22、主句经常用现在完成时，也可用一般现在时。但since引导的从句要用一般过去时。1This is the third time that I have visited the Great Wall.这已经是我第三次来长城了。2It has been/is about 2 years since I came to Nankai University.我来到南开大学已有两年了。3It has been/is a long time since I last came to the town.自从我上次到城里已有很长时间了。答案.1.former2.supporting3.enthusiastic4
23、.mystery5.treasure6.observed7.lately/recently8.exists.1.take off2.separated from3.picked up4.dreamed of5.so far6.began with7.carry out8.Take care.1.(1)divided into(2)separate；from(3)separate；from解析separate.from.把从中分开，强调把原来连在一起，靠近或相似的分隔开来。divide.into.把分成，强调把整体分成若干份。2(1)latest(2)late(3)later(4)lately(
24、5)latter(6)later解析late adj./adv.“迟的，晚的”，通常表示时间上的晚或迟；lately adv.“最近，近来”，相当于recently，多与现在完成时连用；later adv.后来，以后；latter adj.常与定冠词the连用，表示列举两者中的后者，与the former相对；latest adj.最新的，最近的。3(1)provide(2)supply(3)offered(4)supplied解析supply意为“供给，供应”，“为某人提供某物”通常用作supply sb. with sth.或supply sth. to sb.，不能使用supply st
25、h. for sb.。provide意为“提供，供应，备办”，“为某人提供某物”常用作provide sb. with sth.或provide sth. for sb.。offer意为“(主动)提供，提出”，表示“为某人提供某物”，通常后面接双宾语，构成offer sb. sth.或offer sth. to sb.。4(1)too much(2)much too(3)too much解析(1)too much可以修饰不可数名词，在句子中作定语；too much也可以单独使用，相当于一个代词，在句子中可以作表语或者宾语；too much还可以作副词，在句中作状语，表示“过于”“太多”(mor
26、e than enough)。(2)much too用法同too，只用作副词，不单独使用，后面要接形容词或其他副词。虽然too much和much too都可用作副词，但too much不可以修饰形容词，而much too不可以修饰动词。.1.has；read2.has been reading3.have not been；enjoyed4.has been discovered5.has；been sent6.have been travelling7.have；swum8.have；been playing.1.A句意为：没有事实，我们就不能形成有价值的观点，因为我们的思考必须以真实的知
27、识为基础。upon which to base our thinking 是动词不定式短语作定语，该短语中介词必须放在which前，故选A。2A句意为：医院里的每个人都希望他会在几天治疗之后恢复健康。pick up恢复健康；take up从事；占据；give up放弃；make up编造；弥补；化妆；和解。3B句意为：直到最近我才了解到她这些天感到不舒服的原因。lately最近，同recently。4D本题为短语辨析题。A、B两项搭配错误；C项中offer为及物动词，后接双宾语，因此应去掉介词with。句意为：设备改进后，人造卫星开始向科学家提供整个地球的气象图。5D由句中“for month
28、s”与“will”可知，prepare的动作应发生在过去而且到目前还在继续，故用现在完成进行时。6C根据从句whether it will remain so用一般将来时态可以判断出，价格的下调对现在产生了影响，故用现在完成时态，故选C。7Bhe was used to为定语从句，修饰先行词country life，而其宾语为省去的关系代词that/which，又根据时间状语since 1992，可知B项正确。8C句意为：对不起，玛西娅，一位来自Vanity Fair的记者一整天都在打电话，你现在能和她通话吗？表示过去开始的动作一直持续进行到现在，用现在完成进行时态。题干中all day表示一
29、段时间。9A根据句意，既然glad to see you back，说明stay in Russia这一动作已发生，且发生在过去，未涉及现在的状况，所以C、D两项不合适；B项是过去进行时，指过去某时正在发生的动作，所以也不正确；A项是一般过去时，用来陈述过去时间内发生的动作，故选A。10C时间状语so far表示“到目前为止”，它常和现在完成时连用，故选C。 11.B句意为：当你到家时，给我打电话，让我知道你已经安全到达了。根据句意应选B项have arrived。are arriving为现在进行时表将来；had arrived为过去完成时，强调动作的发生时间为过去的过去；will arri
30、ve为一般将来时，三者均不符合句意。12D句意为：哎呀，杰克，你看上去很疲倦！噢，我一直在粉刷房子，明天必须完工。由句意可知paint这一动作一直延续到tomorrow，故用现在完成进行时。13D句意为：每年大量农民工涌入深圳，去寻找他们离乡前别人给他们许诺的挣钱的工作。此处农民工是“被许诺工作”，需用被动语态，故排除A和C两项；B项仅表一般过去时的被动；D项表示“已经被许诺”，故选D。14A句意为：我不得不去看医生，因为我最近一直咳嗽得很厉害。由时间状语lately和句子语境可以得出，这里用现在完成进行时最合适，表示最近一段时间以来一直在进行的动作，暗含此动作有可能还继续进行下去。15D句意
31、为：对不起，我没有听清楚你的话。你是说你们想在9月20日返回吗？对不起，我自己没有说清楚。我们想在10月20日返回。根据句意可知“我”虽然刚刚已经表达了自己的意思，但现在导致的结果是没有表达清楚，所以应用现在完成时，故选D。.1.C文章第一句便点题“在全世界可以使用的水的总量一直是人们感兴趣的”，故引起下文“拥有泉水或溪流有时意味着控制”，故选C项。use使用；hold抓住，一般用于掌握权力；担任职务；find发现。2A因为下文提到like the desert所以此处为dry areas；deserted “荒芜的”，荒芜、废弃的地方不一定缺水。3Crich land意为“富饶肥沃的土地”，
32、本句暗示出“人们控制水要比拥有富饶肥沃的土地还重要”。4Duncommon意为“不寻常的”，本句中not uncommon即为common，说明为争水而引起争斗打仗是常事，可见水是重要的。5Amake laws to do制订法律做。6Bsettlers意为“外来殖民者”。7Das作为关系代词引导非限制性定语从句。8B由上文可知水并不是像人们想的那样用之不尽，取之不竭的，因此“there is not enough water.”。9Cthe amount of.的数量/总量。10Brequire需要，根据上下文可知用水需要有计划地节约使用。11A根据上下文可知应选effectively，意为“有效地”。12Daccording to为介词短语，意为“根据”。13Acorrect water supply forecast中的correct意为“正确的”或“准确的”。14D该空与下文below相对使用，故填above。15Brising表示增加，此空需填不及物动词。16Cmountain tops山顶上。rock岩石；tip尖端；tree树，均不合题意。17Bmake use of为固定词组，意为“使用，利用”。18Dgathered意为“收集到的”，过去分词作定语。19Cpress a button按开关。20C用情态动词will更含有一种趋势，可能性更大。
