Dear Su Nan,

I used to be like you! But don't worry, and I'd like to give you some advice on how to improve your spoken English. _____________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________________

Do you want to be an inventor? The following advice may help you.   

(one), get creative. Inventors know how to think outside the box and solve problems in different ways. How to get creative? Well, you can read as much as possible. A study shows that people who read a lot are usually (creative) than those who don't read. Doing artistic activities is also (help). For example, painting and coloring let you have a creative mind.

Second, learn STEM subjects. STEM stands for science, technology, engineering and math. These subjects are necessary if you want to be an inventor, you'll need to use the knowledge to create your projects. So take as many (course) on STEM as possible at school.

Third, join school clubs. Learning from others is important for an inventor. In school clubs, you can meet many creative people and learn from (they). What's more, there may be clubs in your school that encourage you (invent). You can join a club like the robotics club. There you'll learn a lot about science and technology. You can also try (join) something like the chess club. It encourages your logical (逻辑的) thinking.

Fourth, practice hobbies as much as you can. Imagination plays important role in making you an inventor and hobbies can feed your imagination. Having a lot of hobbies (allow) (允许) you to develop the innovative (创新的) mind of an inventor. Making cakes is a great example.

According to a report, human activities have caused the world's wildlife populations to fall by about two-thirds in the last 50 years. Scientists predict that about 90% of wild animals will lose some of their habitat (栖息地) — for example, forests — by 2050.

One company came up with an unusual idea: saving wild animals by making apps.

It looks like the animal is really there in your photo, but of course it isn't! Another app challenges you to run farther than a real lion or a tiger. You can read stories about what the animal is doing and where it is going. There's also a game that shows you some of the things scientists are doing to save wildlife. You can look at hundreds of wildlife photos that real scientists took there and learn about the scientists' work.

Gautam Shah, who started the company, believes that we will only be able to save our planet's animals if enough people want to make big changes.     

So many people around the world play games on their smartphones. If all these people are also interested in wildlife, maybe they can change the world.

A. But the wildlife populations will increase in the future.

B. And things will get worse unless we make big changes.

C. He wants to make more people interested in wildlife through his company's fun apps.

D. One of the company's apps lets you take a photo with a bear, an elephant or other animals.

E. In this game you are a scientist finding out about wild animals in forests in Southeast Asia.

F. Many people around the world are trying to find ways to save wild animals before it is too late.

The deserts are not as dry as they look. They have groundwater. A new study   says this could help explain the mystery. Lucas Goehring, an expert in physics at Nottingham Trent University in England, led the study. He and his team came up with an explanation for the six-sided shapes.

According to Goehring, below the desert surface is a layer (层) of salty water. You can reach it by digging with your hands. In the hot summer months, the water evaporates (蒸发). This leaves only salt behind. Some of the salt goes into the next layer of water. This layer of water then becomes thicker and saltier than the   one below it. The saltier water goes down and the fresher water goes up.

The process repeats itself to form what scientists call a convection roll (对流圈) which normally has a round shape. There are so many of the convection rolls and they press against each other to form the six-sided shapes.

Scientists say they did their work out of curiosity (好奇心). "Nature presents us with a fascinating mystery," said Jana Lasser, another expert who helped with the study. "It makes us want to solve it."

Could we make a real-life Baymax? There have already been most of the pieces needed to create it. But putting them all together is another story. "There're all kinds of things that need to come together to make something as amazing as Baymax," says Alex Alspach, a robot expert at Toyota Research Institute in the USA.

To build a real-life Baymax, experts need to think about many things. They need the right hardware to make up the robot and the right software to control its movements. They need to plan what the robot looks like and make sure it's safe for humans.

The real-life Baymax needs to be light. If he is too heavy, he might hurt his patients. That is why he should be soft on the outside and full of air inside. But keeping Baymax filled with air would be difficult as he would need to carry a lot of hardware. Heat is also a problem. The motors that make Baymax work will make lots of it. That's dangerous.

The robot's walk is another challenge. He should be able to move around small spaces. "I don't know of anybody who can make a robot move like that right now," says Cindy Bethel, an expert at Mississippi State University.

The real-life Baymax will also need lots of sensors . Scientists are working on sensors that can tell if a person is sick.

Most experts agree that big steps towards making the new robot will come soon. "I think kids will get to see that in their lifetime," Alspach says.

We started by looking at some old paintings in a big room. My mom explained that they were created by famous artists a long time ago. And that's when the trip started to get interesting for me.

Next, we went to a room with real dinosaur bones (骨头). They were huge, and I couldn't believe that animals that big ever existed (存在). We learned how they lived and looked for food. It was cool!

Then, we entered a room with old handcrafts . There were bowls, musical instruments, and even a pyramid (金字塔)! I couldn't believe they were made so long ago—without modern machines. It was amazing to see how people used to live back then.

Lastly, we visited a room with real live insects and animals. There were butterflies flying all around and even a big spider! I got a little scared, but my mom told me they were behind glass and couldn't hurt me.

After we saw everything, we went to the gift shop. I got a cool ruler with dinosaur facts on it and a little toy dinosaur. My sister got a book about space, and my dad got a cool T-shirt.

Going to the museum was fun! I learned so much about history, science, and art. Guess what? I'm taking back everything I said about museums—and I can't wait to go back and see what else is there!
