2、语。其意思为 孤单eg, He feels lonely. (作表语)2. 作定语，修饰表示处所的名词。eg, The old man lives in a lonely mountain village.注意： alone 强调客观上的 独自。单独一人, 而lonely除表示单独外，还带有感情色彩，形容失去朋友，缺乏友爱和帮助，感到寂寞、甚至悲哀，它只能做形容词，在句中做表语，也可做前置定语，用于地点时，意为 荒凉的，偏僻的eg, Though the old man is alone, he doesnt feel lonely二、probably adv. 很可能，或许，大概eg, Pr

3、obably he may know the way. (放句首)He is probably about 50 years old. (放在系动词后面)I probably didnt try hard enough. (放在谓语前面)Itll probably rain. (放在助动词后面)able adj. 1. 有能力的，能干的eg, My father is an able engineer.2. 用于be able to 结构，后跟动词原形。eg, Jim isnt able to come tonight because he is ill.三、be able to 与can ：

4、相同 点：两者后跟原形动词。区别：1. can是情态动词，无人称与数的变化。过去式是could.be able to 可与情态动词连用，can却不能。eg, I shall be able to speak English well.2. be able to 可用在不定式之后，而can却不能。eg, I hope to be able to go shopping with you on Sunday.3. be able to 的过去式还有表示过去经过努力而做到的意思，而could 没有这种意思。eg, He studied hard and was able to pass the ex

5、am.4. can 表示请求和允许，以及猜测，而be able to 却无此用法。eg, Mr Smith cant be at home. Can I carry your bag?5. 当表示现在或过去的能力时，两者可通用。eg, No one was able to/could answer the question.2、in 与 after的区别in是指以现在时间为起点的“在一段时间以后”。也可以表示“在将来多少时间之内”，句子中的谓语动词要用一般将来时态；after常指以过去时间为起点的“一段时间之后”，所以它与过去时态连用。当after指某个特定的未来时刻或日期之后，或指以将来某一

6、时间为起点的若干时间之后时，它可以与将来时态连用。 例句：Ill be back in half an hour. 我半小时后就回来.本句中的in作以后解，不能用after代替。after和in都可以表示以后的意思，其区别是：1）after以过去为起点，表示过去一段时间以后，常用于过去时态的句子。例如：They started working after lunch. 他们是午餐后开始工作的。The film was shown after the meeting. 电影是会议结束以后放的。2）in以现在为起点，表示将来一段时间以后，常用于将来时态的句子。如：They will start w

7、orking in half an hour. 他们将在半小时后开始工作。The film will be shown in 2 or 3 days. 这部电影将在两三天后上映。3）在某个特定的时间以后，after也可用于将来时态的句子。例如：They will start working after 10 am. 他们将在上午10点以后开始工作。The film will be shown after 5 oclock. 这部电影将于4点以后上映。4) “after+一段时间”或“一段时间+later”表示“（在过去某个时间看来）一段时间之后”。He went home after two

(2)fall off:从上掉下来e.g. Mary fell off the ladder last night.（3）fall in love with(4) fall over4、every day与everyday区别：every day名词短语，表示“每天”，通常与一般现在时连用；

9、而everyday形容词，表示“日常的，每天发生的，每日所用的”。例如：I get up at six every day. 我每天6点起床。He wears everyday clothes today今天他穿一身便服。Wear、put on、have.in的区别wear表示“穿”，表示状态，用一般现在时表示经常状态，用现在进行时表示暂时状态。egWe wear our rain boots on a rainy day. 我们在下雨天穿雨鞋。She is wearing a new coat 她穿着一件新衣服。Does he wear glasses? 她戴眼镜吗？put on是“穿上”，

10、“戴上”的意思，强调动作。egShe put on a red coat and went out. 她穿上红色大衣出去了。 注意：put on是一时的动作，不能跟表示一段时间的状语连用。他整天戴着草帽。 误：He puts on a hat all day. 正：He wears a hat all day5、. be worth doing值得；be worthy of doing, be worthy to do值得6、Seem的用法：1)seem to do似乎He seems to think so.2)It seems that看来It seems that he is lying

Suchthat和sothat都可用来引出一个结果状语从句。由于such是形容词，所以that从句前有一个受such修饰的名词；而so 是副词，用以修饰形容词或副词，因此that从句前一般不出现名词。如They are such kind-hearted t

13、eachers that people in the village all respect them.

28、数形式要跟there be之后的真正的主语一致。并且要根据就近一致原则来变换be的单复数形式。如：There is a book on the desk.课桌上有一本书。 How many people are there in the city?这个城市里有多少人口。There is a pen and two books on the desk.课桌上有一个钢笔和两本书。3. 在therebe引起的句子结构中，用来修饰主语的不定式主动形式和被动形式均可。 There is no time to lose(= to be lost).时间紧迫。 There is nothing to see

30、in your factory.（公共汽车不一定属于我们厂所有） Our factory has a bus.（公共汽车属于我们厂所有）2）句型不同。there be句型为“There be +某人（物）+某时（地）”；have 句型为“某人（物）+have(has)+某物（人）。如There isnt a cat under the chair. She doesnt have two brothers.3)当表示某物的构成和组成部分时，用there be和have 均可。如，Our school has sixty classes.= There are sixty classes in

31、our school.我们学校有60个班。【注意】there be句型中有两个或多个并列主语时，须根据就近原则，be与最靠近的主语在数上保持一致。如，There are two eggs and a cup of milk on the table.There be句型的将来时表达方式:肯定：There will be否定：There wont be一般疑问句：Will there be.? Yes, there will. No, there wont.课堂小考场1I. 用 lonely 或 alone填空：1. Dont leave the baby _ at home.2. When h
