    However, people from places like Spain, Italy or south American countries approach others closely and are more {#blank#}8{#/blank#} to touch them.

    In {#blank#}9{#/blank#} , though, studying international customs can certainly help avoid difficulties in today's world of cultural {#blank#}10{#/blank#} .

    The "selfie" is used to describe the self-taken photo,often from a smartphone. Someone takes about 10 selfies each time he does, and he only ends up{#blank#}1{#/blank#} (post) one or two of those. He picks the one that he feels make him look the {#blank#}2{#/blank#} (good). In that picture,he gains confidence. For that moment, everything bad or terrible that has happened to him {#blank#}3{#/blank#} (remove), because that smile is what gives him the {#blank#}4{#/blank#} (determine) to love himself.

    I read {#blank#}5{#/blank#} poem recently and the young man said，”If I ask you {#blank#}6{#/blank#} you love, the answers will most likely roll your tongue. You love to read. You love to write. You love your mom, you daughter,or your best friend. How long do you think you can go on and on before you say 'I love{#blank#}7{#/blank#}(I)'？"

    That statement hit me like a ton of bricks. I've struggled with confidence all my life. I still do. And in {#blank#}8{#/blank#} way am I saying that taking a selfie is a gateway {#blank#}9{#/blank#} confidence.{#blank#}10{#/blank#}, the selfie does deserve some credit for allowing individuals to express themselves.

    Anyone who has had a long-term disease knows that recovering at home can be lonely. This can be{#blank#}1{#/blank#}(especial) true of children. They may feel {#blank#}2{#/blank#} (leave) out. Now, these children may have a high-tech friend to help fed less alone. A small robot may help children who are recovering from long-term illnesses. The robot like human beings takes their place at school. And their school friends must help carry the robot between classes and place the robot on their desks.

    Through the robot, a child can hear his or her teachers and friends. He or she can also attend classes from wherever they are recovering—whether at home{#blank#}3{#/blank#}from a hospital bed. Dolva, one of the scientists who {#blank#}4{#/blank#}(be) concentrating on developing the robot, explains{#blank#}5{#/blank#}the robot AVI works. She says from home, the child uses a tablet or phone to start the robot,{#blank#}6{#/blank#} (use) the same device, he or she can control the robot's movements. Inside the robots there is a small computer linked{#blank#}7{#/blank#}a 4G network. The robot is {#blank#}8{#/blank#}(equip) with speakers, microphones and cameras,{#blank#}9{#/blank#}makes communicating{#blank#}10{#/blank#}(easy). So it's the eyes and the cars and the voices at school. Hopefully AVI will help some children feel less lonely while they are absent from class.

    Here, let me share one of my experiences with you. When I was a ten-year-old girl, I was once asked to deliver a speech titled “A Real Test in My Life” before the whole class! Just imagine how {#blank#}1{#/blank#}(terrible) shy I was the moment I thought of that with so many eyes {#blank#}2{#/blank#}(fix) upon me. I had no other {#blank#}3{#/blank#}(choose), though. First I was to draft the speech and that was just a piece of cake for me, because I was a good writer — something to pride myself in. But the hard part {#blank#}4{#/blank#}(lie) in my oral presentation; to read from {#blank#}5{#/blank#} paper was not allowed; I had to give the speech from my memory and in front of such a big audience ! A real trial began when I stood on the platform with my legs trembling and my mind blank. How much time had passed by, I didn't know. My listeners were still waiting, patiently and without any signs of rushing me. Gradually I found {#blank#}6{#/blank#} (I) back，giving out my speech with difficulty. Finally I finished. After {#blank#}7{#/blank#} seemed to be a hundred years, I found my audience applauding. I made it! From then on, my fear of talking before an audience disappeared. Actually with my confidence building {#blank#}8{#/blank#}， I now turn out to be a great speaker.{#blank#}9{#/blank#} (Look) back, I know the greatest difficulty on our way to success is our fear; overcome it，{#blank#}10{#/blank#} we will be able to achieve our goals.

    Overhead bridges are found in many parts of big cities, especially in places{#blank#}1{#/blank#} traffic is very heavy and crossing the road is dangerous. The purpose of these bridges{#blank#}2{#/blank#}(be) to enable pedestrians to cross roads {#blank#}3{#/blank#}(safe). Overhead bridges are used in very much the {#blank#}4{#/blank#}way as Zebra crossings. They are more efficient although{#blank#}5{#/blank#}(little) convenient because people have to climb up a long flight of steps. This is{#blank#}6{#/blank#}(convenient) especially to older people. When pedestrians use an overhead bridge, they do not hold up traffic. However, when they cross a busy road using a zebra crossing, traffic is held up. This is why the government has built many overhead bridges {#blank#}7{#/blank#}(help) pedestrians and to keep traffic moving at the same time. For their own safety, pedestrians should be encouraged to use them instead of {#blank#}8{#/blank#} (risk) their lives by dashing across the road. Old people, however, may find it a little difficult climbing up and down the steps, but it is still much safer than walking across the road with all the danger of moving traffic. Overhead bridges serve a very useful purpose. Pedestrians, both old and young, should make {#blank#}9{#/blank#} a habit to use them. This will prevent unnecessary accidents and {#blank#}10{#/blank#}(lose) of life.

CCTV journalist succeeded in arousing a heated discussion among netizens by asking people whether they were happy. The responses {#blank#}1{#/blank#} the question were various, even some quite funny ones included. Although people {#blank#}2{#/blank#} (play) jokes on the answers, it did not take long {#blank#}3{#/blank#} they began to figure out the true meaning of happiness.

It is certain that people's views on happiness {#blank#}4{#/blank#}(affect) greatly by their own life experience. Unfortunately, too many people refer to being rich as happiness and there is no sign of a decrease in the number of those who are voluntarily at the mercy of wealth. Some people whose {#blank#}5{#/blank#} (intend) is to make big money appreciate being given any chance to increase their income, believing that is {#blank#}6{#/blank#} their happiness lies. Some are eager to inherit their parents' property, especially those {#blank#}7{#/blank#} are known as silver-spoon kids. Even worse, some would rather break the law {#blank#}8{#/blank#} (satisfy) their financial desire or seek their fortune {#blank#}9{#/blank#} (legal).

In my opinion, happiness is not about {#blank#}10{#/blank#} (pursue) wealth but about admiring the beautiful things in life. Therefore, live your life to the fullest and be happy.
