I think it is very exciting to go to new places, experience different situations and see new things. Here’s what I have come up with about why my tr avel is so interesting.To start with, whether we know it or not, every day is filled with anxiety about things that we don’t need to worry about in the first place. Going to new places is a good chance to escape from our everyday worries. For example, after a whole day at work, I’m often physically and mentally tired and start to worry about things. However, the moment I get on the train or bus to my next destination (目的地), I forget all my tiredness and worries.Next is one of the most important things in travel: movement.I always take along books to read on my train trips, but in the end, only about five pages or so ever get read, because I just look at things out of the window. Just the ability to move is very enjoyable. Movement also means that we are going to new places and seeing new things. But why is that important? Because experiencing new situations, people and ideas can help us to learn about new things and grow. I have never gone on a trip and come back as the same person; I have always changed and grown through travel.So take every type of trip you can, at every chance you get, and you will not only experience more of the world, but willbecome a happier person with rich experiences.24. The passage is mainly about _____.A. how to have a comfortable lifeB. how to prepare for a tripC. why travel is so excitingD. why some people are tired of travelling25. Why doesn’t the author read much on train trips?A. Because he is too busy working to read.B. Because he is so tired that he can’t read.C. Because he doesn’t like reading on the train.D. Because his attention was taken away by the beautiful view.26. People who travel to new places will _____.①learn new things ②become happier③get more experiences ④have more chances to readA. ①③④B. ①②④C. ②③④D. ①②③27. The author develops the passage mainly by _____.A. giving explanationsB. giving examplesC. making comparisonsD. following the natural time orderCEveryone who has eaten instant noodles knows that it’s very easy to cook them quickly. However, have you ever heard of the danger of eating them?When taking out the noodles from the packaging, you will notice that they are joined together nicely as a piece. Do you know that it needs some form of wax coating (蜡涂层) to makethem joined togethe r nicely? Many people don’t really care much about it because this seems very normal. However, studies have shown that the wax coating is bad for our body.It is advisable to have a break of 2-3 days before we start to eat another packet of instant noodles because our body needs about 3 days to clear that wax coating away. Do you know the danger of having too much wax coating in our stomach? It will lead to CANCER if it is in our body for so long.Luckily, there is a way to reduce the danger before we eat instant noodles. First, wash the noodles with warm water, stir (搅拌) them and pour away the water containing the wax coating. Then repeat the first step and try tostir them again to wash away the wax coating on the noodles before cooking them. The shop vendors (供应商) will often wash away the dangerous wax coating.It is very easy to cook instant noodles but we must pay attention to the wax coating if we eat too much. Imagine having too much of it in your stomach. Oh, my! Hope this article will help more people know about the hidden danger!28. What should you do before eating instant noodles according to the writer?A. Stir the noodles twice in really cold water.B. Stop the noodles from joining together.C. Wash away the wax coating on the noodles.D. Drink large amounts of warm or hot water.29. What’s probably the author’s attitude to eating instant noodles?A. Supportive.B. Careful.C. Happy.D. Angry.30.

The author writes this text mainly to _____ .A. introduce delicious instant noodles to peopleB. tell people the danger of eating wax coatingC. help us to know the good part of wax coatingD. share with us a safer way to eat instant noodlesDAlmost every night for more than 10 years, Kirk Alexander, 48, ordered a late dinner from his local restaurant Domino’s Pizza. But for the past two weeks, he hasn’t called for even once.“A few of my staff mentioned that we hadn’t seen his order in a while. Then I found that it had been 12 days since he last ordered, which is not like him,” Domino’s general manager Sarah Fuller said, feeling she could no longer ignore Kirk’s recent absence.Sarah has known Kirk since 2009, when she started working at the Domino’s Pizza as a deliver driver and often made the short trip to Kirk’s home about six minutes away. She knew Kirk worked from home, and neighbors said he seldom left. She also knew that he had some health problems in the past. Something, Sarah worried, was wrong.Around 1 a.m. on May 8, Sarah sent delivery driver Sean Hamblen to visit Kirk’s home. Sean arrived at Kirk’s home andknocked on the front door several times. There was no answer. He later noticed that the lights and the TV in the home were on. When he called Kirk’s phone, it went straight to voice mail.Sean drove back to the restaurant to tell Sarah and they decided to call 911. Soon, officers arrived at Kirk’s home. So did Sarah and Sean. They heard a man calling for help from inside. Officers broke down the door and found Kirk on the floor in need of medical attention at once after suffering from a heart attack. One day later, they might have been too late.So is keeping an eye on regular customers pa rt of Domino’s business plan? Not really. “Kirk is part of our family here and we feel like we need to do something.” Sarah said.32. Why did Sarah send a delivery driver to visit Kirk?A. Because her staff asked her to do so.B. Because she was worried about Kirk.。

单元综合测评(三)Unit 3The meaningof colourⅠ.阅读理解(共15小题;每小题2分,满分30分)AI have a friend who lives by a three-word philosophy: Seize the moment. Just possibly, she may be the wisest woman on this planet. Too many people put off something that brings them joy just because they haven't thought about it. Don't have it on their schedule, and didn't know it was coming or they are too strict to depart from their routine.I can't count the times I called my sister and said, “How about going to lunch in half an hour?” She would gasp and stammer (结结巴巴地说), “I can't. I have clothes on the line. My hair is dirty. I wish I had known it yesterday, I had a late breakfast, and it looks like rain.” And my personal favorite response: “It's just Monday.” She died a few years ago. We never did have lunch together. From then on, I've tried to be a little more flexible.Life has a way of going faster as we get older. The days get shorter, and the list of promises made to ourselves gets longer. One morning, we are awaken, and all having to show for our lives is repetition of “I'm going to” , “I plan on” and “Someday, when things are settled down a bit.”When anyone calls my “seize the moment”friend, she is open to adventure and available for trips. She keeps an open mind on new ideas. Her enthusiasm for life is contagious. You talk with her for a while, and you're ready to change your attitude to life.My lips have not touched ice cream in 10 years. I love ice cream. The other day, I stopped the car and bought a triple-decker(烘缸). If my car had hit an iceberg on the way home, I would have died happily.Now go on and have a nice day. Do something you WANT to...not something on your SHOULD DO list.【语篇解读】本文作者通过朋友的三字英文哲言——把握现在,告诉我们做自己想做的事,及时享受生活的乐趣。

1. 2017年12月,西成高铁开通。
西安至成都的列车由原来的16小时缩短至4小时左右,票价是飞机的三分之一左右。
航空市场供(S)需(D)相交于E,不考虑其他因素,下列图示能反映这一变化趋势的是A. AB. BC. CD. D【答案】C【解析】根据题目的表述,西成高铁开通后,西安至成都的列车由原来的16小时缩短至4小时左右,票价是飞机的三分之一左右,这会导致西安到成都的飞机的需求的下降,故航空市场的供给相对回落,需求相对会下降,故C图像正确。
其他图像与题意不符。
