课时跟踪练(一) Warm-up & Lesson 1 Pre-reading.阅读理解AZipped (用拉链拉上或扣上) into a bag, it looks like a large umbrella.Unfolded, it goes along the street like any other bicycle.Its the “Abike”， the brainchild (脑力劳动的产物) of British inventor Sir Clive Sinclair, who made history in the 1970s by developing the worlds first pocket calculator.He described his new invention as “the worlds smallest, lightest foldable bicycle” “My original thought was that if you could have a bicycle that was dramatically lighter and more firm than the ones that exist today, it would change the way in which bicycles are used，” said Sinclair.The minibike, showed in Singapore last week and set to go on sale worldwide at a price of nearly $300, is built for riders as heavy as 112 kilograms and is heightadjustable (可调整高度的). It takes about 20 seconds to fold or unfold. Its wheels are a quarter the size of those on a regular bicycle, but Sinclair promises a smooth ride for most cyclists.“You require no extra energy to ride the Abike and it can go up to 15 miles per hour (24 kilometres per hour)，” he said. Constructed mainly of plastic, the 5.5kilogram bicycle folds into a package of less than 0.03 cubic metres. Sinclair also invented the first pocket TV in 1984 and the futuristic C5 electric tricycle in 1985. He said he hoped the bicycle would attract common citizens, officials, campers or anyone needing transport for a short trip and he said the next step for the “Abike” was to add an electric motor in a few years.语篇解读：普通的自行车人人都见过，可是你见过折叠以后像伞一样的自行车吗？现在有人发明了这种自行车。1The most important character of this kind of bicycle is its_.

Afour times Bthree times Conefourth Donethird解析：选A细节理解题。由第五段开头可知，传统自行车车轮大小是这种新型自行车车轮的四倍。3Which would be the best title of the passage?AWorlds Smallest Foldable Bicycle ArrivingBA New Bicycle, a Large UmbrellaCA Foldable Bicycle, a Large BagDA Great Inventor of a New Bicycle解析：选A标题归纳题。本文自始至终都在介绍一种即将上市的新型折叠式自行车的与众不同之处。因此以A项为题目既高度概括又醒目。4Whats the meaning of the underlined word in Paragraph 5? AAttracted. BContained. CInvented. DMade.解析：选D词义猜测题。根据本句中的mainly of plastic可知，此处是对自行车的制造材料进行介绍。attract“吸引”；contain“包含”；invent“发明”；make“制造”。BDriving a car is not just handling controls and judging speed and distance.It requires you to predict what other road users will do and get ready to react to something unexpected.When alcohol is consumed, it enters your bloodstream and acts as a depressant (抑制药), damaging eyesight, judgement and coordination (协调), slowing down reaction time and greatly increasing the risk of accidents. Even below the drink driving limit, driving will be affected.Alcohol may take a few minutes to be absorbed into the bloodstream and start action on the brain.Absorption rate is increased when drinking on an empty stomach or when consuming drinks mixed with fruit juice.To get rid of alcohol from the body is a very slow process and it is not possible to speed it up with any measures like taking a shower or having a cup of tea or coffee.The present Road Traffic Ordinance states clearly that the limit of alcohol concentration is: 50 milligrams of alcohol per 100ml of blood; or22 micrograms of alcohol per 100ml of breath; or67 milligrams of alcohol per 100ml of urine (尿液)Drivers who cause traffic accidents, or who commit a moving traffic offence or are being suspected of drink driving will be tested.Any driver found drinking beyond the limit will be charged.The driver declared guilty may be fined a maximum of HK $25, 000 and be sentenced to up to 3 years in prison and punished for 10 drivingoffence points; or temporarily banned from driving.The same punishment applies to failing to provide specimens (样本) for breath, blood or urine tests without good excuse.Drink driving is a criminal offence.Be a responsible driver, think before you drink.For the safety of yourself and other road users, never drive after consuming alcohol.语篇解读：酒后驾车是一种危险的行为，会对他人、对自己造成巨大的威胁，所以酒后驾车会受到处罚。因此司机应该对自己、对他人负责，切勿酒后驾车。5The first paragraph is mainly about_.Athe introduction of driving skillsBthe damage of drinking to your bodyCthe effect of drinking on drivingDthe process of alcohol being absorbed解析：选C段落大意题。本文第一段主要介绍的是饮酒后，酒精会进入我们的血液，影响我们的视力、判断力和协调能力，减缓我们的反应速度，增加我们出事故的风险，所以选C“饮酒对驾车的影响”。6The underlined word “it” in the second paragraph refers to “_”Aalcohol BabsorptionCblood Dprocess解析：选D代词指代题。画线词所在句表示将酒精从血液中清除是一个缓慢的过程，接着说的是采取如洗澡、喝茶或者咖啡的途径来加速这一过程是不可能的，所以“it”在这里指代的是将酒精排出体外的“过程”，故选D。7Which of the following is TRUE according to the pas
