21、The moon may shine white above us most nights of the year, but how much do we know about Earth’s neighbor and what lies beneath its surface? Scientists are aiming to find out.
On Jan 3, 2019, China’s Change 4 spacecraft landed on the far side of the moon a first for humanity. It released a small probe（探测器）,Yutu 2, or Jade Rabbit 2, which began to search beneath the moon’s surface using Lunar Penetrating Radar（探测雷达）. These radio signals can reach 40 meters underground, three times the depth of the Chang’e 3 lunar probe launched in 2013 for the near side of the moon, China Daily reported.
In a study published in the journal Science Advances, researchers found that the lunar soil’s top layer on the far side of the moon was much thicker than expected ﹣ about 40 meters. Other scientists only expected about 6 millimeters of soil based on NASA observations during the Apollo moon landings, according to The New York Times.
“It’s a fine, dusty, sandy environment, said one of the authors of the study, Elena Pettinelli, a physics and mathematics professor at Rome Tre University, Rome.
Yutu 2 is specifically exploring the Von Karman crater（大坑）,a large hole that’s 180kilometers wide and also the landing site of Chang’e 4. It’s part of an even larger, older crater spanning more than 1,770 kilometers.
“The subsurface at the Chang’e 4 landing site is very complex,” said Li Chunlai, a research professor and deputy director﹣general of National Astronomical Observatories of the Chinese Academy of Sciences. Observations suggest that the subsurface material is totally different than the previous landing site of Chang’e 3, she said.
Radar waves revealed various layers beneath the moon’s surface: grainy（ 颗粒状的）material, boulders（岩石）,and further layers of fine and coarse（粗糙的）particles. This information is helping scientists to gain new understanding of the moon’s history and formation, as well as volcanic activity and lunar impacts.
Yutu 2 is the longest﹣working rover（巡视器）on the moon, but it won’t last forever. China plans to launch the Chang’e 5 probe later this year, Xinhua News Agency reported. The spacecraft is expected to bring pieces of the moon back to Earth for closer study.

22、 Scientists say they've developed a system using machine learning to predict when and where lighting will strike. The research was led by engineers from the Swiss Federal Institute of Technology in Lausanne, Switzerland.
European researchers have estimated that between 6,000 and 24,000 people are killed by lightning worldwide each year. The strikes can also cause power outages, destroy property, damage electrical equipment and start forest fires. For these reasons, climate scientists have long sought to develop methods to predict and control lightning. In the United States and other places, ground-based sensing devices are used to identify strikes as they happen. But, no system has been created to effectively predict lightning.
The system tested in the experiments used a combination of data from weather stations and machine learning methods. The researchers developed a prediction model that was trained to recognize weather conditions that were likely to cause lightning.
The model was created with data collected over a 12-year period from 12 Swiss weather stations in cities and mountain areas. The data related to four main surface conditions: air pressure, air temperature, relative humidity and wind speed.
The atmospheric data was placed into a machine learning algorithm（算法）, which compared it to records of lightning strikes. Researchers say the algorithm was then able to learn the conditions under which lightning happens.
Amirhossein Mostajabi is a PhD student at the institute who led the development of the method. He said, “current systems for gathering such data are slow and complex and require costly collection equipment like radar or satellites.”
“Our method uses data that can be obtained from any weather station,” Mostajabi said. “This will improve data collection in very remote areas not covered by radar and satellite or in places where communication systems have been cut,” be added.
The researchers plan to keep developing the technology in partnership with a European effort that aims to create a lightning protection system. The effort is called the European Laser Lightning Rod project.

C.the atmospheric data. D.the machine learning algorithm.
【4】What can we learn about Mostajabi from the passage?
A.He developed the method and the system himself.
B.He thinks the current systems are too slow and simple.
C.He is a professor at the Swiss Federal Institute of Technology.
D.He believes their system does much better in data collection.
23、On a cold winter day in Denver, I waited in line to see my hero, Jack Canfield, the co-author of the best-selling Chicken Soup for the Soul series and the author of The Success Principles. What Jack had become was a version of what I wanted to be.
During his talk, Jack took out his wallet, pulled out a hundred-dollar bill, and said, “Who wants this?”
Hands shot up in the audience; people leaned forward to see whom Jack would choose. But I ran up the stairs to the stage and grabbed the bill from his hand. He turned to me and said, “Yes, that’s it! Instead of waiting around for opportunities, simply take the initiative and create what we want!”
After this week, I asked for his personal e-mail address and sent him e-mail sharing my views and dreams. He kindly e-mailed back simple encouragement such as “Keep thinking and playing bigger; it’s much more fun that way. Love, Jack.” Then I got occupied with other things in life and I stopped e-mail Jack.
A year later, my dream gradually faded. I had this idea if I got back in touch with Jack. I e-mailed him again and again but got no response. As I sat down at my computer to check my e-mail for the fifth time in 15 minutes, an inspiration came like lighting: What was I doing? Was I waiting for the prize of life? I knew I needed to do something about all this waiting. I was going to write a book, which I would call “Waiting for Jack”!
It all sounded good, but then reality hit. Some nights I cried and wanted to give up. I wrote and rewrote. Even though I could feel the fear, I did it anyway. Fortunately, three years later, Waiting for Jack turns out a best-seller on Amazon!
We all have a “Jack” for whom we wait—whether it’s a person, a place or a thing. Now I would like to ask you: what are you waiting for?
【1】From the first paragraph we can learn that the author_________.
A．wanted Jack to autograph her book
B．wanted to be as successful as Jack
C．wanted to make friends with Jack

C．The importance of taking action to achieve a goal.
D．The harm of blindly worshipping others as heroes.
24、 There are as many different types of sleeper as there are animal varieties on the planet. There are dozers, dreamers, nappers and hardcore dead-to-the-worlders.
Dolphins
Dolphins face a bit of a problem as they spend their whole lives in the water, but as mammals they need to breathe oxygen to survive. How do they juggle this when unconscious? Dolphins shut down half of their brain, which rests, while the other half is alert and looking out for any potential dangers. As they do this, the dolphin will lie on the surface of the water in a behaviour known as “logging”.
Elephants
Elephants tend to nod off for a few minutes at a time throughout the day. Elephants only manage about two hours of sleep per day, and that’s not even a concentrated block of shuteye. They tend to nod off for a few minutes at a time throughout the day. Possibly because of this, most of their sleeping is done standing up, with just the occasional recumbent sleep.
Spiders
Of course spiders have to be awkward. Even though animals sleep in a vast array of different ways, all of them, even bacteria, follow a 24 hour cycle, known as a circadian rhythm that is dictated by the rotation of the Earth. But scientists have discovered that certain types of orb-weaving spiders simply don’t bother with this. Their body clocks follow a 17, 18 or 19 hour cycle. Scientists aren’t exactly sure how the spider can even exist with this completely different body clock.
Koalas
One problem with trying to work out a creature’s sleeping habits is the difficulty of identifying what is actual sleep. It’s easier to study captive animals, but they can behave in a completely different manner to their cousins in the wild. Koalas studied in zoos were thought to sleep for up to 22 hours a day, but a more detailed study, looking at animals in the wild too, revealed that they in fact sleep for around 14 hours a day plus a healthy amount of resting on top of that. Their diet of eucalyptus leaves takes a lot of time and energy to digest.
Frogs
Frogs are incredible. They have managed to master practically every environment on the planet, no matter how hot or how cold. They not only use hibernation in winter as a sleep strategy, they also engage in something called estivation, where they reach a dormant state during the summer months to avoid overly hot or dry conditions. Despite all this knowledge, scientists aren’t sure exactly how frogs sleep during the months when they are active.
【1】Which animal sleeps the longest hours a day according to the passage?
A．The dolphin.
B．The koala.
C．The spider.
D．The elephant.
【2】What is still confusing to scientists?
A．How they can identify what is actual sleep.
B．How dolphins breathe oxygen when sleeping.
C．How spiders can survive a different body clock.
D．How frogs sleep when they are not hibernating or estivating.
【3】What is the passage mainly about?
A．Why animals sleep differently.
B．What animals do while sleeping.
C．The extraordinary ways that animals sleep.
D．The mystery about different types of sleeper.
