New findings suggest that brainy card games such as contract bridge may temporarily(临时地) raise production of a key blood cell including in fighting off illness. After 90 minutes of play, bridge players had increased levels of immune(免疫) cells, according to the research reported last week.
A researcher, Diamond, studied bridge players from a women’s bridge club. She chose bridge players because the game includes skills stimulating(刺激) a part of the brain called the dorsolateral cortex. Earlier animal research suggests that this part of the brain may play a role in the immune system.
The findings are based on blood samples drawn from 12 women players. Their blood samples showed a rise in levels of white blood cells called T cells after they played bridge for 90 minutes. T cells are produced by the thymus gland(胸腺) and used by the immune system against diseases.
The T cell count jumped significantly in eight of the bridge players, and slightly in the other four. The findings contribute to the field of neuroimmunology(神经免疫学), whose name reflects the fact that the nervous system and the immune system are not considered separate and isolated(独立的) systems. What isn’t clear is whether the help to the immune system from an activity like contract bridge is lasting or temporary. It is also not clear whether the increase in T cells could finally be targeted against special illnesses.

of their own. The student who is writing a composition, the businessman who is writing a report, and the housewife who is preparing a talk for a woman`s club often need the kind of information they find in an encyclopedia. But no one wants what he writes to read as it were copied from an encyclopedia. What you write should read as if it came from you. 2. Even if you have every intention of rewriting the material in your own words, it is unwise to copy twice-first when you are reading and second when you are using your notes. It is easy to copy a paragraph without being sure of what it means. But to make a note expressing the meaning of a paragraph in your own words requires you to prove to yourself that you have understood that paragraph. Note-taking also helps you to remember what you have read. It is much easier to remember what you have said in a note that someone else has said in a book. Even if author`s vocabulary is easily understood, it isn`t the vocabulary you naturally think of. Putting his ideas into your vocabulary makes those ideas yours, and yours are the ideas you best remember. 4. For example, a sentence note on the paragraph above might be “Notes help you remember.”A topical note for the same paragraph might be “Notes as memory helps”. Both of these are four-word notes, and therefore either has an advantage to save time at the moment of note-taking 5. writing that you will do. Notes that make you think as you write are better than notes that merely help you remember information. The thinking writer is the one who creates something new, something that no one can point to and say, “Oh, I have seen that same paragraph in an encyclopedia.” |
