Li Hua发布：2025/1/1 15:0:2组卷：5引用：8难度：0.6596．From the moon to Mars，scientists have been hunting for alien life in the solar system for decades.
However，Venus was not regarded as an ideal place because of its hot temperature and dry atmosphere.But a recent discovery of traces of a gas in the clouds of Venus has excited astronomers，as it may serve as a potential sign of life.
On Sept 14，the Royal Astronomical Society of Canada announced that scientists have detected phosphine （磷化氢） in the clouds of Venus.Phosphine is a colorless，poisonous gas that has a smell of garlic.Though poisonous，it is viewed as a possible sign of life because on Earth the gas is made by microorganisms that live in oxygen-free environments.
"I was very surprised，in fact，" astronomer Jane Greaves of Cardiff University in Wales and lead author of the research，told MSN. "There is a chance that we have detected some kind of living organism in the clouds of Venus."
This layer of clouds is about 48 kilometers above the Venus surface，with its temperature ranging from 30 to 200 degrees Fahrenheit（about -1 to 93°C）.Scientists have concluded that if life exists on Venus，the clouds are likely the only place where it would survive.
Scientists went through every possibility that could have led to the formation of phosphine gas in Venus' clouds，including volcanoes，lightning strikes，small meteorites（陨石）falling into the atmosphere.But they ruled all of them out.It was concluded that there is no explanation for the existence of this gas in Venus' clouds，other than the presence of life，USA Today reported.
Although the detection of phosphine is not solid evidence for life，this finding is great enough to change scientists' view on Venus，which is thought to be a completely inhospitable （不适合居住的） planet.
（1）What is the text mainly about？
A．A newly detected gas may indicate possible existence of life on Venus.
B．Scientists found the best place on Venus for humans to live.
C．The environment on Venus changed in favor of life.
D．Phosphine formed on Venus means alien life is present.
（2）What can we learn about phosphine from the text？
A．It has no smell at all.
B．It only exists on Venus.
C．It can be produced by microorganisms.
D．It is a sign of the existence of oxygen.
（3）What can we infer from paragraphs 4 and 5？
A．Various living organisms have been detected on Venus.
B．The higher the cloud is above Venus，the warmer it is.
C．The clouds are rich in phosphine.
D．If life exists on Venus，it is likely in the clouds.
（4）What did scientists conclude about the phosphine gas detected on Venus？
A．It could be formed as a result of the falling of meteorites.
B．It could be a sign that there is life in Venus' clouds.
C．It could be caused by volcanoes and lightning strikes.
D．It proves that Venus is another habitable planet.发布：2025/1/1 15:0:2组卷：6引用：2难度：0.7597．How to Speak in Public Many people have a fear of public speaking.They worry that they will lose their tongue，bore the audience or somehow make a fool of themselves.It is easy to try to avoid public speaking，but that usually doesn't work out.Everyone has to speak publicly at some point in their life.You may give a speech in a class or a meeting.Maybe you'll have to give a speech for some honor you've received.（1）
Relax.（2）Your audience don't expect you to be perfect.They want you to succeed just as much as you do.If you're thinking you'll forget everything，remind（提醒）yourself that you are prepared and knowledgeable.Imagine yourself doing well.
Be jye.airself.You are not Jack Can field or Tony Robbins.Share your true personality with your audience，and they'll find you reliable.（3）
Know your topic.Try to speak about the subject you know well.Research the topic to make sure that you are correct.Public speaking is easier when you don't feel like a fraud（骗子）.
（4）Choose your message for the group you are speaking to carefully.If you're giving a public speech，then rude jokes certainly won't be suitable.
Give value.Base your speech on 2 or 3 main points.（5）They'll be satisfied if they leave with something they can use，and that is what public speaking is all about.
A.Know your audience.
B.Choose some serious messages.
C.Don't force yourself to be perfect.
D.Don't focus your attention on too many points.
E.Pretend to be someone that you're not，and they'll discover it.

发布：2025/1/1 15:0:2组卷：30引用：2难度：0.8600．You're asleep on a Saturday morning when the sound of an alarm clock erupts from your device.You turn over to see the word SNOOZE projected in the air above your device.You reach out and touch the virtual button with your finger-a slight feeling on your fingertip-before falling back to sleep.
Researchers from the University of Tsukuba in Japan are working on a technology that could make this possible.Led by associate professor Yoichi Ochiai，the team creates shapes in the air using a laser（激光）that releases short pulses（脉冲）of light.The high-intensity light can break down air molecules（分子），which produces short-lived spots of light.The system polishes images by rapidly adjusting the central point of the laser in three dimensions.
A previous version of the technology used nano-second laser pulses，which have the unfortunate side effect of burning human skin.Ochiai' s system，named Fairy Lights，employs much shorter laser pulses that are much less dangerous despite having a high peak intensity，Ochiai says.The tiny hearts，stars and fairies that the system projects are not only safe to touch，but they are sensitive to contact.In one test，the system projects a checkbox that can be filled in with your finger. "It feels like sandpaper or a mild electric shock， " Ochiai says.
Ochiai also predicts large-scale emergency monitors that could be projected high over a city to wan residents about a natural disaster or direct them toward an escape route.While the initial images were not large，Ochiai says the flexibility of the system depends on the size and power of the equipment used.Large systems are currently expensive，he says，adding that technologies that draw images will likely become more achievable over the next 10 to 20 years as the multi-million-dollar price decreases.
（1）What is the author's purpose of writing paragraph 1？
A．To describe a scene of sleep-in.
B．To promote a high-tech alarm clock.
C．To explain the function of a project.
D．To introduce the use of a new technology.
（2）What can we infer from paragraph 2？
A．Images can be projected in the air.
B．Shapes can be released by pulses of light.
C．The system can be adjusted in three dimensions.
D．Air molecules can be broken down in a short time.
（3）What do we know about Fairy Lights？
A．It projects images safe to touch.
B．It brings benefits to human skin.
C．It employs nano-second laser pulses.
D．It becomes sensitive to electric currents.
（4）According to paragraph 4，Ochiai might agree that.
A．The technology will be put in use in a decade or two
B．The technology can accurately predict natural disasters
C．The system can inform people of a safer escape route
D．The more flexible the system is，the larger the image will be发布：2025/1/1 15:0:2组卷：8引用：2难度：0.7
