1.The chief foods eaten in any country depend largly on what grows best in its climate and soil.
[队长提示]:depend...on ---依赖于
2.Over a very large number of trials,the probability of an event\'s occurring is equal to the probability what it will not occur.
[队长提示]:这句也不难。
一:trail---有“审讯,实验”的意思
[词组]be on trail ---在受审中,在实验中
by trail and error---反复实验,不断摸索
二:event
[词组] at all events/in any event ---无论如何,不管怎样
in the event --- 结果,到头来
in the event that/of --倘若,万一
三:occur
[固定结构]:it occurs to sb. that ...某人想起了...
[辨析]:occur,happen,take place
happen---指事先无计划、偶然地发生
take place--指事先安排、计划的发生
occur---指发生时,有计划无计划都行,它还有“存在出现”的意思
3.Most substance contract when they freeze so that the density of a substance\'s solid is higher than the density of its liquid.
[队长提示]:这句也不难。
一:substance ---物质,内容,要旨。
[搭配]:in substance=by and large 或on the whole--大体上
二: [形]dense(密)---[动]condense(浓缩)---[名]density(密度,浓度)
