Answer 1

哦~这个问题呀，想当年也难倒过我
这是一类问题，There is a new problem ______ road conditions need ______.

involved in the popularity of private cars是修饰road的，它具有一定的迷惑性，先不看它。
后面的that road conditions need be improved 是problem的同位语，而缺少的是这个同位语的连接词，同谓语从句可以用that引导，不能用which，所以第一空添that,第二空要用将来时的被动语态。
我是这么理解的，希望对你有帮助，祝学习进步~~~~~~！！

Answer 2

既然看到PROBLEM就有可能是同位语从句啊
involved in the popularity of private cars 这是定语修饰problem
NEWS IDEA PROBLEM等词后面要特别注意分辨定语和同位语
which定语从句？？NO。
road conditions need to be improved 这是个完整的句子啊
WHICH 做什么成分呢？？

Answer 3

在There is这种句式中要用that

Answer 4

need to be done=need doing所以第二空四个选项均可,关键是看第一空.

首先判断这是定语从句,前面是There is这种句式中一定用that.所以选A.

在定语从句中,一般情况下that和which可以互换,但有一般就有特殊.在以下情况中只能用that:
1.当先行词是all,anything,something,everything,nothing,little,much,none,one时,用that;
2.当修饰先行词的词为only,all,any,few,little,no,one of时,用that;
3.当先行词受最高级性容词,序数词,last,next修饰时,用that;
4.当先行词既表示人又表示物时,用that.
在以下情况中只能用which:
1.当关系代词前有介词时,用which;值得注意的是若把介词放到句末,that,which均可.
2.当关系代词后有插入成分,用which,如:
I have recieved your letter which,as I told you,is very important.
