　　新概念四的课文的问题!

　　Asithappens,arazorthatissafeinEuropeisunlikelytoelectrocuteAmericans.So,askbusinessesonbothsidesoftheAtlantic,whyhavetwolotsoftestswhereonewoulddo?Politiciansagree,inprinciple,soAmericaandtheEUhavebeentryingtoreachadealwhichwouldeliminatetheneedtodouble-testmanyproducts.TheyhopetofinishintimeforatradesummitbetweenAmericaandtheEUonMay28TH.Althoughnegotiatorsareoptimistic,thedetailsarecomplexenoughthattheymaybehard-pressedtogetadealatall.

　　1：中whyhavetwolotsoftestswhereonewoulddo?为什么有个LOTSOF?是什么意思?

　　2：课文中为什么都是用WOULD而不是WILL?

　　TheAmericanswouldhappilyreachoneaccordonstandardsformedicaldevicesandthemhammeroutdifferentpactscovering,say,electronicgoodsanddrugmanufacturing.TheEU--followingfinecontinentaltraditions--wantsagreementongeneralprinciples,whichcouldbeappliedtomanytypesofproductsandperhapsextendedtoothercountries.

　　这里面为什么也用WOULD还有COULD,用一般时态不行吗?
