Question

两个选择题

1，He was still smilling when the door opened and his wife
entered in enter
这道题答案是enter，为什么不能用enter in?

2，The goverment is trying to persuade people to ____ money
save economize
这道题为什么不能用economize
save 也有节约的意思？政府试图呼吁大家存钱！？

Answer 1

1. enter本身就含有了“come in”的意思。所以再加上in的话就是含义重复了。

2. save money = economize = 节约钱
这道题和第一题有些像，economize也是本身就带有"save money"的意思了，要么用economize什么都不加，要么用save加上money.

Answer 2

答：
1. 这是《新概念英语》第二册第31课 success story 成功者的故事
原文是：
He was still smiling when the door opened and his wife came in
不知道你的选择题目是谁出的？原题是怎样的？用entered in不对。用entered也不对！用enter就更错了。 我错了，entered可以作不及物动词=came in

Answer 3

1.enter 本身就有“进去，进入到里面的意思” 故选用enter。（请问你有见过enter in的语法搭配吗？）
2.save有安全等的意思，当它作为动词的时候有节约，节省，储存的意思。例如“save water”节约用水“，save maney与save water一样是固定搭配短语，表示”存钱“的意思。to save money
save economize=存钱以拯救经济。而”economize“作为副词是表示”有效的利用“。作为动词时是”节省，节省开支“后面是不接maney的。

Answer 4

大体上来说enter是个及物动词，所以当进入讲时不用加in
第二题，save本身就有救，挽救，节省的意思，如果说存钱的话更常用的应该是deposit

Answer 5

enter后面不加介词。save有节约的意思，economize后面加on
