1. First, ... then, ... next, ... finally, ...首先，……然后，……接著，……最后，……這是英語中表達做某事的步驟的一種說法。如果步驟較多，還可以說：first-next-after that-later on-finally/at last通常你會聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時，他們會做一些停頓。這樣就能提前告訴聽者接下來講的是一系列的步驟。這一點在朗讀和聽力中應特別注意。2. how many, how much均為疑問詞，同是“多少”，但用法不同。請看：how many修飾可數(shù)名詞復數(shù)，how much修飾不可數(shù)名詞。但在用法上，同學們常犯如下錯誤：1) [誤] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many，much是形容詞，常修飾名詞作定語，故后面跟名詞。2) [誤]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修飾不可數(shù)名詞時，謂語動詞用單數(shù)。how many與how much的區(qū)別可簡記為：前how many：問“多少”，復數(shù)名詞后面跑；how much問“多少”，不可數(shù)名詞單數(shù)好。前者答語用基數(shù)詞，后者答語用數(shù)量關(guān)系。

二、新授環(huán)節(jié)新授環(huán)節(jié)是本堂課的重點，我主要分為6步來突破語言點，步步為營，環(huán)環(huán)相扣，達到既定目標。1、首先我用touch and guess游戲來呈現(xiàn)新授單詞present，通過CAI展示各種生日禮物，如衣服，書本，玩具等讓學生操練單詞：Books can be a present等，操練時做到詞不離句。2、接著我借助多媒體讓學生說說自己想要的禮物I want a_____，同時我將實現(xiàn)準備的實物和圖片作為禮物贈送給他們，新授句子Here’s a present for you，激發(fā)學生開口說的興趣，又為接下來的操練提供了資源。我利用剛才分發(fā)的禮物采用游戲 “I’m a little bee”， （S1：I’m a little bee. Today is my birthday. S3：Here’a present for you。）四人小組合作操練這個句型。既避免了操練的機械性又調(diào)動了學生的積極性，而且提供了讓每個學生開口說的機會，關(guān)注學生個體的發(fā)展。3、當學生Act完后，我對一學生說：Oh, little bee, what’s your present? Open it and see。讓學生打開禮物呈現(xiàn)實物生日賀卡教學詞匯birthday card。既做到了呈現(xiàn)自然，又滲透西方文化知識，培養(yǎng)學生跨文化交際意識。

What are they? 對學生所掌握的知識進行滾動復習，同時又為新課做鋪墊。（二）新知呈現(xiàn)為了更好地突出教學重點，分散難點，在這一環(huán)節(jié)將利用多媒體設置不同的任務來完成新知呈現(xiàn)。1、任務一：四季的色彩和景色課件展示春夏秋冬四季的圖片。問學生：What colour is the spring/summer/fall/ winter?在學生回答后再向?qū)W生提問：What’s your favourite season? Why?請學生根據(jù)四季的“顏色”來選擇自己喜歡的季節(jié)，引導學生用句型“Because I see…”來說出自己喜歡的理由。通過“I see…”這個角度，培養(yǎng)學生善于觀察大自然，熱愛大自然的情感。2、任務二：四季的天氣和著裝提問學生“What’s the weather like in spring/summer/fall/winter?”讓學生通過談論“天氣和著裝”來選擇自己喜歡的季節(jié)，并能從生活實際出發(fā)，利用句型“Because I wear…”陳述喜歡的理由，進一步培養(yǎng)學生的思維能力。
