Questions 26 to 35 are based on the following passage.
Surfing the Internet during class doesn't just steal focus from the educator; it also hurts students who're already
struggling to 26 the material. A new study from Michigan State University, though, argues that all
students—including high achievers—see a decline in performance when they browse the Internet during class for
non-academic purposes.
To measure the effects of Internet- based distractions during class, researchers 27 500 students taking an
introductory psychology class at Michigan State University. Researchers used ACT scores as a measure of intellectual
28 . Because previous research has shown that people with high intellectual abilities are better at 29 out
distractions, researchers believed students with high ACT scores would not show a 30 decrease in performance due
to their use of digital devices. But students who surfed the web during class did worse on their exams regardless of their
ACT scores, suggesting that even the academically smartest students are harmed when they're distracted in class.
College professors are increasingly 31 alarm bells about the effects smartphones, laptops, and tablets have on
academic performance. One 2013 study of college students found that 80% of students use their phones or laptops during
class, with the average student checking their digital device 11 times in a 32 class. A quarter of students report that
their use of digital devices during class causes their grades to 33 .
Professors sometimes implement policies designed to 34 students' use of digital devices, and some instructors
even confiscate (没收) tablets and phones. In a world where people are increasingly dependent on their phones, though,
such strategies often fail. One international study found that 84% of people say they couldn't go a day without their
smartphones. Until students are able to 35 the pull of social networking, texting, and endlessly surfing the web,
they may continue to struggle in their classes.

A)aptitude I）obscure
B)eradication J)obsess

D)evaporated L）resist
E)filtering M）significant
F)grasp N) suffer
G)legacy O）typical
H) minimize

A Pioneering Woman of Science Re-Emerges after 300 Years

[A] Maria Sibylla Merian, like many European women of the 17th century, stayed busy managing a household and
rearing children. But on top of that, Merian, a German-born woman who lived in the Netherlands, also managed a
successful career as an artist, botanist, naturalist and entomologist （昆虫学家）.
[B] “She was a scientist on the level with a lot of people we spend a lot of time talking about,” said Kay Etheridge, a
biologist at Gettysburg College in Pennsylvania who has been studying the scientific history of Merian’s work. “She didn't
do as much to change biology as Charles Darwin, but she was significant.”
[C] At a time when natural history was a valuable tool for discovery, Merian discovered facts about plants and insects
that were not previously known. Her observations helped dismiss the popular belief that insects spontaneously emerged
from mud. The knowledge she collected over decades didn't just satisfy those curious about nature, but also provided
valuable insights into medicine and science. She was the first to bring together insects and their habitats, including food
they ate, into a single ecological composition.
[D] After years of pleasing a fascinated audience across Europe with books of detailed descriptions and life-size
paintings of familiar insects, in 1699 she sailed with her daughter nearly 5,000 miles from the Netherlands to South America
to study insects in the jungles of what is now known as Suriname. She was 52 years old. The result was her masterpiece,
Metamorphosis Insectorum Surinamensium.
[E] In her work, she revealed a side of nature so exotic, dramatic and valuable to Europeans of the time that she
received much acclaim. But a century later, her findings came under scientific criticism. Shoddy （粗糙的）reproductions of
her work along with setbacks to women's roles in 18th- and 19th- century Europe resulted in her efforts being largely
forgotten. “It was kind of stunning when she sort of dropped off into oblivion （遗忘）,” said Dr. Etheridge. “Victorians
started putting women in a box, and they're still trying to crawl out of it.”
[F] Today, the pioneering woman of the sciences has re-emerged. In recent years, feminists, historians and artists have
all praised Merian's tenacity （坚韧）, talent and inspirational artistic compositions. And now biologists like Dr. Etheridge
