My home is close to my home. 同义句My home is near to my home.

My home is close to my home. 同义句My home is near to my home.
为什么不是My home is near my home.
close to 不是等于near吗?那为什么要有to.实在不明白

near 这词有时候不需要to,有时候必须加to,有时候则可要可不要,I.near用作形容词,意为“近的;临近的”,常用作表语或定语.例如:
The post office is quite near.邮局(离这儿)非常近.
Nobody was near.没人在附近.
注意near与close相对,当表示空间或时间上的“接近的”时,二者意思几乎一样.只不过near在程度上要比close弱,near通常没有“紧接”的意思,而close有“紧接”和“近在身旁”的意思.试比较:
Can you tell me the nearest way to the station?你能告诉我去车站最近的路吗?
He has a near opinion with ours.他的意见与我们的意见接近.
He is a near friend of mine.= He is a close friend of mine.他是我的一位亲密朋友.
II.near也可用作副词,但初学者容易误认为near的副词形式是nearly(差不多;大约;几乎).near指(时间.空间)“接近;近”.例如:
Spring draws near.春天临近了.
My parents line quite near.我父母住的地方离这里很近.
I am standing just near enough to hear what they are saying.我站得很近,正好能听到他们说什么.
III.near与near to
near可用作介词,near to或nearest to既可视作复合介词,也可把near或nearest分别看作near to和nearest to的省略.当表示空间上的“接近”时,用near与near to都行.例如:
She is sitting near(to) me.他坐在我的附近.
The cinema is near the supermarket.电影院在超级市场附近.
