19、间副词引导的完全倒装句：以地点副词 here，there 等和时间副词 now，then等开头，后面的动词是 be，come，exist，fall，follow，go，lie，remain，seem，stand 等，并且句子的主语是名词，就可以用完全倒装。2表方位的介词短语置于句首，并且句子的主语是名词，可以用完全倒装。(1)Here comes the bus.公共汽车来了。(2)Between Li Li and Li Lei sits Mary.玛丽坐在李莉和李磊中间。答案.5judgement；frightened；frightening.1.dont；seem；to；care；mad

20、e；up；of；all4though/as；they；are；it；iswhich；was；mentioned；my；part；not；on；other.1.(1)attentive(2)cautious(3)careful(4)cautious解析attentive 留神的；注意的，含有聚精会神的意思；careful 小心的；仔细的，只是消极地要求避免错误；cautious 当心的；谨慎的，主要是防避危险。2(1)occupation(2)job(3)trade(4)profession(5)career(6)profession解析job 指用以谋生的工作，尤指为他人所雇；occupati

21、on 表示某人所从事的职业，是更正式的用语(如填表格信息的字样)；profession 指需要专业教育和训练的职业，如医生和律师等；trade 指需要特殊手工技巧的职业、手艺；career 指希望终生从事的职业、事业、生涯。3(1)contains(2)involves(3)includes(4)involve解析contain 包含以作为整体的全部(需列举所有事物)；include 包含以作为整体的部分(不需要列举所有事物)；involve 必须包含某种结果，牵涉，包含。include 和 contain 都指具体的物质的实体和它们的各部分；involve 侧重于非实体的事物及要素。.本题考

22、查倒装句。表方位的介词短语置于句首，并且句子的主语是名词时，要用完全倒装。2 C句意为：这封信写得那么乱以至于我不能理解作者是想表达什么意思。work out算出；结果是；有满意的结果；turn out 结果是；使外翻；关(煤气、灯等)；倒空；生产；figure out 想出；理解；计算出；count out 清点人(物)数目；不算在内。3D根据句中的 have been 可知 new events 已经加入到比赛中，表示完成的动作；而且 add 与 events 又存在被动关系，答案为 D。4A根据语境，我们应选 A，因为 things 与 lose 的关系是 lose things，是动宾

23、关系，things 是被丢的。5C根据题意可知，the Olympic Games 与 play 之间是被动关系，因此可以排除 A和 D，另外 B 表示将来的动作，也应排除，故答案为 C。它可还原成一个非限制性定语从句：which was first played in 776 BC。6A句子主语 the trees 与 give 之间是被动关系，故答案选 A，过去分词短语 Givenmore attention 作条件状语，放于句首。7Adrive 与句子主语 farmers 的关系是 farmers 被驱使，因此用 driven 表示被动关系。8Donce begun 在句中作条件状语，它

24、是状语从句 once it is begun 的省略形式，句意为：这项调查研究事先计划得如此完好，以致于一旦开始，什么也无法改变它。9B完整的说法应是 when the drug is taken according to the directions.由于主句的主语和从句的主语相同，因此可以省略从句的主语 the drug 和谓语的一部分 is，答案为 B。当然也可以省去 when。10 C过去分词paid作系动词get的表语，类似的用法还有：get married，get beaten，get excited，get caught in 等。11A本题的选项处含有“leave宾语宾补”结构

25、，分词和不定式都可作该结构的补语；但据题意此处应为“使某人感到不满意的”，故应用过去分词形式的形容词 unsatisfied作补语。12B本题考查形容词短语在句中作状语的用法。surprising“令人惊奇的”，多用来描述一件事或某个物品的性质；surprised“感到惊奇的，”多用来描述人的心理状态；故 A、D 两项可排除；C 项从语义上讲多用来指正在发生的动作，从语法上讲多在句中作原因状语，与此时情景不符，故 B 项正确，为形容词短语作伴随状语。13Ccompleted in the 1880s 为过去分词短语作定语修饰 the Town Hall，二者之间为被动关系且动作已完成；A 项表

26、示动作将要发生；D 项表示动作正在发生，均不合题意；B 项不能作限制性的定语。14A“with宾语宾补”结构中，当宾补表示被动与完成时，用过去分词。15 C_at the back of the classroom 为分词短语作定语。sit 为不及物动词，可用 sitting.作定语；seat 为及物动词，常与反身代词连用或用 be seated 形式。这里 seat与 those 构成逻辑上的动宾关系，故用其过去分词作定语。.“我提出领他去目的地”，offer to do sth.意为“(主动)提出做某事”。从后文“hecoldly refused my offer”也可得此答案。2D“我”

27、提出要帮他，但他冷冷地拒绝了，这出乎“我”的意料，因此用 to mysurprise。3D他担心“我”会向他要钱。4D从前文我们得知此空填 helped。5Afall deep in thought 意为“陷入沉思”。6AD 项有一定干扰性，从后文“.money is becoming more and more important in oursociety.”知作者承认钱是重要的，因此 D 项不合题意。7C因为问题并非出在钱本身，因此钱与好坏无关。8B本段是对第二段的总结。钱本身与好坏无关，问题在于我们对钱的态度。9C句意为：目前，我们的物质生活比以前更丰富了。A 项有一定干扰性，powe

28、rful意思是“力量大的”，因此不合题意。10Abut 一词对此空的选择起了重要作用。句意为：物质生活丰富了，然而人们却越来越冷漠了。11Akey 在这里的意思是“关键”。12D句意为：关键是人们价值观的改变。personal values 个人价值观。13D他们错误地认为赚钱是他们一生中唯一的目标。14Athink up 在这里的意思是“想出”。15A句意为：他们想尽各种办法来实现这个目标。this aim 指赚钱的目标。16C从空后的 fooled 得此答案。17B其他答案均有一定干扰性。通过上下文我们可以看出，作者在此由个人推及整个社会，因此 B 项为最佳答案。18B前后句之间为转折关系。19D整个文章讲人们对钱的追求。20Dwholeheartedly 意为“全心全意地”。
