2 . Robots are known as the future of technology. Robotics technology has just landed in the workplace and there is a lot of work to do. Below we'll discuss some of the best and most advanced robots ever made by humans.
Asimo
The primary focus of the robot is to help people. Asimo travels all around the world, making people aware how robots can make life easier and help humans. It can dance, run, and even kick a soccer ball. The robot can communicate with people in three different languages including Japanese, Chinese and English.
Created by: Honda (Japan)
Sophia
It is a realistic example of a perfect robot because it has about 50 different facial expressions just like humans. Sophia is primarily designed for education, research and entertainment. It travels throughout the world explaining to people the importance of robots in human life.
Created by: Hanson Robotics (Hong Kong, China)
Atlas
Its body shape is so dynamic that it can use its all body skills to move quickly and balance itself on diverse terrains (地形). The robot is capable of performing many different tasks. Its advanced AI systems make it capable of seeing barriers and negotiating through diverse terrains.
Created by: Boston Dynamics (United States)
Spot
Spot is an animal robot, or say a dog robot, because it looks very similar to a dog. Spot can search around your office, home, playground etc. as a normal dog usually does. Spot has some outstanding functions like it can map your environment, sense barriers, lift packages and more.

4 . Do you have a suit or dress in the closet that you haven’t worn for years but are reluctant to get rid of? Maybe you say, “I can’t throw that away because I paid good money for it”. If you recognize this in yourself, then you are suffering from commitment to the sunk cost fallacy (谬论). It occurs when we feel that we have invested too much to quit. This psychological trap causes us to stick with a plan even if it no longer serves us and the costs clearly outweigh the benefits.
Arkes and Blumer conducted a survey showing that people are influenced by sunk cost fallacy in their decisions. Participants imagined spending $100 on a ski trip to Michigan and $50 on Wisconsin, realizing later they were for the same weekend. They were told Wisconsin would be more enjoyable. When asked which trip to take, 54% chose Michigan despite the reasonable choice being Wisconsin, because they had made a greater initial investment.
Sunk cost fallacy takes place when we let emotions cloud our decisions. Once we’ve invested in a choice, we feel guilt or regret if we don’t follow through. We fail to realize that past costs won’t be recovered. Instead, we base decisions on past costs, ignoring present and future costs and benefits. It might be because the pain of losing outweighs the joy of winning for us. We avoid losses, making choices based on avoiding the “loss” of our past investment instead of considering the benefits gained if we don’t continue our commitment.
No one can deny the fact that we benefit a lot from perseverance. So our society loves to emphasize perseverance. Never give up! Don’t waste. But only you know the right path for you. Sometimes walking away is the hardest choice of all. You might realize a path you’re on is no longer the right one or never was. That’s a painful realization.
1. What phenomenon does the author describe in the first paragraph?| A．People benefit from sticking with a plan. |
| B．People’s consumption view has changed. |
| C．People refuse to give up the past commitment. |
| D．People’s clothes are becoming more expensive. |
| A．To save more of the loss. | B．To appear more reasonable. |
| C．To make a greater investment. | D．To enjoy more of themselves. |
| A．When we don’t continue our commitment. |
| B．When we stop feeling guilty and regretful. |
| C．When we don’t follow through our choices. |
| D．When we make decisions based on past costs. |
| A．Favorable. | B．Rational. | C．Dismissive. | D．Unclear. |

Humans work hard to avoid viruses. Sick people are isolated, diseased animals are killed and fields of infected crops are fired up. Reviving (复活) an ancient virus would surely be a disaster.
But a new study led by Fiddamanfrom Oxford, challenges this conventional wisdom. It shows how the revival of an ancient virus can unlock the secrets of its evolution.
The virus in the study is Marek’s disease virus(MDV), killing more than 90% of chickens. Yet when it was discovered in 1907, MDV rarely caused death.
Dr Fiddaman wondered whether its new-found virulence (毒性) was a result of large structural changes. To find out, he and his colleagues got their hands on nearly 1,000 chicken bones from ancient times across Europe and Asia, some of them up to 2000 years old. Sections of DNA from these remains were mapped onto the ones of today’s virus.
As the authors pieced together the sets of genes of ancient MDV, however, they noticed that the genes were arranged identically to those in modern species. It suggests that the increased virulence resulted not from large structural changes, but from point mutations (突变). In particular, changes had occurred in the arrangement of a gene called MEQ, which has an essential role in tumour (肿瘤) formation.
This discovery suggests that the ancient MDV may not have been able to cause tumours. To test this assumption, Dr Fiddaman followed up with a daring experiment. He made the ancient form of the MEQ gene and shoot it into living chicken cells. It did not turn on any of the genes associated with tumour formation. In comparison, a modern MEQ gene quickly showed its tendency to cause tumours.
By combining ancient and modern genetic biology, the methods pioneered in the paper reveal how, and more importantly why, any virus mutates. That could help scientists tackle other viruses that pull on the purse-strings of farmers—by designing new vaccines (疫苗), for instance—or even to work out how to prevent another global pandemic.
1. What does the underlined phrase “were mapped onto” mean in paragraph 4?| A．were restricted to | B．were opposed to |
| C．were compared with | D．were filled with |
| A．Point mutations in MEQ. | B．The occurrence of a new gene. |
| C．The reproduction of the ancient MDV. | D．Large structural changes in modern species. |
| A．By investigating a typical case. | B．By conducting a field survey. |
| C．By studying the related theories . | D．By doing a comparative experiment. |
| A．Viruses weaken gradually when they mutate. |
| B．The finding throws light on handling other viruses. |
| C．A global pandemic requires a world effort to end it. |
| D．Farmers will face more complex challenges than before. |
7 . How to charge an electric vehicle (EV) is one of the biggest concerns people have when working out whether going electric is right for them.
It is true that sometimes gaining access to reliable charging can seem a bit tricky.
First, download an app with a comprehensive map of the public charging points showing their locations, how powerful they are, and whether they’re working. All this is vital information because, even if you have public charging points nearby, you will need alternatives in case they’re in use.
A growing number of property owners are renting out their charging points and drive ways to other local EV drivers when they’re not using them.
For now, if charging access remains difficult for you, it’s still possible to go electric-in part.
| A．But it may be easier than you think. |
| B．It actually worked out much cheaper. |
| C．There are also other innovative ways to get your EV going. |
| D．A plug-in EV combines a petrol engine with a smaller battery. |
| E．A “fast” charger usually takes eight hours to fully charge an EV. |
| F．So you need to get a good feel for where your nearest points are. |
| G．You can find a map of homeowners whose charging points are available. |
