If you’re anything like the average American, you probably check your smartphone more than50 times per day as a 2018 study found. 1. In fact, The University of Arizona found back in2012 that cell phones carry 10 times more bacteria than a toilet seat, largely because toilet seats are typically cleaned more frequently while personal electronics are largely overlooked.
As the novel corona virus (新型冠状病毒) continues to spread, the Centers for Disease Control and Prevention and the World Health Organization are advising the general public to wash hands often and disinfect (消毒) frequently touched objects and surfaces. 2.
But cleaning your phone can be tricky, considering many of the standard cleaning products you’d typically use for disinfection could potentially damage your mobile device. You may want to wipe down your phones screen with some rubbing alcohol or a disinfectant wipe. 3. These phones have a coating on then to prevent oil or grease from your hand from sticking on the phone. Using alcohol or those types of everyday solutions directly on a phone, on its glass can harm it. 4.
That lines up with the advice Apple and Samsung offer which warn not to use cleaning products. 5. If you need to disinfect your smartphone, consider looking into a UV light to kill the bacteria.
A.Avoid using alcohol.
B.But in doing so, you risk damaging your devices screen.
C.That means keeping your phone clean is important as well.
D.You should still be cautious when exposing them to liquids.
E.Instead use a micro fiber cloth and dampen it lightly with soap and water.
F.And each time you do, your mobile device picks up more bacteria from your hands.
G.Both companies say wiping your phone down with a soft cloth is the best way to clean it.
It might be hard at first glance to see what things like toothbrushes, tires, cigarettes, and shoes have in common. But look closer and you’ll find that, like so many objects in our daily lives, they’re often made to a greater or lesser degree of the magic stuff (东西): plastic.
That stuff is now a planetary problem. Sometimes, because the plastic is mixed with other materials — including other plastics, such as in shoes — it’s difficult or impossible to recycle. In many places, recycling or burying in a landfill isn’t an option, not to mention all the waste that ends up in rivers and oceans. And so, more often than not, after a short useful life, plastic objects enter what’s likely to be a centuries-long afterlife as rubbish.
They’re thrown into rivers and washed into the sea. They break down into tiny bits called micro plastics. Sea animals big and small eat those pieces. Some pieces get mixed in with sea salt and we wind up eating them, with uncertain effects. We breathe in even smaller pieces called nano plastics: Scientists recently discovered them on remote mountaintops and even in the Arctic, where they are carried by winds and mixed with rain and snow.
The magic stuff has now become the stuff of nightmares.
Increasingly the challenge is to have the former without the latter. “Reduce, reuse, and recycle” has been the environmentalists’ answer for half a century. Businesses that sell plastic products or packaging, however, have little motivation to encourage reducing or reusing, and recycling — once thought a cure-all — can be complex and expensive. But with plastic pollution now a global problem, the stakes (风险) are raised, and so is public awareness.
Plastic waste has started to worry us. Business owners are creating new options for avoiding it. The point is not to demonize（妖魔化）things that were invented for good reason and with good intentions; the point is to find a way to have our plastic and not eat it too.
1.Which of the following can best describe plastic in our life according to Paragraph 1?
A.Old-fashioned B.Widely-used
C.Harmful D.Useless
2.What can we infer about the solution to plastic pollution in the last 50 years?
A.It hasn’t worked properly.
B.It has been totally ignored.
C.It hasn’t gained support from the public.
D.It has encouraged the businesses to recycle.
3.Which of the following will the author agree with to solve plastic problem?
A.A ban on plastic production.
B.A law punishing plastic littering.
C.An alternative material replacing plastic.
D.A new method of using without pollution.
4.Where is the text most likely from?
A.A magazine. B.A guidebook.
C.A novel. D.A diary.
Dyslexia is a problem that interferes (干扰) with the ability to recognize words and connect sounds with letters when people read. People with this learning disorder may also have problems when they write. Dyslexia is not related to eyesight or intelligence. The problem involves (涉及)areas of the brain that process language.
Brain scientists are studying whether they can predict which young children may struggle with reading, in order to provide early help. John Gabrieli is leading a study of five-year-olds in about twenty schools. He says, “We partner with schools that have kindergartens. What we do is, for all the children whose parents permit them to participate, we give them a brief set of paper-and-pencil tests to look at which children appear to be at some risk for struggling to read.
So far, fifty of the kindergartners have been examined in a machine that shows brain activity. The scanner uses a high-energy magnetic (有磁性的) field and radio waves to “look” inside the body. Written tests which are often used in previous studies are not always able to identify dyslexia or other problems. Professor Gabrieli says, “Brain scans may offer a more scientific way to identify problems.
And with reading problems, early identification is important. Reading problems are not usually identified until a child is in the third or fourth grade. The later children are recognized as poor readers, the less these interventions can help. And, as Professor Gabrieli points out, poor reading can make education a struggle. Reading is everything. Even math and science require one to read textbooks.
1.What do we know about Dyslexia?
A.It results in poor eyesight.
B.It is related to brain activity.
C.It only causes reading difficulty.
D.It has an influence on intelligence.
2.What does the underlined word “interventions” in the last paragraph probably mean?
A.Approaches. B.Researches.
C.Instructions. D.Treatments.
3.How is Professor Gabrieli’s study different from early ones?
A.It is scientifically based.
B.It focuses on written tests.
C.It examines children’s brains.
D.It needs parents’ participation.
4.What can be a suitable title for the text?
A.Dyslexia – a Learning Disorder Involving Intelligence
B.Dyslexia – a Problem Relating to Kindergartners
C.A Way Identifying Dyslexia at an Early Stage
D.A Machine Showing Brain Development
