The college entrance examination is just around the corner. Homework and tests will keep many of you up late at night, and you may plan to make up for your lost sleep during the weekends. {#blank#}1{#/blank#} is it useful? A study published in the journal Current Biology completely has changed {#blank#}2{#/blank#} people used to think. It shows that the habit of sleeping in on weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}3{#/blank#} (bad), it may damage your health.

Machines work well at a constant speed —and the faster the better.Whether they are spinning cotton {#blank#}1{#/blank#}dealing with numbers,regular,repetitive actions are what they excel at.

A few years ago,I became very interested in what it meant {#blank#}7{#/blank#}(pause).I started to notice where pauses show up in my own work and life.For example,I realized when I was writing,a short walk was a(n) {#blank#}8{#/blank#}(effective)way to focus than concentrating harder.The small walk acted as a pause, {#blank#}9{#/blank#}(enable)me to rest,reflect or refresh,appreciate and break a block in my {#blank#}10{#/blank#}(creative).I realized that pause is not nothing!

A minute eating ice-cream is not the same as a minute doing push-ups.Even time itself isn't a uniform raw material —as the physics of Einstein shows.

Starting a club of some kind at school can be difficult. But with a good idea, some active friends, and the right knowledge, you can pull it off. {#blank#}1{#/blank#}.

Decide whether you really want to start a club. Once you have strong enough support from your friends and fellow students, you're ready to go.

{#blank#}2{#/blank#}. Find an advisor for your club. Pick someone who will help you organize events for your club.

Find a place. {#blank#}3{#/blank#} If you want to do this,  talk to your headteacher to apply (申请) for a classroom.

Decide when to meet. Decide how often your club should meet, and then pick a convenient time and day when most club members will be free.

Advertise your club at school. Make bright, colorful informative posters (海报) that will attract attention. {#blank#}4{#/blank#}.

Plan volunteering events. You can decide on events yourself, or hold a meeting to get your club's opinion. {#blank#}5{#/blank#}

Have fun. What's the point of having a club if it's no fun? Don't take yourself too seriously and be sure to have a sense of humor.
 

One of the interesting things about languages is the way they change over time. In English, everything from spelling to vocabulary has 1  major changes over the years. In fact, to a modern speaker, the English of 1000 years ago looks like a 2  language!

The history of English dates back around 100 years. At that time, groups of Europeans 3  England, bringing their language with them. It developed into old English. Later in 1066, English was invaded by the Normans from France. The language went through an important shift leading to what we now call Middle English. Over the next 500 years, the language underwent 4  shifts, leading to modern English. As the language has developed over time, many things about it have changed.

5 is one of the most obvious areas. For example, in old English, people say "hus" and "mus". Now, we say house and mouse. These days there are many differences in the way English is pronounced in the U.S., India and elsewhere. When people live in groups separated by great distances, the 6 of change can be fast.

Vocabulary changes happen even more quickly. English has grown by borrowing words from languages such as French, Spanish and 7 , 8 . This often happens with types of 9 -for example, "tofu". Then there is slang which enters and 10 the language every year! Thirty years ago, one often heard people saying "groovy", meaning great. These days you rarely hear the word 11 on old TV shows or movies.

Because English is spoken by so many people worldwide, it really is an exciting time for the language. Just as American and British versions are always changing, so are versions 12  in Canada, 13  and elsewhere. At the same time, an entirely new version of English is appearing on the Internet with whole new 14  and writing styles. In a way, learning English is a never-ending process, even for native speakers! The atmosphere is as much a part of the earth as 15  its soil and water of its lakes, rivers and oceans.

One teacher had two students. One of them had a positive vision while the other had the 1 one.

One day, the teacher 2 for a park with both the students and while wandering in the garden, they 3 a mango tree from which some ripe and juicy mangoes were 4 . On seeing this, the teacher thought to 5 both of his students. Then, he asked the first one, "My dear child, what do you think of this mango tree?"

The student answered instantly, "Teacher, in spite of people 6 this tree with stones, it gives us sweet and juicy mangoes. It does 7 but still it gives us fruits. I wish all human beings learn this important 8 from the mango tree-to share their 9 even if they have to suffer for this."

After that, the teacher asked the other student the same question. The student 10 answered, "Teacher, this mango tree is no good and will not give mangoes by itself but only when we hit it with stones and 11 . Therefore, we should hit it hard to get sweet mangoes from it. That is the only way to 12 these mangoes. It is also clear from this tree that in order to get good 13 from others, we need to be violent and only when we become violent, then and only then will we get 14 ."

The teacher was delighted with the answer given by the first student because he had an admirable vision and 15 the tree with positive vision.

The popularity of ancient towns in the south of the Yangtze River, such as Zhouzhuang and Wuzhen, has aroused a nationwide trend in the construction of ancient towns. Lin Peng, the director of China's Institute of Ancient Cities and Cultural Studies, pointed {#blank#}1{#/blank#} that there are more than 2,800 developed or developing ancient towns in our country, {#blank#}2{#/blank#} is definitely the highest number globally.

In ancient towns, {#blank#}3{#/blank#} immersive（沉浸式） experience being mentioned here is historical and cultural characteristics—the "ancient" of ancient towns. Apart from visible "special buildings", characteristics also include invisible "culture". Tourists in ancient towns want to see the living {#blank#}4{#/blank#} （condition） of local people, feel the vitality of town life, try characteristic local snacks {#blank#}5{#/blank#} （influence） by geography and folk customs, and understand how long history {#blank#}6{#/blank#} （shape） local culture. Out of modern fast-paced work and life, tourists want to awaken their inner softness with a slow-moving ancient town.

Touring ancient towns is for recreation, relaxation, and pleasure, {#blank#}7{#/blank#} if all the ancient towns in different places are the same and cannot find their own {#blank#}8{#/blank#} （unique）, then ancient town tourism will {#blank#}9{#/blank#} （eventual） decline. Let every ancient town become a unique historical imprint（印记）, so that tourists can find their "poetry and distance" while {#blank#}10{#/blank#} （wander） through the ancient towns. This is the soul that ancient towns need to regain.
