Born in England in 1944, Ian Wilmut{#blank#}1{#/blank#}(know)as the leader of the research group that first cloned a female lamb {#blank#}2{#/blank#}(call)Dolly in 1996. Dolly became famous and pictures of her appeared on the{#blank#}3{#/blank#}(cover)of magazines all over the world. The{#blank#}4{#/blank#}(possible)of reproduction without a male and female being involved also made her the focus of a moral debate. For scientists, however, the cloning of dolly using the DNA of an adult cell was a breakthrough {#blank#}5{#/blank#}showed the cloning of special animals was possible.

    However,{#blank#}6{#/blank#}Wilmut thinks unlikely is human cloning. He says {#blank#}7{#/blank#}(undertake)the procedure with humans would require 29 surrogate(替代的)mothers and 300 eggs. Of those 29,28 would be bound {#blank#}8{#/blank#}(experience)failure and suffer physically and emotionally. He says he is also concerned about the psychological and{#blank#}9{#/blank#}(society)consequences a cloned might have to go through. For these reasons, he is not {#blank#}10{#/blank#}favor of it.

There has been a recent trend in the food service industry toward lower fat content and less salt. This trend,{#blank#}1{#/blank#}was started by the medical community(医学界) as a method of fighting heart disease, has had some unintended side{#blank#}2{#/blank#}(effect) such as overweight and heart disease—--the very thing the medical community was trying to fight.

    Fat and salt are very important parts of a diet. They are required to process the food that we eat, to recover{#blank#}3{#/blank#}injury and several other bodily functions. When fat and salt{#blank#}4{#/blank#}(remove) from food, the food tastes as if it is missing something.

    As{#blank#}5{#/blank#}result, people will eat more food to try to make up for that something missing. Even{#blank#}6{#/blank#}(bad), the amount of fast food that people eat goes up. Fast food{#blank#}7{#/blank#}(be) full of fat and salt; by{#blank#}8{#/blank#}(eat) more fast food people will get more salt and fat than they need in their diet.

    Having enough fat and salt in your meals will reduce the urge to snack(吃点心) between meals and will improve the taste of your food. However, be{#blank#}9{#/blank#}(care) not to go to extremes. Like anything, it is possible{#blank#}10{#/blank#}(have) too much of both, and this is not good for your health.

    Some new car models are fashionable. Others can go a long way with only a little gas. But all are taking advantage of technology that is making driving safer and {#blank#}1{#/blank#}(easy).

    The new Ford Escape has technology that helps the car avoid crashes. A new control system changes the car's speed {#blank#}2{#/blank#} (keep) a safe distance from other cars on the road. It works {#blank#}3{#/blank#}using sensors that measure the Escape's distance from other vehicles.{#blank#}4{#/blank#}(drive) can connect to the Ford Escape's electronic system with their smartphone. The phone can start and track their car from anywhere.

    {#blank#}5{#/blank#}emergency vehicles are near, the Heedful Audio Alert System, or HAAS, will warn drivers. The device has a sensor{#blank#}6{#/blank#}detects（发现）the sound of an emergency vehicle siren（汽笛）. The device then {#blank#}7{#/blank#}(send) a warning to the driver's phone.

    A company {#blank#}8{#/blank#}(call) Sober Steering has developed a device to stop drunken drivers. The device can detect alcohol in the skin. If the driver's alcohol level is too high, {#blank#}9{#/blank#}will shut down the vehicle.

    Just as technology is changing life at home and at work, it {#blank#}10{#/blank#}(change) life on the road as well.

    China's homegrown sci-fi blockbuster (大片) The Wandering Earth scored at the Spring Festival box office. The film is an {#blank#}1{#/blank#}  (adapt) of a novel of the same name by Liu Cixin, author of the Hugo Award-winning The Three-Body Problem. As {#blank#}2{#/blank#}  (it) visual effects impress a global audience, a united human community when {#blank#}3{#/blank#}  (face) a big disaster gets attention too.

    Director Guo Fan said that he {#blank#}4{#/blank#} (conscious) avoided making a do-it-alone superhero; instead, the fight to save Earth {#blank#}5{#/blank#} (fight) by all humans. In The Wandering Earth, mankind is threatened by a dying sun, {#blank#}6{#/blank#} forces them to go on a generations-long space journey to look for a new one. At {#blank#}7{#/blank#} center of the story are a Chinese astronaut and his son, who join a global task {#blank#}8{#/blank#} (prevent) Earth from crashing into Jupiter. At the end of the film {#blank#}9{#/blank#}(come) international rescue teams who help the Chinese team and give a final try to save Earth.

    One online review reads, "It fits the Hollywood standard on presentation and visual effects, but the themes of family and love of homeland are typical {#blank#}10{#/blank#} Chinese sci-fi films."

How to achieve a healthy lifestyle

    We all know that it is good to live a healthy life. {#blank#}1{#/blank#} (live) a healthy life means we should eat healthy food. Yet for many of us keeping a healthy lifestyle is very difficult. Part of this is because we are creatures of habit.

    So if you want {#blank#}2{#/blank#} (live) a healthy life, you have to change your habits that are not so healthy. In order to feel less tired, you have to replace your habit of sleeping only 4 hours a day with sleeping at least 6 hours a day.

    Now when most people decide to live a more healthy life, they try to deal with all of their habits all at once. Take losing weight {#blank#}3{#/blank#} example. They go on {#blank#}4{#/blank#} quite strict diet, and yes, they do lose weight, sometimes a lot of weight in a short period. But they do not really change their eating habits. So these people often notice they will gain the weight {#blank#}5{#/blank#} and more even, once they stop the diet.

    And the same holds true for these people. They start exercising in order to lose weight or to overcome a physical problem. Once the weight has been lost or the problem has been overcome, many stop {#blank#}6{#/blank#} (exercise). It has not become a habit.

    In fact, a lot of people don't look forward to {#blank#}7{#/blank#} (create) these habits, such as eating breakfast, regular physical exercise and enough sleep. People complain these habits are so {#blank#}8{#/blank#} (bore) and difficult to achieve that they have {#blank#}9{#/blank#} (little) time to spend on things they like to do. So people should change their attitudes first. What if you thought of chocolate as a kind of boring food? What if you thought of physical exercise as something {#blank#}10{#/blank#} (relax)?

    From his first day of preschool to his last day of high school, he was looked at{#blank#}5{#/blank#}(strange)by others. People would call him names like "cyclops(独眼龙)" and would tell him that he was {#blank#}6{#/blank#} mistake. Along with this, suffering from obsessive compulsive disorder(强迫症)made it difficult for him{#blank#}7{#/blank#}(do)normal activities.

    In 2016 he graduated from high school with the support of a loving family {#blank#}8{#/blank#} the help of teachers and friends. He began to write a book and a year later he completed his book.
