It _____ four years since we ______to learn English.

A. Is , begin?? B. has been , began??? C. has, been???? D. had been ,began

 

【答案】

B

【解析】

試題分析：句意：自從我們開始學(xué)英語已經(jīng)有四年了。since,自從……，后加過去的時(shí)間點(diǎn)或過去時(shí)態(tài)的句子，是現(xiàn)在完成時(shí)的標(biāo)志詞，表示一個(gè)動(dòng)作從過去就開始了一直持續(xù)到現(xiàn)在。如果主句是一段時(shí)間，也可以用一般現(xiàn)在時(shí)代替現(xiàn)在完成時(shí)。A項(xiàng)，begin的時(shí)態(tài)不正確，故選B

考點(diǎn)：考查冠詞的用法

Junior school students in Harbin，Heilongjiang，had a "long weekend"．They had four days off from Oct．19-22．It was not for any festival，but was caused by serious smog．

The smog was caused by high levels of PM 2．5 in the air．

On Oct．21，Harbin Education Bureau decided to close primary and junior high schools for two days．

??? Beijing started a program on Oct．22 which has a warning system with four levels．The red warning is the highest warning level．It means that the next three days will see serious pollution．

When a red warning is issued（發(fā)布），schools will close．
