4、t.fight for “为而斗争”，后面常接抽象名词，表示为事业、自由等而斗争。E.g. They are fighting for freedom. 他们正为自由而战。fight against “为反对而战斗”，后接事物名词、人和国家名词。E.g.

5、已婚女子姓前。 Madam：也用于已婚女子，意为“夫人、女士”，一般单独使用，不与姓连用Miss.：“小姐”用于未婚女子姓前，还常用于年轻的女教师的姓前，可译为“老师”。3. 【辨析】 get to/reach/arrive 都表示“到达”不同点：get to+地点；reach+地点 arrive at+小地点（车站等）；arrive in+大地点（国家等）【解析】get to与地点副词（here/there/home）不用介词toE.g. I want to go to Beijing. I got home at 15:00. arrive是不及物动词，后面若接地点名词则要和in/at连用

6、，接地点副词时则不用介词。E.g. I arrived home at 15:00. = I got home at 15:00. He arrived in Shanghai yesterday. reach是及物动词，后面直接接地点名词或副词。E.g. When will they reach here?4. 【辨析】意义例句on time“准时，按时”，不早不晚He always go to school on time.in time“及时”Fireman reached the house on fire in time.5. 【辨析】意义和用法例句hear “听说”，侧重于听的内容

7、I never heard such an interesting story. Im sorry to hear that you are ill.listen“听”，侧重于听这一动作The children like to listen to music.

8、he classroom?bring“带来”，指把东西从别处带到说话地。E.g. Bring your homework here tomorrow, please.5. 【辨析】wear, put on, dressinwear是动词，表示“穿”，强调状态。E.g.

13、either.too用于肯定句句末，用“，”隔开I like dancing, too.also用于肯定句句中，动词前I also like English.12. have fun=have a good time=enjoy oneself 表示“玩得开心，过得愉快”E.g.

We have to wear sneakers（运动鞋）for gym class. Tom has to practice

19、the guitar every day. I had to get up at 5:00 am last Monday. 否定形式：主语+dont have to+动词原形+其他一般现在时：主语是第三人称单数时用doesnt have to, 其它时候用dont have to （过去时：无论人称和单复数都用didnt have to） E.g. Nick doesnt have to wear a uniform. We didnt have to do our homework at once. 疑问句：Do, Does或Did+主语+have to +动词原形+其他 E.g. Do y

20、ou have to stay at home on weekends? Yes, I do. / No, I dont. Did he have to go to bed by 11:00 last night? 2. 情态动词must的用法must表示说话人的主观看法，及主观上的必要性，还用于命令或愿望。只用于现在时，无人称和单数的变化。在表示过去、将来和完成时，用have to的相应形式来代替must.在表示有做某一个动作的必要和义务，它的意思是“必须，应该”。E.g. You must finish your homework first.表示有很大把握的判断或者推测，意思是“一定，准

21、是”。E.g. The tall man must be your father.以must开头的一般疑问句，它的否定回答用neednt（不必要），不用mustnt（不允许），mustnt常用于否定句中表示“不允许，禁止”。E.g. Must I go there on foot? No, you neednt. You mustnt park your car here.3.情态动词can的用法表示能力：“会；能”， E.g. Can you play the guitar? Judy can speak a little Chinese. I can dance and sing. 表示允

22、许、许可：“可以；能”E.g. Can the students run in the hallways（走廊）? We can eat outside. Can I come in? 【注】同样是情态动词can 和have to 的用法是有区别的，和大部分情态动词一样，can在否定句中直接在can后加上not；在疑问句中把can放到主语前面，并且没有人称和数的变化，而 have to 是有相应变化的。 4. 祈使句（Imperative Sentence）定义：用于表达命令、请求、劝告、警告、禁止等的句子叫做祈使句，祈使句最常用于表达命令，因此有时也常称为命令句。祈使句因对象（即主语）是第二

23、人称，所以通常都省略。祈使句的动词都为一般现在时，句末则使用句号或感叹号来表示结束。祈使句的肯定句：行为动词原形+其他E.g. Go and wash your hands. 去洗你的手。命令 Be quiet, please.= Please be quiet. 请安静。请求 Be kind to our sister. 对姐妹要和善。劝告 Watch your steps. 走路小心。警告 Look out！Danger！ 小心！危险！强烈警告 Keep off the grass. 勿践草坪。禁止 No parking. 禁止停车。禁止以Let开头的祈使句，Let后宾语是是第一人称时，否

24、定形式是在宾语后加not,E.g. Lets not do that again.我们别再那样做了。 如果Let 后面宾语是第三人称，否定形式是在Let前加助动词Dont,E.g. Dont let them come in.别让他们进来。祈使句的否定通常使用“Dont ”，Dont+动词原形（行为动词/be动词）+其他言字旁：认、语、诗、谁、请、许、说、话E.g. Dont let the dog in.坐和座 跟和根 在和再 像和象 相和向 做和作 美和没 Dont touch（触摸）, please. Dont be silly.（14）自己学会（生活）的本领，才能成为（真正）的狮子。祈

25、使句有时也把主语“You”表达出来，使对方听起来觉得柔和些名（有名）（出名）（名字）（成名）（名气）各种句式的掌握原（草原）（平原）（高原）（原来）（原因）E.g. You go and tell him, Chris. （3）两只鸟蛋就是（两只小鸟）。我（小心）地捧着鸟蛋，（连忙）走到树边，轻轻地把鸟蛋（送还）。我仿佛（听见）鸟儿的欢（唱），抬起头来，把（目光）投向（高远）的蓝天。宽宽的门 大大的窗 红红的苹果宝盖头：完、家、定一（块）石头 一（匹）骏马 一（杆）大称 四（根）柱子（左） （右） 旧（新） （冷）（热） 甜（苦）（21）取人之（长），补己之（短）。（2）、（ ）正（ ）呢！T
