5．The children ________ many times not to swim in the river．（　　）
A．toldB．have toldC．have been toldD．are being told

分析 孩子們已經(jīng)被告知很多次不要再合理游泳．

解答 答案是C．本題考查現(xiàn)在完成時．現(xiàn)在完成時可以表示反復(fù)發(fā)生的動作，常常與several times、many times等時間狀語連用；由題干中的many times推斷用完成時，并且孩子們是被告知，故選C．

點評 對時態(tài)的選擇，要在把握時態(tài)的基本用法的基礎(chǔ)上，根據(jù)具體語境和題干中的時間推斷時態(tài)，同時關(guān)注特殊的結(jié)構(gòu)．

16．Intense physical exercise is not the only way to better health．Studies show that walking several times a week can lower the risk of many diseases．They include heart disease，stroke，diabetes，bone loss，arthritis （關(guān)節(jié)炎），and depression．Walking also can help you lose weight．Fast walking is good for the heart．It lowers the blood pressure．It raises the amount of good cholesterol （膽固醇） in the blood．Researchers say walking can sharply reduce the risk of suffering a heart attack．
Studies have also shown that walking for 30 minutes a day can delay and possibly prevent the development of diabetes．People who are overweight have an especially high risk of developing this disease．
Walking strengthens the muscles and builds up the bones that they are attached to．Studies show that walking could decrease the risk of developing osteoporosis （骨質(zhì)疏松癥）．Walking can also help ease the pain of arthritis in areas where bones are joined．This is because walking strengthens the muscles around the bones．
Experts say walking is one of the safest ways of exercise．There is a low risk of injuries．So it is good for people who are starting an exercise program for the first time and for older people．
A walking program is easy to start．You should wear loose clothes and good shoes．There are shoes that are designed especially for lots of walking．
How fast should you walk？For the best effect，doctors say you should walk fast enough to cause you to breathe hard．Yet you should still be able to talk．Let your arms move freely while you walk．
There are no rules to starting a walking program．You might walk short distances．Or you might walk up hills to strengthen your leg muscles．Health experts say you can gain the most from a walking program if you walk at about five kilometers an hour for 30 minutes a day．You should do this about five times a week．
