—He is not at school now. He ______ Kris with her study at her home.

A. helps B. has helped C. will help D. is helping

Answer 1

【答案】D

【解析】

句意：——我找不到我們的老師。他在哪里？——他現(xiàn)在不在學(xué)校。他正在幫助克里斯在家里學(xué)習(xí)�？疾閯�(dòng)詞時(shí)態(tài)辨析題。now現(xiàn)在，用于現(xiàn)在時(shí)；根據(jù)句意語(yǔ)境，可知用be + doing結(jié)構(gòu)，故選D。
