We have many different was of coping with the cold.We can put on more clothes, stay next to a fireplace, turn on the air conditioner or simply travel to a warmer city to spend the winter.But things are not as easy for plantsnlike humans, plants can’t move to escape the cold or generate heat to keep themselves warm.So how do they manageurvive the freezing winter?
The cold is a big challenge for plants.Teir living tissues can be damaged when they freeze.t's like a plant's equivalent(相等物)frostbite(冻疮).Also,the pcess of freezing and thawing(解冻)can causer bubbles to form in the plant's water transport system.f enough of these air bubbles come together as water thaws they can block the flow of water from the roots to the leaves and kill the plant.
To live through cold weather,plants have develop three strategies,Se plants,ch as oak trees, avoid freezing damage by dropping their leaves, before the winter chill sets in-effectively shutting off the flow of water between roots and leaves—and growing new leaves and water transport cells when the warm spring returns. Other plants, pine trees for example, protect them-selves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.The third stratef;yi8 also the most extreme.Some plant; die on the ground in winter and start growing as new plants from seeds when conditions get warmer.
Howeer, these smart strategies were developed nmry8lowly-over millions of years of evolution.This eads scientists to worry that plants may not be able to deal with human-caused climate change, which has only started occurring over the past few decades.Scientists are hoping o find possible ways to save plants from the threat of climate change.

It is a tall tale that terrifies most young children. Swallow a piece of chewing gum and it will
remain in your body for seven years before it is digested. An even worse tale is that swallowed
gum can wrap itself around your heart.
But what does happen if you should accidentally eat a stick of gum? Chewing gum is made
out of gum base, sweeteners, coloring and flavoring. The gum base is pretty indigestible—it is a
mixture of different ingredients (成分) that our body can't absorb.
Most of the time, your stomach really cannot break down the gum the way it would break
down other foods. However, your digestive system has another way to deal with things you
swallow. After all, we eat lots of things that we are unable to fully digest. They keep moving
along until they make it all the way through the gut (肠子) and come out at the other end one or
two days later.
The saliva (唾液) in our mouths will make an attempt at digesting chewing gum as soon as
we put it in our mouths. It might get through the shell but many of gum's base ingredients are
indigestible. It's then down to our stomach muscles—which contract and relax, much like the
way an earthworm moves—to slowly force the things that we swallow through our systems.
Swallowing a huge piece of gum or swallowing many small pieces of gum in a short time can
cause a blockage within the digestive system, most often in children, who have a thinner digestive
tube than adults—but this is extremely rare.

B.It will be eventually moved out of our body.
C.It will fight against the power of the gut.

Telling fewer lies benefits people physically and mentally. Anita Kelly, study author and professor of psychology at the University of Notre Dame, employed 110 adults for her study. She divided them into two groups and asked one group to stop lying for 10 weeks. Lies included big ones and tiny ones—any false statements—but participants were still allowed to leave out the truth, keep secrets and avoid questions they didn't want to answer, etc. The other group wasn't given any special instructions about lying.
It turns out that both groups reduced their lying, but those who were specifically told to tell the truth improved their health more. “We found that the participants could purposefully and dramatically reduce their everyday lies, and that in turn was associated with significantly improved health,” said Kelly.
When participants in the nolie group told three fewer white lies than they did in other weeks, they experienced, on average, fewer mentalhealth complaints and physical complaints. They were less likely to feel tense or sad and also experienced fewer sore throats and headaches. They also reported that personal relationships improved.
Additionally,
participants found themselves honest about their daily accomplishments, and they stopped making up excuses for being late or failing to complete a task, for example.
“It's certainly a worthy goal to have people be more honest and interact with others in a more honest way,” says psychologist Robert Feldman. “That would be beneficial, I'm a little doubtful whether it makes us all healthier, but it may make us healthier in a psychological way.”

A.told as many lies as before
B.were almost equally healthy
C.tended to lie less about their activities
D.experienced tenser personal relationships
答案:C 细节理解题。根据第二段的第一句“It turns out that both groups reduced their lying...”可知,答案C符合文义。

A.white lies might make people have more complaints
B.honesty is likely to help people become mentally healthier
C.people should not be honest with others but with themselves
D.telling the truth can make people physically and mentally healthy
