Ⅱ. 寫出單詞:根據(jù)句意及首字母寫出單詞
2. —Emma sings
louder
than Ella. —Yes，and she also sings better.
3. —Who do you think is more
hard-working
? —Peter，I think. Because he always gets better grades.
4. Go and wash your teeth! Don't be a
lazy
boy.
5. Lucy is
shyer
than Chen Jie. She doesn't want to attend group activities.
答案：2. louder
解析：根據(jù)“sings better”及首字母l，可知是“唱得更大聲”，loud的比較級是louder，故填louder。
3. hard-working
解析：根據(jù)“gets better grades”及首字母h，可知是“更勤奮”，hard-working意為“勤奮的”，故填hard-working。
4. lazy
解析：根據(jù)“Go and wash your teeth!”可知，不要做“懶惰的”男孩，lazy意為“懶惰的”，故填lazy。
5. shyer
解析：根據(jù)“She doesn't want to attend group activities”及首字母s，可知是“更害羞”，shy的比較級是shyer，故填shyer。
Ⅲ.完成句子:用單詞的適當形式填空
1. Chen Jie plays the Chinese flute ____ (good) than Peter, but Peter sings ____ (loud) than her.
2. Chen Jie was nervous, but she ____ (perform) beautifully at the festival last week.
3. Teachers told us, "Never give up ____ (solve) the problem".
答案： 解答
1. **better**；**louder**
- 解析：兩個空后都有“than”（比），這是比較級的標志詞，所以都要用形容詞或副詞的比較級形式。“good”的比較級是“better”；“l(fā)oud”的比較級是“l(fā)ouder”。
2. **performed**
- 解析：句中的“l(fā)ast week”（上周）是一般過去時的時間標志詞，所以動詞要用過去式，“perform”的過去式是“performed”。
3. **solving**
- 解析：“give up doing sth.”是固定搭配，意為“放棄做某事”，所以這里用“solve”的動名詞形式“solving”。
★★★句型轉換:按要求完成句子
1. Chen Jie plays more carefully than Peter. (用 as...as 改寫)
Peter ____ ____ ____ ____ Chen Jie.
2. I work as hard as my sister. (用比較級否定改寫)
My sister ____ ____ ____ ____ me.
3. Tom finishes homework faster than Linda. (改為一般疑問句)
____ Tom ____ ____ ____ than Linda?
4. Peter runs more slowly than Chen Jie. (轉換主語)
Chen Jie ____ ____ ____ Peter.
5. This book is not as interesting as that one. (用比較級改寫)
That book is ____ ____ than this book.
答案：解答
1. **doesn't play as carefully as**
- 解析：“as...as”結構表示“和……一樣”，中間用形容詞或副詞原級。原句是陳潔比彼得演奏得更仔細，改寫后要表達彼得演奏得不如陳潔仔細，主語“Peter”是第三人稱單數(shù)，一般現(xiàn)在時的否定句借助助動詞“doesn't”，后面動詞用原形“play”，“carefully”用原級。
2. **doesn't work harder than**
- 解析：原句是“我和我姐姐工作一樣努力”，用比較級否定改寫，要表達“我姐姐工作不比我努力”，主語“My sister”是第三人稱單數(shù)，一般現(xiàn)在時的否定句借助助動詞“doesn't”，后面動詞用原形“work”，“hard”用比較級。
3. **Does; finish homework faster**
- 解析：一般現(xiàn)在時的句子，主語“Tom”是第三人稱單數(shù)，改為一般疑問句要借助助動詞“Does”，放在句首，后面動詞“finishes”變回原形“finish”。
4. **runs faster than**
- 解析：原句是“彼得比陳潔跑得更慢”，轉換主語后要表達“陳潔比彼得跑得更快”，“faster than”表示“比……更快”。
5. **more interesting**
- 解析：原句是“這本書不如那本書有趣”，用比較級改寫就是“那本書比這本書更有趣”，“interesting”的比較級是“more interesting”。
根據(jù)短文內容用單詞的適當形式填空
Chen Jie and Peter are members of the school music club. Chen Jie is not as 1.
outgoing
(outgoing) as Peter，but she plays the Chinese 2. ______
flute
(flute) much better. When Peter 3. ______
encourages
(encourage) her to perform at the festival，she feels nervous because she is afraid of 4. ______
singing
(sing) alone. Finally，they decide 5. ______
to perform
(perform) together.
答案：1. outgoing
解析：“as+形容詞原級+as”，outgoing是形容詞原級，故填outgoing。
2. flute
解析：“Chinese flute”意為“中國 flute”，flute用單數(shù)，故填flute。
3. encourages
解析：主語Peter是第三人稱單數(shù)，時態(tài)是一般現(xiàn)在時，encourage的第三人稱單數(shù)是encourages，故填encourages。
4. singing
解析：“be afraid of doing sth.”是固定搭配，sing的動名詞是singing，故填singing。
5. to perform
解析：“decide to do sth.”是固定搭配，意為“決定做某事”，故填to perform。
