Recently some American scientists have given a useful piece of advice to people in industrialized nations．They say people should eat more of the same kind of food eaten by humans living more than 10,000 years ago．{#blank#}1{#/blank#}

    The scientists say that the human life has changed greatly．Our bodies have not been able to deal with these changes in lifestyle and this had led to new kinds of sicknesses．{#blank#}2{#/blank#}So they are called "diseases of civilization"．Many cancers and diseases of the blood system are examples of such diseases.

    Scientists noted that people in both the Old Stone Age and the New Stone Age enjoyed very little alcohol or tobacco, probably none．{#blank#}3{#/blank#} However, a change in food is one of the main differences between life in ancient times and that of today.

 Stone Age people hunted wild animals for their meat, which had much less fat than domestic ones．They ate a lot of fresh wild vegetables and fruits．They did not have milk or any other dairy products, and they made very little use of grains．{#blank#}4{#/blank#} We eat six times more salt than our ancestors．We eat more sugar．We eat twice as much fat but only one third as much protein and much less vitamin C.

    {#blank#}5{#/blank#} But scientists say that we would be much healthier if we eat much the same way the ancient people did, cutting the amount of fatty, salty and sweet food.

 A．Modern people used to suffer from "diseases of civilization".

 B．People today probably don't want to live like our ancestors.

 C．These new sicknesses were not known in ancient times.

 D．Ancient people also got lots of physical exercise.

 E．In that case, they would live much healthier.

 F．But today, we enjoy eating a lot of these.

 G．Stone Age people lived a simple life.

    It's easy to spot signs of physical suffering, but much emotional pain can be easily masked.{#blank#}1{#/blank#} “We don't tend to have conversations about mental well-being,” says Dr. Barbara Van Dahlen, a clinic psychologist. Simply asking someone “How are you” may just get “Fine, thank you”, says Van Dahlen. “It's important to be aware of what could lead to somebody needing help they're afraid to ask for,” she adds. The following are four signs a friend might need help.

    {#blank#}2{#/blank#} If you sense something different about the way your friend is acting — maybe he's not smiling much these days, for instance — trust your feelings and reach out. “Try saying, ‘I see these things. I care about you. Can I be of help?'”, Van Dahlen says.

    He's unusually unhappy or annoyed.

    {#blank#}3{#/blank#} “It may take more than one time to follow up if you're talking to someone who is upset,” Van Dahlen says, “but if a friend responds with anger, that could mean you're onto something.”

    He's less put together than usual.

    Drinking more and ignoring personal hygiene (卫生) can be signs that someone is in trouble. Don't consider these behaviors are nothing.{#blank#}4{#/blank#} He seems overwhelmed (压倒) by life.

    No one is happy all the time, but if your once optimistic friend can't find anything to be hopeful about, he may be having thoughts of worthlessness, sadness and something negative. “{#blank#}5{#/blank#}” says Van Dahlen, “so that more people can get the help they need.”

A. He's acting a bit more withdrawn.

B. He doesn't seem like himself lately.

C. Instead treat them as a sign to care for your friend.

D. Getting angry quickly and easily can be a sign that something is wrong.

E. It's a constant effort to bring into the open discussions about mental health.

F. Many people avoid talking about it no matter how close they are to someone.

G. We want people to get comfortable being more open and discussing mental health.

    Difficult financial times don't mean your giving shuts down.{#blank#}1{#/blank#} There are so many ways to give back that won't hurt your wallet and will enrich your life.

⒈Pick up the phone

    Calling someone “for no reason” is an important opportunity to show them that you are thinking of them. You are taking time out of your busy day to reach out. Everyone needs someone to just listen sometimes. They may be filled with joy or sadness{#blank#}2{#/blank#}

⒉Write a note

    {#blank#}3{#/blank#} It is one thing to say it, but it can be even more meaningful to put it in writing. What if you made a commitment to write a thank-you note to someone every week?

⒊ {#blank#}4{#/blank#}

    You never know what someone might be going through a painful divorce, a tough college semester, or just a bad day. Opening up your home will make someone feel appreciated. In addition, it costs less than going out. The leftovers from this dinner can be packaged up for homeless people. That's double giving!

⒋Set aside money from a daily routine to donate

    Giving doesn't have to mean a life full of sacrifices. You can still buy a burger or get your nails done{#blank#}5{#/blank#}Donate the money you saves: Even $ 5 can make a difference in someone's life.

A. Give a gift to the stomach.

B. Invite someone over for dinner.

C. To take your awareness to a new level, move beyond money.

D. But instead of buying much coffee every week, you can drink less.

E. While some people enjoy receiving gifts, all of us appreciate a kind word.

F. Instead, they allow you to examine how your time and money are spent.

G. Be there to celebrate their good news, or support them with sympathy.

    Tests can be stressful even for the best students. {#blank#}1{#/blank#} Fortunately, there are several steps you can take to make your stress much more manageable.

    Get Enough Sleep

    Getting 6 hours of sleep or less can put you into what's called a sleep deficit(不足),which makes you less sharp mentally and prevents you from performing properly on tests. {#blank#}2{#/blank#} This way, you needn't stay up for the test and can get a good night of sleep before your big day.

    Study Smarter

    {#blank#}3{#/blank#} Make a list of the most important things you need to learn and hit the items at the top of the list first. This will ensure they're mostly covered if you run out of time. Make a list of all the work you have to do, estimate how long each item will take, and compare that with the amount of hours you have available. This will tell you if you can carefully read or just skim, how many times you can afford to revise the papers.

    Visualize(想象)Success

    A proven way to build your confidence is to visualize yourself taking the tests and doing wonderfully. Visualization can not only help you perform better in the tests but can help you remember facts. You can create detailed situations that involve the information you're trying to remember.  {#blank#}4{#/blank#} 

Stay Calm

    There're several techniques that can help you calm down quickly.{#blank#}5{#/blank#} Just close your eyes, take a deep breath, hold it for a while and then let it out slowly. Your stress will come out with your exhales(呼气)

A. Be organized with your studies.

B. Extra time on tests can bring success to students.

C. Test anxiety has a negative impact on your performance.

D. In this process you can strengthen the facts in your memory.

E. Breathing exercises can be extremely effective in helping you relax.

F. So it's very important to get all your studying done before your exam.

G. There are options for easing stress and potentially improving test performance.

Jessica: What are you doing now?

Susan: I {#blank#}1{#/blank#} (listen) to the news.

Jessica: Is there anything urgent? If not, I {#blank#}2{#/blank#} (real) want to have a talk with you.

Susan: No, there isn't. What's wrong?

Jessica: I think your grandma is {#blank#}3{#/blank#} nice person, but I can't help {#blank#}4{#/blank#} (think) that she doesn't like me.

Susan: Oh, she likes you. She is just old-fashioned and has her own way of doing things.

Jessica: But every time I clean the kitchen, she comes in {#blank#}5{#/blank#} me and cleans it again. Then she complains that the house is not tidy. I can't deal with this.

Susan: Just let her do it and ignore (忽视) her. She thinks if you don't get on your hands and knees {#blank#}6{#/blank#} (clean) the floor, the floor won't be clean.

Jessica: What a silly thing to say! What's a mop (拖把) for? And what's wrong with my cooking?

Susan: Nothing. I love your cooking.

Jessica: Then why does she complain about it? This morning she suggested that I {#blank#}7{#/blank#} (go) to cooking school to learn {#blank#}8{#/blank#} to cook.

Susan: Jessica, just ignore her. She only wants to make sure {#blank#}9{#/blank#} we can take care of ourselves.

Jessica: Don't we?

Susan: Yes, we do. I'm sorry that she makes you suffer {#blank#}10{#/blank#} stress, but I wish you'd learn to get along with her. Remember, she's an elder.

Jessica: Don't worry. When things get tense (紧张的), I just remind myself that she's your grandma, and I keep my temper (脾气) under control and my mouth shut.

    Are Your Clothes Causing Pollution? Very small pieces of plastic, called microfibers, are polluting rivers and oceans. {#blank#}1{#/blank#} Clothes worn for outdoor activities and exercise are often made of artificial material, which is useful in keeping warm. But they contain very small plastic fibers, which may also be harming the environment when you wash them. When people wash these clothes, very small pieces go down the drain （下水道） with the wash water.

    {#blank#}2{#/blank#}

    Pollution caused by plastic is not new，but recent studies have shown the effect of microfibers in the environment.

    Studies show very small microfibers are ending up in our waters，which may come from waste water treatment factories. A 2015 study found them in fish from California.

    Microfibers, effect on food supplies.

Beyond the waterways，the researchers say microfibers may end up in soil and agricultural lands. {#blank#}3{#/blank#}This means there is much to be learned about microfibers and the environment. Some studies have shown that microfibers end up inside sea animals，like oysters. {#blank#}4{#/blank#} Researchers say that the fibers tend not to move into the tissue of the fish，but it needs more study.

    Steps to save or keep microfibers from the environment.

    Until more information becomes known，there are steps to take to reduce the amount of microfibers in the environment. People should use less of the artificial materials. If we already have those in our lives and we're using them，an important step would be washing them less. {#blank#}5{#/blank#} A bag is being designed in which to wash these clothes. It traps the microfibers in the bag and it may be available for purchase soon.

A. New technology may also help.

B. Studies on microfibers in the environment.

C. They can also move around the atmosphere.

D. Studies on how much of the microfibers is released.

E. The source of these microfibers may surprise you: your clothes.

F. Washing machines keep microfibers from escaping with wash water.

G. So if these microfibers have been found in fish and seafood, are they safe to eat?
