timethecentralgovernment_____someeffectivemeasurestobringthemundercontrol.A.haveincreased;wouldtake

B.haveincreased;willtakeC.havebeenincreasing;takes

D.havebeenincreasing;took参考答案：D【详解】考查时态。句意：自从去年年底房价一直在上涨。因此，该是中央政府采取措施降低并控制房价的时候了。由since判断句中需要完成时，并且根据语境，房价还在上涨中，故第一空用完成进行时；第二空考查句型"It's/wastimethat该是…的时候了"，从句中往往用过去时，也可以用"should+动词原形"；故答案是D。【点睛】1.Since自从---以来（可做介词和连词），和现在完成时态连用。Hehaslivedheresincehecame.自从他来到这里，就一直在这里住着。2.Itisthefirst(second---)timethat主语+现在完成时态+其他。意思是：第几次做某事了。如果把is改成was，则后面用过去完成时态。It’sthethirdtimethatIhavecometotheSummerPalace.这是我第三次来到颐和园。3.It’s(high)timethat主语+一般过去时态+其他。现在是该做某事的时间了。It’shightimethatwehadlunch.现在是我们该吃午饭的时间了。4.Itis/hasbeen+一段时间+since主语+一般过去时态+---。自从---有多长时间了。在这个句型中since引导时间状语从句，从句用一般过去时态，分两种情况：（1）如果从句的动词是终止性动词leave/come/---，则表示“从动作开始到现在多长时间了。”Itisthreeyearssincehebegantosmoke.他已经吸烟三年了。（2）如果从句的动词是持续性动词stay/smoke/live---，则表示“从动作结束到现在多长时间了”。Itisthreeyearssincehesmoked.他戒烟三年了。13.Hemissed___goldinthehighjump,butwillget___secondchanceinthelongjump.A.the;the

B.不填;a

C.the;a

D.a;不填参考答案：C14.——Ihearyourauntlikestravel,music,clothesandfinefood.

——Oh,yeah,andmusicmayhavebeen____ofhertastes.

A.therathermorerespectable

B.muchthemostrespectable

C.verythemostrespectable

D.evenmorerespectableone参考答案：B

本题考查形容词的比较级和最高级。第一句中的“travel，music，clothesandfinefood”已给出提示，此空格处要用最高级，所以我们首先排除A和D项。very和much都可以修饰最高级，但在句中的位置不同。very在定冠词the之后，而much则在the之前。15.Grandmadoesallherownshoppingandcooking—Ihaveneverseen____agedperson.A.anindependent B.amoreindependentC.themostindependent D.themoreindependent参考答案：B试题分析：句意：奶奶自己购物做饭，我从没见过比她更独立的老年人。否定词加比较级表示最高级意思，a修饰person。根据句意选B.二、书面表达16.基础写作(共1小题,满分15分)以下是你校最近一次主题活动的主要内容：主题：如何做一名受欢迎的学生对象：全体高三学生时间：上星期三下午地点：学校图书馆程序：实例分析→小组讨论→老师点评结论：行为端正；学习认真；为人着想；讲礼貌；与人融洽相处影响：认识了自我,决心做个受欢迎的学生
