3 . Do you have any c_______to make about the cause of the disaster?(根据首字母单词拼写)

4 . People who are a________ to computer games should break this habit. (根据首字母单词拼写)

5 . The brain has a powerful ability to remember and connect events separated in time. And now, in that new study in mice published in Neuron, scientists have cast light on how the brain can form lasting links.

The hippocampus (海马体)—a small, seahorse-shaped region buried deep in the brain—is an important headquarters for learning and memory. “The traditional view has been that cells in the hippocampus keep up a level of continuous activity to associate two events separated by tens of seconds.” said Dr. Ahmed, co-first author of the study. “Turning these cells off would thus disrupt learning.”

To test this view, the researchers imaged parts of the hippocampus of mice as the animals were exposed to two different stimuli(刺激物): a sound followed by a small but unpleasant puff of air. A fifteen-second delay separated the two events. The scientists repeated this experiment across several trials. Over time, the mice learned to associate the sound with the soon-to-follow puff of air. Using advanced microscopy, they recorded the activity of thousands of neurons (神经元), a type of brain cell, in the animals’ hippocampus in each trial for many days.

“We expected to see continuous neural activity that lasted during the fifteen-second gap, an indication of the hippocampus at work linking the sound and the air puff,” said Stefano Fusi, PhD. “But when we began to analyze the data, we saw no such activity.” Instead, the neural activity was sparse. Only a small number of neurons worked, and they did so seemingly at random (随意的).

For further understanding, they had to shift the way they analyzed data and use tools designed to make sense of random processes. Finally, the researchers discovered a complex pattern: a style of mental computing that seems to be a remarkably efficient way that neurons store information.

“We were happy to see that the brain doesn’t maintain ongoing activity over all these seconds because that’s not the most efficient way to store information,” said Dr. Ahmed. “The brain seems to have a more efficient way to build this bridge.”

In addition to helping to map the circuitry (神经回路) involved in associative learning, these findings also provide a starting point to more deeply explore disorders, such as panic and post-traumatic stress disorder.

1. What can we learn about the hippocampus?

A．It helps connect events separated in places.

B．It is involved in the visual area of the brain.

C．It is a kind of cell buried deep in the brain.

D．It is a brain region crucial for memory.

2. According to the passage, the traditional view is that ______.

A．animals have trouble learning to associate two events

B．associations of events require continuous neural activity

C．a 15-second delay is enough to separate two events

D．disruption of learning turn the activities of cells off

3. The new study in mice indicates that ______.

A．continuous activity happens as expected

B．no neurons stay active at intervals of 15 seconds

C．a complex pattern helps the brain learn associations

D．neuronal information is stored in well-designed tools

4. From the last two paragraphs, we can infer that the findings ______.

A．inspire deeper explorations of disorders

B．build a bridge between different parts of the brain

C．provide evidence for brain’s ongoing activity

D．help map some aspects of a person’s experience

6 . Multiple Tour Dates in 2020 & 2021

This is the most exciting tour to Egypt ever offered! Led by the world’s most famous archaeologist, Dr. Zahi Hawass, The Royal Tour to Egypt provides unparalleled access to the wonders of Ancient Egypt.

Visit the Giza Pyramids and Luxor Temple outside of regular opening hours for a more intimate and crowd-free experience. Have a once-in-a-lifetime chance to stand between the paws of the Great Sphinx (狮身人面像) instead of seeing it from the viewing platform. You will hear secrets never told before and spend time in the esteemed company of Dr. Mostafa Waziri，Egypt’s Head of Antiquities. Former First Lady，Mrs. Jehan Sadat，will host you in the living place of Egypt’s late president Anwar Sadat—an experience normally reserved for royalty and heads of state.

7 . The next time a giant Big Mac or Coke flashes into your mind when you’re walking home from the pub, you may not simply have the snacks.

A British hi-tech company has created a new advertising system that uses lasers (激光) to project images up to 200 metres tall from the sides of tall buildings, enabling advertisers to reach people from virtual billboards in the sky. Passers-by will see each image for only between one tenth and quarter of a second, as their eyes catch the light from certain angles.

Advertising agencies and big businesses have already signalled their interest, but Skyline campaigners have branded the technology “greedy” and said that it could fill our skies with showy and tasteless brands.

The Echo system uses a high laser projector to bounce light off a narrow reflective strip fixed to the side of a building, visible up to 1km away. This creates large-scale images that are captured briefly in the viewer’s eye as a result of the “persistence of vision” effect: the same effect that leaves an imprint (印记) of a light source on your vision after you’ve turned away.

Daniel Siden, the technology’s inventor, explained: People often think this could be subversive, but it’s actually less invasive and more fun than traditional advertising. Mr.Siden said that the system was safe because of the distance between the projector and passers-by. And images would be above the line of sight of drivers and cyclists and below the field of vision of airline pilot. The images have been tested and shown not to cause epileptic seizures (癫痫发作).

Because it uses only one strip of reflected light, the system needs a small amount of the power, about one-twentieth of a standard 96-sheet digital outdoor display for an image of the same height.

Still, some Skyline campaigners dislike the technology and believe it delivers subliminal advertising (隐形广告). Barbara Weiss of the Skyline Campaign, said: “It’s actually offensive. London’s latest tall buildings are not particularly well-built or well designed, but unfortunately people are forced to look at them. Adding stupid advertising that’s invasive in its nature will only make it worse.”

1. Why does the writer use the example of Big Mac, Coke in paragraph 1?

A．Because he attempts to promote these products to potential consumers.

B．Because he wants to introduce a new advertising technology to readers.

C．Because he studies the association between products and images in advertising.

D．Because he tries to illustrate the effectiveness of flashing images of advertised goods.

2. Which of the following statements about the Echo system is true according to the passage?

A．Pedestrians can see the flashing images from specific angles.

B．It’s a new system developed by an advertising agency.

C．The image will no longer exist in vision after you’ve turned away.

D．The system consists of a laser projector, a reflective strip and a physical billboard.

3. The underlined word “subversive” in paragraph 5 probably means ________.

A．subconscious

B．damaging

C．harmless

D．imaginative

4. Which party is likely to set obstacles to the application of the Echo system?

A．Environmentalists worried about energy consumption.

B．Drivers, cyclists and pilots whose sight might be affected.

C．The Skyline Campaign regarding the technology as flashy.

D．The patients who suffer from epileptic seizures.
