数学题一定一定要读题仔细些!!!
If the total amount of one of her sales was $800=》sale是800...不是commission是800
想出做法了...但是脑子一热就没有验算...
求X的度数? (设X左侧的角叫S1, X右侧的角叫S2,则X+S1+S2=180平角)
1-条件一知三角形QRS是等腰三角形--->推出R+2S1=180;不能得出X,不充分;
2-条件二知三角形SUT是等腰三角形---->推出T+2S2=180;不能得出X,不充分;
(1)+(2)联立,加题干已知P直角 :
R+2S1=180
T+2S2=180
R+T=90
可推出S1+S2,同时X+S1+S2=180,即可得出X

注意:more than 2.5个标准差!!!是more than!!
把unlikely换成相似的否定词cannot就好理解了
Not being able to take college-level courses cannot deter anyone from a crime.
不上课就不能阻止人犯罪。(虽然否定的程度有差异,但大体都是这个意思)
但是没说上课能否减少犯罪。
如果能,那就是加强,不能就是削弱,因为上不上课都不减少犯罪,没什么用。
正因为待定,所以A选项给予原文的支持很模糊,不如C
目标不是减少更多硫,而是save money!
两个并列的句子或主从句的主语有代词时,代词与主语保持一致。
两个中的“另一个”是“the other”
不定数目中的“另一个”是“another”

assist sb. in doing sth.
'those of others' is problematic; it should just be 'others' (it's clear that the intention is to refer to other species, not to something of other species).
为什么转换过来不是k只能被偶数整除?为什么会多一个质因数的限制条件?
????? 不对吧。 R等于0怎么办
but adv.不过; 只是; 只; 另一方面;
fht exists before the advent of EU people |||| fht = private landownership

这段文章其实一共提出三个观点,前两个是引述,后面一个是文章观点。
前两个观点都承认family hunting territories是private landownership,区别在于前者认为欧洲人到来前,A人并未拥有这一private landownership,是和欧洲人的皮草贸易来带的社会变异以及生态环境等因素促成了A人拥有private landownership,后者认为欧洲人来之前,A人已经拥有private landownership。
第三个观点即文章观点:A人的确已经有了family hunting territories,但不属于private landownership。A人的family hunting territories是以几家合成的更大的community为单位,在精神上和社会上互利互惠,这和欧洲人语境下的private property完全不同,因此前两个观点把family hunting territories称作private landownership是错误的
commission a review采纳一个review
capability to do;GMAT认为capability of X-ing/in X-ing是wordy/awkward的。
ability:sb&aposs ability to do sth或ability of sb/sth to do sth
capability to do不如ability to do简洁,但不可就此判错。
be able to do
be capable of doing
have ability to do ; ability of sb. to do
have capability to do doing ; capability of sb. to do doing
没太理解,D选项people who retired and moved to another state,怎么就能确定这些人是搬到佛罗里达的?只说了to another state而已
