()1. — What is Mike doing?
— He .

A.running
B.swims in the river
C.is walking

C

问句是现在进行时（结构：be + doing），答句需用相同时态，结构为“主语+be动词+现在分词”。A选项缺be动词，B选项是一般现在时，C选项符合现在进行时结构，正确。

()2. — do you like spring?
— I can fly kites.

A.Why; Because
B.Why; And
C.Which; Becausse

A

询问原因用疑问词Why，回答原因用Because，符合语境的是选项A。

()3. There is a call you.

A.for
B.on
C.at

A

本题考查介词固定搭配。“There is a call for sb.”是固定表达，意为“有某人的电话”，因此选介词for。

()4. —?
—They are listening to music.

A.What do they do
B.What are you doing
C.What are your grandparents doing

C

答句为现在进行时，主语是they。A选项是一般现在时，询问职业，不符合；B选项主语是you，答句应对应I/we，不符；C选项主语是your grandparents（复数），时态为现在进行时，与答句匹配，故选C。

()5. Apples are sweet fall.

A.on
B.in
C.at

B

英语中表示“在某个季节”用介词in，fall意为“秋天”，属于季节，因此选B。

二、为下列问句找到相应的答句。

1-E，2-C，3-D，4-A，5-B

1. 问句询问周末的活动，对应答句E（一般现在时，说明周末常做的事）；2. 问句询问儿童节的日期，对应答句C（具体日期）；3. 问句询问最喜欢的季节，对应答句D（说明喜欢的季节及原因）；4. 问句是现在进行时的一般疑问句，对应答句A（否定回答及实际要做的事）；5. 问句询问正在做的事，对应答句B（现在进行时，说明正在做的动作）。

三、连词成句。

3. season like do best Which you

4. birthday My is in June grandpa's

1. I often pick up leaves on the weekend. 2. He is making a snowman. 3. Which season do you like best? 4. My grandpa's birthday is in June. 5. My brother is cooking dinner in the kitchen.

1. 本题考查一般现在时的陈述句，主语为I，副词often放在实义动词前，短语pick up作谓语，leaves作宾语，on the weekend作时间状语，按正确顺序排列单词即可。2. 本题考查现在进行时的陈述句，结构为“主语+am/is/are+现在分词+其他”，He是主语，is making是现在分词结构，a snowman作宾语。3. 本题考查Which引导的特殊疑问句，结构为“Which+名词+助动词+主语+动词+其他”，Which season后接助动词do，主语you，like best。4. 本题考查名词所有格的用法，grandpa's修饰birthday构成主语，后接be动词is，时间状语in June。5. 本题考查现在进行时的陈述句，My brother是主语，is cooking是现在分词结构，dinner作宾语，in the kitchen作地点状语。
