affected by asian monsoons(季风)，but monsoons are difficult to predict.american researchers have put together a 700year record of the rainy seasons，which is expected to provide guidance for experts making weather predictions.every year，moist (潮湿的)air masses，known as monsoon，produce large amounts of rainfall in india，east asia，northern australia and east africa.all this wet air is pulled in by a high pressure area over the indian ocean and a low pressure area to the south.according to edward cook，a weather expert at columbia university in new york，the complex nature of the climate systems across asia makes monsoons hard to predict.in addition，climate records for the area are too recent and not detailed enough to be of much use.therefore，he and a team of researchers spent more than fifteen years traveling across asia，looking for trees old enough to provide longterm records.they measured the rings，or circles，inside thousands of ancient trees in more than 300 places.rainfall has a direct link to the growth and width of rings on some kinds of trees.the researchers developed a document they are calling a monsoon asia drought atlas.it shows the effect of monsoons over seven centuries，beginning in the 1300s.professor cook says the treering records show periods of wet and dry weather.“if the monsoon basically fails or is a very weak one，the trees affected by monsoons at that location might put on a very narrow ring.but if the monsoon is very strong，the trees affected by that monsoon might put on a wide ring for that year.so，the wide and narrow ring widths of the chronology that we developed in asia provide us with a measure of monsoon variability.” with all this information，researchers say they can begin to improve computer climate models for predicting the behavior of monsoons.“there has been widespread famine and starvation and human dying in the past in large droughts.and on the other hand，if the monsoon is particularly heavy，it can cause extensive flooding，” said eugene wahl，a scientist with americas national oceanic and atmospheric administration.“so，to get a sense of what the regional moisture patterns have been，dryness and wetness over such a long period of time in great detail，i would call it a kind of victory for climate science.”1whats the passage mainly about?athe effects of asian monsoons.bthe necessity of weather forecast.cthe achievements of edward cook.da breakthrough in monsoon prediction.2it is difficult for experts to predict asian monsoons because_.ait is hard to keep longterm climate recordsbthey are formed under complex climate systemscthey influence many nationsdthere is heavy rainfall in asia3what can be inferred from the passage?along and detailed climate records can offer useful information for monsoon research.bthe monsoon asia drought atlas has a monsoon record for about 1,300 years.cthe trees affected by monsoon grow fast if the monsoon is weak.dthe rainfall might be low although the monsoon is strong in monsoonaffected areas.4what do we know about the research according to eugene wahl?ait is a great achievement in climate science.bit should include information about human life in the past.cit has analyzed moisture models worldwide.dit will help people prevent droughts and floods.5which of the following best describes the tone of this passage?amatteroffact. bpessimistic.chumorous. dfriendly.bkids will often ignore your requests for them to shut off the tv，start their chores(杂事)，or do their homework as a way to avoid following your directions.before you know it，youve started to sound like a broken record as you repeatedly ask them to do their assignments，clean their rooms，or take out the trash(垃圾)rather than saying “do your chores now”，youll be more effective if you set a target time for when the chores have to be completed.so instead of arguing about starting chores，just say，“if chores arent done by 4 pm，here are the consequences.”then its up to your child to complete the chores.put the ball back in their court.dont argue or fight with them，just say，“thats the way its going to be.” it shouldnt be punitive(惩罚性的) as much as it should be persuasive.“if your chores arent done by 4 pm，then no video game time until chores are done.and if finishing those chores runs into homework time，thats going to be your loss.”on the other hand，when dealing with homework，keep it very simple.have a time when homework starts，and at that time，all electronics go off and do not go back on until you see that their homework is done.if your kids say they have no homework，then they should use that time to study or read.either way，there should be a time set aside when the electronics are off.when a kid wears his ipod or headphones when youre trying to talk to him，make no bones about it；he is not ignoring you but disrespecting you.at that point，everything else should stop until he takes the earplugs out of his ears.dont try to communicate with him when hes wearing headphoneseven if he tells you he can hear you.wearing them while youre talking to him is a sign of disrespect.parents should be very tough about this kind of thing.remember，mutual respect becomes more important as children mature.6according to the passage，it seldom happens that _.akids turn a deaf ear to their parents requestsbparents directions sound like a broken recordcchildren are ready to follow their parents directionsdparents are unaware of what they are repeating to their kids7parents will be able to deal with their children more effectively if they _.aavoid direct ways of
