最值钱的宝贝     

T·V·帕德玛  庞启帆 《中华活页文选(初中版)》2014,(11):23-25

霍尔沃与他的母亲住在比约斯托大森林附近的一间小屋里。为了维持母子俩的生活,霍尔沃的母亲从早到晚都在缝制衣服。她的手掌因此结满了老茧,她的视力也因长期在昏暗的灯光下工作而降低了。她只有一件破旧的羊毛披肩,在冬天缝制衣服时,经常冷得发抖,不停咳嗽。霍尔沃憎恨自己年龄太小而帮不上母亲的忙。冬夜,看到母亲的身体在微微颤抖,霍尔沃说：＂妈妈,我长大后,一定要赚很多很多的钱。到那时,我会给你买很多很多衣服,  相似文献

变成木乃伊升降机到三楼时没停,贾森从里边伸出手,我一把抓住。升降机继续往二楼跑,但我的一只胳膊、头和一半肩膀都在三楼。“帮帮我!”贾森对贾尼丝和卡拉喊。三个人合力把我拉了出来,只差一点儿我就要掉下去了。我缓过气来,说:“快离开这里,有人看见我进了升降机。”事实上我已经听见脚步声了。我们四个人跨进走廊,拼命地跑,想离那脚步声远一点,再远一点。我手里还拿着电筒,但背包落〔là〕在馆长办公室了。面前又出现一道门,后面的脚步声越来越响。“我们不能总这样跑。”贾尼丝说。“今晚恐怕出不去了,不如找个地方先躲起来。”我说。…  相似文献

Pedometer reliability, validity and daily activity targets among 10- to 15-year-old boys     

Jago R  Watson K  Baranowski T  Zakeri I  Yoo S  Baranowski J  Conry K 《Journal of sports sciences》2006,24(3):241-251

The aims of this study were to: (1) determine whether the number of pedometer counts recorded by adolescents differs according to the adiposity of the participant or location on the body; (2) assess the accuracy and reliability of pedometers during field activity; and (3) set adolescent pedometer-based physical activity targets. Seventy-eight 11- to 15-year-old Boy Scouts completed three types of activity: walking, fast walking and running. Each type was performed twice. Participants wore three pedometers and one activity monitor during all activities. Participants were divided into groups of normal weight (BMI < 85th percentile) and at risk of being overweight (BMI > or = 85th percentile). Intra-class correlations across the three activities indicated reliability (r = 0.51 - 0.92, P < 0.001). This conclusion was supported by narrow limits of agreement that were within a pre-set range that was practically meaningful. Multivariate analysis of covariance indicated adiposity group differences, but this difference was a function of the increased stature among the larger participants (P < 0.001). Ordinary least-squares regression models and multi-level regression models showed positive associations between the number of pedometer and activity monitor counts recorded by the three groups of participants during all activities (all P < 0.001). The mean number of counts recorded for all participants during the fast walk was 127 counts per minute. In conclusion, the pedometers provided an accurate assessment of adolescent physical activity, and a conservative estimate of 8000 pedometer counts in 60 min is equivalent to 60 min of moderate to vigorous physical activity.  相似文献   

Does exercise motivation predict engagement in objectively assessed bouts of moderate-intensity exercise? A self-determination theory perspective     

Standage M  Sebire SJ  Loney T 《运动与训练心理学杂志》2008,30(4):337-352

This study examined the utility of motivation as advanced by self-determination theory (Deci & Ryan, 2000) in predicting objectively assessed bouts of moderate intensity exercise behavior. Participants provided data pertaining to their exercise motivation. One week later, participants wore a combined accelerometer and heart rate monitor (Actiheart; Cambridge Neurotechnology Ltd) and 24-hr energy expenditure was estimated for 7 days. After controlling for gender and a combined marker of BMI and waist circumference, results showed autonomous motivation to positively predict moderate-intensity exercise bouts of >or=10 min, or=20 min, and an accumulation needed to meet public health recommendations for moderate intensity activity (i.e., ACSM/AHA guidelines). The present findings add bouts of objectively assessed exercise behavior to the growing body of literature that documents the adaptive consequences of engaging in exercise for autonomous reasons. Implications for practice and future work are discussed.  相似文献
