竞赛题,很难,做选择的时候把我做蒙了,下面是辨错题,A B C D中有一个是错误的.1.If magnetic shielding is _lower_(A) over time,_changed_particles from the sun would penetrate _deeper_into Earth's atmosphere _and_create large ho
竞赛题,很难,做选择的时候把我做蒙了,
下面是辨错题,A B C D中有一个是错误的.
1.If magnetic shielding is _lower_(A) over time,_changed_particles from the sun would penetrate _deeper_into Earth's atmosphere _and_create large holes in the ozone.
就是说B是错的,请问错在哪,另外请问A为什么对,我不大懂.
2.on a _human-piloting_ aircraft 我把该句截了下来 横线部分是错误的,请问怎样改采正确?
3.Feelings of being powerful and invincible are not only typical,but _are_ some of the earliest reported effects of cocaine.
这里are是错误的.我猜想are去掉后是否就正确了?请问这里是什么语法点?
4.Unlike somespiders that weave a new web every day,a Golden Orb Weaver reuses her handiwork _after_ it falls apart,sometimes not for two years.
问这里after为什么错,怎么改

竞赛题,很难,做选择的时候把我做蒙了,下面是辨错题,A B C D中有一个是错误的.1.If magnetic shielding is _lower_(A) over time,_changed_particles from the sun would penetrate _deeper_into Earth's atmosphere _and_create large ho
1.你说的B是指particles前面的空格吗?
是的话,应该把changed改成charged(带电的)
整句话的意思是:如果磁屏蔽随时间逐渐削弱,来自太阳的带电粒子将会穿透至大气层的更深处,给臭氧层造成巨大的空洞.
2.human-piloted 意思是由人类驾驶的
这里涉及到构词法:名词+过去分词
在这种构词结构中,名词表示该动作使用的工具或行为主体.
人类(human)是驾驶(pilot)的行为主体.
而名词+现在分词的构词方式中,该名次与动词构成动宾的关系,显然,人类不是驾驶的宾语,所以错了.
3.not only...,but also...不仅……而且……
是固定的表达方式,所以应该把are改成also
4.根据句子意思,可以知道,某一种蜘蛛会重复利用它们织的网,直到网破掉.所以,应该把after改成till

1. changed可能应该是charged吧。A没有什么问题。
2. human-piloted
3. were;因为意思好像是很早以前,刚有cocaine的时候reported的。
4. until; 因为后边有“sometimes not...”所以不能说after
希望有帮助!
