放假全职准备托福，AmyLee心情很好！本听力材料来自于老托partb，partc，是公认实施有效的听写材料，对于上手托福时间不长的同学非常适合。我曾经一次短时间备考听力提高了7分也归功老托。希望大家和我一样一定要坚持下来噢。相信坚持学习的同学听力上都会有很大的飞跃！
Nopain, no gain.我们的安排是这样的，第一遍用听力软件精听材料（建议做单句听写，听写的时候不要偷看我给的挖空题），然后按照我给的挖空题填关键词，回复后即可看到听力原文和文章精解，我将把难点和易错点oneby one 分析给大家。
回复填空答案格式如下：1____2____3____...et.al.
Before moving on to a new topic, I want to finish up ourunit on______by looking at what may seem a very unusual aspect of_____behavior, a______where the young spiders actually_______the body of their mother. Unlike most other spiders, this species lays one, and only one,______of 40 eggs in her lifetime.The young spiders hatch in mid-spring or early summer, inside a nest of______leaves. Their mother spends the warm summer months bringing home large insects—often 10 times her weight—for meal. The______is always significantly more than her young spiders can eat. So, the mother_____herself up on this extra prey and stores the______in her extra______eggs. As the weather turns colder, there are fewer insect prey to hunt. That's when the nutrients stored in those extra eggs begin to seep into the mother's______.So, when there are no more insects to feed to the young spiders, they attach themselves to the mother's leg______and draw_____by sucking the nutrient-rich blood. After several weeks, the mother is depleted of all nutrients and shedies. But then how do the young get nourishment? They start to feed on one another. Now, if you recall our discussion of Darwin, you'll see the evolutionary value of this: Only the strongest spiders of the clutch will survive this "_______," and the mother spider will have ensured that her genes have an increased chance of survival through future generations.
