Part Three高考题型强化练

Have you ever noticed that the stars sometimes appear brighter in December, January and February? There’s a link between cold air and the night lights. “Part of the reason is that it tends to be drier in the winter,” said Diane Turnshek, an astronomer at Carnegie Mellon University in Pittsburgh, Pennsylvania. Even though it’s invisible, moisture (水分) can change the way light moves through the air. And in the summer, moisture can make stars appear more dull.
Air temperature is also what puts the twinkle in the little stars. “Even on very clear nights, some of the atmosphere is cooler, and some of the atmosphere is warmer,” said Turnshek, who also works with the Allegheny Observatory. And when the light from a star passes through those bubbles of varying temperatures, they bend and shift the light, so that we are seeing stars appear to dance or twinkle, she said.
For star lovers in the United States, there’s another factor that comes into play for bright winter stars, although this is a matter of coincidence. During Earth’s journey around the sun, “there are just simply more bright stars visible from the Northern Hemisphere in the winter sky,” Turnshek said. If you really want to see a shiny star, just try to find a burning ball of gas called Sirius near the horizon. At 8.6 light years away, Sirius is relatively close to Earth and the brightest star visible in the night sky. It is also large—nearly twice as big as our sun and 20 times as bright as it. So this winter, when the world turns cold and it seems like we should be spending more time indoors, consider asking an adult to go exploring outside. With a warm coat and a clear sky, any night can be turned into a treasure hunt. All you have to do is look up.
1. What does the underlined word “dull” in Paragraph 1 probably mean?
A. not shiny B. not exciting C. not severe D. not smart
2. How does air temperature influence the brightness of stars?
A. By changing the bubbles around them.
B. By putting the twinkle in them.
C. By varying the direction of the light from them.
D. By making the stars dance and twinkle in the sky.
3. What do we know about Sirius?
A. It can be found at any night.
B. It is 20 times as bright as the sun.
C. It is a burning and dull ball.
D. It is closer to Earth than other stars.
4. What is the author’s purpose in writing the text?
A. To advocate stargazing in winter.
B. To call on people to focus on stars.
C. To present new research results about stars.
D. To explain why stars are more visible in winter.

A 293-million-mile journey of the NASA Perseverance rover (探测器)to Mars ended successfully on February 18, 2021, with a picture-perfect landing inside the Jezero Crater. The car-sized, six-wheeled rover, nicknamed Percy, is the US space agency’s biggest and most advanced explorer to date. Its primary mission is to search for signs of ancient microbial (微生物的) life on Mars.
Landing on Mars is extremely tricky. The Red Planet’s gravitational(引力的) pull causes approaching spacecraft to go faster to high speeds，while its thin atmosphere—just 1 percent that of Earth’s—does little to help slow it down as it approaches the surface.
The scientists had to reduce Percy’s 12,000 mph speed to a safe landing speed of less than five mph—in just six and a half minutes. The target entry angle also had to be a precise 12 degrees—any steeper, and the spacecraft would burn up; any flatter, and it would get lost in space. It is no wonder that the final approach is often referred to as the “seven minutes of terror”.
Upon attaining a manageable speed, Percy briefly flew over the Martian surface to seek out the perfect landing spot. Its complex map-reading system rapidly scanned the area and matched it with maps in its database to find the best location.
The NASA scientists will spend the next two months testing Percy’s scientific instruments. Once ready, the rover will begin to carry out its mission.
“Perseverance is the smartest robot ever made, but confirming that microbial life once existed carries an unusually large burden of proof,” said Lori Glaze, director of NASA’s Planetary Science Division. “While we’ll learn a lot with the great instruments we have aboard the rover, it may very well require the far more well-equipped laboratories and delicate instruments back here on Earth to tell us whether our samples (样本) carry evidence that Mars once harbored life.”
5. What is the extraordinary challenge for the rover to land on Mars?
A. The speed reduction.
B. The atmosphere analysis.
C. The location search.
D. The time management.
6. What is Paragraph 3 mainly about?
A. Ways to find the precise entry angle.
B. Consequences of wrong entry degree.
C. Factors to survive “the seven minutes”.
D. Reasons for the necessity of speed reducing.
7. What does “it” refer to in Paragraph 4?
A. The spot. B. The area. C. The system. D. The surface.
8. What can be inferred from Lori Glaze’s words?
A. Instruments aboard the rover are not quite reliable.
B. Perseverance is able to collect enough evidence needed.
C. Man still has a long way to go to prove life was on Mars.
D. Samples of Mars will be returned soon to our labs on the Earth.
