教学建议

本单元重点例句及相关知识的讲解

1. Come to school in your old clothes tomorrow.

明天请穿旧衣服来学校。

英语中表示“穿”的词有wear, put on, have on, dress, be in, etc. 它们的具体用法如下：

wear, have on和be in强调状态，wear有时可用进行时态；put on强调动作；dress既可表示状态，也可表示动作, dress后不直接跟表示服装、鞋、帽等名词，而其他所列名词后跟服装鞋帽等名词，be in后可接表示颜色的名词。例如：

Lucy is too young to dress herself. Tom was putting on his trousers when Lucy called him. Tom pushed the door and asked, “Do you know Kate?” Lucy answered, “I’ve know the girl in red before. ” Kate was in a red coat when she came in. She helped Lucy to dress. Everything is ready now. Lucy is wearing a new hat. Tom has on a black coat.

2. The ground must be just right——neither too wet nor too dry.

土壤一定要正好，既不能太湿，也不能太干。

【范文】Knowledge

Knowledge is to us what a compass is to a ship. A ship has to rely on a compass to sail safely across an unknown ocean. Similarly, knowledge brings forth power we need to make real progress toward a better life. With knowledge, we can invent new and useful apparatus and machines; we can create beautiful art, including paintings, sculpture, music, and so forth; we can make clothes, furniture, cars, space shuttles and the like. It is knowledge that enables us humans to lead a convenient and colorful life. On the contrary, were it not for knowledge, people would become stupid and uncivilized; everything would get back to the primitive age; no more human history could be passed down. In short, the more knowledge we gain, the wiser we will become.

That is, knowledge is indispensable to mankind. (138 words)
