Babies’ Look Changing
Researchers show that the early social behavior called look changing is linked to babies’ ability to learn new language sounds. 1.. It is when a baby makes eye contact and then looks at the same object that the other person is looking at.
Rechel Brooks, one of the researchers, made a report, showing that babies’ look changing serves as a building block（基础）for more complicated language and social skills. 2..
In this experiment, nine 5-month-old babies from English-speaking families attended foreign language tutoring sessions. Over four weeks, the tutors talked and played with toys while speaking Spanish.
At the beginning and end of the four-week period, researchers counted how often the babies changed their look. 3.. There they tested how much Spanish language sounds.
4.. The more look changing the babies participate in during their tutoring sessions, the greater their brain response were to the Spanish language sounds.
“Our findings show young babies’ social engagement contributes to their own language learning – they’re not just passive listeners of language,” Brooks said. “They’re paying attention and showing parents they’re ready to learn when they’re looking back and forth.” 5..
The researchers hope their findings help people develop strategies for teaching young children.
A.That’s when the most learning happens
B.These skills are what preschool children can gain
C.The results were really amazing
D.We can’t imagine how look changing helps them learn so much
E.However, others may regard look changing as something useless
F.Look changing is one of the earliest social skills that babies show
G.After the experiment ended, the researchers brought the babies back to the lab
PCs are no longer the only things that can be hacked（非法侵入）. Anything with an electronic pulse, including cars, TVs and refrigerators, is now a target for hackers. Here are several strangest hacks that show where the future is headed:
Remote-controlling a car – Well-known security researcher Charlie Miller is able to control a car by accessing the automotive computer. In 2011, a security company figured out how to unlock a car and start it just by texting and back in 2010, someone hacked into100 cars in Texas, causing them to honk（鸣响）uncontrollably before he remotely disabled them.
Cyber Murder – In Season 2 of Show Time’s homeland series, hackers kill the US Vice President by hacking his pacemaker（心脏起搏器）. Typical Hollywood B. S., right? No. It could actually happen. Well-known security researcher Barnaby Jack, who sadly passed away in July at the age of 35, had been prepared to demonstrate at Back Hat how to hack a pacemaker over Wi-Fi. The attack could kill a person by giving the pacemaker a high-voltage shock.
Spy Phone – By now, more people are becoming aware of the potential for a phone to be hacked. But what many fail to realize is the awesome potential of a smart phone to affect you, it has been hacked.
When Your TV Watches You – This type of hack makes it possible to monitor people in their homes via the internet. Smart TVs aren’t that common yet, but in the next few years they could become an important part of the living room, so watch out.
1.The main purpose of this text is to ________.

Examining the classroom practices of National Teacher of the Year winners and finalists, the study, by Michigan State University scholars, suggests successful educators aren’t afraid to push the boundaries by adding real world, cross-disciplinary（跨学科的）themes into their lessons.
The study, published online in the journal Teachers College Record, is one of the first in depth investigations of how teachers use creativity in the classroom.
“The best teachers are taking their own creative interests – from rap music to cooking to kickboxing – and are finding ways to include these into the curriculum,” said Danah Henriksen, lead author of the study. “They’re bringing together different subject matters and finding areas of connections so students can learn both in interesting ways.”
America’s test-driven educational policy, Henriksen argues, has impeded creativity in teaching and learning. Many teachers today struggle to balance high-stakes（高风险）testing and responsibility to act flexibly and independently in their classrooms.
“I think that there’s a lot of fear.” one of the award-winning teachers says in the study, “And when teachers are teaching in fear, they take few risks, for they have to consider exams and academic performance.”
The findings have major implications（含意）for teaching and learning. Teachers’ unique creative interests should be brought into classroom lessons, along with arts and music across varied academic content. Teacher education programs and professiona1 development courses should include a focus on real world. Administrators and policymakers should support opportunities for teachers to take creative and intellectua1 risks in their work.
“If we want teachers to be creative, we need to provide them with opportunities to bring those outside interests into their professional life,” said Mishra, study co-author and MSU professor of educational psychology and educational technology. “The point is to find what works for you, what is your passion and interest and how can you put that into what your students are learning. Finally, we teach who we are. That’s the most powerful finding.”
1.According to the study, what are successful teachers like?
A.They can creatively help students learn about the real world.
B.They concentrate on developing students’ academic performance.
C.They encourage students to take more risks in life.
D.They tend to lead students to outdoor activities.
2.What does the underlined word “impeded” in paragraph 4 mean?
A.admitted.
B.prevented.
C.doubted.
D.encouraged.
3.Many teachers are teaching in fear because ________.
A.they don’t want to take risks in classroom
B.the students are always troublesome
C.administrators and policymakers don’t support them
D.they’re worried about students’ academic records
4.What would be the best title of the text?
A.American perfect teaching system
B.How teachers use creativity in the classroom
C.A great finding: Best teachers get creative
D.Teaching is about science and art
Brown bears have stopped eating salmon（鲑鱼）in favor of elderberries after being forced to make a choice due to climate change. Warming temperatures mean that the berries are ripening earlier than usual, at exactly the same time as the freshwater streams on Alaska’s Kodiak Island are over flowing with salmon.
The island’s brown bears typically feed first on salmon in early summer, followed by elderberries later in the season, in late August and September.
“What you have is a scrambling of the schedule,” said William Deacy, a biologist at Oregon State University that studied the phenomenon.
“It’s essentially like if breakfast and lunch were served at the same time and then there is nothing to eat until dinner. You have to choose between breakfast and lunch because you can only eat so much at a time.”
The study found that during the unusually warm summer of 2014, the bears, which would traditionally kill up to 75 percent of the salmon, were nowhere to be seen near the streams. Instead, they were in the hills busy munching on berries, which contain less protein and therefore take less energy to break down, causing them to gain weight more quickly.
Biologists warned that changes caused by a warming planet were behind the bears’ unusual behavior and could affect the entire ecosystem.
The researchers found that the forests around the streams suffered because the bears’ fish carcasses（残骸）were no longer there to enrich the soil.
“Bears switched from eating salmon to elderberries, disturbing an ecological link that typically fertilizes the ecosystems and generates high death rates for salmon,” the study said. On average, red elderberries are said to be ripening two and a half days earlier every decade. If the pattern continues, they will regularly overlap（重叠）with the salmon by 2070.
1.Brown bears have begun to favor ________ because of the climate change.
A.salmon
B.elderberries
C.warm temperatures
D.fresh water
2.What does William Deacy mean by saying the underlined sentence?
A.Brown bears eat their breakfast and lunch at the same time.
B.We’re facing a hard problem with choosing the meals.
C.Climate change is disturbing the bears’ eating habits.
D.People’s biological clocks are changing regularly.
3.Which of the following words can best describe the phenomenon?
A.Natural. B.Unusual.
C.Amazing. D.Typical.
4.The finding of the study shows us that ________.
A.brown bears may become bigger and bigger
B.there will be a higher death rate for the salmon
C.red elderberries will probably be ripening in summer
D.the changes of bears’ behavior could affect the entire ecosystem
