Ⅱ. 写出单词:根据句意及首字母写出单词
2. —Emma sings

than Ella. —Yes，and she also sings better.
3. —Who do you think is more
hard-working

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：根据“sings better”及首字母l，可知是“唱得更大声”，loud的比较级是louder，故填louder。
3. hard-working
解析：根据“gets better grades”及首字母h，可知是“更勤奋”，hard-working意为“勤奋的”，故填hard-working。
4. lazy
解析：根据“Go and wash your teeth!”可知，不要做“懒惰的”男孩，lazy意为“懒惰的”，故填lazy。
5. shyer
解析：根据“She doesn't want to attend group activities”及首字母s，可知是“更害羞”，shy的比较级是shyer，故填shyer。
Ⅲ.完成句子:用单词的适当形式填空
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：两个空后都有“than”（比），这是比较级的标志词，所以都要用形容词或副词的比较级形式。“good”的比较级是“better”；“loud”的比较级是“louder”。
2. **performed**
- 解析：句中的“last week”（上周）是一般过去时的时间标志词，所以动词要用过去式，“perform”的过去式是“performed”。
3. **solving**
- 解析：“give up doing sth.”是固定搭配，意为“放弃做某事”，所以这里用“solve”的动名词形式“solving”。
★★★句型转换:按要求完成句子
1. Chen Jie plays more carefully than Peter. (用 as...as 改写)
Peter ____ ____ ____ ____ Chen Jie.
2. I work as hard as my sister. (用比较级否定改写)
My sister ____ ____ ____ ____ me.
3. Tom finishes homework faster than Linda. (改为一般疑问句)
____ Tom ____ ____ ____ than Linda?
4. Peter runs more slowly than Chen Jie. (转换主语)
Chen Jie ____ ____ ____ Peter.
5. This book is not as interesting as that one. (用比较级改写)
That book is ____ ____ than this book.
答案：解答
1. **doesn't play as carefully as**
- 解析：“as...as”结构表示“和……一样”，中间用形容词或副词原级。原句是陈洁比彼得演奏得更仔细，改写后要表达彼得演奏得不如陈洁仔细，主语“Peter”是第三人称单数，一般现在时的否定句借助助动词“doesn't”，后面动词用原形“play”，“carefully”用原级。
2. **doesn't work harder than**
- 解析：原句是“我和我姐姐工作一样努力”，用比较级否定改写，要表达“我姐姐工作不比我努力”，主语“My sister”是第三人称单数，一般现在时的否定句借助助动词“doesn't”，后面动词用原形“work”，“hard”用比较级。
3. **Does; finish homework faster**
- 解析：一般现在时的句子，主语“Tom”是第三人称单数，改为一般疑问句要借助助动词“Does”，放在句首，后面动词“finishes”变回原形“finish”。
4. **runs faster than**
- 解析：原句是“彼得比陈洁跑得更慢”，转换主语后要表达“陈洁比彼得跑得更快”，“faster than”表示“比……更快”。
5. **more interesting**
- 解析：原句是“这本书不如那本书有趣”，用比较级改写就是“那本书比这本书更有趣”，“interesting”的比较级是“more interesting”。

outgoing
(outgoing) as Peter，but she plays the Chinese 2. ______
flute
(flute) much better. When Peter 3. ______

(perform) together.
答案：1. outgoing
解析：“as+形容词原级+as”，outgoing是形容词原级，故填outgoing。
2. flute
解析：“Chinese flute”意为“中国 flute”，flute用单数，故填flute。
3. encourages
解析：主语Peter是第三人称单数，时态是一般现在时，encourage的第三人称单数是encourages，故填encourages。
4. singing
解析：“be afraid of doing sth.”是固定搭配，sing的动名词是singing，故填singing。
5. to perform
解析：“decide to do sth.”是固定搭配，意为“决定做某事”，故填to perform。
