当堂达标(见导学案“当堂达标”)
答案与解析：
Ⅰ. 1. his　由空格后的名词短语telephone number可知此处应用形容词性物主代词，he对应的形容词性物主代词是his。
2. hers　空格后无名词，故此处用名词性物主代词hers。
3. mine　mine是名词性物主代词，此处相当于my keys。
4. me　excuse me为固定搭配，意为“劳驾；打扰了”。
5. yours　空格后无名词，故应用名词性物主代词作表语。句意：这些书是你的吗？
6. dictionaries　根据句中系动词are可知，此处用名词的复数形式，故用dictionary的复数dictionaries。
Ⅱ. 1. A　当打扰别人或有事需要别人帮忙时，常用excuse
me。
2. B　在回答Is this/that... 时，常用it来代替this/that。根据答语的后一句可知要用否定回答。
3. B　由问句句意“这是你的夹克衫吗？”及第一个空格后的名词jacket可知，第一个空格用形容词性物主代词your；第二个空格后无名词，此处应用名词性物主代词；由“或许它是迈克的”可知此处表示“不是，我的在我的包里”。故选B。
