7 . In the 1997 movie Contact, a scientist, played by actress Jodie Foster, detects a radio signal — the first communication from an extraterrestrial (外星的) civilization. That story, composed by Carl Sagan, is a fiction. But the search for such a signal is not a crazy story. Real scientists look to the sky, using powerful radio telescopes, hoping to hear even a whisper of a radio signal from one of our neighbor planets.
Indeed, a recent report of a transmission originating from Proxima Centauri, the closest star to our own, was reported by the British newspaper The Guardian in December. The source of the story is not a scientific paper, but instead it seems to have been leaked by an unknown source. The claim of a signal, if it turns out to be truly a sign of extraterrestrial intelligence, would be one of the most important discoveries of all times.
In April and May of 2019, the 64-meter-wide Parkes radio telescope, located in Australia, was recording radio transmissions from the direction of nearby star Proxima Centauri. Over the course of hours, the telescope documented data from the star every half an hour, before staying away to look at a different direction. This procedure, called “nodding” was used to make sure that any observed signal is coming from a particular direction, rather than just random radio noise.
This signal was not immediately noticed; it was over a year after the data was recorded that Shane Smith, an assistant with Breakthrough Listen, found it buried in the telescope’s recordings. This was in late October 2020. So, what exactly was seen? It was a radio signal at a single frequency, specifically 980.002 MHz. It was observed to have originated in a small patch of the sky, about half the diameter (直径) of the full moon, centred on Proxima Centauri.
First and foremost, it is important to note that astronomers think it is highly unlikely that the signal is caused by space aliens trying to communicate with us. However, astronomers mentioning the significance of the signal cannot be ignored.

8 . Do you feel bitter about others’ personal integrity around?
They Touch or Cover Their Mouth
If the person you’re talking to put their hand over their mouth, it’s a good signal indicating (表明) they are unwilling to answer a direct question or reveal something true.
They Repeat Words or Phrases
When a person is telling the truth, they can recall everything without thinking about it. On the other hand, when someone is telling a half-truth or a total lie, they often repeat themselves over and over to convince you of their words.
They Use Inconsistent Gestures
Inconsistent gestures bring a visual element to the concept you’re trying to convey, like shaking your head when you say no, or nodding to indicate yes. Inconsistent gestures, therefore, are those that don’t go with this concept.
Keep in mind that there is no fixed proof that someone is lying.
A.They tend to avoid direct questions by looking around. |
B.It is common for liars to use rude gestures like pointing. |
C.Big liars may expose the truth through their body language. |
D.Surely you do since they are dishonest with you involuntarily. |
E.They’re unconsciously putting a barrier between themselves and you. |
F.It’s also a strategy to help the liar buy time to compose the next part of their story. |
G.Nevertheless, it is a good place to start if you want to learn to recognize small clues. |
9 . A wise driver keeps an eye on the fuel indicator (指示器), to make timely stops at filling stations. For drivers of electric cars, though, those stations are scarce. The facility needed for refilling batteries has yet to be developed, and the technology that facility will use is still not available at the moment. Most electric cars are equipped with plugs. But plugs and their connected cables and charging points bring problems. The cables are easy to trip passers-by. The charging points lead to more street jams. And the copper wire involved attracts thieves easily. Many engineers would, therefore, like to develop a second way of charging electric cars—one that is wireless and can thus be buried underground.
Electromagnetic induction (电磁感应), the fundamental principle behind wireless charging, was discovered by Michael Faraday in 1831, and is widely used in things such as electric motors and generators. Faraday observed that moving a conductor through a magnetic field generated a current in that conductor. Further investigations showed that this also works if the conductor is fixed and the magnetic field is moving. Since electric currents generate magnetic fields, and if the current changes so does the field, a changing current creates a field that is constantly moving. This means that running such a current through a conductor will generate a similar current in another, nearby, conductor. That generated current can then be used for whatever purpose an engineer chooses.
In the case of electric car charging, the first conductor is a length of copper wire. This is rolled up around a piece of ferrite (铁氧体) that strengthens the magnetic field generated. The whole device is packed in a flat case that can be easily buried underground. When a car equipped with a suitable “pickup” stops or parks above this device, and changing current is fed into it, a similar current is generated in the pickup. This is then turned into direct current, and is used to charge the car’s battery. The principle is thus pretty simple. But only in recent years has it become practical to use in electric cars.

10 . The summer holidays have just begun, but it is a busy morning at Cadoxton Primary School, in Barry, an industrial town in Wales. It runs a summer programme for hard-up (拮据的) children, providing meals and activities over the holidays with the aim of helping kids to spend the time more meaningfully. As young people run laughing and screaming into the school cafeteria for breakfast, their parents hung out, some visibly relieved. Just three days into the six-week school holidays one mother says her nine-year-old daughter has already asked five times to go bowling. “Without the school’s help,” she says, “it would be a long and expensive six weeks.”
In the popular imagination, school summer holidays conjure up (使……呈现于脑际) a picture of carefree youthful exploration. But many parents rely on the term-time services that schools give their kids, such as tutors and meals. If the holidays approach, they can suddenly find their schedules and budgets stretched. Researchers also say that the long break often sets back children’s learning, and that children from poorer backgrounds are desperately affected due to their shortage of money.
Many poor children fall behind their wealthier peers over the holidays. “Summer is the most unequal time of the year,” says Matthew Boulay of the National Summer Learning Association. “Well-off parents can fill the gap left by school and consolidate (使巩固) their children’s unfamiliar knowledge well, keeping their children stimulated with summer camps, trips abroad or private tutors. Poorer families, apparently, find this harder, since their income is relatively low and demand for sponsored activities offered by governments,” he adds.
Holidays can be a financial stress, which is absolutely true. In countries where some children receive free school meals, summer means bigger grocery bills for hard-up families. Households where both parents work have to pay for extra childcare, too. The Family and Childcare Trust, a charity, says that in Britain, where childcare costs are the highest in the OECD, a club of mostly rich countries. Parents will spend an average of 33 per child per week on childcare this summer, mainly because of the sharp shortage of governmental funding sponsor.
