阅读以下文字，回答下列问题：
睡眠是大脑为维持正常机能而产生的[ ]抑制状态。通过对整个睡眠过程的仔细观察，发现它具有两种不同的状态：其一为脑电波呈现同步化慢波的时相，称为慢波睡眠；其二是脑电波呈现去同步化快波的时相，称为快波睡眠。
人们在刚刚入睡后的睡眠大都属于慢波睡眠。根据脑电波的变化特征，慢波睡眠时相可以分为1、2、3、4期。这四个期代表着睡眠由浅入深的过程。1期：呈现低振幅的脑电波，频率快慢混合，以4～7次/秒的θ波为主。这一时期一般是在睡眠开始或夜间短暂苏醒又入睡之时。2期：也呈现低振幅的脑电波，中间常出现短串的12～14次/秒的梭形睡眠波和一些复合波。这一时期是慢波睡眠的主要成分，代表着浅睡过程。3期：常呈现短暂的高振幅、频率为1～2次/秒的δ波。4期：脑电波也是呈现出高振幅波形且以6波为主，代表着深睡状态。3期和4期仅有量的不同而无质的差别。通常认为，4期慢波睡眠具有促进精力和体力恢复的功能。
快波睡眠是睡眠过程中周期性出现的一种激动状态，其脑电图与觉醒时相似，呈现低振幅的去同步化快波，也称为异相睡眠。并且，由于这种类型的睡眠常伴随着眼球的快速运动，所以也被称为快速眼球运动睡眠。快波睡眠可能与脑的发育和记忆的巩固有关。

以下哪项不能作为慢波睡眠分期的依据( )

A．脑电波振幅

B．脑电波频率

C．脑电波形

D．入睡时间

Thank you for your card. I'm glad you're having a good time, but I'm not surprised.

Washington D.C. is wonderful at this time of year.

I would like you to come to my place and meet my people at the end of your journey.

You can't leave America without visiting New York. My brother's hobby, as you know,

is taking pictures. He has a big album(相册)of pictures of the United States and of New

York. I'm sending some of them to you. When you look at them you'll understand why

New York is a city of islands. In fact it lies on three big islands: Manhattan, Staten Island

and Long Island. There are many small islands in the city.

The most expensive part of New York is Manhattan. This island is famous for its

skyscrapers(摩天大楼).Broadway is a famous street in New York. It is known for its

theatres and you can see wonderful shows there.

and have their art classes there. School children often visit the Bronx Zoo. It is the largest

of the New York City zoos. It opened in 1899 and since then has always been a favorite

place for animal lovers and children.
