With self-driving vehicle technology rapidly advancing, many companies are turning to autonomous robots for the last mile of the delivery process, from the store 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 stay away from pedestrians, animals, and unexpected obstacles, like garbage cans. Its powerful sensors can also detect the movement of a car backing out of a driveway.

Though Amazon hasn’t revealed how Scout ensures the delivery is picked up by the right person, it most likely requires the customer to apply a unique code, texted to them before the delivery, to unlock the cargo bay. Also unclear is the number of deliveries Scout can complete before its battery needs recharging Though the initial tests are being conducted with a human in tow, 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 alerted.

While Amazon is focusing on home deliveries, food and grocery delivery company Postmates’ bug-eyed robots are currently making their rounds along the busy San Francisco streets. Also in test-mode, the robots can carry up to 50 pounds and travel 30 miles on a single battery charge.

Though the eco-friendly robots will help free our streets of bicycles, motor bikes, and large delivery trucks that typically ferry packages, they can t climb stairs or open gates, which means they can only reach consumers living the ground level. Additionally, the robots are unable to leave packages at the front door if the customers aren’t home. whether these issues get solved remains to be seen. For now, it appears that humans will still be needed to satisfy the ever-growing demand for home and office deliveries.

1.What is the right feature of the Scout robots?

A.They can be powered themselves. B.They know to avoid obstacles ahead.

C.They can run thanks to their six wheels. D.They’re big enough to carry heavy things.

2.What about Scout is still confusing to common people?

A.How long it will take to get it fully charged.

B.Why its cargo bay can open at the right time.

C.How it recognizes the right owner of the things.

D.How many deliveries it can do on a full charge.

3.What is the author’s opinion about delivery robots according to the last paragraph?

A.They are not easily available. B.They’ll replace humans soon.

C.They have some limitations. D.They won’t be well accepted.

4.What should be the best title for the text?

A.Improvements Are Being Made To Delivery robot Technology.

B.Amazon has Planned To Put A Creative Delivery Robot Into Use.

C.Eco-friendly delivery Robots Are Springing Up Around America.

D.Amazon’s delivery Robots May Soon Be Knocking At Your Door.

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 customer 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.What are many companies developing autonomous robots for?

A.Final tests. B.The so-called last mile.

C.Robots' safety. D.Delivery speed.

2.What can we infer about Scout from paragraph 2?

A.It looks like a cooler. B.It adjusts its speed accordingly.

C.Its sensors play a key role. D.It will be widely used soon.

3.What does the underlined phrase “prior to" in paragraph 4 mean?

A.Before. B.After.

C.In front of. D.Due to.

4.From which is the text probably taken?

A.A biology textbook. B.A health magazine.

C.A newspaper. D.A travel brochure.

From talking robots to driverless vehicles, technology has become so advanced that the previously impossible seems to occur on a daily basis. And yet-we still have no cure for the common cold.

Why can't we stop the common cold? According to Peter Barlow, a scientist at Edinburgh Napier University, the main challenge lies in the many different types of cold viruses that belong to the rhinoviruses(鼻病毒). There are at least 160 types.They mutate(突变) so easily that they quickly become resistant to drugs, or learn to hide from our immune systems. In other words, a single cure isn't likely to work on every type of cold.

However, researchers from Stanford University and the University of California, San Francisco, have found a possible answer. They discovered a protein(蛋白质) that the viruses need. All the viruses were unable to replicate(复制) inside cells without a gene that produces a specific protein called SETD3.

To identify the gene which produces the specific protein, researchers used a gene-editing technique to test all genes in the human genome (基因组). Namely, they randomly disabled a single gene in each of the cells, so that the cells lacked one or another of every gene in our genome. These genetically modified cells were then exposed to the rhinoviruses, which cause the common cold. The team then looked at which gene was missing in cells that continued to grow. As it turned out, the one that stood out was SETD3, which makes a protein of the same name.

Carette said the plan is to find a drug which can temporarily disable the protein, instead of producing genetically modified humans. “We have identified a fantastic target that all rhinoviruses require and depend on. Take that away and the virus really has no chance,” said Carette.

1.Which does Peter Barlow think is a problem for fighting the common cold?

A.The poor immunity of patients. B.The large variety of viruses.

C.The lack of enough cures. D.The side effects of drugs.

2.What do we know about the gene-editing study in Paragraph 4?

A.All genetically modified cells survived B.Some genes in our genome were ignored

C.It located the gene responsible for SETD3 D.It exposed the harm of the rhinoviruses.

3.How should we stay away from the common cold according to Carette?

A.Apply gene-editing to human genes B.Avoid contacts with colds patients

C.Prevent cold viruses from mutating D.Develop a drug to switch off SETD3

4.Which of the following is the best title for the text?

A.Potential defense found for cold viruses B.Secrets behind the human genes

C.Real causes of the common cold D.Puzzles over rhinoviruses solved

With rapid advances in medical science, cloning is slowly but surely looking like it could be in our near future. However, is it really an option that should be considered as a way to extend human life?

Reproductive cloning may help human families gain children, but there's also a benefit for the animal world. It brings hope to people eager for children but unable to have their own or adopt. It can also bring about the recreation of species that have long since died, allowing scientists to fully study the species as a living creature instead of simply looking at images or bones.

Many believe that cloning can be used to replace failing organs. This will reduce the waiting list for organ donations and allow more people to be saved. Not only that, but because the organ is, in fact, your own organ, there would be less chance of rejection.

Cloning could prove helpful in genetic research. Using cloning technologies, genetic researchers would have a better understanding of the composition of genes and the effects of genetic constituents (成分) on human characters. There's also the possibility of changing genetic constituents in cloned humans, and cloning could help fight genetic diseases.

While the cloning of body organs can help extend human life, it could also cause a lot of malpractice (玩忽职守). Along with the ability to clone desired characters, there could be the possibility of people deliberately reproducing undesired characters. This could lead to a rise in malpractices within society.

Cloning involves a process of creating identical genes. As such, there would be a lack of diversity in humankind. Scientists believe this lack of diversity will lower the human race's ability to adapt.

Whatever your view on cloning may be, studies show that the clone would in fact not be completely identical to the original just as twins are not completely identical. Though they might look alike, twins have different personalities and enjoy different things. The same could be said of clones. Even if technology were created in which your memories and thoughts could be transmitted (传送) to the clone, your clone would still be a different person.

1.What good might reproductive cloning bring?

A. It may help improve human well-being.

B. It could contribute to the rising birthrate.

C. It could help animals survive deadly diseases.

D. It may enable scientists to better study extinct species.

2.According to the text, cloning can also be used for ________________________________________________.

A. organ transplant

B. solving the aging problem

C. infectious disease treatment

D. constructing a gene database

3.What's one problem cloning may cause?

A. Great diversity.

B. Individual security risk.

C. Increased improper conduct.

D. Serious personality disorder.

4.Why are twins mentioned in the last paragraph?

A. To stress twins' similarities.

B. To show twins are quite common.

C. To carry out deeper research on twins.

D. To better illustrate what a clone will be like.

Connecting with people has become so much easier with advancing technology. Tasks that once required a postage stamp or carrier pigeon are now as simple as tapping a name or even a face on your screen, and you’re connected. But also easier is unconsciously getting caught up in a dilemma by violating certain new rules for communicating. A big one for some: Don’t call until you’ve texted to confirm it’s OK to call. But that’s just the beginning.

“I’m usually pretty mild and not much bothers me,” said Mark Angielle, a 29-year-old office manager from White Plains, New York. But the one thing that he hates more than anything else in life is the terrible one-word message — “K.” “At the very least reply with, Got it.” he said “At least give me a few words here. You’re not that busy.”

There are hundreds, perhaps even thousands, of others who have taken Lo social media to express their distaste for people who don’t follow the unwritten rules of digital communication.

“These rules are simply a new display of a phenomenon we’ve seen in the past,” said James Ivory, professor of communication a Virginia Tech. In the same way that generations and small groups of friends have their own slang and customs, internet culture has given birth to technology-dependent beings that have their own unique set of routine.

But not everyone gets the point. Unlike language, digital communication can be filled with ambiguous clues (线索、迹象) that the person on the other end of the call, text or email may or may not easily understand.

“As soon as people aren’t talking face to face, the first thing that gets lost is some of the richness of the body language,” Ivory said, “People immediately fill that gap by using emoji (表情符号) to sum up a feeling in seconds.

“There's great potential for danger,” Ivory warned. “What's considered polite in one form might be inappropriate or rude in another occasion.”

1.What can you infer about Mark from Paragraph 2?

A. He is a businessman with a bad temper.

B. He complains about social manners.

C. He can’t bear one- word messages.

D. He dislike a busy business life.

2.According to the text, which of the following breaks the rules for communicating?

A. John says “I got it.” to his boss face to face.

B. Jim calls Bill without confirming in advance.

C. Mary texts Lily to make sure if she can call her.

D. Jack sends “Thanks a lot” to his business friends.

3.Why may people misunderstand each other during digital communication?

A. Emoji cannot sum up feelings.

B. People use their own slang and customs.

C. There are large quantities of written rules.

D. People gets wrong messages without clear clues.

4.What are people expected to do after reading tie passage?

A. To obey their own digital communication rules.

B. To be aware of rules during digital communication.

C. To use advancing technology even with disadvantages.

D. To keep pace with digital communication development.
