At each stage of our life，we meet different kinds of people. Some are funny； some teach us lessons in life while others occupy a special space in our heart. The people {#blank#}1{#/blank#} (call)"best friends" are just these special friends.

    In our childhood，"best friends" might have meant the persons who are always by our side，{#blank#}2{#/blank#}it may be in the classroom or in the dining hall. However，as we are getting{#blank#}3{#/blank#} (old) than before，our definition(定义)of "best friends" changes. In my opinion，best friends are those who love you {#blank#}4{#/blank#}who you are and help you become who you should be. People in our life come and go，but some people stay. They are the people we should never lose.

    True friends are those who will never leave you when you need them most. They are always there{#blank#}5{#/blank#}(wait)for you and they love you when you forget to love{#blank#}6{#/blank#}(you)．The best feeling in the whole world is knowing that there is {#blank#}7{#/blank#}person who always prays for us and always keeps us in their thoughts. Friendship may not{#blank#}8{#/blank#}(necessary)be based on age，but it is based on{#blank#}9{#/blank#}(understand). Even our parents can be our best friends！So let us build our friendship and try our best {#blank#}10{#/blank#} (see)the good side of everyone!

    A few months ago I left my hometown for Canada to study. I felt nervous because I was going to {#blank#}1{#/blank#}new place with new people. What worried my at first was that I couldn't speak English {#blank#}2{#/blank#}(fluent), and I also couldn't understand{#blank#}3{#/blank#}(they) customs. Everything was different {#blank#}4{#/blank#}my own country. I had to deal with everything alone.

    It was a sad moment {#blank#}5{#/blank#} I had to say goodbye to my family and friends at the airport. Suddenly, I felt unwilling {#blank#}6{#/blank#}(leave) my hometown because I grew up there and had wonderful{#blank#}7{#/blank#} (memory) of the familiar place. However, I know studying abroad was a {#blank#}8{#/blank#}(decide) that I made myself. I had to accept the challenge.

    By now I{#blank#}9{#/blank#}(get)used to the new life here already, though I'm looking forward to{#blank#}10{#/blank#}(spend) the coming vacation with my old friends back home.

I'm a single mother with a{#blank#}1{#/blank#}( grow ) son. I love him more than I can say. He's a good person, a great guy {#blank#}2{#/blank#}so many ways —- smart, {#blank#}3{#/blank#}(create), kind to animals, etc. We get along well, have common interests and enjoy each {#blank#}4{#/blank#}(other) company. The rest of my immediate family is {#blank#}5{#/blank#} (die), and he is literally all the family I have.

The problem is that he is {#blank#}6{#/blank#}( turn ) 30 and shows no signs of wanting to leave home. He {#blank#}7{#/blank#}(do)move out and try the roommate route twice, but both times it did not turn out well and he moved back in with me. This wouldn't be so bad —- we do get along well —- but he doesn't pay half the expenses, or even a quarter. In fact, he doesn't pay me {#blank#}8{#/blank#} (something) at all. My frequent requests for him {#blank#}9{#/blank#}(contribute) to the rent and utilities(公用设施) often result in losing his temper and yelling at me that all I care about is money. He {#blank#}10{#/blank#} (spend) his salary on himself: clothes, movies, computer accessories. It's as if he still sees himself as a teenager with an allowance.

    If you enjoy kayaking (皮划艇运动), you can paddle for free in Denmanrk, Ireland, Germany, Sweden and Norway, but you also have to be willing to pick up trash.

    Organized by Greenkayak, free trips in the group's two-person kayaks are offered in return {#blank#}1{#/blank#}collecting waste from water surface. {#blank#}2{#/blank#}project began in Demark in April, 2017. With the help of a thousand kayak {#blank#}3{#/blank#}(voluntary), three tons of trash were collected from Copenhagen harbor that year. You can easily book a kayak for the time {#blank#}4{#/blank#}works for you. Life jackets and equipment — like a paddle, a waste picker, a bucket for the trash —{#blank#}5{#/blank#} (provide): just bring yourself. You can have two hours of free kayak time.

    Greenkayak believes that kayaks are highly effective at collecting waste because they can get close to areas that are otherwise hard {#blank#}6{#/blank#}(reach).

    "In Denmark, people love to hang out on canals, but {#blank#}7{#/blank#}(fortunate) they see waste {#blank#}8{#/blank#} (float) by." one of Greenkayak's co-founders speaks of the program's origin. "You can't take your shirt off and jump in. {#blank#}9{#/blank#} you can get in a Greenkayak and make a difference."

    If you want to take advantage of the free kayak, {#blank#}10{#/blank#}(tourist) a city from its river and do your part to control water pollution.

Emperor penguins (企鹅) are{#blank#}1{#/blank#}(large) penguins on Earth. Each adult is over a meter tall and weighs up to 40 kilos. Every year in May, mother penguins lay eggs on the coast. Then they will go back to the ocean{#blank#}2{#/blank#}(find) food while the father penguins stay and look after the eggs for the next two months. During this time, {#blank#}3{#/blank#}eating any food, a father penguin can lose half of his body weight. By August, the mothers return just in time to see their babies come out of eggs.

Human history begins with stories. Some stories are so important that they{#blank#}1{#/blank#}(pass) down for countless generations. And storytelling is a useful tool, {#blank#}2{#/blank#}gives a lesson much more powerfully than other ways. For example, once I had to tell actors to be on time for a performance. Instead of{#blank#}3{#/blank#}(repeat) the time over and over again, I told them a true story. "The year before, one of the actors was late. We replaced him so he didn't get a chance to perform." Then, no one{#blank#}4{#/blank#}(be) late again.
