As we know, Meizhou Island is a famous place of interest in Putian. My pen pal from Australia, Sam, would like to visit it very much. He is coming here for a holiday next week. He is planning to stay here for seven days. He has never come to Putian before, so he needs to know something about it. The weather is the most important thing that he would like to know. He wants to know what he should get ready for the trip and what kinds of clothes he has to take with him. Here is the seven-day weather report for Putian.

You've heard of 3D printing from newspaper and TV programs．It can “print”in plastic，metal，nylon，and over a hundred other materials.3D printing technology has been around since the 1980s，it was not widely used until the early 2010s．The first working 3D printer was created in 1984 by Chuck Hull．

3D printers use many different types of technologies，but they all share one thing in common：they create a three—dimensional(维度的)object by building it layer(层)，by continuing layer, until the whole object is completed．Imagine a baker(面包师)lay down each layer one at a time until the whole cake is formed.3D printing is somewhat similar， but just a bit stricter．How can 3D printers work so well? The most important thing a program，a 3D printer also needs to have instructions for what to print from a computer．It needs a file as well．The file which is a Computer Aided Design (CAD)paper is created with the use of a 3D modeling program．The program creates a paper that is sent to the 3D printer. Along the way，software pieces the design into hundreds，or more likely thousands of layers．The 3D printer builds up one layer at a time，from the bottom to the top，until the object is done．

    3D printings can be used for making many kinds of things such as machine parts， daily life objects，even human organs(器官)using a person's own cells．

Nowadays, Marc．Dillon founds a project which deals with many world famous paintings like Leonardo da Vinci's Mona Lisa, Van Gogh's Sunflower with 3D technology．This project helps the blind people enjoy the fantastic art through touching．In order to provide a good user experience，these 3D paintings have special instruments which can tell people what they touch．

    Over 80G of the ancient forests have already been destroyed. Thousand-year-old trees are cut down just to make everyday goods. More and more wild animals are in danger now. Wild animals are our friends, and we cannot live without them. If we take no action, more and more wild animals will disappear in the future. It is time for us to save and protect endangered animals. Then what can we do? Here are some steps.

    Step one: Find out what animals are living near your place. Spend some time learning about the animals.

    Step two: Help to build more nature reserves and other wilderness areas. Protecting the living areas of wild animals is one of the best ways to help protect endangered animals. You can raise money for them or spend some time helping build nature reserves.

    Step three: Buy foods and goods that are made from materials which do not harm endangered animals or their living areas.

    Step tour: Join a local Wild Animals Club. You can take action to protect wild animals. There are many global groups that try to call on people to protect the environment by changing people's ideas and behaviours. Children, teenagers, teachers and schools from all over the world can help to save the animals. Everyone can do a little to help them, and every little bit of help is important!

    Art, as we know, is subjective. What one person considers a priceless masterpiece others might see as nothing more than a giant black square. But there's one very specific kind of painting that almost everyone sees the same way-the kind with the" "strange" eyes that seem to follow you around the room. So what causes this optical illusion (视觉错觉) and how do artists achieve this effect?

    It turns out, for even a moderately skilled artist, this effect isn't a difficult thing to achieve, In fact, the artists need to use a little illusion of depth, making the person depicted on the canvas appears somewhat 3D on a 2D canvas, and to adjust .the gaze (凝视) of the eyes so that they would be looking at someone standing right in front of the picture.

    So what exactly is going on here in our brains that then makes it seem like the eyes follow you even if you move away from being front and center? As demonstrated by a team of researchers from Ohio State University, as you move to the side, the "near? and "far" points of the 2D image don't really change. These near and far points are defined as visible points that, if the image was 3D, would appear nearest and furthest away from the viewer at a given angle.

    The idea is simple. No matter what angle you look at a paining from, the painting itself doesn't change. You're looking at a flat surface. The key is that the near points and far points of the picture remained the same no matter the angle the picture was viewed from. When observing real surfaces in the natural environment the near and far points vary when we change viewing direction. When we observe a picture on the wall, the visual information that defines near and far points is unaffected by viewing direction. Still, we willingly accept and interpret the thing in the painting as if it were a real object.

    Thus, because the perspective, shadows, and light on the painting don't change as you move around, if the eyes in the painting would be staring directly at the observer who is standing in front of the painting, it creates something of an optical illusion in your brain so that the eyes will continue to seem to stare at you as you move to the side.

    In contrast to the eyes following you trick, if the artist tweaks the painting a bit, for example the artist adjusts the gaze of the eyes so that the eyes are looking off somewhere else instead of directly looking at a potential observer, no matter where you stand, the eyes will never seem to be looking at you.

    The technique first began popularly showing up in art around the 14th century when the artist and architect Fillipo Brunelleshi introduced the art world to the idea of "linear perspective", being painting with the idea of everything in the picture converging (聚集) on a specific point on the horizon, creating the illusion of depth. Linear perspective, combined with skilled use of light and shadow, allows artists to create masterfully realistic paintings, including sometimes of people that stare at you creepily no matter where you stand.

Dear Mary, 

How are you? I'm happy to be your friend. My name is Jim Smith. I'm in China now. I have a 1 . He is my aunt's son. His name is Peter Miller. He is a tidy boy, and his room is 2 , too. 

This is a photo of his room. Some books are in the bookcase. His clock and tape player are on the table. His schoolbag is on the 3 . His pencil box is on the desk, too. His schoolbag is green. What 4 is his pencil box? Oh, it's yellow. Some pens are in the pencil box. A set of keys 5 in it, too. 6 is under the desk? Oh, it's a baseball, 7 it's not his. It's his brother Alan's. Peter has a computer. It's 8 the table. On the wall, there is a photo of his 9 . There are four people in his family. 

This is my cousin's room. What about 10 ? Is your room tidy, too?

Yours,
