The son was full of joy when he saw the sky filled with colorful kites. He wanted to fly a kite, too. The father then bought a kite for him.The son started to fly the kite. Soon, his kite was high up in the sky. After a while, he said, “Father, it seems that the string (线) is stopping the kite from flying higher. If we cut it, the kite will be free and fly even higher. Can we cut it?” The father cut the string. The kite started to go higher. This made the little boy happy.But then, slowly, the kite started to come down. And finally it fell to the ground. The son was surprised to see this. He asked his father, “I thought that after cutting the string, the kite would fly higher. Why did it fall down?”The father explained, “The string was not stopping the kite from going higher, but was helping it stay in the sky. You helped the kite go up in the right direction using the string. But when you cut the string, it could no longer support the kite.”Sometimes, we may feel like there are certain things that are holding us back and stopping us growing. But in fact, these might be the things that support us the most. 21．How did the boy feel when he saw the colorful kites?A．Strange.B．Happy.C．Relaxed.D．Surprised. 22．Why did the son want to cut the string?A．Because he preferred to use a longer one.B．Because he found the string was not strong.C．Because he liked the string.D．Because he thought the kite would fly higher.23．What can we learn from the passage?A．We can fly kites in our free time with our parents.B．Flying kites can make people healthy.C．The things that hold us back can also support us.D．Children like flying kites.Let’s Explore the Nature!Spring is coming!

It is a new network after 1G, 2G, 3G and 4G and it can connect everyone and everything together. 5G means super-fast data (数据) speed. One can download a two-hour movie in fewer than 10 seconds, and it is making our lives more and more convenient.5G will make self-driving cars possible. For safety, self-driving cars need super-fast data transmission (传输) to communicate with their nearby environment. 5G is just what makes self-driving cars achieve this. Even airplanes will become “smart” in the near future.5G will be a big help for students who take online classes. Students all over the world will be able to see places like the Great Wall without leaving their rooms.It will be also easier for doctors to treat patients remotely by 5G. It means caring for patients from far away.The facts listed above are only part of what 5G will make possible and popular. Just as in the early days of the Internet in the 1990s, few could see how it could change the world. The same will surely be true of 5G. With 5G, many things do not seem like dreams to anyone. Now let’s get ready to say goodbye to 4G and welcome the coming of 5G.27．How long may it take to download a two-hour movie with 5G?A．15 seconds.B．8 seconds.C．10 minutes.D．2 hours. 28．From the last paragraph, we can know that ________.A．4G is no more used in our daily life now B．the writer is worried about the coming of 5GC．with 5G, some of our dreams will come true for sure one day D．in the 1990s, all the people believed that the Internet would change our life29．5G will make the following things more and more popular EXCEPT ________.A．self-driving cars B．“smart” airplanes C．online classesD．hospitals with doctorsZhang Guimei show us how to be a good teacher and the importance of a teacher in students’ lives.In 2009, Zhang Guimei founded the Huaping High School for Girls in Lijiang, Yunnan Province. This is a special high school which did not ask for tuition fees (学费) from girls in poor families. In 2003, Zhang began to raise money for the school, but her efforts were often met with suspicion and even misunderstanding. During 2003 and 2007, Zhang spent her sparetime asking people to make donations (捐款) for her school. However, the money she got was not enough. In 2007, after her dream was reported by the media (媒体), the government promised to help her project.Zhang carries on strict school rules. She plans every minute of her students’ timetable. At 5:20 a. m., she wakes up all the girls. They must take a nap in the afternoon. They are only allowed three hours a week outside of the school. And long hair is not allowed in school. She wants to change the lives of many girls from poor families through education.Eleven years later, over 1,600 girl students have graduated from the school and received higher education-including many famous universities in China.When people asked why she made so many efforts to help girls in the mountains to receive better education, she just said, “I believe it is really important for girls to receive education. I hope they can live happier than me. And it will be the greatest comfort to me.”30．When was the Huaping High School for Girls set up?A．In 2003.B．In 2005.C．In 2007.D．In 2009. 31．What does the underlined word “suspicion” in Paragraph 2 mean?A．Support.B．Understand.C．Doubt.D．Trust. 32．What does the third paragraph mainly tell us?A．All the students get up early to study.B．There are strict rules in the school.C．Long hair is not allowed in the school.D．Zhang is a kind mother for the students.33．Why did Zhang make so many efforts to help those girls?A．Because she was asked to do so by their parents.B．Because she thought girls were as clever as boys.C．Because she wanted them to live more happily than her.D．Because those girls’ parents had paid lots of attention to their study.34．What is the best title for the text?A．A Good And Strict Teacher B．A Common High School for GirlsC．A Famous High School in China D．Girl Students from Poor Families四、多任务混合阅读阅读短文，并按要求完成下面小题。
