I think performing onstage is the only way I can become more popular at school. But I have stage fright (怯场). I get so nervous every time I get onstage, even if I’m just talking about the simplest things. My nervousness destroys my hope. I feel like I will never be popular at school. What should I do?Miracle Dear Miracle,Firstly, it is natural to feel nervous onstage. My suggestion would be to do a calming activity, such as drinking tea, taking a deep breath, listening to some light music or meditating (冥想), before you perform.However, I have to wonder if performing is the only way for you to become more popular. Perhaps you can do something else to impress (使……印象深刻) your classmates. Everyone is good at something.But finally, I also wonder if you really need to be more popular in the first place. Do you have at least a few close friends? Are your studies going well? Are you healthy? If so, maybe you don’t need to care so much about being popular. Not everyone is going to like you all the time. But as long as you have a few close friends and a family to support you, you won’t need all those other people.Mike 38.Why does Miracle feel worried?A.She cannot get on well with others.B.She is too popular at school.C.She has trouble talking onstage.D.She has difficulty with her schoolwork. 39.What does the underlined word “destroy” in the first letter?A.偷窃B.顶替C.忽略D.摧毁40.What advice does Mike give to Miracle?A.She can listen to some rock music to cheer herself up before performing.B.She doesn’t need to be popular if she has some close friends and a family to support her. C.She can ask others to drink tea together if she wants to calm down.D.She has to try her best in order to be liked by everyone in her school.四、补全对话7选5从A-G中选出正确答案,其中有两个多余选项A: Christmas used to be my favorite time of year, but right now I feel terrible.B: Yes. Jack.____41____ A change of situation would easily affect(影响)people’s feelings. A: What do you miss most as Christmas is coming, David?B: Of course, my family. ___42___A: Me, too. Nothing in the world is better than being with my family at Christmas time.B: At least, your brother is here with youA: That's true. ____43____But now, instead I do feel great to have him around on this special day here.B: Maybe he'll be here soon.

A Chinese teenage photographer has made this dream come true.With his work Weed (野草) on the Wall, Gong Zijie, a 14-year-old boy from Changsha, Hunan, won the 2014 International Photography Competition for Kids in China. It was hosted by National Geographic Kids. Gong got the first place for the subject Wild Vacation. His photo shows the shadow of a weed on the Forbidden City's red walls. In photographer Li Shaobai's words, "The picture is silent but powerful."Gong learned photography from his father, a professional photographer working for Hunan TV. Since the age of 4, he has been following his father to take pictures of nature and society.Gong is a patient photographer. When he finds something amazing, he can spend hours waiting for the perfect time to catch the moment. In his first work, Gong took the beautiful view of the sunset near his hometown: It looked simple, but Gong worked for four days to take the best photo.Now, the young photographer cares more about social (社会的) problems. In Gong's pictures of Liuyang River, hundreds of dead fish show us the deadly results of pollution. He has made up his mind to document polluted rivers at least once every year to make people pay more attention to environmental protection."Now photography is not only a hobby, but also a duty(责任) for me." said Gong. 46.Where is Gong Zijie from?____________________47.What does photographer Li Shaobai think of Gong's work?____________________48.Did Go learn photography by himself?____________________49.When did Gong begin to learn to take photos?____________________50.Why did Gong decide to document polluted rivers?____________________六、改写句子51.You have to stay at home on weekends.

人们食入并吸收这种毒素后,神经系统的功能将遭到破坏。

该毒素由两条肽链组成。

下图为肉毒毒素的局部结构简式,据此判断下列说法不正确的是()A.由图示结构可知,肉毒毒素的单体是氨基酸B.该局部结构由5种单体组成,含4个肽键C.一分子肉毒毒素至少含有1个氨基和1个羧基D.组成肉毒毒素的元素一定只有C、H、O、N2.{若“淀粉→麦芽糖→葡萄糖→糖原”表示某生物体内糖类的某些转化过程,则下列说法不正确的是()A.此生物一定是植物,因为它含有淀粉和麦芽糖B.上述关于糖的转化不可能发生在同一生物体内,因为淀粉和麦芽糖是植物特有的糖,而糖原是动物特有的糖C.此生物是动物,因为其能将淀粉转化为糖原D.淀粉和糖原都是储存能量的多糖,麦芽糖是二糖3.{下列有关生命系统的结构层次的叙述,错误的是()A.单细胞生物的生命系统中只有细胞这一层次B.一棵白杨树的生命系统层次有细胞、组织、器官、个体、种群、群落、生态系统和生物圈C.H7N9型禽流感病毒属于生命系统中的结构层次D.生命系统的结构层次中含有非生物成分4.{下面关于蛋白质分子结构与功能的叙述,正确的是()A.不同蛋白质含有的氨基酸数量不尽相同B.组成蛋白质的氨基酸可按不同的排列顺序脱水缩合C.组成蛋白质的氨基酸之间可按不同的方式脱水缩合D.有些结构不同的蛋白质具有相似的功能5.{下列有关叙述正确..的是()A.一切生物的生命活动都是在细胞内或在细胞参与下完成的B.人体的每个细胞都能单独完成各种生命活动C.多细胞生物依赖各种分化的细胞密切合作,共同完成一系列复杂的生命活动D.烟草花叶病毒不具有细胞结构,所以它的生命活动与细胞无关6.{如图表示某种蛋白质中相关基团或氨基酸的数目,下列相关叙述正确的是()A.该蛋白质中含有三条肽链B.该蛋白质中共有126个肽键C.该蛋白质的R基上共含15个氨基D.形成该蛋白质时共脱掉124个水分子7.{如图表示有关生物大分子的简要概念图,下列叙述不正确的是()A.若b为葡萄糖,则c在动物细胞中可能为乳糖B.若c为RNA,则b为核糖核苷酸,a为C、H、O、NC.若c具有信息传递、运输、催化等功能,则b为氨基酸D.若b为脱氧核苷酸,则c只存在于线粒体、叶绿体、细胞核中8.{如图是按顺时针方向表示的四种植物细胞的细胞周期,其中说法正确的是()A.图甲的b→a段与图丙的b→a段所用的时间可能一样长B.温度对丙植物a→b段的生理活动有影响C.在a→b段,DNA的复制使染色体数目增加一倍D.观察植物细胞有丝分裂的实验材料最好是选甲植物9.{如图是新鲜绿叶的四种光合色素在滤纸条上的分离的情况,以下说法正确的是()A.色素丁在滤纸条上扩散速度最快B.四种色素都能溶解在层析液中,乙色素的溶解度最大C.在开花季节采下水稻的新鲜叶片做实验,其结果与图中结果相似D.研磨时未加CaCO3,滤纸条上四种色素可能都不出现10.{细胞内生物膜为细胞生命活动提供了广阔场所,不同细胞器增大膜面积的方式可能不同。
