【知识点详解】
1. 英语能力：题目中提到的"The girl can _________ English and she can _________ it in English very well."，这是在考察学生对于speak和say这两个动词的用法。speak通常用于表示说某种语言，而say则强调说出具体的内容。所以正确答案是D. speak, say。
2. 可能性表达："( ) 2. _________ you can join us."，此题考察的是可能性的表达方式，"Maybe"是副词，意为“可能”，符合题意；而"May be"和"Can be"都是情态动词加动词原形的结构，不适用于此处。因此，正确答案是A. Maybe。
3. 帮助某人做某事："Let me help you _________ swimming?"，此题考查的是固定搭配"help sb. with sth."，意为帮助某人做某事。所以正确答案是B. with。
4. 不定式作后置定语："Ann is always the last one _________ in her class."，这里的"the last one to do sth."是不定式作后置定语，表示“最后一个做某事的人”。因此，正确答案是C. to come to school。
5. 听与听见的区别："I _________ my teacher carefully, but I can't _________ him."，listen to表示听的动作，hear则表示听到的结果。所以正确答案是C. listen to, hear。
6. 讲故事的表达："His grandmother always _________ him funny stories."，tell stories是讲故事的固定搭配，故正确答案是D. tells。
II. 句型转换：
1. 就划线部分提问："My house is on Green Street."，对地点提问用疑问词where，所以是"Where is your house?"
2. 同义句转换："It's time for lunch."，可以改为"It's time to have lunch."
3. 同义句转换："Miss Gao is our English teacher."，可改为"Miss Gao teaches us English."
4. 一般疑问句："I had a busy weekend ."，过去时的一般疑问句要借助助动词did，所以是"Did you have a busy weekend?"
5. 一般现在时的否定句："He is doing his homework now ."，用every day替换now并改为否定句，要用doesn't，所以是"He doesn't do his homework every day."
III. 完成句子：
1. "你想要多大的汉堡包？"应为"What size hamburger would you like?"
2. "它在邮局的对面。"应为"It's opposite the post office."
