27、 kind of pollution. it s 15d fothangs in the world.書面表達。人類只有一個地球。根據(jù)提示,以“ saving the earth”為題,寫一篇 80詞左右的短文。 提示:1.如何保護環(huán)境已成為世界最大難題之一;2 .各種污染破壞環(huán)境,損害健康;3 .不要亂倒垃圾,亂排廢水;4 .我們應(yīng)該保護環(huán)境,使我們的家園更加美麗。saving the earthhow to protect the environment has become one of the biggest problems in the world. there are many
28、kinds of pollutions around us, such as air pollution, noise pollution, water pollution and light pollution. we can find that rubbish not only pollutes our environment but also harms people health. so we should not throw rubbish everywhere. some factories pour waste water into the rivers and the lake
29、s. the behavior of these factories will pollute the water, and sometimes it can kill the fish living in them.we have only one earth. we must keep our environment clean and tidy. we must try our best to protect her, and make our home more beautiful.答案i. 1.a 根據(jù)答語判斷,本題考查帶有“for+一段時間”的完成時態(tài)。2.d 現(xiàn)在完成時表示從過去
30、某一時刻延續(xù)到現(xiàn)在的一段時間,往往用for, since短語來表示。for+一段時間,since+過去時間點或從句,所以卞據(jù)ten years ago選才d d項。3.b much too 后接形容詞、 副詞 ; too many 后接可數(shù)名詞復(fù)數(shù) ; too much 后接不可數(shù)名詞 , pollution 是一個不可數(shù)名詞,故選 b 。4.d 本題考查at least和no+adj.(比較級)+than,表達的含義是“至少它不比你買給我的 (花)差。 ”5.b stand作及物動詞,意為“忍耐,容忍”后接名詞、代詞或動名詞作賓語。6.c 本題考查 make sb. do sth. 這一結(jié)構(gòu)
31、。7.b 動詞(組)作主語,應(yīng)用其動名詞 -ing 形式。8.b 本題主要考查yet在現(xiàn)在完成時態(tài)中的運用,yet用于否定句和疑問句中, already用于肯定句中。9.b there be+sth./sb. doing sth.為固定句型,意為“有某人或某物正在”。10.a see+賓語+doing ,表示“看到某動作正在進行“。.11.where have you been?12 .how did you go there?13 .have you ever been there before?14 .whom did you travel with?15 .how long have y
32、ou been away?id.16.a see看,throw扔,drop丟,clean弄干凈,根據(jù)題意此處選a。17 .d 本句的題意: 我能在三分鐘內(nèi)走到那兒。 in three minutes 表示 3 分鐘內(nèi),故選d 。18 .c 本題考查sothat句型,表示“如此以至于”。本句題意:但是有一天,這兒有那么多的垃圾,讓我很不高興。故選 c 。19 .b 本題考查系動詞+ 形容詞。根據(jù)題意可知: feel happy 感到高興。20 .a 本句分析句子結(jié)構(gòu),有一個介詞短語 after i started to pick up litter 修飾 ten minutes 來作時間的定語,
33、指“撿了十分鐘的垃圾后” 。所以選 a 。21 .c 由 four times a year 一年四次,表示頻度,可看出此處時態(tài)用一般現(xiàn)在時。22 .d 從全文來看,作者為了保護環(huán)境而去撿垃圾,這件事不是讓“我”感到累、難過、有趣,而是一種責(zé)任和成就感。所以此處選擇 d 項。23 .c any 在此處表示“任一” ,本句含義是“如果垃圾中有任何能夠回收再利用的,我都把它留下來” 。 a 、 b 兩項均修飾可數(shù)名詞,而litter 是不可數(shù)名詞, d 項不符合題意。24 .a until后跟短暫性動詞,表示“直到才”,從題意來看只有 a項符合。25 .b 根據(jù)題意“我只是做了一點事去幫助地球” 。此處是用不定式短語
