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．

Dear Dad,

    On this date of your 50th birthday, Mom gave me the letter you wrote me when I was born 18 years ago. In your letter, you {#blank#}1{#/blank#}(wish) me to be strong-minded and successful. You were looking forward to {#blank#}2{#/blank#}(see) me fight for my future bravely and do well for {#blank#}3{#/blank#} and others.

    After reading this letter, I feel quite {#blank#}4{#/blank#}(shock) at your{#blank#}5{#/blank#}(expect) on me. I also feel shamed {#blank#}6{#/blank#}not having performed well to meet your demand. I still remember when I was in primary school, I failed to apply myself to studying. I was addicted to computer games. As a consequence, I soon became the last one in my class. You didn't abuse me at all. {#blank#}7{#/blank#}the contrary, you taught me that studying was the most important object at the moment and encouraged me to study hard. Only {#blank#}8{#/blank#}I read your letter did I realize that I behaved so badly at that time and you were so sad to see I didn't do well for myself.

    I can't help expressing my gratitude and sending my best wishes to you. Wish you{#blank#}9{#/blank#}(health) and happy. I promise that I will spare no effort to satisfy your demand of being {#blank#}10{#/blank#}brave and successful person.

    The sun at the center of our Solar System is one of the big reasons for{#blank#}1{#/blank#}we're here today, but it can also be a big trouble from time to time. Coronal mass ejections(CMEs) (日冕物质喷发)can seriously damage human{#blank#}2{#/blank#}(communicate) systems.

    For years, researchers{#blank#}3{#/blank#}(attempt) to forecast and predict CMEs in {#blank#}4{#/blank#}hope that warnings could help prevent damage to electronics and the power grid (电网). As it turns{#blank#}5{#/blank#}that a CME is more like a sneeze. Professor Mathew Owens of the University of Reading explains, "The research team and I have found they are more like an{#blank#}6{#/blank#}(expand) dust cloud or sneeze."

    When the solar wind acts on the CME as it moves through space, it causes the shape and behavior of the energy explosion {#blank#}7{#/blank#}(become) unpredictable. "Therefore if we want to protect{#blank#}8{#/blank#} (we) from solar eruptions, we need to understand more about the solar wind, "Owens says.

    The research team suggests that solar wind readings should {#blank#}9{#/blank#} (include) in the forecasting and prediction of future CMEs. This study could help scientists more{#blank#}10{#/blank#}(accurate) assess the risk that the ejections bring to human technology and potentially help reduce the damage they cause.

    A CCTV joumalist succeeded in arousing a heated discussion among citizens by asking people {#blank#}1{#/blank#} they were happy. The responses to the question were{#blank#}2{#/blank#}(variety), even some quite hinny ones included. Although people played jokes on the answers, it did not take long{#blank#}3{#/blank#} they began to figure out the true meanings 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{#blank#}5{#/blank#} decrease in the number of those who are voluntarily at the mercy of wealth. Some people whose intention is {#blank#}6{#/blank#}(make) big money appreciate being given any chance to multiply their income, believing that is{#blank#}7{#/blank#}their happiness lies. Some arc eager to inherit (继承) their parents' property, especially those who {#blank#}8{#/blank#} (be) known as silver-spoon kids (富二代).Even worse, some would rather break the law to satisfy their financial desire or seek their fortune {#blank#}9{#/blank#} (legal).

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

Photographers Turn Their Cameras on Pets

In 2019 photographers Kendrick Brinson and David Walter Banks visited 14 countries on assignment. When the couple described the adventures {#blank#}1{#/blank#}they had experienced when photographing, people invariably asked, "But who takes care of your four cats and dogs?" They joked that the pet siter made a lot of money.

But 2020 couldn't have been {#blank#}2{#/blank#}(different). Due to COVID-19, Brinson and Banks never left the United States. Often, they didn't even leave their Los Angeles neighborhood. {#blank#}3{#/blank#} {#blank#}4{#/blank#}spending long hours in airport security lines and waiting-for the perfect lighting, the pair stayed along with dogs Tux and Tia and cats Rex and Kudzu. "Our pets became emotional therapy animals, and our only friends we could safely hug in a world {#blank#}5{#/blank#}(strike) by a deadly pandemic," Banks said.

As COVID-19 lockdowns swept across the world in March of 2020, the change made an especially great impact on photographers, who are accustomed to {#blank#}6{#/blank#}(spend) long periods abroad. And so many cameras {#blank#}7{#/blank#}(turn) on a domestic subject: the pet.

Research suggests that pets have offered emotional support during the pandemic, helping {#blank#}8{#/blank#}(make) the long days of isolation more bearable, says Emily MeCobb, a clinical associate professor at Cummings School of Veterinary Medicine at Tufts University. In fact, the pandemic has sped up a trend, according to McCobb's and other scientists' observation, {#blank#}9{#/blank#} the pet is becoming a member of the family. "In the past 20 to 30 years, the role of the pet in the family {#blank#}10{#/blank#}(take) on a whole new role," says MeCobb." It really hasn't been that long {#blank#}11{#/blank#}these furry child substitutes gained this kind of importance in American society."
