新概念英语第二册第四课答案Lesson41.d根据课文内容Timisanengineer.Heisworkingforabigfirm...,只有d.Timisworkingforabigfirmasanengineer是对的，其他3个与文章不符合。
2.b根据课文的最后一句Mybrotherhasneverbeenabroadbefor,e,应该选b.其他3个选择都与课文内容不符合。
3.ab.in(在,,里面)不能和动词go连用；c.at（在,,地方）也不能同go连用；d.into(进入,,内)可以与go连用，但是到某个国家不能用gointo；只有a.to同动词go连用goto才能表示到某个地方去，如国家，城市等，所以选a.4.b本句是问“他在那儿呆了多久”。
因为说话时他还在那，所以应该用现在完成时态。
a.ishe是一般现在时；c.hashe中没有过去分词been,不符合语法；d.washe是一般过去时；只有b.hashebeen是现在完成时,所以选b.5.ba.for只有同表示一段时间的词连用时候才能用在完成时中,如forsixmonths,foroneyear等.c.from常与介词to连用表示"从,,到,, "，它很少用于现在完成时；d.by可以表示时间“到,,为止”，常用于过去完成时中和将来完成时中，但是它用在本句意思不对；只有b.since(从,,以来)可以用在完成时态中，选b.才能使句子的时态和意思正确并且合乎逻辑。
6.a本句的意思是“他刚刚买了一辆澳大利亚小汽车”强调买的时间短，用just来表示。
b.alongtimeago(很久以前)与原来句子不符合。
styear(去年)也跟原来句子不符合。
d.sixmonthsago(6个月 前)也不对，句子中没有明确说明；只有a .a shor tt im ea (久前，最近)同just 的意思相近，所以应该选a. 7.c 本句需要用现在完成时，已经给出了助动词has,只需要填上过去分词就可以了。
