AKing’s College Summer School is an annual (年度的) training program for high school students at all levels who want to impro ve their English.

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. What does the underlined word “it” in the last paragraph refer to?A. The instant noodle.B. The hidden danger.C. The attention.D. The wax coating.31. 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.
