【題目】I used to online a lot, but now I am used to with my friends.
A.chatting; study
B.chat; studying
C.chat; study
D.chatting; studying

【答案】B
【解析】句意:我過去常常在網(wǎng)上聊天,但是現(xiàn)在我習(xí)慣了和我的朋友們一起學(xué)習(xí)。chat聊天,是一個動詞;study學(xué)習(xí),動詞。第一個空前是短語used to do sth.過去常常做某事,后面跟動詞原形;第二個空前是句型是be used to doing sth.習(xí)慣于做某事,應(yīng)該用動名詞形式。由此可知選B。
