当堂达标（见导学案“当堂达标”）
答案与解析：
Ⅰ. 1. mess　2. stress　3. ill　4. neighbors　5. fairness
Ⅱ. 1. unfair　句意为“不告诉她事实是不公平的”，故用fair的反义词unfair（不公平的）。
2. likes　neither...nor...连接两个并列主语时，谓语动词与靠近的主语保持一致。his father为单数，用第三人称单数形式，故填likes。
3. to buy　There is no need for sb. to do sth. 意为“对于某人来说做某事是没有必要的”，故填to buy。
4. waiting　mind doing sth. 意为“介意做某事”，为固定搭配。
5. dropped　由从句中的spent为过去式可知主句用一般过去时，故填过去式dropped。
Ⅲ. 1. B　help with sth. 意为“帮助做某事”。句意：我认为孩子应该在家里帮助做家务。
2. D　由上句句意“我认为做家务是父母的工作”及下句中“孩子也应该在家里做家务”可知，答案为I disagree（我不同意）。故选D。
3. B　Could I... 是表示有礼貌地征询许可的问句，其回答不用could，而用can，故排除A、D两项；由后句句意“你必须先打扫教室”可知B项符合题意。
4. A　take out the rubbish意为“倒垃圾”。
5. C　It’s +形容词+ of/for sb. to do sth. 意为“对某人来说做某事是……的”，是固定句式。当形容词是表示人的性格特点的词时，用of；而necessary是用来描述事物特征的形容词，所以用介词for。故选C。
Ⅳ. 1. Could I　2. Could you please；Sorry，I can’t
3. Yes，sure　4. Yes，you can
Ⅴ. 1. Could I　2. make my bed　3. neither did I　
4. borrowed，from　5. as soon as
Ⅵ. One possible version：
Dear class，
　　Here is a report about what chores students do at home. There are 35 students in our class. Fourteen students think doing chores makes them happy. They usually make their beds and take out the rubbish. Ten students like to do the dishes and walk the dog. They think these chores are interesting. Seven students often help their parents cook and wash clothes. They think housework is boring but they can learn to look after themselves by doing it. The other four students never do chores at home，because they think it is tiring.
Yours，
Liu Na
