七年级上册阅读理解（专项练习三）请认真阅读下列材料，从材料后各题所给的A.B.C、D四个选项中，选出最佳选项。

AWhat inspires (鼓舞) you to work hard? Having your own goals is important. Good sleep also helps. But as it turns out, having a plant on your desk can improve (提升、改进) your work as well.Mike Robinson, an engineer from Canada, owns his own small company. One day, his wife suggested picking out some plants and putting them on his workers’ desks.Robinson doubted (怀疑) the idea at first. What good would plants do? He thought they might even be distracting (让人分心的). But he decided to try out the idea.First, Robinson bought 20 plants for his workers. He asked each worker to make a small sign that said―My name is ______ and write their own name on the sign. Then, they put the sign on the plant they chose and took it back to their desk. Soon Robinson found that his workers were working much harder and getting along much better than before. It could because his workers formed (形成) “friendships” with their plants. They would take good care of them, and in turn, take more care with their work. Plants can help to create a relaxed atmosphere (氛围) as well.What about you? Does your classroom have any plants? If not, you might want to ask your teacher about this.You and your classmates could take turns taking care of some plants in your classroom? It could be a nice way to make your classroom more lively and get to know your classmates even better.1．What did Robinson think of his wife’s suggestion at first?A．His company was too small to do it.B．He didn’t think it would be different.C．He thought it would cost too much money.D．He didn’t want to try it.2．What did the workers write on their signs?A．Robinson’s name.B．Their plant’s name.C．Their company’s name.D．Their own names.3．Why did the workers work harder and get along much better than before?A．Because Robinson gave them much more money than before.B．Because looking after plants helped them take more care with their work.C．Because the plants helped the workers become good friends with each other.D．Because Robinson’s wife helped create a relaxed atmosphere for the workers.4．In the writer’s opinion, having plants in the classroom ________.A．creates a crowded atmosphere B．takes up too much timeC．helps students build good friendships D．distracts students from their studies5．The story is mainly about _________.A．how to get inspiration for your work B．how having a goal helps with your workC．why good sleep is important for your work D．how plants can improve your workBA little Asian elephant became a big topic in China. Her name is Molly.On March 20, 2016. Molly was born at the Kunming Zoo in Yunnan. Everyone liked her. They called her Little Princess. When she turned 1 year old, the zoo held a big birthday party. The baby elephant got her name and a big cake.But in 2018, the zoo took Molly away from her mom. They sent Molly to Swan Lake Ecology Park in Qinyang, Henan in exchange for another elephant. Life got hard for Little Princess. She had to do tricks and carry tourists on her back. Her keepers tied her up. They even used iron books to make her perform (表演). There were many wounds (伤痕) on her body.Seeing that, people did many things to save her. They posted pictures and articles of Molly online. They asked to send her back home. And they also asked to stop elephant performances in China. Some actors joined in.With their help, Molly finally left the ecology park in Henan, She went back home on May 16. There, her family waited for her. Later, the doctors will give her a check-up. Little Princess will be loved again!6．When did Molly get her name?A．In 2023.B．In 2018.C．In 2017.D．1n 2016.7．What can we know about Molly from Paragraph 3?A．She lived with her mom.B．She had to perform for tourists.C．She lived in the pack as a princess.D．She made friends with other animals.8．What is Paragraph 4 mainly about?A．Why people love elephants.B．What people did to save Molly.C．How actors perform with elephants.D．Where people can enjoy elephant performances.9．Which can be the best title for the article?A．Princess returns home B．Animals shouldn’t performC．How to protect elephants D．The reasons for checking elephantCChinese people don’t just love cooking delicious vegetable dishes. They also love planting vegetables. Chinese people grew vegetables in their gardens centuries ago. Now, they also grow vegetables in the Antarctic (南极), and even in space (太空)! Here is why.With so much land, China is good for growing vegetables. Many places have the light, soil (土壤) and water that vegetables need.Most of today’s vegetables were once wild (野生的) plants. Chinese people started to eat and plant them quite early. The Book of Songs(《诗经》), written 2,500 years ago, says something about vegetables. Chinese people were also open to vegetables from other countries. Potatoes, peppers and tomatoes were all from other places. But Chinese people planted them, making them popular vegetables in China.In the old times, poet Tao Yuanming lived in the countryside and did farm work. This surely included planting vegetables. He loved this peaceful life. Now planting vegetables is a good way to get away from the busy city life.10．What does Paragraph 1 mainly tell us?A．Chinese people love planting vegetables.B．People plant vegetables only in the gardens.C．Chinese people don’t like cooking vegetables.D．People began planting vegetables only years ago. 11．Why is China a good place for growing vegetables?A．Because vegetables are good for people’s health.B．Because China is a big country with a long history. C．Because there’s much soil, light and water in China.D．Because Chinese people do well in growing vegetables.12．The underlined word “peaceful” in Paragraph 4 probably means ________.A．helpful B．quiet C．strange D．important13．Which of the following is TRUE according to the article?A．All today’s vegetables were once wild plants.B．Only Chinese people like growing vegetables.

七年级数学上册动点问题专项练习七年级数学上册动点问题专项练明确以下几个问题：1.数轴上两点间的距离，即为这两点所对应的坐标差的绝对值，也即用右边的数减去左边的数的差。

例如，数轴上两点的坐标分别为a和b，则它们之间的距离为|a-b|。

2.点在数轴上运动时，由于数轴向右的方向为正方向，因此向右运动的速度看作正速度，而向左运动的速度看作负速度。

这样在起点的基础上加上点的运动路程就可以直接得到运动后点的坐标。

即一个点表示的数为a，向左运动b个单位后表示的数为a-b；向右运动b个单位后所表示的数为a+b。

3.数轴是数形结合的产物，分析数轴上点的运动要结合图形进行分析，点在数轴上运动形成的路径可看作数轴上线段的和差关系。

基础题1.如图所示，数轴上一动点A向左移动2个单位长度到达点B，再向右移动5个单位长度到达点C点。

1）求动点A所走过的路程及A、C之间的距离。

动点A所走过的路程为2+5=7个单位长度。

A、C之间的距离为|(-2)-1|=3个单位长度。

2）若C表示的数为1，则点A表示的数为5.2.画个数轴,想一想1) 已知在数轴上表示3的点和表示8的点之间的距离为5个单位，有这样的关系5=8-3，那么在数轴上表示数4的点和表示-3的点之间的距离是1个单位。

2) 已知在数轴上到表示数-3的点和表示数5的点距离相等的点表示数1，有这样的关系1=|(-3)+5|，那么在数轴上到表示数a的点和表示数b的点之间距离相等的点表示的数是(a+b)/2.3) 已知在数轴上表示数x的点到表示数-2的点的距离是到表示数6的点的距离的2倍，求数x。

由于|x-(-2)|=2|x-6|，所以x=-5.应用题1、已知数轴上有A、B、C三点，分别代表-24，-10，10，两只电子蚂蚁甲、乙分别从A、C两点同时出发相向而行，甲的速度为4个单位/秒。

⑴问多少秒后，甲到A、B、C的距离和为40个单位？设甲到B的距离为x，则甲到A的距离为24+x，甲到C的距离为34-x。
