历史 ：地图。
P的宇宙观是错的，他是地心说的倡导者，他做出的地图也是错的。过了很久，，他的地图被发现了，然后就越来越权威。哥白尼根据他的地图出海探索，因为距离刚刚好，所以觉得自己到的是亚洲而不是美洲。后来越来越多的人开始航行，然后探索发现了很多东西，地图制作就越来越多。人们逐渐认识到P地图有误，并开始改正。尽管改了很多，但是P的影响有一部分仍在延续。

对于托福阅读，如果在平时能做一些阅读题目，对于很多同学来说都是非常有帮助的，接下来就和出国留学网来看看托福阅读练习题目解析：青蛙的鸣叫声。
青蛙的鸣叫声
一开始引出青蛙的两种发声whine和whine-chuck，然后提问为什么要发出复杂的whine-chuck声？解释原因，whine-chuck声更能吸引雌性，并且通过试验放磁带的方法证明了该解释；既然whine-chuck声更能吸引雌蛙，为什么雄蛙不总是发出这种声音？原因一可能是whine-chuck叫声会耗费更多能量，但研究发现并不多耗能；原因二可能是whine-chuck叫声更容易被捕猎者蝙蝠听到；之后通过播放录音证实whine-chuck叫声确实更能吸引捕猎者；之后又提问既然whine-chuck叫声又能吸引雌蛙又能吸引捕猎者，那什么决定着雄蛙什么时候发出whine叫声，什么时候发出whine-chuck叫声？解释：取决于雄蛙所处的群体大小，当雄蛙处于大群体时，个体被捕杀的概率减小，但个体对雌蛙的吸引竞争加剧，所以此时雄蛙发出whine-chuck叫声；反之，当雄蛙处于小群体，个体被捕杀的概率增大，而彼此竞争减小，所以此时只发出whine叫声。

托福阅读关于疾病的练习题
【Introduction】
加拿大一项新研究发现，患二型糖尿病的病人，若能同时做有氧及重量训练运动，将可显着地降低血糖。
【Section One】Article
It‘s no secret that exercise is key to controlling type 2 diabetes — and many doctors already urge their diabetic patients to get active. But it‘s a vague directive: How much exercise is enough? How often? And what kind? The simple answer is that any is better than none — in sum, that‘s what a new study published in the Sept. 18 issue of the journal Annals of Internal Medicine found. But it also found that not all exercise is created equal and that the combination of aerobic exercise and weight training is significantly better for controlling blood sugar than either alone.
The elegantly designed study, led by researchers at the University of Calgary and the University of Ottawa, involved 251 patients aged 39 to 70, with type 2 diabetes. The patients, none of whom were regular exercisers, were randomized to one of four groups: aerobic exercise, resistance training, a combination of both, or none. For 22 weeks, the aerobic group worked out for 45 minutes three times a week on the treadmill or stationary bicycle; the resistance-training group spent an equal amount of time on weight machines. The combination group was at the gym twice as long as th...
