• 9、介词顺口溜 in 在……里，out在……外， 在旁边的是beside，靠近的为by。 on在……上，under在……下， above在上头，below在底下。 10、be的用法歌 动词be，变化大，“I”用“am”“You” 用“are” Is用于它（it）、他（he）、她（she），复 数一定要用“are”， 切莫用错闹笑话。
• 15、基数词变序数词（之一） 基变序，有规律，词尾字母tdd。① 八减t，九减e，f要把ve替。② ty把y变成i，记住山前有个e。③ ① 指first、second、third。 ② 指eight去掉t，nine去掉e，five和twelve 去掉ve加上f。 ③ 指twenty→twentieth等。
• 若加“ed/ing”，以下情况要注意： 词尾有e只加d，i ng去掉无声e； 词尾ie变成y，然后再加ing； 辅音之后y结尾，Y要变i加ed； 现在分词不变y，直接加上ing； 词尾重读闭音节，结尾辅音都双写， r做结尾也一样，重读音节r双写； 结尾字母若是“t”，不是重读也双写。 过去分词过去式，不按规则也有些。
