五、理解并运用
1. be动词的一般过去时：表示过去某一时间的状态，它常和表示过去的时间连用，如：yesterday昨天, last year去年, this morning今天早上等。was是am和is的过去式，were是are的过去式。它们的否定形式分别是wasn’t=was not, weren’t=were not。它们的一般疑问句是将was和were放到句首。例：I was born in Shanghai in 2001.我在2001年出生在上海。The frogs were black tadpoles.青蛙以前是黑色的蝌蚪。Were you in the library yesterday? No, I wasn’t. 你昨天在图书馆么？不，我不在。
2. like作动词时表示“喜欢”，作介词时表示“象，如；跟。。。一样”。注意区分：What does he like?他喜欢什么？What is he like?他是个什么样的人？（可指外貌或品行等）所以，What be 主语 like?的意思是“。。。怎么样？”相当于How be 主语？ 如：What is the weather like?天气怎么样？=____________What are the moths like?飞蛾长得怎么样？=____________What are the cats like?这些猫怎么样？=_______________
