4The children themselves were calm enough ;____the parents that got into a panic.
a.in spite of b.those were c.it was d.however

Answer 1

1,B. that
I hope that后面是宾语从句（中间的东西下面讲）has been of some use.
the little（that） I have been able to do
我希望， 我能够做到的那一点点， 会有些用。
little , only , the one ,the only one , first 等序数词。
有以上这些时，定语从句只用that ，不用which
2,C.这句话的主句是后半句，这句话的谓语是is， 宾语是your permission，所以还需要一个词与I need连用，构成主语，就是说括号里要填的是必须是一个可以引导主语从句的连词，如that,whether,who,what,whatever。根据这句话的意思，需要填的是what，因为need是及物动词，所以不能用that，要用what（这里what相当于the thing that）
3,C.农村上现在种植的植物都是从原先的野生植物发展而来。
once是曾经，原来的意思
4,C.
孩子们都很镇定，他们的父母们却很惊慌
calm：镇定
get into a panic：惊恐 惊慌 恐慌
it is...that：表示强调
标准答案！望采纳！谢谢！

Answer 2

1.b the little，不定代词做先行词，指代事物，关系代词用that。
2.c all that=what（what引导名词性从句）
3.c that在从句中作主语，不能省略。
4.c 强调句型
祝你开心如意！

Answer 3

第一题 先行词做do的宾语 又有the little 修饰 所以只能选B that

第二题 由于是非限制性定语从句 所以不限 C和D all I need 是我只需要的意思 所以选B
第三题 农村上现在种植的植物都是从原先的野生植物发展而来。once是曾经，原来的意思，所以选C
第四题 it is...that：强调句型 孩子们都很镇定，他们的父母们却很惊慌
