Do you like eating processed meat? If you do, think twice now if you want to eat such meat for the sake of your health. Why? It's because eating processed meat can cause cancer, World Health Organization (WHO) experts said last Monday.

    Processed meat is the meat that has been preserved by salting, smoking, drying or canning. Experts from the WHO's International Agency for Research on Cancer (IARC) in Lyon, France studied 800 patients. The experts connected processed meat, such as hot dogs and bacon, with at least three kinds of cancer. A person who eats 50 grams of processed meat per day—about two pieces of bacon—increases his or her risk of bowel(肠) cancer by 18 percent.

    The IARC has included processed meat in its Group 1 list, for which there is “enough evidence” of connection with cancer. Tobacco is also on the Group 1 list.

WHO experts also say red meat, including beef, lamb and pork, is “probably” carcinogenic (致癌的) to humans. Dr. Kurt Strait is with the IARC. He said in a statement that the risk of cancer increases with the amount of meat a person eats. Health experts in some countries advised against eating large amounts of red and processed meat. But those suggestions had been centered on the increased risk of heart disease and obesity.

    However, meat industry groups protest the result of the WHO study. They say that meat is part of a balanced diet. They also say the causes of cancer are broad, and include environment and lifestyle factors.

    The WHO report cites the Global Burden of Disease project, which shows that diets high in processed meat lead to 34,000 cancer deaths per year worldwide.

—Hello, Xiao Li, come in.

—Hello! {#blank#}1{#/blank#}

—I'm just writing a letter to Wang Ling in London.

—Oh. {#blank#}2{#/blank#}

—I haven't seen you for a long time.

—No, I've been very busy because I'm doing a course in Business English. I had my first exam yesterday.

— {#blank#}3{#/blank#}

—I think I've done all right. Listen, I've got some good news.

— {#blank#}4{#/blank#}

—My company has just told me that they're sending me to England for a year.

— {#blank#}5{#/blank#} And Wang Ling will be able to show you around London.

A. Oh, what's that?

B. How are you?

C. Give him my best wishes.

D. Who told you?

E. Are you busy?

F. How did it go?

G. That's wonderful.

The cane toad (海蟾蜍) was imported to Australia in 1935 to protect sugarcane crops. {#blank#}1{#/blank#} Experts estimate that there are currently over 200 million samples spread across Northern Australia, and the numbers are only growing. The increasing population is proving to be deadly for many native Australian animal species that hunt the toads as food. {#blank#}2{#/blank#}

    While some animals have learned to completely avoid the frogs, the Australian monitor lizards continue to be killed by them. The lizards that catch small animals love eating cane toads. {#blank#}3{#/blank#} It takes the cane toad less than 30 seconds to release enough poison to kill a lizard.

{#blank#}4{#/blank#} They decided to train the lizards to avoid the cane toads. To carry out the idea they went to a region of northwestern Australia that had not yet been invaded by cane toads and fed the wild lizards with young cane toads. Though the smaller animals release the same poison as the adults, they do so in smaller amounts. {#blank#}5{#/blank#} The researchers say it took just one or two tests to teach the lizards to stay away from cane toads. They continued to avoid the animals even when the larger cane toads arrived.

A. Not surprisingly, their population has dropped sharply.

B. Unfortunately, in most cases, it turns out to be their last meal.

C. With very few natural enemies, their population began to grow rapidly.

D. Now a team of researchers came up with a good plan to save the lizards.

E. Gradually, the lizards learned to eat only the mildly poisonous cane toads.

F. Therefore, while the poison does make the lizards sick, it does not kill them.

G. That's because cane toads release some deadly poison when they sense danger.

    Schools consume a large amount of energy, which has a bad effect on the environment.{#blank#}1{#/blank#}, there are lots of ways that you can help your school save energy. Look for simple changes your school can make and band together with others to make an even bigger effect.

    {#blank#}2{#/blank#}Even something as simple as turning off the lights when you leave a room can help to save energy. Turn off the lights in classrooms that are not being used and in other areas, such as empty bathrooms and unoccupied multi-purpose rooms.

    Use natural light when the sun is bright. It may not always be necessary for you to have the lights on in your classroom. There may be times of day when the sun is especially bright and enough for what you are doing in your classroom. {#blank#}3{#/blank#}.

    Set up a recycling station at your school Recycling is a great way to save energy because it reduces the need to produce new materials.{#blank#}4{#/blank#}, then ask your school principal if you can set one up.

    Get others involved.{#blank#}5{#/blank#}. Either as an individual or as a team, you can create and put up signs around your school. Try using signs that remind people of things they can do to save energy and also some signs that raise awareness of saving energy.

A.Postsigns about conserving energy

B.Whether you are a teacher or a student

C.Ifyour school does not have one

D.Turn off your computer when it's not used

E.Shut down the lights when rooms are not in use

F.Other times of day you might only need half of the lights

G. If your school's garbage company offers recycling services

    Life can be a lonely thing without friends. Acquaintances (熟人) are easy to come by but true friends are a whole other story. {#blank#}1{#/blank#} Learn these four steps if you'd like to be a true friend that can be relied on.

    ●Be present for their highs and lows.

    If you're absent during my struggle, don't expect to be present during my success.

    （Will Smith）

    It's easy to be there for our friends when they ask us out for fun things. {#blank#}2{#/blank#} You might not feel comfortable while spending time with an emotionally weak person on the verge of tears, but true friends are always there when they're needed the most.

    ●{#blank#}3{#/blank#}

    When people talk, listen completely. Most people never listen.

    （Ernest Hemingway）

    Give your friends the gift of silence so they can drop their baggage and get on with living.

    ●Accept them as they are.

    Happiness can exist only in acceptance.

    （George Orwell）

    If you can't accept people as they are, you will never know the feeling of true friendship. {#blank#}4{#/blank#}

    ●Forgive the past.

    Holding onto anger is like drinking poison and expecting the other person to die.

    （Buddha）

    {#blank#}5{#/blank#} If so, you should understand that even the best of us suffer from the occasional slip of the tongue. Holding onto anger over a small mistake will make you look petty (小气的), so let it go.

    Do you know the proverb "no pains, no gains"? It gives the impression that we ought to be suffering while we study. It seems that the only way to know if we're putting in enough work is how much hardship we bear. We are totally taken up with study, shutting ourselves away for a big exam. Is that necessarily true?

    When we haven't taken the time to come up with another idea, we just shut ourselves in a room with a book. It's no surprise that we find revision boring and difficult. Just as children learn from playing, we can learn from doing, or at least from study techniques that interest us, rather than make us switch off. Shutting ourselves away can make us learn to hate studying, leading to a situation where, instead of being able to concentrate on our work, we are troubled by how unfair it is that we must study. This can be part of a vicious(恶性的)cycle that traps us into ineffective revision, or poor progress fueling further annoyance.

    Thankfully, working in the company of other people really helps fight against that. We just need to learn how to deal with distractions(分心). It's not necessary to avoid all company, just lazy company. They constantly try to keep others in conversation. While studying in the same room with someone who is ironing or working out is perfectly possible. Of course, it's also a good idea to avoid the company of people involved in activities where you would rather be playing than studying. Working while sitting next to someone playing video games is most likely to end with a new high score games rather than productive revision.

    If being around others means working in a noisy environment, a pair of headphones and some background music can block out noises. They also act as a psychological barrier, so that people think twice before interrupting you. Besides, we should know friends and family can lessen feelings of isolation. And connecting with other people makes us happy, so it's important not to give that up and to make sure that we take the time to socialize.
