Until the very latest moment of his existence, man has

developed. Now he had the capability to leave that planet ___1___
and move out into the universe to those worlds which he has
known previously only directly. Men have explored parts of ___2___ the moon, put spaceships in orbit around another planet and
possibly within the decade will land into another planet and ___3___ explore it. Can we be too bold as to suggest that we may be ___4___ able to colonize other planet within the not—too—distant ___5___ future? Some have advocated such a procedure as a solution
to the population problem. ship the excess people off to the
moon. But we must keep in head the billions of dollars we ___6___ might spend in carrying out the project. To maintain the earth’s population at its present level. we would have to blast off into
space 7,500 people every hour of every day of the year.
Why are we spending so little money on space ___7___ exploration? Consider the great need for improving many ___8___ aspects of the global environment, one is surely justified in
his concern for the money and resources that they are poured ___9___ into the space exploration efforts. But perhaps we should
look at both sides of the coin before arriving hasty conclusions. ___10___
答案：
1. had -> has
2. directly -> indirectly
3. into ->onto / on

考点例析：
例1：If his aim is inaccurate and he scores a goal, enjoys S3.____
the hunter’s triumph of killing his prey.
解析：这是由一个条件状语从句引导的复合句。但主句只有谓语动词enjoys，缺少主语，因此要步上主语。根据从句的his aim可推断应该加上主语he。
例2：Nuclear physicists who interested in the structure of 5._________
atoms cannot observe protons, electrons and neutrons
directly.
解析：如果将who后面的部分作定语从句，那么它绝少谓语，故将who去掉，此时分词短语interested in直接作定语修饰前面的physicists。或在who后加are，补全定语从句。
例3：This alliance guarantees that all leprosy patients, even they S6.______
are poor, have a right to the most modern treatment.
解析：even是副词，后面不能直接跟句子，根据句子的意思，应该在even后加if或though。

巩固与拓展：
1. 在performer后加as
此处为同级比较，固定结构为as...as...，而原句比较的对象a medical student前缺少连词as。
2. want -> wanting或those后加who
for为介词，后面的宾语时代词those，不可再跟主谓结构。故将want改为wanting，用现在分词短语作定语修饰those，或者在want前加who构成定语从句修饰those.
3. inaugurate后加it
4. made后加it
句子主语是law，谓语是made，easier是宾语补足语，逻辑宾语是to get a divorce，可见此
