21、What does an outdoor cat do all day? A study of more than 900 house cats shows when they kill small birds and mammals, their influence is concentrated in a small area, having a bigger effect than wild predators (捕食性动物) do.
Roland Kays, a scientist at North Carolina State University and his colleagues collected GPS data from cats in six countries. “These cats are moving around their own backyard and a couple of their neighbors’ backyards, but most of them are not ranging very much further,” Kays said. “So initially I thought, ‘Oh, this is good news. They’re not going out into the nature preserves. ’ ”
Then Kays took how much wildlife cats kill in that small area into consideration. Some cats in the study were bringing home up to 11 dead birds a month, which doesn’t include what they ate or didn’t bring home.
“It actually ends up being a really high rate of predation,” Kays said. He calculates that cats can have 4to10 times the influence of a wild predator. Native predators, like jungle cats, also kill a lot of small animals, but their influence is spread out over a larger area. One study indicates that house cats kill billions of birds every year.
“The simplest thing to do is to keep your cat indoors,” Kays said.
For those who refuse to keep their cats inside, there are potential options. St. Lawrence University’s associate professor Susan Willson looked for one. She found a special brightly colored collar online.“The whole idea is that the bird will be able to visually see the cat creeping (爬行) up on it before the cat attacks it,” she said. Willson tested the collar on both her cat and dozens of others. It greatly reduced the number of birds the cats brought home.
“I’m not saying these collars can make a significant difference in the massive bird death that we’re seeing,” she said. “But what matters is that each individual bird that somebody finds in his backyard is not dead.”
【1】Why does Kays say “this is good news” in Paragraph 2？
A．House cats can be tracked by GPS.
B．House cats are protected from wild predators.
C．House cats won’t kill birds in large numbers.
D．House cats feel comfortable in their own backyard.
【2】How do wild predators differ from house cats in terms of killing animals?
A．They prefer to attack larger animals.
B．Their victims are distributed in a bigger range.
C．They kill 4－10 times the number of house cats.
D．They kill less than house cats on a monthly basis.
【3】What can we infer from the passage?
A．The colored collar can be a sign of potential danger to birds.
B．Willson considers keeping her cat inside a good idea.
C．The only way to protect birds is to keep them indoors.
D．Birds can’t sense the danger when cats attack them.
【4】Which word can best describe Willson’s attitude to using collars to save birds?
A．Concerned.
B．Indifferent.
C．Doubtful.
D．Positive.
22、The famous scientist Stephen Hawking spoke at a science festival in Norway in 2017, “We are running out of space and the only places to go to are other worlds... Spreading out may be the only thing that saves us from ourselves. I’m convinced that humans need to leave Earth.”
Hawking was not alone in this view. Many experts feel that the only way for humanity to last far into the future is to colonize (移民于) other planets. That way, if a terrible disease, nuclear war or some other disaster strikes Earth, civilization as we know it would still have a chance. Mars is one of the most attractive destinations. NASA, the United Arab Emirates, the private company SpaceX, and the organization Mars One all have plans to send humans there. “Either we spread Earth to other planets, or we risk going extinct,” SpaceX founder Elon Musk said at a conference in 2013.
But not everyone agrees that colonizing Mars or any other planet is such a great plan. The most common argument against going is that it’s just too expensive or dangerous. It will take huge amounts of money and other resources just to get people there, let alone set up a place for them to live. It’s not even clear if humans could survive on Mars. One of the biggest dangers there is deadly radiation that ruins the planet.
Maybe all the time and money people would pour into a Mars mission would be better spent on more urgent projects here on Earth, like dealing with poverty or climate change. Some experts argue that handling a problem like an asteroid (小行星) strike or disease outbreak while staying here on Earth would be much easier and less expensive than surviving on a new planet.
In addition, moving to a new planet could harm or destroy anything that already lives there. Mars seems uninhabited, but it could possibly host micro-organism like. Human visitors may destroy this life or permanently change or damage the Martian environment. Some feel that’s too much of a risk to take.
【1】Why did the author mention NASA, the United Arab Emirates, SpaceX and Mars One?
A．To stress the risk of dying out on Earth.
B．To provide evidence for Hawking’s theory.
C．To show growing intention of moving to Mars.
D．To explain the advanced technology in astronomy.
【2】What can we learn from the passage?
A．Civilization is difficult to maintain on Earth.
B．It is costly and risky to colonize Mars.
C．Poverty is the most urgent problem to handle.
D．All the time and money should be spent on Earth.
【3】What does the underlined word “uninhabited” mean in the last paragraph?
A．Not fit to live on.
B．Not steady to keep.
C．Not easy to approach.
D．Not safe to set foot on.
【4】Which of the following can be the best title for the text?
A．Mars, Our Future Planet
B．Moving to A New Planet
C．Should We Colonize Mars?
D．Stay Home or Outer Space?

24、Elon Musk is a businessman, inventor and engineer and is undoubtedly, one of the leading figures in the world of technology. Musk was born in Pretoria, South Africa in 1971. At the age of 12, he taught himself how to programme computers. He was accepted to university in the United States where he completed a degree in Arts. After this, he started a PhD in physics at Stanford University. However, he dropped out to pursue his interest in startups and technology.
He founded an online payment site that eventually would become a global company. In 2001 Musk began meeting with scientists to discuss the possibility of human habitation on Mars. Using his own fortune, Musk founded his company that designs rockets and space vehicles. It was the first privately owned company to do so. In 2012, the rockets made by the company docked with the International Space Station. Musk also received contracts from NASA, thus making history by proving that the concept of commercial space exploration was both possible and affordable.
Another one of Musk’s innovations is the electric car. Musk started a company and became the CEO in 2008. The company is named after Nicolai Tesla, the Serbian-American inventor and physicist, who is best known for designing the AC electrical system. The cars made by Musk’s company are designed to end the dependence on fossil fuels and so reduce the negative effects of climate change and air pollution from cars.
Why does Musk devote himself to such innovations? By creating opportunities to explore new planets, Musk believes that in the event of a major catastrophe on Earth, there would be the potential for the human race to continue elsewhere. On Earth, Musk’s inventions are designed to find renewable, environment-friendly solutions to meet the challenge of an ever-growing global population.
