Question

2．Mr．Black's memory is getting____．As a result，he often leaves his keys at home．（　　）

• A． older
• B． poorer
• C． greater
• D． better

Answer 1

分析 布莱克先生的记忆力变差了．因此，他经常把钥匙落在家里．

解答 答案：B
根据"is getting_"可知，系动词"getting"后应该用形容词，又由"he often leaves his keys at home　他经常把钥匙落在家里"可知，布莱克先生的记忆力是变差了，暗含和以前比较之意所以用比较级．A　older　更老的；B　poorer　更差的；C　greater　更棒的；D　better　更好的．故答案为B

点评 做这道题要先根据句中现有词语确定应填词语的适当形式，然后选出正确的选项．
