一、朗读下面的单词，在横线上写出每组单词中粗体部分的音标。
1. cloud cookie cabbage could

2. face city rice bicycle

3. duck luck pick sock

4. danger huge encourage passenger

5. relax excuse six box

1. /k/ 2. /s/ 3. /k/ 4. /dʒ/ 5. /ks/

1. 分析单词cloud, cookie, cabbage, could，粗体部分均为字母"c"，发音为/k/。
2. 分析单词face, city, rice, bicycle，粗体部分均为字母"c"（在i/e前），发音为/s/。
3. 分析单词duck, luck, pick, sock，粗体部分均为字母组合"ck"，发音为/k/。
4. 分析单词danger, huge, encourage, passenger，粗体部分均为字母"g"（在e/u前），发音为/dʒ/。
5. 分析单词relax, excuse, six, box，粗体部分均为字母"x"，发音为/ks/。

二、朗读下面方框中的单词，将粗体部分发音相同的单词正确归类。
helped called cleaned wanted
asked loved washed enjoyed
visited watched danced planted
needed finished started played
climbed painted

| /t/ |
| /d/ |
| /id/ |
通过上面的练习，我们可以发现以下规律：
1. 以清辅音结尾的单词加上 - ed 后，读。
2. 以浊辅音结尾的单词加上 - ed 后，读。
3. 以元音结尾的单词加上 - ed 后，读。
4. 以 /t/、/d/ 结尾的单词加上 - ed 后，读。

/t/: helped, asked, washed, watched, danced, finished
/d/: called, cleaned, loved, enjoyed, played, climbed
/id/: wanted, visited, planted, needed, started, painted
1. /t/
2. /d/
3. /d/
4. /ɪd/

先确定每个单词中-ed的发音。helped(/t/)、called(/d/)、cleaned(/d/)、wanted(/ɪd/)、asked(/t/)、loved(/d/)、washed(/t/)、enjoyed(/d/)、visited(/ɪd/)、watched(/t/)、danced(/t/)、planted(/ɪd/)、needed(/ɪd/)、finished(/t/)、started(/ɪd/)、played(/d/)、climbed(/d/)、painted(/ɪd/)。然后根据发音归类。规律部分根据发音规则填写。

三、根据汉语意思翻译下列句子，每空一词。
1. 我们参加学校旅行，去了废水处理厂。

2. 贝蒂过去常常和朋友们去剧院看演出。

3. 我认为得到干净的水并不容易。

4. 迈克去年对机器人感兴趣。

Germs are usually small .

1. school trip; wastewater plant
2. used to go; theater
3. it is easy to
4. was interested in
5. too; to see

1. "学校旅行"译为"school trip"，"废水处理厂"译为"wastewater plant"。
2. "过去常常做某事"用"used to do sth"，"剧院"译为"theater"。
3. "it is easy to do sth"表示"做某事容易"，否定前移后为"don't think it is easy to"。
4. "对……感兴趣"译为"be interested in"，last year提示用一般过去时，主语Mike为第三人称单数，be动词用was。
5. "太……而不能……"用"too...to..."，"看见"译为"see"。
