Tom can't play basketball with us．He is showing foreign teachers around school．．

Answer 1

分析 He is showing foreign teachers around school．

解答 答案：He is showing foreign teachers around school．是說湯姆正在做某事用現(xiàn)在進(jìn)行時(shí)am/is/are+doing，主語he，故is，帶某人參觀某地用show sb around sth，故he is showing，外教foreign teachers，故答案是He is showing foreign teachers around school．

點(diǎn)評 在進(jìn)行時(shí)表示正在發(fā)生或進(jìn)行的動(dòng)作．結(jié)構(gòu)是：be （am，is，are）+動(dòng)詞現(xiàn)在分詞形式．  （簡寫：be+動(dòng)詞-ing）
