(2) who was born in 1861是一个非限制性定语从句。非限制性定语 从句起补充说明作用，省去后不影响主句的意思，并且常用逗号与主句分开，翻译时常译成并列的分句。如， We all like Bob very much, who is a lively boy. 2. Dr. Naismith divided the men in his class into two teams and taught them to play his new game. 奈史密斯博士把他的班里的男生分成两队，并教他们玩他的新运动。 (1) divide 及物动词，意为“分开；分散”，指把整体分成若干部分。divide...into 意为“把……分开”，其被动结构为be divided into，意为“被分为……”。如， Let’s divide ourselves into several groups. (2) teach sb. to do sth. 意为“教某人做某事”。如， My grandmother used to teach me to make cookies by hand. 3. At the same time, they need to stop the competing team from getting the ball into their own basket. 同时，他们需要阻止对方把球投到他们自己的篮筐里。 (1) at the same time 意为“同时”，其中same为形容词，意为“相同的”，使用时前面一般要加定冠词the。如， You should avoid making the same mistakes. (2) stop...from doing sth. 意为“阻止……做某事”。其同义短语为prevent/keep...from doing sth.。如，The guard stopped the stranger from getting into the hall. 【注意】在主动语态中stop...from doing sth.里的from可以省略，但在被动语态中不能省略。 如，The forest can stop the water (from) washing the earth away. 4.

(2) 主谓一致原则：not only...but also…连接两个并列主语时，谓语动词要和与其最近的主语保持人称和数的一致。如， Not only the students but also the teacher was against the plan. 5.
