Strange events in the sky，such as speeding lights or flying objects，which cannot be explained are called UFOs.Some people believe they could be a sign of aliens.
Many people think there are intelligent life forms in the universe other than humans.However，millions of pounds have been spent searching for aliens and no one has found proof(证据).Some people think it is a waste of money and people’s skills.So，is searching for aliens worth the money and effort Here are two different voices.
阅读理解。
It’s a mystery that needs to be solved.“Are humans alone in the universe ” is a question that has inspired centuries of debate(辩论)，dating back thousands of years and at least as far as the ancient Greeks.It is a question that has inspired hundreds of books and films，which shows how important it is to people.If someone sees a UFO，we need to find out what it is.
Scientists searching for aliens could create new technologies and these could do good to the Earth.For example，the small，lightweight camera on phones was developed，so astronauts could take photos in space.Plus，if we were to discover aliens，we might be able to share knowledge with each other and create friendships across the universe.
★ There are many important problems here on Earth—such as climate(气候) change.People should focus energy on these rather than searching the universe for aliens that might not even exist(存在).Many people have spent lots of money trying to find signs of alien life and there is no result.Videos of flashing lights and strange objects in the sky might make good stories，but in fact there is probably a reasonable explanation，such as a dirty mark on the camera lens(镜头).Besides，if aliens do exist，they will probably find us first，so we might as well stop wasting our energy on them and spend it making the Earth a better place to live.
( )1.Paragraph 2 mainly focuses on __________.
A.what aliens are like
B.what people’s different opinions are

What happens when you mix fiction (based on the imagination) and science (based on 1 ) The result is “science fiction”.Science-based books and movies often take place in the 2 .Writers imagine what life will be many years from now.In science fiction，there is life on other 3 ，with aliens and monsters.People travel in spaceships，and there is lots of high 4 around.
完形填空。
Science fiction has many 5 kinds of plots (情节)，characters，and settings.Some of the first science fiction stories were about 6 aliens who try to take over the Earth and bring down the human race.Others were about people travelling in spaceships looking for 7 planets or keeping peace in the universe.The “science” was not very believable.
Usually，the technology in science fiction movies and books is ahead of its time.But sometimes，this technology is just too good to stay within the pages of a book.For example，robots appeared in science fiction before they existed in 8 life.
The 1960s Star Trek TV shows and later movies are full of more 9 .The giant view screen aboard the starship Enterprise looks very much like the flat TV screens of today.The crew used a small device to talk to each other on the ship.It even worked from the ship to the Earth.This hand-held device was very much like the future mobile phone.The small touch-screen the captain and soldiers 10 around was similar to a 21st century tablet or iPad.Today，science fiction is closer to scientific reality than ever before.

A.原因状语从句
在句中表示原因、理由的从句叫原因状语从句。
1.引导原因状语从句的从属连词主要有because，since，as。
2.表示语气的强弱顺序是：because > since > as。
3.这些连词都不能和so连用。
4.当原因状语从句位于句首时，通常要用逗号与主句隔开。
引导词 because
1.because强调明确直接的因果关系，回答用“why”来提问的问题。如：
She didn’t come to school because she was ill.她没来上学是因为病了。
—Why was he angry 他为什么生气
—Because I was late.因为我迟到了。
2.because从句可与for互换，但for是并列连词，连接的是并列句，并且在for前必须有逗号隔开。如：
We must start early because it will take us 3 hours to drive there.
=We must start early，for it will take us 3 hours to drive there.
我们要早点出发，因为开车去那儿要3个小时。
引导词since
1.since表示明摆着的理由或原因，常译为“既然”。如：
Since you have finished your homework，you can take a rest.
既然你已完成了作业，那可以休息一下了。
2.since还可引导时间状语从句，表示“自从……以来”。如：
We’ve known each other since we were children.我们从孩提时代起就相识了。
引导词as
1.as语气最弱，表示附带说明的原因。如：
As you’re busy，you needn’t go to see him today.因为你很忙，就没必要今天去看他了。
2.as还可引导时间状语从句，表示“当……的时候” “随着……”。如：
He dropped the glass as he stood up.他站起来时，把杯子摔了。
We get wiser as we get old.随着年龄的增长，我们也变得聪明些了。
B.because 与 because of 的区别
because和because of的意思都是“因为；由于”。但because是连词，其后接句子。because of是复合介词，其后接名词、代词、动名词、what从句等。如：
She doesn’t go to school because she is ill.
=She doesn’t go to school because of her illness.她没来上学是因为她生病了。

A conversation with a whale Some scientists teamed up and spoke to a humpback whale(座头鲸)named Twain.Their conversation took place after the scientists sent a “communication call” into the ocean off the coast of Alaska.The same call was made for 36 times over a 20-minute period.Each time，Twain called back.Professor Mc Cowan said that the research could make it easier to talk to aliens and better understand what aliens’ intelligence might be like.
_______________________ Scientists use technology to train dolphins to learn more about the ocean. They put small sensors(传感器) on dolphins.These sensors can get information about water temperature，saltiness and ocean flows.Then the sensors send the information to scientists right away for study.Dolphins swim well and have great senses.With the help of technology，they become good helpers for studying the ocean.
Sharks help to find seagrass areas Scientists have discovered the world’s largest known field of seagrass.They did it by using videos shot by some unusual helpers：tiger sharks.Seagrass can help clean the ocean’s water.But seagrass in the deep ocean is hard to find.The researchers tied cameras to the fins of seven tiger sharks.The cameras were designed to fall off after a few hours and float on the surface.The scientists were left with hours of videos taken as the sharks travelled for miles over the sea floor.
