参考范文：
Recently our class had a heated discussion on whether space is worth exploring.Students hold different ideas about it.
30% of us think space exploration is not worthwhile，holding the belief that space exploration is too far away from us and our daily life and is a waste of money.However, 70% think space is worth exploring because we have benefited a lot from it, such as using satellites for communication and weather forecast.What's more, with further space research, we may solve the population problem by moving to other planets one day.
As far as I am concerned，it is worthwhile to explore space.Not only can it promote the development of society but it can also enrich our life.UNIT 4 Section Ⅳ
夯基提能
Ⅰ.阅读理解
It's possible that interstellar (星际的) space explorers could come across problems communicating with previous and subsequent arrivals, as their spoken language has changed in isolation along the way.
Regarding the issue, two American scholars, Andrew McKenzie and Jeffrey Punske, co-authored the article “Language Development During Interstellar Travel”．What has been discussed in the article is the concept of language changing over time.They wrote that given more time, new grammatical forms can completely replace current ones.
In a recent interview, McKenzie gamed it out.“If you're on a spaceship for 10 generations, new concepts will emerge, new social issues will come up and people will create ways of talking about them，”McKenzie said，“and these will become the particular vocabularies to the spaceship.People on Earth might never know about these words, unless there's a reason to tell them.And the further away you get, the less you're going to talk to people back home.”
So if we have Earth English and spaceship English, and they become different over the years, you will have to learn a little Earth English to send messages back, or to read the instruction manuals and information that come with the spaceship.
Also, keep in mind that the language back on Earth is going to change, too, during that time.So they may well be communicating like we'd be using Latin—communicating with this version of the language nobody uses.
The authors concluded that if a study of the linguistic changes aboard a spaceship could be performed, it would “add to its scientific value”．
语篇导读：本文是一篇说明文。文章围绕语言在未来是如何变化而展开，探讨了人们对此的不同看法，指出地球上的语言可能会和飞船上的语言有所不同。阅读本文有利于开阔学生的视野。
1．What does Paragraph 2 mainly talk about？
A．Two American scholars.
B．Interstellar space exploration.
C．Language evolution on Earth.
D．The article by McKenzie and Punske.

语篇导读：本文是一篇说明文。文章主要介绍了太空旅行在2050年将变得受欢迎，目前日本和美国的各一家公司正在计划建设太空旅行服务项目。
解析：
1．is reported 考查时态、语态和主谓一致。句子是描述一般性事实，应用一般现在时，主语It和动词report之间是被动关系，应用一般现在时的被动语态，主语是第三人称单数，be动词用is。
2．is planning 考查时态和主谓一致。根据时间状语now可知，句子是现在进行时，又因主语为单数名词，故填is planning。
3．height 考查名词。结合空前的a可知，空处应用名词height。
4．flying 考查动名词。分析句子可知，空处作主语，应用动名词形式。
5．Although/Though/While 考查让步状语从句。结合句意可知，前后句之间是转折关系，应用although/though/while引导让步状语从句，位于句首首字母应大写。
6．cheaper 考查形容词比较级。结合句意及空前的much可知，空处应用形容词比较级。
7．an 考查冠词。hotel是可数名词，此处泛指“一家不同寻常的酒店”，应用不定冠词，且unusual发音是以元音音素开头，故填an。
8．neither 考查固定短语。neither...nor...既不……也不……，为固定用法。
9．normally 考查副词。此处修饰动词eat应用副词形式。
10．to make 考查动词不定式。结合句意可知，此处表示目的，应用动词不定式作目的状语。
