5、more than / less than分別可以理解為“多于/少于”,相當(dāng)于副詞,more than=over; less than=under.如：I lived in New York for more than four months.(我在紐約生活了四個(gè)多月)
6、“one of the +最高級+名詞(復(fù)數(shù))”整個(gè)短語為單數(shù)含義,謂語要用單數(shù)形式。如：One of the oldest houses has been burnt in a fire.(最古老的一幢房子在一場大火中被燒毀了)
7、“Which / Who+動(dòng)詞+形/副,□,□or□?”句型中,如果有兩個(gè)選項(xiàng),形/副用比較級,如果有三個(gè)選項(xiàng),形/副用最高級。如：Who has more books, Lin Tao or Han Mei?(林濤和韓梅誰的書最多？)/ Which is the heaviest,a pig,a horse or an elephant?(豬、馬、象哪個(gè)最重？)
8、上下文中含有both/either/neither/two/twins等表示兩個(gè)事物的詞時(shí),用比較級,而且往往還要加the；含有all/none/no one/ every 等表示三個(gè)或三個(gè)以上事物時(shí),用最高級。如： --Do you like the smaller one?—Neither.(小一點(diǎn)的那個(gè)你喜歡嗎？一個(gè)都不喜歡)/ --Which do you like best? ?All of them!(你最喜歡哪個(gè)？全部。)
七、介詞：
1、介詞的主要用法：
介詞是一種虛詞,不能獨(dú)立使用。介詞之后一般有名詞或代詞(賓格)或相當(dāng)于名詞的其他詞類、短語或從句作它的賓語,即構(gòu)成介詞短語。有些介詞是由兩個(gè)以上的詞構(gòu)成的短語介詞,如：out of(從…中出來), because of(因?yàn)?, away from(距離…), on top of(在…頂上), ever since(自從…), next to(在…隔壁), according to(根據(jù)…), in front of(在…前方)等。
2、介詞的分類表： (見下表)

3、介詞短語的句法作用：
介詞短語相當(dāng)于一個(gè)形容詞或副詞,可用作狀語、定語和表語。如：The man came
4、在句子中的位置：
介詞短語做狀語時(shí),如果表示時(shí)間/地點(diǎn),可以放在句首或句尾,如果表示方向/方式/伴隨/涉及/原因/目的/比較,一般放在句尾； 介詞短語作表語時(shí)放在連系動(dòng)詞之后；介詞短語作定語時(shí),只能放在被修飾的名詞之后。如：He wanted to find a good job in Shanghai the next year.(狀語)(他想來年在上海找份好工作)/ They searched the room for the thief.(他們在房間里搜索小偷) / The letters are for you.(表語)(信是給你的)/ Have you seen a cat with a black head and four white legs?(定語)(你看見一只黑頭白腿的貓了嗎？)
5、重要注釋：
⑴ this / that / these / those / last / next / a / every / each等詞構(gòu)成的時(shí)間短語,前面不用任何介詞。如：Every year travellers from abroad come to visit Pingyao.(每年都有國外的游客來游覽平窯鎮(zhèn))/ He had a bad cold that week.(那個(gè)星期他患重感冒)
⑵ for有時(shí)用來引出動(dòng)詞不定式的邏輯主語,常翻譯成“對于…而言”。如：It’s too hard for me to finish the work in only one hour.(讓我在區(qū)區(qū)一個(gè)小時(shí)內(nèi)完成這項(xiàng)工作太難了)/ The house is big enough for 10 men to live in.(房子夠大的可以容10個(gè)人住)
⑶ of有時(shí)用來表示后面的人物正好是前面的表語的邏輯主語。如：It’s very nice/kind of you to do so.(你這么做真是太好了)
⑷ 介詞有時(shí)會(huì)與它的賓語分離,而且賓語前置。
① 當(dāng)賓語是疑問詞時(shí)。Who are you talking about?(你們在談?wù)撜l？)
② 賓語在從句中當(dāng)連接詞時(shí)。He has a younger brother who he must take good care of.(他有 一個(gè)需要他照顧的小弟。) / Do you know who our teacher is talking with over there?(你知道我們的老師在那邊和什么人談話嗎？)
③ 動(dòng)詞不定式作定語且該動(dòng)詞為不及物動(dòng)詞,后面有介詞。I finally found a chair to sit on.(我 最終找到了一張椅子坐。)
(5) 記住一些固定詞組：arrive at/in(到達(dá)…),on foot(步行),not…at all(根本不),to the north of(在…以北),in the east of(在…的東部),in the night(在夜間),at night(在晚上),be afraid of(害怕…),be full of(充滿/ 裝滿….),be filled with(充滿/ 裝滿….),be good/bad for(對…有益/有害),be made of(由…做成),be made from(由…制造),play with(玩耍……),look out of(朝…外面看),at the end of(在…末梢/結(jié)束時(shí)),by the end of(不遲于…/到…末為止),with the help of或with one’s help(在…的幫助下),look after(照料…),look for(尋找…),on a bike(=by bike)騎車, help sb. with(幫某人做…),get on (well) with(與某人相處[融洽]),等等。

⑴ 時(shí)間或地點(diǎn)介詞in、on、at的用法區(qū)別：表示時(shí)間時(shí), in表示在一段時(shí)間里(在將來時(shí)句子中則表示在一段時(shí)間之后), on表示在具體的某一天或者某天的上下午等, at表示在某個(gè)時(shí)刻或者瞬間； 表示地點(diǎn)時(shí), in表示在某個(gè)范圍之內(nèi), on表示在某個(gè)平面上或與一個(gè)面相接觸,at則表示在某個(gè)具體的場所或地點(diǎn)。如：He was born on the morning of May 10th.(他出生于五月十日的早晨)/ I usually get up at 7：00 in the morning.(我通常在早上的七點(diǎn)鐘起床) / His glasses are right on his nose.(他的眼鏡就架在他的鼻子上)/ He is at the cinema at the moment.(此刻他正在電影院)

⑹ through與across、over的用法區(qū)別： through指“穿過…(門洞/人群/樹林)”； across和over可以指“跨越…(街道/河流)”,可互換,但是表示“翻過…”時(shí)只能用over. 如：Just then a rat (鼠)ran across the road.(就在那時(shí)一只老鼠跑過路面)/ There is a bridge across/over the river.(河上有座橋)/ They climbed over the mountain and arrived there ahead of time.(他們翻過大山提前到達(dá)了那里)/ The visitors went through a big gate into another park.(參觀者們穿過一個(gè)大門來到另一個(gè)公園)

★重要注解：
(1) 關(guān)于實(shí)義動(dòng)詞：
① 英語的實(shí)義動(dòng)詞又可分為及物動(dòng)詞和不及物動(dòng)詞兩大類：
后面必須跟賓語意義才完整的叫及物動(dòng)詞；本身意義完整,后面不需跟賓語的叫不及物動(dòng)詞。
② 有些動(dòng)詞通常只作不及物動(dòng)詞。如：go,come,happen,lie,listen,rise,arrive,hall等。
有些動(dòng)詞通常用作及物動(dòng)詞。如：say, raise, lay, find, buy等。
③ 大多數(shù)動(dòng)詞可以兼作及物動(dòng)詞和不及物動(dòng)詞。如：study, sing等。
④ 有些動(dòng)詞作及物動(dòng)詞與作不及物動(dòng)詞時(shí)的意義有所不同。如：know, wash等。
⑤ 有些動(dòng)詞常和介詞 、副詞或其它詞類一起構(gòu)成固定詞組,形成短語動(dòng)詞。如：listen,reply,wait,look.
(2) 關(guān)于連系動(dòng)詞：
① 連系動(dòng)詞用來連接主語和表語,連系動(dòng)詞后面常為形容詞。
② 常見的連系動(dòng)詞有：be、become、look、feel、sound、smell、taste、seem、turn、grow、get、 go、fall、sit、stand、lie 等。
③ 有些連系動(dòng)詞來源于實(shí)義動(dòng)詞,意思也跟著變化：look(看→看起來)、feel(感覺、摸→感到)、 smell(聞、嗅→聞起來)、taste(嘗→嘗起來)、turn(翻轉(zhuǎn)、轉(zhuǎn)動(dòng)→變得)、grow(生長→變得)、get(得到、到達(dá)→變得)、go(去→變得),所不同的是,作為實(shí)義動(dòng)詞時(shí),后面不能跟形容詞。
[注釋]
become、get、go、be、grow、turn的用法區(qū)別：become表示“變成”,比較正式,通常不用將來時(shí)表示動(dòng)作已經(jīng)完成。get也表示動(dòng)作已經(jīng)完成,但是更加口語化,通常表示溫度、時(shí)間、歲數(shù)等變化。go表示“變得”,常見于某些短語中,后面常有形容詞bad、blind、hungry等。be表示“是、成為、當(dāng)”,多用于將來時(shí)、祈使句或不定式中。grow表示“變得”,常指逐漸的變化,表示身高、歲數(shù)的增長。turn表示“變得”,指變?yōu)榕c原先不同的情況,通常指顏色等變化。如：I was caught in the rain and I became ill.(我淋雨感冒了)/ He has got rich.(他變富了)/ He will be a scientist in the future.(將來他將成為科學(xué)家)/ My little brother has grown much taller in the past year.(在過去的一年里我的弟弟長得高多了)/ The sandwich has gone bad.(那塊三明治已經(jīng)變壞)/ Her face turned red after her mother criticized(批評) her.(媽媽批評了他以后他的臉變紅了)
(3) 關(guān)于助動(dòng)詞：
①常見的助動(dòng)詞有：用于進(jìn)行時(shí)和被動(dòng)語態(tài)的be (am, is, are ,was, were, been, being ) ;用于完成時(shí)的have(has,had,having) ;用于將來時(shí)的shall (should) ; will (would)和用于一般時(shí)的do(does,did) .
②助動(dòng)詞必須同主語的人稱和數(shù)一致,也就是說因主語人稱、數(shù)的不同而采用不同的形式,其中有些助動(dòng)詞也可作情態(tài)動(dòng)詞。如：shall, will, should, would.
(4) 關(guān)于情態(tài)動(dòng)詞：
①常見的情態(tài)動(dòng)詞有：can (could) ,may (might), must ,shall (should), will (would), dare (dared) , need等,另外,have to、had better也當(dāng)作情態(tài)動(dòng)詞使用。情態(tài)動(dòng)詞后面必須加動(dòng)詞的原形。
②can表示體力、腦力方面的能力或客觀的可能性�？谡Z中, 在詢問或說明一件事可不可以做時(shí),常用“can”代替“may”。情態(tài)動(dòng)詞“can”的過去式是“could”,否定式是“cannot”通�？s寫成“can’t”,“could”的否定式是“could not”,通�？s寫成“couldn’t”。如：Can I help you?(要幫忙嗎？)/ He can swim.(他會(huì)游泳)/ That can’t be Mr Li.(那不可能是李先生)
③ may表示允許、請求或可能性,用may提問時(shí),肯定回答一般用Certainly或Yes,you may.;否定回答一般用can’t或mustn’t. 如：May I ask you a question?—Certainly.(可以問你一個(gè)問題嗎？當(dāng)然可以)/ You may go now.(現(xiàn)在你可以走了)/ It may be in your pocket.(它可能在你的衣袋里)
④ must表示“必須”、“一定”的意思。表示“必須”時(shí)否定形式是mustn’t；表示“一定”時(shí),否定形式是“can’t” 如：We must be very careful when we cross the road.(我們過馬路時(shí)一定要非常小心)/ It must be Jack.(那準(zhǔn)是杰克)/ I haven’t seen Kate today. She can’t be here.(我今天沒有看到過凱特,她不可能在這里)
[注意]用must(必須)進(jìn)行提問時(shí),肯定回答用must,否定回答用needn’t；用must(一定)進(jìn)行提問時(shí),肯定回答仍用must,但是否定回答用can’t.如：Must we clean the room before we leave? ?Yes,you must.或No,you needn’t.(我們走之前必須要打掃房間嗎？是的,必須打掃。/ 不,不需要。) / Must she be in the romm? ?Yes,she must.或No,she can’t.(她一定在房間里嗎？是的,一定。/ 不,不可能在。)
⑤ “have to”表示“不得不”、“必須”。We’ll have to leave now for it is very late at night.
have to的疑問形式是：助動(dòng)詞+…+have to,否定形式是：助動(dòng)詞+not+have to或者用needn’t.如：Do you have to stay until 8 o’clock?(你得呆到8點(diǎn)鐘嗎？)/ You don’t have to do so.(=You needn’t do so.)(你不用這么做)
⑥ shall在問句中,可表示征求對方意見,與第一人稱連用；在陳述句的第二、三人稱的主語后或表示“命令”、“警告”、“允許”等。如：Shall we go to the zoo this weekend?(我們這個(gè)周末去動(dòng)物園好嗎？)/ He shall bring his own book next time.(他下次必須帶自己的書來)
⑦ should可表示“勸告”、“建議”、“驚奇”等意思。We should speak to old people politely.(我們應(yīng)該禮貌地對老人講話)
⑧ will表示“意愿”、“決心”等意思,一般與第二人稱連用。如：Will you please close the door for me?(請你替我把門關(guān)上好嗎？)/ I will teach you a lesson.(我要教訓(xùn)你一頓)
⑨would表示過去的“意愿”、“決心”等。He would sit near the fire every time he returned home.(每次他回到家中總要坐在火爐邊)
would也可以表示現(xiàn)在的情況,表達(dá)說話人向?qū)Ψ教岢龅囊?語氣比“will”婉轉(zhuǎn)、客氣。在日常會(huì)話中,“我想要…”通常用“I would like to”或“I should(I’d) like to”來表示。如：Would you like to have a rest at the moment?(你現(xiàn)在想要休息一下嗎？)
would還可以表示過去經(jīng)常發(fā)生的事情。如：Every year parents would tell their children about the boy who would save his people.(每一年父母們總是向孩子們講述這個(gè)將會(huì)拯救他的人民的男孩的事)
⑩ need表示“需要”,用于疑問句或否定句�！皀eed”作實(shí)義動(dòng)詞時(shí),在肯定、否定、疑問句中都可以用。如：He needn’t do it in such a hurry.(他不需要如此匆忙地做這件事)/ He needs some help.(他需要一些幫助)/ He doesn’t need to bring his football socks then.(那么他就無須帶上足球襪了)
⑾ dare是“敢”的意思,用法幾乎與“need”完全相同,即在疑問句和否定句中,可以作情態(tài)動(dòng)詞,后面用不帶“to”的動(dòng)詞不定式。在肯定句中和實(shí)義動(dòng)詞一樣,后面的動(dòng)詞不定式要帶“to”。How dare you say I am a fool?(你竟敢說我是個(gè)傻瓜？)/ He didn’t dare to touch the red button.(他不敢觸碰那個(gè)紅色的按鈕)
⑿ ‘d better (do)(“最好是”)一般也當(dāng)作情態(tài)動(dòng)詞使用,否定式是：’d better not (do). 如：You’d better sit here and say nothing.(你最好坐在這兒不講話)/ You’d better not speak because he is sleeping.(你最好不要講話因?yàn)樗谒X)
