eg.Ourcountryisbecomingmoreandmorebeautiful.6.the+比较级+从句，the+比较级+从句“越……，越……”eg.Theharderyoustudy,thebettergradesyouget.四、最高级用法（表示三者或三者以上(人或事物)的比较,其中有一个在某一方面超过其他几个时,用最高级）。1.最高级的前面一般要加定冠词the,2.主语+谓语+最高级+of/among+类别的词语主语+谓语+最高级+in+范围的词语

eg.Heisthetallestoftheboysinourclass.3.much，byfar，the+序数词,修饰最高级

eg.HuangheisthesecondlongestriverinChina.4.oneof+the+最高级+名词复数“最……之一”

eg.Parisisoneofthebiggestcitiesintheworld.5.选择疑问句，A，BorC？一、忌不同类事物进行比较。

他的电脑比我的便宜。误：HiscomputerischeaperthanI.正：Hiscomputerischeaperthanmine.析：在比较级的句子中，相比较的双方必须是同类事物，否则会造成歧义。这里mine=mycomputer。比较级使用禁忌误：ThepopulationofChinaislargerthanIndia.正：ThepopulationofChinaislargerthanthat(=thepopulation)ofIndia.中国的人口比印度的人口多。误：ThestudentsofClassTwostudyharderthanClassOne.正：ThestudentsofClassTwostudyharderthanthoseofClassOne.

二班的学生比一班的学生读书用功。误：InwinteritiscolderinBeijingthanShanghai.正：Inwinter,itiscolderinBeijingthaninShanghai.冬天北京比上海冷。

二、忌自己与自己进行比较。1.比尔比他班上的其他男孩都高。误：Billistallerthananyboyinhisclass.正：Billistallerthananyotherboyinhisclass.正：Billistallerthantheotherboysinhisclass.析：在比较级的句子中，同一类人或物在同一范围内进行比较，要把自己排除在比较范围之外。2.玛丽歌唱得比班里的任何一个男孩都好。误：Marysingsbetterthananyotherboyinherclass.正：Marysingsbetterthananyboyinherclass.析：在比较级的句子中，主语和范围之外的人或事进行比较时用"any+单数名词"。又如：ShanghaiislargerthananycityinJapan.（上海比日本的任何一个城市都要大。）但是：ShanghaiislargerthananyothercityinChina.（上海比中国任何一个其他城市都大。）三、忌错用修饰词。吉姆比他妹妹大得多。误：Jimisveryolderthanhissister.正：Jimismucholderthanhissister.析：比较级前面常用much,alittle,far,even（更），alot,still（更）等副词来修饰，表示程度，不可用very,too,quite等词来修饰。四、忌错用表示范围的介词。李玲在我们班年龄最小。误：LiLingistheyoungestofourclass.正：LiLingistheyoungestinourclass.析：表示范围的短语有1）in+one's/the+n.在…里2）of+the+数词+名词复数在几个…中3）of+all+the+名词复数在所有的…中如：Tomwritesbestofthethreeboys.在这三个男孩中，汤姆写字最好。

五、忌错用主格宾格。下面两句话中，than后面一句用I，一句用me,两者都可以。HeistallerthanI.他比我长得高。

Heistallerthanme.(多用于口语中)但是有些句子中，用主格和宾格时意义不同。例如：

Iliketheboybetterthanher.我喜欢那个男孩胜于喜欢她。

Iliketheboybetterthanshe.我比她更喜欢那个男孩。

MrSmithlikeshisfriendbetterthanhiswife.史密斯先生比他的妻子更喜欢他的朋友。(也可理解为：史密斯先生喜欢他的朋友胜过喜欢自己的妻子)如果把省略的部分写出来，便可避免歧义：

MrSmithlikeshisfriendbetterthanhelikeshiswife.

史密斯先生喜欢他的朋友胜过喜欢自己的妻子。六、几种句型的转换同一个意思往往可以用不同的句型来表达。例如：

JackistallerthanJill.杰克比吉尔长得高。

=JillisshorterthanJack.吉尔长得比杰克矮。

JillislesstallthanJack.

=JillisnotastallasJack.吉尔长得不如杰克高。

Thisbookislessinterestingthanthatone.=Thisbookisnotasinterestingasthatone.

这本书不如那本有趣。
