●
●
●
Answer Choices
○ Songbird species that are especially vulnerable to predators have evolved ways of reducing the dangers associated with begging calls.
○ Songbird parents focus their feeding effort on the nestlings that beg loudest for food.
○ It is genetically disadvantageous for nestlings to behave as if they are really hungry when they are not really hungry.
○ The begging calls of songbird nestlings provide a good example of overly damaging cost to signalers of signaling.
○ The success with which songbird nestlings communicate their hunger to their parents is dependent on the frequencies of the nestlings' begging calls.
○ Songbird nestlings have evolved several different ways to communicate the intensity of their hunger to their parents.

答案是1, 2, 3  我做题时选了234   
12都是段落首句的改写3是最后一段的总结
4的错因是神马！！！ 难道不是全文第一句话的改写吗

●
●

Answer Choices
1.        Parasitic relationships involve the interplay of aggression by the parasite and resistance and adaptation by the host.
2.        Mutualism ordinarily involves an interaction between two        members of the same species.
3.        Mutualism is unique among symbiotic relationships in that it  r benefits both partners involved in the relationship.
4.        Parasitic damage to Australian rabbits was never reversed because the rabbits were unable to adapt to the parasites' attacks.
5.        The rarity of commensal relationships stems from the difficulty of finding relationships that benefit one species without affecting the other.
6.   The structure of biological communities depends on the types of relationships that exist among the species within.

Their structure depends on a web of diverse connections among organisms.
答案是135  ，我选了156
135刚还是文中提到的三个对象的各自特点
但是第六个选项错的原因是什么呢？  因为它是结论 而不是分论点？

TPO22_第3篇
14、        Directions: An introductory sentence for a brief summary of the passage is provided below. Complete the summary by selecting the THREE answer choices that express the most important ideas in the passage. Some sentences do not belong in the summary because they express ideas that are not presented in the passage or are minor ideas in the passage. This question is worth 2 points.
Studies of the Allende meteorite provided information about the composition of chondritic meteorites and their possible origin.
O         
O         
O         

Answer Choices
O        When Allende entered Earth's atmosphere, it broke into thousands of pieces called chondrites because they look like glassy, black seeds.
O        The mineral content of chondrules suggests that they were probably formed in isolated regions of the nebula that remained much hotter than the rest.
O        Chondrules are tiny, millimeter-sized drops of silicate materials that probably formed when lumps of nebular dust were fused at extremely high temperatures and then quickly cooled.
O        Irregularly shaped inclusions in Allende are composed of minerals that are resistant to melting and are believed to be the earlest minerals to have condensed out of the nebula.
O        The matrix that holds the chondrules and inclusions together in Allende consists mainly of grains of nebular dust that were trapped inside the meteor before they could be melted.
O        Except for being depleted in volatile elements, chondritic meteorites are probably very similar in composition to the matter from which planets were assembled.
答案是2、5、6个选项
求问：第三四个选项错在哪里？ 是不是我哪里没看清楚，它们难道不都是原文句子的改写吗？

TPO17那篇的题顶一下，我也想问！我个人感觉是不是6选项只是文章最后一段提的，篇幅相对于5所占的还是少，于是就选3不选6
