① It is easy to believe that the daily life of a plant is simple and boring. They seem to just stand there and sunbathe. In fact, plants are always busy doing many things. Measuring (估量) light is one of them. This activity helps plants to plan better for the future.

② To start with, we should know how plants feel the light. In fact, there are some special proteins (蛋白质) in their cells (细胞). Once receiving light, they will call on other cells to produce, resulting in the growth towards the light.

③ Then what can plants get from measuring the changes in the amount of daylight? This helps them to tell what time of the year it is. If a plant is beginning to get more daylight, it knows it’s spring. Because of this, it may then start producing flowers.

④ If the amount of daylight starts to get low, the plant knows that autumn is coming. It may start to store “food” for its growth. For example, the potato plant will make tubers(块茎)—the potatoes that we eat.

⑤ Plants record not only the amount of daylight they receive, but also the quality of light. Some forms of light can help plants grow better. Direct sunlight, for example, works better than light that is being separated through the leaves of other plants. A plant can’t get the right form of light when it is prevented from getting light by other plants. It may then begin to grow taller or produce larger leaves in order to get more sunlight.

1. What is one of a plant’s daily activities according to Paragraph 1?
A.Producing flowers.B.Taking in CO2.
C.Sleeping in the sun.D.Measuring light.
2. What is the theme (主题) of the passage?

3. What is the best title for the text?
A.Plants Tell SeasonsB.Plants “See” Light
C.Plants Need “Food”D.Plants Sunbathe Daily

【推荐1】以下是一篇短文,请阅读全文,并从下列的六个句子中选择五个还原到原文中,使原文的意思完整、连贯。

I developed a habit of daily learning something new many years ago. It’s one of the best things I’ve ever done.     1     And it also gives me a deeper understanding of how the world works.

    2     When we learn something new, our brain forms new neuronal (神经元的) connections. The more we learn, the easier it is for us to get knowledge. The brain is like a muscle.     3    

Learning new things can also improve our skills, such as creative writing, math and many others we’ll find helpful now and in the future.

Understanding new information helps us develop our critical (批判性的) thinking skills. When we’re studying a new subject, our brain actively processes new information.     4     Knowing different knowledge also helps us to avoid believing fake (假的) information on the Internet. Even when you are just writing a book report, you are training your mind to become more analytical (善于分析的).

By learning something new, we can have interesting conversations with our friends.     5     Next time you meet your friends, share some of the information that you’ve learned and discussed it. This will give you a deeper understanding of the topic you are trying to know more.

【推荐2】Language students often think they have memory problems. They worry because they can’t remember words. In fact, the problem usually isn’t with their memory. The problem is with how they study.

To remember words better, you need to understand how memory works. There are two kinds of memory: short-term and long-term. When you see, hear, or read something, it goes first into short-term memory. But short-term memory lasts for only a few seconds. You will only remember something longer if it goes into long-term memory. Your long-term memory is like a very big library with many, many books. And like a library, it’s organized(有条理的).When you put away a book-or memory-you can’t just leave it anywhere. You have to choose a place where you can find it again.

How can you do this with vocabulary? The answer is to work with the word and think about the word in new ways. You can do this by writing new sentences that include it. Even better, you can invent a little story about the word, with people or places that you know. Another way is to make a picture in your mind with the word. For example, if the word is height, you can think of the tallest person you know and try to guess his or her height. All of these activities are good ways to think about words. They make the meaning of words stronger in your long-term memory. And they give a way to find a word when you need it.

【推荐3】Do you dream about a trip to the space one day? Seeds (种子) of some vegetables and crops are a lot luckier than you, as they have travelled to space and back.

China is among the three countries in the world that carry out agricultural research (农业研究) in space. The others are Russia and the US.

Since 1987, China has sent about 1,000 species of seeds into space. These include green peppers (青椒), tomatoes, cucumbers (黄瓜), carrots, lettuce and wheat. Even on China’s first manned spaceship Shenzhou V, there were some seeds from an island.

“Conditions in outer space such as radiation (辐射) and low gravity can cause big changes in the seeds,” said Chinese researcher Jin Xing.
