⑥公羊不生崽,流放也就无尽期。苏武吹笳大概总是不成腔调,一些断 续的音,夹杂着沉默,像一头受伤的驯鹿,吃力地将一个个长夜拖走。待到 有一天苏武归汉,他会指指胡笳,说它的腔子里存了十九年的昏暗。
⑦从大使混到囚徒,苏武真是个倒霉蛋,但历史上还有比苏武更甚的人, 他就是直接从皇帝沦为阶下囚的宋徽宗。
⑧做了囚徒的人都喜欢仰面看天。天上有鸟,鸟会飞,他若变成鸟就能 重获自由,可是人怎么会飞呢?于是这个囚徒抛弃初心,转变思路,开始在天 空搜寻:他要找一只鸟,这只鸟在中国文化中叫大雁。大雁具有慈悲心,能 为受苦受难的人通风报信。他不想当囚徒,他希望有一支神武的军队将他 劫出牢笼,他要命令大雁为他传送这条求救信息——没错,是命令,这是宋 徽宗最擅长的表达方式。
⑫贝加尔湖在俄罗斯境内,有些旅行者不坐火车而是自驾,一路开到 贝加尔湖,先在湖边买套娃吃烤鱼,然后就想找找苏武当年的痕迹,当然是 没有,一块碑、一个指示牌也没有。不同的文化有不同的关切点,但我们自 己要相信,苏武和他放牧的那群羊,就像天上的一朵云,是从此地出发,飘回 南方,飘进班固的《汉书》,最后变成我们的国民记忆的。
解析 A项,“对于能否生存下去信心不足”错误。苏武无信心的是“要不要告 诉金龟子,你已来到大汉王朝”,而不是“对于能否生存下去信心不足”。B 项,“……不能再当皇帝,只能寄情于书画”错误。结合文中第⑨段可知,宋 徽宗被囚之前,墨渍和颜料已深深嵌入掌纹,再也无法洗净。D项,“还被当 时的史官记载”错误。苏武牧羊是西汉时期的故事,《汉书》是东汉的班 固所作。
⑨时间向前推一推,当现役囚徒还是现役皇帝的时候,他将治理国家放 在末位,而将个人的艺术修养挪到首位,一颠倒,宋徽宗就成了大画家。他 的手和普通画家没什么两样。宫女每天将他的手浸在黄铜盆子里细心剔 刷,他的手却不可救药,墨渍和颜料深深嵌入掌纹,再也无法洗净。这双手, 锁定了这个男人的文化身份。他画过比大雁高贵的仙鹤,那是一幅著名的 画,大片的天空,天空的颜色如同青绿色的湖水,宫殿的屋顶彩云缭绕,彩云 之上是一群仙鹤,每只鹤的姿态都听凭宋徽宗随意摆布。他一直认为自己 可以给鸟类下令,成了囚徒他才明白,宣纸之外的鸟类根本不听他的话。他 每天抬头,日日怅怏,天空寂寞而无情,一只大雁也没有。
2020届高考英语二轮复习系列之疯狂专练二 非谓语动词单句填空+语法填空(word版含答案)
疯狂专练二非谓语动词单句填空+语法填空技巧点拨当句中已有谓语动词又没有并列连词与括号中的动词并列,该动词就是非谓语动词。
此时,就要根据非谓语动词的用法确定用具体的某种形式。
如作主语或宾语,就用动名词(表一般意义)或不定式形式(表具体意义);作目的状语或在形容词后作状语,用不定式;作伴随状语或作定语,要根据与逻辑主语的关系,用现在分词或过去分词;有时也要根据句式搭配来确定,如see/hear/ notice sb.do/doing sth., spend doing sth.等。
具体解题技巧如下:第一步:若句中已有谓语,也不是作并列谓语时,应为非谓语动词。
第二步:根据非谓语动词在句中所作句子成分、句式的特殊要求,或某些词语的特殊要求,确定用哪种非谓语动词形式。
如作目的状语一般用不定式形式,作主语或宾语用ing形式或不定式,在enjoy, finish等动词后作宾语用ing形式,在decide, refuse等动词后作宾语要用不定式形式等等。
第三步:确定非谓语动词与其逻辑主语是主动还是被动关系。

(2018·沈阳市下学期高三第三次模拟考试试题)Wild elephants can tell whether a voice comes from a man,a woman or a boy,a new study says.That's what researchers found when they played recordings of people for elephants in Kenya.Scientists say this is an advanced thinking skill that other animals haven't shown.It lets elephants figure out who is a threat and who isn't.The result shows that the clever animals are also studying people,said study author Karen McComb.“Basically,they have developed this very rich knowledge of the humans that they share their habitat with,” said McComb,a professor at the University of Sussex in England.“Memory is key.They must build up that knowledge somehow.”The study was released on Monday in the Proceedings of the National Academy of Sciences.It's close to but not quite like the Dr.Seuss book,where the elephant Horton hears something that others can't hear.McComb and colleagues went to Amboseli National Park in Kenya,where hundreds of wild elephants live among humans,sometimes coming in conflict over scarce water.The scientists used voice recordings of Maasai men,who on occasion kill elephants,and Kamba men,who are less of a threat to the elephants.As a result,the elephants reacted more defensively—retreating and gathering in a bunch—to the Maasai language recording because it was associated with the more threatening human tribe,said study coauthor Graeme Shannon.They repeated the experiment with recordings of Maasai men and women.Since women almost never spear elephants,the animals reacted less defensively to the women's voices.The same thing happened when they substituted young boys' voices.“Making this kind of fine distinctions in human voice patterns is quite remarkable,” said Emory University animal cognition expert Frans de Waal,who was not part of the study.1.Who were the people taking part in the study?A.Frans de Waal and Karen McComb.B.Dr.Seuss and Graeme Shannon.C.Graeme Shannon and Frans de Waal.D.Karen McComb and Graeme Shannon.2.What can wild elephants benefit from their special ability?A.Identifying and avoiding possible danger.B.Growing much faster than any other animals.C.Having a better understanding of humans.D.Developing their language skills.3.Which can replace the underlined word“substituted”in the last paragraph?A.distinguished B.repeatedC.used D.compared4.What does the passage mainly talk about?A.Wild elephants can distinguish human languages.B.The conflict between humans and wild elephants is growing.C.Wild elephants use language skills to make discrimination.D.Wild elephants can build up good memory and learn tricks.【解题导语】研究表明野生大象能够识别男、女和男孩的声音,它们通过思维区分声音并判断谁能对他们产生威胁。

高考续写关于熊的描述文章及佳句
高考续写关于熊的描述文章及佳句:One fall, my wife Elli and I had a single goal to photograph polar bears. We were staying ata research camp outside" the polar bear capital of the word-the town of Churchill in Manitoba. Canada Taking pictures of polar bears is amazing but also dangerous. Polar bears-like all wild animals-should be photographed from a safe distance. When I'mface to face with a polar bear, I like it to be through a camera with a telephoto lens. But sometimes, that is easier said than done. This was one of those timesAs Elli and I cooked dinner, a young male polar bear who was playing in a nearby lake sniffed, and smelled our spaghetti and garlic bread The hungry bear followed his nose to our camp which was surrounded by a high, wire fence. He clawed, bit, and shoved the wire mesh. He stood onhis hind legs and pushed at the wooden fence posts Terrified. Elli and I tried all the bear defenseactions we knew We yelled at the bear, banged pots and fired blank shotgun shells into the air. Sometimes loud noises like these will scare bears off. Not this polar bear-he just growled and went back to trying to tear down the fence with his massive pawsI radioed the camp manager for help. He told me a helicopter was on its way, but it would be 30 minutes before it arrived. Making the best of thisclose encounter, I snapped some pictures of the bear. Elli and I feared the fence wouldn't last through 30 more minutes of the bears punishment. The camp manager suggested I use pepper spray. The spray burns the bears eyes, but doesn't hurt them So I crept up to our uninvited guest and, through the fence, sprayed him in the face. With an angry roar, the bear ran back to the lake to wash his eyesA few minutes later, the helicopter arrived. As we were lifted into the air: we saw the stubborn bear was already heading back to our camp When Elli and I got home and developed our pictures, we noticed this bear had broken an important tooth. Like humans, polar bears feel pain, have emotions and can be afraid. Elli and I learned our lesson: Beware of a bear with a toothache.关于熊的一篇阅读理解,和这个比较相似The Brown BearMy wife Laura and I were on the beach, with three of our children, taking pictures of shore birds near our home in Alaska when we spotted a bear. The bear was thin and small, moving aimlessly.Just a few minutes later, I heard my daughter shouting, “Dad! The bear is right behind us!” An aggressive bear will usually rush forward to frighten away its enemy but would suddenly stop at the last minute. This one was silent and its ears pinned back—the sign of an animal that is going in for the kill.And it was a cold April day. The bear behaved abnormally, probably because of hunger.I held my camera tripod (三脚架) in both hands to form a barrier as the bear rushed into me. Its huge head was level with my chest and shoulders, and the tripod stuck across its mouth. It bit down and I found myself supporting its weight. I knew I would not be able to hold it for long.Even so, this was a fight I had to win: I was all that stood between the bear and my family, who would stand little chance of running faster than a brown bear.The bear hit at the camera, cutting it off the tripod. I raised my left arm to protect my face; the beast held tightly on the tripod and pressed it into my side. My arm could not move, and I sensed that mybones were going to break.Drawing back my free hand, I struck the bear as hard as I could for five to six times. The bear opened its mouth and I grasped its fur, trying to push it away. I was actually wrestling (扭打) with the bear at this point. Then, as suddenly as it had begun, the fight ended. The bear moved back toward the forest, before returning for another attack—The first time I felt panic.Apparently satisfied that we caused no further threat, the bear moved off, destroying a fence as it went. My arm was injured, but the outcome for us could hardly have been better. I’m proud that my family reminded clear-headed when panic could have led to a very different outcome.1.The brown bear approached the family in order to _______.A. catch shore birdsB. start an attackC. protect the childrenD. set up a barrier for itself2.The bear finally went away after it _______.A. felt safeB. got injuredC. found some foodD. took away the camera3.The writer and his family survived mainly due to their ______.A. prideB. patienceC. calmnessD. cautiousness答案:BAC。

3. affect vt. 影响,侵袭;感动 The change in climate may affect your health. 气候的变化可能影响你的健康。 We were deeply affected by the news of her death. 她死亡的噩耗使我们深为感伤。 用法点拨: affect作及物动词,既有“影响、侵袭”的意思,也可 以表示“感动”,它的名词形式是effect,其结构为:have an effect on对……有影响。 【易混辨析】 affect/effect/influence affect表示“影响;(病)侵袭”,指一时的影响,强调影响的动 作。当其宾语是人时,强调引起心智上或感情上的影响。 effect表示“影响”时,指由于某种原因直接产生的结果。effect也 可用作及动动词,但不表示“影响”,而表示“实现;产生”。 influence多指对人的思想、观念、心理情绪等内在的东西产生潜移 默化的影响,或对人的决定、行为等造成某种程度的影响。

熊大二计划英语学习
熊大二计划英语学习IntroductionThe Big Bear II Plan is a comprehensive and structured approach to English language learning. It is designed to help learners improve their English skills in the areas of speaking, listening, reading, and writing. The plan is divided into three phases, each focusing on specific language skills. The plan is flexible and can be customized to suit the needs and goals of individual learners. The ultimate aim of the Big Bear II Plan is to help learners achieve fluency in English and develop the confidence to communicate effectively in any situation.Phase 1: Building a Strong FoundationThe first phase of the Big Bear II Plan focuses on building a strong foundation in English. This phase is designed for beginners or those who have limited experience with the English language. The key objectives of this phase are to develop basic vocabulary, improve pronunciation, and build confidence in speaking and listening.Vocabulary BuildingOne of the first steps in learning any language is to build a strong vocabulary. In this phase, learners will be introduced to essential English words and phrases that are commonly used in everyday conversation. This will be done through a variety of activities such as reading, listening, and speaking exercises. Learners will also be encouraged to keep a vocabulary journal to track new words and review them regularly.Pronunciation PracticeCorrect pronunciation is essential for effective communication in English. In this phase, learners will practice the pronunciation of English sounds, words, and phrases.

写出二个半反应: Pb –2e- → PbSO 4 PbO 2 +2e- → PbSO 4分析:在酸性环境中,补满其它原子: 应为: 负极:Pb + SO 42- -2e- = PbSO 4正极: PbO 2 + 4H + + SO 42- +2e- = PbSO 4 + 2H 2O注意:当是充电时则是电解,电极反应则为以上电极反应的倒转:为: 阴极:PbSO 4 +2e - = Pb + SO 42- 阳极:PbSO 4 + 2H 2O -2e- = PbO 2 + 4H + + SO 42-7、在解计算题中常用到的恒等:原子恒等、离子恒等、电子恒等、电荷恒等、电量恒等,用到的方法有:质量守恒、差量法、归一法、极限法、关系法、十字交法 和估算法。
(非氧化还原反应:原子守恒、电荷 平衡、物料平衡用得多,氧化还原反应:电子守恒用得多)8、电子层结构相同的离子,核电荷数越多,离子半径越小;9、晶体的熔点:原子晶体 >离子晶体 >分子晶体 中学学到的原子晶体有: Si 、SiC 、SiO 2=和金刚石。
原子晶体的熔点的比较是以原子半径为依据的: 金刚石 > SiC > Si (因为原子半径:Si> C> O ).10、分子晶体的熔、沸点:组成和结构相似的物质,分子量越大熔、沸点越高。
11、胶体的带电:一般说来,金属氢氧化物、金属氧化物的胶体粒子带正电,非金属氧化物、金属硫化物 的胶体粒子带负电。
12、氧化性:MnO 4- >Cl 2 >Br 2 >Fe 3+ >I 2 >S=4(+4价的S) 例: I 2 +SO 2 + H 2O = H 2SO 4 + 2HI13、含有Fe 3+的溶液一般呈酸性。
14、能形成氢键的物质:H 2O 、NH 3 、HF 、CH 3CH 2OH 。
15、氨水(乙醇溶液一样)的密度小于1,浓度越大,密度越小,硫酸的密度大于1,浓度越大,密度越大,98%的浓硫酸的密度为:1.84g/cm3。
16、离子是否共存:(1)是否有沉淀生成、气体放出;(2)是否有弱电解质生成;(3)是否发生氧化还原反应;(4)是否生成络离子[Fe(SCN)2、Fe(SCN)3、Ag(NH 3)+、[Cu(NH 3)4]2+ 等];(5)是否发生双水解。
