2020版高考新创新一轮复习英语北师大版学案：语法第一部分第三讲形容词、副词

第三讲形容词、副词 形容词与副词的比较等级　 [全析考法]Ⅰ.单句语法填空1．(2018·全国卷Ⅰ)According to a review of evidence in a medical journal, runners live three years ________ (long) than non­runners.解析：longer　根据空后的than和语境可知，此处应该使用副词比较级形式，故填longer。 2．(2018·全国卷Ⅲ)He screams the ________ (loud) of all.解析：loudest　根据空前的the以及空后的of all可知此处应用副词最高级。3．(2018·6月浙江高考)There could be an even ________ (high) cost on your health.解析：higher　此处表示这么做可能还会让你付出更高的健康代价。根据even可判断，此处要用形容词的比较级。4．(2017·全国卷Ⅰ)As a result, people will eat more food to try to make up for that something missing.Even ________ (bad), the amount of fast food that people eat goes up.解析：worse　根据语境可知，此处表示程度的加深，所以用副词比较级形式，even worse表示“更糟糕的是”。5．(2017·6月浙江高考)Sixteen years ________ (early), Pahlsson had removed the diamond ring to cook a meal.解析：earlier　sixteen years earlier表示“早在16年前”。此时的earlier相当于before，一般直接跟在时间名词的后面。6．(2016·全国卷Ⅱ)If you feel stressed by responsibilities at work, you should take a step back and identify (识别) those of ________ (great) and less importance.解析：greater　and连接并列成分，根据后面的less可知，此处要用形容词比较级形式。7．(2014·全国卷Ⅰ)Finally, that hard work paid off and now the water in the river is ________ (clean) than ever.解析：cleaner　从后面的“than”可知此处要用形容词比较级，故填cleaner。8．(2014·广东高考)After our plane landed, we went to the hotel.We had made our reservation six months ________ (early), but the man at the front desk said there had been a mistake.解析：earlier　由“had made”可知该动作发生在到达旅馆之前，故应该是早在六个月之前我们就已经预订了，所以用副词比较级earlier。Ⅱ.单句改错1．(2018·全国卷Ⅲ)I was afraid to speak in front of a larger group of people.________________解析：larger→large　根据句意，作者害怕在一大群人面前讲话，这里没有比较的含义，故将larger改为large。2．(2017·全国卷Ⅱ)They often get up earlier and water the vegetables together.________________解析：earlier→early　get up early意为“早起”，句中没有比较的意思，故不用比较级。3．(2016·四川高考)The dishes that I cooked were Mom's favoritest.________________解析：favoritest→favorite　favorite没有比较级和最高级。 [谨记规则] (一)形容词和副词比较等级的构成规则1．规则变化 构成例词原级比较级最高级单音节的词一般情况下直接加­er和­estsmallsmallersmallestgreatgreatergreatesthardharderhardest以不发音的e结尾的单音节词加­r和­stnicenicernicestcutecutercutestlargelargerlargest以一个辅音字母结尾，且前面只有一个元音的词，先双写词尾的辅音字母后再加­er和­estfatfatterfattestthinthinnerthinnesthothotterhottest以“辅音字母＋y”结尾的词，先把y变为i再加­er和­esteasyeasiereasiesthappyhappierhappiestearlyearlierearliest其他双音节和多音节的形容词或副词都在前面加more和mostcarefulmore
