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.

    Memories of my sophomore (高二学生）dance {#blank#}1{#/blank#} (be) still vivid in my mind.

It was 5 o'clock in the afternoon, and I had put on my red party dress and my host mother was doing up my hair. My schoolmate Chris {#blank#}2{#/blank#}(show) up at the front door {#blank#}3{#/blank#} his suit and tie. He handed me a red corsage (小花束）that {#blank#}4{#/blank#} (perfect) matched my dress. We headed for school, and started our dance? To be honest, I am not sure {#blank#}5{#/blank#} I should call what we did “dancing”. We jumped, yelled and laughed with people we knew or had just met for the first time. We twirled in circles, threw our arms in the air and, as my English teacher later put it, ran wild around the place. In those few {#blank#}6{#/blank#} (hour)，nothing seemed to matter {#blank#}7{#/blank#} than having fun.

    With music playing and everybody {#blank#}8{#/blank#} (have) a good time, Chris asked me a question, "How is the dance different from dances in China?"

“Well, we don't usually have dances in China.”

    “What? How do you express {#blank#}9{#/blank#} (you) then?”

    {#blank#}10{#/blank#} (lose) in thought. I was silent for a while.

    Now, I have an idea for everyone: Just dance.

    Each year thousands of{#blank#}1{#/blank#} (explore) and tourists visit the polar regions of the Arctic and Antarctica. But the increasing number of people travelling to the ends of the Earth' can have a negative effect{#blank#}2{#/blank#} fragile ecosystems. Should tourists{#blank#}3{#/blank#}(allow) to visit polar regions?

    About 40,000 tourists visit Antarctica each year, More than five million travel to the Arctic and sub-Arctic. Transporting tourists to the regions {#blank#}4{#/blank#}(increase) ship and airplane traffic, adding to the risk of pollution, oil spills, and other {#blank#}5{#/blank#}(environment) damage. Because the places where wildlife is accessible {#blank#}6{#/blank#}(be) few in numbers, tourist traffic can become concentrated in specific areas,{#blank#}7{#/blank#} (put) Arctic vegetation at risk.

    Others say that access{#blank#}8{#/blank#} these very special parts of the world should not be restricted to only researches and scientist. Polar tourism allows people to develop deep personal connections with polar regions. “Those {#blank#}9{#/blank#}travel to the Arctic or Antarctica often become cheer leaders for supporting those places” Jim Sano, vice president for travel and{#blank#}10{#/blank#}(conserve) at World Wildlife Fund, told TFK.

    I grew up in one of the poorest communities on the south side of Atlanta, US and was raised by a single mother who didn't finish 3rd grade. Not many people expected much of me, so I had to expect something of {#blank#}1{#/blank#}.

    On my 13th birthday, I bought a poster of Harvard and put it up in my room. Being at Harvard was {#blank#}2{#/blank#} I dreamt about all the time though many people thought it was far {#blank#}3{#/blank#} my reach. I would bum the midnight oil,{#blank#}4{#/blank#} (bury) in piles of books. I'd begin my day by asking myself these two questions, "What do I want in my life?" and "Are the things I am doing today going to get me closer to that life?"

    {#blank#}5{#/blank#} (remind) myself of my goal each made it easy to say no to the same choices I saw my peers making, because those paths wouldn't have taken me closer to my goal. Asking myself those questions gave me the courage and energy to study just one more hour on my SATs when my friends were asleep; and it gave me the determination to submit（提交）just one more scholarship {#blank#}6{#/blank#} (apply) when 180 others had already turned me down.

    On March 31st, 2011, {#blank#}7{#/blank#} email arrived from Harvard. The first word was "Congratulations!" A

    month later, Harvard invited me to visit the campus {#blank#}8{#/blank#} for the first time I got to see inside Sanders Theater, tour Widener Library and eat dinner in Annenberg Hall. I couldn't wait to start my {#blank#}9{#/blank#} (explore) here.

    Who you are today is the result of the decisions that {#blank#}10{#/blank#} (make) earlier, and who you will be tomorrow will be the result of the choices you make today. Who do you want to be tomorrow?

    The Moon's near side, the one we all see, has been the target of many robotic and human missions. However, its far side, also {#blank#}1{#/blank#} (call)the dark side because it faces away from the Earth and little {#blank#}2{#/blank#} (know)about it, has never been explored. That changed on Jan.2, 2019, when Chinese spacecraft Chang'e 4 made a soft landing on {#blank#}3{#/blank#} is often referred to as the dark side.

    The landing is {#blank#}4{#/blank#} example of China's growing desire {#blank#}5{#/blank#} (compete)with the American, Russian and European space programs. China also wants to {#blank#}6{#/blank#} (strength)its position as a regional and international power.

    One of the great {#blank#}7{#/blank#} (difficulty)in exploring the far side of the Moon is that it blocks all radio signals, {#blank#}8{#/blank#} (make)it impossible to communicate with the Earth. To overcome this difficulty, in 2017, the Chinese National Space Administration launched a satellite to orbit the Moon and relay the signals. Once a {#blank#}9{#/blank#} (rely)communication path was in place, Chang'e 4 could send back information.

    Chang'e 4 will make astronomical observations and examine the structure and mineral composition of the ground above and below the surface, {#blank#}10{#/blank#} researchers believe will provide insights into the solar system's early days and perhaps even the origin of the first stars.

I was very frightened when{#blank#}1{#/blank#}(wake) up in hospital last Thursday. I fainted in my PE class because of low blood sugar levels. Fortunately, I was rushed to hospital{#blank#}2{#/blank#}(immediate). The doctor helped me and I made a full recovery within two days. My experience proves what a bad idea{#blank#}3{#/blank#}is to try to lose weight by skipping meals. Now I know this extreme weight-loss method has serious side{#blank#}4{#/blank#}(effect). Now I also understand that being healthy and{#blank#}5{#/blank#}(energy) is more important than being slim.

From now{#blank#}6{#/blank#}, I will pay more attention to my health rather than my weight. I will eat a{#blank#}7{#/blank#}(balance) diet to make sure I have enough nutrition. Exercising regularly is also{#blank#}8{#/blank#}important part of a healthy lifestyle. My doctor tells me that it will help me concentrate better in class. So, I{#blank#}9{#/blank#}(play) sport with my friends every other day after school, {#blank#}10{#/blank#}I hope can help me get into shape.
