当堂达标（见导学案“当堂达标”）
答案与解析：
Ⅰ. 1. borrow　句意：“我可以借一下你的词典吗？”“对不起，我刚才把它借给了彼得。”borrow意为“借用”，情态动词could后用动词原形。
2. inviting　句意：这个星期五我要邀请我的朋友参加我的生日聚会。invite动词，意为“邀请”，此处有am，所以用现在分词构成进行时，表将来。
3. takes　take out the rubbish意为“倒垃圾”。由every day（每天）知本句用一般现在时，主语Dad为第三人称单数，所以用takes。
4. snacks　句意：我要买一些饮料和点心。snack名词，意为“点心；小吃”，and连接的并列成分应在形式上一致，由drinks为复数知snack也用复数形式。
5. test　test名词，意为“测试”，the English test意为“英语测试”。
Ⅱ. 1. C　Could you please... 是表示有礼貌地请求别人做某事的句型，由答语后句“I’m too busy.（我太忙了）”可知，前句是否定回答；Could you please... 的答语中用can不用could，故选C。
2. C　Could you please... 后接动词原形，故选C。
3. B　invite sb. to +某地，意为“邀请某人去某地”。
4. B　由题意及句子结构可知此处为need to do sth.（需要做某事）。
Ⅲ. 1. invite，to　2. borrow some money　
3. drinks and snacks　4. take out the rubbish
Ⅳ. 1. D　由上句“爸爸，我明天可以邀请我的朋友参加聚会吗？”可知答案为“Of course!（当然可以！）”。
2. C　由下文“I need to buy some drinks and snacks.（我需要买些饮料和小吃）”可知，上文是“你可以借给我些钱吗？”，故选C。
3. E　由上句“噢，我明天要去超市”可知，后句为“我可以给你买一些”，故选E。
4. A　由答语句意“好的，爸爸，我马上就扫地”可知，上句是问“请你扫一下地好吗，汤姆？”。
5. B　由后句句意“不要弄坏任何东西”可知，上句为“要小心所有东西”，故选B。
Ⅴ. 1. By doing some chores at home.
2. He sweeps the floor，cleans the table and walks the dog every day and he also takes out the rubbish on Mondays，Wednesdays and Sundays.
3. Three times a week.　4. Only $20 a week.
