题目内容
20．Breaking up large classes into several smaller ones （61）helps（help） students，but the improvements in many cases come whatever teachers do，a new research suggests．New （62）findings（finding） of the research from four nations，tell an interesting story．Small classes work for children，but that's （63）not because of how teachers teach，but because of what students feel they can do：get （64）more （much） face time with their teachers，for instance，or work in small groups with classmates．
"These are the same as what researchers have already known，"Gamoran says．There is no good evidence （65）thatteachers change their instructions based on changes in class size．Teachers are always strict with their students．Some teachers are making use （66）of small classes and others are not．There are a lot of differences．"It's not like that you reduce classes so teachers do something different and the achievement is higher，"he says．
In one study，researchers （67）closely（close） watched students'behaviours and found that students behaved better in smaller classes．They also （68）had（have） more direct communication with teachers and worked more in small groups rather by themselves．
One team，（69）led（lead） by Ronald Ehrenberg of Cornell University，finds that the potential benefits of class-size reduction"may be greater than what we observed"if only a few teachers change their teaching （70）to fit （fit） the smaller group．
分析 本文讲述了小班化教学的优点，以及实现小班化教学过程中会遇到的困难．
解答 61．helps 62．findings 63．not 64．more 65．that
66．of 67．closely 68．had 69．led 70．to fit
61．helps 考查动词第三人称单数形式．本句的主语是"Breaking up large classes into several smaller ones"这个短句，所以动词应该使用第三人称单数形式，故填"helps"．
62．findings 考查名词单复数形式．"finding发现"为可数名词，由于前面没有冠词，所以应该使用复数形式．故填"findings"．
63．not 考查固定搭配．根据下一句的"but"可知，这里填入"not"．not…but 不是…而是．故填"not"．
64．more 考查比较级．根据句意，小班教学可以让学生和老师见面的次数更多．故填"more"．
65．that 考查固定句型．根据固定句型 there is no…that，没有．可知，应补上"that"．故填"that"．
66．of 考查介词搭配．根据固定句型make use of 使用、利用．可知，应搭配介词"of"．故填"of"．
67．closely 考查副词．根据后面的动词"watched"可知，此处要用一个副词来修饰动词．故填"closely"．
68．had 考查动词．根据and后面的"worked more in small groups rather by themselves"中的动词"worked"可知，本句话使用一般过去时．故填"had"．
69．led 考查被动语态．根据后面的"by"可知，该处为省略be动词的被动语态．故填"led"．
70．to fit 考查不定式．根据句意可知，这里要填入不定式以表目的．句意：如果只有少数教师改变自己的教学方式以适应更小的班级．故填"to fit"．
