Find a quiet location. Keep a routine. Focus on one subject at a time. It all seems like sound advice for students who need to hit the books, 1. . Here’s a list of tips from Carey, a scientist, for getting the most out of your study time:
2.
Doing practice quizzes can help you retrieve（检索）information on test day. “Tests have a very bad reputation as a measurement tool,” Carey says. But psychologists have found self-tests slow down the forgetting of material you’ve studied. “If you study something once, and then you test yourself on it,” Carey says, “you do better than if you study it twice over.”
Move around
3. . “If you move around and study the same material in several places,” he says, “you may be forming multiple associations for the same material. So it’s better anchored in your brain, and you can pull it out easier.”
Mix it up
Think about a football who does strength training, speed training and drills. Carey says alternating between different facets facts of a subject in a single sitting can “leave a deeper impression on the brain”. For example, when studying French, do some verbs, some speaking and some reading. 4. .
Space it out
Information learned in a hurry is lost just as fast. So if you really want to learn, space out shorter, hour-long study sessions. “There’s no doubt that you can cram for（突击备考）an exam.” Carey says, “5. . And once it’s gone, “it’s gone. You’re not getting it back.”
A. Test yourself
B. Study it and practice more
C. and it turns out that some of them are in great help
D. but recent studies indicate the conventional wisdom is wrong
E. The problem is that it’s so easy to forget what you just crammed
F. Changing up where you study can help you keep more information
G. Spending your time in deep concentration on just verbs isn’t effective
Some people dream about becoming engineers, Luckily, the new IMAX film Dream Big shows how engineering can improve people’s lives. It teaches viewers how engineers use high-tech to help the world. The film hits IMAX theaters nationwide on February 17 to celebrate Engineers Week.
The film, taking place in locations like China, Dubai and Africa, tells the stories of engineers who try to come up with creative ideas to save energy and help people.
Dream Big was directed by Greg MacGillivray who has 38 films under his belt, including some of the most successful films ever shown in IMAX theaters.
How did MacGillivray get into the moviemaking business? “I grew up at the beach. My first movies were about surfing and the ocean. As time went on, I saw the changes in the ocean including polluting and overfishing. So I started making films about conservation of nature.” He told TFK. Now, his films cover a variety of topics, from the natural world to human creation.
One of the engineers in Dream Big is Angelica Hernandez. In high school, she was on a team that best MIT, a university, in an underwater robotics competition. Today, the engineering work she does focuses on helping people use less energy and save money and resources. “I work with companies to promote energy efficiency with their commercial customers, so it’s really trying to push forward all the measures that customers and high-energy users can apply, she explains.
Engineering is such a good job-you make good money, travel around the world, solve amazing problems and help people.” She says.
The mission of Dream Big is to show people the good that engineers can do to the world. “That was the impulse of making this movie”, MacGillivray explains, “We want to explain engineering in a way that will get the kids very excited about it.” “Whoever and wherever you are, you can become an engineer,” he adds, “All you need is the creative spirit.”

Humans’ invention of zero was vital for modern mathematics and science, but we’re not the only species to consider “nothing” a number. Parrots and monkeys understand the concept of zero, and now bees have joined the club, too.
Honey bees are known to have some numerical skills such as the ability to count to four, which may come in handy when keeping track of landmarks in their environment. To see whether these abilities extended to understanding zero, researchers trained 10 bees to identify the smaller of two numbers. Across a series of trials, they showed the insects two different pictures displaying a few black shapes on a white background. If the bees flew to the picture with the smaller number of shapes, they were given delicious sugar water, but if they flew toward the larger number, they were punished with bitter-tasting food.
Once the bees had learned to consistently make the correct choice, the researchers gave them a new choice: a white background containing no shapes at all. Even though the bees had never seen an empty picture before, 64% of the time they chose it rather than a picture containing two or three shapes, the authors report today in Science. This suggests that the insects understood that “zero” is less than two or three. And they weren’t just going for the empty picture because it was new and interesting. Another group of bees trained to always choose the larger number tended to pick the nonzero image in this test.
In further experiments, the researchers showed that bees’ understanding of zero was even more complex: for example, they were able to distinguish between one and zero-a challenge even for some other members of the zero club. Advanced numerical abilities like this could give animals an evolutionary advantage, helping them keep track of predators（捕食者）and food sources. And if an insect can display such a thorough grasp of the number zero, write the researchers, then this ability may be more common in the animal kingdom than we think.
1.According to the trials, the researchers have found that bees ________.
A. have the same intelligence as parrots and monkeys
B. can count many numbers after being trained
C. can identify the smaller number quickly
D. understand the concept of zero
2.The researchers trained another group of bees to ________ .
A. confirm the bees are able to identify the smaller number
B. find the big difference between the two groups of bees
C. prove the bees are interested in new things
D. show the bees can be distinguished easily
3.What do the researchers suggest in further experiments?
A. Bees should be trained more.
B. Numerical abilities could help predators find bees.
C. Insects are better at understanding zero than animals.
D. Animals may display a thorough grasp of the number zero.
4.What is the best the title for the text?
A. New Findings About Bees’ Concept of Zero
B. Experients on Bees’ Numerical Skills
C. Complex Trials About the Zero Club
D. A Science Report of the Species of Bees
In 2012 my wife and I decided to open our bookstore in spite of unfavorable situations. The challenges facing small bookstores were-and remain-significant. Apart from the obvious rise in online selling, the increase in the popularity of e-books has negatively affected independent providers.
The question is why a new, small-scale（小规模的）provide would voluntarily enter such a challenging market? From a personal view, our reasoning was sound: we wanted to share our love of great books and reading for pleasure with as many like-minded people as possible.
Having done our homework, one thing became clear. In order for us to succeed, we would have to offer something that none of our larger competitors already provided. And so we started the Willoughby Book Club. We set up our website in the summer of 2012, and we haven’t looked back.
The idea of service is simple. We offer a range of book subscription gift packages, available in three-month, six-month and 12-month options. Our customers choose a package, tell us a little about the person they’re buying it for, and we use this information to send the receiver a hand-picked, gift-wrapped book once a month. We also recently decided to give one new book to Book Aid International for every gift subscription sold. These books are sent out to sub-Saharan Africa, supporting the educational work there. Within four months of starting out, we won the Young Bookseller of the Year Award at the 2013 Bookseller awards.
Our brief journey from new booksellers to award receivers has been challenging and rewarding. The biggest thing we’ve learned is that, despite the pressures facing independent providers, there is a place for them in the UK market. It’s just a question of finding it.
1.What challenges do the couple have to face when opening their bookstore?
A. Their bookstore is in an unfavourable place.
B. They are short of money and manpower.
C. Their books tore has limited great books.
D. Online selling and e-books are gaining popularity.
2.What does the underlined word “sound” in Paragraph 2 mean?
A. accurate B. controversial
C. reliable D. safe
3.In order to succeed, the couple have taken practical measures except ________ .
A. setting up a book club
B. building their website
C. sending the customers gifts every month
D. aiding some Africans by giving them new boos
4.What’s the author’s opinion on being an independent provider?
A. It is anything but challenging.
B. It is difficult but worth it.
C. It is too difficult to succeed.
D. It is just a question.
