Secure your home with these expert-advised home safety tips that turn burglars into 1osers.

◆Pay attention to bathroom windows
Burglars are often people you’ve seen before，like a serviceman working on your house.If a yard worker or unknown visitor uses the bathroom，he may open the window so he can gain entry later.4..
◆Join in a community-wide crime prevention program

The conclusion of the Paris Agreement in 2015，in which almost every nation committed to reduce their carbon emissions(排放)，was supposed to be a turning point in the fight against climate change.But many countries have already fallen behind their goals.Meanwhile emissions worldwide continue to rise.
The only way to catch up is to aggressively pursue an approach that takes advantage of every possible strategy to reduce emissions.Wind and solar energy are usually part of this effort，but it must also include investing heavily in carbon capture(碳捕捉)，utilization(应用)and storage(CCUS)—a range of technologies that pull carbon dioxide from the air，and transform it into useful materials or store it underground.Although CCUS has been opposed as too expensive and unproved，recent gains have made it far more effective.Improvements such as chemical compounds could drive the cost down from $1 00 per ton of captured carbon in 20 16 to $ 20 per ton by 2025，according to a 2016 article in Science.
Three primary CCUS paths lead to the reduction of carbon emissions:retrofitting(改装)existing power plants；reducing emissions in industries that cannot run on renewable energy；and directly removing carbon from the air.Cutting emissions from existing electric power stations with CCUS could be made more appealing in a future with a circular carbon economy，in which captured carbon could be resold and recycled for other uses——for instance，serving as a raw material for making concrete or plastics.
The basic idea of carbon capture has faced a lot of opposition.Skepticism has come from climate change deniers，who see it as a waste of money，and from passionate supporters of climate action, who fear that it would be used to justify continued reliance on fossil fuels.Both groups are ignoring the recent advances and the opportunity they present.By limiting investment in decarbonization，the world will miss a major avenue for reducing emissions in a variety of industries.CCUS can also create jobs and profits from what was previously only a waste material by creating a larger economy around carbon.
The transition to clean energy has become necessary.But that transition’s ability to achieve deep decarbonization will become less effective without this wide range of solutions，which must include CCUS.
1.What can CCUS technologies do in reducing emissions?
A. Closing down existing power plants.
B. Limiting investment in heavy industry.
C. Processing raw materials underground.
D. Turning carbon dioxide into useful materials.
2.Why is it attractive to retrofit existing power plants with CCUS?
A. It can remove carbon directly from the air.
B. It can benefit the industry economically.
C. It is the most affordable way to capture carbon.
D. It helps power plants produce concrete or plastics.
3.What can be inferred from paragraph 4?
A. Fossil fuels will be no longer used in future.
B. Investing in decarbonization is a worthwhile project.
C. Climate change deniers believe in the necessity of decarbonization.
D. Little progress has been made in the fight against carbon emissions.
4.What can be a suitable title for the text?
A. Capture That Carbon B. Let Carbon Go
C. Stand Firm with Energy Protection D. Say Goodbye to Energy Crisis
“At almost any given age，most of us are getting better at some things and worse at others，”Joshua Hartshorne，an MIT cognitive(认知的)science researcher and the lead author of a study looking at how intelligence changes as we age，told Business Insider.His team quizzed thousands of people aged 10—90 on their ability to do things like remembering lists of words，recognizing faces，learning names，and doing math.Their results suggest that no matter your age，there’s almost always a new peak on the horizon.
The human brain has a remarkable capacity to recognize and identify faces，and scientists are just beginning to learn why.On average，we know that our ability to learn and remember new faces appears to peak shortly after our 30th birthday.
Having trouble focusing? The study suggests that our ability to maintain attention improves with age，reaching its peak around age 43.While younger adults may excel in the speed and flexibility of information processing，adults approaching their mid-years may have the greatest capacity to remain focused.
Dating is tough.One of the reasons could be that we’re generally bad at reading other people’s emotions until we reach our late 40s.That’s according to one component of Hartshorne’s study，which involved showing thousands of people images of faces cropped tightly around the eye area.Participants were asked to describe the emotion the person in the photo was feeling.Performance peaked for people aged around 48.
Many people believe that their math skills decline after they leave school and stop practicing arithmetic.But the next time you try to split up a check，keep this in mind:your ability to do basic subtraction and division doesn’t reach its apex until your 50th birthday.
Ever wonder why you always lose at Scrabble? Good news:Your best days may be ahead.According to people’s scores on multiple—choice vocabulary tests，most of us don’t reach our peak wordsmithing abilities until we’re in our late 60s or early 70s.
1.What did the scientists mainly test during the research?
A. Communication ability. B. Athletic ability.
C. Intelligence ability. D. Reading ability.
2.What does the underlined word“apex”in paragraph 5 mean?
A. Destination. B. Top. C. Goal. D. Minimum.
3.Who is most likely to succeed according to the text?
A. Lucy，72，trying to win at Scrabble.
B. Tom，26，trying to identify strangers’ faces.
C. Jack，48，trying to focus his attention for a long time.
D. Lily，43，trying to read the emotions in different eyes.
4.What does Hartshorne’s study mainly tell us?
A. There is no end to learning.
B. Constant dropping wears away the stone.
C. Genius is nothing but labor and diligence.
D. A foot may prove short while an inch may prove long.
