Mark and Betty are brother and sister. They love to play on the1. They think it's very2to play there. They go to the beach by3every weekend. They live far away from the beach, so their father usually4about two hours driving them there.

    Last Sunday their father was very5and couldn't send them to the beach. Mark and Betty6very bored at home. They thought they must solve (解决) the7quickly.

    Then Mark came up with an idea and said to his father, "I have a good8, Dad. We can live near the beach. Then Betty and I can go there every day, and you don't need to drive us there."

    His father looked at him up and down and smiled, "Sounds really good. But the houses near the beach are very9. I must work hard to buy a10. Then you can go to the beach every day."

   Phil White has just returned from an 18,000-mile, around-the-world bicycle trip. White had two reasons for making thisepic journey. First of all, he wanted to use the trip to raise money for charity, which he did. He raised £70,000 for the British charity, Oxfam. White's second reason for making the trip was to break the world record and become the fastest person to cycle around the world. He is still waiting to find out whether he has broken the record or not.

   White set off from Trafalgar Square, in London, on 19th June, 2004 and was back 299 days later. He spent more than 1,300 hours in the saddle (车座) and destroyed four sets of tyres and three bike chains. He had the adventure of his life crossing Europe first, and then the Middle East, Asia, Australia, New Zealand, and finally the Americas. Amazingly, he did all of this with absolutely no support team. No jeep carrying food, water and medicine. No doctor. Nothing! Just a bike and a very, very long road.

   The journey was lonely and desperate at times. He also had to fight his way across deserts, through jungles and over mountains. He cycled through heavy rains and temperatures of up to 45 degrees, all to help people in need. There were other dangers along the road. In Iran, he was chased by armed robbers and was lucky to get away with the little money he had. The worst thing that had happened to him was having to cycle into a headwind on a road that crosses the south of Australia. For 1,000 kilometers he battled against the wind that was constantly pushing him. This part of the trip was slow, hard and depressing, but he made it in the end. Now Mr. White is back and wants to write a book about his adventures.

There is a very important place in my life. That is my grandpa's 1 . My grandpa lives in a small village (村庄). The village is far 2 the city. It is at the foot of a hill (小山)with all kinds of flowers, 3 it's very beautiful. There are many trees on the hill, too. The air in the village is very fresh.  There are many 4 , at my age in the village. When I go to my grandpa's home in the summer holiday. I always play with 5 . We often play football, sing and dance. The children are very 6 to me and I'm happy to be with them. Sometimes they come to my grandpa's home to visit me. We sit under a big tree in front of my grandpa's house to 7 my grandpa's interesting stories. Sometimes I take my computer with me to my grandpa's home. I teach them how to use the computer. They all like to watch soccer games on the 8 with me. We become very good friends soon. Now many workers are building(修建) a wide road through the 9 . The traffic will be very easy. I'm going to spend (花费) my summer holidays in my grandpa's home every year because I 10 my grandpa and my good friends. I also miss my grandpa's house very much. 

Fleming saw many soldiers die from infections (感染) in their wounds as he worked in a hospital during World War I. This made Fleming decide to find a way to help the body fight infections. 

In September 1928, Fleming left some glass dishes on a bench in his laboratory for two weeks. When he came back, he noticed something puzzling. Bacteria (细菌) were growing on all the glass dishes except one. On this dish mould (霉菌) had started to grow—the kind found on old bread. The mould seemed to be giving off something that stopped the bacteria from growing. Fleming called it "mould juice". He tried it on other bacteria, and it killed them, too. Fleming became wild with joy and named it penicillin. 

Unfortunately, Fleming's boss thought he was wasting his time and it was impossible to kill bacteria at that time. Fleming did a few more experiments with penicillin, and he also wrote about it so other scientists could learn about it. However, because no one seemed interested in his discovery, he forgot about penicillin and started to work on other things. 

In 1939, Ernest Chain, a scientist, and his boss, Howard Florey, were looking for medicines that could kill bacteria. They discovered Fleming's notes and decided to test penicillin. In 1940, they gave penicillin to some sick mice, who survived later. But those who didn't get it died. Florey declared: "It looks like a miracle!" By 1943, the final tests on humans were finished successfully and the world had its first antibiotic (抗生素) medicine.

Daisy forgot to set the alarm clock (闹钟) so she had to run to catch the bus. This made her feel tired and rushed when she started her science test. After she handed in her test paper, she was certain that the test had not gone well. With a heavy heart, she left the classroom.

That afternoon, Daisy left school to work part-time at Beckman's. After she finished her work, Mrs. Beckman called her into the office. "Daisy," she said, "you have been a great worker. But business has been slow; we have to let you go."

Feeling down, Daisy left the office. As she walked slowly towards her aunt's house, she tried to think about the new hairstyle her aunt had promised her. When she arrived, Daisy showed her aunt a picture of the style she wanted.

"Well, you're done. What do you think?" Her aunt asked about an hour later.

What Daisy saw in the mirror left her speechless. It was nothing like the picture! How could she possibly go to school again?

The next morning, putting her things in her locker, she ran into Ms. Wilson, her science teacher.

"I know, Ms. Wilson, I did very poorly on the test. It's just that I forgot…"

"What are you talking about? Daisy, you did a great job!" Ms. Wilson said. "What I wanted to ask you is if you would be interested in working a few days a week after school as a lab assistant (助手). I need some help organizing all the materials." Daisy happily accepted.

"Daisy!" she heard as the rest of the students began to enter the building. "Where did you get your hair done?" She was so excited about her test and new job that she had completely forgotten about her hair.

"Wow! That is so cool!" she was told. She couldn't believe her ears. Everyone loved her hair.

What a couple of days it had been! Walking home, she smiled as the radio of a passing car played the song "What a Difference a Day Makes".

 It's 2: 30 in the afternoon. The house is quiet(安静的)." Tom?" Mom says. No one answers.

 Mom comes to Tom's room. He is not on the bed, but his model plane is on the desk." He is not in his room, and he is not in the yard, " Mom thinks. Then Mom comes to his grandparents' room. Tom likes to play with his grandpa's tape player, but he is not there.

 Mom looks for Tom everywhere. Where is Tom? Mom is worried. She wants to call Dad. She comes to the living room to get the phone.

" What's that? " Mom sees something black under the sofa. Oh, it's Eric, Tom's dog. It loves sleeping there. What is next to Eric? It's Tom!
