　　Healthy eating

　　One in five Britons “never eat at the table”

　　More than one in five Britons never eat at the table and 85 per cent admit to snacking mindlessly, a new research suggested.

　　People regularly fail to think about what they are eating and many are piling on the pounds as a result, it showed.

　　Of the 85% who admitted to “unconscious eating”， most said boredom was the main trigger(诱因)(59%)．

　　Eating to give themselves a treat was the second most common reason(41%) followed by feeling depressed(36%)．

　　TV watching came in fourth place as a trigger for unconscious eating(35%), while snacking in a bid to cheer themselves up came in fifth (25%)．

　　More than 60% of adults surveyed admitted to eating too much, despite 75% saying they wanted to lose weight.

　　Obesity expert and GP(General Practitioner)Ian Campbell said: “Being aware of what and how much we eat is essential to weight management”．

　　“Too often people get the balance wrong—the key to a healthy balanced diet is to be mindful about our eating.”

　　have sb. doing＝allow/tolerate(sth.) 表示允许/容忍(某事物)发生。此处的have是使役动词，用在否定句中，特别是用在will not,cannot等之后。意为“使某人做某事”时，多用于肯定句中。

　　①I won't_have_you_doing such a thing.

　　我不允许你做这种事。

　　I can't_have_you_speaking to your mother like that.

　　①You have 30 seconds to_answer the question.

　　(1)(2011·陕西，14)Clare had her luggage________an hour before her plane left.

　　A．check

　　B．checking

　　C．to check

　　D．checked

　　答案：D　考查非谓语动词作宾语补足语。句意：克莱尔在飞机起飞一个小时之前让人检查了行李。分析句子结构可知，本题考查“have＋宾语(her luggage)＋宾语补足语”， her luggage承受check这一动作，所以用其过去分词形式。

　　(2)I can't have you________ill of my good friend.

　　A．to speak

　　B．speaking

　　C．speak

　　D．spoken

　　答案：B　句意：我不能容忍你说我好朋友的坏话。句中have sb. doing表示“容忍；允许”之意，常用于否定句中。

　　(3)(2008·全国)The director had her assistant______some hot dogs for the meeting.

　　A．picked up

　　B．picks up

　　C．pick up

　　D．picking up

　　答案：C　考查非谓语动词。“在have＋宾语＋宾补”的句式中，若宾补为动词，可构成have sth. done; have sb. do sth.(此时have相当于make)；或者have sb. doing sth.“听任某人干某事”。由句意不难看出C正确。
