由于好友反映很難找到美國英語教材《語境中的語法》這本書，講完昨天的練習，這個教材介紹就告一段落。

一、Be句型的作用練習

昨天留下的練習是這樣的：EXERCISE 2 Fill in the blanks to make true statements.

練習目的：理解Be句型的作用。

EXAMPLE: California is on the west (location位置) coast.

1. Washington, D.C., is on the east (location表位置) coast. （閱讀課文内容）

2. Chicago is a city (classification表分類). Illinois is a state. （閱讀課文内容）

3. Puerto Rico is an island (classification表分類) with water all around.

（課文中也有It is a territory的内容，但空格前給的是an，隻能填空元音音素開頭的island）

4. It is 20:00 p.m./20 o'clock (time表時間）now.

5. It is sunny (weather表天氣）today.

6. The American president is about seventy-three years old (age表年齡）.

7. The teacher is from Guang Dong, China (place of origin).

題目要求是make true statements，句子又是一般現在時，4-7題以今時今地真實情況内容作答。

重視初中基礎知識是高考卷2014年起引入短文改錯題型而面臨的新情況。

二、《新概念英語》Pre-Unit Test 1 Ex.D:

（一）D. Look at this example.看示例，懂要求。

She goes to town every day. -->She went to town yesterday.

将一般現在時的句子改為一般過去時，注意謂語時态變化和時間狀語變化規律。

（二）Do these in the same way. 用同樣方法改寫。

I. He buys a new car every year.

--> He ________ a new car last year.

2. She airs the room every day.

-->She ________ it this morning.

3. He often loses his pen.

-->He ________ his pen this morning.

4. He always listens to the news.

-->He ________ to the news yesterday.

5. She empties this basket every day.

-->She ________ it yesterday.

(三）參考答案：

1. bought 2.aired 3.lost 4. listened 5. emptied

溫馨提示：這個練習的基本功是不規則動詞過去式記憶和規則動詞加-ed詞尾變化的規則。
