高三英语单项填空中等难度题查看答案及解析

You want a smart phone， but just how smart do you want it？ How about one that can read your mind？ Well， that phone may well be on its way...

Justin Rattner， chief researcher at Intel， says that technology has developed to the point that “context-aware computing (情景感知计算)”， an idea that’s been around for twenty years， is becoming more of a reality.

That could lead to a phone that acts as a mind reader in your pocket. But rather than simply collect secrets about you， the device could do things with that information， such as predict what you might do next and make suggestions.

Rattner gave a few examples during his speech at Intel’s developer conference in San Francisco recently.

Among them is a software that Intel worked on with Fodor’s Travel， a traveling website. It learns what types of foods you like to eat and what types of places you like to visit， based on searches you type into the phone or places you searched using GPS (全球定位系统). The software makes similar recommendations when you visit a new city.

Tech companies are already working to predict what people want. Search engine Google， movie-rental service Netflix， and online radio service Pandora try to guess what people want even before they know they want it.

Putting those types of functions together with the other information that phones collect about people could pave the way for even more helpful mobile phones， Rattner said.

A challenge is training computers to look at data from “hard sensors (传感器)” (which measure place， movement， temperature and the like) and combining those findings with data from “soft sensors” (such as calendar appointments and Web browsing history).

For example， your phone could tell that you have just left school and seem to be on your way home—a location it might know from your address book. It could then tell you the best route around traffic.

Rattner added that researchers are even making steps toward the final goal—a computer understanding of thoughts.

It’s hard for elderly people to see ______ convenience a smart phone can bring to us.

A．what　　　 B．which　　 C．whose　　 D．how

高三英语单项填空中等难度题查看答案及解析

You can’t see it with your own eyes，but your smart-phone is likely to be covered with bacteria- perhaps even more so than your toilet seat. That's a lot of dangerous microbes（微生物）floating around, and yes, it is terribly dirty.

In this age of global travel and trade, it’s more important than ever to cut down on possible routes of infection and to stop bacteria and viruses spreading from person to person. Part of that means making sure your phone isn’t sending anything more than data.

And besides the potential health risks of a dirty phone, there's also the simple annoyance of looking at a screen that’s covered in fingerprints and other oily spots that are part of life with a smart-phone.

In short, you’ve got plenty of reasons to regularly give your phone a thorough clean. Not just during a pandemic（大流行病），either-we should be thinking about keeping our phones bacteria free all the time, says microbiologist Paul Turner, a professor at Yale University.

After all, we touch our phones all the time and many of us are relatively careless about cleaning them. “It sets the stage for kind of concern,” Turner says. “People could be handling phones and picking up any bacteria or virus that can attach to a surface and survive for a period of time.”

Take SARS-CoV-2, the corona- virus（冠状病毒）that causes the COVID-19, for example. Scientists are still trying to get solid evidence, but early research suggests that it can survive on plastic or stainless steel（不锈钢）surfaces for two or three days. That means you could be washing your hands perfectly well, but immediately picking the virus up again as soon as you reach for your phone.

You could be doing everything right（like washing your hands and staying away from people），but

if there’s a contaminated surface in your home or your pocket, you could expose yourself to the virus anyway, Turner says.

1.Why does the author mention the toilet seat?

A.To draw a vivid picture of a dirty phone.

B.To show how dirty a toilet seat is.

C.To add some background information.

D.To introduce a topic for discussion.

2.What can we learn in Paragraph 6?

A.Simply washing our hands is not enough.

B.Scientists have got solid evidence of the COVID-19.

C.The corona-virus can survive on smooth surfaces for 2 or 3 weeks.

D.The author suggests washing our hands before using our phones.

3.What do the underlined words “contaminated surface” refer to in the last paragraph?

A.A stainless steel. B.A deadly virus.

C.A clean phone. D.An infectious phone.

4.What is the main idea of the text?

A.You may get infected with your dirty phone.

B.You are supposed to wash your hands.

C.You’d better clean your dirty phone.

D.You’d better throw away your dirty phone.
