3.以重读闭音节结尾的动词，末尾只有一个辅音字母时，双写最后一个字母，再加ing

解析:本题考查现在进行时在情景问答中的运用。由第1题的“Look at”“He is watering the flowers.”以及第2题的“he isn't reading books”可知，第1、2题的时态都是现在进行时。根据第1题的答句可推测出问句应用特殊疑问句；第2题用“no”回答，故问句应用一般疑问句。

1. Tom always ______ black shoes,but today he ____ white shoes.
A. to wear,is wearing
B. wears,wearing
C. wears,is wearing

变疑问 be 提前，否定 not 再 后添；
何时要用进行时 look，listen，now标志。
