听力小贴士
听前对所需要填写的单词词性进行大胆猜测，通过文段主题及上下文情景，展开合理推测，预测考
数字用阿拉伯数字等。注意记数时采用国际习惯，每隔三位数用一逗号分开，即：1,000以上的数，先
从后向前数，每三位数加一"，"，第一个"号前为thousand,第二个"，"号前为million,第三
个"号前为billion;以billion,million和thousand为中心,听时集中注意力听清楚是多少个billion,
millionthousand,及时记下并在它们的后面分别用“，”分开，没有具体数字的就打上“0”。
1.听课本录音并模仿朗读。
2.熟记画线部分的词（组）和句子。

SpeakingandWriting
一、说的策略指导
一般来说，在句子中需重读的词都是实词：名词、动词、形容词、副词、数词等，一般关键词;不
重读的多为虚词：冠词、连词、介词、感叹词等。
二、写的策略指导
看图写作是根据给出的图画，写一篇英语短文。一般要求写记叙文，有时也要求夹叙夹议。整体上
可分为两个过程：一是弄清画面展示了什么情景;二是理解画面的内涵是什么。可以参照下列步骤：
1.读图：分析图画信息，发挥想象力，正确理解图画内容。
2.试写：结合图片中的情景，用自己熟悉的结构和词汇列出要点，忌用生疏的结构与词汇;将罗列
3.扩写：增加情节和过渡性词语，围绕图画和试写内容扩充、挖掘。
写作常用词汇：
表达过去行为的动词：常用过去时态。
