21、It’s almost spring, the time of year when the change in seasons could lead to some pretty fascinating cloud activity in the sky. NASA and the GLOBE Program are inviting you to take part in a citizen science cloud observation challenge. The GLOBE Program is an international science and education program that provides students and the public with the opportunity to participate in data collection and the scientific process.
From March 15 through April 15, citizen scientists of all ages can make up to 10 cloud observations per day using the GLOBE Observer app or one of the other data entry options (for trained GLOBE members). Challenge participants with the most observations will be congratulated by a NASA scientist in a video posted on the GLOBE Program’s website and on social media.
“The GLOBE Program is offering this challenge to show people how important it is to NASA to have citizen scientist observations: observations from the ground up,” said Marile Colon Robles, lead for the GLOBE Clouds team at NASA’s Langley Research Center in Hampton, Virginia. “We’re going from winter to spring, so the types of storms will change, which will also change the types of clouds.
Researchers use, and value, this citizen science cloud data because it helps to validate data from Earth-observing instruments. Scientists at Langley work with a set of six instruments known as the Clouds and the Earth’s Radiant Energy System(CERES)
Even though CERES’ instruments use advanced technology, it is not always easy for researchers to positively identify all types of clouds in their images. For example, it can be difficult to differ thin, wispy cirrus clouds(细小的卷云)from snow since both are cold and bright; even more so when cirrus clouds are above a surface with patchy snow(片状雪)or snow cover. One solution to this problem is to look at satellite images from a particular area and compare them to data submitted by citizen scientists on the ground.
“Looking at what an observer recorded as clouds and looking at their surface observations really helps us better understand the images that were matched from the satellite,” said Colon Robles.
You don’t have to be a cloud-gazing professional to participate. For those who want to be part of the challenge but don’t have a lot of experience identifying clouds, Colon Robles offers the following advice: “Just go outside.” The more clouds you observe, she said, the more comfortable you’ll be collecting data.
【1】Why do researchers launch the cloud observation challenge?
A．The GLOBE Program is badly short of hands.
B．The technology CERES uses is not that advanced
C．Scientists can compare data from different instruments.
D．Cirrus clouds are difficult to identify when with snow cover
【2】The underlined word “validate” is closest in meaning to _________.
A．create
B．cancel
C．count
D．confirm
【3】Which of the following is TRUE?
A．Citizen observers can only submit their data by means of an app
B．Observers submitting the most observations can get a special prize
C．Observations from the ground are not as valuable as satellite images
D．The data collected by citizen scientists will be posted on social media
【4】Which is the best title for the passage?
A．NASA Employs New members
B．Cloud Activities Bring a New Challenge
C．Citizens Gain Experience through Observation
D．Professionals Teach You to Observe Clouds
22、 After three quarters of an hour they reached the height where the hut（小屋）of the old man stood on a rock, exposed to every wind, but bathed in the full sunlight. From there you could see far down into the valley.
Overlooking the valley the old man had made himself a bench, by the side of the hut. Here he sat, with his pipe between his teeth and both his hands resting on his knees. He quietly watched the children climbing up with the goats and Aunt Deta behind them. Heidi reached the top first, and approaching the old man, she held out her hand to him and said, “Good evening, grandfather！”
“Well, well, what does that mean?” replied the old man in a rough voice. Giving her his hand for only a moment, he watched with a long and penetrating（穿透性的）look from under his bushy brows. Heidi gazed back at him and examined him, for he was strange to look at.
Deta had arrived in the meantime with Peter, who was eager to see what was going to happen.
“Good-day to you, uncle,” said Deta as she approached. “This is Tobias’s and Adelheid’s child. You won’t be able to remember her, because last time you saw her, she was only a year old.”
“Why do you bring her here?” asked the uncle, and turning to Peter, he said: “Get away and bring my goats. How late you are already！”
Peter obeyed and disappeared; the old man had looked at him in such a manner that he was glad to go.
“Uncle, I’ve brought the little girl for you to keep,” said Deta. “I have done my share these four years and now it’s your turn to provide for her.”

23、A snow leopard（雪豹）research team said one of its infrared（红外的）cameras caught some snow leopards playing in a national park in the east end of the Qilian Mountains, which the team leader said is “of great significance”.
There have been suspected sightings of snow leopards in east Qinghai before, but none has ever been confirmed.
The snow leopard, often found near the alpine snowline in the Asian heartland, has been called “the king of snow mountains”. It is a Class-A protected animal in China and is classified as “vulnerable” by the International Union for Conservation of Nature.
“Based on these images, we can conclude that the area has a certain number of snow leopards, but the exact population is yet to be calculated,” said Ulgi, an official at the reserve.
In fact, in the snow leopard project, a number of high-tech equipment have been increasingly used in monitoring and protecting the species, such as infrared cameras, drones（无人机）and DNA research based on the animal’s excrement（排泄物）. “Still, more should be done to protect the snow leopard, which is vulnerable to challenges such as climate change, habitat loss and human activities,” he said.
A total of 60 infrared cameras have been scattered across the largest State-owned forest in the central and eastern Tianshan Mountains, covering an area of around 550 square kilometers, according to sources in charge of the project on February 18.
“We will keep monitoring to learn more about snow leopard activities in the Tianshan Mountains and assist the local administration to come up with more targeted protection measures,” said He Bing, snow leopard project manager.
He said that the discoveries of snow leopards and other animals in China were evidence of China’s increased efforts in environmental control, such as the protection of natural forests.
【1】How were the snow leopards exactly discovered?
A．Caught on camera.
B．Seen by local people.
C．Followed by the team.
D．Watched from the drone.
【2】What does the underlined word “vulnerable” in paragraph 5 probably mean?
A．Hardly available.
B．Easily hurt.
C．Changeable.
D．Valuable.
【3】What can we expect of the snow leopard protection in the future?
A．The infrared cameras will be replaced by handy cameras.
B．The project will soon be successfully finished.
C．More high-tech equipment will be made use of.
D．Monitoring places will be transferred to other areas.
【4】Which of the following can be the best title for the text?
A．Countries Unite to Protect Snow Leopards
B．The King of Snow Mountains Is Worthy of the Name
C．The Infrared Cameras Play an Important Role in Animal Protection
D．Snow Leopards Are Spotted in China’s Qilian Mountains
