1、一、重點詞匯講解1. public 公共的，公共場所, sign 標記 ，public sign公共場所標牌 ，復數形式:public signs。2. years old 歲 例如：four years old 四歲；ten years old 十歲。注意：years要用復數形式，但one year old除外3. always 一直，總是，頻率副詞，小學課本中類似的詞還有：usually 通常，sometimes 有時，often經常等，常與一般現在時連用。 4. ask questions 提問題；answer questions 回答問題。 5. mean 表示，意味 mean dif

2、ferent things 表示不同的意思6. stay away from 遠離keep off 不接近。 7. shouldnt=should not 8. the birds cage 鳥籠，birds為復數名詞的所有格。 9. make noise 大聲喧嘩；其反義詞組：be quiet, keep quiet 10. No smoking. 禁止吸煙；No littering. 禁止亂扔垃圾；No parking. 禁止停車；No eating or drinking. 禁止在此用餐。No后面的動詞用動名詞的形式，動名詞由動詞原形加ing構成：smoke-smoking； litte

3、r-littering； park-parking； eat-eating； drink-drinking 11. Do not touch. 請勿觸摸。do 后面的動詞用原形。 12. take a walk 去散步 13. look around 環顧四周 14. pick up 把.撿起來， pick it up，pick them up 15. come up 來到 16. point to 指著 二、重點句型講解1What does this/that sign mean? It means 這個、那個標志表示什么意思，它表示2Can I ? No, you cant. You sh

4、ould now. 我能嗎？不，你不能。你現在應該三、語法講解 1情態動詞：在英文中主要用來表示說話人的看法，態度等，有以下特點：本身都有一定意義； 不能單獨作謂語；在句中不受任何人稱，數的變化的影響，目前我們學過的這些情態動詞后跟的動詞一般都是動詞原形：can (否定 cannot=cant) 能，may (否定 may not) 可以，must 必須 (語氣強于should) (must not=mustnt 絕不能，不可以)，should 應該，義務 ( 否定 should not=shouldnt)2一般現在時在一般現在時中，行為動詞與he, she, it等第三人稱單數的搭配時須在行

5、為動詞后加s或es，如:It means Danger.將句子變為一般疑問句時要借助于助動詞does來幫忙，此時行為動詞要用動詞原形，如：Does this sign mean “No smoking”?第三人稱單數的特殊疑問句是在一般疑問句的基礎上，再于句首加上特殊疑問詞， 如： What does this/that sign mean?聽力材料及答案一、根據所聽內容，選出你所聽到的單詞或詞組1 Theres no sign on the grass.2 I can see a lot of flowers in the garden.3 Jack, please pick up the
