They were fun to read. Yet his books sometimes dealt with serious subjects including equality..请问:1.to read 在这里是什么成分? they是指书吗, read主动表被动?2.为什么subject的定语用including,而不是included?
我最喜欢的课程是英语和数学(汉译英)。下面哪句是对的?1.I favourite subjects is English and Maths.2.I favourite subjects are English and Maths.3.I favourite two subjects are English and Maths.
