请大家帮帮我,应该选哪项,为什么?谢谢!

我认为选B B,join up

c和d语法都不对啊

associate，connect，link，join

这三个词都含有“连接，联系”之意。associate vt. vi.强调两事物或人之间的联合，合伙，结合，以
达到某种共同的目的，常用句型associate…with…或associate with…或名词短语in association with
。connect vt. vi.常用connect to / with，指两人或事物在物质上或人事关系上“联结，连接”，但保
持各自的特性。Link vt. vi. 也表“连接，联结”之意，但比connect意味更强，强调联结的紧密性。
Join vt. vi. 表示用（线，绳子，桥梁等）将两个或两个分离的事物或两点联结，联合，常用句型：
join sth. to sth.；join things together /up 。
