(A) 正确,difference in sth,help sb do sth。
(B) in the two ears hearing … 去掉how改变原文要表达的含义;help in doing用法错误。
(C) 被动语态的表达没有必要;helps应该是help,因为其主语是复数differences。
(D) between应该是用于表达“二者之间”的含义,用于此处不正确;helps应该是help。
(E) between应该是用于表达“二者之间”的含义,用于此处不正确;被动语态的表达没有必要。
树木生长的速度被认为是地球上太阳黑子周期最可靠的迹象之一
(A) among倒装,主语应该是the rate,所以应该用单数is。
(B) among倒装,主语应该是the rate,所以应该用单数is;tree应该用复数,使未划线部分的their有 一致的指代对象。
(C) on earth 放置句首修饰整个句子,不符合逻辑;their 的指代存在歧义,离它最近的是 sunspot cycles,未划线部分的 as seen 应该要紧跟其修饰的名词。
(D) tree应该用复数,使未划线部分的their有一致的指代对象;谓语结构不完整,应该用is believed被动语态。
(E) 正确,on Earth修饰indications,主语是the rate,谓语动词用单数is。
on earth是一方面,但不是硬伤。硬伤来自于后面 as seen的修饰对象。as seen说的是“正如(我们在)树桩上的年轮所看到的那样”。从语义上,应该修饰树的成长,把句子还原就是,trees grow at the rate as seen in the rings visible in the cross sections of their trunks. 树木增长的速度,从树桩上年轮的圈上可见一斑。
C选项,使得as seen的修饰对象变成了sunspot cycles,语义完全错误了。
as seen做伴随状语逻辑主语在C和E中都是trees吧 从这点上来说C不存在问题
1) 语意重复,may与likely所表达的都有“可能的”含义,不能同时使用。
2) because of…的表达不及动词形式cause更有效。
(A) may与likely语意重复;此处不应该用关系代词where,因为没有明确表示地点。
(B) may与likely语意重复;each…the other搭配错误。
(C) be because of sth不及动词形式be caused by更有效;each…the other搭配错误;where用法错,原因与A选项相同。
(D) where用法错,原因与A选项相同;each…the other搭配错误。
(E) 正确,be caused by简洁有效地表达原因,现在分词orbiting…作后置定语修饰名词stars。
(A) compared to的比较对象不对等,前者419 times the pay of blue-collar workers表达的是工资数, 而后者a ratio of是比率。
(B) a ratio that compares的compare不能用主动方式表达,应该是被比较sth be compared to…的省略形式(省略了主语和系动词,是惯用法);compare to的比较对象不对象等,前者表达的是工资数,而后者42 times是比率。
(C) 正确,as compared to比较结构,419 times the pay与42 times their pay比较,the ratio…是同位语。
(D) 缺少that引导宾语从句;indicates CEO's who…句子结构不完整,缺少谓语,who引导定语从句 修饰名词CEO's。
(E) 缺少that引导宾语从句;indicates CEO's earning…句子结构不完整,缺少谓语;compare to的 比较对象不对等,前者表达的是工资数,而后者42 times是 比率
having修饰主句主语 Industrialization and modern methods,逻辑语义错误,排除
选项C (Industrialization and modern methods have improved the standard of living around the globe) ,and( have gone virtually unregulated since they were developed more than 50 years ago.)and前后不平行,前面是完整句子,后面不是;
选项D ( have improved) the standard of living around the globe but( introducing) 括号内不平行
选项E have done 和do不平行;having修饰错误
(A) 正确,aspirin与blood-thinning drug在prevent blood clots上的比较,does指代prevents,补出以 避免歧义。
(B) a commonly used and a more expensive中的第二个冠词a多余,使得句意变化,成为两种drug。
(C) 助动词will应该为does,因为原句用的一般现在时prevents则不是将来时态。
(D) works at prevention of…的表达方式啰嗦;缺少助动词does。
(E) works at preventing…的表达方式啰嗦;which引导定语从句修饰drug啰嗦,不如直接用形容词作定语。
B growth是个名词, 不能用more来形容。可以说 grow more但不能说growth is more。growth应该是higher
C 不用had been。句子里没有过去式标志
D 不用has been,过去那段时间的增长对现在没有影响了
E it did有问题,did在前面没有比较对应
没看到did not o(╥﹏╥)o
原文:Clearly price promotions are generally run at a loss, otherwise there would be more of them.
所以 没有经常举办这个活动的原因是因为run at a loss即亏本,没有利润
问题问价格促销对于利润的影响(即没有利润)的证据是什么,就是因为没有经常举办这个活动呀,没有经常举办这个活动就是它亏本的证据
说的好,太强了
我都定位到了,也理解这个意思,就是没反应过来more of them=frequency
错选C,C其实说的是native birds,不是migratory birds
E应该改为which is now commonly called
m is a multiple of pt
since m is also a multiple of p3, then m must be a multiple of p2. (e,g. p=2, m can be divided by 8, then m can also be divided by 4.)
so m is a multiple of p2t
另外,一般说prescribe sth for sb 不说 prescribe sb sth
prohibit/inhibit/prevent/stop/deter sb from doing sth,禁止/阻碍/阻止某人做某事
forbid sb. to do sth. ,be forbidden to do sth不允许
也可以说forbid sb. from doing sth. ,但书面语里用 forbid to do
一般来说,begin to do和begin doing可以互换,但在以下三种情况下,用to do:
1.主语不是指人,而是it等.如:It began to rain.
2.begin后接表示心理活动的词.如:begin to know
believe,wonder,think等.
3.begin本身是ing形式,为避免重复后接to do
即,beginning to do
weighing作状语修饰最近的动词,B错
A与C的主句都是the electronics company has unveiled what it claims....不能和it weighs less than 11 ounces对等
B选项having an eccentric personality不如her eccentric personality来的好来的直接;原句应该是要表达PLW因为她的eccentric personality出名而不是因为 “有” eccentric personality而出名
the correct idiomatic expression with 'differ' is 'differ in...', so a-b are out. (if you said 'differ because', you'd have to give the reason behind the genesis of the difference, not the nature of the difference itself.) that leaves c-d-e, which all contain the supposedly ambiguous pronoun.
选项A instead of at的 at 不能省;不能意思可以变成they are attached to the wrist.
DNA是单数
A:
- 'those of' doesn't refer to anything (it would need to refer to something plural, and there's nothing plural for it to refer to)
- 'with' serves no grammatical purpose, and destroys parallelism because 'with' dosen't appear in the second part
- 'as' should be 'like'
the budget-deficit explanation 指出的原因是interest rate太高了. 答案E表述的是如果利息高的话,会降低growth of manufacturing productivity 和growth of service-sector productivity同样多, 所以就不会有discrepancy. 但是事实是利息高了,结果是出现了discrepancy, 所以如果答案E表述的情况是真实的,那么就是最weaken the budget-deficit explanation.
