No matter how 11 the food tastes at a chosen restaurant, one may always wonder, "Is there anything better on the next street?"However, I've found the 12 to this question. When I'm asked to name my favourite place to eat in Suzhou, I will reply 13 , "Song He Lou Restaurant." Why is Song He Lou so special 14 hundreds of restaurants? Well, for me it comes down to a perfect balance of delicious food, pleasant atmosphere (氛围) and a near-perfect location.Before coming to Suzhou, I was 15 by my friends from other cities in China that the food could be too sweet. For the first few months I chose to eat in Sichuan or Hunan style restaurants instead of eating much 16 food. However, after falling in love with the city, I came to realize that the food is so closely 17 with its local culture. 18 I asked a localfriend to recommend the best place to try real local style food. She came up with the 19 of Song He Lou.For a first-time visitor, "Song Shu Gui Yu" and "Xie Fen Tofu" are excellent 20 .

Don't feel surprised at the fact.A special electric fork invented by Japanese researchers could make any dish taste salty.According to Hiromi Nakamura, a Post Doctor Researcher at MeijiUniversity of Japan, the technology can be very useful for people withspecial eating habits. For example, the sick with high blood pressure (高血压) can easily develop a low-salt eating habit and still enjoy delicious food.And with the fork, there's totally no risk of over- salting their food. Luckily,the voltage (电压) is so small that it is safe to use the fork.The idea of adding electricity to food was first shown to public as an experiment at the Computer Human Interaction Conference in Austin, Texas, in 2012. Nakamura and her team connected a wire (导线) to a 9-volt battery (电池) and passed it through a straw (吸管) placed in a cup of sweet lemonade. V olunteers reported that the lemonade tasted not as sweet as it usually was, because the electricity created the taste of salt.Nakamura has improved the technology to be able to make the electricity reach the food through forks and chopsticks. "The metallic part of the fork is one electrode (电极), and the handle is the other," Nakamura explained. "When you take a piece of food with the forkand put it in your mouth, you connect the circuit. When you take the forkout of your mouth, you disconnect the circuit. So it actually works as a switch."Simon Klose, TV presenter of food programme Munchies, who visited Nakamura to try out the fork himself, then said it was one of the greatest eating experiences he'd ever had. ''When I first heard of electric food, it sounded terrible," he said. He later continued to use the fork to eat pieces of fried chicken, and found that the saltiness greatly increased as the electricity was connected.Nakamura has been eating "electric" food for the past three to four years in order to understand it better. "For me," she said," it may seem like we're cooking but we're actually working on the human taste."()21.The electric fork maybe good for people who______.A. need to lose weightB. work as researchersC. show interest in physicsD. have high blood pressure()22.Paragraph4mainly tells us______.A. what creates the taste of saltB. how the electric fork worksC. where the electric fork was inventedD. when the technology was known to public()23.

The idea of adding electricity to food was first shown in a TV programme.()24. Which of the following would be the best title for this passage?A. A Famous ResearcherB. An Interesting ExperimentC. A New InventionD.A Great Eating Experience(B)In our daily life, robots are often found to do work that is too dangerous, boring, difficult or dirty. And we often see kids play with toy robots.But what exactly is a robot? There are some important characteristics that a robot must have. These characteristics might help you decide what is and what is not a robot. It will also help you to decide what you will need to build into a machine before it can be considered as a robot. A robot has these important characteristics.Sensing First of all, your robot would have to be able to sense the environment around it. Give your robot sensors: light sensors (eyes), touch sensors (hands), chemical sensors (nose), hen ring sensors (ears) and taste sensors (tongue).Movement A robot needs to be able to move around its environment. It can move on wheels, walk on legs or be driven by small engines (发动机). A robot can move either the whole body or just parts of it.Energy A robot needs to be able to power itself. Some robots might power itself with sunlight, some might with electricity, while others with the battery. The way your robot gets its energy will depend on what your robot needs to do.Intelligence A robot needs some kind of "smarts". A programmer is the person who gives the robot its "smarts". The robot will have to have a certain way to receive the program so that it knows what it is to do.()25. The underlined word "it" in Paragraph 2 is about ____.A. the toyB. the character is tieC. the machineD. the engine()26. The chemical sensors may help a robot to ____.A. seeB. catchC. hearD. smell()27. In how many ways can a robot power itself according to the passage?A. Two.B. Three.C. Four.D. Five.()28. What is the main purpose of the passage?A. To help people understand what a robot is.B. To tell what a robot can do in our life.C. To describe the movement of a robot.D. To introduce the history of robots.(C)Researchers at China Aerospace Science and Industry Corp, a State-owned defense contractor, have developed and made the world's first robot whale shark (鲸鲨).The robotic shark has been on display in an aquarium (水族馆)at Shanghai Hai chang Ocean Park since January.A whale shark is a slow-moving carpet shark and the largest known living fish.Designed and built by engineers at the Shenyang-based No. 111 Factory, the underwater robot is 4.7 metres long. weighs 350 kilograms and can move 42 metres a minute.Powered by a lithium battery, it can swim, turn, float and dive like a real shark by moving its mechanical fins (鳍). The mouth and gills (鳃) can also open and close like a shark's. The biomimetic shark is made of sensors, multi- joint fins, batteries, and systems which enable it to avoid what's in the way in all directions."The robot can reach a depth of 10 metres and work for as long as 10 hours," said Fang Xuelin, a senior researcher in charge of the robot shark program."The shark can be remotely controlled and can also swim based on preset programs or its own sensors, "he said."We have built multiple kinds of robot fishes… the robotic whale shark is the largest mechanical fish we have made so far," Fang added. "Our robots are to serve three purposes-to perform in aquariums for entertainment, spread knowledge about the sea and aquatic (水生的) animals among youngsters, and carry out scientific tasks such as hydrological surveys, underwater photography and environmental inspection.""The factory now plans to develop more types of aquatic robots, including some extinct mammals (哺乳动物), for display in parks and schools. It will also promote the products to businesses engaged in fields such as underwater salvage and mineral prospecting," he said.()29.The whale shark on display is____.A. the world's first robotB. the largest living fishC. a 7.4-metre-long sharkD. a robotic shark()30.

The limits of the aquatic robots.B. The purposes of the aquatic robots.C. The progress in making aquatic robots.D. The steps to developing aquatic robots.四、信息还原Have you ever dreamed of enjoying the beautiful countryside and listening to u the wind on a cold night? Then you need to go camping. But before you go, you really need to know where tostart. Let's see what USA middle school students do to prepare for a camping trip.33 They often choose lakes, mountains. the forest or the seaside. Camping grounds areall over the USA. When they make their decision, they will tell their parents where they will go.34 If they are going to a remote area, they will take a bag including a pocket knife. a flashlight (手电筒), food and water. A good map and compass are also necessary to take to keep them safe.35 Most tents are easy to put up. They come with a ground sheet, which stops water from getting in, as well as a fly screen, so that bugs don't fly into the tent at night.36 For example, if they want to go hiking, they will take a strong pair of walking boots, some lightweight trousers and a waterproof coat.37 Why not spend it camping with your parents or friends?A. Do you know all the things USA students do when they go camping?B. One of the most important things is a light, brightly-coloured tent.C. They will look for as many friends as they can to go together.D. First of all, they decide where to camp.E. Depending on what kind of activities are, they bring different clothes.F. Safety is the most important thing.G. Summer vacation is right around the corner.五、词汇运用第一节根据下列句子所给汉语注释或首字母,写出空缺处各单词的正确形式。
