4．Yawning sends out certain messages-either"Oh，this movie is so boring"or"I probably need to get some sleep"．But did you know that a yawn can also help your brain to cool down when it is overheated？
A new study，led by a research team at Princeton University，has indicated that yawning could be the brain's natural way of regulating temperature．People yawn more often when the temperature outdoors is lower than their body temperature but are less likely to yawn when it is hotter outdoors，according to Sciencedaily．com．
The research team did an experiment on 160people，80in summer and 80in winter，to examine how often they yawned at different air temperatures．The study found that people yawned more often in winter than in summer．Scientists say that when the air temperature is lower outside the body，there is heat exchange between the overheated brain and the cool air．But when the air temperature is higher than or equal to the body，people are less likely to yawn because the hot air they breathe in will make the brain even hotter．
When people yawn，their jaw is also stretched，which increases blood flow and may also help cool the brain．
The study showed that the amount someone yawned could be related to the amount of time they spent outside．The longer they spent outside in summer，the less they yawned．Nearly 40percent of participants yawned within their first five minutes outside，but after that the percentage was reduced to less than 10 percent．
However，the result was the opposite in winter．The number of people who yawned increased when they spent more than five minutes outdoors．But the change was only slight compared to summertime．
According to Gallup，this is the first report to show that yawning frequencies change depending on season．This could help us to understand better the way our brains work．It may also help us understand the reason why frequent yawning can sometimes be a sign of brain disease．

47．The purpose of the experiment isC．
A．to prove people yawn in winter and in summer equally
B．to indicate brain can regulate temperature naturally
C．to find the frequency of people's yawning
D．to show the real reason why people yawn

A．longer outdoor summertime results in more yawns
B．yawning frequency changes with outdoor time
C．yawning frequency increases with outdoor time
D．longer outdoor wintertime leads to fewer yawns

B．when the hot air breathed in makes the brain hotter
C．when the air temperature is higher than the body

8．Many years ago，I owned a service station and roadhouse on the main road between Melbourne and Adelaide．
One very cold，wet night at about 3：30a．m，there was a （36）Dat the front door of our house．A young man，（37）Cfrom head'to toe，explained that he had （38）Dout of petrol about 30km up the road．He had left his pregnant （怀孕的） wife and his two children（39）Bat the car and said that he would hitchhike （搭便车） back．

The Energy Diet
How can I lose weight when every time I go on a diet，I'm so exhausted that I can barely make it through the day？So goes the complaint of many men and women who are concerned about being overweight．What many people don't realize is that a healthful weight-loss plan can actually boost your energy．The key is to eat smart．And then combine this healthful diet with some physical activity．Here are six pointers to get you started．
61．C
Consume too few calories and you'll have less energy，and decrease the amount of calories burned．"That's because one of the ways the body protects itself from starvation is to slow down its metabolism，"explains Dr．Donald Hensrud，a nutrition professor at the Mayo Clinic，in Rochester，Minn．So how many calories do you need to feel energized while also slimming down？A healthful weight-loss rate is roughly one-and-a-half pounds per week，and the calorie intake to achieve this depends on your age，weight，and activity level．
62．E
The key to keeping your energy level up when you diet is to eat balanced meals that supply all the nutrients you need．"Vitamins and minerals act like spark plugs，"explains Kristine Clark，director of sports nutrition at Pennsylvania State University．"They help release the energy in nutrient-rich food．"Try to follow USDA guidelines．They call for 6 to 11 servings per day from the bread，cereal，rice，and pasta group； three to five servings of vegetables； two to four of fruits； two or three of milk or cheese； two or three of meat，fish，or eggs．Avoid fried and creamy dishes，and keep consumption of sweets and desserts to a minimum．
63．F
When you go for five to six hours without food，the amount of fuel in your system starts to run low，and you begin to feel tired．Therefore，says Kristine Clark，it's important to eat at regular intervals to keep your energy up．If you exercise，it's important to make sure you have"fuel in the tank"before you head for the gym．Avoid eating a large number of calories at one time，since it's harder to control your total calorie intake，making weight gain more likely．
64．A
About 10% of women of childbearing age in the United States are iron deficient．Iron is essential for energy and endurance because it is a vital component of red blood cells，which carry oxygen to working muscles．"Fatigue and listlessness can be directly associated with too little iron，"says Frances Berg，a licensed nutritionist in Hettinger，N．D．The best sources of iron are meat，poultry，and some fish．Other sources：fortified cereals，dried beans，dried fruits，and peas．
 65．D
"I don't have the energy to exercise!"say many dieters．Indeed，a 1998 survey，developed in part by the Center for Sports Medicine at Penn State，found that over 70% of respondents cited"too tired"or"lack of energy"as key reasons to skip exercising．Yet exercise is exactly what these people need．And，lastly，don't try to do too much too soon．Consider breaking your exercise into small units．Instead of trying to do 30 minutes in one chunk，accumulate exercise in short bouts （一场，一回）every day by mowing the lawn，walking to work，or climbing stairs instead of taking an elevator．It won't be long before you reap （收获）the rewards．Imagine carrying a 15-pound sack of groceries around all day．Then think about how much more energy you'd have if you put that sack down．
