One day, a poor boy who was trying to pay his tuition for school by selling goods door to door found that he only had one dollar {#blank#}1{#/blank#} (leave). He was hungry so he decided to beg for a meal at the next house.

    However, he suddenly felt very {#blank#}2{#/blank#} (shame) when a lovely young woman opened the door. Instead of a meal he asked for a drink of water. She thought he looked hungry so she brought him {#blank#}3{#/blank#} large glass of milk. He drank it hurriedly, and then asked, “How much do I owe you?”

 “You don't owe me anything,” she replied, {#blank#}4{#/blank#} (smile). “Mother {#blank#}5{#/blank#} (teach) me never to accept pay for a kindness since my childhood, as it is pleasant enough to {#blank#}6{#/blank#} (simple) help someone!” He said, “Then I thank you from the bottom of my heart.”{#blank#}7{#/blank#} these words, he left that house, not only feeling stronger physically, but also {#blank#}8{#/blank#} (have) more faith in the human race. He was about to give up and quit before this point. It was this glass of milk {#blank#}9{#/blank#} filled him with warmth to go on. Years later, he made {#blank#}10{#/blank#} as a famous physician, but he never forgot that young woman and her kindness.

    Ski touring is exactly that—touring on skis. It combines {#blank#}1{#/blank#} best bits of skiing and mountaineering and provides the perfect way {#blank#}2{#/blank#} (explore) the mountain in winter. The {#blank#}3{#/blank#} (advantage) of ski touring are that you can really escape the crowds, enjoy the peace of the mountains and {#blank#}4{#/blank#} (reward) with breathtaking views and exciting descents.

    Ski touring involves both going up and down the mountain; both of {#blank#}5{#/blank#} (they) present challenges and new skills are to be acquired. There is much to learn about getting up the mountain that improves efficiency and saves energy. {#blank#}6{#/blank#} (similar) ，you want to be prepared to enjoy going down, which means learning to deal with the variety of snow conditions you will face. Because all ski touring is very demanding, you must be {#blank#}7{#/blank#} good physical condition. The fitter you are, the {#blank#}8{#/blank#} (much) fun you will have.

    Rapidly changing conditions and the human factors are the primary reasons for accidents. The human factors include stress, poor {#blank#}9{#/blank#} (communicate), over-confidence and tiredness. You should always ski within the limits of your ability, and make sure you know {#blank#}10{#/blank#} to navigate (导航) properly with map and compass.

    Skin is not only large, but it is important. One of its jobs is to protect us, {#blank#}1{#/blank#} keeps bad things out. But sometimes it fails. {#blank#}2{#/blank#} (extreme) small bugs, called mites, can get under our skin. And when they do, they cause itching and great discomfort. So, to get under someone's skin means to annoy them or to bug them. That's just one definition of the {#blank#}3{#/blank#} (express) "to get under someone's skin." It can also mean that someone is very {#blank#}4{#/blank#} (attract) to you. You can't stop thinking about them. You might even be obsessing （着迷）about them.

    There are many ways {#blank#}5{#/blank#} (describe) people using the word "skin." If someone is thick-skinned they are not easily hurt emotionally. You can criticize them or be unkind to them and it simply rolls off their back. Thin-skinned people, {#blank#}6{#/blank#}, are easily hurt by criticism, even if it is not too severe. You have to be careful about {#blank#}7{#/blank#} you say to thin-skinned people so as not to hurt their feelings.

    If someone is suddenly very {#blank#}8{#/blank#} (scare), you can say they nearly jumped out of their skin! For example, one day I saw my friend Sierra {#blank#}9{#/blank#} (wait) at a bus stop. She was wearing headphones and did not hear me come up behind her. So, when I {#blank#}10{#/blank#} (touch) her shoulder, she nearly jumped out of her skin!

    Fu Xuewei, a 25-year-old girl from Chengdu, China {#blank#}1{#/blank#}（recent）shared a beautiful set of wedding photos on the Internet. However, there's a debate on the photographs {#blank#}2{#/blank#} no groom（新郎）seems to be found in the photos. In fact, the only people featured in the photos are Ms. Fu and her 87-year-old grandfather.

    Despite having no plans of getting married anytime soon, Fu decided {#blank#}3{#/blank#}（wear）the wedding dress for her grandfather. The man fell seriously ill last September, with doctors warning that he could pass away{#blank#}4{#/blank#} any time. {#blank#}5{#/blank#}(fear) he might never get to fulfill the dream of walking her down to the Mr. Right, Fu arranged the surprise photo shoot. Keeping her plans a secret, she took {#blank#}6{#/blank#}（she）grandfather for a regular hospital check-up, only to reveal that they were going to take pictures later and he agreed.

    Ms. Fu {#blank#}7{#/blank#}（raise）by her grandparents from the age of ten,{#blank#}8{#/blank#} makes them mean a lot to her. She insists on taking care of them in return. The young woman even{#blank#}9{#/blank#}（have）a tattoo（纹身）of her grandfather. "I had my grandfather's appearance tattooed on my arm because I want all my new {#blank#}10{#/blank#}（friend）to know what he looks like in the future," she said.

    Every year, butterfly(蝴蝶) lovers in California go out in November to count monarch butterflies. They {#blank#}1{#/blank#}(get) a worrying result from their fall monarch count in 2018—{#blank#}2{#/blank#} number of monarchs had dropped by 86% since 2017.

The orange and black monarch butterflies are famous {#blank#}3{#/blank#} their long migrations(迁徙)—they fly thousands of miles every year. In the spring and summer they fly north; in the fall they fly south again.

    Monarchs, like most butterflies, are {#blank#}4{#/blank#}(terrible) important for plants. They help create more plants by spreading pollen(花粉) between plants. In turn, monarchs depend on plants for food. And they depend completely on a plant called milkweed {#blank#}5{#/blank#}(lay) their eggs.

    But monarchs have been facing growing problems for years. As more and more wild land has been turned into large farms, the monarchs have had trouble {#blank#}6{#/blank#}(find) enough milkweed. Many farms also use chemicals {#blank#}7{#/blank#} will kill insects in order to protect their plants. These chemicals also affect monarchs. Besides, pollution has made milkweed less {#blank#}8{#/blank#}(health) for the monarchs than it used to be.

    Scientists say monarchs will be in danger of dying out in the next 20 years if nothing {#blank#}9{#/blank#}(do) to save them.

   {#blank#}10{#/blank#}(thing) that people can do to help include planting milkweed, controlling the use of chemicals, protecting wild areas, and planting trees.
