It is interesting to visit another country, but there are some problems when we don't know the1very well. It may be difficult to talk with the people there. We may not know how to use the telephone in the country we are visiting. We may not know how to buy the things we need. In a2country we might not know where to eat or what to order in a3. It is not easy to decide how4to tip waiters or taxi drivers. When we need help, we might not know how to ask for help. It is not pleasant to have an experience5that. After a short time, however, we learn what to do and what to6, We learn to enjoy life in another country, and then we may be sorry to leave.

    The world is in danger. At one time there were 1,300 different plants, trees and flowers in Holland, but now only 860 remain(剩余). The others have been destroyed(破坏) by man. We are changing the earth, the air, the water and everything that grows and lives. We can't live without these things. If we continue doing like this, we will destroy ourselves.

    What will happen in the future? Perhaps it is more important to ask "What must we do now?" The people who will be living in the world of tomorrow are the young of today. A lot of them know that conservation(对自然环境的保护) is necessary. Many are helping to save our world. They plant trees and protect animals in forest. In a small town in the United States, a large group of volunteers cleaned the banks of their rivers. Young people may hear about conservation through a record called No One's Going to Change Our World. It was made by the Beatles, Cliff Richard and other singers. The money from it will help to protect wild animals.

    When you're closing your eyes and hitting your pillow, you're probably not giving much thought about the sleeping position throughout the night. Most people don't change their sleeping positions throughout their lives. The following is why you might want to pay more attention: Your sleeping position can actually say a bit about who you are and what your personality is like.

    There are many sleeping positions. The fetal (胎儿的) sleeping position is generally the most common sleeping position. Fetal sleepers sleep on their side, they move into a position in which their body makes a rounded shape. People who sleep in the fetal position are often quite sensitive and generally shy. They are often worried or nervous and don't focus their attention on the main problem, but get into trouble on very small pieces of information.

    The log (木头) sleeper rests on the side with a straight body when hands and legs are kept at the sides. These sleepers are often relaxed, but also can easily believe lie-tellers. If you're a log sleeper, you might want to keep in mind that it's good to be easy-going and have less stress, but don't be so quick to go with the flow (流) at all times.

    The third one is the soldier position. Soldier sleepers typically lie on their backs with both arms close to their sides. In general, they are the strong and silent type. However, they can also put the pressure on. "They can be quite strict with themselves as well as others," a scientist added.

Hi, my name is Alice. Nice {#blank#}1{#/blank#} (meet) you! Here {#blank#}2{#/blank#} (be) two nice photos of my family. My grandparents are in the {#blank#}3{#/blank#} (one) photo. And you can {#blank#}4{#/blank#} (see) my parents in it. My father is {#blank#}5{#/blank#} English teacher in a middle school, and my mother is a teacher, too. {#blank#}6{#/blank#} are in the next photo? They are my {#blank#}7{#/blank#} (sister), Cindy and Amy. This {#blank#}8{#/blank#} (be) my brother. His nameˈs Eric. 

Do you know{#blank#}9{#/blank#} (this) two boys? Oh, they are {#blank#}10{#/blank#} (I) cousins, Bob and David. I love my family very much

Many social media posts(社交媒体帖子) may let you believe that everyone is happy all the time, but being happy all the time is not possible.

As a teenager, you probably expected to get good grades in an exam or to win the most important basketball game, but it didn't happen. Good results make you happy and bad results make you sad. But sadness can drive you to improve yourself next time.

However, when people get into sadness for a long time and it starts to affect(影响) their lives, it's called depression (抑郁). You don't want to get out of bed. You don't feel like studýing or going out with your friends. I remember the same feeling when my dog Rebel died in an accident. I remember that he followed me to school. Now he was gone, and I lost all interests to do anything.

My parents told me dogs don't live forever. What was more, Rebel had a good life. If Ihad a good life, Rebel must be happy, too.

Depression is not a person's mistake. It's normal to feel sad sometimes. Many great people, like the comedy actor Jim Carrey, once get depressed. But you should know what to do to stop depression or make yourself less depressed.

When you feel down, you must not keep yourself away from the world. Try to share your feelings with a family member or a good friend. Staying at home by yourself will make you more lonely. You should stand up, open the window, and throw away (抛弃) the sadness.
