3/27 加拿大, 差!
考了个很差的成绩,不过还是由于自己没有认真复习.

AWA:
100. The following appeared as part of an article in the book section of a newspaper. “Currently more and more books are becoming available in electronic form — either free-of-charge on the Internet or for a very low price-per-book on compact disc *. Thus literary classics are likely to be read more widely than ever before. People who couldn’t have purchased these works at bookstore prices will now be able to read them for little or no money; similarly, people who find it inconvenient to visit libraries and wait for books to be returned by other patrons will now have access to whatever classic they choose from their home or work computers. This increase in access to literary classics will radically affect the public taste in reading, creating a far more sophisticated and learned reading audience than has ever existed before.” *A “compact disc” is a small portable disc capable of storing relatively large amounts of data that can be read by a computer. Discuss how well reasoned . . . etc. AI: 2. “It is unrealistic to expect individual nations to make, independently, the sacrifices necessary to conserve energy. International leadership and worldwide cooperation are essential if we expect to protect the world’s energy resources for future generations.”
MATHS:
1 ds.x^3*y ^4=5000, y =?(去年3月JJ)
1)y is a positive integer
2)x is a integer .
橙子评价:选C,由条件1,2推出X=2,Y=5
19..ps.5个人考试，分数从0-100 (都为整数，而且个人分数都不相同) 。其中已知中数为 65，问平均数最大为多少。(今年2月JJ重复题目) (重复两次)
橙子评价:78.2,平均数最大,5个人的分数分别为100,99,65,64,63
20.ds.X为集合(A，B，C，D) 中的一个， A= 1.235, B =2.239, C= 3.278, D = 4.225, 问 X为其中哪一个，(数字可能有误)(2月JJ重复题目)
1。千份位数大于7
2。百分为数小于4
橙子评价:选C,满足条件1,X 可能为B或者C,满足条件2,X可能为A,B,D,结合1,2, X只能是B

21.ds.一个商店卖 digital camera and video camera. The number of digital sold is twice the number of video camera. Ask: the average price of digital and video.(2月JJ重复)(重复两次)
1. the unit price of digital
2. the unit price of video.
橙子评价:选C,可以分别求出总收入
34. ds. x,y,plate. O 为原点，N在第二象限上， P在第三象限上 ON=OP=3 问（-1，-1） 是否在OP上。(重复三次)
1. (-2,2)在ON上 2. NOP 是直角。
橙子评价:选C.由条件1确定ON斜率为-1,再结合条件2推出OP斜率为1,从而推出(-1,-1)或者(1,1)在OP上.

39.xyz>0,xy^2z^3>0? (去年3月JJ) (重复三次)
1).Y>0 2).X>0
橙子评价:选A,又条件1+题干Y>0-->XZ>0,所以XZ^3>0既XY^2Z^3>0
91.ds R=P/Q, R>=P?
1.P>60 2.0<Q=<20
作者答案：E
橙子评价：同意，Q>1时,P>60 R<, 0<Q<1, R>, Q=1 R=P
94.ds.y=z+x?
1. |x|+y=z 2. x<0
橙子评价：选Ｃ，由条件２－＞|x|=-x->条件１，-x+y=z->y=z+x

121.ps.cube,相邻三个面的对角线构成的三角形其中一个角多少度?(去年三月JJ)
作者答案:我答60度。因为三边均为一样长短。
橙子评价:同意,是等边三角形 阅读就是, WAGE 和 WEEK EFFIECIENT
