How do the airlines expect to prevent commercial planecrashes? Studies have shown that pilot error contributes to two-thirds of allsuch crashes. To address this problem, the airline have upgraded their trainingprograms by increasing the hours of classroom instruction and emphasizingcommunication skills in the cockpit. But it is unrealistic to expect suchmeasures to compensate for pilots’ lack of actual flying time. Therefore, theairlines should rethink their training approach to reducing commercial crashes.

Which one of the following is an assumption upon which theargument depends?

A.     Trainingprograms can eliminate pilot errors.

B.     Commercialpilot routinely undergo additional training throughout their careers.

C.     The numberof airline crashes will decrease if pilot training programs focus on increasingactual flying time.

D.     Lack ofactual flying time is an important contributor to pilot error in commercialplane crashes.

E.     Communicationskills are not important to pilot training programs.

能不能讲讲C和D的区别，更深点就是加强及弱化与ASSUMPTION的区别～～

D和e我觉得是加强，但是并非是前提条件。

School superintendent: It is a sad fact that, until now, entry into the academically best high school in our district has been restricted to the children of people who were wealthy enough to pay the high tuition. Parents who were previously denied the option of sending their children to this school now have the option, since I am replacing the tuition requirement with a requirement that allows only those who live in the neighborhood of the school to attend.

The superintendent’s claim about the effect of replacing the tuition requirement relies on the assumption that

A.        the residents of the school’s neighborhood tent to be wealthy
B.        people other than those wealthy enough to have paid the old tuition are able to live in the neighborhood of the school
C.        people less wealthy than those who were able to pay the old tuition are in the majority in the district
D.        there are no high schools in the district other than the one referred to by the superintendent
E.        there are many people not wealthy enough to have paid the old tuition who wish to have their children attend the school
这个题呢？能不能讲讲？
