A memorable science project

    If someone tells you to remember a phone number or address, it feels like an easy task at first. You repeat the numbers to yourself, either aloud or in your mind. But after just a few seconds you might find yourself starting to doubt your own memory.{#blank#}1{#/blank#}Thus, it will try to throw away information that seems old or irrelevant. There are ways of helping our minds retain (记住) information, however, and in this activity you will explore ways that we lose and keep memories.

    Short-term, or working memory, is a way of describing most people's abilities to store a small amount of information for a brief period of time in a readily accessible form{#blank#}2{#/blank#} People don't have to stop and think to remember something in short term memory.

    {#blank#}3{#/blank#}Such techniques include visualizing (观察) the information in a surprising way or linking pieces of information together so that one reminds you of the other. In the case of visualizing information, this could be as simple as remembering you parked your car on the fifth floor in the D section by picturing five dogs sitting in your car!{#blank#}4{#/blank#} If you need to purchase cereal (谷物), milk, fruit, cheese and eggs, you could imagine the cereal in a bowl, with milk pouring over it and pieces of fruit on top. Then imagine cracking an egg over everything, and it's full of melted cheese! These may seem simple or even silly.{#blank#}5{#/blank#} In this activity you'll test the recall of a few friends or family members, and learn a few tricks for improving memory!

A. There are many techniques for improving memory.

B. Our brain is always seeking new and useful information.

C. Short-term memory has a short duration but is quickly and easily accessed.

D. In addition, linking information could help you remember your grocery list.

E. Retaining that information over longer periods of time becomes difficult yet.

F. Your short-term memory has a limited amount of space to store information.

G. However, they are proved to be good ways for improving memory by scientist.

    Lemon water is pretty popular. It's offered as a free upgrade to regular water at pretty many restaurants.{#blank#}1{#/blank#}, others are devotees of the possible health benefits. Here's what may happen if you take up the lemon water habit.

    Easier weight loss

    Studies in mice indicate that the antioxidants(抗氧化剂) in lemons can reduce weight gain despite a high-fat diet. More studies are needed to determine if the results can be applied to humans, but anecdotal evidence is favorable. People who drink lemon water regularly report easier weight loss, though it is unclear if the combination of lemon and water is the fundamental driver.{#blank#}2{#/blank#}.

    Get enough vitamin C

    Vitamin C is an important antioxidant that has a ton of health benefits. It can only be gotten from food as our bodies don't produce it alone. Getting your RDA (Recommended Daily Allowance) of vitamin C can lower the risk of heart disease, stroke, and high blood pressure. Vitamin C is good for your skin and bonds with free radicals (自由电子) that accelerate aging.{#blank#}3{#/blank#}, but they're a great source nevertheless.

    Stabilized moods

    Studies have found that smelling lemon scent reduces stress hormones that regulate mood. Drinking lemon water offers this benefit as well as the vitamins and potassium(钾) in the fruit. {#blank#}4{#/blank#}, and high blood pressure is related to stress, so not getting enough potassium can certainly affect your mood. All in all, lemon water can be a calming drink.

    In the end, drinking water is never a bad call, and there is absolutely no reason not to add lemon to it. Drinking lemon water provides some helpful nutrients and antioxidants. Give it a try!{#blank#}5{#/blank#}.

A. Lemon is a common smell in all manner of cleaning products

B. Potassium plays a huge part in regulating blood pressure

C. There is nothing to lose

D. Lemons aren't the highest in vitamin C

E. While some people drink it simply because of its taste

F. If adding lemon to water can encourage people to drink more

G. It could be that drinking more water helps dieters to feel full and avoid overeating

    Whether you use a GPS device (设备) in your car or Google Maps on your smartphone, few of us travel anymore without digital help. {#blank#}1{#/blank#} For one thing, GPS isn't as accurate as you might think. What's more, science is beginning to discover that people who rely only on navigational technologies may have a poor sense of place during travel.

    {#blank#}2{#/blank#} They soon become outdated as cities change, requiring users to continually purchase updated versions. They're also easily damaged from exposure to water, poor weather conditions and other physical forces.

    However, paper maps still offer a few advantages that technologies can't. For example, studying a map allows you to get a full view of where you're going, including the roads, forests, towns, historic sites, rivers and mountains you'll come across along the way. Many older maps are wonderful, offering a lovely feast for the eyes. {#blank#}3{#/blank#}

    Research by Toru Ishikawa and colleagues at the University of Tokyo found that GPS users spent 30％ more time looking at their device than those who used a paper map. {#blank#}4{#/blank#} Instead they tended to stare at their screens and follow directions, never gaining a full view of where they were going.

    Therefore, go ahead and use your GPS, but also carry a paper map as a handy backup. {#blank#}5{#/blank#} Also it could even be a life-saver!

Dear Boris,

{#blank#}1{#/blank#}After I had spent a week with my English family, I slowly began to understand their English a little better. {#blank#}2{#/blank#}Students in my group are from different cities of Britain and their dialects are different too! Some of their accents are quite strong and they also have their own words and expressions. {#blank#}3{#/blank#}Before I came to England I had thought that fish and chips were eaten every day. That's quite wrong! I get rather annoyed now when I hear all the foolish words about typical English food. I had expected to see "London fog". Do you remember our texts about it? We had no idea that most of this "thick fog" disappeared many years ago when people stopped using coal in their homes. But the idea to speak about weather was very helpful. {#blank#}4{#/blank#}On the other hand, habits are different. People tell me what is typical British here in London is not always typical in Wales or Scotland. {#blank#}5{#/blank#}But what is ordinary for all British is that they follow traditions(传统). Probably Britain has more living signs of its past than many other countries. And people have always been proud of having ancient (古老的) buildings in capitals, big cities and the countryside. I will tell you more about Britain in my other letters. Love from Britain.

A. The weather in London is really changeable.

B. I have difficulty in understanding my classmates.

C. Thanks for your nice letter.

D. The family I live with are friendly.

E. It's very different from what I learned at school.

F. Local habits and traditions are not the same as what we knew.

G. But it's not the language that's different and surprising.
