今天听力难度较大，其中有一篇对话是我们集训刚刚练习并讲解的题目。

这篇对话大概讲的是：

一个学生去图书馆找书，结果因为修楼梯collections room移到楼上了，而且老师说书只能在那里看，不能借阅，周末他又有工作很忙所以没法过去看所以upset，后来老师推荐他看现代版，但是现代版没有插图，而且不能复印，学生不愿意。最后老师说要不你看电子版的吧，版本老点但是有插图，而且只要本校学生在anywhere都能online看，而且看完了还能印几页，学生很开心。

大陆托福真题

阅读主要观点提取

总论点：圈养犀牛有三个困难。

分论点一：犀牛会得不孕症infertility。

分论点二：犀牛会患脚疾。圈养的犀牛长期在比较硬的路面行走，脚会浮肿，并且慢慢变得畸形。

分论点三：犀牛会患脑疾。被圈养的犀牛会患有脑软化疾病，会增加它们的死亡率。

听力主要观点提取

总论点：阅读中所得三个问题现在可以被解决了。

分论点一：患有不孕症的犀牛是因为荷尔蒙失调，研究人员发现是由于圈养犀牛的饮食导致了荷尔蒙失调。所以只需要改通过变它们的饮食，不再吃干草hay，便可以解决这个问题。

分论点二：犀牛患的脚疾可以通过射线检测来预防。通过射线检测可以提前诊断出来，所以能够更早的被成功治愈。

分论点三：科学家也找到了犀牛患脑疾的原因是生育这些犀牛的母亲年龄变大。年龄较大的母犀牛体内会积攒很多毒素，所以会让生育出来的小犀牛患有脚疾。所以，只要动物园的管理人员监管犀牛的交配，只让年轻一些的雌性犀牛生育便可以预防这个问题。

经典满分范文

The reading shows three reasons that ensuring successful rhino reproduction and survival in captivity is difficult. However, the speaker contends that the problems mentioned in reading can be solved. 

First, the writer states that many female rhinos in captivity fail to conceive. But the professor argues that this problem can be solved by changing the diet. In fact, hormone imbalances lead to the infertility and these imbalances are results of the diet. Captive rhinos are usually fed on hay, which is uncommon in the wild. So, adjusting diet might improve the fertility. 

Second, the author demonstrates that some captive rhinos have chronic foot disease because they walk on hard surfaces for a long period. Nevertheless, the professor says that radiographic imaging technology allows scientists to look directly at bones to identify defects and deformities early. As a result, rhinos have more chances to be treated successfully. 

Third, the passage points out that some young rhinos born in captivity suffer from cerebral softening, increasing the mortality. In contrast, the speaker suggesting that this disorder occurred in rhino babies whose mothers were relatively old when they reproduced because older rhino mothers have a larger buildup of certain toxic chemicals in their bodies. Thus, this disease can be prevented as long as the researchers only allow young mothers to get pregnant. (218 words)
