“加”用plus,and或add表示;“等于”用is,make,equal等词表示。 2+3=? 可表示为: How much is two plus three? 2+3=5 Two plus three is five. Two and three is equal to five. Two and three make five. Two added to three equals five. If we add two to/and three, we get five.可见,add是动词:vt. 增加, 添加, 计算...总和, 补充说, 又说 vi. 加, 加起来, 增添, 做加 plus 作相加解时,它是介词,后面不能加其它东西. adj. 正的, 加的 n.正号...
