of the following must be true?
Han is scheduled to give the first address.
Han is scheduled to give the fourth address.
Ngo is scheduled to give the second address.
Lu is not scheduled to give the second address.

答案：(A)
读题：4个演讲者被邀请在会议上作演讲，会议以四种语言进行，H（k）、L（m）、N（v）、
T（j），演讲在连续的4个晚上，必须被同时翻译为其它3种语言，有4个翻译。
写条件：
1、～(iii)m (翻译为m语言的翻译不能连续工作3天)
2、～(HN) (H、N的演讲不能紧密相邻)
3、T
条件总结：
*条件1有～(iii)m，也就是说不能连续3天没有L作演讲，而一共只有4天，
所以L≠1,4, L=2/3，我们由此得到了一个相对固定的条件，到此，题目也变简单了。
（善于把一些条件与题目中的数字或具体确定的条件联系起来一直是我们强调的）

the following must be true?

Healthful exercise causes the body to lose electrolytes,
such as sodium and potassium, in sweat. To restore the elec-
trolyte balance in body fluids. drink our specially formu-
lated sports drink containing sodium and potassium when
you pause during a competition.
The rationale given in the advertisement above is poten-
tially misleading if which of the following is true?
Cooling off quickly by taking too large a drink during
a sports competition can cause an athlete s concentration
to lapse.
During exercise the body loses proportionally more water
than electrolytes, so the concentration of electrolytes in
the body increases.
Like many soft drinks, the specially formulated sports
drink advertised contains a larger amount of sugar by weight
than of substances composed of sodium or potassium.
For peak functioning of muscle tissue, a proper concent
ration of electrolytes in body fluids is necessary.
Some athletes choose to wait until the end of a competi-
tion to restore the balance of electrolytes in their bodies.

答案：(B)
Stone Age potters crafted complicated and often delicate
ceramic pots, tools, and jewel. They also crafted crude
pottery figurines. Many of the delicate ceramic pots,
tools, and jewelry have been found intact or nearly so,
whereas the figurines, crafted at roughly the same time
as the ceramics, have largely been found in tiny fragments.
Which of the following, if true, best explains why few
of the pottery figurines, but many of the delicate ceramics,
have been found intact?
When a pottery piece from any batch was broken during
finishing, Stone Age people sometimes deliberately smashed
the rest of that batch, perhaps to avert bad luck.
