3.详细解说
1.“warm sth./sb. up”的意思是“加热，使暖和，使变暖”。例如：Come inside and have a drink. It'll warm you up.(进来喝一杯，暖和暖和。)另外，“warm up”也可以作不及物动词词组，表示“变热，变暖”，例如：With the fire on, the room should soon warm up.(生了火，房间应该马上就会变暖和的。)Once the weather warms up, you can move the plants outdoors.(天气一变暖，你就可以把这些盆栽植物搬到屋外了。)
2.“get a connection”相当于“get connected”，意为“(电话)接通”。“connection”表示“(电话)接通”时，用作可数名词。例如：Sorry，could you repeat that? This is a very bad connection.(对不起，你能再说一遍吗?电话不太通畅了。)其动词形式“connect”也可表示“接通(电话) ”,例如: Could you connect me with/to a number in Paris. please?I can't seem to get through.(你能帮我接通一个电话到巴黎吗?我好像拨不通。)Please hold the line.I'm trying to connect you.(请稍等，我试着帮你接通。)
