B．mustgetC．shouldhavegot D．shouldget答案：A本題考查情態(tài)動詞。句意：孩子們一定是在樹林里迷路了，否則按時間他們會在湖邊野營了。根據(jù)下文可知此處是做了很有把握的肯定的推測，故用must；由wouldhavebeen可知是過去的事情，要表示對于過去的事情的推測要用“情態(tài)動詞＋havedone”的形式，故選A項。C項表示“本應(yīng)該做某事(而沒做)”。(3)IgotcloseenoughtohearthemspeakingChinese,andIsaid“NiHao”，justasI________doinChina.A.mustB.mightC.canD.should答案：B本題考查情態(tài)動詞。must“必須，一定”；might表示推測，“可能，或許”，常用于肯定句和否定句；can表示推測時常用于否定句和疑問句，“可能”；should表示“(按照義務(wù)、責任)應(yīng)該，應(yīng)當”。句意：我靠得足夠近聽到他們在說漢語，我也像在中國我可能做的那樣，說了一聲“您好”。根據(jù)句意應(yīng)選B項。2．Theymaybemanykilometreslongwithplasticballstokeepthemfloatingonthewater,andweightstoholdthemdownontheseabed.他們或許有數(shù)千米長，且?guī)в兴芰锨颍宰屗鼈兤≡谒嫔?；它們也帶有很多重物，以讓它們沉到海床上?1)該句是一個簡單句。句中and連接的兩個介語短語withplasticballs...和(with)weights...作狀語，以說明主語的狀況；不定式短語tokeep...和tohold...作后置定語。(2)句中使用了“keep＋賓語＋賓補”結(jié)構(gòu)，keep意為“使……處于某種狀態(tài)”。該結(jié)構(gòu)的常見形式有：①keep＋sb./sth.＋形容詞/副詞Iwastootiredtokeepmyeyesopen.我累得眼睛都睜不開了。Inourdailylife,wemustkeepourselvesawayfromdanger.日常生活中，我們必須使自己遠離危險。②keep＋sb./sth.＋介賓短語Youshouldkeepyourhandsbehindyourbacks.你們要把手放在背后。③keep＋sb./sth.＋現(xiàn)在分詞(表示動詞或狀態(tài)的持續(xù))I'msorry.Ihavekeptyouwaitingoutsideforsolong.對不起，我讓你在外面等了那么久。④keep＋sb./sth.＋過去分詞(表示被動和狀態(tài)的持續(xù))Keepyourmouthshutandyoureyesopen.少說話，多觀察。活學活用(1)補全句子他媽媽讓他在外面站了五分鐘。Hismotherkept________________________for5minutes.答案：himstandingoutside(2)Lucyhasagreatsenseofhumorandalwayskeepshercolleagues________withherstories.A．a(chǎn)mused
