六、作文(1題)86.假設(shè)你的朋友叫楊立，是優(yōu)秀學(xué)生。校報(bào)請(qǐng)你寫一篇介紹他的短文。他的基本情況是：現(xiàn)在讀高二，是班長(zhǎng)，是全班學(xué)習(xí)最好的;最喜歡學(xué)習(xí)英語(yǔ)和數(shù)學(xué);愛好體育，課余常踢足球，還是學(xué)校游泳隊(duì)隊(duì)員;經(jīng)常幫助別人。注意：(1)基本情況不可遺漏;(2)要有標(biāo)題;(3)詞數(shù)為100左右。

參考答案

1.B

2.A本句考查兩個(gè)并列句之間的連接的詞。題干的意思是：“氣球能夠浮在空氣中正如船能夠浮在海面上一樣?！痹谒膫€(gè)選項(xiàng)中，只有A項(xiàng)的justas有“正如，猶如”的意思。故選A。

3.B解析：本題考查固定搭配。havetrouble(in)doingsth.“做某事有困難”。句意為：有時(shí)孩子們?cè)诜智骞适潞同F(xiàn)實(shí)方面會(huì)有困難，相信故事中的事確實(shí)存在。

4.D解析：forgetdoingsth．忘了已做過(guò)某事。注意區(qū)別forgettodosth。忘了而沒(méi)有做某事。

5.D本題考查時(shí)態(tài)。

【應(yīng)試指導(dǎo)】句意：當(dāng)你寫信回家的時(shí)候，請(qǐng)代我向你的妻子問(wèn)好。在時(shí)間狀語(yǔ)從句中用一般現(xiàn)在時(shí)代替一般將來(lái)時(shí)。

6.A解析：此題考查反意疑問(wèn)句的用法。主句為祈使句，因此其反意疑問(wèn)句用willyou。

7.C解析：句子的前半部分是主語(yǔ)從句，主語(yǔ)從句中的謂語(yǔ)動(dòng)詞時(shí)態(tài)應(yīng)根據(jù)句意而定。

8.B解析：此處是對(duì)將來(lái)情況的假設(shè)。虛擬條件句的謂語(yǔ)部分為should，had或were時(shí)，可把if省去，而把should，had或were放在從句的主語(yǔ)之前，構(gòu)成主謂部分倒裝。

9.D

10.A

11.C解析：副詞so置于句首，句子應(yīng)該用倒裝語(yǔ)序，某人受傷用sb.beinjured來(lái)表示，故答案為C。

12.B解析：本題考查動(dòng)詞固定搭配的用法。deprive后常接介詞of，表示剝奪什么。

13.D

14.Blaunch為“發(fā)射”講；其余為干擾項(xiàng)。

15.B

16.C

17.C解析：本題考查詞義的辨別。rise出現(xiàn)，put放下，raise提起，arise升高。

18.B解析：本題考查固定搭配的用法。當(dāng)否定詞位于句前時(shí)，得出結(jié)論應(yīng)用reach/achievein/arriveatconclusion，故選B。

19.Bsetout意為“出發(fā)，動(dòng)身”。

20.B解析：takemeasures意思為“采取措施”，本句應(yīng)用被動(dòng)語(yǔ)態(tài)。

21.A

22.D

23.C

24.C解析：much用在句中修飾比較級(jí)better。

25.D解析：which修飾非限定性定語(yǔ)從句，指代前邊一句話。本題涉及句法知識(shí)——簡(jiǎn)單句、并列句和復(fù)合句。例如：Hehastwodaughters.Theyaredoctors.(簡(jiǎn)單句)Hehastwodaughtersandtheyaredoctors.(并列句)Hehastwodaughters,whoaredoctors．(復(fù)合句)

26.D

27.D

28.B

29.B解析：encourage：鼓勵(lì)、鼓舞；discourage：使泄氣；prevent：阻止；ask：要求。根據(jù)句意只有選B。

30.D

31.C解析：本題考查倒裝虛擬語(yǔ)氣用法。本句是表示與將來(lái)事實(shí)相反，所以從句用wereto形式。句意為：如果他今天出發(fā)的話，他就會(huì)在星期五以前到達(dá)那里。

32.B

33.C

34.A

35.D

36.D

37.B

38.B

39.D解析：本題考查動(dòng)詞搭配。doone'shomework“做作業(yè)”；makemistakes“犯錯(cuò)誤”。句意為：做作業(yè)，還要保證別犯錯(cuò)誤。

40.A

41.B解析：theeducationsystem是主語(yǔ)，謂語(yǔ)動(dòng)詞應(yīng)用單數(shù)；thedesiredresults意為“期望的結(jié)果”。

42.A解析：反問(wèn)疑問(wèn)句的陳述部分是肯定式時(shí)，疑問(wèn)部分用否定式。以letme或letus起始的反問(wèn)疑問(wèn)句，疑問(wèn)部分用willyou或won'tyou，所以選項(xiàng)A是正確的。

43.C

44.C所有的學(xué)生都去看了昨天的魔術(shù)表演。它太令人不可思議了。這里主要考查的是動(dòng)詞的現(xiàn)在分詞和過(guò)去分詞的不同用法。Sth．bedoing表示某一事物令人怎么樣。Sb．bedone表示某人處于某種狀態(tài)。例：Theletteristouching．這封信令人感動(dòng)。

Iammoved．我很感動(dòng)。

45.A解析：while意為“雖然”；as意為“因?yàn)椤?；if意為“如果”；since意為“因?yàn)椤?。根?jù)題意選A。

46.C

47.A解析：本題考虛擬語(yǔ)氣在名詞性從句中的用法。在“ask(advise，desire，ordersuggest，require，etc。)+the廣引導(dǎo)的從句中，謂語(yǔ)動(dòng)詞應(yīng)用“should+認(rèn)”，should可以省去，再結(jié)合語(yǔ)態(tài)，故A項(xiàng)正確。本句大意為：他們要求所有的必要文件都必須在月底之前交到校長(zhǎng)辦公室。

48.B解析：cuts“裁減”；shortages“短缺”；weaknesses“弱點(diǎn)”；imports“進(jìn)口”，故正確選項(xiàng)為B。

49.D解析：上句責(zé)備瑪麗應(yīng)該做作業(yè)而不是坐到那兒看電視，下句是瑪麗對(duì)媽媽責(zé)備的一種辯解：“你說(shuō)過(guò)電視是有教育意義的。”所以D項(xiàng)正確。

50.A解析：句意：她昏倒了。給她臉上澆些水，或許她會(huì)醒過(guò)來(lái)。本題考查詞組辨析。comeround：過(guò)訪，繞道而來(lái)，蘇醒過(guò)來(lái)；comeback：回來(lái)，恢復(fù)；comeagain：再說(shuō)一遍，重復(fù)一遍；comeout：出來(lái)，傳出。

51.對(duì)青少年來(lái)說(shuō)，要逆世俗潮流，走自己的路，是越來(lái)越難了。
