改錯：Did he （go） to school yesterday?
昨天他上學了嗎?
因為前面用了助動詞did,因此went要變回原形go.Look!She _____(run)now.but she ___(not run)yesterday這個該怎么填Look! She (is running) now. But she (didn't run) yesterday.瞧！她現(xiàn)在正在跑步。但她昨天沒跑步。解釋：前一句是現(xiàn)在進行時。后一句是過去時。最后一題：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.現(xiàn)在桌上有盞燈，剛才它不在那兒。
