同学们，这周我们重点讲解阅读中句子推断题。所以本周的教学目标是：
1.了解托福句子推断题的做题方法和技巧
2.增加词汇量和对句型的理解
我们先来看一下句子推断题的般出题方式：
1) 在托福的考试中，句子推断题应该也属于比较难得一种类型，它主要考察学生对于阅读材料的理解。我们经常会看到题干中问出现infer, imply, suggest。那这个就是句子推断题的一种典型的出题方式。
2) 推断题的做题方法：
推断题是所以的题里面对文章理解能力要求最高的一种题型，所以在做推断题的时候，我们要对整个段落有所理解，然后找到问题所对应的关键句子。我们说在做题的时候看题干很重要，如果说题干问的非常的细致，那么我们就先看文章再看选项，如果它问的比较的模糊，比如说只问了一个词，从这个词可以说明什么，那就先看选项，先确定我们在文章中要看什么。
得分的根本还是在于会做题。如果能够攻下推断题，势必会在阅读部分的得分上有明显提高。
我们和上次一样，通过一些例题来进行实战演练。以下例题都是从TPO资料里取出，对考试有极强的针对性。
1, Spores light enough to float on the breezes were carried thousands of miles from more ancient lands and deposited at random across the bare mountain flanks. A few of these spores found a toehold on the dark, forbidding rocks and grew and began to work their transformation upon the land. Lichens were probably the first successful flora. These are not single individual plants; each one is a symbiotic combination of an alga and a fungus. The algae capture the Sun's energy by photosynthesis and store it in organic molecules. The fungi absorb moisture and mineral salts from the rocks, passing these on in waste products that nourish algae. It is significant that the earliest living things that built communities on these islands are examples of symbiosis, a phenomenon that depends upon the close cooperation of two or more forms of life and a principle that is very important in island communities.【TPO-9 (3) 2#】
It can be inferred from paragraph 2 that the fungi in lichens benefit from their symbiotic relationship with algae in what way?
A. The algae help the fungi meet some of their energy needs.
B. The algae protect the fungi from the Sun's radiation.
C. The algae provide the fungi with greater space for absorbing water.
D. The fungi produce less waste in the presence of algae.
首先我们来看到题干，问的是fungi in lichens 在和algae的共生关系中能获得什么好处，所以这个问题的重点是什么？是algae 的好处吧，那我们就去原文中找，我们会发现在原文中只说到了algae的一个好处。所以选A。
2 Just as painted designs on Greek pots may seem today to be purely decorative, whereas in fact they were carefully and precisely worked out so that at the time, their meaning was clear, so it is with Chinese pots. To twentieth-century eyes, Chinese pottery may appear merely decorative, yet to the Chinese the form of each object and its adornment had meaning and significance. The dragon represented the emperor, and the phoenix, the empress; the pomegranate indicated fertility, and a pair of fish, happiness; mandarin ducks stood for wedded bliss; the pine tree, peach, and crane are emblems of long life; and fish leaping from waves indicated success in the civil service examinations. Only when European decorative themes were introduced did these meanings become obscured or even lost. 【TPO-10 (1) 11#】
Paragraph 5 suggests which of the following about the decorations on Chinese pottery?
A. They had more importance for aristocrats than for ordinary citizens.
B. Their significance may have remained clear had the Chinese not come under foreign influence.
C. They contain some of the same images that appear on Greek pots
D. Their significance is now as clear to twentieth century observers as it was to the early Chinese.
这道题关于中国陶瓷，我我们看到问题会发现它问的非常的不清楚，所以在这种情况下我们会先看选项，然后再去看原文，最后我们发现答案是B。注意选项B的意思，这里面有个倒装加虚拟，这种状况在题目里面其实比较少见。所以不用太担心这种状况。如果出现这种状况的话，我们用排除法就可以了。
3, So, in another set of experiments, Kramer put identical food boxes around the cage, with food in only one of the boxes. The boxes were stationary, and the one containing food was always at the same point of the compass. However, its position with respect to the surroundings could be changed by revolving either the inner cage containing the birds or the outer walls, which served as the background. As long as the birds could see the Sun, no matter how their surroundings were altered, they went directly to the correct food box. Whether the box appeared in front of the right wall or the left wall, they showed no signs of confusion. On overcast days, however, the birds were disoriented and had trouble locating their food box. 【TPO-11 (2) 7#】
Which of the following can be inferred from paragraph 4 about Kramer s reason for filling one food box and leaving the rest empty?
A. He believed the birds would eat food from only one box.
B. He wanted to see whether the Sun alone controlled the birds' ability to navigate toward the box with food.
C. He thought that if all the boxes contained food, this would distract the birds from following their migratory route.
D. He needed to test whether the birds preferred having the food at any particular point of the compass.
这道题目问的是很具体的，所以我们直接去看按原文，看原文的过程中我们发现这是个实验的背景，那么如果在阅读文章中我们讲到实验的话，一般来讲我们只要注意实验的背景和结果就好了，即为了说明什么和说明了什么。
大家也可以多看一些复习材料中的答案分析部分，学会解题思路，这样才能举一反三，真正自己掌握做题的方法。有问题的话欢迎上课时候交流！
