Do you like music? Probably. But do you like all kinds of music? Want to say no? Well, before answering this q{#blank#}1{#/blank#}, you'd better have a good understanding of what music is. A music teacher wanted to tell his students the difference b{#blank#}2{#/blank#} music and noise (噪音). He brought many wooden blocks (大 块) of different sizes to class. The students were very s{#blank#}3{#/blank#} to see him throw the blocks at the wall. Everyone thought it was noise. He then took the same blocks and threw them at the wall a{#blank#}4{#/blank#}. This time, however, he threw them in a special order (次序). The students quickly found it was a tune (曲 子). "So," asked the teacher, "what is music?" The answer is that it's organized noise.

    The following are the messages from Mike's moments (朋友圈) on WeChat during the trip to Beijing.

    Today is July 5, my birthday, the first day of our trip. It's 2:30 p. m. I'm riding a bike with my parents and my little brother Bob in Beihai Park. We are singing, listening to birds, and having a lot of fun.

    Today is July 6. It's the second day of our trip. We plan to visit the Great Wall. There area lot of people along the way. I feel a little tired, but I'm happy! While we are climbing the mountain, I talk about my future (将来的) job with my parents. What do I want to be? Ha! Maybe a teacher or a singer.

    My parents are visiting their old friend, a famous writer, at her place. I am having lunch with Bob and watching a show in Deyunshe. The food isn't so delicious but the show ... Well, it's so humorous and interesting. I really like it.

    It is the fourth day of our trip. We're going back home at 6:00 p. m. It's 10:00 a m. now. We are visiting the famous Chocolate Factory and making chocolate by ourselves happily. We are really having a great time here! Sweet Kiwi! I love you!

In a small room, Jenny was lying in bed waiting for an operation (手术), nervous and worried. To her surprise, a new patient was sent into the room. After a kind greeting (打招呼), they began to talk. The 80-year-old newcomer was named Susan. She had two children. Her son was boss of a big company and her daughter worked in a TV station. As her children were too busy to take care of Susan, she lived in an old people's home. Susan was proud of her children who had wonderful jobs and made a lot of money. Jenny really envied (羡慕)Susan. Compared with Susan, Jenny was nothing but an ordinary (普通的) woman from the countryside. Her children were just ordinary workers.

Soon, it was supper time, Jenny's daughter cooked several dishes which were her favorite. Jenny invited Susan to share her supper, but she did not accept the invitation. Susan was expecting her daughter when she received a call. Unfortunately (不幸), her children couldn't come to visit her. Worse still, Susan had missed the mealtime in the hospital. She lay in bed, disappointed and silent. Jenny's daughter offered to buy her some food but she had no appetite (食欲) at all.

The next day, Jenny and Susan would go through a series of regular medical checks (一连串的常规检查) before the operation. Jenny's daughter took care of her carefully while Susan was still alone. Out of sympathy (出于同情), Jenny's daughter helped to queue up (排队), fill in different forms and register (挂号) for Susan. For several days in hospital, even during her operation, Susan's children didn't come. Susan really envied Jenny as her daughter looked after her all the time until she recovered and moved out of hospital.

Care from the loved ones can really make one happy and encouraged, especially for old parents. So don't forget to look after your parents even while you are busy working.

Do you have a friend with an interesting background? Today, I'd like to tell you about a friend of m{#blank#}1{#/blank#} with it. I'll tell you a bit about her, such as where she's from and why we're good friends.

You know, I didn't use to do s{#blank#}2{#/blank#}. However, a couple of years ago, I j{#blank#}3{#/blank#} a fitness club. There, I met Linda. After the exercise, we had coffee together and b{#blank#}4{#/blank#} good friends soon. I think we have a lot in c{#blank#}5{#/blank#} —we both like to keep fit and love trying different food. And we love the ocean; in summer, we like to play at the b{#blank#}6{#/blank#} and go swimming there. Linda was b{#blank#}7{#/blank#} in London, but has lived in China for ten years. So she can s{#blank#}8{#/blank#} both Chinese and English. That's something different about us. Another d{#blank#}9{#/blank#} is her background—Linda has experience and knowledge of two cultures.

So, now you know a bit about my friend Linda. Although we might not always live in the same city in the f{#blank#}10{#/blank#}, I think we'll stay friends forever.

Everyone knows that exercise is important. We all need to exercise. Doctors say it is good for us. It makes our heart and body strong. Children who often exercise are more clever. This means they do better in tests and schoolwork than those who don't exercise. There are many ways to exercise. 

You can walk, run, swim, skate or play ball games. Make sure you exercise in the following ways. You have to like what you're doing. Exercise enough but not too much. It's best to exercise twice each week. Thirty minutes each time is enough. Try all kinds of things until you find one, two or even three sports that are right for you. 

You can exercise at fitness centers（健身中心）. They have a lot of equipment （设备） there. The equipment will help exercise your arms, legs and other parts of your body to make you fit. Some people buy equipment for their homes. But it is very expensive. 

Exercise can be fun. Friends can exercise together at a fitness center, or they can play sports together. How do you exercise? 

Why do we go to zoos?Millions of people around the world visit zoos each year,but the reason is hard to explain.{#blank#}1{#/blank#}But the animals they see in zoos are little like the toys,cartoons,and decorations that fill their homes. For such children,meting with real animals can be confusing even upsetting

The great interest that children have in animals today might lead one to suppose that this has always been the case.{#blank#}2{#/blank#}That was also when zoos became an important part of middle-class life. 

{#blank#}3{#/blank#}They lived together with our ancestors（祖先）in a shared natural environment. In the Industrial Era,the human domination（支配）of animals could be seen in the popularity of real-looking animal toys. 

Children rode rocking-horses that had realistic features,and they slept with bears,tigers,and rabbits that looked and felt almost real. The Twentieth Century marked a further development—the change of animals into people. 

This was the age of Babar the Elephant,Hello Kitty,and the Lion King. Parents and children had previously wanted animals that looked like animals. {#blank#}4{#/blank#}

In a zoo they hope to see the living breathing versions of their character friends. They find instead unfamiliar creatures who cannot speak,smile or interact with them. For this reason,a visit to the zoo can be disappointing for children today. {#blank#}5{#/blank#}Meeting real animals reminds us forcefully of the boundary( 界 限 )between imagination and reality. When we visit animals in a zoo,perhaps we will recall our true relationship not only to animals but to the entire world. 

A. Animals are the best friends of the human beings. 

B. Many of those visitors are children,whose lives are already surrounded by animals' images. 

C. Perhaps that disappointment is the best gift a zoo can offer

D. But now they want animals that look and act like humans

E. Yet,it was not until the Industrial Era that animals became part of childhood. 

F. In prehistoric times,there had been no zoos,as animals were a real part of the human world
