阅读七选五分类练(一)——说明文
A
(2022·黄石高三模拟)It's a common practice to take off your shoes when you enter your home. Many do this to prevent dirt and bacteria from getting inside. __1__
Technically, yes. As you walk around outside, your shoes pick up bacteria, viruses and dirt. A 2017 study showed that more than 26 percent of the soles (鞋底) of shoes worn in homes contained Clostridium difficile, or C. diff, a common kind of bacteria that can cause deadly diseases.
But if that worries you, get this — the average person has more than 100 trillion microbes (微生物) in and on his body. __2__ And if your pets go outside, they're bringing in dirty stuff on their paws and fur. Thankfully, most of the bacteria on your body and in your home are harmless. So is the stuff on your shoes.
__3__ Take them off if you've got little kids crawling around on the floors, who may then put their fingers in their mouths. Disinfect your home if someone in your home is sensitive. And since pollen (花粉) can be transferred from shoes to floors, and especially carpets, kick off your shoes if someone at home has allergies.
__4__ Each of your feet has about 125,000 sweat glands (汗腺) on the sole, and any sweat on your feet can be transferred to carpets. Wet carpets, in turn,trap dirt.
In the end, the choice of whether or not to go shoeless is yours. __5__ But whether your shoes are on or off, you need to clean your home as often as possible.
A.But is that really an issue?
B.Sweat can also contain microbes.
C.Your home is covered in bacteria, too.
D.Despite this, other people think this is unnecessary.
E.Some people just like the feel of walking around in bare feet.
F.Still, there are some cases where it may make sense to remove your shoes.
G.If you're really determined to cut down on dirt, keep your slippers on rather than going barefoot.
