Shyness can be an unhappy feeling. But the good news is, you're not alone. Scientists say that more than 40 percent of teenagers and adults consider themselves shy. Shyness is feeling a little nervous or as if you want to hide when you're around other people or in a new situation.
Scientists say such things as genetics( 进传基因) life experiences, and environment can influence whether a person is shy. For example, in some families, everybody seems to be shy.
What happens if you are shy? Well, being shy may cause you to avoid or miss chances
How do people overcome(克服) shyness? This is what Gilbert tells us:”When I started off trying to get over being shy. I decided to do little steps at a time,including practicing smiling and saying hi to people. And it wo rked for me.”
But shyness is not the kind of thing that most people can get over overnight. Overcoming shyness take time and needs practice.
Here are some tips given by scientists.
Think of what to talk about before you leave home. Prepare things to talk about before you're in a social situation. For example, if you know your classmates are interested in an upcoming event, learn about it so you can join in the conversations.
Let people know you're shy. If you’re shy, just show it. Instead of letting people guess, tell them the truth. Explain that you are shy and feel nervous but enjoy talking to people.
Make things easy for the other person. Remember you're not the only shy person around. Do what you think might help others feel good, for example, say hello or smile.
Pick one social skill to practice at a time Start simply. For example, smile or be the first person to say hi. Choose skills you feel comfortable enough with to practice for a day, a week, a month, or even a year.
75.Which of the following can be put in the blank in Paragraph2 ?

But in the end, she gave up. And what she didn't know at the moment she gave up was that the opposite bank was only 1 mile away.

读下面短文,并用英语回答问题(请注意每小题后面的词数要求,)
E
Do you ever wish you were as thin as a model(模特)or as strong as your favourite football player? Maybe you wish you were taller or just thinner a little. Those thoughts are a natural part of growing up.
But learning what you can and can't change about your body is part of growing up, too. It can be hard to do. But when people accept the way they look, they often feel happier.
Some children worry that they're not growing and developing as fast as their friends. It's important to know that puberty( 青春期) doesn’t happen at the same time for every child. And there are no special medicines that can make it happen sooner!
Eating healthy food and exercising more can make all children feel better. Why? Because they will help you feel energetic(精力充沛的) and keep your body working just the way it should be.
Watching TV and playing computer games can be fun, but they don't do much for your body because you sit when you do them. But when you move your body -- by playing, dancing, taking part in sports, or even cleaning your room--you exercise your muscles( 肌肉). When you exercise the muscle, it gets stronger. And when you have strong muscles you can do whatever you want to do.
88.When do people often feel happier about their bodies according to the passage(答题不超过10 词)
89.What can make all children feel better?(答题不相过10 词)
90.How does your muscle become when you exercise it?(不超过5 词)

Dear Dave，
I know you are interested in Chinese culture and I’m glad you are planning a trip to China. Why not come to Anhui, my hometown, to have some fun.
Anhui Province lies in the east of China. The best time to come here is in autumn, because it’s really cool and you can just take some light coats. There are many famous places to see. For example, Mt. Huangshan, where you will see wonderful plants and special rocks. Besides, Anhui is also famous for ancient villages such as Xidi, Hongcun and so on. As a fan of Chinese culture, don’t forget to try green tea in Anhui which smells good and tastes better. What’s more, come and watch Huangmei Opera. It’s easy to understand and won’t let you down!
Welcome to Anhui! I’m looking forward to seeing you here!
Yours,
Li Hua

One of his friends had stopped to make a bicycle repair, but they had encouraged Mac to carry on, and they would catch up with him soon. As Mac pedaled (骑行) along alone, he thought fondly of his wife and two young daughters at home. He hoped to show them this beautiful place someday. Then Mac heard quick and loud breathing behind him. “Man, that’s a big dog!” he thought. But when he looked to the side, he saw instantly that it wasn’t a dog at all, but a wolf, quickly catching up with him. Mac’s heart jumped. He found out his can of bear spray. With one hand on the bars, he fired the spray at the wolf. A bright red cloud enveloped the animal, and to Mac’s relief, it fell back, shaking its head. But a minut e later, it was by his side again. Then it attacked the back of Mac’s bike, tearing open his tent bag. He fired at the wolf a second time, and again, it fell back only to quickly restart the chase（追赶）. Mac was pedaling hard now. He waved and yelled at passing cars but was careful not to slow down. He saw a steep uphill climb before him. He knew that once he hit the hill, he’d be easy caught up and the wolf’s teeth would be tearing into his flesh. At this moment, Paul and Becky were driving their car on their way to Alaska. They didn’t think much of it when they saw two cyclists repairing their bike on the side of the road. A bit later, they spotted what they, too, assumed was a dog running alongside a man on a bike. As they got closer, they realized that the dog was a wolf. Mac heard a large vehicle behind him. He pulled in front of it as the wolf was catching up fast, just a dozen yards away now. 注意： 1. 所续写短文的词数应为150左右； 2. 应使用5个以上短文中标有下划线的关键词语； 3. 续写部分分为两段，每段开头语已为你写好； 4. 续写完成后，请用下划线标出你所使用的关键词语。 Paragraph 1： The car abruptly stopped in front of him,… Paragraph 2： A few minutes later, the other two cyclists 2018年安徽省合肥市第一中学冲刺高考最后1卷 理科数学试卷 第Ⅰ卷（共60分） 一、选择题：本大题共12个小题,每小题5分,共60分.在每小题给出的四个选项中，只有一项是符合题目要求的. 1. 已知集合{||3|2},{|43}A x x x B x x =-<=-<<，则()R C A B ?=（ ） A ．(4,1]- B ．[3,3)- C ．[3,1]- D ．(4,3)- 2. 已知i 是虚数单位，若2z i =+，则 z z 的虚部是（ ） A ．45i B ．45 C ．45i - D ．45- 3. 已知0w >，函数()cos()3f x wx π=+在(,)32 ππ 上单调递增，则w 的取值范围是（ ） A ．210(,)33 B ．210[,]33 C ．10[2,]3 D ．5[2,]3 4. 《九章算术》之后，人们学会了用等差数列的知识来解决问题，《张丘建算经》卷上有叙述为：“今有女善织，日益功疾（注：从第2天开始，每天比前一天多织相同量的布），如图是源于其思想的一个程序框图，如果输出的S 是60，则输入的x 是（ ） A ．4 B ．3 C. 2 D ．1 5. 已知,αβ分别满足24,(ln 2)e e e ααββ?=-=，则αβ的值为（ ） A ．e B ．2e C. 3e D ．4e 6. 某空间凸多面体的三视图如图所示，其中俯视图和侧（左）视图中的正方形的边长为1，正（主） 视图和俯视图中的三角形均为等腰直角三角形，则该几何体的表面积为（ ） A ．22 + B ．722+ C. 2+．2+7.
