Have you ever seen your cat or dog eating grass? They do so because it can help their digestion, and many wild species use natural substances to prevent and control diseases. This is called"zoopharmacognosy"or, more commonly, animal self-medication.
Scientists have discovered that tamarin monkeys use a specific tree resin (树脂) as medicine. In the Brazilian Atlantic Forest, scientists followed several groups of them to collect data. During one of these daily studies, tamarin monkeys were observed rubbing their bodies on the trunk of a tree. At first, researchers thought that they were marking their territory, a common behaviour in this species. Botanical experts later confirmed that the tree was a species of cabreúva, which is well known for its medical properties.
Researchers decided to place camera-traps in different sites at the foot of the tree to record future visits by tamarin monkeys. The records surprisingly showed that many animals living in the forest visited it. Totally, ten species were observed. For many of them, it was the first time that behaviors similar to self-medication had been observed. More surprisingly, one species spread resin on each other's fur in pairs. In general, the species seemed to specifically visit the tree to acquire the resin and seemingly benefit from it, either healing their wounds or fighting back parasites(寄生虫).
While further studies are needed to identify the properties of the resin and thus confirm that this is indeed self-medication, the use of it suggests that cabreúva represents a common and universal drugstore for the residents of the Brazilian Atlantic Forest. It is likely to be a valuable resource helping the species maintain their magnitude by improving their health.
This discovery could have an important protection influence, as the disappearance of some trees could potentially affect the survival of some animals.
(1)、Why do tamarin monkeys rub themselves against the tree?A、They are trying to cure diseases. B、They would like to digest what they eat. C、They feel like occupying the land. D、They are attracting companions' attention.(2)、What do researchers find through camera-traps?A、Many animals copy monkeys'behaviors. B、Animals can help each other clean the fur. C、The cabreúva is the habitat of tamarin monkeys. D、Resin can be used as medicine for some animals.(3)、What does the underlined word"magnitude"in paragraph 4 probably mean?A、Populations. B、Characteristics. C、Similarities. D、Flexibilities.(4)、What is the possible significance of the discovery?A、Promoting evolution of creatures. B、Increasing the production of resin. C、Contributing to forest conservation. D、Motivating the study of monkeys' diet. -

FORT WORTH, Texas—— If 14-year-old Ruhani Ahluwalia had her way, her days would be filled with time to let her curiosity run free. How can a doctor attack cancer with medicines that don't damage the patient? How can an artist touch a person with a hidden message in an oil painting?This is Ruhani's world —where the pursuit of learning leads to more learning for a self-described Renaissance teenager, who is multi-talented and has interests.
Since age 11, she has been working summers in a lab at the University of North Texas Health Science Center researching cancer cells. She is testing drugs that can kill cancer cells while limiting the side effects on health y cells. It's a special mission guided by the heart because she lost a great aunt to leukemia(白血病) when she was in the sixth grade.
"What really damaged her eventually was the treatment and the side effects of it, which kills both cancer and normal cells. "Ruhani explained. Due to this, Ruhani started her cancer research. "I wanted to find a better way to target cancer cells. "
During the summer between sixth and seventh grade, Ruhani began research in the study of cancer with the help of her mother, Parmeet Jodhka, a microbiology professor, who taught her daughter the necessary biology. Working from about 10 a. m. to 3 p. m. in the lab, she has finally presented her findings at multiple science fairs. Her list of accomplishments is five pages long and includes placing third in Brazil's science fair, MOSTRATEC, for her breast cancer research.
"I like learning. "She said. "There is a difference between learning and studying. Studying, you are too stuck in finishing it and in turning it in. Learning, you are doing more for yourself. "
(1)、What is Ruhani's research aimed at?A、Testing how the cancer cells work. B、Saving her great aunt from leukemia. C、Relieving the pain of cancerous persons. D、Protecting healthy cells in cancer treatment.(2)、What is paragraph4 mainly about?A、Rouhani's summer vacation. B、Participants at the science fairs. C、Lessons taught by Parmeet Jodhka. D、The tireless efforts on the research.(3)、What can be inferred from the last paragraph?.A、Learning is the eye of the mind for all. B、Learning is more difficult than studying. C、Learning is too much of a burden to bear. D、Learning is a means of self-improvement.(4)、Which is the most suitable title for the text?A、A Girl's Lasting Pursuit of Learning B、New Birth of a Young Professor C、Success of a Well-rounded Teenager D、Stimulation of Students"Curiosity -

14、 第二节 读后续写阅读下面材料,根据其内容和所给段落开头语续写两段,使之构成一篇完整的短文。
Elizabeth walked to the yard, carrying a bunch of daisies (雏菊).
"Beautiful flowers for, for… Oh, I'll never get it right!" she cried, throwing the daisies on the ground. She had been practising her speech for a week.
Part of her couldn't wait. This Saturday, the great Ana Wolff, famous pianist, would perform at the concert hall in town. For four years, Elizabeth had listened to Ms Wolffs recordings over and over again, loving the way the notes flowed like a rushing mountain stream.
Part of Elizabeth was terrified. Her music teacher at school, Mr. Leaf, had asked her to present the flowers to Ms Wolff after the performance. But Elizabeth knew herself well. She had severe stage fright and she really hated it when she had to talk in front of people. Even so, Elizabeth was determined to take the challenge this time.
"How's the speech going?" asked Elizabeth's mother. "Want to practice on me?"
"No, thanks." said Elizabeth. "Mum, I can't do this! I'll forget. I might even pass out!"
"Oh, honey. Think about it… sharing the stage with Ana Wolff. What an honour!" Mum gently comforted her.
Elizabeth kept practising. "Beautiful flowers for… for a beautiful performance…" She presented the flowers to the cat, the dog, even the statue in the garden.
Soon it was Saturday night, Elizabeth stood at the backstage, behind the heavy black curtains. Holding the bouquet (花束) of red roses, she felt her heart racing wildly and her stomach tightened with nervousness.
The lights dimmed, and Ms Wolff began her performance. She swayed and nodded with her fingers dancing across the keys. Soft sad parts, loud angry parts, parts that sounded fun to play. Drawn into the music, Elizabeth forgot for a moment about the six words she had to say. With a flourish, Ms Wolff played her final note. Applause thundered through the hall. People jumped to their feet and cheered. Ms. Wolff smiled and bowed. Then she walked off stage and into the wings. Almost immediately, she returned to the stage for a second bow.
注意:1. 续写词数应为150左右;2. 请按如下格式在答题卡的相应位置作答。
Then came the dreaded moment.
The audience cheered and clapped loudly for them.

18、 根据短文内容,从短文后的选项中选出能填入空白处的最佳选项。选项中有两项为多余选项。
Good gift giving is an art. The perfect present can lift a mood or improve a relationship. So are there any rules to follow? Read on for 4 essential tips.
·Don't add a small gift to a big gift.
Want to add a tie to an expensive shirt? Some flowers to go with a bottle of grand wine? Don't. When we receive several gifts together, we tend to average out their value.
·Gift experiences rather than things.
A new iPhone becomes old fast. Often more thought has gone into experiences, and they create more vivid memories. That is why you should consider an experience over a physical object while gifting.
·Gift cards are not bad.
Gift giving can be wasteful. We only spend $10 on ourselves if we find something that we expect is worth more than 10 to us. But gift is different, because we're not buying for ourselves. So we can spend 10 on something that's worth less than 10 to the receiver. Gift cards have become much more popular over time. And they're also very popular with receivers — a better option than a rushed or poorly chosen gift that goes straight to the garbage can.
Let's put it very simply: buy things that your receiver would buy for themselves. That might seem obvious, but it happens far less than we'd like. People tend to use gifts to signal something about themselves rather than providing utility (实用) or happiness to the receiver. The best way to get it right is to simply ask the question—"What would you like?"
A. Think like the receiver.
B. It could even be worth nothing to them.
C. Use gifts to signal something about yourself.
D. But having the same experience strengthens bonds.
E. Therefore, a small gift added to a big one will hurt the big one's impact.
F. Whatever the occasion, gift giving requires careful thought and consideration.
G. But a dream vacation or seeing your favorite artist will give you memories that last forever.

19、 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。
Three years into my postdoc (博士后), I started to wonder whether I needed a new career plan. After applying for more than two dozen teaching jobs, I hadn't landed a single interview.
I had once considered going to art school but had put that idea to the side when I decided to pursue chemistry as an undergraduate. In the years that followed, I kept up my interest in art by taking painting classes at night. My family was bursting with mathematicians, computer programmers, and engineers, so it felt natural to have my daily life center around science.
But in the spring after my failed job search, that started to change after a friend excitedly showed me proofs of a review article. She was astonished by what the journal's scientific illustrator had done with her fundamental sketches (速写). "That would be such a fun job." I thought.
I decided to test out a new career direction by volunteering to create similar illustrations for my institute's newsletters. I spent my nights and weekends reading scientific papers and thinking about how to illustrate the results. It was a fun task. I felt I was perhaps on the right path. But could I make a full-time career work?
Searching online, I tracked down people who had that kind of job. I found many had training through scientific illustration master's degree programs. After living on graduate student and postdoctoral salaries for years, I didn't have enough money saved up for the programs, so I decided to get a certificate in digital design.
I now work as a visual designer at a biomedical research institute where I spend my days working with research to communicate their work visually. I love the fact that I get to combine my scientific and artistic sides.
(1)、Why did the author attend classes at night?A、To please her family. B、To pursue her hobby. C、To pass her undergraduate tests. D、To complete optional courses in art.(2)、What effect did the proofs have on the author?A、They shook her belief in science. B、They tested out what she learned in class. C、They motivated her to find a new career direction. D、They gave her inspiration for her scientific paper.(3)、What prevented the author seeking a scientific illustration master's degree?A、Her financial difficulties. B、Her busy schedule. C、Her new interest in digital design. D、Her lack of confidence.(4)、How does the author feel about her current job?A、Pressured. B、Curious. C、Desperate. D、Satisfied. -
20、 阅读下列短文,从每题所给的A、B、C和D四个选项中,选出最佳选项。
When you're super tired, you may be more likely to take a nap than grab a snack. What about mosquitoes? Scientists have long been interested in mosquito sleep cycles.
However, it's hard to study sleeping mosquitoes. That's partly because mosquitoes will get excited when they sense a meal: the experimenter. That makes it difficult for the insects to nod off (打盹). And when mosquitoes do nod off, they look rather similar to those that are just resting to save energy.
Ajayi at the University of Cincinnati and his colleagues studied mosquitoes' sleep. The team focused on three species known to carry diseases. The first, Aedes aegypti, is active by day. The second, Culex pipiens, prefers to dine after dusk. The third, the malaria — carrying Anopheles stephensi — is up at night. All these mosquitoes were left alone in a room. There, the team used cameras and sensors to spy on them. Together, these observations helped the researchers spot a sleeping mosquito.
After about two hours, the mosquitoes appeared to nod off. They didn't move for a long time. And as time went on, Culex pipiens and Aedes aegypti showed less response when the experimenter walked in the room. This showed that a tasty smell was less likely to wake those species when in a deep sleep.
Then the insects were placed in clear tubes that were shaken every few minutes to keep them from falling into a deep sleep. After 4 to 12 hours, the team exposed the insects to some heated sweat. That mimicked (模仿) the presence of a host on which the mosquitoes could snack. In another experiment, a human volunteer offered up a leg for mosquitoes to feed on for five minutes.
In both cases, the mosquitoes that got a full night's rest were much more likely to land on the host than sleep-deprived (剥夺) ones. In eight tests, an average of 77 percent of the well-rested mosquitoes went for a blood meal. Only 23 percent of mosquitoes that were sleepy did the same.
"The findings open avenues for research into controlling mosquitoes." Ajayi says. "That, in turn, could help keep people safe from mosquito-spread diseases."
(1)、What adds difficulty to studying sleeping mosquitoes?A、Mosquitoes' daily routines. B、The smell of human beings. C、The wide variety of mosquitoes. D、Mosquitoes' different sleeping habits.(2)、What did Ajayi do to study mosquitoes?A、He tracked mosquitoes' behavior. B、He tested the mosquitoes on his leg. C、He went over many previous studies. D、He exposed mosquitoes to many snacks.(3)、What is the finding of the study?A、Mosquitoes need more sleep than humans. B、Mosquitoes never bite when lacking sleep. C、Sleepy mosquitoes like the smell of heated sweat. D、Sleepy mosquitoes are more likely to sleep than to eat.(4)、What is the significance of this study?A、It can help to understand human sleep. B、It can help to control the spread of some diseases. C、It can help to to find out technology to mimic mosquitoes. D、It can help to discover the differences between various mosquitoes.
