第一题是真的看不懂；第二题有点疑惑,好像哪个选项都行的样子；第三题选A为什么不可以；第四题为什么不选B.

根据你问的情况进行详略不同的回答
1.单词应该没问题吧,in degree 再某程度上；right away立刻马上
主干画出来 The Internet is different from newspapers in degree在某 程度上,网络和报纸不同
次要的就是 ...which users can voice their ideas right away.根据选项可只是靠定语从句,（多看看各种从句形式,区分一下引导词的不同,以及相同引导词翻译的差别）
接下来就是介词选择了,常用的是1.有固定搭配的就用固定搭配可见上述题找固定搭配的难找2.根据意思找介词users can voice their ideas right away.使用者们能立刻的发表自己的言论,（是地球人都知道只有互联网才能立刻发表,你说对不对）因此可见这句话是修饰The Internet 的因此句子变成了
The Internet （to which users can voice their ideas right away） is different from newspapers in degree
2.projected 规划的 town城镇的 选项词义（根据其他楼主我就不再说了）
成分 主干：Several experts have been called in 一些专家被号召.
目的状语to plan facilities for boating,tennis,refreshments and children's games in the projected town park.在建设城镇公园中规划一些公共设备用于boating,tennis,refreshments and children's games.
注意：facilities是专指公共场所的设施而其他的我就不多说了
3.句意,爸爸仍有一些感冒,但是,相反的,家人都很好.
你问的是Or & Othertise“否则”的区别 or是连词'特别在祈使句中.,or......,否则.（假设句中空要翻译成“否则”但是题中but已是连词,就不能用or) 而otherwise可以充当副词（假设句中空要翻译成“否则”但找不到修饰的动词或形容词）
因此,在这里otherwise是除此之外的意思是副词.
4.主干：The police finally found the man
定从：...had stolen the diamond necklace.修饰man
想一想 they thought将其去掉句子是不是也完整?因此很明显这是个插入语（以后多留心这种句式,很有规律的）
因此句子变成了The police finally found the man who/whom had stolen the diamond necklace.
学过定语从句中who引导主 &胃语,而whom只引导谓语.因此选A
