When treating some friends to dinner, we Chinese often say, “The dishes are not good. Please forgive me.” In fact, it is a Chinese way of {#blank#}1{#/blank#} (be) modest. {#blank#}2{#/blank#} he really means is that all the dishes here are really wonderful! What he really hopes is compliment from the guests! But {#blank#}3{#/blank#} English would not understand it at all! Now that it is not very good, why should you present the dishes in front of us? The English would say to their guests “ Enjoy yourselves!” when eating and “hope you've enjoyed!” after eating.

    While {#blank#}4{#/blank#} (eat), we Chinese often say to the guests, “Eat slowly.” This would be very {#blank#}5{#/blank#} (puzzle) to the foreigners: Am I eating very violently? Am I eating too {#blank#}6{#/blank#} or too much?

    And now comes the end of the dinner when your guests {#blank#}7{#/blank#} (leave). The Chinese would say, “Walk slowly!” This is a very polite saying in Chinese, but will also be confusing to the foreigners: why can't I walk fast? Does it matter {#blank#}8{#/blank#} I walk slowly or not? Are you worrying that I may fall over? {#blank#}9{#/blank#} change your words {#blank#}10{#/blank#} a simple “Bye!” or “See you next time!”

    Most people nowadays are so busy with their lives that they do not have time to enjoy a healthy and {#blank#}1{#/blank#} (balance) diet. For most individuals, as {#blank#}2{#/blank#} result of eating foods rich in fats and sugar several years, they choose to go on a diet but do not succeed at the end. Be sure to be with a strong {#blank#}3{#/blank#} (aware) that you are {#blank#}4{#/blank#} you eat! Therefore, maintaining a healthy diet not only {#blank#}5{#/blank#} (provide) your body with energy but also numerous health benefits. One is that you will keep a healthy weight and is also the easiest and most {#blank#}6{#/blank#} (benefit) way in which you can be energetic and protect yourself {#blank#}7{#/blank#} a number of diseases when growing old. Another benefit is that you will meet your everyday nutritional {#blank#}8{#/blank#} (require). {#blank#}9{#/blank#} (basic) speaking, you should ensure that you take the good amount of vegetables, grains, milk and proteins. In most cases, a healthy diet can help you decrease the risk of {#blank#}10{#/blank#} (get) some diseases like diabetes and cancer.

    There was a man who had four sons. He hoped his sons could learn not to judge things too quickly. So he gave them a task in turn,{#blank#}1{#/blank#} (ask) them to go to see a pear tree at a distance{#blank#}2{#/blank#}(separate).

    The first son set out in winter, the second in spring, the third in summer, and the{#blank#}3{#/blank#}young)in autumn.

    When all of them returned home, they were called together{#blank#}4{#/blank#}(describe) what they had seen. The first son complained the tree was{#blank#}5{#/blank#} (bend) and ugly. The second son said the tree was covered with buds(花蕾)and full of hope. The third son said it was full of flowers{#blank#}6{#/blank#}smelled so sweet and that he had{#blank#}7{#/blank#}seen such beautiful scenery. The last son disagreed{#blank#}8{#/blank#}all or them, saying it was filled with fruits, full of life and content.

    The man told his four sons that they were all correct, but they only saw the tree in{#blank#}9{#/blank#}season, He taught them that the value of a person could only be measure when all the seasons were over.

    If you give up in winter, you{#blank#}10{#/blank#}(miss) the hope of spring, the beauty of summer, and the harvest of autumn in your life.

    When I was in primary school, I didn't like going to school. I had {#blank#}1{#/blank#} (difficult) in reading and writing and I always could not answer the teacher's questions {#blank#}2{#/blank#} (correct). I cried a lot because I {#blank#}3{#/blank#} (laugh) at by my classmates. My parents would always get mad at me. I felt very upset and didn't have any interest{#blank#}4{#/blank#} study.

    But then one day, I decided{#blank#}5{#/blank#} (change) my attitude towards study. {#blank#}6{#/blank#}I ended up paying more attention in class and I started to practice my vocabulary and spelling skills. Also, I always {#blank#}7{#/blank#} (go) to my teachers to ask for help when I had any trouble. I started to do better in Grade 3. {#blank#}8{#/blank#}I was in Grade 4, I was still improving. By Grade 5, I had become the top student in class.

    Now as I am {#blank#}9{#/blank#} senior high school student, I know it might be difficult at first. But I like my past in primary school, I know if I keep working and don't give up I will be {#blank#}10{#/blank#} (success).

    Just like every technological advancement, the next is set to be a huge deal, and such is the case for 5G.The wireless technology {#blank#}1{#/blank#} (expect) to power self-driving cars, virtual reality, smart {#blank#}2{#/blank#} (city), and networked robots. {#blank#}3{#/blank#} (research) from King's College London who have joined with Ericsson (ERIC) to dream up futuristic applications for 5G have looked at everything from music {#blank#}4{#/blank#} medicine.

    The team is working towards using {#blank#}5{#/blank#} technology to transfer physical skills across networks and creating what they are calling the “Internet of Skills”. “With 5G and the new networking architecture we're building, we're hoping to get this delay down to just the speed of light,” said Mischa Dohler, a professor of wireless communications at King's College.

    Furthermore, 5G will {#blank#}6{#/blank#} (hopeful) allow a surgeon with virtual reality equipment {#blank#}7{#/blank#} (work) on the other side of the world via a robot. They will use haptic (触觉的) gloves, {#blank#}8{#/blank#} will allow the surgeon to sense motion and pressure when {#blank#}9{#/blank#} (operate) on a patient and can get instant feedback via the gloves.

Meanwhile, Dohler does not expect this to happen overnight and {#blank#}10{#/blank#} (believe) it could take the “Internet of Skills” another decade before it is fully functional.

    Happiness can {#blank#}1{#/blank#}(describe) as a positive mood and a pleasant state of mind. There are many factors contributing to happiness.

A person {#blank#}2{#/blank#} an obviously ideal situation is not necessarily happy. The ideal situation may have little to do with his actual feelings.

A good education and income are usually considered necessary for happiness. Though both may contribute, {#blank#}3{#/blank#} are only chief factors if the person is {#blank#}4{#/blank#}(serious) undereducated or actually suffering from lack of physical needs.

    The rich {#blank#}5{#/blank#}(be) not likely to be happier than the middle-income group or even those with very low incomes. People with college educations are somewhat happier than those who did not graduate from high school, and it is believed that this is mainly {#blank#}6{#/blank#} they have more opportunity to control their {#blank#}7{#/blank#}(life). Yet people with a high income and a college education may be {#blank#}8{#/blank#}(little) happy than those with the same income and no college education.

    Poor health does not rule out happiness except for the severely {#blank#}9{#/blank#}(disable) or those in pain. Learning {#blank#}10{#/blank#}(cope) with a health problem can contribute to happiness.
