We usually believe what our brain tells us, but there are some amazing facts which show that the brain tricks us. As a result, we think we can see something that is not actually there or we ignore（忽视）things that actually are there.

 Scientists Daniel Simons and Christopher Chabris have researched this phenomenon（现象）, which they call “change blindness”. Their experiments show how we sometimes just do not see what is in front of our eyes because           42          .

 Here is one of their most famous experiments. In this experiment, the participants（参与者）were shown a video of two groups of people (one group in white T-shirts and one group in black T-shirts) who passed basketballs around in a hallway. Each group had three members. Simons and Chabris asked the participants to count how many times the white team passed the ball. While the two teams were passing their balls around, a person dressed up as a big bear walked through the group and stopped to look at the camera. Simons and Chabris found that about half of the research participants did not notice the big bear.

    In 1826, a Frenchman named Niepce needed pictures for his business .But he was not a good artist .So he invented a very simple camera. He put it in a window of his house and took a picture of his garden .That was the first photo.

    The next important date in the history of photography was in 1837. That year, Daguerre, another Frenchman, took a picture of his reading room .He used a new kind of camera in a different way. In his picture you could see everything very clearly, even the smallest thing. This kind of photo was called a Daguerreotype.

    Soon, other people began to use Daguerre's way. Travelers brought back wonderful photos from all around the world .people took picture of famous buildings, cities and mountains.

    In about 1840, photography was improved .Then photographers could take pictures of people and moving things .That was not simple .The photographers had to carry a lot of films and other machines. But this did not stop them, for example, some in the United States worked so hard. Mathew Brady was a famous American photographer. He took many pictures of great people .The pictures were unusual because they were very lifelike.

    Photographers also became one kind of art by the end of the 19th century. Some photos were not just copies of the real world .They showed feelings like other kinds of art.

    We want to explore and try to better understand the world in which we live; Space exploration is one of the ways. Through the exploration of space, we can begin to unravel the mysteries of our universe, and to better know our living environment.

    Space exploration provides us with knowledge about the beginning of our solar system, our own planet and ourselves. It also helps answer the questions that have puzzled us for many years. Solar system exploration is important because it is good for us.

    Space technology has become an important part of our daily lives. Some technology uses satellites to communicate. Satellites are also used to examine the changes in the Earth's climate and seas, for weather report and for military. We also use satellites in food production. Because of the use of space technology in crops, fewer and fewer people will suffer hunger.

    The space program provides a chance for nations to work together. The cooperation(合作) promotes peace and understanding between governments and their people. Many governments have taken part in the space technology, including the United States, Russia, Japan, the European nations and India. In the near future, other nations will take part in it. In fact, the United States remains the leader in new space technology.

There are many different kinds of jobs around the world. Many of the students have different ideas about their dream jobs in the future.

My name is Yu Sheng. I'm a reporter from the magazine- People's Life in Town. Last Monday afternoon,1 did a survey of the students in Grade 9 in Beijing Junior High School. There are 50 students in the class. And I found some popular jobs that they like. Here is the result.

The engineer is the most popular job. 20% of them want to work as engineers in the future. Nine students would like to be doctors because they want to help people be healthy. Eight of them want to be teachers when they grow up. Five of them are over 180 cm, so they want to be basketball players. Three of them want to be singers and actors. Four of them think they like to be computer programmers and three of them like to be cooks. The others. don't mind what to be.

No matter(无论) what you want to be in the future, study hard from now on.

We drink one of the world's most popular drinks—tea—on May 21, International Tea Day. We all know that China is the birthplace of tea 1 . But do you know about the tea cultures of some 2 countries? 

Tea was brought to 3 from China in the ninth century. Then in the late 12th century, the Japanese monk（僧侣）Eisai 4 tea to Japan from China again, Eisai wrote a book praising tea as a 5 that was especially good for the heart. The custom（习俗）of tea—drinking later became an important part of Japanese culture. In Japan, 6 tea is an art. People use beautiful tea bowls and 7 the peace and calm of the tea room. 

India is one of the largest tea producers in the world. It also learned the art of tea-drinking from China centuries ago. Tea is very 8 in India. In fact, 70 percent of the tea it produces is loved 9 its own people. "Chai" is the Hindi（印地语）word for tea. Traditional Indian chai is a type of 10 tea. But unlike Chinese black tea, chai is 11 together with strong spices such as ginger（姜）. 

Turkey also has a tea culture. If you ever find 12 in Turkey, one thing you have to do is to enjoy special tea there. Tea was brought to the country 13 China in the nineteenth century. The traditional Turkish tea cup is in the shape of a tulip（郁金香）. The tea is 14 served very hot and one has to hold the cup by its lower rim（边沿）. Most often, salty or sweet biscuits, 15 "kurabiye", are served along with the tea.
