But let‘s say you meet someone and from the first moment you set eyes on them, they seem to have a strong power over you.
你看到她的那一刻，她似乎就对你有一种魔力
That is not simply hitting it off. That is what we call love at first sight.
这不是简单的一见如故，这就是我们所说的一见钟情
Getting closer to the object of you affections.
接近你的爱慕对象
When you are smitten with someone, you think of that person all the time, you hang on every word they say. They are your one and only.
当你为某人着迷，你时刻想起她，你认真听她说的每句话。
If you meet someone and fall head over heels in love, you fall in love hard. True love can sweep you off your feet. Love can take your breath away.
如果你遇见某个人，并且爱的死心塌地，也就是说你深深的陷入爱情。真爱会让你神魂颠倒，爱会让你无法呼吸
A match made in heaven simply means two people have much in common or that each person makes the other better. Another experssion that means the same thing is soul mate.
天作之合只是意味着两人有很多共同点，两人能够互相成就彼此。另一种意思相同的表达是灵魂伴侣
If you love someone completely, you can say you love them with all your heart and soul.
如果你彻底爱上某个人，你可以说你全身心地爱着她
If your relationship hits a difficult period, you can say it is on the rocks.
如果你们的关系陷入艰难时期，你可以说关系触礁。（这种说法来源于划船运动）
It‘s better to have loved and lost than never to have loved at all.
