答案：4. are running
解析：“Karen and I”是復(fù)數(shù)主語，現(xiàn)在進(jìn)行時(shí)結(jié)構(gòu)為“be動(dòng)詞+動(dòng)詞現(xiàn)在分詞”，“be”動(dòng)詞用“are”，“run”的現(xiàn)在分詞是“running”，所以填“are running”。
5. are wearing
解析：“They”是復(fù)數(shù)，現(xiàn)在進(jìn)行時(shí)中be動(dòng)詞用“are”，“wear”的現(xiàn)在分詞“wearing”，故填“are wearing”。
6. is painting
解析：主語“He”是第三人稱單數(shù)，be動(dòng)詞用“is”，“paint”的現(xiàn)在分詞“painting”，填“is painting”。
7. are eating
解析：“We”是復(fù)數(shù)，be動(dòng)詞用“are”，“eat”的現(xiàn)在分詞“eating”，填“are eating”。
8. are building

He is cutting flowers.
2. She borrows books in the library.
3. They practice in the training room.
4. We weld components in the factory.
答案：2. She is borrowing books in the library.
解析：現(xiàn)在進(jìn)行時(shí)結(jié)構(gòu)為“主語+be動(dòng)詞+動(dòng)詞現(xiàn)在分詞+其他”，主語“She”是第三人稱單數(shù)，be動(dòng)詞用“is”，“borrow”的現(xiàn)在分詞“borrowing”，所以改寫為該句。
3. They are practicing in the training room.
解析：主語“They”是復(fù)數(shù)，be動(dòng)詞用“are”，“practice”的現(xiàn)在分詞“practicing”，改寫為現(xiàn)在進(jìn)行時(shí)句子。
