他昨天在工作英语

He is working now.要动名词,即动词+ing

英语是:They went to work yesterday

1.他工作了一整天,但他一点也不累（not at all not a bit) . He works all day,but he is tired not at all .或是He works all day,but he is tired at a bit. 2.汤姆的姐姐是中等身材,但她想要更瘦一点（thinner) Tom's older sister is medium stature ,but she wants to be thinner.

He began to do the work yesterday morning

working ,现在进行时

He is at work now 、 或者He is working now 、

他昨天上午开始做那项工作He began to do the job yesterday morning.He began doing the job yesterday morning.

加 ing . 应该是这样吧。
