　　丁丑，俞填在居庸关剽掠，居民窃走来告。上^[注]曰：“居庸关山路险峻，北平之襟喉，百人守之，万夫莫窥。今俞填得之，利为彼有，势在必取。譬之人家后户，岂容弃与寇盗？今乘其初至，又兼剽掠，民心未服，取之甚易；若纵之不取，彼增兵守之，后难取也。”乃命徐安往讨之。安攻拔其城，俞填走怀来，依宋忠。捷至，上曰：“使贼知固结人心，谨守是关，虽欲取之，岂能即破？今天以授予，不可失也。”乃令吴玉守之。

　　上语诸将曰：“宋忠拥兵怀来，居庸关有必争之势，因其未至，可先击之。”诸将皆曰：“贼众我寡，难与争锋，击之未便，宜固守以待其至。”上曰：“非公等所知。贼众新集，其心不一；宋忠轻躁寡谋，狠愎自用，乘其未定，击之必破。”

　　癸未，上率马步精锐八千，卷甲而进。甲申，至怀来。先是，获贼间谍，言宋忠诳北平将士云：降家皆为上所杀，委尸填满沟壑，宜为报仇。将士闻之，或信或否。

　　上知之，乃以其家人为前锋，用其旧日旗帜。众遥见旗帜，识其父兄子弟成在，喜曰：“噫！我固无恙。是宋都督逛我也，几为所误！”遂倒戈来归。宋忠余众，仓皇列阵。未成，上麾师渡河，鼓噪直冲其阵。宋忠大败，奔入城。我师乘之而入，宋忠匿于厕，搜获之。并擒俞填，斩孙泰于阵，余众悉降。

　　诸将已得宋忠颇有喜色上曰宋忠本庸材以利口取给谄谀 * * 恶货赂得官才掌兵柄便尔骄纵此辈荧惑小人视之如狐鼠耳区区胜之何足喜也诸将成顿首称善（选自明·谢黄《后鉴录》卷下，有删改）

All animals must rest, but do they really sleep as we know it The answer to this question seems obvious. If an animal regularly stops its activities and stays quiet and unmoving—if it looks as though it is sleeping—then why not simply assume that it is in fact sleeping But how can observers be sure that an animal is sleeping

They can watch the animal and notice whether its eyes are open or closed, whether it is active or lying quietly, and whether it responds to light or sound. These factors are important clues, but they often are not enough. Horses and cows, for example, rarely close their eyes, and fish and snakes cannot close them. Yet this does not necessarily mean that they do not sleep. Have you ever seen a cat dozing with an eye partly open Even humans have occasionally been observed to sleep with one or both eyes partially open. Animals do not necessarily lie down to sleep either. Elephants, for example, often sleep standing up, with their tusks resting in the fork of a tree. Finally, while "sleeping" animals often seem unaware of changes in the sounds and light and other stimuli around them, that does not really prove they are sleeping either.

Observations of animal behavior alone cannot fully answer the question of whether or not animals sleep. The answers come from doing experiments in "sleep laboratories" using a machine called the electroencephalograph (EEC). The machine is connected to animals and measures their brain signals, breathing, heartbeat, and muscle activity. The measurements are different when the animals appear to be sleeping than when they appear to be awake. Using the EEC, scientists have confirmed that all birds and mammals studied in laboratories do sleep. There is some evidence that reptiles, such as snakes and turtles, do not truly sleep, although they do have periods of rest each day, in which they are quiet and unmoving. They also have discovered that some animals, like chimpanzees, cats, and moles (who live underground), are good sleepers while others, like sheep, goats, and donkeys, are poor sleepers. Interestingly, the good sleepers are nearly all hunters with resting places that are safe from their enemies. Nearly all the poor sleepers are animals hunted by other animals: they must always be watching for enemies, even when they are resting.

According to the research findings mentioned in the passage, reptiles（）

A. such as turtles and snakes cannot close their eyes

B. cannot be studied with an EEC

C. do not sleep in the true sense of the word

D. do not need to rest
