Do you know how to be street smart? Being street smart means knowing how to keep yourself safe from strangers when you’re alone or with other kids. 1 .

Most strangers aren’t dangerous and wouldn’t do anything to hurt kids. Unfortunately, though, some strangers can be dangerous, and it’s impossible to tell who’s OK and who’s not. 2That’s why it’s important to follow these safety rules all the time.

Make your whereabouts known.

The adult who’s taking care of you needs to know where you are and when you’ll be coming home.

3It’s more fun and safer to do things with friends. Traveling with a friend whenever you can is a good idea, and traveling with a group of kids is even better.

4Safe spots are places where you can stop if you need help, like the houses of kids you know, the houses of your parents’ friends, police stations, libraries, and fire departments. When you’re walking or riding your bike, make a mental note of the safe spots along your route. That way, you’ll know where they are in case you ever need one.

5You’ve probably been told lots of times that you should not yell and keep quiet. But when you think you might be in danger, it’s the perfect time to be noisy! If a stranger approaches you, follows you or tries to grab you, yell as loudly as you can and try to get away. People in the area will hear what’s going on and help you , so make plenty of noise.

E. Go to school with your friends.

F. Make a lot of noise if you’re scared.

G. A dangerous person doesn’t necessarily look scary.

To wash yourself, you take a bath(洗澡) or a shower. Animals need to keep clean, too. How do animals clean themselves?

Cats lick（舔）themselves to keep their fur clean. Have you ever watched a pet cat clean itself?

Elephants take baths much as you do. But instead of jumping into the tub（浴缸）, they walk into a river or lake.

Pigs also like to roll around in water. This keeps them clean and cool. If there is no clean water, they will roll in mud（泥）on a hot day. They do this to cool off. Pigs do not really like mud. They are happier in a nice, clean pond(水池).

Bats have a funny way to keep clean. They lick their thumbs to clean their ears!

Guess how polar bears clean themselves. They use snow, of course!

Some animals take baths in dust instead of water! The wombat(毛鼻袋熊) is an Australian animal with lots of fur. To get clean, it lies down. Then it covers itself with sand!

Birds clean themselves in many ways. Sometimes they wash in water. That’s why some people put birdbaths in their yard. At other times birds take dust baths, just like wombats. Birds also use their beaks（喙）to keep their feathers clean. They use their beaks the way you use a comb.

Sometimes a bird has itchy bugs（发痒的虫子）in its feathers. Birds may use ants to help them clean off the bugs. A bird will lie down on an ant nest. Then the ants will crawl on the bird. The ants make a kind of bug spray（喷雾）on the feathers;. Then the itchy bugs die!

Birds take baths in something else besides dust and ants! Some birds take “smoke baths” They sit on chimneys. They wave their wings in the smoke!

How to keep screens from ruining your vision

Laboratory studies　 have shown that prolonged exposure　 to high-intensity blue light damages retinal (视网膜的) cells in mice. But epidemiological (流行病学的) studies on real people tell a different story.

So,1.Human eyes are different from rodent (啮齿动物) eyes. We have protective elements, such as macular pigments and the natural blue-blocking ability of the crystalline lens (晶状体).2. Just because blue light isn’t harming your retina doesn’t mean your electronic devices are harmless. Because of its wavelength, blue light does disrupt healthy sleep physiology. Mounting evidence suggests that3.It　 also robs　 you of restorative　 rapid-eye-movement　 sleep,　 dulls　 focus,　 and diminishes 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 defines this rule as taking a 20-second break every 20 minutes to look at something 20 feet in the　 distance. This will allow your eyes to blink and relax. Third,5. This way will reinforce the　　 body’s natural tears and keep the eye’s surface hydrated.

A. why does it damage our human retinal cells?

B. These structures absorb blue light before it reaches the delicate retina.

C. why is there difference between blue light’s effects on rodent eyes and human eyes?

D. screen time before bed increases the time it takes to fall asleep.

E. There are ways to make your screen viewing more comfortable and more conducive to sleep.

F. use lubricating eye drops before extended computer use.

G. we should decrease screen time before bed.
