求高手详解!!!

Answer 1

it was between 1920 and 1930____television was invented in america.
a when b which c that d in which

答案： c that

1. 这是强调句式: it is + 被强调部分 + that + 其余部分
2. 如果不强调即：television was invented in america “between 1920 and 1930”。
3. 题目中强调时间状语：between 1920 and 1930
4. 强调句中只能够用 that

because of air resistance there is a limit to___fast an object falls
a why b how c when d what

答案：b how

1. 句子分析：
a）原因状语——because of air resistance 由于空气阻力的缘故
b) 存在句型——there is a limit to ...存在受...的限制
c)limit to ...: 意思是“限于，受到...的限制”
d）how fast an object falls是介词 to 的宾语从句
e）how 是连接副词，放在 fast 前说明快地程度，即“有多快”

Answer 2

第一句是强调句式，必须用that。

第二句是宾语从句，意思是因为有空气阻力，下落物体的速度是有一个极限的，要表示“下落物体的速度”这个结构必然应该是how fast an object falls

Answer 3

填that!It is +强调内容-that... 正是... .强调谓语用It does -动词原形 that... 感叹句型how-形,副容词-a/an名词 what--a/an形,副 -名. how beautiful a day! what a beautiful day !

Answer 4

it was between 1920 and 1920 in which television was invented in america
it will be easier to understand if this sentence is in this way: television was invented in between 1920 and 1930 in america.
2. because of air resistance there is a limit to how fast an object falls.
the choices of a, c, and d have no meanings if you put them into the sentences

Answer 5

1）定语从句中的从句是修饰先行词的，所以不局限于主将从现的规则，也就是说，从句是可以描述先行词的任何时态，当然，有的时候也会碰巧是主将从现的情况。
2）表语从句是说，整个一个从句做的是主句中系动词的表语，都有系动词做谓语了，主句为将来时的可能性很小了啊，将来时结构是什么啊？主语+will/shall+动词原形啊
我觉得主将从现主要针对的就似乎条件状语从句
明白了吗？
