Deserts are found where there is little rainfall or where rain for a whole year falls in only a few weeks' time. Ten inches of rain may be enough for many plants to survive (存活) if the rain is spread throughout the year, If it falls within one or two months and the rest of the year is dry, those plants may die and a desert may form.

    Sand begins as tiny pieces of rock that get smaller and smaller as wind and weather wear them down. Sand dunes (沙丘) are formed as winds move the sand across the desert. Bit by bit, the dunes grow over the years, always moving with the winds and changing the shape. Most of them are only a few feet tall, but they can grow to be several hundred feet high.

    There is, however, much more to a desert than sand. In the deserts of the southwestern United States, cliffs (悬崖) and deep valleys were formed from thick mud that once lay beneath (在……之下) a sea more than millions of years ago. Over the centuries, the water dried up. Wind, sand, rain, heat and cold all wore away at the remaining rocks. The faces of the desert mountains are always changing--very, very slowly--as these forces of nature continue to work on the rock.

    Most deserts have a surprising variety of life. There are plants, animals and insects that have adapted (适应) to life in the desert. During the heat of the day a visitor may see very few signs of living things, but as the air begins to cool in the evening, the desert comes to life. As the sun begins to rise again in the sky, the desert once again becomes quiet and lonely.

Lake Street School Big Day Out!

Dear Parents,

    We are happy to have our summer trip to the Children Movie Museum and the Sports Park on Thursday, July 11th (Grade Seven) and Friday, July 12th (Grade Eight). Students can learn lots of very interesting things about the cinema and how movies are made. They will also learn about many sports and their rules.

Meeting Time: 7:40 am

Leaving Time: 8:00 am

Meeting Place: at the school gate

Arriving Time: by 5:00 pm

    We have this trip for the students to learn outside the classroom and also have a good time with friends. Students need to take a pen and a notebook with them because they have to take notes about what they see. They also need to wear their school uniforms and sports shoes. Please tell them to follow the rules in the museum and the park.

    We will be eating lunch at the dining hall of the park. The cost of the trip is 40 yuan. It is for the bus ride and the lunch.

    If your child cannot come, please tell your head teacher by July 8th in your class teacher-parent WeChat group.

For most students, stress (压力) is a fact of life. {#blank#}1{#/blank#} Instead, we should find ways to have a healthy life. Here is some advice. 

{#blank#}2{#/blank#}

Sometimes it can be difficult to say exactly what we're feeling. When we feel nervous or down, it can be useful to put our problems into words. For some of us, keeping a diary is a good way to relax. 

Breathe (呼吸) deeply and do some exercise. 

Breathing deeply will help us keep coal. Then doing some exercise can make a big difference to both physical and mental (精神上的) health. {#blank#}3{#/blank#}

Sit back and listen to the favorite music. 

Music has a wonderful influence on our feelings. When we feel sad, it fills our bears with warmth and comfort. {#blank#}4{#/blank#}When we grow nervous, it helps lower our stress. 

Don't take every trouble too seriously. 

Taking everything on shoulders and treating everything that goes badly as mistakes is a one-way ticket to having the bad feelings. {#blank#}5{#/blank#}

A. When we get angry, music keeps our minds clear

B. So, it's not a good idea to run away from it

C. Take it easy and it's believed that everything can be solved

D. It's difficult for us to do enough exercise.

E. Write down what makes us worried.

F. Keeping exercising at a certain time really helps us relax.

Doing chores is important for students and we learn a lot from it. According to a survey from our school,

……

Many people think that being healthy is expensive. Well, it is not. We can be fit by simply changing our habits. {#blank#}1{#/blank#} Healthy people have healthy habits that are simple and don't require too much money. Cheøk out what healthy people do to keep their body and health in the right shape. 

 Eat breakfast.It's important for many reasons. {#blank#}2{#/blank#} What's more, different studies show that kids who have healthy breakfast score higher on test and adults who have a morning meal perform better at work. 

 Drink plenty of water.Just like breakfast, drinking plenty of water can do wonders in our body. It is not only healthy for you, but also helps you lose a few pounds. {#blank#}3{#/blank#} If you' re not a fan of plain water, you can add a slice of watermelon, lime, lemon or orange. 

 Take an exercise break.There are different ways to exercise. Light exercise can be done by jogging or walking every morning or late afternoon at least five times a week. {#blank#}4{#/blank#} Exercise is good for both the body and mind. It is also a way of relaxation. 

{#blank#}5{#/blank#} If you smoke, quit. Smoking, as we always hear it, is dangerous to your health. Quit smoking, and you' ll see a big difference in your body. It is also an important move toward better health. Your body will repair itself quickly and as soon as twenty minutes after you last light up, your blood pressure drop. So, kick that habit as early as now. 

School was out, and the Johnson family were getting ready to take their summer trip to Lake Horizon. Betsy and her brother Bruce were excited, but their parents were not.

"I wonder why Mom and Dad are not excited," Betsy said to Bruce. "I heard them talking last night. They said repairing (修补) the old cabin (小木屋) would need much money." said Bruce.

The next day, Bruce got up early. He said to Betsy, "It's time for us to do things for them. We can help paint the cabin. Then it won't look so bad, and we can save some money." Betsy thought it was great and they told their parents about the plan. "____" said Dad. "We can plant some flowers, too," said Mom.

That night, they bought some things they would need. The next morning, they left for the cabin early and arrived there before lunch. They painted the small kitchen first, then the bedrooms, and finally the living room. Then they planted some flowers in front of the cabin. Finally, the cabin looked so much better because of their two days' hard work.

Our parents always love us, do things for us but never complain (抱怨). When the time comes for us to help our parents, try our best.
