Forest of a Thousand Lanterns by Julie C. Dao
The first book in the Rise of the Empress series takes the bones of a traditional fairy tale — a poor girl fated for power, an evil queen determined to stop her, love for someone who doesn't love back and magic — and
gives them a richly imagined East Asian setting. Dune

If the Star Wars movies have made you fall in love with the space opera, eventually you're going to read Frank Herbert's most famous creation. The story of centuries-old political plotting — about warring factions
(派系) battling over control of the extremely valuable planet Arrakis — is a classic and remains a wonderful introduction to the larger, more complex world of science fiction just beyond the Star Wars trilogies.

As a kid, Joanna Buckley wasn’t interested in science — until she had a chance to try it. That happened when she got a chemistry set for Christmas.
“Over the course of a few weeks, I’d completed every experiment. But in the process, I polluted my parent’s dining room carpet and burnt the kitchen worktop with the spirit burner,” she says.
Now science is Buckley’s job. She works in the chemistry department at the University of Sheffield in England. “I realize, first-hand, how important it is to have something or someone to show you why science is so great,” she says. Now the good news is that citizen science appears. Citizen science takes the fun of experimenting a step further than Buckley’s at-home chemistry kit. That’s because these experiments are real, looking for novel answers.
“Compared with a one-off experiment, what’s cool about citizen science is that students get that this has a purpose,” says Prunuske，who teaches microbiology and immunology at a medical college . “Students want to do a good job, because they know scientists are going to use the new data in their own research.”
Jennifer Long’s job is to coordinate(协调) education and outreach. She agrees with Prunuske. “Kids like that it’s real. And they like that it’s important, that it matters.” Citizen-science projects have made big discoveries. One found a previously unknown galaxy cluster （星系团）. Another project helped assess how much damage a big earthquake had caused in Japan. And one of the first citizen-science projects helped scientists learn where Monarch butterflies go every winter.
Some adults worry about teens losing interest in science. That’s one reason they hope that fun, exciting citizen-science projects can help them keep engaged, Long says. And she has some evidence that it’s working, “Last year, we did have a couple of students say, ‘I really think I want to be a scientist now. ” 24. What is the purpose of paragraph 2?
A. To support trials can make teens interested in science. B. To prove failure is the mother of success in science. C. To state Buckley has a talent for science. D. To praise Buckley for her strong will. 25. Why is citizen science more fun?
A. It needs to seek for new solutions.
B. It carries out experiments frequently. C. It must carry out experiments in groups. D. It demands to handle complex problems. 26. What can we know from what Prunuske said? A. She participated in the experiment. B. She took pride in what students took up. C. Citizen science is popular with students. D. Scientists are willing to employ students. 27. What is Long’s attitude towards citizen science?
A. Concerned. B. Supportive. C. Doubtful. D. Unclear.

Your circle of friends may help you get a better reading on your overall health and wellness rather than just using wearable devices such as a Fitbit, according to researchers. The study, published in the journal PLOS ONE, analyzed what the structure of social networks says about the state of health, happiness and stress.
\拓扑学) of the social network — what does my position within my social network predict about my health and well-being said Nitesh V. Chawla, a professor at the University of Notre Dame in the US.
“What we found was the social network structure provides a significant improvement in predictability of wellness states of an individual over just using the data obtained from wearables, like the number of steps or heart rate,” Chawla said.
For the study, participants wore a Fitbit to capture health behavior data about walking, sleeping, heart rate and overall activity level. They also completed surveys and self-assessments of their stress, happiness and positivity.
Cbawla and his team then analyzed the data with a machine learning model, alongside the connections and characteristics of an individual's social network.
The study showed a strong correlation (相关性) between social network structures, heart rate, number of steps and level of activity.
Social network structure provided significant improvement in predicting one's health and well-being compared to just looking at health behavior data from the Fitbit alone.
For example, when social network structure is combined with the data from wearables, the machine learning model achieved a 65 percent improvement in predicting happiness.
The model also achieved a 54 percent improvement in predicting one's self-assessed health prediction, a 55 percent improvement in predicting positive attitude and a 38 percent improvement in predicting success.
This study asserts (断言) that without social network information, we only have an incomplete view of an individual's wellness state, and to be fully predictive or to be able to obtain interventions (干扰). It is critical to be aware of the social network, Chawla said. 28. What did the study find?
A. How people choose their friend circles. B. What factors decide your friend circles. C. How your circle of friends influences you D. What your circle of friends says about your health. 29. How did the researchers draw their conclusions?
A. By comparing data. B. By giving examples. C. By analyzing cause and effect D. By describing personal experiences.
30. What does the underlined word “critical” mean in the last paragraph?
A. Easy. B. Common. C. Important. D. Challenging. 31. What do Chawla's words in the last paragraph tell us? A How fitness devices can connect your circle of friends B. That a person's social network is part of his health picture. C. The best ways to make friends and keep a healthy social circle
