[高考复习指南] (通用版)2017届高考英语一轮语法填空和短文改错专题复习课件:第5讲 形容词和副词

[复制链接]

  (4)比较等级常见错误:①修饰词出现错误:more不可修饰比较级,但可以用much来加强比较级,意为“……得多,更……”。②使用比较级时比较的对象要一致:相同的对象可以比较,不同的对象不能进行比较。③在语法填空和短文改错中对比较级的考查更倾向于从“语句的深层意义”中体会出来而不是从“结构”中看出来,因此在解题时需要跟进语境判断题干中是否暗含比较含义,并且仔细判断是两者之间还是两者以上的比较。如: ♦ Its too noisy here.Can we go somewhere quieter? 这里太吵闹了。我们能不能去个安静点儿的地方? ♦ His first book is of great use for our course. But his latest one is better worth reading.他的第一本书对我们学习课程很有用,但他最新的那本更值得一读。 3.倍数句型。 (1)A is+倍数+比较级+thanB (2)A is+倍数+as+原级+asB (3)A is+倍数+the+名词(sizelengthheight等)+ofB (4)A is+倍数+that/those ofB (5)A is+倍数+what引导的名词性从句 ♦ It is reported that the United States consumes four times as much energy as the whole of Africa.据报道,美国消耗的能源是整个非洲的四倍。 ♦ The geography teacher tells us that China has almost the same size as the USA but its population is six times as large as/the size of that of the USA.地理老师告诉我们,中国在面积上与美国几乎一样大,但是人口却是美国的六倍。 ♦ The output of this year is three times that of 2015.=The output of this year is three times what it was in 2015.今年的产量是2015年的三倍。 [即时训练] Ⅰ.单句语法填空 1.It may not be a great suggestion.But before a ____________(good)one is put forwardwell make do with it. 解析:句意:它或许不是一个好建议,但在有更好的建议之前,我们先凑合一下。此处暗含比较,表示“一条更好的建议”。 better 2.(2016·安徽江南十校联考改编)—I watched the film you mentioned. —Isnt it cool? —Absolutely.It cant be much ____________(good). 解析:句意:——我看你提及的那部电影了。——你不觉得很棒吗?——绝对是,没有比这更好的了。本题考查“否定词+比较级”表示最高级。也可根据设空处前有much修饰可知,应用形容词的比较级形式。 better 3.Tom does very well in computer study and much to my joyJane does no ____________ (bad) than Tom. 解析:句意:汤姆的计算机学得很好,使我高兴的是,简做得和他一样好。“no+比较级+than”是固定搭配,意为“和……一样不”。本句中有no,所以填worse成为双重否定,意为“和……一样好”。 worse Ⅱ.单句改错 1.Its said that the power plant is now twice much large as what it was. ____________________________________________________ 解析:本题考查倍数表达法。 句意:据说这个发电厂现在是以前的两倍大。根据倍数表达法:A is+倍数+比较级+thanBA is+倍数+as+原级+asB。所以本题需将much改为asmuchas 2.Some think online shopping was more convenient and the goods are cheap. ____________________________________________________ 解析:句意:有些人认为网购更方便,商品更便宜。根据前面的“more convenient”可知此处应用比较级形式。 cheapcheaper 形容词和副词的词形变化及词性转换是形容词和副词的考查热点。如果用来修饰名词或在系动词后作表语,应用形容词形式;如果用来修饰形容词、副词、动词或整个句子,则应用副词形式。正确分析句子结构,判断设空处在句中所作的句子成分,并牢记转换形容词和副词的规则及构词法,是解答此类题目的关键。 形容词和副词的词性转换 1.常见的形容词后缀。 (1)­able: reasonablecomfortableenjoyablesuitableadjustable; (2)­al: naturaladditionaleducationaltraditionalnational; (3)­antent: significantimportantexcellentdifferentconvenient; (4)­ishfoolishselfishchildish; (5)­iveactiveimpressivedecisiveattractiveeffectiveinstructive; (6)­lymanlyscholarlyfriendlylivelydeadly; (7)­fulbeautifulwonderfulhelpfulusefulsuccessfulmeaningfulthankfulpowerful; (8)­ousdangerousgenerouscourageousvarious; (9)­lessendlessaimlesspowerless; (10)­ysunnywindyfunnycloudyrainyhealthywealthy; (11)­dedunitedorganizedclosedwoundeddevelopedappreciatedusedcrowdedpollutedworriedmarriedterrifiedsatisfied; (12)­ingdevelopinglivingsleeping. 2.形容词转换为副词的变化规则。 情况 变化规则 例词 一般情况 以y结尾的形容词 辅音字母+e结尾的形容词 在词尾加­ly kindkindly
