Answer 1

1. acquire v.多指经过努力逐步获得才能、知识、习惯等，也可用于对财物等的获得，该词强调"一经获得就会长期持有"的含义。
(1) She_acquired_a knowledge of English by careful study. (主谓宾+定语of English+状语by careful study)
(4)The school is giving most of these children hope for the future by providing them a chance to_acquire_knowledge.(楼主可以看出，知识的获取都用acquire knowledge)
The school--------主语
is giving-------- 谓语
most of these children ------ 间接宾语
hope-----直接宾语
for the future; by providing them a chance to....---------介词短语做状语
(5)It is through learning that the individual_acquires_many habitual ways of reacting to situations. 这个句子本人认为应该使用一般现在时，habitual ways 提示你这是“习惯性的行为”，用acquire. 句子本身是强调句式，it is + 强调的成分+that 从句。。。
the individual 主语
acquires 谓语
many habitual ways of reacting to situation 宾语
through learning 介词短语做状语

2 obtain v.获得，买到，用于正式语体中。
(2)I finally managed to_obtain__a copy of the report. （表示“获得、得到”，用obtain）
I 主语
finally 状语
managed 谓语
to obtain a copy of the report 不定式短语作宾语

3 gain v.指通过较大努力获得某种利益或好处；亦可指军事上的武力夺取等。
(3)The country_gained_its independence ten years ago. （“赢得独立”用gain）
the country 主语
gained 谓语
its independence 宾语
ten years ago 状语

4 earn v.挣得，赢得，指因工作等而得到报酬或待遇。
例如： How much do you earn a week?你一星期挣多少钱？
