7. Impede=restrict

显而易见的，这两个单词的原意似乎并不接近。前者是 to delay or stop the progress of sth 阻碍；阻止，更接近与hinder，hamper，是标准的书面语。Eg. Fallen rock is impeding the progress of rescue workers.  

坠落的石头阻滞了救援人员的救援进程。

而restrict是 to limit the size, amount or range of sth，即限制，我们大家比较熟悉的意思。然而它还有一层意思，是大家不熟悉的，to stop sb/sth from moving or acting freely 即束缚；妨碍。这就说明，在所考察的语境中，后者的第二个意思和impede更接近。所以，这个答案的选项也就不让人意外了。所以再次提醒大家，TOEFL考察的是第二语言学习者，一次多义的情况很多见，大家做题的时候要进行语境还原，避免一叶障目的错选。

8. decipher＝figure  out

Decipher：to succeed in finding the meaning of sth that is difficult to read or understand 破译，辨认（难认、难解的东西）

Eg: The Warring States script is very difficult to decipher.

战国文字就像古老的密码,很难破译.

Figure out是to think about sb/sth until you understand them/it 弄懂；弄清楚，更接近于work out

Eg. I can't figure out how to do this.

我弄不懂怎样做这件事。

9. burgeoning＝increasingly

Burgeon为动词发芽（=sprout），可以积累这样的词组：burgeoning company 新兴公司 burgeoning industry新兴产业。

10. uniformly＝consistently

Uniform n.校服；制服 a.一致的前缀uni-表示"一个,单一"unilingual a. 只用一种语言的。

Eg. The middle button of his uniform jacket was strained over his belly.

制服上装中间的纽扣在他的肚子上绷得紧紧的。

The price rises will not be uniform across the country.
