    It's never a real problem for us when the weather gets cold. We can put on more clothes, stay next to a fire place 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 run from the cold or produce heat to keep themselves warm. So how do they manage to live in the freezing winter?

    Actually plants have their own ways too.

    According to researcher Amy Zanne, the cold is a big challenge for plants. Their living tissues(活组织) can be hurt when they freeze. "It's like a plant's frostbite(冻疮)," Zanne told Science Daily. Also, the cold can cause air bubbles(气泡)to form in the plant's water system. "If enough of these air bubbles come together, they will be harmful to the plant," she explained.

    To live through cold weather, plants have developed three ways, according to the study.

    Some plants, such as oak trees, avoid frostbite by dropping their leaves before the winter comes, which can shut off the flow of water between roots and leaves, and they grow new leaves and water transport cells when the warm spring returns.

    Other plants, pine trees for example, protect themselves by making their water transport cells thinner, which makes it easier for cells to travel among air bubbles.

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

    However, the tudy also found that these smart ways were developed over a very long period of time. This causes scientists to worry that plants may not be able to deal with human – caused climate change(气候变化), which has only started recently.

    Scientists are hoping that this study can help people find possible ways to save plants from the danger from climate change.

(1)、According to the passage, why is the cold a challenge for plants?
A、Because they are only grown in warmer places. B、Because they can't live without leaves. C、Because there's no water for plants. D、Because the living tissues can be easily hurt.
(2)、We can infer from the passage that ________.
A、pine trees' calls can become thinner B、some plants can't live in winter if they don't produce seeds C、climate change can change the way plants live D、there are already ways to save plants from climate change
(3)、If we put the passage into three parts, which of the following is the best?

(①=Para.(自然段)1 ②=Para.2 ③=Para.3 ④=Para.4 ⑤=Para.5……)

A、①②/ ③④⑤⑥⑦/ ⑧⑨⑩ B、①②/ ③④⑤⑥⑦⑧/ ⑨⑩ C、①②③/ ④⑤⑥⑦/ ⑧⑨⑩ D、①②③/ ④⑤⑥⑦⑧/ ⑨⑩
(4)、Which is the best title for the passage?
A、Take action to deal with climate change! B、Help save plants! C、Plants are losing the ability to save themselves! D、Humans will live without plants soon!

Answer the questions (根据短文内容回答下列问题)

    In the time it takes you to read this sentence, the population of the Earth will have grown by 10 people. That may not sound much, but it is about 14,000 people an hour. That is the same as adding most of the population of Germany to the world every year!

    Most of these new people are born in developing countries. These countries are found in much of Africa, South America, and parts of Asia. In the developed countries of Europe and North America, the population is growing very slowly. This is because women in these countries have, on average, only one or two children. In the developing countries, many women have five or more children. In 1950, around one quarter of the world's population lived in the developed countries. By 2050, these countries will be the home to only around one tenth of the world's people.

    In the developing countries, more than one billion people already live below the poverty line (贫困线).These people don't have enough food to eat and they live in poor housing; children get little or no time at school and suffer from many kinds of diseases.

    The United Nations (UN) tries to guess population growth. At the beginning of the 21st century, the world's population was around six billion people. The UN has said that the world's population will level off at 12. 5 billion people by the year 2100. Other people think the world's population will continue to grow, reaching 14 billion people before it becomes stable or even falls.

    There are many different kinds of disasters around the world. As an adult you know what to do during a disaster, but what about the children? Some adults think it would probably never happen to them, so they don't teach their children what to do. Before it's too late, here are ways to help you prepare your children for a disaster.

    Educate: It is always good to let your children know about possible disasters. This doesn't mean children have to live in fear. When teaching them about disasters, keep the conversation positive (积极的) by telling them there is a solution (解决办法) to the disaster. Keep the conversations short, allow for questions and answer them honestly.

    Prepare: Always be prepared. And that is the best piece of advice for children. For example, when preparing for bad weather, get the tools you need, like candles, radios, food, water and medicine. Teach your children what is needed in certain disasters so that they know what is available for them, if ever needed.

    Plan: You should always have a plan for you and your children for any dangerous situation. Write out a simple list that they can read. The plan could start with "listen to an adult's advice and/or call 119".

    Practise: Once you have got the correct safety tools and worked out the right plan, practise every few months. Practising what to do during a disaster with your children will help them if the time comes.

    Disasters can't be avoided but they can be lessened once you are prepared and ready for one.
