    Why do Americans struggle with watching their weight, while the French, who eat rich food, continue to stay thin? Now a research by Cornell University suggests how life style and decisions about eating may affect weight. Researchers concluded that the French tend to stop eating when they feel full. However, Americans tend to stop when their plate is empty or their favorite TV show is over.

    According to Dr. Joseph Mercola, a health expert, the French see eating as an important part of their life style. They enjoy food and therefore spend a fairly long time at the table, while Americans see eating as something to be squeezed (挤进) between the other daily activities. Mercola believes Americans lose the ability to sense when they are actually full. So they keep eating long after the French would have stopped. In addition, he points out that Americans drive to huge supermarkets to buy canned and frozen foods for the week. The French, instead, tend to shop daily, walking to small shops and farmers' markets where they have a choice of fresh fruits, vegetables, and eggs as well as high-quality meats for each meal.

    After a visit to the United States, Mireille Guiliano, author of French Women Don't Get Fat, decided to write about the importance of knowing when to stop rather than suggesting how to avoid food. Today she continues to stay slim and rarely goes to the gym.

    In spite of (尽管) all these differences, evidence shows that recent life style changes may be affecting French eating habits. Today the rate of obesity (肥胖)—or extreme overweight — among adults is only 6%. However, as American fast food gains acceptance and the young refuse older traditions, the obesity rate among French children has reached 17% — and is growing.

阅读下面的文言文,完成下列小题。

    韦睿,字怀文,京兆杜陵人也。事继母以孝闻。睿内兄王橙、姨弟杜恽,并有乡里盛名。伯父祖征谓睿曰:“汝自谓何如橙、恽?”睿谦不敢对。祖征曰:“汝文章或小减,学识当过之;而干国家,成功业,皆莫汝逮也。”

    后东宫建,迁太子右卫率,出为辅国将军。四年,王师北伐,诏睿都督众军。睿遣长史王超宗、梁郡太守冯道根攻魏小岘城,未能拔。睿巡行围栅,魏城中忽出数百人陈于门外,睿欲击之,诸将皆曰:“向本来,未有战备,徐还授甲,可进耳。”睿曰:“不然。。魏城中二千余人,闭门坚守,足以自保,无故出入于外,必其骁勇也,若能挫之,其城自拔。”众犹迟凝,睿指其节曰:“朝廷授此,非,韦睿之法,不可犯也。”乃进兵。士皆殊死战,魏军果败走,急攻之,中宿而城拔。

    睿于故旧,无所遗惜,士大夫年七十以上者,多与假板县令,乡里甚怀之。十五年,拜表仕,优诏不许。十七年,征散骑常侍、护军将军,寻给鼓吹一部,入直殿省。居朝廷,恂恂未尝忤视,高祖甚礼敬之。性慈爱,睿抚孤兄子过于己子。历官所得禄赐,皆散之亲故,家无余财。后为护军居家无事慕万石陆贾之为人因画之于壁以自玩。时虽老,暇日犹诸儿以学。第三子棱,尤明经史,世称其洽闻,睿每坐,棱使说书,其所发植,棱犹弗之逮也。高祖方锐意释氏,天下成从风而化。睿位居大臣,不欲与俗俯仰,所行略如他日。
