【题目】 Curiosity is what drives us to keep learning, keep trying, keep pushing forward. But how does one generate (产生) curiosity, in oneself or others? George Loewenstein, a professor of psychology at Carnegie Mellon University, offered an answer in the classic1994 paper, “The Psychology of Curiosity.”

Curiosity arises, Loewenstein wrote, “when attention becomes focused on a gap in one's knowledge. Such information gaps produce the feeling of deprivation (匮乏) labeled curiosity. The curious individual is motivated to obtain the missing information to reduce the feeling of deprivation.” Loewenstein's theory helps explain why curiosity is such a force: it's not only a mental state but also an emotion, a powerful feeling that drives us forward.

Scientist Daniel Willingham notes that teachers are often “so eager to get to the answer that we do not devote enough time to developing the question.” Yet it's the question that stimulates (刺激) curiosity; being told an answer stops curiosity before it can even get going.

In his 1994 paper, George Loewenstein noted that curiosity requires some basic knowledge. We're not curious about something we know absolutely nothing about. But as soon as we know even a little bit, our curiosity is aroused and we want to learn more. In fact, research shows that curiosity increases with knowledge: the more we know, the more we want to know. To get this process started, Loewenstein suggests, take steps with some interesting but incomplete information.

Language teachers have long used communication in exercises that open an information gap and then require learners to communicate with each other in order to fill it. For example, one student might be given a series of pictures for the beginning of the story, while the student's partner is given a series of pictures showing how that same story ends. Only by speaking with each other (in the foreign language they are learning, of course) can the students fill in each others' information gaps.

1When one notices a gap in his knowledge, he .

A.desires to fill it

B.tends to be afraid

C.might get tired and sad

D.will become focused on his learning

2What does Daniel Willingham imply in the article?

B.Teachers should be eager to get to the answer.

C.have some related informationD.are given incomplete information

4What is the article mainly about?

A.Why students hate school.

【题目】As is tradition, technology companies from around the world have flocked to Las Vegas for the annual Consumer Electronics Show. There are thousands of eye-catching items to swoon over, whether you’re a nerd or not. Here are a few of the most interesting, exciting and possibly life-changing products seen at the show, which runs from Tuesday to Friday.

Item 1

You thought your curved TV was cool? The LG Signature OLED TV R is a 65-inch 4K TV that is, unlike your lame and rigid screen, rollable, and can retract(收回) into its base when you’re not enjoying it. While you can control it using either Google Assistant or Amazon Alexa, the TV R also supports Apple’s AirPlay 2 and HomeKit.

Item 2

Gaming laptops aren’t new, but they usually lack power compared to their beefier desktop counterparts. Nvidia’s latest announcement changes that, and brings the desktop-class power found in its RTX line of graphics cards to laptops. More than 40 laptop models will turn up by the end of the month with RTX graphics cards inside, which can produce more realistic graphics and boost performance for the most gamers.

Item 3

If sleeping is harder than it should be, the Dreem band might be able to help you figure out what you’re doing wrong. The Dreem band is a fabric-covered headband that wraps around your head and uses a combination of sensors like the ones in your Apple Watch to detect various biometrics like your heart rate and respiration activity. It also uses bone conduction to communicate audio cues to you privately.

Item 4

Samsung’s shown off its Micro LED technology in the past, using it to build The Wall, a 146-inch TV. The company’s now showing off a smaller Micro LED TV. Using Samsung’s Micro LED panels, you can create a variety of display sizes supporting different aspect ratios, going from an ultra-wide 21:9 screen to a perfectly square 1:1 display without losing image quality.

1If one likes doing things by himself, which of the items suits him best?

A. Item 1. B. Item 2.

C. Item 3. D. Item 4.

2Which of the following technologies appeared for the first time in the show?

C. The Dreem band’s detect your heart rate

D. Samsung’s Micro LED technology making a 146-inch TV possible
