Most of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years, the planet was much colder than it is now .During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.
A new study from Switzerland throws light on where ice sheets(冰川)inched during the ice age. It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern regions.
This surprised the researchers from the University of Bern. Scientists have long assumed(假设)that most of the ice that melted was in the Northern hemisphere(半球)during the 30,000-year long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the Antarctic Ocean. It is easier for ice sheets to grow on land .If surrendered by sea the ice can easily just slip into the ocean instead of building up.
The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the Northern hemisphere that ice melted, there would have been a bigger impact(影响)on ocean currents (洋流)and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too. The only reasonable conclusion, the scientists could make, was that ice melted equally in the North and the South.
It is still a mystery as to what caused the temperature changes that caused the ice to melt.

Each year, backed up by a growing anti-consumerist movement, people are using the holiday season to call on us all to shop less.
Driven by concerns about resource exhaustion, over recent years environmentalists have increasingly turned their sights on our “consumer culture”. Groups such as The Story of Stuff and Buy Nothing New Day are growing as a movement that increasingly blames all our ills on our desire to shop.
We clearly have a growing resource problem. The produces we make, buy, and use are often linked to the destruction of our waterways, biodiversity, climate and the land on which millions of people live. But to blame these issues on Christmas shoppers is misguided, and puts us in the old trap of blaming individuals for what is a systematic problem.
While we complain about environmental destruction over Christmas, environmentalists often forget what the holiday season actually means for many people. For most, Christmas isn’t an add-on to an already heavy shopping year. In fact, it is likely the only time of year many have the opportunity to spend on friends and family, or even just to buy the necessities needed for modern life.
This is particularly, true for Boxing Day, often the target of the strongest derision(嘲弄) by anti-consumerists. While we may laugh at the queues in front of the shops, for many, those sales provide the one chance to buy items they’ve needed all year. As Leigh Phillips argues, “this is one of the few times of the year that people can even hope to afford such ‘luxuries’, the Christmas presents their kids are asking for, or just an appliance that works.”
Indeed, the richest 7% of people are responsible for 50% of greenhouse gas emissions. This becomes particularly harmful when you take into account that those shopping on Boxing Day are only a small part of our consumption “problem” anyway. Why are environmentalists attacking these individuals, while ignoring such people as Russian billionaire Roman Abramovich, who has his own£1.5bn yacht with a missile defence system?
Anyway, anti-consumerism has become a movement of wealthy people talking down to the working class about their life choices, while ignoring the real cause of our environmental problems. It is no wonder one is changing their behaviours—or that environmental destruction continues without any reduction in intensity.
1.It is indicated in the 1st paragraph that during the holiday season, many consumers .
A.ignore resource problems
B.are fascinated with presents
C.are encouraged to spend less
D.show great interest in the movement.
2.It can be inferred from Paragraphs 2 and 3 that the environmentalist movement .
A.has targeted the wrong persons
B.has achieved its intended purposes
C.has taken environment-friendly measures
D.has benefited both consumers and producers
3.The example of Roman Abramovich is used to show environmentalists’ .
A.madness about life choices
B.discontent with rich lifestyle
C.ignorance about the real cause
D.disrespect for holiday shoppers
4.It can be concluded from the text that telling people not to shop at Christmas is .
A.anything less than a responsibility B.nothing more than a bias
C.indicative of environmental awareness D.unacceptable to ordinary people

Many of us are used to hearing stories of people being pickpocketed in busy places. But most of us are aware of the dangers, so we are safe – at least, we think we are.
According to a BBC report, a growing number of thieves are trying to “hack (侵入) our mind’s weaknesses” to get their hands on our possessions.
“In fact, the key requirement for a successful pickpocket isn’t having quick fingers,” said the report. By using psychology, some pickpockets are taking advantage of the loopholes(漏洞) in our brains.
Our lack of ability to multitask is one of the most important loopholes used by pickpockets, the report explains. While this can often be a good trait(特点), allowing us to focus on the most important details in our surroundings, “a good trickster can use it against you, ” said neuroscientist Auzana Martinez-Conde.
“It’s all about directing people’s attention toward something else,” said James Brown, who studies the tricks of pickpocketing. Confidence, the power of suggestion, and certain hand movements such as moving your hands in an arc (弧形) are all said to be things that fool us.
Groups of pickpockets use a common trick designed to create a scene and confuse victims.
The first gang member, a “blocker”, walks in front of the victim and suddenly bumps into them. A second member of the gang then bumps into both of them from behind and stages an argument with the “blocker”. In the confusion, both men steal what they can and pass it to a third thief who quickly runs off with the stolen goods.
Some thieves go even further to exploit our psychology by hanging out near signs reading “beware of pickpockets”. Since this is one of the last places people expect to be robbed, many check where their valuables are, giving away their location to thieves.
But according to Brown, as long as we don’t daydream in public, we shouldn’t be worried.
“A street thief will avoid like the plague(瘟疫)” people who are demonstrating(展现)a very open awareness of their environment,” he said.
1.According to the BBC report, the main strategy of a successful pickpocket is________.
A. to distract victims
B. to give themselves multiple tasks to do
C. to focus on the most important details
D. to use swift hand movements
2.When groups of pickpockets use their common trick, ________.
A. it is the third thief’s task to steal what they can from the victim
B. the victim usually doesn’t dare to argue with them
C. the victim usually gets confused and lets down his or her guard
D. two members bump into the victim from different directions at the same time
3.Why do some thieves hang out near signs saying things like “beware of pickpocketers”?
A. They think it is more thrilling to steal in those areas.
B. Normally there are no police officers around.
C. They don’t know common people’s psychology.
D. They have a better chance of locating people’s valuables there.
4.According to James Brown, which of the following types of person is more likely to be pickpocketed?
A. People who look weak.
B. People who are walking slowly.
C. People who are absent-minded.
D. People who are alert to their surroundings.

The world consumes hundreds of billions of single-use plastic bags each year. They are difficult to recycle, wasteful and damage the nature. Environmental activists want to ban plastic bags or---as many communities have done ---charge a fee for them. But the plastic bag industry defends their use, saying people reuse plastic bags, and industry officials argue recycling is a matter of personal responsibility and should not be forced.
City officials say New Yorkers use 5.2 billion plastic bags each year. They are offered free with nearly every supermarket, or convenience store purchase. Many people like them, even if they sometimes feel guilty about using them. But what happens to those bags after they’ve been used in a huge environmental problem. They are found on beaches. They are caught in trees. They are swallowed by marine life.
Plastic bags are made of petroleum products and natural gas, and do not biodegrade (分解). And they are difficult to recycle. So New York City spends nearly $ 10 million dollars a year to send 100---thousand tons of plastic bags to landfills out of state.
In Washington, D.C., a five percent charge on all single-use bags led to about a 60 percent reduction and in Los Angeles County in California , a 10 cent charge on single-use bags led to a 95 percent reduction. With a 10 cent charge on bags, customers are much more likely to stop and think about whether they need a bag or not. And that’s really all that these laws are doing.
1.Who object to the limit of using plastic bags?
A. Plastic bag makers. B. Government officials.
C. Stores and supermarkets. D. Most of the consumers.
2.Paragraph 2 mainly tells us _____.
A. the difficulty about dealing with plastic bags
B. the popularity of plastic bags in New York
C. the great convenience brought by using plastic bags
D. the usage and problems of plastic bags in New York
3.What measure does the writer introduce to reduce the use of plastic bags?
A. Reducing the production of plastic bags.
B. Charging for the use of plastic bags.
C. Offering paper bags instead of plastic bags.
D. Making people realize the harm of plastic bags.

Most of us in China are used to paying for everything with our phones. 1. At least, this was the case for Lim Swee Say from Singapore, who found his first experience with Chinese payment methods quite impressive. Lim was waiting in line to buy nuts at a street stall (货摊) in Shanghai and saw other customers show their phones and take the nuts without giving cash. 2. It seems that Singapore falls behind in mobile payments. Some Chinese tourists find it inconvenient when they have to use cash in Singapore.
3. According to Xinhua News Agency, many countries now accept mobile payment services for Chinese tourists, with WeChat Pay covered in 13 overseas countries and regions and Alipay over 200. It’s now common to see the familiar green or blue logos in tourist destinations around the world, from a tiny shop in the Scottish Highlands to a huge department store in New York.
Mobile payments are now a normal part of life in China, and the trend is sweeping other nations. According to Forrester Research, in America, mobile payments rose by 37 per cent in 2016. 4.
This may be partly because western mobile payment services require businesses to install expensive equipment before customers can use them. 5.
A. He was trying to figure out how they got paid.
B. Foreign tourists don’t like to pay with their mobile phones.
C. But in China, all it takes is a QR code (二维码) and a phone.
D. Soon after, he realized that the customers were using WeChat Pay.
E. Still, Chinese mobile payments were nearly 50 times greater than those in the US.
F. But for foreign visitors who aren’t familiar with this method, it may seem strange.
G. The popularity of Chinese mobile payments has pushed some foreign companies to accept them.

Most of us have gone away from “mad men” in the street, only to realize that they are in fact using a Bluetooth headset. Now a new University of Pennsylvania study shows that muttering can actually help people find lost objects—in other words, saying the name of an object helps you find it more quickly.
Previous work has suggested that speaking aloud while performing step-by-step tasks, like tying shoelaces (鞋带), can help kids guide their behavior and let them focus on the job in hand. However, scientists were not sure if speaking aloud when performing tasks could help adults in the same way, especially when looking for particular objects. Professor Gary Lupan and Daniel Swingley, writing for the Quarterly Journal of Experimental Psychology, carried out some experiments. They hoped to give the fact that next time you lose your keys, muttering “keys, keys, keys” can in fact help you find them.
Inspired by viewing people muttering to themselves as they try to find things like peanut butter in a supermarket, the researchers conducted two experiments to see if this actually worked. In the first, participants were shown 20 pictures of various objects and were asked to find a certain one, with some seeing a text label (标签) telling them what they were looking for. These participants were then asked to search for the object again while saying the word to themselves, with results showing that saying it aloud helped people find the object more quickly.
The second experiment saw participants performing a shopping task, where they were shown photographs of items (物品) commonly found on supermarket shelves. They were asked to find all examples of a particular item, so if they were asked for apples they had to find all the bags of apples, as quickly as possible. The researchers found that there was also an advantage in saying the name of the product aloud when they were searching for something familiar.
The University of Pennsylvania study shows that muttering can actually help people reach the target object—in other words, muttering to oneself helps to focus the mind on something. It works more effectively than seeing a written description. Repeating the word over and over again helps even more.
1.The second paragraph tells us that ________.
A. muttering helps people to control their behavior
B. muttering has the same effect on both kids and adults
C. it is really hard to carry out the experiments on adults
D. it is easier for kids to do step-by-step tasks by muttering
2.According to the passage, muttering can help people in a way that ________.
A. it completely controls people’s mind
B. it directly explains people’s behavior
C. they concentrate more on their job at hand
D. they reduce their pressure from their mind
3.The two experiments mentioned in the passage show that ________.
A. participants were better at doing the shopping task
B. it took the participants the same time to find the objects
C. showing pictures of the items helped find them more quickly
D. participants saying aloud the word found the object more quickly
4.What is the best title of the passage?
A. Effects of Muttering
B. How to Find Lost Objects
C. What to Mutter to Yourself
D. Methods of Remembering Objects

Does every important present come in a big package? As the holiday season approaches, most of us are looking for the perfect gift, ready to give whatever we can afford, hoping to please the ones we love.
This morning, my son responded to my email, in which I had mentioned his Christmas list. To my surprise, he didn't tell me what was on his list—rather he opted to tell what was not, such as more sweaters or buttondowns.
“I have 3x more of shirts than I could ever possibly wear,” he wrote.
I laughed, not only at my silly assumption but also at the frank and sensitive way he'd told me I'd been missing the boat. In my attempts to be generous, I'd merely been repetitive.
It hurts to admit this naturally, but the truth is that if I'd been visiting him more frequently, I'd know he has too many shirts in his drawers with the tags still on them. But because he is living so far away, I just don't know what exactly he wears on a daily basis.
Perhaps if I paid him and his wife a visit, we could share takeout in their apartment. Laugh together. Talk about something. It would be a big gift in a small package, requiring only a plane flight and some time.
Of course, this present could come at any time of the year. I am thinking about the idea now because it's December, when thinking about perfect presents for those we love occupies our thoughts quite a bit. We are troubling ourselves with the idea of perfection, sometimes losing sight of the point of it all, which is simply to make one another happy.
So maybe under our Christmas tree this year there will be a package wrapped in red and green with my son's name on it. Inside will be a plane ticket to JFK in my name. Wouldn't that be perfect?
1.What did the author realize after reading her son's email?
A. Her son didn't think she was generous.
B. She ignored her son's inner feelings.
C. She missed out her son's development.
D. She didn't buy her son proper presents.
2.Which of following can best replace the underlined word “opted” in Paragraph 2?
A. Chose. B. Promised.
C. Refused. D. Pretended.
3.What might be the best title for the passage?
A. Small presents also count B. Presents—symbol of love
C. Big presents in little packages D. Presents—a bond between people

The holiday season is supposed to be the most festival and fun time of the year, but all those plans and expectations of joy can turn together and more stressful than they sound. This is especially true for those of us who struggle with mental illness.
1. Sometimes you’re forced to spend time with family you rarely see and don’t always get along with. Or you are off from work, with more time to think troubling thoughts. Or you are put into party situations that you don’t like.
When you have a routine, it is easier to manage whatever mental struggles you may face, and when that routine is broken, it can trigger things you may not be ready to face. 2. It was during the holidays that I hit a low moment and, with the help of my mother, decided to seek help for my eating disorder.
During the holidays, I often feel as if I were supposed to be everywhere with everyone.3. To fight this, I’ve developed a mantra (咒语): it’s not selfish to take time for yourself.
Take a walk in nature. Talk to a friend you trust. Sit out one of the holiday gatherings in favor of some personal time. 4.
Trying to spend all of your time pleasing everyone else is not only exhausting — it is impossible. And you know why? 5.
A.I know it has for me.
B.The holidays break your routine.
C.There are many things crowding in your mind.
D.I will accompany my friends to go wherever they like.
E.I have the added guilt of knowing it’s the season of giving.
F.Just do whatever helps you calm down and gives you a break from the stress.
G.If you take a little time for yourself, you will be a much better company for those around you.
