In the past，man did not have to think about the protection of his environment．There were few people on the earth，and natural resources seemed to be unlimited．Today things are different．The world has become too crowded．We are using up our natural resources too quickly，and at the same time we are polluting our environment with dangerous chemicals．If we continue to do this，human life on the earth will not survive．
Everyone realizes today that if too many fish are taken from the sea，there will soon be none left．Yet，with modern fishing methods，more and more fish are caught．We know that if too many trees are cut down，forests will disappear and nothing will grow on the land．Yet，we continue to cut down more and more trees．We realize that if rivers are polluted with waste from factories，we will die．However，in most countries waste is still put into the rivers or the seas and there are few laws to stop this．We know，too，that if the population of the countries is rising at the present rate，in a few years，there will not be enough food．What can we do to solve these problems？
If we eat more vegetables and less meat，there will be more food for everyone．Land that is used to grow crops can feed five times more people than land where animals are kept．

2．There' s no place like home.It' s the place where we' re surrounded by our possessions and creature comforts.We purchase things to give our homes a personal touch.And one thing we're buying more of is houseplants.But are these "living" additions to our homes good for us and the environment？
Houseplants，also known as pot plants，add a natural touch and they have the ability to brighten up a room on a budget.The Royal Horticultural Society found that nearly 72% of adults in the UK had a houseplant in their home，with this figure rising to 80% of 16-24 year olds.A fifth of owners also said they use plants in the home to boost their health and well-being.And average sales last year were up on the previous year.
It seems millennials （千禧代） are driving the growth in the sales of houseplants.More young people are living in flats without a garden.24-year-old Daisy Hale said "being able to care for something but not having too much commitment—I guess that's a classic millennial line—is ideal for my lifestyle."
From hanging baskets，to cacti （仙人掌） and succulent ferns，the choice of vegetation is endless.They are easy to care for，and there have been unproven claims that they improve the air quality in our home.But whatever their benefits，there are now concerns that they might not be so good for the environment.Some are bought online and shipped from overseas.Fay Kenworthy，co-founder of PlantSwap，a community activity that encourages people to trade plants locally，said "this could defeat many local plants."
But botanist James Wong argues that home delivery has less of an environmental impact than multiple trips to the garden center in a car.Although he' s not too concerned about the environmental impact，others are worried about the plastic pots they are in and the type of peat （泥炭） that some of them are grown in.However，a sustainable approach to buying them may be the best way forward if we want to introduce some natural greenery into our homes.
（1）What is the benefit of a houseplant？
A．A houseplant can cure people of many diseases.
B．A houseplant is ideal for millennials' career.
C．A houseplant improve the water quality in our home.
D．A houseplant can beautify a room with little money.
（2）Which of the following may Fay Kenworthy agree with？
A．The choice of vegetation is endless.
B．People should buy local plants.
C．It's best to buy plants online.
D．Houseplants are hard to care for.
（3）Where is the passage probably from？
A．A fashion magazine.
B．A tour brochure.
C．A scientific fiction.
D．A history book.
（4）What is James Wong's attitude towards home delivery of plants？
A．Negative.
B．Neutral.
C．Positive.
D．Not mentioned.
（5）What is the best title of the passage？
A．Natural Greenery.
B．Millennials' Choice.
C．Houseplants：Good or Bad？
D．Hanging Baskets or a Garden？發(fā)布：2025/1/1 13:0:1組卷：1引用：2難度：0.5 -
3．Why Walking Makes You a Better Worker？ We're busy at work，distracted （分） by technology and often live in urban environments far from wild spaces．（1）
The average American，for example，spends about 90% of their life indoors．But what happens if we make time for an hour outside each day？
（2）You'll have to stand up and move，which is beneficial if most of your day involves sitting in front of a screen．Research shows short breaks can improve work enthusiasm，and a quick break in natural light will deliver a shot of vitamin D．
There's also a lot of work on the mental benefits of being in nature-on the state of being happy and on your brain's ability to make sense of life． "When people are all out in nature，even in urban nature，people tend to have more positive emotion and energy than when they are indoors．（3）says Lisa Nisbet ，associate professor at Canada's Trent University．
The idea that nature is good for us has been gaining ground since the 1980s．（4）Afterwards shinrin-yoku，the Japanese concept followed that absorbing the atmosphere in forests can benefit your health．Researchers of shinrin-yoku have since found plenty of physical and mental benefits，while global studies suggest time in nature can，for example，restore our ability to focus，increase creativity，and even help us live longer．
Of course，many of us live in cities with no ready access to forests or wilderness．（5）Various studies have shown that green environments in cities have beneficial effects．
A．We also don't get out much．
B．But it doesn't have to be a forest．
C．People can get to a forest for a hike．
D．In other words，people are happier in nature．
E．There are some obvious benefits to going outside．
F．Green and blue spaces are better than busy city streets．
