14.Terraforming (Earth-forming) other planets,also known as planetary engineering (行星工程),seems like a task still centuries away for mankind to accomplish.However,it is a vigorous topic that attracts both popular and scientific interest.Why should the possibility of terraforming other planets be studied when it may be centuries before we know enough to even decide if it's a good idea?
Mankind is getting more and more hard facts about other planets.The atmosphere of Venus has been explored; robots have surveyed the surface of Mars; Mercury,Jupiter and Saturn have been studied by spacecraft. Speculations have been answered;new questions have been raised,and enough hard data is right now becoming available to allow us to make the first attempt of planetary engineering.
In the past,people with excellent ideas about terraforming have kept them to themselves,or buried them in a desk drawer because they did not realize that anyone else was interested.But now,a wide circle of people has begun to do this kind of work.For instance,NASA funded a project on transforming Mars.
There are several strong reasons which demand that the possibilities of terraforming be studied carefully.First,it's an exciting idea of a possible future for human beings.Such thinking has a valuable role in providing options for our future directions.Secondly,the techniques of terraforming will also help contemporary technologies in weather and climate control.Thirdly,such study may assist us in detecting any possible existence of extraterrestrial(地球外的)intelligence and alien civilizations on other planets.
Though the mission is far beyond our reach at the moment,we should at least keep our options open.Through debate and study on this subject,the possibility of rebuilding other planets to make them suitable homes for people may come true some day in the future.

84.According to the context,what's the meaning of the word"Speculation"in paragraph 2?C
A.The act of discussing something with a group of people.
B.The act of studying and researching.
C.The act of guessing without knowing all the facts about something.
D.The acting of writing letters to a certain organization.
85.Why did people keep the idea of terraforming to themselves in the past?A
A.They thought no one else would show interest in the idea.
B.They gradually came to find the idea crazy.
C.They thought the idea would never come true.
D.They had few resources for further study on this topic.
86.Which is NOT the reason to support the study of terraforming?D
A.Even if we don't succeed in terraforming,such study may help us to better understand technologies such as climate and weather control.
B.Such study may explore a new direction of development for human beings.
C.Such study may enable us to find the lives on other planets.
D.As the resources on Earth are being drained,it's very urgent to study how to migrate to other planets.
87.What's the main idea of the article?B
A.It's highly possible that terraforming other planets will come true so we should increase investing in this program.
B.Even if the idea of terraforming other planets may take centuries to realize,we have many reasons to support such studies.
C.Terraforming other planets is the best option for human being's future.
D.More and more people are taking planetary engineering as their occupation.

2.Convincing people that your way is the best way is often very difficult---especially when you're not quite sure why they're saying no.Turn the tables on your conversation and convince people of your point of view.(36)D   And with the right methods,you can do it.
1.(37)BKnowing how to persuade people isn't just in words and body language-it's also in knowing the right time to talk to them.If you approach people when they are more relaxed and open to discussion,you will most likely achieve faster,better results.
2.Talk fast.People are more persuaded by a fast,confident talker than accuracy.Sort of makes sense-the faster you talk,the less time your listener has to process what you've said and question it.(38)E
3.Get to know them.A large part of whether or not persuasion is effective is based on the general understanding between you and your son/friend/employee.If you don't know the person well,it's necessary to start building this understanding immediately-find common ground as soon as possible.(39)GSo find parallels and make them known.
4.(40)AThere is something to be said for clarity.If you're confusing the person may want to agree with you,but doesn't necessarily know what you're looking for.Speaking in a firm way will help you maintain directness and keep your intentions clear.

A.Speak firmly.
B.Understand the best time.
C.Talk about what interests them.
D.The trick is to get them wondering why they're saying no.
E.Thus,you create the feeling that you truly grasp the subject.
F.If someone talks fast,it's the perfect time to persuade him.
G.Human,in general,feel safer around people that are similar to them.

2.The last time I saw him was 12 years ago.Twelve years has passed,and I still remember eating pomegranates (石榴) while his thin hands combed through my hair.To this day,I still remember stories my grandfather used to tell me.As a child living in Korea,my grandfathe r was my closest friend,the man I spent every day with and depended on for back rides.We were inseparable from the moment we awoke until I fell asleep in his arms.I ate the food he prepared,and he was my pillow and storyteller.Little did we know that a day would come when his first granddaughter would leave.My father was to be stationed in the United States and time would blur (使…變模糊) our images of each other.
