Electric Shocks Can Be Fatal
Government statistics recently showed that in theUK, more than 3,000 people a year experience electric shocks in their homes. A smaller number of people are killed after they touch the power lines outside their homes. Electric shocks can cause a person's heart or breath to stop and are potentially fatal. It is essential for people to learn basic techniques to deal with such emergencies.
What to do?
● If you are the first person to reach someone who has an electric shock, don't touch him or her!
● If the victim is still holding the appliance that gives him or her the shock (e.g. a hair dryer), unplug it or turn off the power at its source.Under no circumstances can you try to move the appliance with your hands!
● Ifyou can't turn off the power, use a piece of wood, like a broom handle or a chair, to separate the victim from the appliance or the power source. You may even be able to do this with a folded newspaper.
● The victim must remain lying down. If he or she isunconscious, the victim should be placed on his or her side. But he or she should not be moved if there is a possibility of neck or spine injuries unless it is ly necessary.
● It is essential to maintain the victim's body heat, so make sure you cover him or her with a blanket before you do anything else. If the victim is not breathing, apply mouth-to-mouth resuscitation (人工呼吸). Keep the victim's head low until professional help arrives.
● If the electric shock has been caused by an external power line, the dangers to the victim and to anybody providing first aid are much greater.

Last year, 138,000San Franciscoresidents used Airbnb, a popular app designed to connect home renters and travelers. It’s a striking number for a city with a population of about 850,000, and it was enough for Airbnb to win a major victory in local elections, asSan Franciscovoters struck down a debatable rule that would have placed time restrictions and other regulations on short-term rental services.
The company fiercely opposed the measure, Proposition F, with a nearly $10 million advertising campaign. It also contacted its San Franciscan users with messages urging them to vote against Proposition F.
Most people think of Airbnb as a kind of couch-surfing app. The service works for one-night stays on road trips and longer stays in cities, and it often has more competitive pricing than hotels. It’s a textbook example of the “sharing economy”, but not everyone is a fan.
The app has had unintended consequences inSan Francisco. As the San Francisco Chronicle reported last year, a significant amount of renting on Airbnb is not in line with the company’s image: middle-class families putting up a spare room to help make ends meet. Some users have taken advantage of the service, using it to turn their multiple properties into vacation rentals or even full-time rentals. Backers of Proposition F argued that this trend takes spaces off the conventional, better-regulated housing market and contributes to rising costs.
“The fact is, widespread abuse of short-term rentals is taking much needed housing off the market and harming our neighborhoods,” said ShareBetter SF, a group that supported Proposition F. Hotel unions have protested the company’s practices inSan Franciscoand other cities, saying that it creates an illegal hotel system.
San Franciscois in the middle of a long-term, deeply rooted housing crisis that has seen the cost of living explode. Actually, explode is a generous term. The average monthly rent for an apartment is around $4, 000. Located on a narrow outcropping of land overlooking the bay,San Franciscosimply doesn’t have enough space to accommodate the massive inflow of young, high-salaried tech employees flocking toSilicon Valley.
As the Los Angeles Times reported, someSan Franciscoresidents supported the measure simply because it
seemed like a way to check a big corporation. Opponents of Proposition F countered that the housing crisis runs much deeper, and that passing the rule would have discouraged a popular service while doing little to solve the city’s existing problems.
4. The intention of Proposition F is to ________.
A. place time limits in local election.
B. set limits on short-term rental.
C. strike down a controversial rule.
D. urge users to vote against Airbnb.
5. What is the negative consequence of Airbnb onSan Francisco?
A. It shrinks the living space of middle-class families.
B. Users are taken advantage of by the service financially.
C. It makes the house market more competitive.
D. It indirectly leads to high house rental price.
6. The housing crisis inSan Franciscoresults from ________.
A. explosion of the living cost
B. its geographic characteristics
C. generosity of local enterprises
D. inflow of migrant population
7. Theauthor’s attitude toward Proposition F is ________.
A. objective
B. supportive
C. negative
D. indifferent
C
Scott and Daniel Harry are enjoying everyday tasks like shopping and washing for the first time following their move to an accommodation (住宿) support house in Kurwongbah, north of Brisbane last year.
Disability Services Queensland’s Strengthening Non-Government Organisations project provided an accommodation support model that would enable residents (居住者) like Daniel and Scott to live more independently.
The house is just one of many accommodation support services funded (资助)through the project. The five-bedroom house provides 24-hour care for up to four individuals with complex needs, including medical support. Care and staffing levels are varied and flexible, depending on each resident’s requirements.
Scott and Daniel, who have a severe form of Duchenne Muscular Dystrophy, require 24-hour support in all activities of daily living. Before they moved to the house, they lived with their family. Scott says living at home was difficult as it placed a physical and emotional strain(负担) on their parents who had to wake them several times each night to reposition them or place them on breathing machines.
“We were heavyhearted,” says Scott, who is planning to write a book about his life experiences. “But our parents now have a lot moretime for themselves. We now manage ourselves on a day-to-day basis.”
Daniel is an enthusiastic gardener, taking care of his own vegetable garden. The men share the house with one other young man, and they go to rugby league games, meeting up with friends.
Leeding Care Australia provides the care service at Kurwongbah. Manager Lee Garniss says setting up the facilities (设施) has not been without its challenges.
“It is an unconventional model of care,” Lee says. “The home is Scott and Daniel’s home, however it is also a workplace for their support staff. Balancing these two requirements has been a challenge for all.”
“We have experienced a bit of a learning phase over the last twelve months. However, by working as a team we try our best to meet the needs of both residents and staff and I think we have achieved the right balance.”
8. What do we know about the house Scott and Daniel live in now?
A. It was built by their parents.
B. It can accommodate four residents.
C. It belongs to a governmental project.
D. It’s located in the center of Brisbane.
9. Why did Scott and Daniel’s parents wake up frequently at night?
A. To help them do exercise.
B. They were making a lot of noise.
C. To check on their breathing.
D. They were under emotional pressure.
10. How did Scott feel while living with his parents?
A. A bit guilty.
B. Quite happy.
C. Very proud.
D. Slightly angry.
11. What was a challenge while setting up the facilities?
A. Lack of fund.
B. No workplace.
C. Inexperienced staff members.
D. Satisfying both staff and residents’ needs.
D
This year researchers expect the world to snap 1.35 trillion photographs, or about 3.7 billion per day. All those pixels (像素) take up a lot of room if they are stored on personal computers or s phones, which is one reason why many people store their images in the cloud. But unlike a hard on drive which can be encrypted to protect its data, cloud storage users have to trust that a tech platform will keep their private pictures safe. Now a team of Columbia University computer scientists has developed a tool to encrypt (加密) images stored on many
popular cloud services while allowing authorized users to browse and display their photographs as usual.
Malicious (恶意的) attempts to access or leak cloud-based photographs can expose personal information. In November 2019, for example, a bug in the popular photograph storage app Google Photos mistakenly shared some users' private videos with strangers. Security experts also worry about employees at cloud storage companies on purpose accessing users' images.
So the Columbia researchers came up with a system called Easy Secure Photos (ESP), which they presented at a recent conference. “We wanted to see if we could make it possible to encrypt data while using existing services,” says computer scientist Jason Nieh, one of the developers of ESP. “Everyone wants to stay with Google Photos and not have to register on a new encrypted-image cloud storage service.”
To overcome this problem, they created a tool that preserves blocks of pixels but moves them around to effectively hide the photograph. First, ESP's algorithm (算法) divides a photograph into three separate files, each one containing the image's red, green or blue color1 data. Then the system hides the pixel blocks around among these three files (allowing a block from the red file, for instance, to hide out in the green or blue ones). But the program does nothing within the pixel blocks, where all the image processing happens. As a result, the files remain unchanged images but end up looking like grainy black-and-white ones to anyone who accesses them without the decryption (解密) key.
12. What's probably the main purpose for people to store images in the cloud?
A. To save storage room.
B. To make photos beautiful.
C. To try a new storage way.
D. To keep their privacy safe.
13. Why might employees in cloud storage companies be distrusted by experts?
A. They sell users' passwords.
B. They have invented new tools.
C. They often let out personal information.
D. They may steal a glance at users' images.
14. What's the advantage of ESP?
A. It can provide clear images.
B. It can decrease the upload time.
C. It can classify images automatically.
D. It can encrypt data on the original platform.
15. What does paragraph 4 mainly talk about?
A. Method of decryption.
B. Image-processing technique.
C. Separate files of images.
D. Data analysisof color1 s.

One year ago, I was in great trouble. I work hard at English and devoted all my spare time to practise it. But I failed to pass the mid-term exam, which made me great disappointed. So I asked my grandpa for suggestions when I got to home. Hear what I told him, he said, “Exam results are sometime unexpected . You can't judge your progress by one examination.” He encouraged myself to work hard for long time to check my results. I took my grandpa's advices.

Harry was afraid of thewind, I blew of hishat.I whistled under his door. It made the iron fence murmur scary music.

On windy days Harry sod at his window and watched Antony riding his bike, whose hair flew in the wind. He watched his friend playing cheerfully in the wind, wishing he weren'tafraid.
One day Antony came to Harry's house to play. “Look at my glider(滑翔机),” said Antony. “It does tricks and loop-de-loops when Iflyit outside in the wind.” “Nice,” said Harry.
When clouds rolled in, the tree in front of Harry's house swung. A garbage can top clattered(发出撞击声) down the street. Antony couldn't wait to fly the glider outside and invited Harry to play together, but he refused.
Harry staved inside and played with his construction set. He pictured launching the glider with Antony. But when he imagined the windblowingagainst his face and blowing off his hat, he shivered.
Harry drew pictures of Antony's glider lifting with the wind. Gradually, hearing the happylaughterand shouts of more children outside, he felt sad to be in his room while everyone else was there.
Harry began to make akite. He took two sticks from his craft bin and crossed them. He tied them together and made a diamond shape with four more sticks.
