1 . Cars could be able to "talk" to each other to warn about dangers on the roads using 5G technology in future, according to researchers.
Researchers at Glasgow Caledonian University (GCU) believe 5G may enable driverless cars to send each other messages about dangers such as ice or deep holes.
And they believe the high-speed, low -delay (低延迟的) nature of 5G will improve driverless cars to the point where they will be safer than the cars being driven today. They predict the number of road traffic accidents which cause more than 1. 3 million deaths and up to 50 million people injured worldwide every year will drop greatly as a result.
Dr Dimitrios, a member of the research group, said, “To have a better idea of what the future will look like, think of having cars that not only use sensors (感应器) to find what's around them, but also can talk to each other about safety information nearby.”
“I'm sure anyone who has had a bad experience on frozen roads would have benefited from knowing about the dangerous conditions ahead of time so they could have changed their speed or, if possible, even avoided that route (路线) altogether.”
With the help of 5G, an early warning system in vehicles will come into use within the next few years. Cars that are close enough to the danger area will pass warning messages to other cars around them using communication technologies, but also to cars further away using 5G, fast and reliably. Then those cars will send the same information to cars near them and 80 on, forming a joined-up.
5G is an exciting mobile technology, which will give a great boost to smart cities and autonomous (全自动的) vehicles among many other things.

2 . Stephen Hawking was regarded as one of the most brilliant physicists in history. His work on the origins and structure of the universe, from the Big Bang to black holes, changed the field greatly. His best-selling books also appealed to a number of readers.
Stephen Hawking had a challenging life. He was born in England on Jan.8, 1942-300years to the day after the death of the astronomer Galileo Galilei. He attended University College, Oxford, where he studied physics, despite his father’s urging to focus on medicine. Hawking went on to Cambridge to research cosmology.
In early 1963, just before his 21st birthday, Hawking suffered from a serious disease more commonly known as Lou Gehrig’s disease. He was not expected to live more than two years. Completing his doctor’s degree did not appear likely. Yet, Hawking had overcome the great difficulties, not only attaining his Ph. D. but also building new roads into the understanding of the universe in the decades since.
Hawking continued at Cambridge after his graduation, serving as a research fellow and later as a professional fellow. In 1974, he was inducted（正式就职）into the Royal Society, a worldwide fellowship of scientists. In 1979, he was appointed Lucasian Professor of Mathematics at Cambridge, the most famous academic chair in the world.
As the disease spread，Hawking became less mobile and began using a wheelchair. Talking grew more challenging and, in 1985, an emergency tracheotomy（气管切开术）caused his total loss of speech. A speech-generating device was constructed at Cambridge, combined with a software program, serving as his electronic voice and allowing Hawking to select his words by moving the muscles in his cheek. Hawking died on March 14, 2018.

3 . Researchers at Cornell University are one step closer to building robots that are more like humans. This new method is one you might not expect. However, a soft robot muscle that "sweats" to regulate its temperature. "Sweating takes advantage of evaporated (蒸发)water loss to rapidly dissipate heat and can cool below the environmental temperature. So as is often the case, biology provided an excellent guide for us as engineers."
The fingerlike devices are 3D printed, water powered, and can be used to grab things. They are made of two soft chemical materials: a base layer of (CH3) 2 CH-C3H5 NO covered in a multihole layer of (C3H5 NO)n. When the fingers reach a temperature of 30°C (86°F), the base layer reacts by shrinking, squeezing the water through the top pores (毛孔)in the top layer. The drying up is so efficient that the surface temperature of the actuator can drop by 21°C in just 30 seconds. That's three times more efficient than in humans. When wind from a fan is thrown into the mix, they cool down around six times as fast. The evaporation also cooled the object held by the actuator hand.
"The best part of this artificial strategy is that the heat regulation is based on the material itself," said T. J. Wallin, co-lead author, a research scientist at Facebook Reality Labs. "We did not need to have sensors or other components to control the sweating rate. When the local temperature rose above the set point, the pores would simply open and close on their own. "
While the result is exciting, it is only a first step. The robot has its weaknesses. The sweat can make the robot hand slippery, so the team is examining textures to improve its grasp. When the sweating takes place, the robot's mobility is also blocked and needs to refill its water supply.
"I think that the future of making these more biologically similar materials and robots is going to rely on the material composition," said co-lead author Rob Shepherd, an associate professor of mechanical and engineering. "This brings up a point about the importance of research involving several different academic subjects or areas, where really no one group has all the answers. "

4 . A solar-powered car that can be charged as it runs is being tested in Germany.
Munich-based manufacturer(制造商)Sono Motors has built the new type, named Sion, and will likely help the European powerhouse hit its national target of 1 million electric cars on the road by 2020.
Sono Motors has solar cells fixed into Sion’s bodywork, with a total of 330 solar cells built into the roof, bonnet and sides of the vehicle. These enable the vehicle’s battery to be charged when sunlight is hitting the solar cells, whether it is on the road, or parked in the sunny spot in a car park.
The solar-powered vehicle is set to be launched in Germany in 2019.
Sono Motors wants Sion to be universal and allows the car to be charged using solar energy as well as conventional outlets(电源插座), so car owners aren’t left on cloudy days.
The firm has made a 2019 date for mass production, which will be undertaken(承担) by a European manufacturer. Some 6,500 people have already placed orders for the electric vehicle. Prices for Sion tend to start from € 16,000 next year. The all-electric vehicle will offer a range of around 250 km before the battery runs out completely and it needs recharging either by solar power or using a wall plug, the company said.
Sion was designed originally as an environmentally conscious car, but will also include a number of features designed around comfort to help it compete with other modern vehicles.
“We have a seat heater, air conditioning, and a large entertainment system where I can also connect my phone, which means I really have a full vehicle,” Laurin Hahn, co-founder of the company told Reuters.
1. From the third paragraph we can know that .| A．the car is popular on the road | B．the car has a very large battery |
| C．there are 330 solar cells on the car | D．where there is sunlight, Sion can be charged |
| A．design | B．release | C．improve | D．recall |
| A．Because it is made from the rainproof material. |
| B．Because it can be charged by clouds on cloudy days. |
| C．Because it can store a great deal of energy. |
| D．Because it can be charged by conventional power outlets. |
| A．Modern, powerful and popular. | B．Environmental, comfortable and competitive. |
| C．Environmental, cheap and simple. | D．Expensive, fashionable and energy-saving. |
5 . It happens from time to time that after a whole morning of studying, you are tired in the afternoon. It’s then that you might want to eat something sweet, perhaps a Coke or a chocolate bar, to lift your mood. After all it’s popularly believed that a “sugar rush” gives us energy.
But a study published in Neuroscience and Biobehavioral Reviews in April suggests that sugar can make us feel worse rather than boost our moods.
The German and UK researchers collected data from 31 studies involving nearly 1,300 adults. They studied the effect of sugar on various aspects of mood, including anger, alertness, depression and tiredness.
They found that people who have too much sugar become more tired and less alert within an hour and that these feelings become more intense over time.
According to the researchers, when people take in sugar their blood sugar levels rise rapidly, leading to a burst of energy and a short “feel good” period. However, as they begin to digest the sugar, their blood sugar levels decrease quickly leading to a bad feeling.
To remain on a “high” people are likely to eat more and more sugar until they become addicted to it. As with caffeine, this prevents the body from relaxing, leaving people feeling tired and less alert.
But the study findings needn’t make us think we must give up sweet food altogether. According to the World Health Organization, it is healthy to have the sugars found naturally in fruit, vegetables and milk so long as these make up less than 5 percent of daily total energy intake.
So the next time you feel tired and can’t concentrate, perhaps you should think twice before you bite into a chocolate bar. Maybe a spot of exercise at midday would be a better idea!
Tips for beating afternoon fatigue.
* Head outside and sit in the daylight for 10 minutes.
* Get into the routine of a mid-afternoon cup of tea.
* Plan group activities for midday.
* Add variety to your routine.
1. What does the underlined word “boost” in Paragraph 2 probably mean?| A．harm | B．improve | C．control | D．change |
| A．They felt more tired. | B．They felt relaxed. |
| C．They were more alert. | D．They felt energetic. |
| A．Our mood is connected to our blood sugar levels. |
| B．Taking in more sugar benefits mental health. |
| C．Getting caffeine is another way to relax. |
| D．Sugar and caffeine are all the same. |
| A．Give up sweet food. | B．Have a bar of chocolate. |
| C．Do an hour of exercise. | D．Eat foods with natural sugars. |
6 . Reading instruction in the classroom is a key concern for all teachers and there are many ways to go about it. However, is our determination to achieve excellence in reading skills in our children killing their love and enjoyment of a good book?
In my work with parents, I am frequently asked the best ways to encourage reluctant readers to be engaged with books. Parents report that their children return home from school with no inclination to pick up a book and read.
Any eager reader will gladly talk about the joy with a good book to read away the hours on a cold, rainy afternoon. Reading a good book is one of life’s greatest pleasures. We need to share these experiences with our children in order to assist them in developing into strong readers. But the use of boring, mass-produced home reading texts in children’s early years at school can be seen as the beginning of this negative cycle.
As children progress through their schooling life, there are many other instances of learning reading skills that don’t help reading development. Frequently, teachers feel the pressure to give their students “just enough” in terms of reading strategies to be able to achieve the test, which leaves little time to focus on reading for pleasure.
Kelly Gallagher, a high school teacher, outlines the term “Readicide” in his book. He says it’s: the systematic killing of the love of reading, often worsened by foolish, boring practices found in schools.
Recent research shows that many teachers tend to follow the traditional literacy practices that they have experienced in their own education, which can often have negative intentions for their students.
While teaching children key concepts for analyzing and evaluating texts is important, the manner in which it is done and time that is spent on this can lead to unexpected results. Schools aren’t to blame when it comes to not arresting students’ lack of interest in reading, but they have an important role to play in fostering reading enjoyment.
1. What does the underlined word “inclination” mean?| A．Energy | B．Task |
| C．Intention | D．Requirement |
| A．To develop reading habits | B．To read for pleasure |
| C．To learn reading skills | D．To kill a love for books |
| A．focus on teaching reading strategies |
| B．ignore key concepts for analyzing texts |
| C．are to blame for students’ poor reading |
| D．fail to follow the traditional reading practices |
| A．Reading books is to experience pleasure |
| B．Learning to love books is even more important |
| C．Teaching reading helps reluctant readers |
| D．Getting pleasure from books makes capable readers |
7 . Have you ever thought that music can have an effect on animals? Dr. Fisher has put music in over 1,100 animal shelters, saying that it makes dogs and cats quiet and even cuts down on barking. Fisher asked artists around the world to share dog-and-cat friendly music. She gives it free to animal shelters.
One fan was Tina. Winter temperatures at the rural shelter for six dogs and six cats usually ran below zero and the wind blew nearly every day. To calm the animals, Tina tried the radio. Besides poor reception, the news and sports had people shouting and crying loudly. “The difference is great. ” she said. So she and her husband had to buy a second player for the cats. “When we play songs they like, they go and sit by the speakers. ” Tina said.
No one has studied the impact of Fisher’s music idea. But others have looked at how music and noise in general affected animals. A study found that animals were more likely to sleep and less likely to bark when Mozart, Beethoven and other similar music were playing, but not when heavy metal and other sounds were.
A survey of more than 500 shelters guided by Fisher validated her idea, finding barking reduced by half and animals more relaxed. It just destresses them.
Beyond the music, the shelter staff do what they can to reduce stress for the dogs, including toys, food and spending time with them. “Reducing their stress helps them show off their personalities and they can get adapted more quickly,” said Fisher. “The music also helps relax staff members and that benefits the animals too.”
1. When dogs listen to dog friendly music. They will _______.| A．calm down | B．get excited |
| C．become clever | D．never bark |
| A．doubted | B．refused. |
| C．proved | D．changed |
| A．Reducing stress is of great benefit to the dog. |
| B．The dogs in the shelter are fond of toys. |
| C．It is hard for the dogs to be adapted. |
| D．The staff members also like classical music. |
8 . History tells us that footwear was one of the first things ancient people learned to make. Footwear helped them across rocky paths or hot sands without injuring themselves. The earliest footwear we know of was simply a piece of plaited (编织的) grass or leather tied to the feet.
The ancient Egyptians seem to have invented the first footwear with a firm sole (鞋底) — sandals. Egyptian royalty usually wore sandals that had a different style from those with lower status (身份), while slaves were not allowed to wear anything on their feet. The sandal is still the basic form of footwear in many countries, particularly those with a hot climate, whereas in cold climates, an entirely different type of shoe appeared — the moccasin — a slipper-shaped shoe made of soft but strong leather.
The Greeks were the first to develop shoes with heels (鞋跟). Then, in the Middle Ages, shoes with long points at the toe became very chic for the nobility. These shoes were often very difficult to wear. Other trends followed, with square-toed shoes, wide shoes, and even shoes that could make a woman stand two feet taller. Not surprisingly, these sometimes led to accidents. Even today, fashion rather than comfort often leads to the kind of shoes women wear.
Mechanical shoemaking appeared in the 1800s in North America. Until then, shoes had been made with the same kinds of hand tools used by the ancient Egyptians. And in 1858, a machine was invented that could stitch (缝合) the sole of a shoe to the upper part. Now it was possible to make shoes that were shaped to fit either the left or right foot. Toward the end of the 1800s came a new type of shoe that was specifically designed for sports — the sneaker — and it soon become an all-time favorite.

9 . Do you live in a city? You’ve probably noticed how noisy and crowded life in a city can be. What if you could live next to a calm lake instead?
As it turns out, living near bodies of water – lakes, rivers, ponds, even oceans – can help us feel both happier and healthier. Those who live less than a kilometer from the coast are around 22 percent less likely to have mental health problems than those who live 50 kilometers or more away, according to a study by researchers from the University of Exeter, UK. People who visit the coast at least twice a week tend to experience better general and mental health as well.
So how does “blue space” make us feel better? For one thing, aquatic environments tend to have less pollution and more sunlight, both of which are linked to better mental and physical health. People who get more sun tend to be happier than those who do not.
There’s also the air above the sea. After spending time near the ocean, you might find that you feel more relaxed than usual. This is because sea air is filled with negative ions（负离子）. These ions balance our levels of serotonin（血清素）, a chemical that affects our moods. With balanced serotonin levels, we feel more calm and relaxed, according to Daily Mail.
Finally, people who live near water tend to be more physically active, according to the Guardian. Water sports like swimming and rowing can help us stay in shape, which in turn keeps us healthy.
1. What did the researchers from the University of Exeter find?| A．Living near water can improve our mental health. |
| B．An increasing number of people don’t like living in cities. |
| C．Living near water has more advantages than living in cities. |

10 . Nottingham Goose (鹅) Fair started on the first Thursday in October and lasted 3 days. However, nowadays you won’t find any geese there.
The fair opened at 12:00 on the Thursday by the Lord Mayor of Nottingham, but it has an interesting and shocking history.
For starters, it wasn’t always the largest fair in the area. And the main fair for the people of Nottingham in terms of trade and economy was the Lenton Fair held at Lenton Priory.
In the Middle Ages the Lenton Fair overshadowed (使显得逊色) the Goose Fair in size and importance. Harrisons Calendar of Fairs for 1587 mentions the Lenton Fair but not the Goose Fair. However, the Goose Fair competed with its local competitors and every year over 20,000 geese from the Fens in Lincolnshire arrived to be sold to provide the traditional Michaelmas dish.
It wasn’t just for geese either. All kinds of things were sold at the Goose Fair: sheep, horses and cattle were also sold.
The fair has been under threat of closure many times over the years. In 1764 they actually had cheese riots (暴乱) due to an increase of a third on the price of cheese compared with the previous year, which resulted in an attack on the stallholders (摊主) at the fair.
By 1880 the fair was reduced to a three-day event, which started on the first Thursday of October. In 1928 the fair was moved from the market square to its present site in the forest which is far away from the city centre. Despite attempts throughout its history to prevent the fair, the income from rents paid by the stallholders is financially beneficial to the local government. So regardless of the cheese riots and the various attempts to prohibit it, Nottingham Goose Fair has survived to celebrate over eight centuries of fun.
