　　题型突破栏目链接比较级与词形变换语法专题语法填空中，比较级和词形变换是常考点。解答这一题型，首先需分析句子的结构，明确空格在句中作何种成分并确定其词性，然后再作适当的词形转换。 1．当所给词为形容词或副词，或句中有than，a little，even，far等修饰或标志词时，用形容词或副词比较级。 ·It might have made it a little ________ (hard)for everybody because it meant they had to go by foot. (副词hard有a little修饰，故填比较级harder) 语法专题 2．作表语(系动词之后)，定语(修饰名词)或补语(表性质状态)时，通常用形容词形式。 ·That would be a very ________ (reason)thing to do in a big city，but it could destroy a small village like ours.(句中应作名词thing的定语，故填形容词reasonable) 3．作主语，或在及物动词、介词后作宾语时，通常用名词形式，前面可能有形容词修饰，注意单复数形式。 ·He had witnessed too many ________ (die)and wounds as the Battle of Solferino in Italy four years earlier.(指死亡，可数名词有too many修饰，所以填deaths) 语法专题 4．修饰动词、形容词、副词或整个句子，或作状语，用副词形式。 ·One hundred percent of all donations will go ________ (direct)to the charities.(用副词directly修饰go) 5．根据句子意思及前后逻辑关系，有可能考查与词根意义相反的源生词，此时需要在词根前加un－，im－，in－，ir－等，或在词根后加－less。 ·Also，the more children young couples have，the ________ (happy)they become.(“the＋比较级，the＋比较级”表示“越……越……”，根据语境“孩子越多，年轻夫妇就越不幸福”可知应填unhappier) 专项训练语法专题 Ⅰ.用括号中所给词的适当形式填空 1．We can have the most dedicated teachers，the most________(support) parents and the best schools in the world. 2．In a very real sense，each of us as human beings have been given an invisible golden box filled with________(condition) love and kisses from our children，family，friends and God. 语法专题
