在第一阶段的单元复习时,学生务必加强词汇、短语的记忆。对考纲词汇,不仅要记住词义、词性,还要掌握其主要用法和搭配。另外,学生还要注意旧词新意。在复习过程中,要善于对有共同用法或特点的词汇进行归纳,形成相关的小知识网络。1.同一动词的不同搭配搭配活跃的常用动词有如下几个:break,bring,call,come,cut,die,do,get,give,go,have,keep,look,make,put,set,take,turn等,复习时将这些动词与不同的介词和副词的搭配罗列在一起进行记忆。如die的常用搭配:diedown渐渐减弱;die out消灭,灭绝;die away逐渐消逝;die 相似文献

<正>After a long winter, the arrival of spring can be a welcome relief. The days grow longer, the temperatures increase, and the natural world around us comes to life again. But when the seasons change, our sleep patterns change with them.New research suggests that humans may need more sleep in the winter than they do in the summer. A German study found that participants slept an hour longer in December than in June, regardless of their exposure to light. “Our study shows that even while li... 相似文献
