However, I can hold on. 我有点累了，但我能坚持下去。 Later, however, he changed his mind. 可是他后来改变了主意。 He said that it was so; he was mistaken, however. 他说情况如此，可是他错了。 辨析：but为口语常用词，语气较强，且转折的意味比however要强，泛指与前述情况相反。从语序上看，but总是位于所引出的分句之首，but之后一般不使用逗号。 e.g.He is young but very experienced. 他虽年轻，但经验很丰富。 It is hot in summer here, but it is not cold in winter. 这里夏天热，但冬天不冷。 She looks very young, but she is already in her 30s. 她看上去很年轻，可是她已经三十多岁了。 5suddenly adv. 忽然，突然 e.g.Suddenly it began to rain.突然天开始下雨了。 Suddenly the baby cried loudly.这个婴儿突然大声哭起来。 The policeman suddenly appeared in the doorway.警察突然出现在门口。 6win v. 获胜，赢 win的过去式和过去分词分别是won，won。 辨析：beat与winwin和beat都可用作及物动词，作“赢、战胜”讲时，其区别主要在于宾语的不同。充当win的宾语的是比赛、战争、奖品、奖项、金钱等名词，即race, match, game, competition, war, prize之类的词。 e.g.They won the match this time.这次比赛他们赢了。 He won first prize in the surfing competition.他在冲浪比赛中获得第一。 充当beat的宾语的则是比赛、竞争的对手，即指人或球队的名词或代词。 e.g. We played very well, and we beat them.我们发挥很好，打败了他们。 We beat the strongest team in the football match this time.在这次足球赛中我们战胜了最强的那个队。 拓展：win的名词形式为winner，意为“胜利者、成功者”。 e.g.He is the winner of this competition.他是这次竞赛的胜利者。 7Da Vinci was born in the countryside.译文达芬奇出生在农村。 be born in意为“出身于”，后面可接时间或地点。e.g.Li Ping was born in 1988. 李平生于1988年。 Tom was born in Hebei Province on February 12, 1999. 1999年2月12日汤姆生于河北省。 注意：be born + in/into/to还可表示“降生到某家庭”。 e.g.He was born in a workers family. 他出生在一个工人家庭。 In 1867 Madam Curie was born into a teachers family. 1867年居里夫人出生在一个教师家庭。 8From an early age, he showed great intelligence and artistic ability.译文从很小的时候，他就表现出极大的智慧和艺术才能。show：作动词（v.），表示“出示，拿给看”。可用于：show sth.“展示某物”，show sb. sth.或show sth. to sb.。e.g.He showed his tickets to the man.他给那人看了一下门票。Will you show me your license？请你出示驾驶证好吗？He showed me where he lived.他指给我看他住的地方。show sb. around/round表示“带领某人参观”。e.g.I shall show you around the Great Wall.我将带你参观长城。 be on show表示“在展览中，陈列着”。e.g.The pictures are on show.这些画正在展出中。 show作名词（n.），译为“秀，展览着”。e.g.flower show 花展car show 车展talk show 脱口秀chat show 访谈节目另外，由show构成的短语：show off 表现，卖弄show up露面show in 领某人进来show interest in 对有兴趣9As he grew older, he learnt to do many different things.译文随着年龄的增长，他学会了做许多事情。 grow vi. 成长，生长，逐渐变得 vt. 种植，栽培 e.g.Nothing can grow without sunlight.没有阳光万物就不能生长。What are you going to be when you grow up？当你长大之后你想成为一个什么样的人？You will grow wiser as you grow older. 随着你年龄的增长，你会变得更聪明。The pollution problem is growing serious. 污染问题日见严峻。His cold is growing worse. 他的感冒正在加重。 We grow flowers and vegetables in the yard. 我们在庭院里种植鲜花和蔬菜。learn v. 学习，得知，获悉 learn to do sth. 学习做某事 e.g.I learned this news from the newspaper. 我从报纸上得知了这个消息。 He is learning to play the piano.他在学钢琴。 Why dont you learn from my mistakes？ 你为何不从我的错误中吸取教训呢？ We learned of/about the public service advertisement on TV.我们从电视上获悉了这个公益广告。 However, we can learn about them from their fossils.然而，我们可以从它们的化石中了解它们。（原文） 9For example, his notebooks include some interesting drawings of flying machines.译文比如，他的笔记本里包括一些有趣的飞行器的绘画。include v. 包含，包括e.g.A good British breakfast always includes sausages.一顿丰盛的英式早餐总会包括香肠。 Your duties include typing letters and answering the telephone.你的职责是打印信件和接电话。 The book includes much useful information.这本书包含了很多有用的信息。 10Some dinosaurs were as small as chickens.
