不大懂一题十分~要有解析,不能只有答案1.It was in 1969--- the American astrouan

1。A 2。D 3。D 4。D 1,2题均为强调句型。强调句传统句式为 It is …that,不管强调的部分指人指物指时间指地点,只能用that。实际运用当中若指人也可说It is sb。who…;It is sth。which/that…。但绝对不能用It is some place where ；It is some day when的句式。3题中 be intersted in 固定搭配：对……感兴趣。in which=where,带入从句中意思不符,错；that 不可放于介词之后,错；all that可引导定语从句,可前面少了in,错；in everything 可理解我 be interested in everything (that) you told me,that代替的是在从句中担当宾语的everything,可以省略。4题 根据题意是问：修我这辆自行车你要收多少钱?不选pay 重点在repairing 此处repairing 是指修理的动作即是you动手来修,显然要me来付修理费。若改为pay for the repair of my bike则意为you 搞坏了我的车要赔我修理费,此时用repair指修理的事实,为名词。
