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.

    How to test best

    It's back to school, which means it's back to tests, which might also means it's back to being majorly stressed out.{#blank#}1{#/blank#} Here are some simple ways to prepare thoroughly for tests.

    Schedule study time.

Trying to do all studying the night before a test makes it impossible to master all the materials.{#blank#}2{#/blank#} Instead, prepare for a test by scheduling study time each day for several days before.

    Use your time wisely.

    {#blank#}3{#/blank#} Also, make sure you have all the supplies（用具）you need to study so you don't lose focus. While studying, be sure to make regular short breaks. Get a snack, take a bathroom break or play a quick computer game when it feels as if your brain is about to explode.

    {#blank#}4{#/blank#}

    Studying with a parent or friends can help you understand the material better and to learn from one another. Have every person or pair take a part of the material, and come up with questions to quiz the group. Keep the group small. Have everyone take turns as the group leader, who will assign the material, and make sure that conversation stays on what is being studied.

    Don't forget last-minute preparation.

Have your sharpened pencils and other things in your bag ready the night before the test. It's important to get a good night's sleep and then eating a healthy breakfast the next morning.{#blank#}5{#/blank#}Also, studying all the way up until test time can only create more anxiety. Stop studying an hour beforehand.

B. Stay cool before the test.

C. It doesn't have to be this way.

D. This will help you store important information.

E. This way, both your mind and body are fully prepared.

    Traditional Chinese medicine (TCM) isn't supported by most Westerners. {#blank#}1{#/blank#}

    TCM will be included in the new version of the International Classification of Diseases (ICD), which will be published by the World Health Organization in 2019, Nature magazine reported. {#blank#}2{#/blank#} Ryan Abbott at the Center for East-West Medicine at the University of California, Los Angeles, US, said this could benefit TCM.

    {#blank#}3{#/blank#} For example, during the 2016 Rio Olympic Games, US swimmer Michael Phelps was seen with circular bruises(瘀青) on his body. Such bruises are caused by cupping, a traditional Chinese medicinal practice that has been around for more than 2,000 years.

    In 2015, Chinese scientist Tu Youyou was awarded the Nobel Prize in Medicine for her discovery of artemisinin(青蒿素), a drug that can cure malaria(疟疾). She said she was inspired by traditional Chinese medicine.

    {#blank#}4{#/blank#} Twenty-six TCM centers were set up overseas over three years, according to a 2017 report published by Xinhua News Agency.

    TCM still faces many challenges, such as a lack of clinical evidence as to precisely how it works. {#blank#}5{#/blank#} Some say that TCM methodology should be combined with modern scientific methods to make it more acceptable to people outside of China.

A. However, this is starting to change.

B.TCM has cured millions of people in the world.

C. China has made some efforts to promote TCM overseas.

D.TCM's effectiveness has been difficult to study or provide evidence for.

    If one thing on your wish-list is a stress-free holiday, then here are some shopping tips prepared for you, which will save both your time and money.

    Don't be tough on your brains. {#blank#}1{#/blank#} Don't be afraid to look for clues and ask for ideas. First, see whether the folks on your to-buy-for list have already dropped some valuable hints of their dreamed items.

    {#blank#}3{#/blank#} You really can enlist your own personal helpers. Don't feel guilty about that—after all, Santa employs helpers too.

We're not talking just high-end stores such as Blooming-dale's and Nordstrom. {#blank#}4{#/blank#} They're all hungry to win your business away from online retailers. But you'll likely need an appointment, so call ahead or search stores' websites for “personal shopping”. You'll typically find a link on the home page under Contact Us or Services.

    Have gifts delivered. Time is money, and for not a lot of money you can save a lot of time by having your gifts delivered right to your door. Some mom-and-pop shops offer delivery service while chain stores tend to charge for that, but it still might be worth paying for the convenience. {#blank#}5{#/blank#} First go to postmates.com or download the free app and see whether it's available in your area. Then type the name of a store into the search bar, click on the store, and enter the item you want.

B. Can't figure out what to buy?
