疑难追踪1.As a result, these endangered animals may even die out.(P25)难句解读结果，这些濒危的动物甚至可能会消亡。
die out意为“(动植物物种)灭绝;(风俗、习惯等)逐渐消失，消灭;(火)逐渐熄灭”。
例如：This kind of tiger is dying out.这种虎快要灭绝了。
Many traditional customs have died out because they are out of date.因为已经过时，许多传统风俗正逐渐消失。
The fire is dying out. You‘d better add some firewood.火快灭了，你最好添点柴火。
难点深究与die 相关的短语还有：die away(声音、光线、风等)逐渐平息，渐弱;die down(火、兴奋程度)渐弱，渐息;(光线、声音)静下来;be dying for渴望，极想;die off(家族，种族等)相继死亡，(草木)先后枯死;die of死于饥饿、寒冷、中毒、疾病、年老、忧伤、发烧、热等(内因);die from死于受伤、事故、粗心、饮酒等原因(外因)。
2.not enough food: loss of bamboo growing areas.(P25)难句解读没有足够的食物：缺少种植竹子的地方。
loss作名词。
意为“遗失，丧失;损失，损坏;输，未赢”。
其动词形式lose。
例如：Did you report the loss of your jewellery to the police?你有没有把你丢失珠宝的事报告给警方?The company suffered a heavy loss as a result of that mistake.因为那次错误，公司损失惨重。

HOW DAISY LEARNED TO HELP WILDLIFEDaisy had always longed to help endangered species of wildlife. One day she woke up and found a flying carpet by her bed. “Where do you want to go?” it asked. Daisy responded immediately. “I’d like to see some endangered wildlife,”she said. “Please take me to a distant land where I can find the animal that gave fur to make this sweater.” At once the carpet flew away and took her to Tibet. There Daisy saw an antelope looking sad. It said, “We’re being killed for the wool beneath our stomachs. Our fur is being used to make sweaters for people like you. As a result, we are now an endangered species.” At that Daisy cried, “I’m sorry I didn’t know that. I wonder what is being done to help you. Flying carpet, please show me a place where there’s some wildlife protection.”The flying carpet travelled so fast that next minute they were in Zimbabwe. Daisy turned around and found that she was being watched by an elephant. “Have you come to take my photo?” it asked. In relief Daisy burst into laughter. “Don’t laugh.”said the elephant, “We used to be an endangered species. Farmers hunted us without mercy. They said we destroyed their farms, and money from tourists only went to the large tour companies. So the government decided to help. They allowed tourists to hunt only a certain number of animals if they paid the farmers. Now the farmers are happy and our numbers are increasing. So good things are being done here to save local wildlife.”Daisy smiled. “That’s good news. It shows the importance of wildlife protection, but I’d like to help as the WWF suggests.”The carpet rose again and almost at once they were in a thick rain-forest. A monkey watched them as it rubbed itself. “What are you doing?” asked Daisy. “I’m protecting myself from mosquitoes,” it replied. “When I find a millipede insect, I rub it over my body. It contains a powerful drug which affects mosquitoes. You should pay more attention to the rain-forest where I live and appreciate how the animals live together. No rain-forest, no animals, no drugs.”Daisy was amazed. “Flying carpet, please take me home so I can tell WWF and we can begin producing this new drug. Monkey, please come and help.”The monkey agreed. The carpet flew home. As they landed, things began to disappear. Two minutes later everything had gone-the monkey, too. So Daisy was not able to make her new drug. But what an experience! She had learned so much! And there was always WWF…ANIMAL EXTINCTIONMany animals have disappeared during the long history of the earth. The most famous of these animals are dinosaurs. They lived on the earth tens of millions of years ago, long before humans came into being and their future seemed secure at that time. There were many different kinds of dinosaur and a number of them used to live in China. The eggs of twenty-five species have been found in Xixia County, Nanyang, Henan Province. Not long ago a rare new species of bird-like dinosaur was discovered in Chaoyang County, Liaoning Province. When scientists inspected the bones, they were surprised to find that these dinosaurs could not only run like the others but also climb trees. They learned this from the way the bones were joined together.Dinosaurs died out suddenly about 65 million years ago. Some scientists think it came after an unexpected incident when a huge rock from space hit the earth and put too much dust into the air. Others think the earth got too hot for the dinosaurs to live on any more. Nobody knows for sure why and how dinosaurs disappeared from the earth in such a short time.We know many other wild plants, animals, insects and birds have died out more recently. According to a UN report, some 844 animals and plants have disappeared in the last 500 years. The dodo is one of them. It lived on the Island of Mauritius and was a very friendly animal. Please listen to a story of the dodo and how it disappeared from the earth.。

Lesson 1 avatarsThe avatar you choose says a lot about you．The article will help you understand your choice of avatars better．When you are online，you can be anyone or anything. You can create your own image and a new personality．These digital identities，known as avatars，are a key part of how people use the Internet to communicate and express themselves．The first simple 2D avatars appeared in role-playing computer games in the 1980s．Yet，very few people knew that future avatars would have such a wide variety of forms and uses．By the late 1990s，they had been used in web chats like instant messenger．When people started creating their own avatars，they discovered that they were going to have the power to create new identities that did not look or act like their real selves at all．They could dress their avatars in fancy clothes，or they could try being someone of the opposite sex，and call themselves "Andy" instead of"Anna"! When Internet users realised that their avatars would be seen by many people，not just their friends，they started having more than one avatar：a sensible词one for work；a friendly，good-looking one for meeting people；and a silly one for having fun．Avatars let you express yourself and they give you lots of room for creativity.Of course，the avatar you choose says a lot about your personality．If your blog avatar is a picture of a cute cat，your message is "I like relaxing and having fun"．Well-known cartoon characters or laughing monkeys say "I'm a really funny person"．Most people create avatars that have similar features to their personalities and that look more or less like them and act like them．However，nearly all avatars are tall，young and nice-looking，so people obviously make their avatars look better than they do in real life．They also experiment with things like different hairstyles — which says a lot，perhaps，about what they want to look like．Nowadays，avatars are everywhere．In most web chats，people choose an avatar from a selection of ready-made images，or create their own images．You can also use avatars that move around and talk when you type in your message．The avatars in online worlds can talk，walk and fly around，meet people，go shopping and attend classes．The use of avatars has also caused a few concerns．Some users worry that they are spending so much time in virtual worlds that they are becoming afraid of meeting people in the real world．The use of several avatars can also be a risk，as people can use avatars to cheat others online．However，other users view avatars in a more positive light．They look forward to a time when their avatar will act like a real person and travel around bigger，more exciting virtual worlds．The Internet Harms FriendshipsWhile the Internet can bring people closer together，it can also harm friendships．Firstly, talking online is no replacement for face-to-face contact— images really cannot replace a real-life smile or hug．According to a parenting expert，Denise Daniels，communicating through a screen makes it more difficult for children to concentrate or show kindness to others．As we know，important social skills are develop ed through direct contact with other people．It is these skills that enable us to develop lifelong friendships．Secondly，the Internet can make people self-center ed — not thinking of anyone or anything but themselves．For example，instead of having proper conversations with their friends，some people are only concerned with their online popularity — How many "likes" did I get?How many followers do I have? — though we know that the number of "likes" or followers cannot compare to having long-term and rewarding friendships．In addition, a lot of the content post ed on social media is shallow or trivial．Posts about funny cat images do not necessarily help form meaningful relationships．Thirdly, online relationships may not be what they appear to be．Friendships are built on the basis of trust，and with onlinecommunication you can never be 100 percent sure that the people you are chatting to is being honest about who they are．Because of this，going online can be particularly dangerous for people who are easily influenced or too trusting．In my opinion, friends should focus more on face-to-face communication，and less on online communication. This is the best way to maintain healthy relationships．Cathy's BlogThe Internet Helps FriendshipsThe Internet can help develop friendships in many ways．Firstly，the Internet makes communication much more convenient．You can stay in touch with friends no matter where you are or what you are doing．Using a smartphone，a tablet or a computer，you can be in contact at home and also when you are on the move.Secondly, the Internet has also made communication more fun．Traditional ways of communicating，like letters and phone calls，can be limiting and take time．However，you can share photos，videos，news stories and websites with your friends online. You can give a brief response to a message with an emoji or a picture．There are so many online tools you can use to be creative!Thirdly，online communication can actually bring people closer to eachother．Nowadays，your friends are just a click away．Whenever someone needs help，friends from all over the world can immediately provide useful suggestions or information. This makes friends feel loved and cared for．To me，this is a very thought-provoking argument, as it points out the benefits of online friendships．As Eileen Kennedy-Moore，an authority on the subject，points out，online friends "fill holes real-life friends can't fill"．Finally, I believe the Internet brings people close r together and makes communication with friends more convenient and interesting．Teens Talk About Books!User name：Happy HermioneAge：17My location (optional)：Wuhan，ChinaAbout me：I'm a senior secondary school student and my favourite subject is English．I also enjoy history and geography，and I love exploring new places with my family．In my free time，I'm usually in the library or at the park with a good book．I've always loved to read! I think reading is just another way of exploring the unknown world．It's an exciting experience for me．That's why I believe that books about foreign cultures or imaginary worlds are the best!Favourite types of books：Fantasy and travelFavourite books：I like all the books in the Harry Potter series．However，I believe the first one is the best．In my opinion，the author did an amazing job of creating a whole new world through this book．After reading it，I wanted to find out what happened to each of the characters. I like Hermione most，because we have a lot in common．Are there other readers who also like her?Reason for joining the reading club：I think it's fun to hear about new books that other people enjoy．Is there a fantasy book that you really like? Let's share ideas．语法：1．构成：would／should (should 用于第一人称) + 动词原形2．用法：①表示从过去某时来看，将要发生的动作或存在的状态。
