Question

【題目】It is the first time that Chinese teachers ________ in schools across Britain to introduce Chinese-style maths lessons and teaching approaches.

A. taught B. teach

C. have taught D. had taught

Answer 1

【答案】C

【解析】

考查現(xiàn)在完成時(shí)。句意：這是中國教師首次在英國各地的學(xué)校教中國式的數(shù)學(xué)課和教學(xué)方法。The first time that表示“第一次……”，引導(dǎo)表語從句時(shí)，如果主句的系動(dòng)詞是一般現(xiàn)在時(shí)，從句用現(xiàn)在完成時(shí)，故C項(xiàng)正確。
