21、Death is natural, but do you have any idea of the process of dying? Modern scientists divide the process of dying into two phases --- clinical or temporary death and biological death. Clinical death occurs when the vital organs, such as the heart or lungs, have ceased to function, but have not suffered permanent damage. The organism can still be revived(复活). Biological death occurs when changes in the organism lead to the “breaking up” of vital cells and tissues. Death is then unchangeable and final.
Scientists have been seeking a way to prolong the period of clinical death so that the organism can remain alive before biological death occurs. The best method developed so far involves cooling of the organism, combined with narcotic sleep. By slowing down the body’s metabolism(新陈代谢), cooling delays the processes leading to biological death.
To illustrate how this works, scientists performed an experiment on a six-year-old female monkey called Keta. The scientist put Keta to sleep with a narcotic. Then they surrounded her body with ice-bags and began checking her body temperature. When it had dropped to 28 degrees the scientists began draining blood from an artery. The monkey’s blood pressure decreased and an hour later both the heart and breathing stopped: clinical death set in. For twenty minutes Keta remained in this state. Her temperature dropped to 22 degrees. At this point the scientists pumped blood into an artery in the direction of the heart and started artificial breathing. After two minutes Keta’s heart became active once more. After fifteen minutes, spontaneous(自发的)breathing began, and after four hours Keta opened her eyes and lifted her head. After six hours, when the scientists tried to give her a penicillin injection, Keta seized the syringe and ran with it around the room. Her behavior differed little from that of a healthy animal.
【1】For a person who suffers from the clinical death, _________.
A. his most important organs are damaged.
B. he still has the possibility of getting back to life.
C. he cannot avoid final death.
D. he is still very much alive
【2】Scientists try to make the time of clinical death longer in order to __________.
A. slow down the body’s metabolism.
B. bring vital cells and tissues back to active life.
C. cool the organism.
D. delay the coming of biological death.
【3】How did the scientists put Keta into clinical death?
A. By putting her to sleep, lowering her temperature and draining her blood.
B. By surrounding her body with ice-bags and draining her blood.
C. By lowing her blood pressure and stopping her heart from beating.
D. By draining her blood, lowering her blood pressure and stopping her breathing.
【4】All of the following indicate that the monkey has almost restored to her original physical state except the fact that__________.
A. her heart beat again.
B. she regained her normal breath.
C. she rejected a penicillin injection.
D. she acted as lively as a healthy monkey.
22、Two high school students have identified four new planets in distant space about 200-light-years from Earth, making them “the youngest astronomers” to make such a discovery.
Kartik Pingle, 16, and Jasmine Wright, 18, who both attend schools in Massachusetts, participated in the Student Research Mentoring Program (SRMP). With the help of Tansu Daylan, an MIT doctor for Astrophysics and Space Research, the students studied and analyzed data from the Transiting Exoplanet Survey Satellite (TESS). Together they focused on Tess Object of Interest (TOI) 1233, a nearby, bright sun-like star and here they found four planets rotating (旋转) around the star. “We were looking to see changes in light over time,” Pingle explained, “the idea is that if the planet transits the star, or passes in front of it, it would periodically cover up the star and decrease its brightness.”
While studying 1233, Pingle and Wright had at least hoped to find one planet, but were overwhelmed with joy when a total of four were spotted. “I was very excited and very shocked.” Wright said. “We knew this was the goal of Daylan's research, but to actually find a multi-planetary system, and be part of the discovering team, was really cool."
Three of the newly discovered planets are considered as “sub-Neptunes”, which are gaseous (气态的), but smaller than the Neptune that lives in our solar system. While observing the planets, the team determined each one completes their orbit around 1233 every six to 19.5 days. However, the fourth planet is labeled a “super-Earth” for its large size and rockiness---this one orbits around the star in just under four days.
“We have long been studying planets beyond our solar system and with multi-planetary systems, the two young students are kind of hitting the jackpot. They are really blessed.” Daylan said, “The planets originated from the same disk of matter around the same star, but they ended up being different planets with different atmospheres and different climates due to their different orbits. So, we would like to understand the fundamental processes of planet formation and evolution using this planetary system.”
Daylan added that it was a “win-win" to work with Pingle and Wright on the study. “As a researcher, I really enjoy interacting with young brains that are open to experimentation and learning and have minimal bias.” he said, “I also think it is very beneficial to high school students, since they get exposure to cutting-edge research and this prepares them quickly for a research career.”
【1】How did the two students identify the four planets?
A．By helping professor Tansu Daylan with the data.
B．By analyzing the change of brightness of star 1233.
C．By studying Neptune that lives in our solar system.
D．By interacting with other young talented brains.
【2】What is special about the discovery?
A．It was made by two high school students.
B．It was made with an innovative approach.
C．It was meant to be made by Tansu Daylan.
D．It found the largest number of planets at a time.
【3】Which of the following is closest in meaning to “hitting the jackpot” in paragraph 5?
A．Making a discovery difficultly.
B．Achieving the goal easily.
C．Succeeding in something luckily.
D．Performing a task carefully.
【4】According to the article, what benefits does the study bring?
A．It allows the scientists to work with young people without prejudice.
B．It equips future astronomers with better researching capabilities.
C．It provides more perspectives and thus boosts more discoveries.
D．It arouses students’ interest in exploring the unknown universe.
23、Best National Parks in America
Olympic National Park
Visitors have been enjoying Olympic National Park since 1938. The majority of this mostly unspoiled wonder is undisturbed and undeveloped, making it ideal for camping and wilderness exploration. Snow-based activities are popular in the winter, while visitors enjoy exploring its woodland areas and long shoreline (海岸线) throughout the other three seasons. Olympic National Park, which includes more than 4,000 square kilometers of the Olympic Peninsula in the northeast corner of Washington state, protects a rich mix of natural and cultural heritage.
Channel Islands National Park
The Channel Islands, rich in history and long in ocean miles, provide a unique opportunity for ocean, land, and history enthusiasts. Fans of the sea will enjoy relaxing on beaches, diving and sailing between the islands. Land lovers will enjoy great hiking options on all six islands, as well as one permanent camping on each. History lovers will enjoy learning about the park’s nearly 13,000 years of human history.
Canyonlands National Park
Canyonlands National Park is located in southeastern Utah and is famous for 527 square miles of beautiful desert landscape formation that has resulted in many canyons, ephemeral pools, and buttes by the Colorado River and its network of rivers and streams. Water erosion (侵蚀) has been the important architect of the beautiful landscape that attracts hikers and families who travel to see its breathtaking sunset and experience the great outdoors.

24、 If you asked people to name a famous psychology study, the “marshmallow (棉花糖) test” would probably come out near the top of the list. In this task, young children are told they can immediately get one marshmallow or wait to get two marshmallows. Researchers have shown that the ability to wait is associated with a range of positive life outcomes more than a decade later.
A new study published recently expands on this earlier research and shows that young children will wait nearly twice as long for a reward if they are told their teacher will find out how long they wait.
For their study, Heyman, the lead author on the study, and her colleagues conducted two experiments with a total of 273 children aged 3-4 years old. The researchers told the children that they could earn a small reward immediately or wait for a bigger one. Children were assigned to one of three conditions: a “teacher” condition, in which they were told that their teacher would find out how long they wait; a “peer” condition, in which they were told that a classmate would find out how long they wait; or a “standard” condition that had no special instructions.
Children waited longer in the teacher and peer condition than in the standard condition, and they waited about twice as long in the teacher condition as in the peer condition. The researchers were surprised at that because the traditional view is that 3- and 4-year-olds are too young to care about what other people think of them.
“The children waited longer even though no one directly told them that it’s good to wait longer,” said Heyman. “We believe that children are good at making these kinds of inferences because they pay close attention to what people around them value. This may take the form of carefully listening to the evaluative (评价性的) comments that parents and teachers make, or noticing what kinds of people and topics are getting attention in the media.”
【1】Why does the writer mention the “classic marshmallow test” in the beginning?
A.Because it is the basis of the new study.
B.Because it is the most famous psychology test.
C.Because it influences children’s life outcomes.
D.Because it reveals the link between wait and lifestyles.
【2】What does Paragraph 3 mainly explain about the experiments?
A.The process. B.The purpose. C.The preparations. D.The results.
【3】How did the researchers feel about the findings according to the text?
A.Unexpected. B.Disappointed. C.Overjoyed. D.Doubtful.
【4】What might be the conclusion of the experiments?
A.Bigger rewards motivate human behavior.
B.The awareness of comments from others starts earlier.
C.Young children have a stronger desire to impress others.
D.The older children are, the better they control themselves.
