Let’s leave the things as they are __ and we can always make

Let's leave the things as they are __ and we can always make changes later on if necessary
A for the present
B on the present
C to the present
D up to the present
for the present不是作状语吗？怎么能放在they are后面？
B on the present 有此词组吗？
C to the present
D up to the present都是做状语吗？

A
for the present 暂时
我们先把东西暂时这么摆着,以后有必要的话可随时调整
再问： 谢谢你的回答 for the present不是作状语吗？怎么能放在they are后面？ B on the present 有此词组吗？ C to the present D up to the present都是做状语吗？ 希望能进一步解释，谢谢！
再答： 这是个由并列连词and 连接的并列句。有两个分句 1.Let's leave the things as they are _for the present 2.we can always make changes later on if necessary 时间状语置于句尾不算怪事吧？
再问： For the present we are made a general checkup.目前，我们正做总的检查。 I've got enough money for the present.我的钱暂时够用。 Iii. patience for the future, not instant gratification for the present.忍耐等候将来,不是现在立时的满足。这些都是做状语的，并没有放在are后面用。怎么解释呢？
再答： 首先你要知道： Let's leave the things as they are 即便没有时间状语， 它本身已经很完整了。 这里for the present 作为时间状语置于句尾是肯定没问题的。置于说我什么是在they are 之后， 那只是个巧合。你也可以把for the present 置于句首呀？ For the present ,let's leave the things as they are . 明白？
