The kangaroo is the world's largest living marsupial (有袋动物). It was first found on the island of southwestern Australia. The animal was given its name by a famous English tourist in the 18th century.

    The kangaroo may be 7 feet(2.1m) tall when standing upright and the male can weigh as heavy as 200 pounds(90kg). The female (雌性) is smaller and lighter than the male. The kangaroo's head is small, but its ears are large, and its fore feet are really small. The animal has strong back legs and long tail.

    The kangaroo usually covers from 5 to 10 feet(1.5 to 3m) with each jump. The female is usually faster than the male. The mother kangaroo has a pouch (育儿袋) in its abdomen (腹部). The baby kangaroo grows up in the mother's pouch slowly.

    The kangaroo lives on grass and other plants. It is always moving from one place to another, lying down to sleep on the ground during the night. It likes to enjoy the warm sunshine. When it's in danger, it can use its back legs and strong tail to protect itself.

    If your pen broke at school today, what would you do? You would go to a shop and buy a new one. What if you could simply print out a real, working pen with your 3-D printer without leaving your room?

    Ten years ago people could only see 3-D printing in science fiction movies. But now 3-D printing is here and it's bringing big changes.

    Unlike normal printing that can only copy a 2-D picture with ink. 3-D printing can build almost anything made from material. The printer layers(分层) the material in different shapes to create the object you want to be copied.

    The 3-D printer has been used to make many different things. People have made cups, cars and even an airplane with it. Doctors have been using 3-D printers for several years. People's nervous systems(系统) have been printed out in 3-D form in medical research. Some body parts have been printed and used in hospital. Several months ago, doctors used a 3-D printer to rebuild the face of a person who had a bad accident. In the future, it is expected that the printer will make human organs(器官)to save more lives.

    However there are drawbacks to the printer. At the moment, printing can be quite slow and it's still rather expensive. The average(平均的) price of a household printer is around $1,700, not including the cost of the materials.

    But as the technology develops, it shouldn't be long before disadvantages are improved. Only time will tell where this new technology will take us.

Have you ever been at a store and then suddenly noticed some candies? You weren't {#blank#}1{#/blank#}(愿意的) to buy the candies before, but you decided to get them anyway. As a{#blank#}2{#/blank#}(结果), you {#blank#}3{#/blank#}(可能) {#blank#}4{#/blank#}(后悔) your {#blank#}5{#/blank#}(快速的) buying. This is called an impulse purchase(冲动购买). You may not {#blank#}6{#/blank#}(意识到) that it happens millions of times per day but it is {#blank#}7{#/blank#}(相当) common. Stores {#blank#}8{#/blank#}(经常) set up like this so that {#blank#}9{#/blank#}(人们) will be encouraged to pick and buy things on impulse every time they walk in the door. It is {#blank#}10{#/blank#}(真正地) a useful way for stores to increase sales.

An impulse purchase is the act of {#blank#}11{#/blank#}(支付) for some {#blank#}12{#/blank#}(产品) you don't originally(起初) {#blank#}13{#/blank#}(打算) to get before going to the store. Did you ever wonder why candies are always {#blank#}14{#/blank#}(提供) in the lower {#blank#}15{#/blank#}(地方) on shelves? {#blank#}16{#/blank#}(一旦) kids are tall enough to see the candy down there, they are likely to beg their {#blank#}17{#/blank#}(父母) to buy it on impulse. What about a fridge full of cold drinks as soon as you walk in a convenience store on a hot day? This is also a trick with the{#blank#}18{#/blank#}(目的) of bringing about impulse purchasing. Signs, {#blank#}19{#/blank#}(图片) and packages are also {#blank#}20{#/blank#}(完美的) things to encourage impulse buying. If you see your favorite anime(动漫) character on something, you will have one more {#blank#}21{#/blank#}(理由) to buy it instead of {#blank#}22{#/blank#}(拒绝) it. This is another way to lead people to {#blank#}23{#/blank#}(准备) for impulse purchases.

The next time you enter a store, {#blank#}24{#/blank#}(记得) to look around and see how many things there are promoting(促进) impulse buying, and you will be shocked. Even so, it's  {#blank#}25{#/blank#}(可能的) for you to still end up buying something you don't want. It is difficult to change.

Hong Kong has about forty public(公共的) beaches. Some of the beaches are among the best in the world. People ` can go there for aI swim. You can go to most of them by bus. To go to some beaches, you must take a boat. There are toilets, changing rooms and places to buy food and drinks on most of the beaches.

Here are some suggestions to keep safe in the water:

Never swim alone.

Never swim after a meal or when you feel hungry or tired.

Don't stay in the water too long.

Never go out in a boat if you can't swim.

Remember: A red flag means that it is dangerous for anybody. Everybody shouldn't go into the water. A blue flag means that it is dangerous for children.

There are many ways for you to improve your English outside the classroom. Here is some {#blank#}1{#/blank#}. 

◆ Get an English pen friend. This is a great way to practise your English!

◆ You can learn English from {#blank#}2{#/blank#} or newspapers. Read a story in Chinese first, and then read it in English to see how well you can  {#blank#}3{#/blank#}. 

◆ Buy or borrow a book that is suitable (适合的) for you. The stories are interesting and the language isn't too difficult. And you can start to enjoy reading English.

◆ It's a good idea to listen to songs by one of your favourite English bands (乐队). You needn't get every word {#blank#}4{#/blank#}. 

◆ You can try an English- learning website 网站). There are many websites dedicated to (致力于) English learning with a lot of interesting information. 

◆ Don't {#blank#}5{#/blank#} to watch TV or films in English. CCTV-9 is a good choice for you. It's also a fun way to practise your listening. 

 Visiting museums can be interesting but tiring. You may spend hours getting there, waiting in a long line for a ticket, and walking with big crowds in the museum. But new kinds of technologies are changing museums and the way people visit them all over the world.

 Thanks to the Google Art Project, you may"walk through" museums while staying at home and enjoying an icy milk shake. It uses Google's Street View technology. You can see how paintings are hung and exhibits(陈列品) are placed as you move virtually (虚拟地) through the museums. You can also read the introductions of the works and download(下载) clear pictures of them. So far 560 museums around the world have joined the project, such as the British Museum in London and the Metropolitan Museum of Art in New York City.

 Some apps may also make your museum trips more fun. The Palace Museum designed a few apps. One is called Han Xizai's Night Feast. Users can see a big picture of Han's house and take a closer look at the people and the clothes within it by touching the screen. The Museum of Modern Art in New York City also made an app that allows users to draw their own modern art works.

 However, if you still want to visit museums in person, you probably won't be disappointed. Many museums are trying to allow visitors to interact(互动) with the exhibits using 3-D technology. The exhibition in Shenzhen shows a 3-D copy of ancient Chinese bronze chimes(青铜编钟). Visitors can"play" the chimes by simply touching them.

 With new technologies like this, visiting museums has become easier and more fun. So why not try it yourself?
