The bad words, however, encouraged her to write a story about her hair and she hopes it will make other young people be proud of who they are.Tiana wrote My Afro: Twin Best Friends when she was seven. It tells the story of Tia and her best friend Aaoki, who has the same type of hair as hers, “while everyone else ha s straight, curly or silky hair.” In the book, Tia and Aaoki like to dress and style their hair the same, but Tiana’s own Afro hair can be hard to manage. She said, “I wanted to show that people who have my type of hair have challenges and sometimes find i t hard to love their hair.”The young writer has been writing since she was three. Now, Tiana's book has sold more than 700 copies and she plans to write more stories. Her mum, Dorothy, as her very first reader, says Tiana's stories are encouraging and she gets to know more about her daughter through her stories. Tiana says she's had lots of replies from readers who also had trouble accepting their hair and it feels great to know that they are now confident to wear their special but lovely hair to school. Tiana also received a letter in the post saying sorry for the bad words he said years ago. Realizing who wrote this letter at once, Tiana smiled brightly.6. Why did Tiana write the book?A．To relax people with straight hair. B．To tell the story of her best friend.C．To share the secret of managing hair. D．To make people take pride in themselves.7. When did Tiana write the book My Afro: Twin Best Friends?A．When she felt hurt. B．When she was three.C．When she was seven. D．When she met Aaoki.8. How does her mum describe Tiana's stories?A．Tiring.

Manners have developed over thousands of years andare always changing. Around 100 years ago, children weren't allowed to speak unless parents spoke to them first. Now young people can make their voices heard in many places.Manners also mean different things in different countries. Eating food loudly is considered rude in some countries, but in others it's a sign that people are enjoying their meal. What do you think, are manners important?Many old people think so. They say kind words and actions are good to everyone. When someone has good manners, it shows they care about other people's feelings and want them to be comfortable. In other words, well-mannered people make the world a happier place. Manners also help keep everyone healthy, which is why people should cover their mouths when they cough and keep dirty feet off seats.However, some young men don't think so. They hold the idea that manners make people act in a way that doesn't mean how they really feel. If someone says “thank you” or “sorry” when they don't mean it, they're not being polite. In Europe, manners were a way of showing how rich a person was, but does it really matter what type of knife people use to eat fish? As long as people are kind to others, they should be allowed to act how they like.11. Why are the table manners mentioned in Paragraph 1?A．To start the topic. B．To keep the tradition.C．To show the importance of them. D．To tell the young about them.12. How is the passage developed?A．By comparing. B．In the order of time.C．By listing numbers. D．In the order of space.13. What is the main idea of Paragraph 3?A．We need to care about others. B．Good manners are very important.C．Well-mannered people make us happy. D．You can be healthy with good manners. 14. What do some young people think of good manners?A．They are easy to follow. B．They are very necessary.C．They make people more relaxed. D．They are less important than being kind.15. What can we infer from this passage?A．Saying sorry certainly means being polite.B．Eating fish with a knife shows you're rich.C．Coughing with the mouth covered is strange.D．Eating loudly can be good manners sometimes.People across the UK have enjoyed the sunshine this week, but they have also been advised to be careful as a heatwave hits much of the country.A heatwave is a period of unusually hot weather, especially one that continues for a long time.They usually happen in summer. However, as the main cause of heatwaves, climate change is increasing the chance of heatwaves happening and making them worse. Compared with the UK, the present hot weather is even more extreme in some European countries – temperatures in southern Spain have reached 41 ℃.Heatwaves can be a great danger to people’s health, especially for the elderly, children and people with certain health conditions. However, anyone can be influenced by such heat. A group of UK scientists have suggested that, just as storms are given names, we should name heatwaves in order to raise awareness （意识） of the health risks.The Met Office, the UK's national weather service, has given a warning about the possible results caused by heatwaves. Temperatures are expected to rise to 35°C, and the record for the UK’s hottest day could be broken. To deal with hot weather, the MO says people should try to stay at home between 11am and 3pm, when temperatures are at their highest and the sun is strongest. Make sure you wear a hat and drink plenty of water. If you are swimming outdoors to cool down, make sure you're with a trusted adult and follow local safety advice.16. What mainly causes heatwaves?A．The health risk. B．Climate change.C．The human activity. D．High temperature.17. What does the underlined word “extreme” probably mean in Paragraph 2?A．serious. B．lovely. C．comfortable. D．difficult.18. Why did scientists suggest naming the heatwaves?A．To put them under control.B．To protect children from them.C．To stop people from worrying about them.D．To make people realize the health risks out of them.19. What advice did the MO give the people in the UK?A．Swim indoors. B．Wear sunglasses.C．Drink much water. D．Stay with friends.20. What can we learn about a heatwave from the passage?A．It is also known as a storm. B．It has only hit the UK so far.C．It often lasts a very short time. D．It does harm to people's health.I love reading. I ______ over seven hours a week reading different types of books. On weekdays, I usually read for about an hour before going to bed. I read a lot at the weekend. I am interested in history books, but I like novels best. I get most of my books from the library, so I have to ______ them after reading.
