In the shrt time Steve and Zach had been inside their tent packing their tls, wind-blwn flame had skipped frm the tp f ne tree t anther. The lng dry summer had turned the frest int a tinderbx.
“Let’s g! We can make it back t the river we crssed tday! ” Steve kept Brady n the lead and their heads dwn against the fire-wind. But Brady barked a sharp warning. Ahead f them lay a thick curtain f smke acrss the track. They wuld never make it thrugh that. The dg was pulling at his lead trying t draw them away frm the smke, and yet Steve was uneasy. It seemed t him that they were mving away frm the river.
Suddenly，Zach cried. “Zach!” Steve shuted. “Are yu OK? Where are yu?” Then Brady pulled Steve dwn a sharp slpe(斜坡).At its base, Zach was rubbing his ankle.
As Steve helped his friend t his feet, Brady lifted his head and snuffed (嗅）the smke-laden wind. Next mment, the dg bunded away and disappeared. The bys shuted fr him, but he didn’t cme back. Steve culdn’t blame Brady fr panicking. He himself wanted t run even thugh he didn’t have a clue which way t.
Steve and Zach hadn’t gne far when there was a familiar bark, and Brady came bunding, stpped directly in frnt f Steve and hit him with his head, pushing him back tward the slpe they’d just climbed. But Steve didn’t get it. Then Brady grabbed the by’s jeans and started pulling. The message was clear, but Steve hesitated. Of curse he remembered Brady saving his uncle’s life when the dg was much yunger. Was he still sharp enugh t get them thrugh this?
Nearby, a pine went up in a whsh f smke. Brady pulled again, urgently. “OK, the big guy,” Steve gritted his teeth(咬紧牙关). Brady led them back dwn the slpe and int the trees. Nt far frm them fire was tuching underbrush. Several times the big dg stpped. Often he changed directins. Steve was s tired that he just wanted t rest, but Brady wuldn’t have it. The dg bullied bth bys int ging n. Steve had n idea hw lng they’d walked. He was almst numb when he heard it—the wnderful sund f rushing water!

Every animal sleeps, but the reasn fr this has remained fggy. When lab rats are nt allwed t sleep, they die within a mnth. 1
One idea is that sleep helps us strengthen new memries. 2 We knw that, while awake, fresh memries are recrded by reinfrcing (加强) cnnectins between brain cells, but the memry prcesses that take place while we sleep have been unclear.
Supprt is grwing fr a thery that sleep evlved s that cnnectins between neurns (神经元）in the brain can be weakened vernight, making rm fr fresh memries t frm the next day. 3 .
Nw we have the mst direct evidence yet that he is right. 4 The synapses (突触）in the mice taken at the end f a perid f sleep were 18 per cent smaller than thse taken befre sleep, shwing that the cnnectins between neurns weaken while sleeping.
If Tnni’s thery is right, it wuld explain why，when we miss a night’s sleep，we find it harder the next day t cncentrate and learn new infrmatin—ur brains may have smaller rm fr new experiences.
Their research als suggests hw we may build lasting memries ver time even thugh the synapses becme thinner. The team discvered that sme synapses seemed t be prtected and stayed the same size. 5 “Yu keep what matters,” Tnni says.
A. We shuld als try t sleep well the night befre.
B. It’s as if the brain is preserving its mst imprtant memries.
C. Similarly,when peple g fr a few days withut sleeping, they get sick.
D. The prcesses take place t stp ur brains becming laded with memries.
E. That’s why students d better in tests if they get a chance t sleep after learning.
F. “Sleep is the price we pay fr learning,” says Giuli Tnni, wh develped the idea.
G. Tnni’steam measured the size f these cnnectins, r synapses，in the brains f 12 mice.
