21、 Beatrice Finkelstein, as chief of the Food Technology Section of the Life Support Systems Laboratory at Wright Patterson Air Force Base, bore responsibility for managing the nutritional needs of the astronauts. Her work in the field of space feeding was important in developing the equipment and techniques used in early space flight. Few, if any, female contributors played as important a role as she did during the early years of the U. S. crewed space program, and she deserves to be better remembered.
Finkelstein’s value to America’s space tasks went well beyond her technical contributions. She was frequently described in the popular press at the time as “the Nutritionist to the Astronauts”, as well as the proprietor or of “Bea’s Diner”, a restaurant designed to appeal to the public as a very friendly place.
In her role as nutritionist for the early space program, Finkelstein grew to know the astronauts well, as she communicated with them frequently. At times, she would step beyond her formal role as nutritionist, providing emotional and psychological support to the astronauts. On many occasions, she was one of the last people the astronauts communicated with before launch (发射), and there’s a lot of evidence that shows her friendship was a source of comfort during the stressful pre-launch activities.
The image of nutritionist Beatrice Finkelstein showed that the agencies that insured NASA’s successful space flights were staffed by smart women as well as smart men. Her role in America’s success in conquering space in the technical field of space feeding served as an example of the role women could and did play in the early space program.
【1】Why does Beatrice Finkelstein deserve to be remembered?
A．She was a really great astronaut.
B．Her astronaut team made significant achievements.
C．She bore responsibility for early space flight.
D．Her feeding work was vital in early space flight.
【2】What does the underlined word “proprietor” in Paragraph 2 mean?
A．Tutor.
B．Editor.
C．Owner.
D．Engineer.
【3】What can we infer about Beatrice Finkelstein from Paragraph 3?
A．She was also a psychologist.
B．She relieved astronauts’ pressure.
C．She communicated with astronauts after launch.
D．She cooked much nutritious food for astronauts.
【4】What is the best title for the text?
A．One Special Nutritionist
B．A Great Space Astronaut
C．The First Woman Astronaut
D．The Most Popular Nutritionist
22、 Mammals (哺乳动物) tend to get huge when they invade the ocean. Why? Most of the explanations for this trend treat the ocean as a kind of release. The water partly frees mammals from gravity, allowing them to evolve heavy bodies. But to William Gearty from Stanford University, the ocean makes mammals so big not because it relieves them of limits, but because it sets new ones.
"To deal with the constant loss of heat as you get into the water, the easiest way is to get bigger." he explains, "As bodies balloon, volume increases faster than surface area does, so you produce more heat in your body but lose comparatively less of it from your skin."
But there is a limit because larger bodies also demand more fuel, and there's only so much food that an animal can reasonably get. Therefore, the need to stay warm sets a floor for the body size, while the need to eat sets a ceiling. And the gap between them, Gearty found, is surprisingly narrow. "The minimum size of oceanic mammals is thousands of times larger than the minimum for mammals on land, but the maximum size is only 25 times larger," says Gearty.
These trends suggest that the water places strict size limits. Oceanic mammals must be just the right size-big, yes, but not too big and not too small.
And as always in biology, there are exceptions. Whales go way beyond the size limit. Nick Pyenson from the Smithsonian Institution thinks he knows why. Around 3 million years ago, a combination of changes to glaciers (冰川), winds, and currents created a large increase of nutrients in coastal waters, which then fed lots of shrimps and small fish-potential prey (猎物) for whales.
But these bonanzas weren't evenly distributed. Instead, they were concentrated in particular places far apart from each other-all-you-can-eat buffets separated by food deserts. And that Pyenson says, is why the giant whales evolved. They are adapted to hunt down concentrated prey. Their huge size allows them to survive for a long distance without encountering any food. And they evolved a special technique of feeding. The existence of concentrated prey, and the evolution of a technique for capturing them, allowed whales to break the size ceiling. That's why they transformed from big animals into the biggest animals that ever existed.
【1】William Gearty's explanation differ from traditional ones because he believes _________.
A．bigness helps mammals to survive in the water
B．the ocean puts size limits on oceanic mammals
C．oceanic mammals are larger than mammals on land
D．gravity prevents mammals from evolving heavy bodies
【2】We can learn from the passage that _________.
A．the sea mammals have to get as big as they can to hunt for food
B．the need to stay warm decides the size ceiling of oceanic mammals
C．the maximum size of an oceanic mammal depends on its food supply
D．the smallest mammals in the ocean are 25 times as big as those on land
【3】The underlined word "bonanzas" in the last paragraph probably refers to _________.
A．buffets and deserts
B．shrimps and small fish
C．glaciers and currents
D．nutrients and waters
【4】What is the purpose of the passage?
A．To emphasize the importance of big size for the whale.
B．To introduce how whales evolve to survive in the ocean.
C．To explain what influences the sizes of oceanic mammals.
D．To appeal for more scientific studies on oceanic mammals.
23、How to Get Rid of Study Stress
Do you find yourself feeling stressed and overwhelmed when studying for quizzes, tests, or final exams? This is a common problem among many young people, whether they are in junior high or college. However, there are many tricks that can be used to avoid being stressed about studying for school. 【1】
Whether you are taking a college course on psychology or a driver’s education class, it is important to pay close attention to what your instructor is saying. Typically, if the teacher repeats themselves or writes something on the board, it is important to understand and remember. 【2】
An important part of preventing distraction is by taking concise(简明的), clear notes in class.【3】 Write down things you do not clearly understand or cannot remember. Use graphs, diagrams, and arrows to thoroughly explain concepts. This will help you understand lectures and will reduce study stress at a later time.
If you find yourself not understanding a concept and the text is not making it clear to you, ask questions. 【4】 If you do not understand something, your studying will be confusing and help you very little. If the teacher mentions something in class, do not be afraid to raise your hand and ask if they can explain it further. Better yet, talk to your teacher after school to get some one-on-one time so that you feel confident about your comprehension of a topic.
【5】 Getting adequate sleep allows the mind to store concepts and topics so that you can remember and understand them. Get enough sleep the night before an exam. This should be no problem, since you won't be cramming!
A. Try to make it to every class, and take notes to keep yourself from being distracted during the lecture.
B. Getting ahead on reading the material will ensure that you understand it (or at least some of it).
C. Rest is actually vastly important for your mind to retain information.
D. Write down things the teacher repeats or writes on the board.
E. Set aside thirty minutes every evening to repeat what you learned in class that day.
F. Here are some effective ways to reduce your own study stress.
G. You must ask questions in order to have stress-free studying.
24、Alone on a barren island, Ding Peng and his colleagues bring the Chinese crested tern (凤头燕鸥) back from the edge of extinction. From time to time, Ding Peng makes his way across the waves to Zhongtiedun, an island that dots the vast East China Sea.
Born in Lanzhou, capital of Northwest China’s Gansu Province, Ding grew up seeing bare mountains and sandstorms, and had an early awareness of environmental protection.
In March 2013, Ding landed on Zhongtiedun with more than 30 experts to choose a breeding (繁育) area for Chinese crested terns. They wanted to restore their populations through manual intervention (人工干预).
At the beginning, there were no Chinese crested terns on Zhongtiedun and Ding’s first cask was to attract the birds to settle there. Their breeding period is usually from May to August, and they like to lay their eggs on small islands with little tree cover, so Ding and the team of experts settled on relatively flat Zhongtiedun. They also cut away the taller bushes, while 400 fake birds of the same size as Chinese crested terns were placed there, with a bird sound playback system installed to simulate the sound of courtship (求偶).
However, they were unable to attract any of the birds over the following two months. “The experts suggested withdrawing the equipment and making plans for the next year,” Ding recalls. Ding proposed the equipment that had been installed on the island not be taken down. Two days later, the team got what they wished for—several Chinese crested terns were found among the group of great crested terns flying in the sky.
“Though the life on the island is tough, things took a turn for the better in 2017, when more volunteers came to join the bird protection team. Everything was worth it. Now that more people are aware of the importance of protecting the birds, and now that their numbers are on the rise,” Ding says.
【1】What do we know about Ding?
A．He is from a poor family.
B．He is an environmentalist.
C．He lives in mountains now.
D．He feels lonely on the island.
【2】Why did Ding and the team of experts cut away the taller bushes?
A．To install fake birds more conveniently.
B．To make the birds’ vision much clearer.
C．To observe Chinese crested terns closely.
D．To create a better breeding environment for the birds.
【3】What does Ding think of his work?
A．It is very worthwhile to do it.
B．It still has a long way to go.
C．It is the most important project.
D．It has strengthened his willpower.
【4】How does the text develop?
A．By showing examples.
B．By giving some quotes.
C．By following time order.
D．By making comparisons.

26、阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
The excitement about Thanksgiving was really building. Grandma arrived with a homemade pecan pie. Dad was searching for his electric carving knife. Mama was in the kitchen humming a song. Little baby Lonnie bounced up and down. Dad smelled the air and sighed. My big brother, Slim, who was anything but slim, sneaked off to his room with a slice of the pecan pie. Even our dog Fido was wagging his tail.
Having set a pretty table, Mama looked up, smiling. “Help me carry in the food,” she said. Slim, who had come out of his room by this time, went racing into the kitchen. " I'll get it! I'll get it!” The rest of us piled in behind him, everyone grabbing a dish. Then we watched Dad carry in the biggest, brownest, best-smelling turkey we had ever seen with Mama's hand under the plate, just in case. Together they lowered the turkey to its place at the table.
It was the tradition in our family to think of something for which we were most thankful. We all ran to the table yelling something like “I'm thankful for school being out” or “I'm thankful for pecan pie!” All eyes were on that enormous turkey as we took our seats.
Yes, everything was perfect except for one thing. On that special day, it was Dad who sat at the head of the table and carved the turkey. It was an honor that he had eagerly expected for days. Mama always called Dad a clumsy ox. He frequently tripped (绊倒) over his own two feet, and he could drop just about anything.
We automatically eased back when Dad tested the electric carving knife in the air. Dad went to work on the white meat first with surprisingly few problems. Slice after slice landed neatly on the plate with thick gravy (肉汁)。Dad leaned forward and grabbed the end of the left turkey leg and cut it off, placing it whole on the plate. His oily fingers shone brightly in the light of the chandelier (大吊灯)，and Mama waved her napkin. “I'm all right, Mama,” he said. “I'm all right. ”
