(两者中)后者的many support the former view，but i favour the latter (one)很多人都支持前一种看法，但我赞成后一种。2)辨析latter和later：the latter half of his essay contains penetrating observations.他的论文后半部分有深入的论述。he was charged with

last指代最后一样事物，不能用latter。later指时间的先后而言，表示“较后的”“较新的”，它能作形容词，也能作副词。单项填空television has many advantages.it keeps us _ of the _ news and also provides entertainment in the house.ainformed；latestbto

this weekend.现在未来学是很大的生意，许多人将参加研讨会，他们梦想在这个周末听到的预测的基础上开始新事业。剖析：本句是and连接的复合并列句。they will hear this weekend是定语从句，修饰the predictions；based on是过去分词短语作后置定语，相当于which are based on.。the tv show was based on real life.那部电视剧是根据现实生活写成的。考点：注意短语dream of的用法。against all the odds she achieved her dream of becoming a ballerina.她克服重重困难，实现了当芭蕾舞演员的梦想。when he was a kid，he dreamed of becoming a

carry out the plan.她使这项计划的实施成为可能。we consider it a waste of time to go on with the project.我们认为继续搞这项工程是浪费时间。our teacher believes it necessary that we master english.老师认为我们有必要掌握英语。归纳：在“find，make，consider，think等动词宾语宾语补足语”结构中，若宾语为动名词、不定式或从句，则通常使用形式宾语it，而真正的宾语放在宾语补足语之后。1) your smile is one of the strongest tools that make _ possible for you to meet new
