    Scientists say they now have proof to support the old-fashioned advice that it’s best to sleep on a problem．They say sleep strengthens the memory and helps the brain organize the masses of information we receive each day．
    The lead researcher Bob Stickgold at the Harvard Medical School said, “Sleep helps us draw rules from our experiences．It’s like knowing the difference between dogs and cats even if it’s hard to explain．”
    The US research team studied how well students remembered connections between words and symbols, reports New Scientist．They compared how the students performed if they had had a sleep between seeing the words and having the test, and if they had not slept．They found that people were better able to remember lists of related words after a night’s sleep than after the same time spent awake during the day．They also found it easier to remember themes that the words had in common．But they forgot around one in four more themes if they had been awake．
    Prof．John Groeger, of Survey University’s Sleep Research Centre, said, “People have been trying for years to find out what the purpose of sleep is, as we know that only certain parts of it have a restorative （促使康复的）value．”
    “We form and store huge numbers of experiences in the head every day, and sleep seems to be the way the brain deals with them all．”
    【小题1】The phrase “to sleep on a problem” in Paragraph 1 most likely means “________”．

    A．to pay full attention to a problem
    B．to wait until the next day for a decision
    C．to sleep to forget a problem
    D．to have difficulty in sleeping
    【小题2】In the study by the US research team, students were asked to ________．
    A．put together words of similar meanings
    B．remember words and their meanings
    C．show their knowledge of words
    D．make up lists of related words

    A．Themes learned right before the test．
    B．Rules from personal experiences．

    【小题4】What may be the importance of the research?
    A．It shows that sleep may help us manage information．

    The practice of students endlessly copying letters and sentences from a blackboard is a thing of the past. With the coming of new technologies like computers and smartphones, writing by hand has become something of nostalgic(怀旧的)skill. However, while today’s educators are using more and more technology in their teaching,many believe basic handwriting skills are still necessary for students to be successful-----both in school and in life.

    Virginia Berninger, professor of educational psychology at the University of Washington, says it’s important to continue teaching handwriting and help children acquire the skill of writing by hand.

    Berninger and her colleagues conducted a study that looked at the ability of students to complete various writing tasks----both on a computer and by hand. The study, published in 2009, found that when writing with a pen and paper, participants wrote longer essays and more complete sentences and had a faster word production rate.

    In a more recent study, Berninger looked at what role spelling plays in a student’s writing skills and found that how well children spell is tied to how well they can write. “Spelling makes some of the thinking parts of the brain active which helps us access our vocabulary, word meaning and concepts. It is allowing our written language to connect with ideas.” Berninger said.

    Spelling helps students translate ideas into words in their mind first and then to transcribe (转换) “those words in the mind written symbols on paper or keyboard and screen,” the study said. Seeing the words in the “mind’s eye” helps children not only to turn their ideas into words, says Berninger, but also to spot(发现) spelling mistakes when they write the words down and to correct them over time.

    “In our computer age, some people believe that we don’t have to teach spelling because we have spell checks,” she said. “But until a child has a functional spelling ability of about a fifth grade level, they won’t have the knowledge to choose the correct spelling among the options given by the computer.”

    1.What makes writing by hand a thing of the past? 

    A. The absence of blackboards in classrooms. 

    B. The use of new technologies in teaching.

    C. found that good essays are made up of long sentences. 

    D. discussed the importance of writing speed. 

    3.Which of the following best shows the role of spelling? 

    A. Spelling improves one’s memory of words. 

    B. Spelling ability is closely related to writing ability. 

    C. Spelling benefits the translation from words into ideas. 

    D. Spelling slows down finding exact words to express ideas. 

    4.What does “mind’s eye” in paragraph 5 mean? 

    A.  Window.     B. Soul      C. Picture.      D. Imagination. 

    5.What conclusion could be drawn from the passage 

    A. Computers can help people with their choice of words. 

    B. Spell checks can take the place of spelling teaching. 

    C. Handwriting still has a place in today’s classrooms.
