C,同一个句子里对一个主语可以既有主动动作又有被动动作。
eg.:The shuttle launch took place flawlessly and was seen on television.
found in the Philippines and resembling a hummingbird可以平行
unlike sth,unlike作介词,接名词构成介词短语介词短语可以做定语,The cat in the room is mine,也可以做状语,I left Shanghai in 2019.
这里unlike smallpox vaccine做伴随状语,表示与Most vaccines起源于什么什么样的病毒这件事情不同,伴随状语用主句的主语,A unlike B,A和B要平行,主句主语与unlike接的名词也要平行。
A,not only/but also是从属连词,后面接动词时不用接助动词,构成don't only/but also
如:The Americans and the British not only speak the same language, but also share a large number of social customs.
C, the chains they build complexes where ……,where……修饰complexes,表示他们在complexes可以做……;the chains they build complexes,they build complexes不可以做定语修饰chains,因为先行词没有在句子中充当成分。只能把they build complexes看成是省略了that的同位语,同位语起解释说明先行词内容的作用,chains的内容并不是they build complexes,同位语错。这里应该要加一个where,他们在chains里build complexes。
老师的答案有点问题。工作未必是整数小时,题中给出是超过4不到整数小时(or fraction of an hour)也是收费0.2r。因此超过4小时的收费应该是【x-4】的取整运算,大于等于(x-4)的最小整数。带入(2)得出【t-4】=7。所以t>10。因为t=10,该式=6,t=10.1,该式=7.
B,Unlike spices that are used in cooking, spices are taken in large quantities in using spices for medicine,
(1)Spices are taken in using spices重复,(2)辣椒在医疗领域被大量使用,不像被用在饮食上的辣椒。没有比较出是二者的用量不一样,比如也可以看成是用在医疗领域的是A品种的辣椒,不同于用在饮食领域的是B品种辣椒。
D,In cooking, small quantities of spices are used, whereas in medicinal usage spices are taken in large quantities. 前半部分的主语是quantities,表数量,可以将实质主语看成是辣椒,少量的辣椒被使用,与后面的句子平行。
E,前句的主语是the usage of spices,usage,与后面的句子不平行。
was not responsible for the debacle这句话与原文的意思已经不一样了,一定要尊重原意!!!
