Will there be an outbreak of bird flu that threatens humans? Many experts disagree on when or whether a human pandemic (大流行病) will occur, but do say there is a chance that the virus could mutate(变异), leading to widespread infection.1.Here’s what you need to know to help keep yourself healthy.
Stock up on food, water and household supplies. If there is a bird flu pandemic, you'll want to minimize your chance of catching it by staying indoors; you might even be required to stay home if the government asks that people remain in quarantine (隔离期). You’d better stock up today on at least 2-week worth of essentials such as water, food, emergency and medical supplies. 2.
Have an outbreak plan. It may feel odd or uncomfortable to talk to family members and loved ones about the worst-case pandemic scenario. But if that scenario strikes, you’ll all be much better off if you have a plan decided on and ready. 3. Figure out how you would care for them and what your first response and responsibilities would be; this is an especially important conversation to have with those with special care needs.
4. Things like keeping a balanced diet, exercising regularly and getting sufficient rest can help keep you healthy in an outbreak and also keep you from catching the common cold. Particularly in a flu outbreak situation, it will be important to wash our hands with soap and water for at least 20 seconds. Be diligent about covering coughs and sneezes with tissues.
Moreover, know your essential health information such as blood type, allergies, and past or current medical conditions. Make a list of that essential information for all the members of your family. 5. And do make sure everyone in your household knows where to find it.
A.Work out regularly to stay slim.
B.Pick up the habits of healthy behavior.
C.It is wise to keep it somewhere safe and visible.
D.It’s important to ask yourself these questions before a pandemic occurs.
E.Talk with your friends and family about how you’d respond to an epidemic.
F.In that case, the best thing you can do right now is to prepare for that possibility.
G.That will help you get through an extended time at home if an outbreak happens.
Just how much does the Constitution(宪法) protect your digital data? The Supreme Court will now consider whether police can search the contents of a mobile phone without a warrant (授权令) if the phone is on or around a person during an arrest.
California has asked the justices to restore the practice that the police may search through the contents of suspects’ smartphones at the time of their arrest. It is hard, the state says, for judges to assess the implications of new and rapidly changing technologies .
The justices would be careless if they followed California's advice. They should start by rejecting California’s weak argument that exploring the contents of a smart phone is similar to say, going through a suspect's wallet. The court has ruled that police don't offend against the Fourth Amendment(修正案) when they go through the wallet of an arrestee without a warrant. In fact, exploring one's smartphone is more like entering his or her home. A smartphone may contain an arrestee's reading history, financial history, medical history and comprehensive records of recent correspondence.
Americans should take steps to protect their own digital privacy and should avoid putting important information in smartphones. But keeping sensitive information on these devices is increasingly a requirement of normal life. Citizens still have a right to expect private documents to remain private and protected by the Constitution's prohibition on unreasonable searches.
In many cases, it would not be very difficult for authorities to obtain a warrant to search through phone contents. They could still trump(打出王牌) the Fourth Amendment protections when facing severe and dangerous circumstances, such as the threat of immediate harm, and they could take reasonable measures to ensure that phone data are not deleted or altered while a warrant is on the way. The justices, though, may want to allow room for police to cite situations where they are entitled to more flexibility.
But the justices should not swallow California's argument whole. New technology sometimes demands fresh applications of the Constitution's protections. Orin Kerr, a law professor, compares the explosion and accessibility of digital information in the 21st century with the establishment of automobile use as a digital necessity of life in the 20th. At that time, the justices had to explain new rules for the new personal domain(领域) of cars. Similarly, the justices must sort out how the Fourth Amendment of the Constitution applies to digital information now.
1.The author’s attitude toward California’s argument is _____________.
A.skeptical B.tolerant
C.indifferent D.disapproving
2.The author believes that exploring one's phone content is comparable to_____________.
A.getting into one's residence B.handing one's historical records
C.scanning one's correspondences D.going through one's wallet
3.In paragraph 4 and 5, the author shows his concern that_____________.
A.principles are hard to be clearly expressed
B.citizens' privacy is not effectively protected
C.phones are used to store sensitive information
D.the court is giving police less room for action
4.Orin Kerr's comparison is quoted to indicate that_____________.
A.the Constitution should be implemented flexibly
B.Principles of the Constitution should never be changed
C.New technology requires reinterpretation of the Constitution
D.California's argument violates principles of the Constitution
With self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the final leg of the delivery process, from the store or local distribution center to the customer. The latest to join the trend is e-commerce giant Amazon. Following a successful eight-month test run in Snohomish County, Washington, the company’s Scout robots have been making the rounds of Irvine, California, since August 6, 2019.
The six-wheeled Scout is about the size of a large cooler with the capacity to carry small or medium-sized packages. The battery-powered vehicle, which moves at a regular walking pace, has been programmed to avoid pedestrians, animals, and unexpected obstacles, such as garbage cans. Its powerful sensors can also detect the movement of a car backing out of a driveway.
To accelerate Scout’s development and bring it nationwide sooner, the company has created several detailed virtual maps of American suburbs and conducted trial deliveries to homes there.
Though Amazon has not shown how Scout ensures the delivery is picked up by the right person, it most likely requires the customers to apply a unique code, texted to them prior to the delivery, to unlock the store box. Also unclear is the number of deliveries Scout can complete before its battery needs to be recharged. Though the initial tests are being conducted with a human for company, the robot will be autonomous in the future. Its location, however, will be tracked at all times—if someone attempts to steal Scout, Amazon employees will be instantly sensed.
However, the eco-friendly robots are unable to climb stairs or open gates, which means that they can only reach consumers who live on the ground level. Additionally, the robots are unable to leave packages at the front door if the customers are not home. Whether these problems get resolved remains to be seen. For now, it appears that humans will still be needed to achieve the ever-growing demand for home and office deliveries.
1.Which of the following descriptions about Scout is right?
A.They can be powered themselves. B.They are strong enough to carry big things.
C.They can run with their six wheels. D.They can avoid obstacles ahead.
2.What about Scout is still confusing to common people?
A.How many deliveries it can do on a full charge. B.Whether it can climb stairs or open gates.
C.How it recognizes the right owner of the things. D.How long it will take to get it fully charged.
3.What does the underlined phrase “prior to” in paragraph 4 mean?
A.due to B.after C.in front of D.before
4.What is the author’s opinion about delivery robots according to the last paragraph?
A.They are not easily available. B.They have some limitations.
C.They will replace humans soon. D.They won’t be well accepted.
I remember the day when I first learned to ride a bike. It was a frightening, yet fun experience. My granddad was the one who taught me and he helped me when I got hurt. The first time I got on a bike, I had no idea what I was doing, and just about everything went wrong. My granddad told me to just put my feet on the pedals and start pedaling (骑自行车). He also told me he would hold onto the back of the bike the whole time, yet he didn’t.
As soon as I started trying to balance myself, he let go. I happened to look back just then. I was scared, to death that I was going to fall and hurt myself. When I was scared, my mind went blank from pedaling, and I just wanted off. I forgot how to use the brakes (车闸) and fell right off the bike. My granddad kept encouraging me to get up and try again, and after about 15 minutes, 1 finally stopped crying, got up and tried again.
As soon as I started pedaling again, my pants got caught in the chain, and I fell flat on my face and hit my nose. Since that happened t my granddad decided to call it a day and try again the next morning. The next morning I woke up bright and early, and was very eager to try to ride my bike. My nose felt better, so I wasn’t that afraid of falling anymore.
Though I knew there were a lot of difficulties on the way to mastering the skills in riding a bike, I believed I could do well with my granddad’s help. After all, riding a bike was what I wanted to do eagerly.

阅读下面短文, 根据所给情节进行续写,使之构成一个完整的故事。
On Friday evening, Emmett and I went to a movie as scheduled. After purchasing the tickets and drinks, we entered the cinema with delight beforehand, waiting for the beginning of the movie.
When I got up in the middle of the movie, Emmett whispered, “ Carter, where are you going?” “I forgot to call my mom to tell her what time to pick us up.” I whispered back, leaving my jacket on the seat.
I squeezed past the people in my row, trying not to step on any feet while still watching the screen. I didn’t want to miss a thing. Balfour, the good guy in the movie, was trapped in an underground cave.
When I came back, Balfour’s flashlight almost went out. An enormous snake was moving toward him, twisting its body. Balfour struggled to loosen the chains around his hands and feet to reach his magic cape (魔法斗篷). With the cape around him, he could completely disappear.
I crawled (缓慢行进) back across eight people (I counted on the way out), never taking my eyes off the screen. I sat down in my seat slowly, then picked up my drink, and swallowed it quickly. But suddenly my brain said, “That’s not coke. That’s lemonade.” I looked down at the cup, just as the girl next to me shouted, “He drank my lemonade!”
“Shhhh!” the people around us said, making quiet complaints.
“Where’s Emmett?” I asked, as if the girl had hidden him under her seat.
“Carter, down here,” Emmett answered in a low voice. He was two rows ahead of me. I was in the wrong row! Everyone was turning around to look at me.
“Here,” I said, handing the girl her drink.
“Eww,” she said. “You have had a drink of it, so you owe me a lemonade.”
“Shhhh!” everyone said again.
“OK, OK,” I said, starting my crawl across eight sets of feet again. Everybody were complaining as I inched out.
“Don’t come back,” the boy on the end said.
