答：show 可以跟that從句：
To indicate; register:The altimeter showed that the plane was descending.
這里不行,是因?yàn)閠hat后不成句.the changes of water use 是主語(yǔ),water use中use是名詞.
從句沒(méi)了謂語(yǔ).老師說(shuō)得沒(méi)錯(cuò),這里加that是錯(cuò)的,去掉就對(duì)了.shows 后跟the changes作賓語(yǔ).
老師可能沒(méi)有講清楚.但不是廢物.
樓主你題目也沒(méi)有打完整.
樓上別激動(dòng)! 中國(guó)很大,廢物老師教不過(guò)來(lái)的.網(wǎng)上答題,看到的人倒是蠻多的.
第一句話完整的是：In conclusion, the graph shows that the disease was increasingly prevalent until the 1980s when it was eradicated from Someland.應(yīng)該沒(méi)錯(cuò).佩服，你怎么知道第一句的完整？
