I seldom thought I had a passion. I would sit before the TV all day, thinking about nothing but the next show. It was not long ago that I first learned how important {#blank#}1{#/blank#} (have) a passion is to life.

    One day I went with Mum {#blank#}2{#/blank#} (drop) my sister off at the gym. Then, as Mum stopped at a red light, someone on the roadside caught my eyes. It was a man {#blank#}3{#/blank#} (dress) in rags, homeless. That didn't interest me, for I {#blank#}4{#/blank#} (see) many like him before.

    But the man wasn't sitting down with a sad {#blank#}5{#/blank#} (express). He had a radio in his hand and was dancing {#blank#}6{#/blank#} (merry) to the music. The radio seemed to be the most precious thing {#blank#}7{#/blank#} he had.

    “Mum, why does that man have a radio even though he is homeless?” I asked.

    “He bought {#blank#}8{#/blank#} ,”she replied.

    “But if he is homeless, why doesn't he use the money to buy food or clothes? He wasted it on something he doesn't need.”

    “Well, Sarah, sometimes food and clothes aren't the only important things. We need happiness, too.”

    “I see.” The man {#blank#}9{#/blank#} care too much about music, so he bought a radio instead of food and clothes. I realized that happiness is the key to life. Without it, there {#blank#}10{#/blank#} (be) nothing to look forward to. A passion a person the happiness he needs to keep going!

    Sally is a good student.She does well in all her{#blank#}1{#/blank#}(subject).You must wonder{#blank#}2{#/blank#}she can study so well.Let me tell you something about her good study habits.

    First,Sally spends two hours{#blank#}3{#/blank#}(study) after school every day.And she always studies from seven to nine on schedule.Sally is a very{#blank#}4{#/blank#}(determine) girl,so nothing can stop her doing that.

    Second,if Sally wants to start studying,first she{#blank#}5{#/blank#}(put) everything that has nothing to do with her studying aside,like the cell phone.And{#blank#}6{#/blank#}(actual) there are only books left on her desk.

    Third,Sally never{#blank#}7{#/blank#}(leave) her problems till next day.When she meets some difficult problems and she can't work{#blank#}8{#/blank#}out,she will make a request to others for help.She doesn't wait{#blank#}9{#/blank#}(do) them next day.

    What do you think of Sally's study habits?You can have a try.I hope they will be{#blank#}10{#/blank#}great help to you.

    Some day, our world may {#blank#}1{#/blank#} (fill) with driverless cars. But.{#blank#}2{#/blank#}will we communicate with them if there's nobody in the driver's seat?

    At present, drivers can make gestures like{#blank#}3{#/blank#} (nod) when they let us cross the street.{#blank#}4{#/blank#} self-driving cars don't have this ability.

    The US car maker Ford and its partner Virginia Tech {#blank#}5{#/blank#} (try) to solve this problem. The team is testing a method {#blank#}6{#/blank#}uses light signals. For example, a slow-blinking tight shows the car is coming to  {#blank#}7{#/blank#}stop, and a rapidly flashing light   tells passers-by that the car is about to speed up.

    {#blank#}8{#/blank#} (test) the method on real roads, the team has designed a special suit that looks like a car scat. When a driver wears it, it appears as if the car were driverless.

    The team has {#blank#}9{#/blank#} (successful) collected more than 1,500 hours of data, which has recorded how people interacted with a “driverless” car. Ford says it plans to share the data {#blank#}10{#/blank#} 11 other car makers, which should lead to a signaling system that will be used in every driverless car.

    Johnny Carson began his career in television in his {#blank#}1{#/blank#} (twenty). First he worked at local stations in Nebraska. Several years {#blank#}2{#/blank#} (late), he moved to Los Angeles, California. It was “The Tonight Show” {#blank#}3{#/blank#} made Johnny Carson famous for thirty years. He became {#blank#}4{#/blank#} most popular star of American television. He{#blank#}5{#/blank#} (call) “the king of late night”. Critics  (评论家) said Americans from all parts of the country liked him and {#blank#}6{#/blank#} (feel) they knew him. He did not take his fame {#blank#}7{#/blank#} (serious). Carson's special skill was his sense of humor. Audiences laughed at his jokes {#blank#}8{#/blank#} he made at the beginning of his show. However, sometimes they laughed even {#blank#}9{#/blank#} (hard) at the jokes that failed. He was the most powerful performer on television. Many comedians and singers became successful after {#blank#}10{#/blank#} (appear) on “The Tonight Show”.

    I won't call myself the most accomplished person when it comes to {#blank#}1{#/blank#} (hold) chopsticks. In fact, I'm pretty sure that my technique looks clumsy at times. I tend to hold {#blank#}2{#/blank#} (I) in the middle, more beginner than expert.

    Still, since I eat almost every meal with the eating utensil(器皿)of choice in China it's not uncommon for a new friend or acquaintance to come to a simple {#blank#}3{#/blank#} (conclude) after observing me that my Chinese husband, Jun, must {#blank#}4{#/blank#} (show) me how to use them.

    They are wrong. I've used chopsticks ever since I was a teenager, a time when my sister and mother were both fond of Chinese cuisine and introduced me {#blank#}5{#/blank#} many new dishes, along with the {#blank#}6{#/blank#} (prefer) utensils in China. We always kept bamboo chopsticks along with our {#blank#}7{#/blank#} (knife), forks and spoons, ready for whenever we happened to have Chinese food for dinner. It was my closest family {#blank#}8{#/blank#} observed my first mistakes I made in using chopsticks.

    Plus, I lived over two years in China before Jun and I started dating and I {#blank#}9{#/blank#} (expect) to use chopsticks in almost every restaurant, stand and bar. Trust me, when you're hungry you figure out pretty fast what it takes to down(咽下) {#blank#}10{#/blank#} meal with these utensils.
