1. Bob is a blue T-shirt.
A.wear
B.wears
C.wearing
1. Bob is a blue T-shirt.
A.wear
B.wears
C.wearing
答案
C
解析
题干中已经有be动词is，后面不能再搭配动词原形或者第三人称单数形式，要搭配动词的现在分词形式，构成现在进行时，wear的现在分词是wearing，所以选C。
2. He was short. he couldn't ride his bike well.
A.So
B.Because
C.But
A.So
B.Because
C.But
答案
A
解析
前句“He was short.”（他个子矮）是原因，后句“he couldn't ride his bike well.”（他自行车骑得不好）是结果，用“So”连接表示结果。Because表原因，But表转折，均不符合。
3. I have two dogs. I like so much.
A.it
B.them
C.he
A.it
B.them
C.he
答案
B
解析
题干中提到有两只狗，为复数，因此代词应该用复数形式，选项中只有them为复数形式的代词，指代two dogs。it为单数代词，he为主格单数代词，均不符合题意。
4. John went cycling .
A.next week
B.now
C.last Saturday
A.next week
B.now
C.last Saturday
答案
C
解析
题干中“went”为动词过去式，表明句子时态是一般过去时。A选项“next week”用于一般将来时；B选项“now”常用于现在进行时；C选项“last Saturday”表示过去的时间，用于一般过去时，符合句子时态。
5. is good .
A.Walking; exercise
B.Walks; exercise
C.Walking; exercises
A.Walking; exercise
B.Walks; exercise
C.Walking; exercises
答案
A
解析
本题考查动名词作主语以及不可数名词的用法。"Walking"是动名词形式，可以作主语，表示“散步”这一行为；"exercise"作为“锻炼”时，是不可数名词，没有复数形式。因此，选项A中的"Walking"作主语，后接"is good exercise"表示“是很好的锻炼”，符合题意。
