    There's nothing better than a walk in the countryside for lifting our spirits.Connecting with nature has been proven to help our mental health.For some,the best tonic is to wander through a forest,but as we admire the trees that surround us,it's worth knowing these trees are doing more than just being nice things to look at.
    We're already aware of the healing properties of trees - they produce oxygen and clean the air we breathe by absorbing about a quarter of all human-caused carbon dioxide emissions.Deforestation isn't helping with this which is why so many people want to save them.But there's more to these impressive forms of vegetation than we might think.Researchers have discovered evidence that proves they are actually intelligent.
    It's thought that trees talk and share resources right under our feet,using a network of fungi (真菌).Under the ground are tree roots,and fixed among them,along with bacteria,are thousands of superfine threads of fungi.And research has shown that they are all interconnected.They can help each other by sharing nutrients,and they can even warn of approaching threats.Scientists say it's like the trees are talking to one another.
    Ecologist Suzanne Simard has called this network the Wood Wide Web.She discovered that parent trees use this network to help their offspring (后代).Speaking to the BBC,she said: "We found that the parent trees would favour those seedlings that were of their own family VS the strangers" by sending them more nutrients.She also found that trees are smart enough to change their behaviour and have managed to adapt and survive in a changing environment.
    So it seems trees really are the stars of our natural world,and with around three trillion of them on our planet,it's time to show them some respect if we want them to flourish.

  • 1."An apple a day keeps the doctor away." Similarly,if we drink a little more water every day,we may find that we need to go to the doctor less often.A healthy diet is made up of water and different kinds of foods.We know that healthy foods like fruits,vegetables and fish ,are important as they offer energy and fiber,without giving us much fat and sugar.But why is water important?
       The human body needs water to survive.Water is important as it carries poisons and waste out of our bodies.However,doctors advise us to drink plenty of water ,much more than the small amount we need to stay alive.
       Some doctors believe that water is important for health in all kinds of ways.They believe that many illnesses and health problems appear as a result of dehydration--a lack of water.Most people are dehydrated (脫水)at least some of time,although they probably don't know it.It is surprising to learn that if we feel thirsty,we are already in the first stages of dehydration.In fact,we are advised to drink water before we feel thirsty.
       These doctors think that health problems such as headaches,high blood pressure could be helped if people drink more water.They also believe that drinking more water can help people who are fat.Water contains no calories so it will not make us gain weight.If we drink water ,we will probably drink less sugary soft drinks.Doctors also believe that drinking more water may stop people from overeating.They say that many people think that they are hungry when they are,in fact,thirsty.Doctors suggest,therefore,that we eat less food and drink more water.
       There are still many health problems that cannot be solved by drinking water,so we should not stop going to see the doctor completely.

    (1)From the text,we know water can carry
    .
    A.energy and fibre in our bodies
    B.fruit,vegetables and fish in our bodies
    C.sugar and fat out of our bodies
    D.poisons and waste out of our bodies
    (2)Lack of water caused many people to put on weight because
    .
    A.It makes them hungry
    B.they think they are hungry and eat too much
    C.Water has no calories
    D.they think they are thirsty and eat less
    (3)Doctors suggest that we should
    .
    A.eat less food and drink less water
    B.not eat food and just drink water
    C.eat less food and drink more water
    D.eat more food and drink more water
    (4)Which of the following is NOT mentioned in the text?

    A.People should drink water and not eat fruit.
    B.Some health problems start because of a lack of water.
    C.Fruit provides us with energy and fiber .
    D.Drinking more water may stop people from overeating.

  • 2.How to Raise a Child Who Loves Reading Give your kids good books to read.
       By "good" I mean quality literature that makes kids think,not just entertains them.Some books can be fun.(1)
    Keep away from lightweight (內(nèi)容平庸的) books,because they may teach them to turn away from anything that makes their brains work too hard.A diet of lightweight books does not promote the patterns of thought that produce intellectual and personal excellence.
       (2)
    Kids love listening to their parents read,even as they get older,so don't stop reading aloud to your children just because they can read on their own.This is a perfect opportunity to challenge their abilities,vocabulary and worldviews by reading books.
       Remove distractions (使人分心的事物).
       With hand-held devices (3)
    Parents should have these devices powered down and phones put away,and ask them to pull out their books.Once kids finally get into their books,it creates the same quiet,peaceful atmosphere home.
       Talk about books with your kids.
       (4)
    Ask every family member,even the youngest,what they have read that day and what they've learned from it.This will arouse discussion and debate about the issues raised in the books.
       Give our kids paper books,not e-books.
       Studies have shown children keep information better when they read it on paper,as opposed to a screen,so avoid giving your child e-books to read.A paper book allows them to create a relationship with the book,to reread and to become familiar with a book's feel and smell.(5)


    A.Read aloud to your kids.
    B.Take chances to challenge your kids.
    C.That's where parental responsibility comes in.
    D.All these are very real parts of the reading experience.
    E.Parents should inform their kids of the harmfulness of hand-held devices.
    F.The dinner table is a great place to start reflective conversations about books.
    G.But it's important to teach kids to appreciate books that may take effort to consume.
