阅读下列材料回答 材料1 “九五”期间,我国粮食产量突破5亿吨大关,基本实现了总量平衡,丰年有余。但农民人均收入增幅连续,四年持续下降,去年仅比上年增2%,为4年来增幅最低。 党的十五届五中全会通过的《建议》和九届全国人大四次会议通过的《纲要》都把增加农民收入放在非常突出的位置,这在党的决议及五年计划中都是首次。 材料2 影响农民增收的因素很多,其一,我国粮食产量五年连续丰收,产量大幅提高,但优质粮不多,还要靠进口,种植品种也比较单一。其二,农业生产力水平低,分散的小农经营格局,使劳动产品转化为商品的程度比较低。其三,城镇化水平低,无法吸纳剩余劳动力,多余劳动力靠种地不可能增收。其四,乱收费现象严重,农民不堪重负。 (1)阅读材料1,联系所学知识说明党中央国务院为什么高度重视农民增收问题。 (2)针对材料2涉及影响农民增收的原因,请你为农民增加收入提些建议。
