【翻譯】這本詞典很有用,但它比舊的那一本貴兩倍。
[考點(diǎn)]倍數(shù)表達(dá)法
【精析】A 常用的倍數(shù)表達(dá)方式有:①A+謂語(yǔ)+倍數(shù)+形容詞或副詞的比較級(jí)+than+B;②A+謂語(yǔ)+倍數(shù)+as+形容詞或副詞的原級(jí)+as+B;③A+謂語(yǔ)+倍數(shù)+the size/length/height/width…+of+B,表示“A是B大/長(zhǎng)/高/寬……的X倍(A比B大、長(zhǎng)、高、寬等X-1倍)”。expensive的比較級(jí)是more expensive,A項(xiàng)符合第一種結(jié)構(gòu)。故選A。
2.If I a student now, I would study hard and listen to my parents' advice.
A.was
B.were
C.had been
D.would be
【翻譯】如果我現(xiàn)在是個(gè)學(xué)生的話,我會(huì)努力學(xué)習(xí),并聽(tīng)從父母的建議。
[考點(diǎn)]虛擬語(yǔ)氣
【精析】B 分析句子結(jié)構(gòu)可知,本句包含一個(gè)If引導(dǎo)的非真實(shí)條件句。根據(jù)從句中的時(shí)間狀語(yǔ)now和主句中的would study…and listen可知,本句是對(duì)現(xiàn)在情況的假設(shè),所以從句的謂語(yǔ)動(dòng)詞應(yīng)用過(guò)去式(be動(dòng)詞用were)。故選B。
3.There a duck and several geese swimming in the river.
A.be
B.have
C.is
D.are
【翻譯】河里有一只鴨子和幾只鵝在游泳。
[考點(diǎn)]主謂一致
【精析】C 在There be句型中,謂語(yǔ)動(dòng)詞的單復(fù)數(shù)應(yīng)遵循“就近原則”,即謂語(yǔ)動(dòng)詞的單復(fù)數(shù)形式取決于最靠近它的主語(yǔ)(主要指名詞或代詞),所以此處謂語(yǔ)動(dòng)詞的數(shù)應(yīng)與a duck保持一致,用單數(shù)形式。故選C。
4. You had better them in advance if you can't make it.
A.to inform
B.inform
C.informing
D.informed
【翻譯】如果你不能出席,你最好提前通知他們。
[考點(diǎn)]非謂語(yǔ)動(dòng)詞
【精析】B had better do sth.為固定用法,意為“(告訴別人應(yīng)該做的事)應(yīng)該做某事,最好做某事”,其中better后是省略to的不定式結(jié)構(gòu)。故選B。常考的后接省略to的不定式結(jié)構(gòu)有:①在固定短語(yǔ)had better, would rather, may/might (just) as well, cannot help but等之后;②在do nothing but, have nothing to do but等句型中,后接省略to的不定式,但若but前面不是實(shí)義動(dòng)詞do的某種形式,則不定式不省略to;③why not常用來(lái)表示建議、命令、贊成、詢問(wèn)等,其后要用省略to的不定式,意為“為什么不……”,相當(dāng)于why don't you…。
5. If I the train this morning, I would arrive in an hour.
A.would catch
B.caught
C.had caught
D.would have caught
【翻譯】如果我今天早上趕上了火車,一個(gè)小時(shí)后我就到了。
[考點(diǎn)]虛擬語(yǔ)氣
【精析】C 根據(jù)主句中的時(shí)間狀語(yǔ)in an hour(一個(gè)小時(shí)后)和從句中的時(shí)間狀語(yǔ)this morning(今天早上)可知,本題考查的是錯(cuò)綜時(shí)間條件句,主句是對(duì)將來(lái)情況的假設(shè),從句是對(duì)過(guò)去情況的假設(shè),所以主句的謂語(yǔ)動(dòng)詞應(yīng)用“should/would/could/might+動(dòng)詞原形”的形式,從句的謂語(yǔ)動(dòng)詞應(yīng)用“had+過(guò)去分詞”的形式。故選C。
