It stops things for a while,” says Joe.Stephen says recovery was a slow six-month process and changed the course of the band completely.“The accident has changed my attitude towards life. It has given me more motivation towards the band. I want to make it a bit more now. I know what I want and I want to get it. ”Tony says the crowd reactions to Stephen playing rhythm guitar in his wheelchair are always amazing.“It's not a big issue but people seem to remember and they say it's amazing he gets up and does it and doesn't just give up,” he says.“We don't look at him as having a disability at all. He just sits down while he's playing, and that's all. ”Stephen said the first time he went on stage as a paraplegic (截瘫患者), he felt out of place, but quickly got back into the rhythm.“We just make sure we don't trip over him and that he doesn't roll off the stage and we're fine,” says Tony.Their music speaks for itself. They won the first rock gig (特约演奏) they ever entered and it was also only the third gig they had played together as a new band.1. What do we know about the rock band Dionysus?A. It enjoyed global popularity.B. It topped the charts for a year.C. It started Disability Access Week.D. It succeeded without lots of practice.2. What can be inferred about Stephen?A. He lost his legs in a car crash.B. He didn't have great ambitions.C. He was the leader of the rock band.D. He didn't lose hope though being disabled.3. What is the audience's reaction to Stephen's performance?A. They give him high praise.B. They take no notice of him.C. They worry about his health.D. They seem to have forgotten him.4. What is the best title for the text?A. Back into the rhythmB. Dreaming big pays offC. Rock band makes historyD. There's no life without directionCo in solid form, with a temperature of about -78.5℃.Unlike3、Dry ice is 2common ice, dry ice doesn't melt into a liquid . When dry ice melts, it turns intoCo melting into its gaseous a gas. So when you see dry ice "smoking", it's frozen 2state. Dry ice is a popular matter in scientific experiments. It creates projects that look cool.Experiment: Healthy dry ice popsicles（棒冰）This dry ice experiment will catch people's eye, especially little kids' because the dry ice is going to be used to make what the young love to eat. It should take you about 10 minutes or less to have a frozen treat to enjoy.MaterialsOne large block of dry iceA large spoonPopsicle sticksOne cup of your favorite juiceA tall glass filled with waterDirectionsUse the large spoon to make a popsicle-shaped space in a block of dry ice. You can set the ice on a piece of cloth on your table to do this work. Of course, keep in mind that it's okay if it's not exactly popsicle-shaped.Add a popsicle stick to the middle of the space so that when you pour in the liquid, it will freeze around the popsicle stick.Hold the popsicle stick in place and wait a few minutes for your popsicle to harden. After several minutes, take away the popsicle from the block of dry ice and put it into a tall glass of water for a few seconds. Do this to warm up the popsicle just a bit. Otherwise, it will be too cold.1.According to the text, what's the main difference between dry ice and common ice?A. Their forms.B. Their shapes.C. Their temperatures.D. Their states when they melt.2. What's the first step to do the experiment?A. To fill the tall glass with juice.B. To pour the juice into the space.C. To make space in the dry ice for juice.D. To put a stick to the middle of the dry ice.3. How does the dry ice work in the experiment?A. It gives out "smoke".B. It is mixed in the juice.C. It makes the juice freeze.D. It makes the popsicle look cool.4、When Gitanjali Rao shared how she likes “finding solutions to real problems”, it was hard to imagine this dynamic 11-year-old girl could settle a problem that has escaped scientists for years.In just three months, Rao came up with a device(装置)that can replace the costly and lengthy tests currently used to reliably determine lead(铅) levels in our fresh water. Inspired by the current litigation (诉讼)in Flint, Michigan, a caseof water pollution from 2014 to 2015, Rao designed a new testing system that resulted in her being named America’s Top Young Scientist for 2017.Rao had been following the water problem for about two years. She was amazed by the number of people affected by lead pollution in water and wanted to do something to change this. Gitanjali spent months trying to convince local high schools and colleges to give her lab time to continue her experiment. At home, Gitanjali worked on her project in the “science room” she asked her parents to create for her. Rao has created a device that uses three parts: a cartridge, a Bluetooth reader and an app. To put it simply, the cartridge contains carbon nanotubes(纳米管) that react to lead. This reaction is then registered by the Bluetooth reader, which sends a signal to a mobile app that can tell you immediately if your water is safe to drink.Rao appropriately named the device Tethys after the Greek goddess of fresh water, and is hoping to make a little improvement to get the device on the market. While we may not be aware of any lead pollution present in our aging pipelines, lead poisoning can cause delays in physical and mental development. With Rao believing that the “purpose of science is to make a difference”, her incredible invention could make a difference to millions of people in the United States.1.What do we know about Rao’s device?A.It’s cheap and quick.B.It’s cheap and inacc urate.C.It’s expensive and reliable.D.It’s portable and time-consuming.2.What made Rao have the idea of designing the device?A.Her parents’ suggestions.B.The name of the Greek goddess.C.Her interest in settling real problems.D.The water pollution litigation in Flint.3.What do the carbon nanotubes function as?A.Sending immediate signals.B.Recording the reaction results.C.Cetecting the presence of lead.D.Showing the water quality results.4.What does the author think of Rao’s invention?A.It will lead Rao to make a fortune.B.It will help millions of Americans drink safe water.C.It will promote the development of science in America.D.It will soon settle the lead-polluted problem thoroughly.5、根据短文内容，从短文后的选项中选出能填入空白处的最佳选项。
