The skin is {#blank#}1{#/blank#} essential part of your body and its {#blank#}2{#/blank#} organ. You have three {#blank#}3{#/blank#} of skin which act as a barrier {#blank#}4{#/blank#} disease, poisons and the sun's harmful rays. The {#blank#}5{#/blank#} of your skin are also very {#blank#}6{#/blank#}: it keeps you warm or cool; it prevents your body from {#blank#}7{#/blank#} too much water; it is where you feel cold, heat or pain it gives you your sense of {#blank#}8{#/blank#}. So you can imagine, if your skin gets {#blank#}9{#/blank#} it can be very serious. First aid is a very important first step in the {#blank#}10{#/blank#} of burns.

    Babies are great and lots of fun. We all love babies and we need babies, too. Many countries don't have enough of them. That's a big problem.

    Most babies grow up to become workers. As the number of workers {#blank#}1{#/blank#} (grow), a country can produce more things. That often means people's lives become easier and more {#blank#}2{#/blank#} (comfort). But without enough babies, a country {#blank#}3{#/blank#} (gradual) gets old. Many countries provide services {#blank#}4{#/blank#} their people like health care. These services {#blank#}5{#/blank#} (pay) for by young working people. But they are mostly used by old people {#blank#}6{#/blank#} aren't working any more. Without enough young people, countries can't afford these things.

    Countries are dealing with {#blank#}7{#/blank#} problems in different ways. Many countries are encouraging people {#blank#}8{#/blank#} (have) more babies. Since raising children is expensive, some countries give families extra money. Some other countries change rules {#blank#}9{#/blank#} it is easier for mothers to study and work. Others are welcoming immigrants (移民) from other{#blank#}10{#/blank#} (place). How do you think this problem should be solved?

    The information I {#blank#}1{#/blank#}(collect) over the last few years leads me to believe that speed reading may be less {#blank#}2{#/blank#}(use) than most people think. The claim that you can read and comprehend over 30,000 words per minute is overstated. One researcher proved this in a study where irrelevant and illogical sentences were added to a text. The “speed readers” {#blank#}3{#/blank#} were tested didn't notice the irrelevant lines — the non-speed readers spotted them immediately.

    I've interviewed people who have attended the introductory sessions {#blank#}4{#/blank#} (offer) by some speed reading courses. {#blank#}5{#/blank#} (them) stories indicate that improper methods are sometimes used to sell the courses. Here's how: First, you're asked to read a passage from a book {#blank#}6{#/blank#} which most persons would be unfamiliar. Your reading speed and comprehension are tested during this exercise. Then, after about half {#blank#}7{#/blank#} hour of instruction, another reading test is given. But this time the reading is one most educated Americans know well — such as Huckleberry Finn. Not {#blank#}8{#/blank#} (surprising), persons attending these introductory sessions find that their “exit” speed and comprehension are better than their “entry”{#blank#}9{#/blank#} (perform).

    I'm one of the fiction readers who appreciate the beauty in good writing. Occasionally I'll read a passage or sentence over and over just {#blank#}10{#/blank#} (let) the beauty of its construction soak(参透) in. Good writing must be read carefully and thoughtfully to be fully appreciated.

    Are you sometimes a little tired {#blank#}1{#/blank#} sleepy in the early afternoon? Many people feel this way after lunch. They may think that eating lunch is the cause of the sleepiness. Or, in summer, they may think it is the heat. However, the real reason lies inside their bodies. At that time——about eight hours after {#blank#}2{#/blank#} (wake) up——your body temperature goes down. This is what makes you slow down and feel sleepy. Scientists have tested sleep habits in experiments in {#blank#}3{#/blank#} there was no night or day. The people in these experiments almost always {#blank#}4{#/blank#} (follow) a similar sleeping pattern. They slept for one long period and then for one short period about eight hours {#blank#}5{#/blank#}.

    In many parts of the world, people take naps {#blank#}6{#/blank#} the middle of the day. This is {#blank#}7{#/blank#} (especial) true in warmer climates, where the heat makes it difficult {#blank#}8{#/blank#} (work) in the early afternoon. Researchers are now saying that naps are good for everyone in any climate. A {#blank#}9{#/blank#} (day) nap gives one a more rested body and mind and therefore is good for health in general. In countries where naps are traditional, people often suffer less from {#blank#}10{#/blank#} (problem) such as heart disease.

    The Wandering Earth is a Chinese science fiction movie, {#blank#}1{#/blank#} is based on the novel of {#blank#}2{#/blank#} same name by Liu Cixin, and was released on February 5, 2019, the Chinese New Year's Day.

    After learning the sun is dying out ,people all around the world feel {#blank#}3{#/blank#} (panic), so they build giant planet thrusters(星球推进器) to move the earth out of its orbit and sail {#blank#}4{#/blank#} to a new star system. The 2500 years' journey comes with unexpected dangers, but in order to save humanity, a group of young people come out bravely and fight hard for everyone's {#blank#}5{#/blank#}  (survive).

    We {#blank#}6{#/blank#}(impress) to see the theme of this film. It does not particularly show somebody's ability to save our world {#blank#}7{#/blank#} shows all the human beings are working together,  {#blank#}8{#/blank#} (spare) no effort to save this world.

    The Wandering Earth is seen by people {#blank#}9{#/blank#} the dawn(开端) of Chinese science fiction movies. It means that China's sci-fi movies have {#blank#}10{#/blank#} (official) set sail.

    When I left for the United States to study, I had butterflies in my stomach. I was nervous because I was going to {#blank#}1{#/blank#} new place with new people and new customs. I couldn't even understand {#blank#}2{#/blank#} (they) language. Everything was different {#blank#}3{#/blank#} my own country. There was nobody that I could talk to. I just had my husband, {#blank#}4{#/blank#} was a new person for me, too.

    It was a sad moment when I had to say goodbye to my family and friends. I didn't want {#blank#}5{#/blank#} (leave) my hometown because I grew up there and had wonderful {#blank#}6{#/blank#} (memory) of the place. So, {#blank#}7{#/blank#}(think) about all these changes made me nervous and I was {#blank#}8{#/blank#} (worry) about my new life. But studying abroad was a {#blank#}9{#/blank#}(decide) that I made myself. I had to continue and accept the challenge. I looked forward to {#blank#}10{#/blank#} (visit) my family in the summer vacation.
