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.1.fortable4.uncertain 5judgement6.changed7.heard8.asked9.frightened；frightened；frightening10.Lost.1.dont；seem；to；care2.is；made；up；of3.Not；all 4though/as；they；are5.If；it；is6.that/which；was；mentioned7.on；my；part；not；on8.the；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；occupation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。.1.B本题考查倒装句。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。2C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Given more 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。10C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，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
