6、ll you give my kite a lift?” asked my nephew to his sister. Lucy took it up and threw it into the air, but her brother didnt pay attention and ran off, so the kite fell down. “Try again, children,” I said.Lucy once more took up the kite. But John ran off so suddenly that the kite flew out of her han
7、d and it fell flat as before. “Try again,” said I.They did, and with more care, but a side wind came suddenly. As Lucy let go the kite, it was blown against some bushes and the tail was caught. Meanwhile, I went to the kites assistance and set the tail free from the bushes. I told them to find a mor
8、e open area and then try again.We found an open area. I threw the kite up as John ran off. It rose up and promised a high flight. But John was so pleased that he stopped short to look upward. The string became loose. The kite shook and came down to the ground. “I wont try anymore. The kite wont fly.
9、” said he angrily. I replied, “A few disappointments are not supposed to discourage us. And now try again.”And he tried and succeeded, for the kite was carried upward on the breeze as lightly as a feather. He was very excited to enjoy the sight. John began to roll up the string slowly. “Shall we com

Five B .Four C. Three D. Six51. How did John feel when he finally flew the kite up?A. Angry B. Hopeful C.
11、Excited D. Worried52. The writer wants to tell us A. the ways of flying kites B. the pleasure of flying kitesC. the cost of making mistakes D. the importance of keeping trying CTheres a lot of focus on trans fats(反式脂肪) these days. We read about it in the news, and theres talk of passing laws against
12、 trans fats. We are bombarded with the word. Unfortunately, most people dont know that trans fats truly are and why they are so bad for us. A lot of food production companies want to get your dollars by printing “Trans Fat Free” on their label(标签). Sadly, they may not be telling the truth.So what is
13、 a trans fats really? A trans fat is a liquid(液体)fat that is turned into solid. Although there is a very small amount of natural trans fats in meal and dairy products, most of them are created by adding hydrogen to light fat. Food-makers do this because it makes the products last longer on the shelf
14、. Have you ever wondered why cookies can still be crispy and “tasty” after six months to a year on a store shelf? Its because of trans fats. Trans fats are typically found in things like donuts, French fries, cookies, microwave popcorn, and potato chips.Why are trans fats bad for you? Trans fats rai
15、se the bad cholesterol(胆固醇) in your body and lower the good cholesterol that the body needs. Fatty foods do cause overweight. Trans fats build up in the body and block book flow to the heart. People whose diet contains a high percentage of trans fats are at risk of heart disease and stroke.Why can t
16、he food-makers label trans fats free when it isnt? Because of the way the nutrition labeling laws work, the FDA(Food and Drug Administration) has allowed that if a food has less than 0.5 grams per serving (一份) it can be classified as trans fats free. Read the label and you may discover that the pack
17、age actually contains 6 servings, and if you just are three of them, you might have eaten 1.49 grams of trans fats.Besides, in most fast food restaurants, ingredient and nutrition information are not listed. You may be shocked if you know what you are eating. An article in Mens Health magazine point
18、ed that in KFC, hydrogenated(氢化旳) oils appeared 91 times among the ingredients from the menu list. How do you really know if there are trans fats in the food you are eating? One way to truly understand what you are eating is to read the label. Another is to understand your ingredients. Anything on t
19、he label that says hydrogenated or partially hydrogenated, even if the package says “Trans Fats Free”, has trans fats in it. You had better not buy that product. Make a different choice, a choice for your health.53. The expression “are bombarded with” in Paragraph 1 probably means A. are tired of B.

Truths and Facts about Trans FactsC. Buy Trans Fats Free Products Now! D. Dont Eat in Fast Food Restaurant!DThe “halo effect” is a class
22、ic finding social psychology. It is the idea that general evaluations(评价) about a person (e.g. she is likeable) influence judgments about their specific traits(品质)(e.g. she is intelligent). Hollywood stars give the perfect example. Because they are often attractive and likeable, we naturally conside
23、r they are also intelligent, friendly and so on. That is, sometimes, not true.In the 1970s, well-known social psychologist Richard Nisbett set out to prove the fact that we actually pay little attention to our thought processes in general, especially to the halo effect.Nisbett wanted to examine the
24、way students made judgments about teachers. They had been divided into two groups to watch two different videos of the same teacher, who happened to have a strong Indian accent. One group watched the teacher answer a series of questions in an extremely warm and friendly manner. The second group saw
25、exactly the same person answer exactly the same questions in a cold and distant manner. In one the teacher appeared to like teaching and students, and in the other he came across as someone powerful who didnt like teaching at all.After each group of students watched the videos they were asked to eva
26、luate the teacher on physical appearance, mannerisms and even his accent (mannerisms were kept the same across both videos). The same as the hale effect infers, students who saw the “warm” one evaluated him more attractive, his mannerisms more likeable and even his accent as more pleasing. This was
27、unsurprising as it backed up the idea s on the halo effect. At the same time, for those who had seen the other video, the result was just the wrong way around.The surprise is that students had no clue why they gave one teacher higher evaluations. Most said that how much they liked the teacher had no
28、t influenced their evaluation of his individual traits at all.The halo effect is fascinating and now well-known in the business world. For example, books that have “Harvard Classics” written on the front can ask twice the price of the exact same book without it. The same is true in the fashion indus
29、try.So the next time you consider buying a pair of designer jeans or decide whether you like someone, ask yourself whether the halo effect is operating. Are you really evaluating the traits of the person? This simple check could save you wasting your money or refusing a royal friend. Or perhaps, eve
30、n if you do check, youll still never know.56. Why does the author mention Hollywood stars in the first paragraph?A. To help us to evaluate others.B. To explain what the halo effect isC. To show us the background of the storyD. To tell us Hollywood stars are not truly friendly57. Which one do you thi
31、nk is NOT an example of the halo effect?A. You make friends with the people who have good judgmentsB. You prefer to buy the products advertised by a movie starC. You pay more for a simple T-shirt with a famous designers name on it.D. You believe your teachers are intelligent because they appear like
32、able58. What can we learn from the passage?A. People can do nothing to avoid the halo effectB. People use the halo effect widely in the business worldC. People often wonder how the halo effect works before shoppingD. People sometimes dont realize the halo effect when they make judgments59. The passa

I used to sing for my mothers friends. I have written three books of
34、 poems and songs. I gave all the money from the books to childrens charities. Money from the second book was spent on homeless children in Bosnia. I visit patients at a local hospital every Saturday morning. I talk and sing for them. I guess thats whats really fulfilling(令人满意旳)to me when I sing to s
35、omeone who is dying, and someone who is really sick and who doesnt even know whats happening. Everyone can give love, and love is what everyone wants. Thats a really important lesson to me. Making someone happy makes you happy, and they go on and make others happy and its like a chain(链). You change
36、 when you get older, but love is ageless. Love is the same when you are7, 13, or 102years old.A.对现在的生活满意吗?这些问题，也许我们每个人都在不停得问自己，不要被自己对自己的看法所约束，不要自己困住自己，大胆些超越自己，如果从不尝试，就永远不会知道自己其实可以。.楒楒结果，如果对结果不满意就再回头调整一下相应的贴图。（图25）图25高质量的次世代贴图需要符合的几个条件：（图26）图26颜色贴图：应该用很高精度的来源图片制作，不但要高精度，而且还要有丰富的细节，要尽量可以四方连续以达到最高的利用率，
37、贴图的精度必须符合制作上的需要，在选用来源图片时如果精度不够会使贴图的细节达不到要求。高光贴图：高光对强化凹凸贴图和法线贴图的凹凸感有很大的帮助，可以创造出更真实的感觉，通常手绘高光贴图会比直接用Photoshop转的好。法线贴图：这是从贴图上增加细节，而不是直接把高精度的三维模型放在场景中。因此它是很耗资源的，需要有效的利用，它和其它的法线贴图连续融合在一起会更好。次世代的贴图相当强调真实度，它所要营造出来的是一个虚拟的游戏世界，用来构建这个想象世界的元素，需要和真实的世界有一定的关联，美术人员除了要有很好的审美能力之外，还要对这个真实世界的细节有很好的观察力，把有趣的元素和细节表现在贴图上
