托福阅读四：插入句子题

1、托福阅读：插入句子题解题技巧,考察能力,1、相关语句和词汇的理解 2、对于语段中的逻辑顺序的把握,题目特征,look at the four squares that indicate where the following sentence could be added to the passage. (you will see a sentence in bold) where would the sentence best fit? click on a to add the sentence to the passage.,question：,在托福阅读中，为什么不论插入题出现在文章的

2、那个位置，这种题都位于总结题之前,存在于倒数第二题的位置呢?,ets是一个很人性化的机构, 如果这类题出现在前几道题的位置, 选错了会对文章的理解造成影响, 影响做其它题。,插入的句子对文章本身的影响有多大？和几句话相关？如果和前后两句话都相关,是不是把它拿掉了, 就会对文章有较大的影响？,只需要找出待插入的句子跟前后某一句话的逻辑联系即可。,英语句子间的衔接手法(cohesivedevices),该题型重点考查英文句子间的逻辑语义关系，即英文中句子与句子是如何衔接在一起的。,cohesive devices,1.代词(pronouns)具体包括人称代词、指示代词和关系代词等（personal

3、, demonstrative, relative, etc）。 在上下句的关联中，代词是最为紧密的一类词。当作者再次谈及上句相关话题时，为了避免重复，遵循语言学的最简单化原理，作者会用代词指代该话题词。 例： speakingaforeignlanguageisanenormousassetinthemodernworld.thisiswhy somanyjuniorhighschoolsarenowofferinglanguageclasses. todaysteachersarefacedwithastarkchoice.theymustdecidewhethertoteach in a

4、waythathelpsstudentpassstandardizedexamsorteachinawaythatactuallyhelps studentslearn.,cohesive devices,2.定冠词the+名词(specificarticles+nouns)名词所指对象第一次出现时，用不定冠词a连接，当后句再次提及该名词对象时，为了表示它和前一句名词是同一关系，会用定冠词the引出。 例如：awomaniswalkingintoourclassroom.thewomanisourteacher.,cohesive devices,3.重复话题词或同义近义改写(repetiti

5、on,synonym,orslightvariationofaword) 上下句的衔接也可以通过重复话题词实现，或者是对该话题词进行相关改写。 例如: tofosterhealthyrelationshipsbetweenchildreninaclassroom,teachersshouldprovidetimeforgamesandfunactivities.havinghealthyrelationshipswiththeirpeershelpschildrengainconfidenceusefulinotherpartsoftheirlives.(重复话题词) beforechoosi

9、般是不对的。（因为代词不能跨句，如果在代词前面加一句话，就会改变代词的指代对象。但是有例外存在，比如一段中只有一个主语。） suggestion 3 优先考虑段落最后的空。（因为放在最末尾，对文章内容影响小。）,example 1:,extinct but already fully marine cetaceans are known from the fossil record. how was the gap between a walking mammal and a swimming whale bridged? missing until recently were fossils
