b
首先第一空是分数的表达方式,表示几分之几时,分子用基数词,即one,two,three之类,分母用序数词,如first,second之类,当分子大于1时,分母的序数词应加s,即用复数
第二空,因前面有定冠词the,所以应为1970s,表示年代,20世纪70年代,在具体的年号前是不用冠词的,说 在1970年,应为in 1970

B

B
two-thirds “三分之二”
1970s “20世纪70年代”

D

B
英语中,表示分数时,分子要用基数词,分母用序数词。如果分子大于1,分母必须用复数形式。
“在1970年”是 in 1970,中间不要加the
in the 1970s的意思是“在20世纪七十年代”
