What time of day can you think most quickly? Are you a morning person?" Or does it take you a few hours to get your brain going? A lot of recent research suggests that we should pay attention to our body clock. It can tell us what time of day we can perform best at.

    Many people work best later in the morning. This is because the body's temperature takes time to rise through the day. Taking a warm shower when you wake up can help your body's temperature rise quickly.

    But everyone's body clock is different and some are special. Morning people will get up early and work better early in the day." Evening people will work later, but work better towards the end of the day.

    Research shows that we're better at some activities at certain times of the day." Physical performance is at its best between 3p. m. and 6p.- m.-,- so it's better to exercise later in the day.

    Between noon and'4p. m. , people begin to pay less attention. This is because we think less quickly after, a big meal. Research also shows we become sleepy around 2 p.m. This is why people in Spain take a short sleep in early afternoon.

    Finally'it is best to eat when we' re active. This allows our body to burn calories (卡路里) better and stops our blood sugar levels from getting too high.

    Benjamin Banneker was born a few months before another great American—George Washington. Benjamin was black, but he was not a slave (奴隶). He and his mother and his grandmother were free. Benjamin's grandmother came from England. In America she got a job and worked for many years to pay for her boat trip across the ocean. After working many years, she saved enough money to buy a farm. Benjamin lived with her for a while. She taught him to read, write and do arithmetic (算术).

    Benjamin's neighbours knew that he was clever. They were not surprised when he built a large wooden clock. He made each piece after studying a small pocket watch. The clock made him famous, for it was one of the first clocks built in America. People from other places began to send hard problems of all kinds to Benjamin to settle.

    Thomas Jefferson heard of Benjamin Banneker's ability to settle hard problems. He asked Banneker to help build the city that was to be the capital of the United States—Washington, D.C. Banneker worked hard on the plans for the city. He marked where the streets and buildings—the Capitol (美国国会大厦), the White House, and many other places should be built.

    Later, L' Enfant, the Frenchman who had designed the new city, had a quarrel, and went back to France in anger. He took all of the plans away. The workmen couldn't build without any plans to follow.

    For a while it seemed that the plans for the capital might have to be changed, but Benjamin Banneker remembered the plans he had helped draw. He drew each again as he had built each piece of his clock.

    If it weren't for Benjamin Banneker, Washington,

    D.C might look very different from the way it does today.

Now people have more money than before, and they want to enjoy life. {#blank#}1{#/blank#} Listen! Some people are talking about their vacation plans.

 A relaxing vacation! I can't wait! 

A. I want to buy lots of beautiful clothes. 

B. Now he really wants to get some rest,

C. Many people can come to buy clothes in my shop.

D. We can exercise and enjoy lots of interesting places.

E. But a lot of people like traveling in the countryside.

F.I hope the beauty of nature can help me to forget all of my problems.

G. So people have difference ideas about how to enjoy their vacations.

What are on your desk? Your model planes? Your picture books? Some kids say reading is good. Books are important to them. Do you like reading? What about reading to a cat or a dog? 

To make* boys and girls open their books and love reading, the Acton Memorial Library lets boys and girls read to a dog every Monday afternoon. In the picture is a boy with a dog. The boy is Stone. He reads to a dog in the library. He thinks reading to a dog is fun. The name of the dog is Molly and she is 5. She isn't black or white. She is brown. She is a reading dog and her job is to make boys and girls like reading. 

The reading dog is nice and all the people love her. Many boys and girls love reading to her, so she is very busy*. Do you want to read to her, too? Come to the library in America!

Hello! My name is Linda Green. I'm a girl. This is my notebook. It's a yellow notebook. How do you 1 it? N-O-T-E-B-O-O-K. That is my schoolbag. My pencil box, a dictionary and a watch are 2 it. My pencil box is red. Three 3 are in it. Look! That is my dictionary. It is 4 English dictionary. It is blue. What color is the watch? It is brown. It's nice. An ID card is in 5 schoolbag, too. It isn't my ID card.6 is on my desk. It's Mike's. His 7 is on it. I will (将会)8 him. His phone number is 8372 - 9810. Oh! What is that? It is a key. Maybe it is Mrs. White's. She 9 a key yesterday. Mrs. White is my English teacher. She has a daughter and a son. Her daughter is Sally. Her 10 is Bob. They are in my middle school, too.

Nowadays, we have kinds of technologies to protect us from different disasters（灾难）. We even know where and when some disasters, like the typhoon, come. While most of the new technologies are far away from us, some around us can help people in disasters.

The drone（无人机）is one of them. It can be used to send food, water and other important things when a natural disaster happens. Very often the buildings are too dangerous for rescue teams to get in. They can make the drone fly into the buildings to search for those who are still alive first.

Social media is also a useful tool when it comes to natural disasters. With its help, people can know about the natural disasters before they hit. And some social media platforms allow people to mark themselves as safe after disasters so others can know their status.

 Social media is also a place for up-to-the-minute news, so people can learn what is going on in the disaster areas. Besides, many social media platforms allow people to donate money to help people in disaster areas. The money will help them get back to their normal life as soon as possible. For example, livestreaming（直播）helped raise a lot of money for Henan after the flood in 2021.

Although these technologies can help when there is a natural disaster, we still need to prepare necessary tools and learn important skills to protect ourselves.
