这段时间一直在纸上做题, 今天到机上, 发现阅读速度跟不上, 我的眼睛似乎不愿快速移动,
哎...

还是在纸上做题好，眼睛不容易坏。我现在读OG用书本了。

但是可以说the first thing is do sth. 吗？怎么说也要接个TO 或动名词吧？

可以,og上有类似的题目.

请教KAPLAN的两个语法题：

Kaplan-2-5
At a recent conference, the Transit Authority has stated that the provisions in the Clear Air Act fail to promote mass transit as an alternative to provide transportation.
A. has stated that the provisions in the Clear Air Act fail
B. stated that the provisions of the Clear Air Act fail
C. has stated that the provisions of the Clear Air Act will fail
D. stated that the provisions in the Clear Air Act are a failure
E. has stated the provisions in the Clear Air Act failed
Ans: B, I choose A
EX: The Transit Authority made their statement and it was over. The action didn’t continue.
我用完成时，是因为有个recent，时态的判断对我来说，是个难点，该如何解决？
Kaplan-2-14
Modern inventions such as PD may seem to have improved the work conditions of manual laborers, but in fact, have increased the incidence of health hazards such as S because it has aggravated the dust liazard involved in excavation and demolition.
A. have increased the incidence of health hazards such as S because it has aggravated the dust hazard.
B. Has increased the incidence of health hazards such as S because it has aggravated the dust hazard
C. Have increased the incidence of health hazards such as S because they have aggravated the dust hazard.
D. Increased the incidence of health hazards such as S because they aggravated the dust hazard
E. Increased the incidence of health hazards such as S because of aggravating the dust hazard
Ans: C , I choose D
EX: There’s no reason to use the past , because the hazard is still happening.
我选D，是因为未划线的句子有个虚拟的意思，本该提高工作条件，而事实是。。。所以我用一般现在时。为什么不对呢？

谢谢。

注意表达时态的词是a recent conference,而不是recently,at a recent conference表示过去的一个时点,特别是at 这个词表达了这个意思.
第二题要从整个句子的时态一致性上和主谓一致上来解答.

请教OG的DS
T235， 答案是C，我选了E，我认为1和2都没有讲到during a 3-day period啊？

T241，答案是A，我选了D，2中every prime factor of S is also a prime factor of R.
讲的是every啊，所以我想这两个数质因子是一样的。所以选D

谢谢。

第一题我觉得expected这个词已经包含了during the period的意思了.
第二题假设r=3*5 ; s=3*5*3, 结果就不是整数了.

MIKE,第二题能再说说 吗？谢谢。

mm,我觉得最好不要在纸上作了，还是尽早适应在机上作，这样考试就不慌了！

这题总的时态是现在完成时,从未画线的seem to may have...以及句意可以确定。至少可以排除过去时，因为全文都没有出现一个表示过去的时间。

可是哪里可以判断是完成时呢？我觉得前面有个虚拟的意思在。所以用HAVE 。。。，后面没有完成的意思啊？时态上我一直不太好。全文也没有出现一个表示完成的时间啊？

mike1999

即使是虚拟也不应该单用过去时,况且may seem to have improved好象不是虚拟吧.如果是虚拟要改为would have improved

请教全划线一道
10. The development of a new jumbo rocket that is
expected to carry the United States into its next
phase of space exploration will be able to deliver a
heavier load of instruments into orbit than the space
shuttle and at a lower cost.

(A) The development of a new jumbo rocket that is
expected to carry the United States into its
next phase of space exploration will be able
to deliver a heavier load of instruments into
orbit than the space shuttle and at a lower
cost.
(B) Originally developed for detecting air pollutants,
having the ability to analyze the chemical
elements in almost any substance without
destroying it, a technique called proton-
induced x-ray emission
(C) A technique originally developed for detecting
air pollutants, called proton-induced x-ray
emission, which can quickly analyze the
chemical elements in almost any substance
without destroying it,
(D) A technique originally developed for detecting
air pollutants, called proton-induced x-ray
emission, which has the ability to analyze the
chemical elements in almost any substance
quickly and without destroying it,
(E) A technique that was originally developed for
detecting air pollutants and has the ability to
analyze the chemical elements in almost any
substance quickly and without destroying the
substance, called proton-induced x-ray emis-
sion,
答案

我选了C。have the ability是修饰人的，所以C和D比，我选了C。

为什么不对呢？谢谢。
