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.

enter后面不加介词。save有节约的意思，economize后面加on

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

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...

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。
