It’s never a real problem for us when the weather gets 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 – people have many different ways of dealing with the cold.

But things are not as easy for plants. Unlike humans, plants can’t move to escape the cold or generate heat ( 发热) to keep themselves warm. So how do they manage to survive the freezing winter?

It turns out that plants have their own strategies （策略） too, said a study published on Dec 22 in the journal Nature.

According to researcher Amy Zanne of George Washington University, US, the cold is a big challenge for plants. Their living tissues （活组织） can be damaged when they freeze. “It’s like a plant’s equivalent to frostbite ( 相当于冻疮),” Zanne told Science Daily. Also, the process of freezing and thawing (解冻) can cause air bubbles （气泡） to form in the plant’s water transport system. “If 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,” she explained.

To live through cold weather, plants have developed three traits （特性） , according to the study. Some plants, such as oak trees（橡树）, 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（松树） for example, protect themselves by narrowing their water transport cells, which makes it easier for cells to travel among air bubbles.

The third strategy is also the most extreme – some plants die on the ground in winter and start growing as new plants from seeds when conditions get warmer.

However, the study also found that these smart strategies were developed very slowly – over millions

of years of evolution （进化）. This leads 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 that this study can help people find possible ways to save plants from the threat

of climate change.

1.What is the article mainly about?

A. Why plants are not afraid of the winter chill.

B. The ways that plants survive cold weather.

C. Changes in plants’ water transport system in winter.

D. How plants evolve to keep up with climate change.

2.According to the article, if a plant freezes in the winter, ______.

A. it produces more living tissues to stay alive

B. its leaves quickly fall out and its roots begin to die

C. lots of air bubbles form in its water transport system

D. its water transport system could be blocked in the spring

3.What are scientists worried about when it comes to plants according to the article?

A. Plants may not be able to adapt to the increasingly cold climate.

B. Human activities might have a great impact on the pace of plants’ evolution.

C. Plants may not be able to evolve fast enough to adapt to human-caused climate change.

D. The strategies plants develop are not good enough to protect them against cold.

My grandmother was always encouraging me to set goals and work hard to achieve them. She would tell me not to be a follower and not to set ________on what I could achieve. She ________ believed that there were no limits that you could ________ whatever you wanted. I would never forget the following story that she once told me：A farmer won first ________at the country fair for his huge radish (小萝卜)that was the exact shape and ________of a milk bottle. Many were ________as to how the farmer was able to grow this radish that was the exact shape of a milk bottle. ________ one gentleman went up to the farmer and asked the question. The farmer replied，“It was ________. I got the seed growing and then I put it into the milk bottle. It had ________else to go.”You can use this story as an analogy (比喻) to life－our lives are________ by the kind of surroundings we place ourselves in, the people that we allow to________ us, and the goals we give ourselves.If we only________ and take no action, then we get no further. But if we ________，set a goal and take action, then our life takes a________ shape.

Goals and actions can help us accomplish more in a year than what some people will accomplish in a lifetime. To prove this________ ，read the biographies of ________ people and you will see that goals and actions________played a big role in their success.

Remember the________ of Mary Kay Ash, who said，“Don't limit yourself. ” Many people limit themselves to what they think they can do. You can go ________ your mind lets you. Whatever you believe, remember, you can achieve.”

However wealthy we may be, we can never find enough hours in the day to do everything we want. Economics deals with this problem through the concept of opportunity cost, which simply refers to whether someone’s time or money could be better spent on something else.

Every hour of our time has a value. For every hour we work at one job we could quite easily be doing another, or be sleeping or watching a film. Each of these options has a different opportunity cost—namely, what they cost us in missed opportunities.

Say you intend to watch a football match but the tickets are expensive and it will take you a couple of hours to get to and from the stadium. Why not, you might reason, watch the game from home and use the leftover money and time to have dinner with friends? This—the alternative use of your cash and time—is the opportunity cost.

For economists, every decision is made by knowledge of what one must forgo—in terms of money and enjoyment—in order to take it up. By knowing precisely what you are receiving and what you are missing out on, you ought to be able to make better-informed, more reasonable decisions. Consider that most famous economic rule of all: there’s no such thing as a free lunch. Even if someone offers to take you out to lunch for free, the time you will spend in the restaurant still costs you something in terms of forgone opportunities.

Some people find the idea of opportunity cost extremely discouraging: imagine spending your entire life calculating whether your time would be better spent elsewhere doing something more profitable or enjoyable. Yet, in a sense it’s human nature to do precisely that we assess the advantages and disadvantages of decisions all the time.

In the business world, a popular phrase is “value for money.” People want their cash to go as far as possible. However, another is fast obtaining an advantage: “value for time.” The biggest restriction on our resources is the number of hours we can devote to something, so we look to maximize the return we get on our investment of time. By reading this passage you are giving over a bit of your time which could be spent doing other activities, such as sleeping and eating. In return, however, this passage will help you to think like an economist, closely considering the opportunity cost of each of your decisions.

1.According to the passage, the concept of “opportunity cost” is applied to ________.

A. weighing the choice of opportunities

B. reducing missed opportunities

C. making more money

D. taking more opportunities

2.The “leftover ... time” in Paragraph 3 probably refers to the time ________.

A. taken to have dinner with friends

B. spared for watching the match at home

C. saved from not going to watch the match

D. spent on the way to and from the match

3.What are forgone opportunities?

A. Opportunities you make up for.

B. Opportunities you forget in decision-making.

C. Opportunities you give up for better ones.

D. Opportunities you miss accidentally.

4.What is the author’s attitude towards the concept of “opportunity cost”?

A. Indifferent B. Negative

C. Subjective D. Objective

Last year, A Bite of China, made by CCTVs Documentary Channel, sparked discussion not only on Chinese food, but also on locally made documentary programs.

With fascinating footage（影片片段） and stories, documentaries encourage us to think about interesting issues we wouldn’t necessarily know about.

So, what makes a good documentary, and what should we pay attention to when we watch one? Here, we offer a few easy strategies to help you get the most out of watching documentaries.

Pay attention to the themes

While watching a documentary, keep your eyes and ears peeled for the themes people talk about and what ideas they focus on. Is it meant to be informative or raise a certain emotional response?

Think critically

Listen to what the people in the documentary are saying and ask yourself the following questions If you were debating with someone or introducing a new concept, would you say the things the people in the documentary are saying? Do the arguments make sense?

Check the sources

If you’re sitting at the computer and can’t think of anything to do, why not look up the points the documentary made and see if they are accurate? You could even read more about what is presented in the documentary.

Who are the creators?

The creators or financial backers of a film will usually be involved with how the subject matter is presented. For instance, as the documentary 2016 Obama’s America was directed in large part by a conservative writer, it’s not surprising that it’s critical of President Obama from the beginning.

1.Which of the following is the most proper to describe documentaries?

A. non-fictional B. controversial

C. subjective D. thoughtful

2.The passage is mainly written to ______.

A. inform us of factors of good documentaries.
