During our daily life, we are often faced {#blank#}1{#/blank#} problems that simply turn out {#blank#}2{#/blank#}(be) more difficult than {#blank#}3{#/blank#}(expect), and this, in turn, causes great negative feelings. However, most difficult {#blank#}4{#/blank#}(experience) will become {#blank#}5{#/blank#}(value) lessons,{#blank#}6{#/blank#} can help us prevent future mistakes. Besides, the tough situations {#blank#}7{#/blank#}we can see ourselves differently offer us an opportunity to achieve self-promotion, and they also make {#blank#}8{#/blank#}easier for us to get through hard times in the future.

    As long as we have {#blank#}9{#/blank#}strong will, the temporary difficulties {#blank#}10{#/blank#}(overcome) and we can live through them with a better preparation for the future.

    Music is in the corners of everyday life. It is said to be beneficial to us both {#blank#}1{#/blank#}(physical) and mentally.

    There are many ways to make music. For example, if you blow into bamboos or shells, {#blank#}2{#/blank#}(permit) air to come in, they can produce pleasant music. A recent discovery suggests that music was played much earlier than we think. In 1995, deep in {#blank#}3{#/blank#} cave in Slovenia {#blank#}4{#/blank#}was occupied 45,000 years ago by Neanderthals, a leg bone of a bear with four finger holes was found. The discovery suggested that flutes（笛子）had come into {#blank#}5{#/blank#} (exist) at that time. Later, many other {#blank#}6{#/blank#}(tradition) musical instruments like drums were dug out from underground. Ancient people even {#blank#}7{#/blank#}(seek) a way to make music out of a bow that {#blank#}8{#/blank#}(intend) for hunting, so we have to admit that they did have a great gift {#blank#}9{#/blank#} music. But if exactly dated, the Neanderthal flute is by far the {#blank#}10{#/blank#}(early) known example of music.

    Now music can be found in every known culture, and even the most distant groups have a certain form of music.

    Martin Luther King, Jr. was an American leader of the civil rights movement in {#blank#}1{#/blank#} 1960s.King {#blank#}2{#/blank#} (remember) for his non-violent protests against the unequal treatment of African-Americans. His actions led to equal rights {#blank#}3{#/blank#} (law) for all people.

    In addition to {#blank#}4{#/blank#} (become) an activist, King was a scholar and religious leader. One of the most famous events related {#blank#}5{#/blank#} him came in 1963.That year, more than 250,000 people assembled in Washington, D.C. for the “March on Washington". King delivered a historic address {#blank#}6{#/blank#} (know) as the" I Have a Dream speech, one of the most famous lines from the speech {#blank#}7{#/blank#}(read): I have a dream {#blank#}8{#/blank#}one day little black boys arid black girls will be able to join hands with little white boys and white girls as sisters and brothers.

    King's actions helped pass the Civil Rights Act of 1964.The law ended the legal {#blank#}9{#/blank#}(separate)of people by race in public places. Although the Civil Rights Act was important, it did not address all kinds of {#blank#}10{#/blank#} (race)discrimination.

    Today my topic is how {#blank#}1{#/blank#} (improve) our spoken English! Before we get {#blank#}2{#/blank#} (start), I would like very much to know how important you think spoken English {#blank#}3{#/blank#}! This is the basic question we have to figure {#blank#}4{#/blank#} before we solve our problems! Obviously, English is a language, {#blank#}5{#/blank#} makes it absolutely important to speak it out! As the {#blank#}6{#/blank#} (say) goes, you learn to swim by swimming and you learn {#blank#}7{#/blank#} (drive) by driving. So, if you want your spoken English {#blank#}8{#/blank#} (improve), you have to catch every chance to speak {#blank#}9{#/blank#} (with) worrying about losing your face or making mistakes! You should always remember and tell yourself that "practice makes perfect"! With a little more confidence and hard work of practice, {#blank#}10{#/blank#} won't take you too much time to make progress in your spoken English!

    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.
