David knew the waterfall was coming. It wasn't his first visit to the river in central California. He figured he would hop out of his raft into the sallow water, rappel down the rocks (沿岩壁下降)on either side of the fall, and continue on his way, as he had on a previous trip.
But this year was different. Heavy snow and spring rains had turned the usually manageable falls into something fierce. And this year, instead of his friends, David's companions were his girlfriend, Sara, and his l3-year-old son, Hunter. As the three of them approached the falls late in the afternoon of the third day of their camping trip, David could tell from the increasing roar of water in the narrowing valley that they were in serious trouble. There was no way they 'd be able to rappel down the rocks as planned.
They could wade (蹚水) to the shore, but would anyone find them there? They had no phone service, and they hadn't seen a single person in the past three days. And David knew they'd be sharing the ground there with snakes and mountain lions.
As he wondered what to do, David hit on a bit of luck he heard voices coming from the other side of the fall. He yelled, but the sound of the rushing water drowned him out.
We had to do get these people a message, David thought. He caught a branch and pulled out his pocketknife to carve“Help" in it. Then he tied a rope to it so the people would know it wasn't just any branch. He tried flying it over the falls, but it floated away in the wrong direction.
Then he spotted his green water bottle David grabbed it and carved “Help!” on it Sara also reminded him that he had a pen and paper, which she'd brought to play games with, in his backpack.
David knew it was just an attempt. But he wrote down“6- 15-19 We are stuck here at the waterfall. Get help please”and pushed the note into the bottle.
Paragraph l:
This time, his throw over the waterfall was perfect.

Laboratory studies have shown that prolonged exposure to high intensity blue light damages retinal (视网膜的) cells in mice.1.So, why is there the disconnect between blue light's effects on rodent(啮齿类动物) eyes and human eyes?
2.We have protective elements, such as macular pigments (黄斑色素) and the natural blue-blocking ability of the crystalline lens (晶状体). These structures absorb blue light before it reaches the delicate retina.
Just because blue light isn't harming your retina, it doesn't mean your electronic devices are harmless.3.Mounting evidence suggests that screen time before bed increases the time it takes to fall sleep. It also robs you of restorative rapid-eye movement seep, dulls focus, and reduces brain activity the next day.
4.
First, turn off your electronic devices before bed. Outside of the bedroom, when you do look at your screens, lower the brightness.
Second, follow the“20-20-20”rule The American Optometric Association(美国验光学会) defines this rule as taking a 20-second break every 20 minutes to look at something 20 feet in the distance. 5.
Third, use lubricating eye drops before extended computer use. This method will build up the body's natural tears and keep the eye's surface water-bearing.
A.This will allow your eyes to relax.
B.Human eyes are different from rodent eyes.
C.That's why it's so important to have your eyes tested regularly.
D.Because of is wavelength, blue light dos disrupt healthy sleep physiology (生理机能).
E.But epidemiological (流行病学的) studies on real people tell a different story.

G.There are ways to make your screen viewing more comfortable and more helpful to seep.
