    Most drinks stating that they are fruit-flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.

    “Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be non-existent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. {#blank#}1{#/blank#} It will increase profits, and consumers won't always realize they are being tricked.”

    Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry-flavored products sold in stores. {#blank#}2{#/blank#} Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.

    {#blank#}3{#/blank#} Let's take jam as an example. Some strawberry-flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.

    {#blank#}4{#/blank#} Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. {#blank#}5{#/blank#} Unfortunatly, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”

    Ebola is a dangerous virus that can cause people to get very sick and even die. The virus is causing the biggest problems in western Africa, where it has spread quickly. {#blank#}1{#/blank#} But it can get worse and cause life-threatening symptoms(症状), such as bleeding and trouble breathing.

    {#blank#}2{#/blank#}

    {#blank#}3{#/blank#}

    Where did Ebola come from?

The Science of Risk-Seeking

    Sometimes we decide that a little unnecessary danger is worth it because when we weigh the risk and the reward, the risk seems worth taking. {#blank#}1{#/blank#} Some of us enjoy activities that would surprise and scare the rest of us. Why? Experts say it may have to do with how our brains work?

    The reason why any of us take any risks al all might have to do with early humans. Risk-takers were better at hunting, fighting, or exploring. {#blank#}2{#/blank#} As the quality of risk-taking was passed from one generation to the next, humans ended up with a sense of adventure and a tolerance for risk.

    So why aren't we all jumping out of airplanes then? Well, even 200,000 years ago, too much risk-taking could get one killed. A few daring survived, though, along with a few stay-in-the-cave types. As a result, humans developed a range of character types that still exists today. So maybe you love car racing, or maybe you hate it. {#blank#}3{#/blank#}

    No matter where you are on the risk-seeking range, scientists say that your willingness to take risks increases during your teenage years. {#blank#}4{#/blank#} To help you do that, your brain increases your hunger for new experiences. New experiences often mean taking some risks, so your brain raises your tolerance for risk as well.

    {#blank#}5{#/blank#} For the risk-seekers a part of the brain related to pleasure becomes active, while for the rest of us, a part of the brain related to fear becomes active.

    As experts continue to study the science of risk-seeking, we'll continue to hit the mountains, the waves or the shallow end of the pool.

A. It all depends on your character.

B. Those are the risks you should jump to take.

C. Being better at those things meant a greater chance of survival.

D. Thus, these well-equipped people survived because they were the fittest.

E. This is when you start to move away from your family and into the bigger world.

F. However, we are not all using the same reference standard to weigh risks and rewards.

    Are you planning to go to university? {#blank#}1{#/blank#}Perhaps you will be choosing the classes you want to take, finding accommodation and enrolling in other activities. However, if you go to university in Chile there is something extra you must do before you can begin.

    An essential part of starting university in Chile is the “mechoneo”{#blank#}2{#/blank#} Students beginning their first year at university are “welcomed” by the older university students. They are taken from their classrooms on an unknown day and blindfolded. The older students tear their clothes, cut their hair, and cover them in raw eggs and other disgusting things.

    {#blank#}3{#/blank#} This will be based on how well the students do the activities, and many students try very hard as they want to be the king or queen of the year. The older students then take away everything of the younger students and tell them they must go out onto the street and ask people for money. They will need to bring back a certain amount of money in order to be given their things back.{#blank#}4{#/blank#}

    During March it is common to see new university students all around town wearing ripped, dirty clothes and covered in paint and mess. But the “mechoneo” is increasingly a source of dispute and debate. Some students see it as an important tradition and a unique experience that help new arrivals get to know everyone.{#blank#}5{#/blank#} There have been campaigns to ban or soften it in favour of more “positive welcomes'', and student organizations in some universities have voted to end the “mechoneo” completely.

G. The money is then used to have a massive welcome party at night-time.

Pronunciation Tips

    These English pronunciation tips will help you get the most out of your Pronunciation Power program.

    {#blank#}1{#/blank#}

    For example, "threw" and "through", although spelled differently, are pronounced the same. Also, identical（相同的） letters or letter clusters（字母组合） in words do not always produce the same sound. For example, the "ough" in "though" and "through" represents a different sound in each word. {#blank#}2{#/blank#}

    Imagine a sound in your mind before you say it.

    Try to visualize（想象)）the positioning of your mouth and face. {#blank#}3{#/blank#}

    Listen to and try to imitate the Pronunciation Power instructor.

In addition to listening for specific sounds, pay attention to pauses, the intonation（语调） of the instructor's voice and patterns of emphasis. {#blank#}4{#/blank#}

    The English language has many different dialects, and words can be pronounced differently.

    It is important, however, that you pronounce words clearly to ensure effective communication.

    Finally, the Pronunciation Power program is a tool to help you.

    But you must practice what you are learning! Remember that you are teaching your mouth a new way to move. You are building muscles that you do not use in your own language. {#blank#}5{#/blank#} Use the program to exercise your mouth a little bit each day.

A. Read these words over and over again and try to learn them by heart.

B. This can be just as important as the pronunciation of sounds.

C. Learn to practice what you hear, not what you see.

D. So you should force yourself to do what you really don't like to do.

E. Do not confuse pronunciation of words with their spelling!

F. It is like going to the gym and exercising your body.

G. Think about how you are going to make the sound.

What if a tornado passes by and you are struck by flying objects, leaving you with several broken bones? Or maybe next year you crash your car and are badly in need of a life-saving surgery. {#blank#}1{#/blank#}

    All of these incidents, terrible as they are, require money to fix. {#blank#}2{#/blank#} With an insurance policy, you are given a safety net which you can land on in the event that anything terrible happens to you or your family.

    {#blank#}3{#/blank#} As a part of this plan, you will have to pay a premium (保费). It is a monthly or yearly payment to an insurance company. If you do have an insurance plan, then in exchange for your premium money, an insurance company will agree to cover the cost of whatever accident may occur to you. {#blank#}4{#/blank#} For example, if you tend to get sick a lot, you will have to pay more in your premium because it is more likely that you will go to the hospital.

    In many ways, getting an insurance plan is a bit of a bet. {#blank#}5{#/blank#} However, by getting an insurance plan, you can ensure that you will always have a safety net to land on if anything terrible does occur, as you have a guarantee that at least some portion of the cost will be covered by your insurance company.
