下面是错误答案，用来干扰机器的。
参考答案：A解析：由图知，甲地该月份位于赤道低气压带和南半球副热带高气压带之间，吹东南风。
已知A为烃, B为烃的含氧衍生物. 由等物质的量的 A 和 B 组成的混合物 0.05 mol 在0.125 mol 的氧气中恰好完全燃烧, 生成 0.1 mol 的 CO2和 0.1 mol H2O, 试通过计算回答下列问题:
（1）从分子式的角度看, 等物质的量A和B组成的混合物平均组成可用化学式表示为_________。
（2）另取一定量的A和B完全燃烧, 将其以任意物质的量比混合, 且物质的量之和一定，则：
①若耗氧量一定，则A和B的分子式分别为：
A ； B 。
②若生成的CO2和H2O的物质的量一定，则A和B的分子式为：
A ； B 。

Car sharing is another way to drive green that's gaining in popularity, especially in urban areas. People who
may not drive every day but still want a car to run errands (差事) or drive on weekends benefit most from car
sharing. Car sharing is usually run by a service like Zipcar, though there are non-profit (非营利的) and
informal car sharing services. Members pay a monthly fee and have access to an entire fleet of cars when they
need one. The cars are parked in fixed spots around the city, so members only need to make a reservation, and
then go to the pickup spot.
Car sharing has major environmental benefits because it reduces the number of cars on the road. Members
don't drive just because they are in a car. They plan trips, and if they don't need a car, they don't use one. Still,
a car is available to them if they need to make a big trip to the grocery store, pick someone up at the airport or
if they want to go to the beach for the day. Members also benefit by having access to a car without any of the
headaches of ownership. They usually don't have to pay for the gas, insurance or maintenance (保养), and the
monthly membership fee is less than a typical car payment. So if you really want to go green but aren't ready to
totally give up a car yet, car sharing may be the way to go.
If you still need to get around, but want to go even greener than sharing a car, share a bus!

On Thursday afternoon Mrs. Clarke, dressed for going out, took her handbag with her money and her key in it, pulled the door behind her to lock it and went to the Over 60s Club. She always went there on Thursdays. It was a nice outing for an old woman who lived alone.
At six o’clock she came home, let herself in and at once smelt cigarette smoke. Cigarette smoke in her house? How? Had someone got in? She checked the back door and the windows. All were locked or fastened, as usual. There was no sign of forced entry.
Over a cup of tea she wondered whether someone might have a key that fitted her front door—“a master key ”perhaps. So she stayed at home the following Thursday. Nothing happened. Was anyone watching her movements? On the Thursday after that she went out at her usual time, dressed as usual, but she didn’t go to the club. Instead she took a short cut home again, letting herself in through her garden and the back door. She settled down to wait.
It was just after four o’clock when the front door bell rang. Mrs. Clarke was making a cup of tea at the time. The bell rang again, and then she heard her letter box being pushed open. With the kettle of boiling water in her hand, she moved quietly toward the front door. A long piece of wire appeared through the letter box, and then a hand. The wire turned and caught around the knob on the door lock. Mrs. Clarke raised the kettle and poured the water over the hand. There was a shout outside, and the skin seemed to drop off the fingers like a glove. The wire fell to the floor, the hand was pulled back, and Mrs. Clarke heard the sound of running feet.
