选修四预习 Larry Belmont worked for a company that made robots. Recently it had begun experimenting with a household robot. It was going to be tested out by Larry’s wife, Claire. Claire didn’t want the robot in her house, especially as her husband would be away on a business trip for three weeks, but Larry persuaded her that the robot wouldn’t harm her or allow her to be harmed. It would be a bonus. However, when she first saw the robot, she felt alarmed. His name was Tony. He seemed more like a human than a machine. He was tall and handsome with smooth hair and a deep voice, although his facial expression never changed. experiment with…..做实验;试验 test out检验;测试 on a business trip出差 persuade sb. that..说服某人... ※persuade sb.

She felt embarrassed and quickly told him to go. Now she was being looked after by a robot that looked so human, and it was disturbing. One day, Claire mentioned that she didn’t think she was clever. Tony said that she must feel very unhappy to say that. Claire thought it was ridiculous that she was being offered sympathy by a robot, but she gradually admired his wisdom and integrity and began to trust him. He always treated her with dignity. She told him how she was unhappy that her home wasn’t elegant enough for Larry, who wanted to improve his social position with a bigger salary. She wasn’t like Gladys Claffern, one of the richest and most powerful women around. embarrassed adj.尴尬的 ※feel embarrassed感到尴尬 embarrassing adj.令人尴尬的 disturbing adj.令人不安的;烦扰的 ※disturbed adj.心烦意乱的;烦恼的 mention vt.提到，谈到;说起 Don't mention it.没关系。别客气。别提了。 ridiculous adj.愚蠢的;荒谬的;荒唐的 ※It is/was ridiculous that... ……是荒谬的。 look ridiculous 看上去很可笑 offer sb. sympathy 向某人表示同情 integrity n.诚实;正直;完整;完好 ※with integrity 诚实/正直/ 的(地) dignity n.庄重;庄严;尊严 with dignity有尊严的(地) salary n.薪水;薪金 现在进行时的被动语态 形式主语 同位语 As a favor, Tony promised to help Claire make herself more beautiful and her home more elegant. So Claire borrowed some library books for him to read, or rather, scan. She looked at his fingers with wonder as they turned each page. How absurd, she thought. He was just a machine. Tony gave Claire a new hairstyle and improved her makeup. As he was not allowed to accompany her to the shops, he wrote out a list of things that he would need for his work on the house. Claire went downtown and bought these things. She had an appointment to paint her nails, then she went into an expensive clothes shop. as a favour 出于好意 ※do sb. a favour 帮某人个忙 promise to do sth.答应做某事 or rather 更确切地说 with wonder 惊奇地 absurd adj.荒谬的;荒唐的 an absurd idea荒谬的想法 makeup n.妆容 be allowed to do sth. 被允许做某事 accompany sb. to... 陪同某人去某地/某处 write out 写出;誊写 appointment n.预约;约会;委任 have/make an appointment ( to do sth. ) with sb. 与某人有个约会(做某事) nail n.指甲;趾甲;钉子vt.(用钉子)钉牢;固定 The saleswoman there was rude to her, so she rang Tony and told him she was being treated badly. He spoke to the woman, who immediately changed her attitude. Claire thanked Tony, telling him that he was a "dear". As she turned around, there stood Gladys Claffern. How awful to be discovered by her, Claire thought. By the look on her face, Claire knew that Gladys thought they were in a relationship. After all, she knew Claire’s husband’s name was Larry, not Tony. Although it was completely innocent, Claire felt guilty. saleswoman n.女售货员;女推销员 salesman n.售货员;推销员 be rude to sb.对某人粗鲁 be in a relationship在谈恋爱 after all 毕竟,终究;别忘了 above all尤其是;最重要的是 innocent adj.无辜的;清白 的;无罪的 guilty/'grlti/ adj.内疚的;有罪的;有过失的 ※feel guilty 感到内疚 be guilty of 犯有...罪 When Claire got home, she wept. Gladys was everything Claire wished to be. Tony told her she was being sensitive and was just as good as Gladys. He suggested that she invite Gladys and her friends to the house the night before he was to leave and Larry was to return. By that time, Tony expected that the house, which was being completely transformed, would be ready. Tony worked steadily on the improvements. Claire tried to help by working on a light suspended from the ceiling, but she fell off the ladder. Even though Tony had been in the next room, he managed to catch her in time. As he held her, she felt the warmth of his body.

I gave it a last check, and sat myself in the leather seat. I pushed the starting lever on the main panel forwards an inch then immediately backwards again. Looking around, I saw my laboratory exactly as before. Had anything happened? I thought my mind had tricked me. Then I saw the clock.

The laboratory went hazy around me. My niece came in to fetch something, maybe her handkerchief, apparently without seeing me. It probably took her a minute, but to me she moved like a rocket! I pushed the lever further. Night came as if a lamp was being turned out, and in another moment came the day. Tomorrow night came, then skipped to day, again and again, faster and faster still. grip/grip/ vt. & vi.紧握;抓紧 hazy/'heizi/ adj.模糊的;朦胧的;困惑的 ※go hazy 变得模糊 niece/ni:s/ n.侄女;外甥女 ※nephew n.侄子;外甥 fetch/fet∫/ vt.(去)拿来;(去)请来 handkerchief n.手帕;纸巾 复数形式为handkerchiefs 或hand-kerchieves apparently adv.看来;显然 asif 似乎,好像 lamp n.灯:台灯 turn out 关掉;熄灭;在场:使朝外;结果是 again and again 再三，反复 (=over and over again ) 更；愈。修饰形容词或副词的比较级，表示程度 引导方式状语从句 倒装。表时间的介词短语提前，一是强调，二时承前衔接和对比 It is hard to explain the strange and unpleasant feeling of time travelling. It felt like I was being driven fast on a winding road. As my pace grew faster, the walls of the laboratory fell away, and I was left in the open air. The sun and moon looked as if they were being thrown across the sky, but soon there was division between night and day. Around me I saw trees growing like puffs of smoke; they grew, spread, and died in moments. I saw huge buildings rise up, then disappear like in a dream. The whole surface of the earth was being changed, melting and flowing before my eyes. I calculated that I was being pushed through time at hundreds of years a minute. pace n.速度;步伐;节奏 vt.&vi.确定速度;调整节奏 at a (n)...pace 以…速度 keep pace ( with sb./sth.)

I had thought about the risk of stopping the Time Machine many times. So long as I travelled at maximum speed, it didn’t matter. But if I stopped and the same space was being occupied by something else, we would be forced together and explode like a bomb! Like an impatient fool, I pulled the lever backwards hard. With a sudden jolt, the Time Machine was flipped on its side, and I was thrown through the air.   have an urge to do sth. 有强烈的欲望做某事 urge n.强烈的欲望;冲动 vt.催促;力劝;大力推荐 urge sb. to do sth.敦促某人做某事 random adj.随机的;不可思议的 at random随便地;任意地 maximum adj.最大极限的 n.最大量;最大限度 at...speed以……速度 at maximum speed 以最高的速度 explode vi.& vt.爆炸;爆破 ※explode with anger勃然大怒 explode into laughter 突然大笑 jolt n.震动;摇晃;颠簸 vt.&vi.(使)震动;摇晃 be jolted by被……震惊 flip vt. & vi.(使)快速翻转;(用手指)轻抛 定语从句 过去进行时的被动语态 I was stunned for a moment, and then heard the sound of thunder.

I plan to keep this blog to record my experiences and what I learn. I have already done some research on the country. Located to the south of the equator, below many other countries on the globe, it’s often informally referred to as “down under”. I have also read about some iconic sites, such as the Sydney Opera House and the Great Ocean Road, and animals like the cute koalas and kangaroos. I can’t wait to see all of them! However, as I major in social studies, I’m more interested in meeting people in Australia and experiencing their culture, food, and way of life. located adj. 位于 ※be located in/on/at 位于 …be situated in 位于 …lie in 位于… equator n. 赤道 refer to..a...把……称为 .※be referred to as 被称为 Sydney 悉尼(澳大利亚城市) cute adj.可爱的;漂亮的 can't wait to do sth. 迫不及待做某事 major in+专业主修…专业 1 Oct  I’m here in Sydney! Since I arrived, my friend has brought me to my first open-air barbecue and has also shared many different but yummy meals with me, so my first impressions of Australia have been all about food! A lot of typical Australian food, such as the Sunday roast, is originally British. Bakeries, fast-food joints, butcher shops, cafes, and restaurants everywhere provide some of the premier food experiences in the world. The influence of Asian cultures, on the other hand, led to the introduction of bean curd and Asian herbs, along with Australian versions of foods like the Chinese-inspired dim sum. barbecue n. ( abbrBBQ)户外烧烤;烤架 yummy adj. 很好吃的(=delicious） bakery 回包(糕饼)店;面包厂 joint n.公共场所(尤指价格低廉的饮食和娱乐场所);关节 adj.联合的;共同的 butcher /n.肉贩;屠夫;刽子手 premier adj.最著名的;第一的;首要的n.总理;首相on the other hand 另一方面 lead to 导致 herb n.药草;香草;草本 along with与……一起;和 ※along with 连接两个名词或代词作主语时，谓语动词的数应与前面的名词或代词保持一致,类似的还有 as well as, together with, with,besides,except 等。 dim sim ( 特指澳大利亚的)点心 3 Oct  My friend and I have arrived in Katherine, a town in Australia’s Northern Territory. We’re here to learn about the life and customs of the Aborigines, who are native to Australia. The Aboriginal population might be small, but its influence is still visible. For example, “Bondi” in “Bondi Beach” is an Aboriginal word meaning “water breaking over rocks”. To survive in this vast land on the ocean, the Aborigines had to be in close contact with nature. This shows in their music, too, which celebrates the natural world and the spiritual world around them. Most of their musical instruments are really just sticks found on the ground, among which there is an amazing instrument called the didgeridoo. be native to原产于某地;是当地的 ※be home to是……的所在地/出产地 visible adj.看得见的;可见的 Bondi /'bpndar/ Beach 邦迪海滩 (be)in close contact with与……保持密切联系 make contact with与…取得联系 lose contact with 与失去联系 have contact with与有联系 The didgeridoo is made from a tree branch which is hollow. To play the didgeridoo, you put your mouth on one end and blow while vibrating your lips. Unlike a horn, there are no finger holes. The didgeridoo player has to change the shape of his mouth in order to change pitch. A skilled player can play for a long time without stopping to breathe. He does this by continually breathing in through his nose while breathing out through his mouth and into the didgeridoo. I tried to learn how to play it, but after trying for hours, I was convinced that I could never make a musical sound with this instrument! be made from 由…·制成 ※ be made of由……制成 hollow adj. 中空的;空心的 vibrate /var'brert/ vt. & vi.(使)振动 unlike prep.不像;与…不同 horn n.(乐器)号 in order to 为了 pitch n.音高 breathe in 吸气 breathe out 呼气 be convinced that.. 确信. ※ be convinced of sth. 坚化某事 6 Oct It’s almost time for me to say goodbye to Australia. I’ve enjoyed my time here very much. After being here for a while, my biggest impression is the complicated mix of peoples and cultures that make up the nation. Although the main cultural influence since 1788 has been Western culture, minority cultures have also played a part in shaping the unique Australian culture, with many of the new cultural influences contributed by immigrants. It is said that now nearly half of all Australian citizens were either born overseas or have parents who were born overseas. Personally speaking, what I like most about Australia is the people themselves. They have a straightforward and free-and-easy attitude towards life, and their friendliness and warmth made me feel at home wherever I went. After experiencing Australia, I have to say that I agree with the tourism slogan: “There’s nothing like Australia." say goodbye to与……告别 complicated adj.复杂的 make up 组成,构成 ※ be made up of由……组成(构成) minority n.少数民族;少数群体 play a part in在……中起作用/扮演角色 (=play a role in) shape v.决定……的形成;影响……的发展 overseas adv 在国外;在海外 either...or...要么……要么…… (连接两个并列的成分) ※neither...nor...既不……也 personally speaking 就个人而言 straightforward adj.坦率的;简单的 have a (n )..attitude towards/to 对……持……态度 friendliness n.友谊;亲切 feel at home感到自在;有宾至如归的感觉 agree with 同意(某人的观点) slogan /'slougon/ n.标语;口号 Writing THE AMAZING ANIMALS OF AUSTRALIA  Our topic today is “Creatures Unique to Australia", with questions answered by wildlife expert, Dr Jim Smith.  Australia has lots of unique animals, but which animal is a symbol of the country? It has to be the kangaroo, as it has a wide distribution throughout the country. It’s a tough animal that has to survive in a difficult environment. Also, it cannot walk backwards, so it is always moving forwards. This expresses the strength and resolve of the Australians as individuals and as a nation. Baby kangaroos weigh only two grammes at birth. They then find their way into their mother’s pouch—a kind of pocket—to stay safe and warm. They sleep and drink milk in that temporary, protected environment until they are about seven or eight months old. (be)unique to(是)...独有的/特有的 a symbol of……的象征 distribution n.分布;分配;分发 make a distribution = distribute 分发 backwards adv 倒着;向后 resolve n.决心;坚定的信念 at birth 出生时 find one's way into 进入,来到;设法进入 pouch n. 育儿袋;小袋子;荷包 temporary adj.暂时的;短暂的 ※permanent adj.永久的;永恒的 After this phase, they go out to try their legs. After they learn to jump, they gradually spend less time with their mother and learn to be independent. Kangaroos may look cute, but encounters with them don’t always end so well. Kangaroos can hit and kick very hard, so please folks, if you see some kangaroos, remember they’re not for petting! phase n.阶段;时期 independent adj.独立的;自主的 be independent of/from 独立于…… cute adj.可爱的(=lovely) encounter with与…的相遇/邂逅 pet v 抚摸 ※ 属于熟词生义现象 Koalas are cute, and we see so many pictures of people holding them. But in many places in Australia, it is against the law to even touch them. Can you clarify that? They are really quite cute, but the truth is, koalas are very sensitive creatures who can easily panic because of even small changes in their environment. They spend quite a lot of time eating, sleeping, and hanging onto tree trunks, so interaction with humans can cause them a lot of stress. Because of this, the government began to make laws against touching koalas, in the interest of animal protection, as well as public safety. So, if you see one in the wild, you shouldn’t approach it to pick it up or even touch it. If you want to hold a koala, you have to go to certain licensed zoos where animal experts make sure that the koalas selected for each session are in a good state for human contact and that they are handled for only a limited time and on a limited frequency of occasions. against the law 违法 clarify vt. 澄清;阐明 sensitive adj.敏感的;易受影响的;过敏的 ※be sensitive to对……敏感/过敏 spend time doing sth.花费时间做某事 trunk /trank/n.树干 interaction with sb.与某人的互动 cause sb.stress 给某人带来压力 make laws against doing sth. 制定法律禁止做某事 in the interest of为了...的利益 pick up 捡起 licensed adj.得到正式许可的 ※licensev.批准;许可n.(=licence)许可证;执照 session n. 一场;一段时间;会议 in a good state 处于良好的状态 frequency n.发生率;重复率;(声波或电磁波振动的)频率 on.occasions在……的场合下 So, we’ve talked about some cute animals. What about animals which aren’t so cute? favourite is a little creature called the Tasmanian devil. If you are out camping in Tasmania and come across one, the experience might scare you! Tasmanian devils hunt at night, so you won’t usually see them, but you may hear their loud cries when they are fighting or eating. The noise they make could wake the dead. Frightening! They are about the size of small dogs and look like rather large black rats. They also have a terrible smell! Their diet is mostly dead animals. Fortunately, despite their name, they are generally not violent towards people. Tasmanian devil 塔斯马尼亚恶魔;袋獾Tasmania /taZmemio/塔斯马尼亚(澳大利亚州名)田座的 come across=meet with scare v(使)害怕;受惊吓 Жscare sb. into doing sth.恐吓某人做某事 scare...off/away把…吓跑 be scared of(doing)sth.害怕(做)某事 be scared to do sth.害怕做某事 despite prep. 即使,尽管 violent adj.暴力的;猛烈的 ※violence n.暴力;暴行 Australia also has some animals that many people have never heard of, for example, the duck-billed platypus. Is that some kind of bird? Not at all. While it may lay eggs in a nest like a bird, it’s really a primitive mammal, with a unique biology. Its eggs hatch after about ten days, and then the baby platypus nurses from its mother like all other mammals. Its nose looks like a duck’s bill, and it has feet like a duck’s so it can dive under the water, but it’s covered in hair. Do you know what’s really strange about a platypus? The platypus doesn’t use its senses of sight or smell to find food. It has a capacity to find food in the water by using electrical sensors in its bill. There are only a small handful of animals in the world that can do that! duck-billed platypus 鸭嘴兽 lay eggs 产卵 nest n.巢穴;鸟窝;秘密窝点 primitive adi. 原始的,远古的 mammal n.乳动物 biology n.生理;生物学 hatch vi.孵出;破壳以. 使孵出;策划;(尤指)密谋 nurse v吃奶 a sense of sight 视觉 Жa sense ofsmell 嗅觉 capacity n. 能力;容量 Жhave a capacity to do sth.有做某事的能力 a handful of少数人(或物);一把(的量) $
