Scientists are seeking new and creative ways to deal with climate change. As well as reducing our carbon dioxide sent into the air, scientists say we must remove the gas from the air to keep Earths temperature down.
One expert has now suggested pouring carbon dioxide into deep trenches (海沟), forming vast liquid lakes, Steve Goldthorpe, an energy analyst based in New Zealand, says the lakes could forever hold vast quantities of carbon dioxide. This is because once the gas reaches a depth of 3,000 meters it is denser (密度大) than water, meaning it naturally sinks to the seafloor.
“If liquid CO2 were to be placed in such a trench, it would be 7 per cent more dense than seawater and could remain forever as a lake of liquid CO2 on the ocean floor,” Mr Goldthorpe wrote in his paper, “the stored carbon dioxide could become solid over time, which would stop it mixing with ocean currents.”
Previously, experts have suggested burying the extra carbon dioxide deep underground, possibly in abandoned (废弃的) oil and gas fields. While first tests have shown that this method has potential, scientists are still unsure whether people would accept the fix.
Carbon dioxide lakes do form naturally in the cold, high-pressure depths of the ocean, but they are rare.
Researchers have previously given up the idea of ocean CO2 storage because it can make the water more acidic, which may affect ocean ecosystems. Mr Goldthorpe recognizes this in his paper, writing, “Any influence on deep ocean ecosystems would need to be examined.”
1.What is Goldthorpe’s way of fighting climate change?
A.To cut down carbon dioxide sent into air.
B.To make the most of the traditional ways.
C.To pour carbon dioxide deep into the ocean.
D.To dig a large lake for storing carbon dioxide.
2.According to Goldthorpe, CO2 could remain in the trench on condition that ________.
A.the trench has to be deep enough
B.CO2 must first be changed into solid
C.the trench has to be large enough
D.CO2 must first be taken to the seafloor
3.The previous idea of ocean CO2 storage has been given up because ________.
A.natural storing places rarely exist
B.many oil and gas fields will have to be abandoned
C.scientists are unsure whether people would accept the fix
D.there are concerns on possible damage to the ocean ecosystem
4.The last paragraph indicates that Goldthorpe’s attitude towards his project is _________.
A.doubtful B.cautious
C.disapproving D.determined

Every day it seems that people are coming up with new and innovative ways to use mobile devices like cellphones and smart phones. Researchers at Princeton University are looking for new ways to measure a person’s sense of wellbeing with mobile devices.
To gain a better understanding of how cellphones and other mobile devices can measure our sense of happiness, the research team conducted a study that was published recently in the journal Demography. To gather data for their study, the team created an application for mobile devices using the Android operating system.
Once the app was developed, the researchers invited people to download it and take part in their study. Over a three-week period, the research team was able to collect data from some 270 participants living in 13 countries.
Participants came not only from the United States, but also from other nations like Australia, Canada, China, France, Germany, Israel, Japan, Norway, South Korea, Spain, Sweden and the United Kingdom.
Over the course of the study, participants received occasional text questions from the researchers that asked “How happy are you?”. Along with recording their response, the app used the mobile device’s built-in GPS to keep track of the participant’s location.
The study participants were asked to rate their current state of happiness on a scale of zero to five. As they gathered data from the information collected through the application, the researchers then were able to create new methods that could help provide a better understanding of how our surroundings can influence our emotional well-being.
The researchers learned that mobile devices can provide an effective way to quickly grab information that, because of today’s active lifestyle, can be difficult to record. Being able to quickly grab this information was something the researchers felt was important. They said feelings and emotions that were recorded as they were happening were most likely to be more honest and precise than using other methods like writing down how they felt on a piece of paper after the fact.
1.Which of the following statements is true according to the passage?
A. The study the team conducted has not been published yet.
B. About 270 people from 13 countries participated in the study.
C. The participants didn’t need to download the app to participate.
D. None of the participants came from the United Kingdom.
2.What did the researchers find vital as to rate people’s sense of happiness from the passage?
A. Recording people’s feelings and emotions quickly.
B. Writing down how they felt on a piece of paper.
C. Answering the text question “How happy are you?”
D. Knowing how the surroundings affect people’s happiness.
3.The underlined word in the first paragraph probably refers to ______.
A. emotion B. wealth
C. happiness D. technology
4.The best title of the passage is most likely to be “_______”.
A. People’s Sense of Happiness Related to Mobile Phones
B. Scientists Track Happiness with Cellphones
C. Methods to Rate People’s Happiness
D. A Better Understanding of People’s Sense of Happiness

5 Ways to deal with anxiety
Everyone has feelings of anxiety, nervousness, tension, and stress from time to time. Here are 5 ways to help manage them:
● Become a relaxation expert.
We all think we know how to relax. But chilling out in front of the TV or computer isn’t true relaxation. (Depending on what you’re watching or doing, it could even make you more tense.) The same is true for alcohol, drugs, or tobacco. 1.. What the body really needs is daily practice of a relaxation technique — like deep breathing, tai chi, or yoga — that has a physical effect on the mind. For example, deep breathing helps to relax a major nerve that runs from the diaphragm to the brain, sending a message to the entire body to let go and loosen up.
● Get enough sleep, and nourishment.
Want your mind and body to feel peaceful and strong enough to handle life’s ups and downs?
2.. Eat well: Choose fruit, vegetables, lean proteins, and whole grains for long-term energy (instead of the short bursts that come from too much sugar or caffeine).
● 3..
Spend time with friends or family. Organized activities are great, but just hanging out works too. Doing things with those we feel close to deepens our bonds, allowing us to feel supported and secure. And the fun and sharing that go with it allow us to feel happier and less upset about things. If you feel worried or nervous about something, talking about it with someone who listens and cares can help you feel more understood and better able to cope. You’ll be reminded that everyone has these feelings sometimes. You’re not alone.
● Get close to nature.
4.. (Choose somewhere you feel safe so you can relax and enjoy your surroundings.) Walking, hiking, trail biking, or snowshoeing offer the additional benefit of exercise. Invite a friend or two — or a family member — along and enjoy feeling connected to people as well.
● Pay attention to the good things.
A great way to keep our minds off the worry track is to focus our thoughts on things that are good, beautiful, and positive. 5.. Allow yourself to dream, wish, and imagine the best that could happen.
A. Connect with others.
B. Appreciate the small, everyday blessings.
C. There are many safe, drug-free remedies (补救措施) for anxiety
D. They may seem to relieve anxiety or stress, but it’s a false and temporary state of relaxation.
E. Get the right amount of sleep for your needs — not too much or too little.
F. Some start working right away, while others may help lessen anxiety over time.
G. Heading out for a walk in the park or a hike in the woods can help too.

What are the biggest problems that society will have to deal with in the new age? There are diseases like AIDS and cancer. There’s climate change, of course. And what about producing enough cheap food and energy for the world’s growing population? Who’s going to solve all these terrible problems? Yes, politicians and world leaders will have a big part to play. Yes, businesses will need to create the economic wealth to pay for some of these things. But who’s going to make a much greater difference to something like AIDS or climate change? It’s going to be a scientist. It is the scientist who can turn some new bit of science into a new technology to solve these problems.
If you like thinking about the world around you, why not become a scientist? It doesn’t mean you have to wear a white coat and plastic glasses and spend all your time in a lab as most people often imagine! Scientists do all kinds of amazing things that are actually interesting!
Military scientists develop not only new weapons but new military technologies that could help make wars out of date. Forensic(法医的) scientists work with the police to find quite small clues to catch criminals. Scientists work in schools and colleges as the teachers and professors who will train tomorrow’s scientists. Don’t think a scientist is far away! Maybe you like cooking? You could be a food technologist helping to keep fruit and vegetables fresher for longer. Perhaps sport is your thing? Do you know that most top athletes work with sports scientists in order to improve their performance? You could even be the science writer who gets to spend the life studying the latest advances and sharing them with the world.

We are naturally drawn to friends and colleagues with familiar voices, scientists have found.People prefer those who have a similar accent,intonation and tone of voice to themselves , they discovered.
Previous research has focused on how masculine or feminine a voice sounds.Men with deeper voices and women with slightly higher voices were thought to sound more attractive,because they suggest a bigger or a smaller body.
But the new study,published by a linguistics(语言学)expert in Canada,suggests there is a
more complex mechanism(机制)at play.Dr Molly Babel, from the University of British Columbia in Canada, said,“The voice is an amazingly flexible(灵活的)tool that we use to construct our identity.Very few things in our voices are changeless,so we felt that our preferences had to be about more than a person’s shape and size.’’
She recorded 30 volunteers’ voices and asked each to rate the others’ attractiveness on a scale of one to nine.Each participant was from western America,with similar accents.The people we assessed were all in the same dialect group,but they showed that dialect to different degrees.
“We seem to like people who sound like we sound,we like people who fit within what we know,”Dr Babel said.She also found that breathy voices in women-typified by the famous American actress Marilyn Monroe-were seen as more attractive.
The breathy tone,caused by younger and thinner vocal cords(声带),implied youthfulness
and health A creaky voice,suggesting a person has a cold,is tired or smokes,was seen as unattractive.The participants preferred men who spoke with a shorter average word length and deeper voices.
The linguist,whose work is published in the journal PLOS One,said,“Once you’re outside of a certain range of familiarity,novel and exotic sounding voices might become more attractive.We also have to keep in mind we find some accents more preferable than others because of social fixed ideas.”
1.In terms of voice preferences,the new findings highlight_______.
A.body size and shape B.shorter word length
C.thicker vocal cords D.the same social groups
2.Dr. Molly Babel mentions Marilyn Monroe in order to________.
A.evaluate a creaky voice
B.explain her new findings
C.challenge previous research
D.promote the actress’s reputation
3.According to the passage,who would most probably have a creaky voice?
A.An old lady with a silvery voice.
B.A young lady with a thin voice.
C.A deep-voiced man with a dry throat.
D.A little man with a quiet and gentle voice.
4.What can be inferred from the last paragraph?
A.People favor familiar accents when in a new place.
B.People might have a preference for different accents.
C.Voice preferences have no link to long-held belief.
D.Voice preferences are influenced by sex differences.
5.The main purpose of the passage is to________.
A.encourage men to use shorter words and talk less
B.inform readers of the findings of voices
C.argue against women’s breathy way of speaking
D.compare male voices with female voices
