A．pulsive　　　　　　　　 B．pulsory C．demanded D．claimed 解析：選B　pulsive強(qiáng)迫性的；情不自禁的；作“強(qiáng)迫的”時(shí)，指一般的外力所迫使；demanded被強(qiáng)烈要求的，強(qiáng)調(diào)有權(quán)利或需要堅(jiān)持得到，有時(shí)表現(xiàn)出一種跋扈專橫；claimed合理要求的，強(qiáng)調(diào)有權(quán)或宣稱有權(quán)得到所需要的；pulsory指法律或規(guī)章的強(qiáng)制性，義務(wù)教育是法律規(guī)定的。因此B項(xiàng)正確。 [短語(yǔ)精析] 1．be determined to do“決定/心做某事”，為系表結(jié)構(gòu)，著重于有決心的狀態(tài)，可與表示一段時(shí)間的狀語(yǔ)連用。 He is determined to bee a teacher. 他決心當(dāng)一名教師。 I am determined to do better than Mike. 我決心比邁克做得更好。 determine to do sth.　　　　　 [動(dòng)作]決定做某事 determine that ... 決定…… He determined to set out early.他決定早點(diǎn)動(dòng)身。 　 　 He started working hard at his lessons，________to get the first place.

A．introducing B．introduced C．introduce D．being introduced 解析：選B　主句的主語(yǔ)與從句的主語(yǔ)都是these products，所以從句可用省略形式。主語(yǔ)與introduce之間為邏輯上的動(dòng)賓關(guān)系，所以應(yīng)用過(guò)去分詞。 2．There_seemed_to_be_nowhere_to_hide but then he noticed lots of seaweed on his left and quickly hid under it. 似乎是沒(méi)有地方可以藏身，但是后來(lái)他注意到在他的左邊有一些水草并且他迅速地藏在了水草下面。 There seems/appears to be...看起來(lái)好像有…… There seems to be something wrong with it. 它好像有點(diǎn)兒毛病。 there be結(jié)構(gòu)中可以加上一些詞表示特殊的意義，類(lèi)似的還有： There must be...　　　　 一定有 There may be... 可能有 There happens to be... 碰巧有 There used to be... 過(guò)去常有 There is going to be... 將要有 There will be... 將會(huì)有 There is said/reported(/...)to be... 據(jù)說(shuō)/報(bào)道(……)有…… What a pity my new puter doesnt work.There must be something wrong with it. 很遺憾，我的新電腦不好用了。它一定是壞了。 There happens to be a mistake.碰巧有一個(gè)錯(cuò)誤。 there be句型中容易出錯(cuò)的地方： (1)不能用has或have代替there be句型中的be。 (2)there being結(jié)構(gòu)在句中作狀語(yǔ)，相當(dāng)于一個(gè)狀語(yǔ)從句，因此主句中就不再用任何連詞。 There being no bus, we had to walk home. ＝There was no bus, so we had to walk home. 沒(méi)有公交車(chē)了，因此我們只好步行回家。 　 　 (1)There has a baby over there. ________________________________________________________________________ (2)There being no further business，so the chairman closed the meeting. ________________________________________________________________________ (3)There is report to be a number of the wounded on both sides. ________________________________________________________________________ 答案：(1)has改為is　(2)去掉so　(3)report改為reported 3．He had not_only an outstanding ability in navigation and exploration，but_also a real concern for sailors health.他不但有杰出的航海和探險(xiǎn)本領(lǐng)，而且真正關(guān)心水手的健康。 not only...but also“不但……而且……”，連接并列主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞要和臨近的主語(yǔ)在人稱和數(shù)上保持一致；連接謂語(yǔ)動(dòng)詞時(shí)，not前不可有助動(dòng)詞；連接分句時(shí)，若not only位于句首，not only分句要用倒裝語(yǔ)序。 Not only you but also I am responsible for it. 不僅你而且我也有責(zé)任。 Not only was everything he had taken away from him，but also his citizenship.不僅他所有的一切都被帶走了，而且他的國(guó)籍也被沒(méi)收了。 　 　 ________ to help us, but he also wanted to lend us some money. A．Not only promised he B．Not only did he promise C．Not only he promised D．Not only he did promise 解析：選B　not only放在句子開(kāi)頭連接分句時(shí)，not only所在的分句需要用部分倒裝。 謂 語(yǔ) 動(dòng) 詞 謂語(yǔ)表述主語(yǔ)的行為動(dòng)作或所處的狀態(tài)。謂語(yǔ)的中心詞是限定動(dòng)詞，有人稱、數(shù)的變化。 1．及物動(dòng)詞、不及物動(dòng)詞和連系動(dòng)詞 (1)需要跟賓語(yǔ)的動(dòng)詞為及物動(dòng)詞。及物動(dòng)詞后面可以跟單賓語(yǔ)、雙賓語(yǔ)或者復(fù)合賓語(yǔ)(賓語(yǔ)＋賓語(yǔ)補(bǔ)足語(yǔ))。 ①單賓語(yǔ) He made the shortest speech Ive ever heard. 他做了我所聽(tīng)過(guò)的最短的演講。 ②雙賓語(yǔ) Mr.Schell wrote New York Times a letter the other day. 幾天前Schell 先生給《紐約時(shí)報(bào)》寫(xiě)了一封信。 ③賓語(yǔ)＋賓語(yǔ)補(bǔ)足語(yǔ)(常用于使役動(dòng)詞、感官動(dòng)詞、介詞with，without，like以及其他部分動(dòng)詞后面。) Have you found English difficult to speak? 你發(fā)現(xiàn)英語(yǔ)難說(shuō)嗎？ The big pine tree stood there like an umbrella covering the house. 聳立在那邊的那棵大松樹(shù)像一把雨傘遮住了房子。 (2)不需要跟賓語(yǔ)的動(dòng)詞是不及物動(dòng)詞。 Donald was lying on the bed.Donald躺在床上。 All the leaves have fallen and winter is ing. 所有的樹(shù)葉都落了，冬天就要到來(lái)了。 ①幾個(gè)不及物動(dòng)詞后加同源名詞時(shí)變成了及物動(dòng)詞 They are living a peaceful life.他們過(guò)著平靜的生活。 He died a heroic death.他死得很英勇。 The girl laughed a merry laugh.女孩愉快地笑了。 He sighed a deep sigh.他深嘆了一口氣。 ②許多動(dòng)詞往往既是不及物動(dòng)詞又是及物動(dòng)詞 (3)連系動(dòng)詞雖然本身具有一定意思，但不能獨(dú)立作謂語(yǔ)，需要帶有表語(yǔ)才能構(gòu)成謂語(yǔ)。 They have remained loyal to the government. 他們一直忠誠(chéng)于政府。 His body was the color of bronze. 他的身體呈青銅色。 2．短語(yǔ)動(dòng)詞 (1)動(dòng)詞＋副詞 Please put on your coat.請(qǐng)穿上大衣。 (2)動(dòng)詞＋介詞 The other day I came across a foreigner in the countryside.幾天前我在鄉(xiāng)下碰見(jiàn)了一個(gè)外國(guó)人。 (3)動(dòng)詞＋副詞＋介詞 Please keep up with others.請(qǐng)跟上其他人。 3．情態(tài)動(dòng)詞＋實(shí)義動(dòng)詞 You should not have done so.你不該那樣做。 4．主謂一致 英語(yǔ)句子中的主語(yǔ)和謂語(yǔ)應(yīng)在人稱和數(shù)上保持一致。這被稱作主謂一致。它主要遵循三個(gè)原則：意義一致原則、語(yǔ)法一致原則和鄰近原則。這三個(gè)原則常常發(fā)生矛盾，但當(dāng)發(fā)生沖突時(shí)，意義一致原則為優(yōu)先考慮的原則。 (1)語(yǔ)法一致原則 主語(yǔ)和謂語(yǔ)通常是從語(yǔ)法形式上取得一致，即主語(yǔ)是單數(shù)形式，謂語(yǔ)動(dòng)詞也采取單數(shù)形式；主語(yǔ)是復(fù)數(shù)形式，謂語(yǔ)動(dòng)詞也采取復(fù)數(shù)形式。 Mr.Black is a wellknown scientist on AIDS. 布萊克先生是著名的艾滋病科學(xué)家。 These books are intended for children under nine years old.這些書(shū)是專門(mén)為九歲以下的兒童設(shè)計(jì)的。 (2)意義一致原則 所謂意義一致原則是指謂語(yǔ)動(dòng)詞的變化是以主語(yǔ)所表達(dá)的單、復(fù)數(shù)概念而定。 Three months has passed since you left.(three months被看作一個(gè)時(shí)間整體，表示單數(shù)概念。)你已離開(kāi)三個(gè)月了。 The old are taken very good care of in our city.(the old指所有的老年人，指一類(lèi)人，表示復(fù)數(shù)概念。)在我們城市老年人被照顧得很好。 (3)鄰近一致原則 鄰近一致原則是指謂語(yǔ)動(dòng)詞的變化是以靠近謂語(yǔ)動(dòng)詞的主語(yǔ)部分而定。 Neither his parents nor he himself is a bank clerk.(根據(jù)靠近謂語(yǔ)的主語(yǔ)he而定。)他父母和他本人都不是銀行職員。 Not Jack but his parents are to blame for the home accident.(根據(jù)靠近謂語(yǔ)的主語(yǔ)his parents而定。)不是杰克而是他父母應(yīng)為這個(gè)家庭事故受到責(zé)備。 1．(天津高考)My parents always ________ great importance to my getting a good education.

A．were invited B．was invited C．have been invited D．has been invited 解析：選B　考查動(dòng)詞的時(shí)態(tài)和主謂一致。句意：那位著名的音樂(lè)家和他的學(xué)生被邀請(qǐng)?jiān)?012年臺(tái)北花博會(huì)的開(kāi)幕式上演出。首先，結(jié)合句意可知應(yīng)用一般過(guò)去時(shí)描述過(guò)去的行為；其次，as well as連接兩個(gè)并列主語(yǔ)時(shí)，謂語(yǔ)動(dòng)詞應(yīng)和前面的主語(yǔ)保持人稱和數(shù)的一致，本句謂語(yǔ)應(yīng)與the famous musician一致，用第三人稱單數(shù)形式，故選B。 6．(江蘇高考)Generally, students inner motivation with high expectations from others ________ essential to their development. A．is B．a(chǎn)re C．was D．were 解析：選A　考查主謂一致和時(shí)態(tài)。從題干可以看出本題的主語(yǔ)是students inner motivation，因此謂語(yǔ)動(dòng)詞用單數(shù)形式。根據(jù)題中的generally可知應(yīng)用一般現(xiàn)在時(shí)態(tài)。故選A。 Ⅰ.單項(xiàng)填空 1．(全國(guó)卷Ⅱ)Barbara is easy to recognize as shes the only one of the women who ________ evening dress.

A．remains B．is remained C．is remaining D．has been remained 解析：選A　考查動(dòng)詞。remain是不及物動(dòng)詞，故沒(méi)有被動(dòng)語(yǔ)態(tài)，排除B、D兩項(xiàng)，表示“存在”意義的狀態(tài)性動(dòng)詞一般不用于進(jìn)行時(shí)，所以此處用一般現(xiàn)在時(shí)。 3．(陜西高考)Ralph W．Emerson would always ________ new ideas that occurred to him. A．set off B．set about C．set up D．set down 解析：選D　考查動(dòng)詞短語(yǔ)辨析。句意：愛(ài)默生經(jīng)常寫(xiě)下他想到的那些新主意。根據(jù)句意，表示“寫(xiě)下，記下”，要用set down。set off“動(dòng)身”，set about“開(kāi)始做某事”，set up“建立”，均不符合句子的語(yǔ)境。故答案為D。 4．(江蘇高考)—Dad, I dont think Oliver the right sort of person for the job. —I see.Ill go right away and ________. A．pay him back B．pay him off C．put him away D．put him off 解析：選B　考查動(dòng)詞短語(yǔ)辨析。根據(jù)句意可知，Oliver 不能勝任這份工作，因此父親決定付清工錢(qián)打發(fā)他走，pay sb.off表示“付清工資解雇某人”。pay sb.back“報(bào)復(fù)”；put sb.away“把某人送進(jìn)監(jiān)獄或精神病院”；put sb.off“使某人分心”。 5．I called Hannah many times yesterday evening，but I couldnt get through.Her brother________on the phone all the time! A．was talking B．has been talking C．has talked D．talked 解析：選A　本題給出的時(shí)態(tài)依據(jù)應(yīng)該是yesterday evening，因此待填的時(shí)態(tài)就應(yīng)考慮過(guò)去時(shí)態(tài)，另外，此處表示talk的動(dòng)作是持續(xù)不斷的，所以應(yīng)用過(guò)去進(jìn)行時(shí)。 6．Young couples in China rushed to register their marriage on Jan 3rd, 2014, because the pronunciation of the number “201413” in Chinese ________ “l(fā)ove you all my life”． A．stands out B．stands for C．looks out D．looks for 解析：選B　句意：年輕男女在2014年1月3日涌入婚姻登記處，因?yàn)閿?shù)字201413的發(fā)音在漢語(yǔ)中代表“愛(ài)你一世一生”。stand out“突出；顯眼”；stand for“代表”；look out“往外看；注意”；look for“尋找”。 7．When he realized the police had spotted him，the man ________the exit as quickly as possible. A．made off B．made for C．made out D．made up 解析：選B　句意：當(dāng)他意識(shí)到警察認(rèn)出他時(shí)，他以最快的速度向出口走去。從the exit來(lái)判斷，是要表達(dá)向出口方向移動(dòng)，那么make for(走向)最為合適。make off“逃走”，但不能直接接the exit；make out“假裝，認(rèn)出”；make up“補(bǔ)充，虛構(gòu)”。 8．The water________cool when I jumped into the pool for morning exercise. A．was felt B．felt C．is felt D．feels 解析：選B　feel在此處是系動(dòng)詞，與其后的cool構(gòu)成系表結(jié)構(gòu)，不能用于被動(dòng)句。由從句可知應(yīng)用過(guò)去時(shí)。 9．—________Ted Greens new car? —No，when did you see it? —He________me a ride to the store yesterday.
