are cutting ,cut
根據(jù)look 判斷,第一空用現(xiàn)進(jìn),再根據(jù)第二句中的they,可知第一空填are cutting 而不是is cutting . 根據(jù)過去時(shí)間 last sunday判斷第二空用過去式cut . this was his first visit ___ china ,he said the trip ____china was very interesting.
A.to,to B.to ,for選Awho 是代詞。應(yīng)用三單？在不知道多少人的情況下,用三單,如: Who is knocking at the door ? 但此句后面有個(gè)they,因此要用are cutting .
look who ______(cut) trees over there?--they ______ down a lot of trees last sunday.
look who ______(cut) trees over there?--they ______ down a lot of trees last sunday.
