This shop sells a variety of goods.这家商店出售许多种商品。
Half his goods have been stolen.他的一半财产被偷走了。
3．The majority of people in the town want to ...镇上大多数人赞成……

5．What do you think is likely to happen?你认为可能会发生什么事?
这是一个特殊的复杂疑问句，结构是：特殊疑问词+一般疑问句的插入语+陈述句。使用该句型应注意下面几个问题：
(1)位于句首的特殊疑问词如果不是该句的主语，一定要注意该句的语序。请观察下面例句。
Where do you think they should go?你认为他们该去哪儿?(Where不是该句主语)
Who do you believe／consider／suppose is right?你认为谁对?(Who是该句主语)
(2)不能用yes或no来回答这样的特殊疑问句，应用完整的句子来回答。
I think they'd better go to Shanghai。我认为他们最好去上海。
(3)适用于以上插入语的常用动词有think, believe, suppose,
imagine, guess, consider, suggest, say等。
Where do you suggest we spend our holiday?.你建议我们去哪里度假? 6．It's quite likely that a decision will be made before the end
of the year.很有可能在年底之前就会做出决定。
It's likely that...
(1)这是一种表示“有可能”的句型，相当于It's probable that(从句)的句型，其前的quite起强调作用，增大其中的可能性，表示相当有可能；也可用highly修饰，表示极有可能。例如，
It's highly(quite) likely that her birthday party will be held on
September 19th.她的生日晚会很有可能在9月19日举行。
(2)类似的句型还有It's possible that(从句)
Is it possible that she will marry a soldier?她会同一个士兵结婚吗?
(3)It is likely that(从句)的句型还可以作如下转换：
It is likely that we are not allowed to enter the building. = We
are not likely to be allowed to enter the building.有可能不让我们进入大楼。
