1.(Visibly )only through large telescopes,Pluto (has) a yellowish color,which indicates that (there) is very (little) atomosphere.答案是A,应改为visible

2.(Essential )a nineteenth-century instrument,the calliope was usually played outdoors and was (a part) of fairs,(holiday) gatherings,and( other such )activities.答案是A,应改为essentially

为什么上面这两道题，第一个得用形容词，而第二个要用名词？

3.Collagen,a (strong) rubbery protein,(supports the) ear flaps and the tip (of nose) in (humans.)答案是d,应改为单数

可数名次单数不能单独出现吗？nose 可数名次单数，为什么没有错？human表示人类，是不可数，对吗？

4.Science fiction is any (fiction dealing) with the future or with (so) imaginative subjects as interstellar travel,(life） on other planets,（or） time travel.答案是b,应改为as

life 是可数名次，为什么能单独出现？

名词能不能单独出现，感觉搞不清，有的题名次单数，没有冠词就错，有的就对？希望有人能讲讲，谢谢！

1.visible是which is visible的省略

2.作句首状语，用副词

3.我记得是C错了吧

4.短语as ... as，life在这里是抽象名词，不可数

抽象名词不可数，但是表示种类的时候是可数的，区分他表达的概念

可数名词不能单个出现，肯定要加定冠词

忘了说一句了，麻烦你发贴的时候表明一下出处，哪一年额达哪一题，谢谢方便大家
