There has been a recent trend in the food service industry toward lower fat content and less salt．This trend，which was started by the medical community（医学界）{#blank#}1{#/blank#} 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{#blank#}3{#/blank#}（process） the food that we eat，to recover from injury and for 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 to have too much of both，{#blank#}10{#/blank#} is not good for the health．

    How would you feel if you woke up and found your entire computer's contents — including your photos, your recent documents — no longer {#blank#}1{#/blank#}(access)? What if you found out that they had {#blank#}2{#/blank#}(wipe) from your computer, leaving you with nothing but heartache?

    Guess what? It happens to people every single day. Every day, people across the country head into their local Apple store in {#blank#}3{#/blank#}(tear), broken computer in hand, praying as they wait in line that {#blank#}4{#/blank#}expensive repair might, just might, recover {#blank#}5{#/blank#}priceless, irreplaceable files. A few get lucky. But for the rest, there's nothing anyone can do {#blank#}6{#/blank#}(help).

    Hasn't happened to you? If your computer{#blank#}7{#/blank#}(remain) unprotected, it will, and it's only a matter a time. But thanks to recent breakthroughs in computer backup technology, you now have a number of options to prepare, and if you're smart, when your computer{#blank#}8{#/blank#}(crash), you shouldn't have any problem {#blank#}9{#/blank#}(get) 100% of your files back that same day. I'm not talking about an external hard drive. I'm talking about an online backup {#blank#}10{#/blank#}(solve) that runs quietly in the background on your computer. If you have one installed, when your computer crashes, you'll be just one click away from bringing your files back to life.

    Throughout modern history, perhaps there has never been a scientist as iconic (偶像的) as Stephen Hawking.

    Whether he{#blank#}1{#/blank#}(educate) the world with his knowledge of the universe, or making fun of himself in TV shows, it is hard to imagine what the world will be like now Hawking is no longer in.

    On March 14, 2018, the British physicist passed away in Cambridge. Since then, many people have expressed their condolences (哀悼) on social media, including British computer scientist Tim Berners-Lee{#blank#}2{#/blank#}invented the World Wide Web. “We have lost a great mind and a wonderful spirit,” Berners-Lee wrote.

    Hawking was an icon for many reasons, but he will be best remembered {#blank#}3{#/blank#} his work in the field of science.

    Building on German scientist Albert Einstein's work, Hawking explained his belief that space{#blank#}4{#/blank#} (start) with the Big Bang, and will end with black holes.

“This complete set of laws can give us the {#blank#}5{#/blank#} (answer) to questions like 'How did the universe begin?'” Hawking wrote in his 2010 work The Grand Design. “Where is it going and will it have an end? If so, how will it end?”

    Besides his work in science, he also managed to overcome many difficulties in his personal life. While{#blank#}6{#/blank#} (study) at Cambridge University, he was diagnosed with motor neuron (运动神经元) disease at the age of 21. His {#blank#}7{#/blank#} (ill) left him paralyzed and he was told he only had a short time to live. However, he went on to become one of the{#blank#}8{#/blank#} (great) minds the world has ever known.

    “I felt it was unfair. Why should this happen to me?” he once recalled. “At the time, I thought my life was over and that I would never realize the potential I felt I had. But now, 50 years later, I can be satisfied with my life.”

Hawking left behind a great legacy (遗产). His signature book A Brief History of Time: From the Big Bang to Black Holes{#blank#}9{#/blank#}(publish) in 1988, became one of the world's best-selling science publications. And in 2014, UK actor Eddie Redmayne played Hawking in the movie The Theory of Everything, which tells the tale of the physicist's life.

    He may no longer be with us{#blank#}10{#/blank#} Hawking will continue to inspire the world for generations to come. As he once said himself, “Look up at the stars and not down at your feet!”

    Many kinds of dinosaurs' bones {#blank#}1{#/blank#}(find) recently by Chinese scientists in Nanyang county, Henan Province. {#blank#}2{#/blank#} the scientists inspected the bones, they were surprised {#blank#}3{#/blank#}(spot)) these dinosaurs could not only run {#blank#}4{#/blank#}the others but also climb the trees.

    Dinosaurs died {#blank#}5{#/blank#} suddenly around 60 million years ago. Some scientists think {#blank#}6{#/blank#}came after an {#blank#}7{#/blank#}(expect) incident when a huge rock from space hit the earth {#blank#}8{#/blank#} put too much dust into the air. Others think the earth got too hot for the dinosaurs to live on any {#blank#}9{#/blank#}(much). Nobody knows {#blank#}10{#/blank#}sure why and how dinosaurs disappeared from the earth in such a short time.

    Starting this September, freshmen at Tsinghua University will have to take swimming courses. They won't receive their degrees until they pass the test{#blank#}1{#/blank#}(success). Exceptions will be allowed for students with certain physical or mental conditions, if{#blank#}2{#/blank#}(prove) by medical staff.

    Actually, viewing the ability{#blank#}3{#/blank#}(swim) as a must for students is not something new to this university. It was a{#blank#}4{#/blank#}(require) in the early 20^th century. Later it{#blank#}5{#/blank#}(drop) due to a rising number of students and a lack of facilities（设施）.

    As for {#blank#}6{#/blank#}new rule, opinions vary greatly. Some students welcome it, saying it's a necessary skill {#blank#}7{#/blank#}can save lives, while others argue that it's not reasonable to link degrees {#blank#}8{#/blank#}swimming ability.

    In response to the negative reviews, Liu Bo, head of the Division of Sports Science, gave the following explanation. {#blank#}9{#/blank#}a water sport, swimming does less harm to joints（关节）and muscles and is helpful in improving students' endurance.{#blank#}10{#/blank#}(consequence) it's beneficial to students in the long run.

    Mochi (年糕) is a traditional food popular in Chinese and Japanese cooking, made from {#blank#}1{#/blank#} (special) treated rice. It is often presented in the form of a round cake, and is traditionally exchanged at the New Year.

Mochi is made by {#blank#}2{#/blank#} (put) sticky rice into water overnight, cooking it and pounding it into a sticky paste. The paste is made into shapes ranging from simple to complex rounds, some of {#blank#}3{#/blank#} are stuffed with sweet fillings. Mochi is often decorated with {#blank#}4{#/blank#} (flower) or fruits, especially when it is exchanged as {#blank#}5{#/blank#} gift at celebrations like birthdays and the New Year.

    Traditionally, wooden mortars (臼) and pestles (杵) {#blank#}6{#/blank#} (use) to pound mochi rice. Fresh mochi is usually cooked and served warm {#blank#}7{#/blank#} a variety of sauces. Steaming and boiling are both popular preparations in Japan, along with cooking. Fresh mochi is soft but it{#blank#}8{#/blank#} (hard) quickly. Prepacked mochi blocks, flattened and cut into square pieces or shaped into rounds, are available at grocery stores. Mochi can go bad easily, so it's {#blank#}9{#/blank#} (good) to cook soon than to keep it in your fridge.

    Hard mochi pieces can be cooked, deep-fried, boiled, and more. Cooked mochi is very sticky, so be careful not {#blank#}10{#/blank#} (choke) on it.
