convert A to B,把A转换成B,这是是全部替换,把A扔了换成B;convert还可以表示改装,convert a car or equipment to do sth。A:convert gasoline-powered trucks to run on cleaner gas.把烧汽油的车改装成烧清洁能源,车子还是那个车子,只是能源系统改装了。如果是convert gasoline-powered trucks to trucks that run on cleaner gas则是把烧汽油的车扔了,换成烧清洁能源的车。
P.s:我自己瞎掰的,得找点方法理解它,不然这道题下次还是错……
1、当不定式的动作执行者不是句子的主语时,不定式的前面要加一个名词或代词来充当不定式的逻辑主语。
SV+for/of sb to do sth,如:I buy a pen to write,我来买我来写;I buy a pen for you to write.我来买你来写。
D,UPS plan for trucks to convert,Ups来计划,卡车来转换,卡车不会自动转换,是人使它转换,主语错误。
E,UPS plan that truck will convert to run on cleaner gas,
2、 plan可以接名词,如:plan a trip,计划一场旅行。但plan不能接that+宾语从句。还是主语的问题,plan+that表示计划其他人做某事,只能计划自己做,不能计划其他人做,比如计划让其他人做某件事,也是计划我去让他们做,而不是直接计划其他人做。所以计划后面接动作的,用to do,不用that。
同位语从句是用于说明所修饰名词的具体内容的,它与被修饰词语通常可以划等号;而定语从句是限制所修饰名词的,它的作用是将所修饰的名词与其他类似的东西区别开来:
一点点阿斯匹林就足够阻止T产生,which is a substance that promotes blood clotting,(T物质的)一个特征是防止血凝块; a substance that promotes blood clotting,(T是)一种防止血凝块的物质
这里是对T进行解释,它是一种防止血凝块的物质,而不是描述它的一个特征是防止血凝块
可以可以,精辟
thanks for explanation !
我也是真的傻,看了无数遍才发现比较的是两个时间点而不是两个人,我怎么会一直以为是两个人呢?(German是德国人,Germany是德国)
比较的对象应该是:after she emigrated to New York 与 she had been in her native Germany(德国,不是德国的,老是搞错!影响理解)
A,E是两个完整句子中间没有连词,错;B,D没有than
请问为什么which is more than all the North American Great Lakes combined修饰20 percent of the world's fresh water是错误的呢?A选项不也是more than all the North American Great Lakes combined修饰20 percent of the world's fresh water 这样吗?
a选项morethan...是做状语修饰前句hold主语是which 也就是SIberia's Lake Baikall吧 但是D是作定语从句 虽然说可以跳跃修饰 但是根据句意 应该做状语更好(个人理解 不一定准确)
If the laboratory's original bill for this medical test on a patient referred by the insurance company is $230,这句话on a patient是修饰前面的test的,也就是说这个test是一个病人的test,on a patient是限定作用,所以一个test对应一个病人
最后一道题 解不出来3 貌似, 不是整数
我也没看见。。。。
through更多强调通过某种渠道,穿越某种实体(墙壁、森林、城市)或虚拟的物体(through night),或表示通过某种方式;in是在里面。在这个实验里(实验进行的过程中)老鼠被移植骨髓,而不是穿越/通过这个实验,老鼠被移植骨髓。
关于CE的时态,mice have received老鼠是现在被移植,这意味着实验现在进行,其结果还没有出来,所以实验能提供有用的信息这件事情是一个期待,尚未发生,用将来时。
首先不能用causing,主语是宿主,宿主不会引起疾病,是cowpox引起疾病。
关于时态,found过去发现,they were infected,过去被感染,感染后获得免疫力也是过去的事情,所以能够免疫这里一定是过去时。
Ida就是那个mn的人,我还以为星星一开始被叫mn的人,后来又被叫做Ida。一个叫mn的人作为ida的逻辑关联部分,要离Ida越近越好。
果因推理
P:some people have suffered a serious stroke on the left side of the brain without suffering any such impairment
C:they must have their language centers in the right half
评估方向:要么同时提及“without any such impairment” 和 “language centers in the right half”,要么给出“without any such impairment”的另一个原因
主旨题:通篇讲了continental drift在当时被拒绝,以及探讨被拒绝的原因
To most geologists today, Wegener's The Origin of Continents and Oceans appears an impressive and prescient document, containing several of the essential presumptions underlying plate tectonics theory.
高亮部分作为伴随状语修饰main clause: appear impressive and prescient -> choice b, show why W's is regarded as prescient
e。 saw lien laws as a way
saw。。as a way,。。把。。看成。。的方法
句子作用题:举例Anthony Hallam是为了 refute that 'Wegener's theory was rejected because of its lack of an adequate mechanical basis'
排除法做这道题
Planters planned to use their supply credit to control their workers, former slaves who were without money t
workers就是former slaves
作用题:提到overlap between plate tectonics theory and Wegene's concepts, 是为了铺垫后面geologists rejected Wengene's idea 是非常surprising
"three times the price of what the drug's maker charges" would refer to the price of a price. that is illogical.
