三、给下列句子排序。
()Hi, John! What do you usually do after school?
()Of course.
()Hi, Chen Jie. This is John.
()Thanks, let's play together.
()I play the piano. Can I join(加入) you?
()I usually play football with my friends. How about you?

2；5；1；6；4；3

这是情景对话排序题，我们按照日常对话的逻辑梳理顺序：
1. 对话开篇首先是向陈杰介绍约翰，对应句子：Hi, Chen Jie. This is John.
2. 接着陈杰向约翰打招呼，询问他放学后通常做什么，对应句子：Hi, John! What do you usually do after school?
3. 约翰回答自己通常和朋友踢足球，同时反问陈杰的情况，对应句子：I usually play football with my friends. How about you?
4. 陈杰回应自己弹钢琴，并且询问能不能加入约翰，对应句子：I play the piano. Can I join you?
5. 约翰欣然同意对方的请求，对应句子：Of course.
6. 最后陈杰表达感谢，提议一起玩，对应句子：Thanks, let's play together.

四、读句子,选择最合适的回答,将字母填在括号里。
()1. What subjects do you have today?
()2. What's your favourite subject?
()3. Do you have science this morning?
()4. What do you like doing in art class?
()5. What do you want to be in the future?
()6. Can you play the flute?

1.B 2.C 3.A 4.D 5.F 6.E

我们可以根据问句的含义和句式特点匹配对应的答句：
1. 问句“What subjects do you have today?”意思是你今天有什么科目，答句需要回答具体的科目，对应B选项。
2. 问句“What's your favourite subject?”意思是你最喜欢的科目是什么，答句需要回答自己最喜欢的科目，对应C选项。
3. 问句是Do引导的一般疑问句，答句需要用Yes/No搭配助动词do来回答，对应A选项。
4. 问句“What do you like doing in art class?”意思是你在美术课上喜欢做什么，答句需要回答美术课上的活动，对应D选项。
5. 问句“What do you want to be in the future?”意思是你未来想成为什么，答句需要回答自己未来的职业理想，对应F选项。
6. 问句是Can引导的一般疑问句，答句需要用Yes/No搭配情态动词can来回答，对应E选项。

()1. My favourite subject is . I like studying plants.

A.PE
B.science
C.art

B

根据句子后半句“我喜欢研究植物”，研究植物属于科学学科，A选项体育、C选项美术都不符合题意，因此选B。
