1 . Have you ever wondered what wild animals do when no one is watching?
Low cost, dependable and small modern cameras offered a big help. Cameras placed in hard-to-reach places have shot everything from small desert cats to larger snow-lowing cats in the northern Rocky Mountains. Scientists have been able to document the “private” moments of wildlife with leading technology.
Grant Harris is a government biologist with the United States Fish and Wildlife Service in Albuquerque, New Mexico. In his words, “there’s no doubt that these wild cameras are important tools to learn new information on wildlife.” Harris said some images help scientists see the influences of climate (气候) change.
Researchers with the Wyoming Migration Initiative, or WMI, are among those using wild cameras along with global positioning systems, or GPS. But WMI director Matthew Kauffman says as those devices (设备) are limited (有限的), so is the amount of information they can gather. However, cameras can be left in very wild areas for days, weeks or even months. They can provide information on how many animals are moving over a given period of time.
Putting those cameras in place requires careful planning. Wild video can show details about animal behavior. However, wild cameras have their problems too. Animals such as wolverines and bears sometimes attack (袭击) them. Scientists do not know if the attacks are the result of anger or interest. Also, the devices have become popular tools to help hunters look for animals. Some people argue that it is unfair to use the cameras that way.
Even with such problems, wild cameras are clearly an important scientific tool in researching wild animals.

2 . The nine woman of Bella Mondo win over yet another audience. The group is one of just a handful of all-women ensembles (乐队) in Ivory Coast.
It all started in 2007. Prisca Allou was a music student. A music producer came to see her. He said he wanted to make an all-female ensemble to keep a promise to his late mother.
Allou got on board and was charged with recruiting (招募) other members. “It wasn’t easy at first. Some parents were against it. You know, in Africa, the place of women is often seen as being either in an office or at home. That was the fixed image.” Allou spread the word and took out ads in local papers. Most of the girls she found were not professional players. “I just played some tamtam. I learned to play drums when I joined Bella Mondo.” The girls spent the next four years learning to play their instruments. Many gave up along the way, but eight of them soldiered on with Allou, and Bella Mondo was founded.
The band plays original songs and covers. Their music spans a wide range of styles: funk, reggae, pop music. They released their first album in 2013... and have performed in Paris, Dakar, Cotonou and, of course, here at home in Abidjan.
You can see them nearly every Thursday at this bar, the same place that gave the band its start years ago. “Oh yes, I was surprised at first. A woman singing, you see that every day, but an entire band, playing all the instruments and everything? It was extraordinary. I was dumbstruck. Bella Mondo is a great band.”
The women are now working on their second album.

3 . The end of the school year was in sight and spirits were high. I was back teaching after an absence of 15 years, dealing with the various kinds of "forbidden fruit" that come out of book bags. Now was the spring of the water pistol.
I decided to think up a method of dealing with forbidden fruit.
"Please bring that pistol to me," I said. "I'm going to put it in my Grandma's Box."
"What's that?" they asked.
"It's a large wooden chest full of toys for my grandchildren," I replied,
"You don't have grandchildren," someone said.
"I don't now." I replied. "But someday I will. When I do, my box will be full of wonderful things for them."
My imaginary Grandma's Box worked like magic that spring, and later. Sometimes. students would ask me to describe all the things I had in it. Then I would try to remember the different possessions I supposedly had taken away—since I seldom actually kept them. Usually the offender would appear at the end of the day, and I would return the belonging.
The-years went by, and my first grandchild Gordon was born. I shared my joy with that year's class. Then someone said, "Now you can use your Grandma's Box." From then on instead of coming to ask their possessions back, the students would say, "That's okay. Put it in your Grandma's Box for Gordon."
I loved talking about the imaginary box, not only with my students but also with my own children. They enjoyed hearing about all the forbidden fruit I had collected. Then one Christmas I received a surprise gift—a large, beautifully made wooden chest. My son Bruce had made my Grandma's Box a reality.

They told the policeman their story. The policeman asked them to bring the girl to his office. However, when the policeman saw her, he became taken with
The king asked them to bring him the girl. When the king saw the girl, he said, “Oh, the girl should marry a king like me.” They all argued with each other.
Then the girl said, “I have a solution. I’m going to run and you’ll run after me. I’ll be the wife to the one who catches me first.” The four men all agreed and ran after her. While running after her, they suddenly fell into a deep hole. From the top, the girl looked at them and said, “Now, let me tell you who I am.”

5 . The first “mobile phone sidewalk in China” has appeared at a scenic spot in Chongqing. The sidewalk—3 meters wide and 50 meters long—was built in the Yangrenjie Scenic Spot. It separates pedestrians along two pathways. One is for cell phone users to walk on; the other is for those without cell phones.
A warning sign shows: Cell phones walk in this lane at your own risk. “In my mind, these sidewalks help a lot in minimizing security risks for mobile phone addicts,” said Wang Li, a local resident who doesn’t use a mobile phone often. Cases of mobile phone users being injured while using their phones and ignoring their surroundings have been reported by the media. Tourists who were attracted to the sidewalk took photos of it. But many did not comply-with the regulation, and someone even parked a car on the sidewalk.
Li Zhijiang, a 20-year-old college student from Guizhou, regarded the sidewalk as great progress. “I knew there were such sidewalks in Washington’s central business district, which are very necessary for the addicts, especially in the busy streets,” Li said. Anthony Edwards, a 28-year-old actor from England, was enthusiastic, saying it was an improvement over his home country. However, his Chinese colleague, Xing Xing, thought the sidewalk was “pointless”, but added a grudging (勉强的) acknowledgement: “Setting up special sidewalks could be a solution to reducing security problems in particular situations. But this kind of sidewalk is not a fundamental solution and could be an indulgence (嗜好) for mobile phone addicts in the long run in my mind and this could even lead to more problems in the future.”
With the increasing popularity of smartphones, more young people in China are glued to them, a phenomenon that worries many experts. It is estimated that the number of smartphone users in China will be more than 500 million this year.

6 . Time and how we experience it have always puzzled us. Physicists have created fascinating theories, but their time is measured by a pendulum (钟摆) and is not psychological time, which leaps with little regard to the clock or calendar. As someone who understood the distinction observed, ''When you sit with a nice girl for two hours it seems like a minute, but when you sit on a hot stove, a minute seems like two hours. ''
Psychologists have long noticed that larger units of time, such as months and years, fly on swifter wings as we age. They also note that the more time is structured with schedules and appointments, the more rapidly it seems to pass. For example, a day at the office flies compared with a day at the beach.
Expectation and familiarity also make time seem to flow more rapidly. Almost all of us have had the experience of driving somewhere we've never been before. Surrounded by unfamiliar scenery, with no real idea of when we’ll arrive, we experience the trip as lasing a long time. But the return trip, although exactly as long, seems to take far less time. The novelty of the outward journey has become routine.
When days become as identical as beads (小珠子)on a string, they mix together, and even months become a single day. To counter this, try to find ways to interrupt the structure of your day-- to stop time, so to speak.
Learning something new is one of the ways to slow the passage of time. One of the reasons the days of our youth seems to be full and long is that these are the days of learning and discovery. For many of us, learning ends when we leave school, but this doesn't have to be.

7 . 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.
1. Which of the following will Dr Dimitrios agree?| A．Cars can talk with drivers using 5G. |
| B．5G will improve the safety of car driving. |
| C．Massages sent by 5G will never be delayed. |
| D．Over 1.3 million deaths are caused by driverless cars. |
| A．changing their speed | B．turning to another route |
| C．getting closer to the danger area | D．sending warnings to nearby cars |
| A．Recovery. | B．Push. | C．Danger. | D．Fame. |

8 . Plenty of science fiction (sci-f) movies over the decades have shown us different versions of Mars. The truth about the Martian surface might be exciting because it's real. And with NASA' s Mars 2020 mission set to launch this summer, we're facing more discovery.
So far, thanks to a decade of research enabled by NASA's Curiosity rover, we've learned that lakes, rivers streams and likely oceans used to appear on Mars. While its water disappeared over three billion years ago, it tells us that Mars used to be habitable. This knowledge confuses us because so far, we've seen no clear evidence of life there, not even a virus. But if Mars was once habitable, wouldn't it have life?
NASA is now prepared to take the next step to answer this question with the launch of another rover, Perseverance. Every time a rover goes to Mars, it just stays there, with no way to fly back home. So we have never brought rock or soil samples back from Mars.
Perseverance rover will change this. Its primary and unique purpose is to collect samples that a future spacecraft can return to Earth. These samples will tell us more about the geologic history of Mars than anything we've learned, which is already a lot. Since 2012. the Curiosity rover has traveled more than a dozen miles, making observations along the way with its 10 instruments.
Thanks to data from the Curiosity rovers Sample Analysis at Mars instrument, we know that Mars does indeed have organic materials. That’s more complex than we expected to find on the surface of Mars. And that's exactly why we want to gather the most interesting samples and bring them back to Earth. We expect to find out much more about Mars once we get samples back from the Mars 2020 mission.

9 . From linguists’ point of view, grammar is a set of patterns for how words are put together to form phrases or clauses, whether in spoken or written. Different languages have different patterns. Some scholars have tried to identify patterns common to all languages. But apart from some basic features, few of these so-called linguistic universals have been found.
The study of these patterns open up “an ongoing debate” between two positions, known as prescriptivism and descriptivism. Prescriptivism thinks a given language should follow consistent rules, while descriptivism sees variation and adaptation as a natural and necessary part of language.
Language purists(纯化论者) worked to establish and promote this standard by detailing a set of rules that reflected the established grammar of their times. And rules for written grammar were applied to spoken language as well. Speech patterns that deviated from the written rules were considered signs of low social status. And many people who are grown-ups speaking in these ways were forced to adopt the standardized form.
More recently, however, linguists have understood that speech is a separate phenomenon from writing with its own regularities and patterns.We form our spoken skills through unconscious habits, not memorized rules. And because speech also uses mood and intonation for meaning, its structure is often more flexible, adapting to the needs of speakers and listeners. This could mean avoiding complex clauses that are hard to understand in real time, making changes to avoid awkward pronunciation or removing sounds to make speech faster.
But while the debate between prescriptivism and descriptivism continues, the two are not mutually exclusive. Like language itself, it’s a wonderful and complex fabric woven through the contributions of speakers and listeners, writers and readers, prescriptivists and descriptivists from both near and far.

10 . “What's your ‘Thing of the Day’？”I asked my fourteen-year-old son as he got a piece of potato onto his plate. This is a question our four kids and whichever friends are staying for supper expect to be asked each evening at suppertime. Usually, it's followed with, “Uhh……Umm…We had pizza for lunch. ”And then I have to refuse the response and ask for something meaningful-either something he learned or something that happened with his friends.
But, this day, my son surprised me as he went into great detail about how he had been honestly wronged by a couple of classmates and laughed at in front of the class. I asked more questions and learned that the teachers were aware of the situation. The issue had been dealt with as much as the teachers and staff were able to. It was really just a matter of kids being mean and deciding to play a trick on someone.
I thought about the situation all night. I vacillated between meeting the teachers, meeting the parents of the classmates, and not doing anything since the story had been told to me in a matter-of-fact way-not overly excitedly.
I waited until the next day after school. On the car ride home, I questioned my son what about today after yesterday's situation. My son was surprised that I brought it up again. “What？No, it's over, Mom. They're my friends. They were just being stupid. They apologized. Forgive and forget, you know？We're all good. ”
I was worried that perhaps he was trying to hide his concern or sadness about the thing. But as I watched him over the next days and weeks, everything seemed “normal”. Wouldn't it be great if everyone could live the “forgive and forget” way of life？
