Robots seem very new to some people,     1     in fact they have a long history. A Greek inventor made the first robot. You may often see robots in lots of movies. The robots in movies are stronger, faster and cleverer     2     people. In real life, people use most robots in factories. They use robots to do many dangerous, difficult or boring jobs. Some people need to be looked after and robots are able     3     help them.     4     example, some people can’t see anything. Dogs can help them move around. These dogs are called guide dogs. Scientists are making robots to help them. In the future, there     5     be robot dogs that might take the place of these guide dogs.

【推荐2】The human brain's power could compete with any machine. And now a group of scientists from across Europe are trying to build one using the world's most p    1     computer.

Our brains have 100 billion neurons Each one performs billions of ‘calculations’ second   s    2     to a desktop computer.

So the brain computer will need to be able to do a billion calculations.

Finding a way to power the supercomputer will be one of the Scientists' major challenges. They hope to c    3     it within 12 years.

Group leader, Professor Henry Markram, said, “The billions of interconnected neurons make it hard for us to truly understand how the brain works. Simulating it will make it much e    4     allowing us to operate and measure any aspect of the brain.”

The brain will be built in facility in Germany. It will have thousands of 3D images, so scientists can “fly” around different areas and w    5     how they communicate with each other.

If the “brain” works, it will help scientists understand brain diseases such as Parkinson's, and know more about how we think and make d    6    .

There are concerns about the consequences of the computers which can think for themselves. But Professor Markram said “This is one of the t    7     great challengers for humans. We need to understand earth, space and the brain. We need to understand what makes us human.”

When we watch movies about the future, we sometimes see robots. They are usually like human servants. They help     1     the housework and do jobs like working in dirty or     2     (danger) places.

Today there are already robots     3     (work) in factories. Some can help to build cars, and they do simple jobs over and over again.     4     (few) people will do such jobs in the future because they are boring, but robots will never get     5     (boring) .

Nowadays there are already robots     2     in factories. Some help build cars, and they do simple     3     over and over again. Scientists are now trying to make robots look like humans and do     4     same as we do. Some robots in Japan can walk and dance.     5     , some scientists believe that although we can make robots move like people, it will be difficult to make them really think like a human. Some scientists     6     that there will be more robots in the future. These new robots will have many     7     shapes. In India, for example, scientists made robots that look like snakes.     8     buildings fall down with people inside, these snake robots can help look for people     9     the buildings. This was not possible 20 years ago, but computers and rockets also seemed impossible     10     of years ago. We never know what will happen in the future!

Last Saturday morning, the teacher called a meeting of parents. Mike     1     (make) a speech in the meeting. His mom felt happy.

Now his middle school life comes to an end. This summer, he will go to the U.S. and stay for one year to study at an American high school. There he     2     (be) in Grade 10. He feels excited. At the same time, He is a little sad     3     he has to say goodbye to his old friends and teachers. He wants to take some     4     (photo) with them. They will connect with each other by making phone calls or     5     (write) letters.

In the past three years, he has learned a lot     6     his teachers and had a great time at school. They’ll set out on their new journey, but he will never forget where he comes from. In the future, he will work much harder. He hopes to be     7     artist when he grows up. I think his dream will come true.

Nowadays Wechat is more and more popular. I often talk to my English friends on Wechat to help me speak English better than before. And I can read lots of     1     (information) on Wechat that can make me know more around. Some news also makes me become more careful. Sometimes I feel Wechat is like     2     mirror that helps me see something     3     (clear). But now, Wechat brings me some trouble as well. Some friends put photos of the real things on Wechat to tell     4     they sell is really good. I am angry about     5     (that) advertisements. Because some of them may be not true. As a     6     (say) goes, “Seeing is believing.” (眼见为实) I know people are     7     (cheat) by some news easily. What’s     8     (bad), some news always asks us to send it to others. This makes me not comfortable! Friends seem to become enemies! In fact, I am thinking about never     9     (use) Wechat on my phone again because using it too much is bad     10     my eyes.

Years ago, if a teenager had some problems in their life, they would write t    1     in a diary. Now a teenager might go online and write their daily life and     2     (feel) in a blog. In many ways, a diary and a blog are almost the s    3    . They both tell what happened to the writer that day. So what makes a blog different     4     a diary?

The     5     (big) difference is that a blog is much more popular than a diary. People like to write in blogs     6     they know their friends will read what they write. If my sister writes in her blog “Nobody     7    (care) about me”, her best friends     8    (read) quickly and tell her how     9    (much) they like her. Blogs help people stay in touch with their friends and know what people     10     (round) them are doing.
