Here are four of them. Let’s have a look. The Smart Schoolbag Forget to pack the books you need into your schoolbag in the morning rush?A schoolboy invented a schoolbag. It tells you which books to pack. A small computer and a scanner (扫描装置) are fixed in the bag. As each book is put into the bag, the scanner checks it. If any book is missing, a message will be shown on the computer screen to remind you. Weather Sweets Can you eat weather?A university makes that happen. It uses a 3D printer to create sweets based on the weather information of a certain day. The shapes of the sweets are influenced by wind speed. The colors of the sweets are decided by temperature. The sweets act as a weather record of the day when they are made. The Sunrise Bed It’s hard for you to get up in the morning, isn’t it?To help you get up, a company has created a “tool”—a sunrise bed. It wakes you up gently as sunrise does. Lights built into the bed turn on and start to get brighter and brighter. When the lights are fully on, soft music will begin to play. It’ll be louder and louder until you turn it off. Lip (唇) Reading Machines The Chinese Internet Company Sogou has made lipreading technology. The machine turns your lip movements into voice or text. This could be very useful if you are in a noisy place. 16．Who invented the Smart Schoolbag? A．A reporter. B．A schoolboy. C．A university. D．A company. 17．What affects the shapes of the weather sweets?

"I got the idea when I saw my grandmother, in her 70s,working hard to harvest lotus roots under the hot sun,"Yang said. Sometimes, his grandmother would badly hurt her fingers while using harvesting tools. To make things easier for his grandmother,Yang decided to invent a robot that could do the job for her. With the help of his teacher, Hong Wei, Yang spent almost a year building a model of the robot. The robot can move by itself in the muddy（泥泞的）fields where lotus roots grow. It uses special technology to identify（识别）ripe roots by looking at the colour of the lotus leaves. Then, its arm carefully cuts the roots without breaking them. While creating the robot, Yang faced challenges like collecting parts for the model, putting them together and using a hot glue gun for connecting. "The first time I used a hot glue gun, my hands were shaking," Yang laughed. At first, he planned to use rotating blades（旋转叶片）for harvesting lotus roots. But it was hard to find them, so he used more common blades instead. When Yang showed the robot to his grandmother, she was happy and gave helpful suggestions for improvement. She suggested using a voice player to help find the robot in thick lotus leaves. "My grandmother's suggestion reminded me that any invention must be practical to be truly valuable."said Yang. Although Yang still needs to make improvement, like finding cheaper materials, his teacher Hong spoke highly of Yang's creative thinking and resolution to help his grandmother. 21．What does the underlined word "It" in Paragraph 4 refer to? A．The robot. B．The muddy field C．The ripe root. D．The lotus leaf. 22．How many challenges did Yang meet during the invention process? A．5. B．4. C．3. D．2. 23．Put the following information into CORRECT order according to the passage. a．Yang had the idea to invent a machine to make harvesting easier for his grandmother. b．Yang's grandmother would hurt herself while using harvesting tools sometimes. c．Yang's grandmother offered suggestions to improve the machine. d．Yang spent nearly a year building a model of the machine. e．Yang kept on improving the machine better.

D．Hard-working,caring and creative. 25．Which would be the best title for the passage? A．Growing New Ideas: A Student's Gift to His Town B．A Teen's Invention to Help His Grandmother's Work C．The Harvesting Robot:A Teen's Invention for Farming D．A Young Inventor's Journey to Making a Useful Machine C The toothbrush is a common thing that most people use every day, but how much do you really know about this seemingly simple tool? Believe it or not, the toothbrush has a very long and interesting history. The first toothbrushes were actually small twigs（嫩枝）that people would chew（嚼）on one end to soften the bristles （短而硬的纤维）. These bristles were then used to clean their teeth. The first "modern" toothbrushes were made in China around 1498．These toothbrushes were made of pig hair and were much more comfortable to use than the twigs. In 1780,William Addis of England came up with the idea of making small holes in a bone and putting bristles into the holes. He then glued the bone to a handle（柄）. This design worked much better than the twigs and pig hair brushes and quickly became very popular. In 1845, the first toothbrush that was produced in large numbers was created by H.N. Wadsworth.His toothbrush was made of bone and bristles and was very similar to William Addis' design. The first nylon（尼龙）toothbrush was created in 1938 by DuPont. Nylon bristles were much more effective at cleaning teeth than natural bristles and quickly became the standard. Today, toothbrushes come in all shapes and sizes and are made from all kinds of materials. You can even buy electric toothbrushes that do all the work for you! Who would have thought that such a simple tool could have such an interesting history? The next time you reach for your toothbrush, take a moment to think about all the people who have used a toothbrush before you and all the people who will use one after you. 26．What's the purpose of writing Paragraph 1? A．To lead in the topic. B．To provide the background. C．To compare differences. D．To introduce different toothbrushes. 27．What did people usually do with the twigs before brushing their teeth with them? A．hey chewed on them B．They cut them into two pieces. C．They glued them to a handle. D．They made small holes on them. 28．The first tooth brush that was produced in large amounts was invented by A．William Addis B．H.N. Wadsworth C．DuPont D．Anthony Wood 29．What is the right structure of the passage?②=Paragraph 2,...) 3．What's the passage mainly about? A．The importance of the toothbrush. B．Suggestions on using the toothbrush. C．Different opinions about the toothbrush. D．The interesting history of the toothbrush. 第二节（共5小题，每小题2分，满分10分） 阅读短文，从方框内所列选项中，选出最佳选项填入对应空白处，使短文通顺、连贯。（选项中有一项多余） Creativity is not a born talent.

Here is how different cultures developed and improved their designs. The first pillows were invented around 9,000 years ago by the ancient Mesopotamians, which were made of stone and carved into a cradle（摇篮）shape. They were not designed for comfort. Interestingly enough, these stone pillows were used to lift the head so that insects wouldn't fall into a sleeper's mouth, nose or ears! Because the stone was expensive, only people who had a lot of wealth and influence could own the pillows. In ancient Egypt, people believed the head was the center of spiritual life and it should be paid attention to and protected.Egyptian pillows were made of ivory, wood or stone. The ancient Chinese had the ability and knew how to create soft pillows, but they liked hard pillows better. And porcelain（瓷）pillows are among the best preserved from historical records, which were produced in the Sui Dynasty for the first time, became popular during the Tang Dynasty and reached the top in the Song Dynasty. Today, there are various pillows for people to choose from. However,rubber（橡胶）pillows are without doubt the top-selling products around the world. Because they fit the shape of your head and neck, help you sleep better, and last a long time. In addition, they are eco-friendly.
