It was l sunny Sunday afternoon. John's parents were not in. John decided to go to the Happy Theater to watch a talent show, so he 1. Only Barky, John's pet 2stayed at home. Just after John left, a bad person 3 the window, and then he came into the house 4it. He began looking for expensive things in the rooms. He found some 5in a box. He took out the money, but as he was leaving, he 6 a dog's barking (叫声). He looked around and found Barky looking at him angrily. He was very scared.

    Barky was about to bite (咬) him when John came home. John let Barky sit down and told the bad person, "Come with me to the 7, or Barky will bite out!" So the bad person had to 8 John to the police station with Barky close behind. A 9put handcuffs on (给...戴上手铐) the bad person after John told him the thing.

    Barky had a(n) 10 for watching the house. But the bad person didn't know.

People know animals do have feelings, but they are not sure if these feelings are correctly understood. In recent years, scientists have done research about the feelings of cows, frogs and pandas.  ▲  It says that humans can tell whether a chicken is happy or sad by listening to its calls.

The researchers put a bowl behind a door. Inside the bowl, sometimes, there was something chickens love to eat, such as rice or insects. Sometimes, there was nothing. When the chickens saw food behind the door, they seemed happy and produced fast and loud sounds, known as food calls. When there wasn't food, the chickens made low and long noises to express disappointment. The researchers recorded all these sounds and studied their waves.

Then the researchers chose 16 recordings of such chicken noises. Half were from the chickens seeing the food and half were from the chickens finding no food. The recordings were played to 194 volunteers. Sixty-nine percent of the volunteers correctly understood whether the chickens were feeling happy or not, and some of them even had no experience of taking care of chickens.

The result shows that humans have the natural ability to understand the feelings of chickens. Hopefully, this finding can bring about new technology to help with chicken-raising, a big industry in many countries. Some scientists are already working on a smart computer program that can identify chickens' feelings. This is good news for farmers who want to make the birds happier and healthier.

How do you keep cool during summer? Air conditioning(空调) and electric fans are good tools in modern society, But before that, people could only use tans.

Over 3, 000 years ago, the first fans began to be used. They were made of feathers(羽毛) bamboo or silk. They came in different shapes, including round and square.

Later, with the invention of paper, folding( 可折叠的) paper fans became popular during the Song Dynasty. There are usually beautiful pictures on fans. Some are landscapes(风景). Others are flowers and animals. Moreover, many great people including Su Dongpo, a calligrapher(书法家) and painter of the Song Dynasty, and Tang Yin, a poet and painter of the Ming Dynasty, once painted their masterpiece (杰作) on fans. The made fans not only useful tools in daily life but also great artworks.

Therefore, with its value of beauty, people take the fan as a symbol of status (地位). That's why in old China, emperors(皇帝) and scholars often held fans.

Today, fans are also great collectors' items and gifts. On the opening ceremony of the 2008 Beijing Olympic Games, folding fans were given to leaders and officials of other countries, as well as other audience. While they were waving fans to get cool, they were also experiencing Chinese culture.

Emma was nervous about the ceremony. She was the valedictorian(致告别辞者) for their class, and she was {#blank#}1{#/blank#}(worry) about speaking in front of such a large audience(观众). Emma wanted to practice her speech one more time with Julie.

But {#blank#}2{#/blank#} was Julie? Emma looked everywhere, but she couldn't find her. She called Julie's cell phone and sent her a few text {#blank#}3{#/blank#} (message), but Julie didn't answer. Emma didn't have much time, so she practiced her speech behind the curtains in the hall. Nobody saw her.

When it was time {#blank#}4{#/blank#}(line) up for the ceremony. Emma finally saw Julie." Where have you been?"

Emma asked Julie." I {#blank#}5{#/blank#}(call) you five times!"

" Sorry, I didn't hear my phone," replied Julie.

" Where have you been? I {#blank#}6{#/blank#}(look) for you, too."

"I was in the hall, practicing my speech," said Emma.

" Where? I didn't see you there," said Julie.

"I was behind the curtains," Emma said and laughed." That's why you couldn't find me!"

Julie laughed, too." Don't worry. You' ll do {#blank#}7{#/blank#} great job!" They took their seats. Emma sat in the front row. She was still {#blank#}8{#/blank#} (real) nervous. Then, someone handed her a piece{#blank#}9{#/blank#} paper. It was a note from Julie! It said," Good luck! You can do it!" Emma felt better and smiled.

" Sometimes paper is the {#blank#}10{#/blank#}(good) technology!" she thought.
