1. For Mary, the keys to becoming a healthy eater involved finding nutrition habits that worked with her lifestyle and _________ (have) the support of a health coach.
問題:由and 可知,have和worked應(yīng)為并列并系,應(yīng)填had,但是為什么答案卻是having呢?(學(xué)生 陳震達(dá))
此空應(yīng)該是和involved并列,答案應(yīng)該是had, 為什么不對?(學(xué)生 黃慧青)
解答:and 是并列連詞,這對我們做題是一個很好的提示,但是我們要學(xué)會恰當(dāng)分析句子成分,準(zhǔn)確找出and前后對應(yīng)的成分。本句的謂語動詞是involved,而finding the nutrition habits that worked with her lifestyle 和 ______ (have) the support of a health coach是兩個并列的賓語,與(have)并列的是finding,而不是worked或involved,故填having。本句句意為:對瑪麗來說,成為一個健康飲食者的關(guān)鍵包括找到對她的生活方式奏效的營養(yǎng)習(xí)慣及得到健康指導(dǎo)教練的支持。
2. Everyone in our class was hard-working and did what we could _______(enter) a good college.
問題:情態(tài)動詞后應(yīng)當(dāng)用動詞原形,答案為什么不是enter?(學(xué)生 溫寶明)
解答:我們可以從以下幾個例子逐層對句子進(jìn)行分析:We should do something to enter a good college. 從這句我們可以看出: to enter作目的狀語;進(jìn)一步:We should do something that we can (do) to enter a good college. 當(dāng)主句里出現(xiàn)了實(shí)意動詞do的某種形式后,從句的do可以省略,同樣to enter 作目的狀語;再進(jìn)一步:因something that 相當(dāng)于引導(dǎo)名詞性從句的what,用what來替換something that,那么句子就變成了:We should do what we can to enter a good college. 本題的情況跟此句一樣,what we could 是did的賓語,這個賓語從句中的情態(tài)動詞could后省略了動詞原形do,(enter)a good college是目的狀語,故填to enter。
3. We can hardly imagine the difficulty the graduates have__________ (hunt) for a job.
問題:have后面應(yīng)該用to do, 為什么用doing?(學(xué)生 盧稱新)
解答:分析句子成分,可知the graduates have是省略了關(guān)系代詞that或which的定語從句,修飾先行詞the difficulty,所以have的賓語應(yīng)該是代表the difficulty的that或which,因此,此句考查的是have difficulty (in) doing something(做某事有困難)這一固定句式,故填hunting。
4. Limited natural resources should be made full use of ________ (meet) the increasing need of energy.
問題:介詞后面應(yīng)該用動名詞,可答案為什么不是meeting呢? (學(xué)生 何健華)
解答:在做題的時候一定要分析句子成分,不能斷章取義,一看到熟悉的形式就不動腦筋了。我們把這句話變成主動句:We should make full use of limited natural resources ______ (meet) the increasing need of energy. 句中make use of 可以用同義詞use來代替,這樣,句子就變成:We should use limited natural resources ______(meet)the increasing need of energy. 結(jié)合我們學(xué)過的搭配use something to do something,可知此句用to meet作目的狀語。將此句變成被動句,返回到開頭的那個題目,可見meet在句子中作目的狀語,答案應(yīng)為to meet。
5. I felt so excited the first time I had it, as I was about _____ (tell) people around the world, “I have been to China and now I am eating real Chinese food!” (學(xué)生 鐘家麗)
問題:about是介詞,介詞后面應(yīng)該用動名詞,為什么用to tell?
解答:這道題做錯,就是受到了慣性思維的干擾,一看到about就判斷出介詞后面用動名詞,這是不對的。做題時要認(rèn)真分析,本題考查的是be about to do something (正要做某事或打算做某事),故填to tell。
