How to Study Smarter, Not Harder
Here are some of our favorite study tips that will help any student study smarter, not harder:
Recite As You Study
Reciting—saying things out loud should first take place as you read through each paragraph or section. Test yourself. This will help you to understand as well as learn faster because it is more active than reading or listening. It will also help you to notice your mistakes and the topics you have trouble understanding.
Take Fuller Notes
Notes should be in your own words, brief and clear. They should be tidy and easy to read. Writing notes will help you better than just underlining as you read, since it forces you to rewrite ideas in your own words.
Study the Middle
The best time to review is soon after you’ve learned something. You are more likely to remember the material at the beginning and the end of the lesson, so make sure you focus on the middle when you review.
Sleep On It
Study before going to bed, unless you are very tired. It’s easier to remember material you’ve just learned after sleeping than after an equal period of daytime activity, because your brain continues to think even after you’ve fallen asleep.
Combine Memory and Understanding
There are two ways to remember: by memorizing and by understanding. Multiplication tables, telephone numbers, and math formulas are better learned by rote. Ideas are best learned by understanding.
The more ways you have to think about an idea, the more meaning it will have; the more meaningful the learning, the better you can remember it. Pay attention to similarities in ideas and concepts, and then try to understand how they fit in with things you already know. Never be satisfied with anything less than a completely clear understanding of what you are reading. If you are not able to follow the thought, go back to the place where you first got confused and try again. You can notice your mistakes by _______.
| A．saying things out aloud | B．taking notes |
| C．studying the middle | D．sleeping on it |
When taking notes, you should _______ to better help you with reading.
| A．underline important notes |
| B．write notes in your own words |
| C．take down every detail |
| D．write as quickly as possible |
The writer advises you to _______ as it is easier for you to remember material.
| A．study after a period of activity |
| B．do some exercise after studying |
| C．study as soon as you get up |
| D．study before going to sleep |
Which of the following is NOT helpful for your understanding?
| A．Thinking about an idea in different ways. |
| B．Relating ideas and concepts with what you already know. |
| C．Reading from the beginning to the end without stop. |
| D．Going back to what first made you confused and start again. |

By the end of the century, if not sooner, the world's oceans will be bluer and greener thanks to a warming climate, according to a new study.
At the heart of the phenomenon lie tiny marine microorganisms (海洋微生物) called phytoplankton. Because of the way light reflects off the organisms, these phytoplankton create colourful patterns at the ocean surface. Ocean colour varies from green to blue, depending on the type and concentration of phytoplankton. Climate change will fuel the growth of phytoplankton in some areas, while reducing it in other spots, leading to changes in the ocean's appearance.
Phytoplankton live at the ocean surface, where they pull carbon dioxide (二氧化碳) into the ocean while giving off oxygen. When these organisms die, they bury carbon in the deep ocean, an important process that helps to regulate the global climate. But phytoplankton are vulnerableto the ocean's warming trend. Warming changes key characteristics of the ocean and can affect phytoplankton growth, since they need not only sunlight and carbon dioxide to grow, but also nutrients.
Stephanie Dutkiewicz, a scientist in MIT's Center for Global Change Science, built a climate model that projects changes to the oceans throughout the century. In a world that warms up by 3℃, it found that multiple changes to the colour of the oceans would occur. The model projects that currently blue areas with little phytoplankton could become even bluer. But in some waters, such as those of the Arctic, a warming will make conditions riper for phytoplankton, and these areas will turn greener. "Not only are the quantities of phytoplankton in the ocean changing." she said, "but the type of phytoplankton is changing."

The problem of robocalls has gotten so bad that many people now refuse to pick up calls from numbers they don't know. By next year, half of the calls we receive will be scams (欺诈).We are finally waking up to the severity of the problem by supporting and developing a group of tools, apps and approaches intended to prevent scammers from getting through. Unfortunately, it's too little, too late. By the time these "solutions" (解决方案) become widely available, scammers will have moved onto cleverer means. In the near future, it's not just going to be the number you see on your screen that will be in doubt. Soon you will also question whether the voice you're hearing is actually real.
That's because there are a number of powerful voice manipulation (处理) and automation technologies that are about to become widely available for anyone to use .At this year's I/O Conference ,a company showed a new voice technology able to produce such a convincing human-sounding voice that it was able to speak to a receptionist and book a reservation without detection.
These developments are likely to make our current problems with robocalls much worse. The reason that robocalls are a headache has less to do with amount than precision A decade of data breaches (数据侵入) of personal information has led to a situation where scammers can easily learn your mother's name, and far more. Armed with this knowledge, they're able to carry out individually targeted campaigns to cheat people. This means, for example, that a scammer could call you from what looks to be a familiar number and talk to you using a voice that sounds exactly like your bank teller's, ricking you into "confirming" your address, mother's name, and card number. Scammers follow money, so companies will be the worst hit. A lot of business is still done over the phone, and much of it is based on trust and existing relationships. Voice manipulation technologies may weaken that gradually.
We need to deal with the insecure nature of our telecom networks. Phone carriers and consumers need to work together to find ways of determining and communicating what is real. That might mean either developing a uniform way to mark videos and images, showing when and who they were made by, or abandoning phone calls altogether and moving towards data-based communications-using apps like Face Time or WhatsApp, which can be tied to your identity.
Credibility is hard to earn but easy to lose, and the problem is only going to harder from here on out.

Alice Moore is a teenager entrepreneur (创业者), who in May 2015 set up her business AilieCandy. By the time she was 13, her company was worth millions of dollars with the invention of a super-sweet treat that could save kids' teeth, instead of destroying them.
It all began when Moore visited a bank with her dad. On the outing, she was offered a candy bar. However, her dad reminded her that sugary treats were bad for her teeth. But Moore was sick of missing out on candies. So she desired to get round the warning, "Why can't I make a healthy candy that's good for my teeth so that my parents can't say no to it?" With that in mind, Moore asked her dad if she could start her own candy company. He recommended that she do some research and talk to dentists about what a healthier candy would contain.
With her dad's permission, she spent the next two years researching online and conducting trials to get a recipe that was both tasty and tooth-friendly. She also approached dentists to learn more about teeth cleaning. Consequently, she succeeded in making a kind of candy only using natural sweeteners, which can reduce oral bacteria.
Moore then used her savings to get her business of the ground. Afterwards, she and her father secured their first business meeting with a supermarket owner, who finally agreed to sell Moore's product-Cancandy.
As CanCandy's success grows, so does Moore's credibility as a young entrepreneur. Moore is enthusiastic about the candy she created, and she's also positive about what the future might bring. She hopes that every kid can have a clean mouth and a broad smile.
Meanwhile, with her parents' help, Moore is generally able to live a normal teenage life. Although she founded her company early on in life, she wasn't driven primarily by profit. Moore wants to use her unique talent to help others find their smiles. She donates 10% of AilicCandy's profits to Big Smiles. With her talent and determination, it appears that the sky could be the limit for Alice Moore.

| A． |
To earn more money. |
| B． |
To help others find smiles. |
| C． |
To make herself stand out. |

The Cost of Thinking
Despite their many differences, all human beings share several defining characteristics, such as large brains and the ability to walk upright on two legs.
The first unique human characteristic is that humans have extraordinarily large brains compared with other animals. It seems obvious that evolution should select for larger brains. Mammals (哺乳动物) weighing sixty kilograms have an average brain size of 200 cm 2. Modern man has a brain averaging 1200-1400 cm 2. We are so fond of our high intelligence that we assume that when it comes to brain power, more must be better. Unfortunately, that is not the case.
The fact is that a huge brain is a huge drain-consumption of energy-on the body. I's not easy to carry around, especially when boxed inside a massive skull (倾骨). It's even harder to provides energy. In modern man, the brain accounts for about 2-3%of total body weight but it consumes 25% of the body's energy when the body is at rest. By comparison, the brains of apes (类人猿) require only 8%of rest-time energy. Early humans pad for their large brains in two ways. Firstly, they spent more time in search food. Secondly, their muscles grew smaller and weaker. It's hardly an obvious conclusion that this is a good way to survive. A chimpanzee (黑猩猩) can't win an argument with a modern man, but it can tear the man apart like a rag doll.
Another unique human characteristic is that we walk upright. Standing up, it's easier to find food or enemies. In addition, their arms that are unnecessary for moving around are freed for other purposes, like throwing stones or signaling. As a result, humans can perform very complex tasks with their hands.
Yet walking upright has its disadvantage. The bone structure of our ancestors developed for millions of years to support a creature that walked on all fours and has a relatively small head. Adjusting to an upright position was quite a challenge, especially when the bones had to support an extra-large skull. Humankind paid for its broad vision and skillful hands backaches and painful necks.
We assume that a large brain makes huge advantages. It seems obvious that these have made humankind the most powerful animal on earth. But humans enjoyed all of these advantages for a full 2 million years during which they remained weak and marginal creature. Thus humans who lived a million years ago, despite their big brains and sharp stone tools, lived in constant fear of meat-eating animals.
