However, this has not stopped the country from creating great building projects. On September 6, UAE officials announced another great project—Mars Science City. Vast deserts and miles of coastlines provide plenty of better conditions for safe rocket launches (发射). And its position on the Earth makes it especially fit as the movement of the Earth provides an extra push, meaning less fuel is needed to get rockets into orbit(轨道). All these seem to make it possible.The Mars Science City project, designed by Bjarke Ingels Group, or BIG, will provide a model to simulate (模仿) living on the surface of Mars, the red planet. It is part of the UAE’ s Mars 117 Project to lead the global race to land humans on Mars and be the first to build a settlement there. Sheikh Mohammed Bin Rashid, Prime Minister and the ruler of Dubai, says,“The UAE seeks international support to develop technologies that benefit humans, and get prepared for a better future for more generations to come.”Built outside Dubai, the 1.9 million square feet city is expected to cost $115 million. It will consist of several laboratories, similar to the ones imagined for the first Mars settlers. Scientists from around the world will be invited to do research to come up with methods to create food, water and energy, using techniques which can be copiedonto the red planet. The living space, where the researchers can live for up to a year, will simulate the planet’s conditions as much as possible.The research city will also include a museum showing famous space achievements to help educate and inspire children to carry on space exploration and discovery. To discover whether the construction method works on Mars, the museum’s walls will be 3D printed with the sand from the nearby desert. Now, if they would only add some living quarters for the general public to experience life on Mars without leaving Earth, life would be perfect.1.What can we conclude about the United Arab Emirates?A.It is short of fine weather.B.It is a nice place for launching rockets.C.It can provide enough fuel supply.D.It has the greatest scientists in the world.2.What will scientists do in the laboratories?cate visitors on trips to Mars.B.Develop the Mars settlers’ imagination.C.Find ways to produce food, water and energy on Mars.D.Create a climate-controlled environment for future use.3.Why will the museum’s walls be 3D printed?A.To show famous space techniques.B.To make full use of the nearby desert.C.To inspire children to love exploration.D.To test whether the construction method can be used on Mars.4.What’s the best title for the text?A.UAE Is to Build Mars Science CityB.UAE’s Great Exploration of MarsC.UAE Is to Build the First Mars SettlementD.UAE’s Scientific Contribution to HumansⅡ.七选五(2019河北保定一模,★★☆)Should schoolchildren have jobs?Now at school, the last thing you probably want to do is to spend your weekends going to work. There is homework to do and sport to play. 1When I was a teenager I had a Saturday job in a supermarket: stacking(摆放) shelves and working at the checkout.Today in the UK you are allowed to work from the age of 13, and many children do take up part-time jobs. 2Teenagers agree that it teaches valuable lessons about working with adults and also about managing your money. So, that’s no bad thing!Some research has shown that not taking on a Saturday or holiday job could be harmful to a person later on. But despite this, recent statistics have shown that the number of schoolchildren in the UK with a part-time job has fallen by one fifth in the past five years.3 Probably not. Some experts feel that young people feel going out to work will affect their performance at school, and they are under more pressure now to studyhard and get good exam results. However, Geoff Barton, general secretary of the Assoc iation of School and College leaders, told BBC News,“Properly regulated part-time work is a good way of helping young people learn skills that they will need in their working lives.” In reality, it’s all about getting the right balance between doing part-time work and having enough time to study and rest.4 One 13-year-old girl called Rachel, who has a Saturday job in a shop, told the BBC,“I enjoy my job because I’m earning money and it helps increase my confidence in speaking to people and socializing w ith people I work with.” That seems like something worth getting up on a Saturday morning. 5A.Did you do a part-time job when you were at school?B.So you are not free to do what you are feeling like doing.C.It is a waste of time and does no good to your career prospect.D.It’s a taste(尝试) of independence and a useful thing to be put on your CV (简历).E.Does this mean that British teenagers are more afraid of hard work now?F.But your parents probably persuade you to find a job and get some life experience.G.Many young people actually want to work because it gives them a sense of freedom.1. 2. 3. 4. 5.Ⅲ.完形填空(2019福建厦门第二次质检改编,★★☆)I’m sitting at the airport watching people in the last minutes before their loved ones arrive or depart.A woman is running in circles trying to gather family members together for a1.

Ⅰ.阅读理解Tablets (平板电脑) are useful devices, but their big screens always make them as a burden to carry around without a bag. Wouldn't it be great if there were a phone with the powers of a tablet that could be folded up and fit neatly into the hand? Now something like a tablet-shaped but foldable(可折叠的) phone is about to become available. In February, Samsung and Huawei both introduced foldable phones, the Galaxy Fold and Huawei Mate X separately, to the public for the first time. Mobile phone use has enter ed the “foldable future”，The Verge noted.The technology could change our lives in significant ways. These devices, due to their bendable screens, give us the larger screens we want but still fit easily into the pocket. The technology could change other devices too. For example, we could make TVs that stick to walls like posters, or fold up easily to hide away in drawers, which could help increase available space to the maximum. In a keynote address, Justin Denison, Samsung's senior vice president, called the foldable screen “the basis for the smartphone of tomorrow”. “It's a blank canvas (画布) for us to do something beautiful together，” he said.So is there nothing to stand in the way of the foldable future? According to tech news website Android Authority, the necessary displays were difficult to produce. In 2012, nine out of ten foldable screens produced were defective or unusable. Today, that 10 percent rate has been improved to almost 90 percent. However, at present these foldable devices are expensive. For example, the price of Huawei Mate X is 17, 500 RMB. That's a price that few people will be able to afford.But if the foldable device isn't going to change the world overnight, there is no doubt that it is coming. Patrick Moorhead, an industry expert told The Verge, “Few are debating if foldable mobile displays are the future of smartphones; the only question is when and by whom.”本文是一篇说明文。
