Lots of people find it hard to get up in the morning, and put the blame on the alarm clock. In fact, the key to easy morning wake-up lies in resetting your body clock. 1 Here’s how to make one.
● 2 In order to make a change, you need to decide why it’s important. Do you want to get up in time to have breakfast with your family, get in some exercise, or just be better prepared for your day? Once you are clear about your reasons, tell your family or roommates about the change you want to make.
●Rethink mornings. Now that you know why you want to wake up, consider
re-arranging your morning activities. If you want time to have breakfast with your family, save some time the night before by setting out clothes, shoes, and bags. 3 That’s a quarter-hour more you could be sleeping if you bought a coffee maker with a timer.
●Keep your sleep/ wake schedule on weekends. If you’re tired out by Friday night, sleeping in on Saturday could sound wonderful. But compensating (补偿) on the weekends actually feeds into your sleepiness the following week, a recent study found 4
●Kee p a record and evaluate it weekly. Keep track of your efforts and write down how you feel. After you’ve tried a new method for a week, take a look at your record. 5 If not, take another look at other methods you could try.
A. Get a sleep specialist.
B. Find the night motivation.
C. A better plan for sleep can help.
D. And consider setting a second alarm.
E. If the steps you take are working, keep it up.
F. Stick to your set bedtime and wake-up time, no matter the day.
G.Reconsider the 15 minutes you spend in line at the café to get coffee.

But he became inspired when he tho ught about helping ordinary people exposed to cholera. This was the deadly dise ase of its day. Neither its cause nor its cure was understood. So many thousand s of terrified people died every time there was an outbreak. John Snow wanted t o face the challenge and solve this problem. He knew that cholera would never b e controlled until its cause was found. He became interested in two theories that possibly explained how cholera ki lled people. The first suggested that cholera multiplied in the air. A cloud of dangerous gas floated around until it found its victims. The second suggested that people absorbed this disease into their bodies with their meals. From the stomach the disease quickly attacked the body and soon the affected person die d. John Snow suspected that the second theory was correct but he needed eviden ce. So when another outbreak hit London in 1854, he was ready to begin his enqu iry. As the disease spread quickly through poor neighbourhoods, he began to gat her information. In two particular streets, the cholera outbreak was so severe that more than 500 people died in ten days. He was determined to find out why. First he marked on a map the exact places where all the dead people had liv ed. This gave him a valuable clue about the cause of the disease. Many of the d eaths were near the water pump in Broad Street (especially numbers 16, 37, 38 a nd 40). He also noticed that some houses (such as 20 and 21 Broad Street and 8 and 9 Cambridge Street) had had no deaths. He had not foreseen this, so he made further investigations. He discovered that these people worked in the pub at 7 Cambridge Street. They had been given free beer and so had not drunk the water from the pump. It seemed that the water was to blame. Next, John Snow looked into the source of the water for these two streets. He found that it came from the river polluted by the dirty water from London. H e immediately told the astonished people in Broad Street to remove the handle f rom the pump so that it could not be used. Soon afterwards the disease slowed d own. He had shown that cholera was spread by germs and not in a cloud of gas. In another part of London, he found supporting evidence from two other deat hs that were linked to the Broad Street outbreak. A woman, who had moved away f rom Broad Street, liked the water from the pump so much that she had it deliver ed to her house every day. Both she and her daughter died of cholera after drin king the water. With this extra evidence John Snow was able to announce with ce rtainty that polluted water carried the virus.

普通高中课程标准实验教科书《英语》电子课本 Book 3 Unit 1 Festivals around the world B3U1P1-3 FESTIV ALS AND CELEBRATIONS Ancient Festivals Festivals and celebrations of all kinds are held everywhere. The most ancient festivals would celebrate the end of the cold weather, planting in spring and harvest in autumn. Other celebrations were held when hunters could catch animals. They would starve if food was difficult to find, so they celebrated when they had food. They lit fires and made music because they thought these festivals would bring a year of plenty. Festivals of the Dead Some festivals are held to honour the dead, or satisfy and please the ancestors, who could return either to help or to do harm. In Japan the festival is called Obon, when people should go to clean the graves and light incense in memory of their ancestors. They light lamps and play music because they think that this will lead the ancestors back to earth. In Mexico they have the Day of the Dead in early November. On this important feast day, people might eat food in shape of skulls, and cakes with “bones” on them. They offer food, flowers and gifts to the dead. The festival of Halloween had its origin as an event in memory of the dead. It is now a children’s festival, when they can go to their neighbours’ homes and ask for sweets. They dress up and try to frighten people. If they are not given anything, the children might play a trick. Festivals to Honour People Festivals can be held as an honour to famous people or to the gods. One of these is the Dragon Boat Festival in China, which honours the famous ancient poet, Qu Yuan. Another is Columbus Day in the USA, in memory of the arrival of Christopher Columbus in America. In India there is a national festival on October 2 to honour Mahatma Gandhi, the leader who helped gain India’s independence from Britain. Harvest Festivals Harvest and Thanksgiving festivals can be very happy events. People are grateful because their food is gathered for the winter ,and because a season of agricultural work is over. In European countries it is the custom to decorate churches and town halls with flowers and fruit, and people get together to have meals. Some people might win awards for their animals, flowers, fruits and vegetables, like the biggest watermelon or the most handsome rooster. In China and Japan there are mid-autumn festivals, when people admire the moon and give gift of mooncakes. Spring Festivals The most energetic and important festivals are the ones that look forward to the end of winter and to the coming of spring. At the Spring Festival in China, people eat dumplings, fish and meat, and may give children lucky money in the red paper. There are dragon dances and carnivals, and families celebrate the lunar New Year together. In some Western countries there are very exciting carnivals, which take place forty days before Easter, usually in February. They might include parades, dancing in the streets day and night, loud music and colourful clothing of all kinds. Easter is an important religious and social festival in Christian countries. It celebrates the return of Jesus for Christians and it also celebrates the coming of spring. In Japan, the Cherry Blossom Festival happens a little later. The country is covered with cherry tree flowers so that it looks as though it might be covered with pink snow. People love to get together to eat, drink and have fun with each others. Festivals let us enjoy life, be proud of our customs and forget our daily life for a little while.

人教版生物生物必修二教材课后习题答案
人教版生物生物必修二教材课后习题答案 第1章遗传因子的发现 第1节《孟德尔的豌豆杂交实验（一）》 （一）问题探讨 1. 粉色。因为按照融合遗传的观点，双亲遗传物质在子代体内混合，子代呈现双亲的中介性状，即红色和白色的混合色——粉色。 2. 提示：此问题是开放性问题，目的是引导学生观察、分析身边的生物遗传现象，学生通过对遗传实例的分析，辨析融合遗传观点是否正确。有些学生可能举出的实例是多个遗传因子控制生物性状的现象（如人体的高度等），从而产生诸多疑惑，教师对此可以不做过多的解释。只要引导学生能认真思索，积极探讨，投入学习状态即可。 （二）实验 1. 与每个小组的实验结果相比，全班实验的总结果更接近预期的结果，即彩球组合类型数量比DD ∶Dd ∶dd=1∶2∶1，彩球代表的显性与隐性类型的数值比为3∶1。因为实验个体数量越大，越接近统计规律。 如果孟德尔当时只统计10株豌豆杂交的结果，则很难正确地解释性状分离现象，因为实验统计的样本数目足够多，是孟德尔能够正确分析实验结果的前提条件之一。当对10株豌豆的个体做统计时，会出现较大的误差。 2. 模拟实验的结果与孟德尔的假说是相吻合的。因为甲、乙小桶内的彩球代表孟德尔实验中的雌、雄配子，从两个桶内分别随机抓取一个彩球进行组合，实际上模拟雌、雄配子的随机组合，统计的数量也足够大，出现了3∶1的结果。但证明某一假说还需实验验证。 （三）技能训练 提示：将获得的紫色花连续几代自交，即将每次自交后代的紫色花选育再进行自交，直至自交后代不再出现白色花为止。 （四）旁栏思考题 不会。因为满足孟德尔实验条件之一是雌、雄配子结合机会相等，即任何一个雄配子（或雌配子）与任何一个雌配子（或雄配子）的结合机会相等，这样才能出现3∶1的性状分离比。 （五）练习 基础题。。 3. （1）在F1水稻细胞中含有一个控制合成支链淀粉的遗传因子和一个控制合成直链淀粉的遗传因子。在F1形成配子时，两个遗传因子分离，分别进入不同配子中，含支链淀粉遗传因子的配子合成支链淀粉，遇碘变橙红色；含直链淀粉遗传因子的配子合成直链淀粉，遇碘变蓝黑色，其比例为1∶1。 （2）孟德尔的分离定律。即在F1形成配子时，成对的遗传因子发生分离，分离后的遗传因子分别进入不同的配子中。（3）2。 4. （1）白色；黑色。 （2）性状分离；白毛羊为杂合子，杂合子在自交时会产生性状分离现象。 拓展题 1. （1）将被鉴定的栗色公马与多匹白色母马配种，这样可在一个季节里产生多匹杂交后代。 （2）杂交后代可能有两种结果：一是杂交后代全部为栗色马，此结果说明被鉴定的栗色公马很可能是纯合子；二是杂交后代中既有白色马，又有栗色马，此结果说明被鉴定的栗色公马为杂合子。 2. 提示：选择适宜的实验材料是确保实验成功的条件之一。孟德尔在遗传杂交实验中，曾使用多种植物如豌豆、玉米、山柳菊做杂交实验，其中豌豆的杂交实验最为成功，因此发现了遗传的基本规律。这是因为豌豆具有适于研究杂交实验的特点，例如，豌豆严格自花受粉，在自然状态下是纯种，这样确保了通过杂交实验可以获得真正的杂种；豌豆花大，易于做人工杂交实验；豌豆具有稳定的可以区分的性状，易于区分、统计实验结果。 3. 提示：凯库勒提出苯分子的环状结构、原子核中含有中子和质子的发现过程等，都是通过假
人教版高中英语必修五知识点详解
人教版高中英语必修五知识点详解 Units 1-2 1. doubt doubt是高考中的高频考查词汇。doubt可作动词和名词，是新课标重点词汇。其命题角度为：①作动词时， 若为肯定句，后跟宾语从句,通常用if/whether引导，若为否定句，则通常用that引导。 ②doubt作名词时，通常用于There is no doubt that ...(毫无疑问）结构。2010年高考对doubt的考查还将集中 在其后跟从句时连接词的选择上，也有可能将doubt与其他动词或名词放在一起进行词义辨析。 2. expose expose是新课标要求掌握的单词，应重点掌握它的义项及常见用法，特别是be exposed to 句式，其中to为介词，后跟名词、代词和动名词；同时注意exposed to作后置定语和用于句首作状语的用法。另外，being exposed to结构用动名词形式作主语也是重点和难点，极易考查。 预测2010年命题方向为exposed to 作状语和定语的用法。 3. absorb absorb是新课标重点单词，重点掌握其“吸收（液体，热）；吸收，理解（知识）”的词义及其be absorbed in(全神贯注于……)的用法，易考点为该短语位于句首作状语和作后置定语两点，考生应能掌握be absorbed by(为某事物所吸引)；还应联系be engaged in, be devoted to, be involved in和be lost in等常见重点近义短语。 4. apart from apart from是常见介词短语，意为“除……之外”，考生应熟练掌握近义的词和短语：except, besides, in addition (to), other than, except for, except that, except when等。预测2010年高考会在单项填空题中直接考查或者会出现 在阅读理解题中。 5. available available是新课标重点单词，在近几年高考和各地的模拟考试中出现的频率极高，主要考点为：①词义(可得到的，可用的)。命题形式常为形容词词义辨析，如区分accessible, acceptable, sensible, favourite, average, convenient 等。②用法。be available to意为“可利用的”，be available for意为“使……可以享受某物;使……买得起某物”, 要了解二者的区别。 预测2010年高考命题会以考查词义或者形容词短语作后置定语为命题方向。 6. consist of consist of是近几年高考高频考查短语。①理解其词义“组成，构成”。②考查与其他近义词组的用法异同点。 如be made up of, be composed of, constitute, be formed of 等。考生要特别注意consist of要用主动形式表达， 不用系表结构。预测这一考点将成为2010年高考考查的重点，特别是用consisting of 作后置定语。 7. break down 由break构成的动词短语是历年高考命题的重点。考生必须明确break down的几个常见义项，根据不同的语 境加以判断。break down，break up, break off, break away, break in等，都要求考生熟知它们的常见义项，因为 命题时可能会对该短语直接考查，也可在短文中考查对其意义的理解。 8. only+状语（状语从句）位于句首构成部分倒装 这是考生必须熟练掌握的句式之一，以往的高考题中已多次考查到。倒装句式有多种情况，该句式为日常交 际中较常见的一种。特别提示：only只有强调状语或者状语从句才构成部分倒装，强调主语或宾语不用倒装。 预测该句式是2010年高考命题考查的重点。 重要词汇拓展 Unit 1 Great scientists 1. ____ n. 特征；特性 2. _____ vt.&vi. 结束；推断出→______ n. 结论 3. _____ vt. 打败；战胜；使受挫 4. ______ vt. 参加；出席；照顾；护理→_____ n. 参加；出席；侍从；看护 5. _____ vt. 暴露；揭露；使曝光→_____ n. 暴露；揭穿；揭发 6. _____ vt.& n. 治愈；痊愈→______adj.可治愈的 ______ vt.& n. 控制；支配 8. _____ vt. 吸收；吸引；使专心→______adj. 被吸收的；全神贯注的 9. _____ adj. 严重的；严厉的；剧烈的 characteristic 2. conclude；conclusion 3. defeat 4. attend；attendance 5. expose；exposure 6. cure；curable 7. control 8. absorb；absorbed 9. severe 10. _____ vt. 宣布；通告→______n. 宣布；宣告；通知 11. ______ vt. 命令；指示；教导→_____ adj.有教育意义的；有指导意义的→_____n.指导；指示；指令→_____ n. 教师；讲师；指导员 12. _____ vt.&vi. 捐献；贡献；捐助→______n.贡献；奉献 13. _____ adj. 有创造力的；创造性的；独创的→______n.创造；创作 14. _____ adj. 热情的；热心的→______ n. 热心；热情

人教版生物生物必修二教材课后习题答案 第 1 章遗传因子的发现 第 1 节《孟德尔的豌豆杂交实验（一）》 （一）问题探讨 1. 粉色。因为按照融合遗传的观点，双亲遗传物质在子代体内混合，子代呈现双亲的中介性状，即红色和白色的混合色——粉色。 2. 提示：此问题是开放性问题，目的是引导学生观察、分析身边的生物遗传现象，学生通过对遗传实例 的分析，辨析融合遗传观点是否正确。有些学生可能举出的实例是多个遗传因子控制生物性状的现象（如人体的高度等），从而产生诸多疑惑，教师对此可以不做过多的解释。只要引导学生能认真思索，积极探讨，投入学习状态即可。 （二）实验 1. 与每个小组的实验结果相比，全班实验的总结果更接近预期的结果，即彩球组合类型数量比DD : Dd : dd=1 : 2 : 1，彩球代表的显性与隐性类型的数值比为3：1。因为实验个体数量越大， 越接近统计规律。 如果孟德尔当时只统计10株豌豆杂交的结果，则很难正确地解释性状分离现象，因为实验统计 的样本数目足够多，是孟德尔能够正确分析实验结果的前提条件之一。当对 1 0株豌豆的个体做统计时，会出现较大的误差。 2. 模拟实验的结果与孟德尔的假说是相吻合的。因为甲、乙小桶内的彩球代表孟德尔实验中的雌、雄配子，从两个桶内分别随机抓取一个彩球进行组合，实际上模拟雌、雄配子的随机组合，统计的数量也足够大，出现了3: 1 的结果。但证明某一假说还需实验验证。 （三）技能训练提示：将获得的紫色花连续几代自交，即将每次自交后代的紫色花选育再进行自交，直至自交后代不再出现白色花为止。 （四）旁栏思考题不会。因为满足孟德尔实验条件之一是雌、雄配子结合机会相等，即任何一个雄配子（或雌配子）与任何一个雌配子（或雄配子）的结合机会相等，这样才能出现3: 1 的性状分离比。 （五）练习 基础题 1.B。 2.B。 3. （1）在F1 水稻细胞中含有一个控制合成支链淀粉的遗传因子和一个控制合成直链淀粉的遗传因子。在F1 形成配子时，两个遗传因子分离，分别进入不同配子中，含支链淀粉遗传因子的配子 合成支链淀粉，遇碘变橙红色；含直链淀粉遗传因子的配子合成直链淀粉，遇碘变蓝黑色，其比例 为 1 : 1。
