The Internet, mobile phones and Ipads are part of our lives now. Technology is greatly affecting all ways of our lives, from the ways we work to the ways we play. And it even causes a number of social problems such as cloning humans.

      We have had lots of technology and it has changed our lives a lot. There is no doubt that humans will continue to use more and more technology. Here are some examples of modern technology that will change our ideas and will affect our lives greatly.

     Global positioning system (GPS) (全球定位系统)

      It's a system that uses radio signals from satellites to show exact information. It tells you where the user is on the earth in all weather conditions. It's made up of three parts: satellites, control equipments(设备) on land and receivers.

     Space Technology

      Russian and American scientists have worked together for the international Space Station (ISS) for a long time. They hope the ISS will provide a long-lasting lab. Such a lab will bring humans limitless (无限的) advantages. It's even hoped that one day space technology will take humans to their new houses in space.

     Underwater Robot

     Hercules is a kind of underwater robot with some high technology equipments. It will be used to look for ancient ships which were destroyed into the deep sea during their journey long ago.

     The world is changing so quickly that it's hard for us to catch up with all the new inventions because they seem to come out every month. It's important for us to learn about new technology and the role that it plays in our lives. So we should be willing to accept modern technology, or we will fall behind the times.

    The koala is unique (独特的) to Australia and is an important symbol of the country. The koala is found in open eucalypt (桉树) forests in south-east Queensland. Even if it is called koala bear, this animal has nothing to do with the actual bear. Koalas have thick fur and large cars.

    Their broad, flat nose makes them look cute, similar to teddy bears. In fact koalas aren't cute. They have sharp teeth and very sharp claws (爪)! Koalas are marsupials (有袋类). This means the mother carries her baby in a pocket while it develops, similar to a kangaroo. The baby koala lives in its mother's pocket for the first six months of its life.

    The name “koala” comes from a native Australian word that means “no drink”. The koalas get almost all their water from the eucalyptus leaves they eat. That's where they get their food too.

    Koalas eat only eucalyptus leaves. The eucalyptus trees are where the koalas live, it's also where they sleep. Koalas sleep about nineteen hours a day!

    Why do they sleep so much? Some people think it's because they're lazy. But koalas aren't lazy. They sleep so much because there isn't much nutrition (营养) in eucalyptus leaves. Koalas store hardly any fat, so they must save their energy. One way to do this is to move slowly and sleep a lot. After a day of sleeping they like to move around and eat just after sunset. They live alone most of the time. Koalas are very protective of their trees. If a koala sees another koala eating in its favorite tree, it might tell the other koala to leave by “barking” at it. Koalas do “talk” to each other.

    Besides barks, the males make a deep grunting (呼噜的) sound.

    The mothers and babies talk in soft clicking sounds. If they get scared they may scream like a baby. The koala is also an excellent swimmer.

    They are able to cross rivers to escape from heavy flooding (泛滥).

    English playwright Arthur Wing Pinero said,"Where there's tea, there's hope." Similarly, a Chinese saying goesthat "Firewood, rice, cooking oil, salt, sauce, vinegar and tea are theseven necessities to begin a day."

    Tea is, without doubt, welcomed all overthe world. According to Statista, a German website for statistics (数据), global tea production reached about 5.8million tons in 2018. It has become the most consumed beverage (饮品) in the world – after water, of course.

    According to the UN, tea is much more thanjust a hot drink. It's a big part of many cultures around the world. Youprobably know that people in China use top-grade tea to show respect whenreceiving important guests. Meanwhile, the British tradition of afternoon teais an important part of that country's identity. Making Malaysia's pulled teahas become a sort of art form, where drinkers take pride in its entertainmentaspects.

    Apart from its cultural significance (意义), tea is also a medicine, used from ancienttimes to modern day. "Tea is cold and lowers the fire," Chinese MingDynasty herbalist Li Shizhen once said. The health benefits of tea are stillbeing discovered today: preventing heart disease, obesity and cancer have allbeen linked to drinking green tea, according to the National Center forBiotechnology Information in the US.

    Hot or cold, bagged or loose-leaf,teais more than a drink– it's a social custom and also a magic medicine, alink to the past and a way of life.

Over the past few years, East Asia has seen a huge rise (大幅上升) in the rate of short- sightedness (近视率). Long school days are leaving children with little time to enjoy sunshine. Too little light may cause short- sightedness.

East Asia began its economic (经济的) rise in the 1960s. After that, short- sighted- ness became common in the area. These days, however, almost every young East Asian is short- sighted. In Singapore, nine in ten school- leavers are short- sighted. In China, the rate of short- sightedness among its middle school students has risen to nearly 80 percent.

At the same time, the West isn't staying out of trouble either. One study in California, for example, found a rate of 59 percent among the state's 17 to 19- year- olds.

However, there may be worse things to meet with. Short- sightedness is a lifelong prob- lem, because people with poor eyesight are more likely to have eye problems later in life. This will probably have a bad influence on the future of a country.

Giving students more time outside can cut down the number of children who will become short- sighted. Some wise governments have decided to make sure that their kids are spend- ing more time outdoors.

Tests are important for learning. Many students do well with their homework. {#blank#}1{#/blank#} Here are some tips for you to do well in tests.

Find the Perfect Place

If you study in a place with good lighting, you will feel comfortable. However, the most important thing is that there are no distractions(分心). Try turning off the TV or putting away your smartphone for one hour. {#blank#}2{#/blank#}

Try Study Aids

Every student should take notes and do revision. However, that may not be enough. If you like flashcards, try dividing your notes into different parts. {#blank#}3{#/blank#} They may help you remember the key points too!

Stay Positive and Calm

{#blank#}4{#/blank#} When taking the test, take a quick look through the whole test paper first. If you come across a difficult question, do not be nervous. Stop and think for a moment.

Keep on Studying

Here comes the most important tip: Never give up. {#blank#}5{#/blank#} You will certainly do better in the next test.

Everyone wants to have a good friend, and wants to keep friendship for long. Then what can we do to keep friendship for a long time? Friendship is like a seed (种子). If all the conditions (条件) are right and you really look after it well, then you'll have a strong plant. It will go on to grow bigger and better as time passes by. If it's what you want, keep the advice in mind. 

Spend time around people you'd like to be friends with, and join in with their plans. If you don't agree with their plans, say no in a friendly way, "I like that idea but maybe we could …"

 Be a good listener, so that others know that you're really interested in what they're saying. 

Get to know people well by sharing"safe (安全的)" ideas with them first. It might be something about TV shows or your favourite football team. It isn't always safe to tell someone very personal things about yourself, like things you might be worried about or afraid of. 

Be positive! Don't feel sad about something terrible, and you learn how to deal with sadness. Talk about the good things in your life. No one wants to be troubled by problems all the time. 

The most important thing is that you have to be a good friend if you want a good friend.
