问题好多= = 先把阅读文章和题目贴上来：
exercise22：
Once we recognize this dual vision, we can accept the play's ironic nuances as deliberate social commentaries by Hansberry rather than as the "unintentional" irony that Bigsby attributes to the work. Indeed a curiously persistent refusal to credit Hansberry with a capacity for intentional irony has led some critics to interpret the play's thematic conflicts as mere confusion, contradiction, or eclecticism. Isaacs, for example, cannot easily reconcile Hansberry's intense concern for her race with her ideal of human reconciliation. But the play's complex view of Black self-esteem and human solidarity as compatible is no more "contradictory" than Du Bois' famous, well-considered ideal of ethnic self-awareness coexisting with human unity, or Fanon's emphasis on an ideal internationalism that also accommodates national identities and roles.

7. Select the sentence that the author of the passage reinforce his criticism of responses such as Isaacs' to Raisin in the Sun
我选择的是“indeed a curiously...'.答案是最后一句。不知道是为什么，是因为题目在问reinforce嘛？

Exercise 24
Because of its accuracy in outlining the Earth's subsurface, the seismic-reflection method remains the most important tool in the search for petroleum reserves. In field practice, a subsurface is mapped by arranging a series of wave-train sources, such as small dynamite explosions, in a grid pattern. As each source is activated, it generates a wave train that moves downward at a speed determined uniquely by the rock's elastic characteristics. As rock interfaces are crossed, the elastic characteristics encountered generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments. The seismic records must be processed to correct for positional differences between the source and the receiver, for unrelated wave trains, and for multiple reflections from the rock interfaces. Then the data acquired at each of the specific source locations are combined to generate a physical profile of the subsurface, which can eventually be used to select targets for drilling.

5. It can be inferred from the passage that the seismic-reflection method would be likely to yield an inaccurate physical profile of the subsurface in which of thefollowing circumstances?
(A) If the speed at which the wave train moved downward changed
(B) If the receiver were not positioned directly at the wave-train source
(C) If the rock on one side of a rock interface had similar elastic characteristics to those of the rock on the other side
(D) If the seismic records obtained for the different sources in a grid were highly similar to each other
(E) If there were no petroleum deposits beneath the area defined by the grid of wave-train sources
这道题的答案是C。我后面看了太傻出的解析还是有一些不太理解

Legislator: We should not waste any more of the taxpayers‘ money on the government‘s job-creation program. The unemployment rate in this country has actually risen since the program was begun, so the program has clearly been a failure.

8. Which of the following is an assumption on which the legislator‘s argument depends?
(A) The budget of the job-creation program has typically increased every year.
(B) The unemployment rate would not have risen even more than it has if the job-creation program had not been in existence.
(C) The unemployment rate is higher now than at any time before the inception of the job-creation program.
(D) If the job-creation program had been run more efficiently, it could have better served its purpose.
(E) Other government programs are no more effective in reducing unemployment than is the job-creation program.
答案是B，我选择的是C。我觉得B是肯定对的，但是我觉得C也没有错误。C的意思和B基本相同：现在的失业率比这个项目开始前的任何一个时期都要高。

求各位大神讲解

1:reinforce his criticism of responses 就是让你选response的evidence，什么东西支持response,而不是response 本身

2. As rock interfaces are crossed, the elastic characteristics encountered generally change abruptly, which causes part of the energy to be reflected back to the surface, where it is recorded by seismic instruments.

3.把C忽略，这是不会对argument产生影响的，所以C不是assumption。并且注意C跟原文犯得是一个错误unemploy比较高，之前比较低，那时候job-recreation刚开始，所以这两者有关联？未必

那么快就有回复！好激动！
2这个题我定位的也是这句话。可是答案给出的如果两块rock给出的elastic characteristics比较相似，我觉得也不会影响测量啊= = 毕竟它只要测这块石头。然后之后可以再测旁边那块石头。
是我对文章本义理解错误么

不要加入自己的理解
which causes part of the energy to be reflected back to the surface
只有difference才能cause reflection
