“此刻你无法解决任何事情。”
→She told me that I couldn’t settle anything then.她对我说那时候我无法解决任何事。
2. 疑问句的间接引语
直接引语如果是疑问句，变成间接引语后，叫做间接疑问句。间接疑问句为陈述语序，句末用句号，动词时态等的变化与间接陈述句相同。引述动词常用ask, wonder, want to know, inquire。间接疑问句一般有三种：
(1)．一般疑问句由直接引语变为间接引语时，由whether或if 引导。
如：
“Has he ever worked in Shangha i?”Jim asked. “他在上海工作过吗？”吉姆问。
→Jim asked whether/if he had ever worked in Shanghai. 吉姆问他是否在上海工作过。
“Can you tell me the way to the hospital?” The old man asked.
那个老人问：“你能告诉我去医院的路吗？
→The old man asked whether I could tell him the way to the hospital.
那个老人问我是否能告诉他去医院的路。
(2). 特殊疑问句由直接引语变为间接引语时，仍由原来的疑问词引导。
如：
“Which room do you live in?” He asked.“你住哪个房间？”他问我。
→He asked me which room I lived in. 他问我住哪个房间。
“What do you think of the film?” She asked. 她问“你怎么看这部电影？”
→She asked her friend what she thought of the film.她问她的朋友怎么看这部电影。
(3). 选择疑问句由直接引语变为间接引语时，由whether/if …or引导。
如：
“Is it your bike or Tom’s? Mum asked. 妈妈问：“这是你的自行车还是汤姆的？”
→Mum asked whether/if it was my bike or Tom’s.妈妈问这是我的自行车还是汤姆的。
“Does your sister like blue dresses or green ones?” Kate asked.
“你妹妹喜欢蓝色的裙子还是绿色的？”凯特问。
→Kate asked whether/if my sister liked blue dresses or green ones.
凯特问我的妹妹喜欢蓝色的裙子还是绿色的。
3. 祈使句的间接引语
当祈使句变为间接引语时，间接祈使句的引述动词常用tell，ask，order，beg，request，order等，而把直接祈使句变成带to的不定式短语。
如：
Jack said, “Please come to my house tomorrow, Mary.”杰克说：“玛丽，明天请到我家来。”
→Jack asked Mary to go to his house the next day.杰克请玛丽第二天到他家去。
The teacher said to the students,“Stop talking.”老师对学生们说：“不要讲话了。”
→The teacher told the students to stop talking.老师让学生们不要说话了。
“Don’t touch anything.” He said.“不要碰任何东西。”他说。
→He told us not to touch anything.他对我们说不要碰任何东西。
4. 动词时态和代词等的变动
(1). 某些代词，限定词，表示时间或地点的副词和个别动词在间接引语中的变化规则如下：
直接引语间接引语
today that day
now then, at that moment
yesterday the day before
the day before yesterday two days before
tomorrow the next day / the following day
the day after tomorrow two days after, / in two days
next week/ month etc the next week/month etc
last week/ month etc the week / month etc. before
here there
this that
these those
come go
bring take
(2). 如果引述动词为现在时形式，则间接引语中的动词时态，代词，限定词和表示时间或地点的副词不用变化。而如果引述动词是过去时，以上内容就要有相应变化。变化情况如下：
现在时间推移到过去的时间，即一般现在时变为一般过去时；
“I feel better today.” He said.“我今天感觉好多了。”他说。
→He said that he felt better that day. 他说他那天感觉好多了。
现在进行时变为过去进行时；
“Xiao Ming is doing some washing” Mum said. “小明正在洗衣服。”妈妈说。
→Mum said that Xiao Ming was doing some washing.妈妈说小明正在洗衣服。
