A
Daniella Wride was brushing her daughter’s long brown hair when she noticed that with each comb, masses of the hair were coming out. That was January 1, 2017. Within 20 days, seven-year-old Gianessa Wride’s hair was completely gone, and her doctor said the hair would never grow back. Gianessa had become one of the 6.8 million Americans with alopecia, an auto-immune disease that causes hair loss.
Alopecia isn’t painful, but for kids who suffer from it, the severe pain comes from standing out from the crowd. For the most part, the students in Gianessa’s first-grade class in Salem, Utah, were understanding. But the occasional jokes of “Baldy” (秃子) made her feel like an abandoned child. “I didn’t want her to feel that she wasn’t like the other kids,” her mother said. “I tried covering her baldness, but the artificial hair was uncomfortable.”
B. A youth project.
C.
School
B. Passers-by.
C.
Airplane
Then comes the school’s traditional “Crazy Hair Day” in April, a great just-for-fun celebration where all the kids and their parents can express their wild sides a bit. Daniella and Gianessa decided that rather than hide Gianessa’s baldness under the artificial hair, they would celebrate it. Daniella bought scrapbook-sticker (贴纸) jewels and decorated her head with flowered designs and even a deer. “They just fit her personality,” Daniella smiled. “She’s so lovely.”
On the morning of the competition, Gianessa was nervous. Would her friends think it was funny? However, with her mother’s encouragement, she had nothing to fear. Impressive Gianessa was a hit and a winner of the crazy-hair competition. Gianessa is now glad that she dared to go bare. “I was sad at first when I lost all my hair,” she told people. “But now I love being bald. I can do things to my head that other kids can’t. I’m thinking now it might be fun to decorate my head with some colourful butterflies and flowers.” 21. Why was Gianessa different from other kids? A. She was born bald.
B. She suffered from hair loss. D. She had her head fully shaved.
C. She was talented in hair designing.
22. How did others react to Gianessa’s disease? A. Her doctor was quite optimistic.
B. Her mother gave her artificial hair. D. Her school offered her special help.
C. Her classmates were all considerate.
23. What could Gianessa do on the “Crazy Hair Day”？ A. She could tease others.
B. She could decorate her hair. D. She could show her personality.
C. She could shop scrapbook-stickers. 24. What is the main idea of the text?
A. The artificial hair built up the girl’s confidence. B. The girl faced her disease in a most beautiful way. C. The competition served as a way to make a change. D. The disease was cured with mother’s love and care.

A study has shown that severe stress lasting weeks or months can damage cell communications in the brain’s memory areas. Recently, researchers from University of California, Irvine, have provided the first evidence that short-term stress lasting for a few hours has the same effect.
“Stress does exist in our lives and cannot be avoided,” said Dr. Baram, leader of the UC Irvine School. “Our findings can play an important role in the present development of medicine that might prevent these undesirable effects and offer understanding of why some people are forgetful or have difficulty keeping the memories.”
In their study, Baram and her UC Irvine colleagues identified a novel process in which stress caused these effects. They found that, severe stress activated (激活) Corticotropin Releasing Hormones (CRH), which prevented the brain from keeping memory.
Memory takes place at synapses, where there are connections through which brain cells communicate. These synapses lie on dendritic spines (神经元). In rat and mouse studies, Baram’s group saw that the release (释放) of CRH in the brain’s primary memory center led to the rapid breakup of these dendritic spines, which in turn limited the ability of synapses to collect and store memories.
In addition, the researchers reproduced the effects of stress on dendritic spines by keeping low levels of CRH, and watching how the spines ruptured over minutes. “Fortunately, once we removed the CRH, the spines seemed to grow back again, ‘‘Baram said. “And this study can play a role in the creation of treatments to address stress-related memory loss.” 25. According to the text, short-term stress can lead to . A. memory loss C. head damage
B. cell decrease D. thought disorder
26. The underlined word “ruptured” in Paragraph 5 is closest in meaning to . A. came into being away
27. What is the author’s purpose of writing the text? A. To discuss the main stages of stress. B. To show the primary cause of stress. C. To introduce a new finding about stress. D. To promote an effective treatment for stress.
