Many studies seem to link mental and physical exercise ____ a sound memory and a good health.
A.about B.for C.to D.at

A.equal B.was equal C.equaled D.equaling
选B,是observe sth.do的用法吗?这句话如何翻译?

1.C
link...to/with...是一个固定搭配,意思是“把...和...联系起来”.
2.答案B错误,正确答案应该是A（怀疑楼主看错答案或答案印刷错误）.
句子后面有occurred from.
occur是一个不及物动词,不可能用过去分词表被动语态,所以它在句中是过去式,做句子谓语.
由此判断后面是一个observed的宾语从句.
宾语从句中,an unexplained burst of light是主语,occurred是谓语,则 _____ in brightness to 600,000 suns只能是后置定语,用于修饰从句主语an unexplained burst of light.
根据固定短语be equal to...,可知答案为A.
B表示做从句谓语,这样和occurred就重复矛盾了；
CD为equal的分词形式,但是后面加to...的equal只做形容词,不能做动词.因为equal做动词时,是及物动词,直接构成equal sb/sth结构.

link to是不是固定搭配我不是很清楚，但是这就话的意思是将某某东西联系起来，具有趋向性，因此从语感上来说选择to更合适一些；
这句话的翻译是科学家捕获了在宇宙中某颗星星发过来的令人惊奇的光，它的亮度约等于600,000个太阳的光
1、是的
2、不是，这句话你在observed后面加个that 你就明白了。后面整个是个宾语从句。
