Passage　2
Whether　you　eat　to　live　or　live　to　eat,　food　should　help　keep　you　well.　In　our　modern　world　of　processed　and　preserved　foods,　many　nutritionists　(营养学家)　are　suggesting　that　we　can　stay　healthy　with　a　well-balanced　diet　of　plenty　of　fresh　fruits　and　vegetables　and　not　too　much　red　meat,　salt,　or　sugar.　In　fact,　eating　natural,　unprocessed　foods　that　are　made　from　scratch,　instead　of　artificial　and　junk　(假的)　foods,　may　not　only　keep　you　healthy,　but　save　your　money,　too.
To　stay　healthy,　you　must　also　be　careful　to　avoid　food　poisoning,　a　common,　unpleasant,　and　often　dangerous　illness　that　affects　one　out　of　every　six　Americans　each　year.　Food　poisoning　is　often　caused　by　salmonella　bacteria　(沙门化菌)　in　food,　especially　raw　meats　and　dairy　products.　Heat　usually　kills　the　bacteria,　and　refrigeration　keeps　them　from　growing.　So　remember　to　keep　hot　food　hot　and　cold　food　cold.　Also,　be　sure　to　keep　your　hands　and　cooking　utensils　clean　so　you　don't　transfer　germs　to　the　food　while　you　are　preparing　it.
If　you　use　canned　food,　always　check　the　cans　for　leaks　or　puffiness.　A　puffed　can　could　mean　botulism,　a　fatal　type　of　food　poisoning　that　you　cannot　see　or　smell.　Never　taste　any　food　that　you　suspect　has　spoiled.　Instead,　return　any　damaged　cans　or　spoiled　food　to　the　grocery　store,　and　the　manager　will　refund　(归还)　your　money.　When　using　processed　foods,　be　sure　to　read　all　the　labels　and　check　the　ingredients　and　the　freshness　date　before　you　buy　or　eat　the　food.
Eating　is　one　of　the　joys　of　life.　Being　careful　about　what　you　put　in　your　mouth　can　keep　it　that　way.

33.　E　of　Information　between　the　Sensory　(感观的)　Neurons　(神经)　and　the　Brain.　
The　sensory　neurons　keep　the　brain　informed　of　what　is　happening　outside　and　inside　the　body　through　a　variety　of　sensory　pick　-　up　units　called　receptors.　Some　of　these,　lying　at　or　near　the　skin　surface,　may　be　specially　sensitive　to　tissue　damage　(causing　pain),　or　light　contact　(producing　a　touch　sensation),　or　pressure,　or　temperature,　either　hot　or　cold.　Other　receptors　on　the　tongue　and　in　the　nose　respond　to　light　of　varying　intensities,　while　receptors　respond　to　color.　Receptors　in　the　ear　respond　to　minute　vibrations　caused　by　sound　waves　striking　the　eardrum.　Other　receptors　are　deep　in　the　walls　of　the　intestines;　when　the　intestines　contract　vigorously　because　of　the　presence　of　uncomfortable　food　or　gas,　these　receptors　transmit　signals　of　pain.　Still　other　receptors　lodged　in　the　muscles,　fire　off　signals　to　the　brain　any　time　a　muscle　contracts　or　a　joint　moves　or　is　subjected　to　added　pressure　or　tension.

The　disease　tends　to　occur　in　the　age　groups　over　40,　and　to　this　type　of　cancer　males　are　somewhat　more　likely　than　females.　In　many　cases　the　early　stage　of　growth　of　the　cancer　is　usually　not　associated　with　definite　symptoms.　By　the　time　symptoms　occur　to　an　intensity　that　makes　the　patient　seek　medical　advice,　the　cancer　is　often　found　to　have　spread　to　other　organs　such　as　the　liver.
