改错：Did he （go） to school yesterday?
昨天他上学了吗?
因为前面用了助动词did,因此went要变回原形go.Look!She _____(run)now.but she ___(not run)yesterday这个该怎么填Look! She (is running) now. But she (didn't run) yesterday.瞧！她现在正在跑步。但她昨天没跑步。解释：前一句是现在进行时。后一句是过去时。最后一题：There ____(be)a lamp on the desk,it ____(be not)there just nowThere (is) a lamp on the desk, it (wasn't) there just now.现在桌上有盏灯，刚才它不在那儿。
