AG600 seaplane’s test flight

Kunlong, China’s homegrown AG600 large amphibious aircraft, conducted its first sea-based test flight on

Sunday morning, marking a new milestone in the program.

The AG600 is China’s second amphibious aircraft, after the SH-5, which was developed in the 1970s for

military purposes and has been retired for a long time.

These specifications make it the world’s biggest amphibious aircraft, surpassing Japan’s ShinMaywa US-2 and

Russia’s Beriev Be-200.

Once in service, it will put an end to the absence of a large rescue aircraft in China and will be very useful in

the national emergency rescue and disaster relief systems.

Where doyou usually put your toothbrush?Do you keep it in the bathroom? How’s your toothbrush looking

these days? Even if you can’t see it with a naked eye, experts say it may be saturated(使饱和)with millions of toilet

germs!

Dr. Charles Oerba, a germ expert, is amicrobiology professor at the University of Arizona. He says there are

approximately 3 million bacteria per square inch in most toilet bowls, and every time you flush it without closing

the lid, those millions of bacteria droplets spray into the air as far as twenty feet away and dirty everything in their

path. And a common victim is your poor toothbrush, usually, left out on the bathroom sink, right?

So, what do we do? Dr. Gerba says it’s easy. Close the toilet lid before you flush—that’ll greatly cut downthe

germs, which will otherwise float in the air. And wash your toothbrush every few days in mouthwash or peroxide

to get rid of any germs hiding in it. You can even put it through the dishwasher to sanitize(消毒)it. And always

store your toothbrush in a closed cabinet.

Here’s one more tip from Dr. Gerba, who says our kitchen sink is probably dirtier than our toilet. “If an alien

came from space and studied the bacterial counts, he probably would conclude he should wash his hands in your

toilet and go to the bathroom in your sink.” He says that’s because the kitchen sink is a great place where E. coli(大肠杆菌)to live and grow since it’s wet and damp. Bacteria feed on the food that people put down the drain

or—that’s left on dishes in the sink. To reset your sink’s bacteria count back to zero, you’d better regularly wash it

with hot water and sanitize yoursink with special chemicals. In fact, you may want to do it every day or before

preparing dinner.
