In this period，we have learned：
1. New words and phrases：full，swing，maybe，least，swing dance，at least
2. Sentences：...next week is quite full for me...
How come
What kind of dance are you learning
Oh，I have to play tennis with my friends.
3. Grammar：the adverbs of frequency
当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. A　根据答语“Once a week.”可知问句是询问做某件事情的频率，因此用How often。
2. C　hurry up意为“快点”；put up意为“举起，张贴”；stay up意为“熬夜”；wake up意为“叫醒”。根据前句句意“你看上去很疲惫”可推知答语句意为“我昨天晚上熬夜看足球赛了”。stay up符合句意，故选C。
3. B　该问句为一般现在时，由助动词does可知句中谓语动词应用原形，故排除A、C两项；答句与问句时态要一致，he作主语，谓语动词watch用第三人称单数形式watches，故选B。
4. B　at last意为“最后”；at least意为“至少”；at times意为“有时”；at present意为“目前”。由句意“这个飞机模型不如我叔叔的好，但至少它是我自己做的”可知选B。
5. A　maybe意为“也许，可能”，常位于句首；may be意为“也许，可能”，常位于句中，两者可以相互转换，may为情态动词，意为“也许，可能”；might是may的过去式，语气比may要弱。根据前句“我也不确定”可推知后句句意为“或许在教室里”，又因位于句首，maybe符合句意，故选A。
Ⅱ. 1. often　how often意为“多久一次”，对频率进行提问。
2. hardly ever　句意：这儿几乎从不下雨，通常天是晴朗暖和的。
3. every day　句意：我的一些朋友每天锻炼，几乎从不吃垃圾食品，但是其他人每天吃垃圾食品。
4. never　句意：我不会游泳，因此我从来不去游泳。有时我和朋友一起跑步。
5. always　句意：他总是6点钟起床。
Ⅲ. 1. always　2. usually　3. sometimes　4. often
5. times　6. hardly　7. never　8. for　9. although　10. every
Ⅳ. 1~5　BBCBB
