lessen,v减轻,变少;lessening,n减轻
call female moths to them using acoustical signals,using做伴随状语修饰call,如何呼唤?用信号来呼唤
不能call by attracting,attract by calling还差不多,提主干。
C 题目讲catfish 这个选修讲其他鱼,我们还是不知道catfish是否能预测地震
A/B/D,it指代a synthetic growth hormone,错误
C,it指代the growth hormone,ok
别的网站上看的答案是C
overlay,覆盖,be overlaid;bank,堆积,be banked
E: - "That of his own" is redundant (and incorrect, because it literally means "Bill Monroe's music's music").
From Ron
B/D,依赖于他们的实施,而不是依赖于他们正在实施,帝国已经崛起,实施已经完成,用名词。
rest on依靠,以……为基础
rest,倚靠,系动词,只用主动式,如:
He rested his chin in his hands. 他双手托着下巴。
Their bikes rest against the wall. 他们的自行车靠在墙上。
as varied as=such as,sth as varied as A, B and C。如:
species as varied as sheep, cattle, mink, deer and people.
Wrong:species that are as varied as sheep, cattle, mink, deer and people.表示一定是和后面列举的羊等一样的物种。
that 是最明显秒选的split,and that this robe。。。要求前文也有that平行(B&E排除),而后文that不缺成分,肯定不是一个修饰作用的从句,所以 robe that错误,排除A&C
Defying efforts by policymakers on both sides of the Atlantic at restraining it, the United States dollar continued its rise, reaching its highest level in six years against the German mark.尽管大西洋两岸的政策制定者都在努力限制美元升值,但美元继续升值,兑德国马克汇率达到6年来的最高水平。
it指代its rise,A against B,A和B相比
A,they hold that, but instead that=they hold that, but instead they hold that,表示他们认为两件事情。这里说的是他们认为人类思维不是空盘,而是其他东西,认为的是一件事情。是人类思维有两个性质,所以not/but放在human mind后面。
如果下列哪一项是正确的,将削弱从文章最后一段所描述的实验中得出的结论的有效性?
【思路点拨】
定位最后一段
这种方法可以有效地控制有害藻类,同时使太阳能池成为最清洁的技术之一,为人类提供能源。
任何能让降低这个方法有效性的因素,都能削弱该结论。
A 沉入池塘底部的藻类细胞在24小时后才被破坏。 无关 方法能让藻类细胞沉到低,杀死藻类就行
B沉到池塘底部的藻类细胞的横向运动没有受到影响。 无关 方法能让藻类细胞沉到低,杀死藻类就行
C人工太阳能池被稀释的水中含有杀死藻类的微生物。 正确 原文提到藻类是在底部遇热死亡的,沉淀在底部,换言之,藻类需要活着才能吸水,下沉。 而微生物杀死了藻类的话,水藻就无法下沉,挡住了阳光的吸收,干扰了太阳池的使用。
D 下沉到池塘底部的藻类细胞实际上是被迅速变化压力杀死的。无关 方法能让藻类细胞沉到低,杀死藻类就行
E 通过蒸发带来的高盐度增加了池塘上层水的透明度。无关

A,将not only和simultaneously ,表示不仅,同时还,错误。固定搭配:not only..but also..;not only..but..;not only..also..或not only,后面不接比较对象
D,while表示同时,与simultaneously语意重复
avoid归属于禁止系动词,后面接(from) doing,这里的doing是动词,不是名词
sb avoid sth doing sth;sb avoid being done sth,doing的逻辑主语分别是宾语sth和主语sb,本题“space shuttle astronauts retrieved an orbiting satellite and simultaneously avoided being rear-ended by a passing ultraviolet telescope.” being rear-ended的主语是astronauts ,这些宇航员执行了一项操作,转向了一个航空器,同时避免了与一架经过的望远镜追尾。
可以用it appears that,但是在it做形式主语时,如:
It appears that there has been a mistake. 看来有一个差错。
It appears unlikely that interest rates will fall further. 看来利率不大会再降低。
;虽然可以连接两个独立句,但含分号的句子依然是一个句子而不是两个。
The ozone had appeared immune, but now we have realized……。had表示在我们意识到某事之前,人们不是这么看它的。
seem, appear, look,feel, smell, sound, taste是系动词,可以替换成be动词,直接接形容词;同时,系动词没有被动式,不管人还是物发起都用主动式,如:it tastes good; it appears nice.
