第七十七章 又是不知道起什么名字的一章(1 / 2)

Δ,希腊字母,中文名称为德尔塔,小写为δ,常用作数学之中的判别二次函数有无实根,即Δ=b-4ac,为正则有两个实根,为零则有一个实根,若为负则无实根。</p>

在数学之中,Δ为正或者为负的函数一样多,但在名为人生的考试题之中,为正的情况很少,更多的是为零,或者为负,即只有一个跟,或者……压根无根。</p>

中午讲完之后,下午下课之时,樱井惠和刘承泽两个人依旧在一起讲题。</p>

至于风言风语刘承泽也无所谓了,女孩子都不在乎,他一个男生还能缩手缩脚?</p>

“今天真是谢谢你了,刘君。”</p>

放学时,樱井惠对刘承泽感谢道:</p>

“还麻烦你花了这么长时间教我。”</p>

刘承泽摆摆手。</p>

“没什么,不麻烦的,怎么样?今天讲的你听懂了吗?”</p>

“嗯。”</p>

樱井惠点点头,由衷地赞叹道:“刘君讲的真的很好,不愧是能做补习教师的人,真的很厉害。”</p>

“你夸的太过了啊。”</p>

刘承泽笑着谦虚了一下,随后说道:“那么明天见了,樱井。”</p>

“明天见,刘君。”</p>

两人微微鞠躬,随后刘承泽率先走出了教室。</p>

和往日一样,刘承泽出了校门,在校门口那条隐蔽的小巷子里等带着结城美良。</p>

虽然结城美良早上的时候跟刘承泽说放学的时候,两个人分开走,但刘承泽怀疑今天结城美良似乎来了什么不太方便的事,所以还是决定在这里等一等她。</p>

小巷子口能够完整且清楚地看见学校门口,刘承泽看着从校门如同河水一般倾泻而出的学生们,默默寻找着结城美良的身影。</p>

没过多久,结城美良小小的身影便出现在了人群之中。</p>

她的心情似乎不太好,脸色看上去有一些差,低着头,脑后的马尾一甩一甩地慢慢向刘承泽走来,走了几步后突然想起了什么,又准备调头向通往心斋桥的方向走去。</p>

可随后她又转了回来。</p>

结城美良看着巷子口的刘承泽,撅了下嘴,最终走进了巷子之中。</p>

“不是告诉你今天不用等我了吗?”</p>

结城美良看着刘承泽,略带着不满地说道。</p>

“嘛,毕竟住在一块,我觉得还是一起走比较好。”</p>

!</p>

刘承泽的话让结城美良一下子瞪大了双眼,少女脸色微红,快步上前就要踢刘成泽一脚。</p>

“什什什么叫住在一起!说话给我注意一点!”</p>

“是是,我知道了。”</p>

刘承泽微微闪身,避开了结城美良踢过来的脚。</p>

我就那么像性·骚扰的人吗?</p>

刘承泽心中很是无奈,只得赶紧转开话题,免得再给结城美良火上浇油,于是便对少女说道:“赶紧走吧,一会还得打工呢。”</p>

说完转身向巷子的另一头走去。</p>

结城美良看着刘承泽的背影,犹豫了一下,随后一跺脚。</p>

“真是的。”</p>

少女不满的嘟囔了一句后,选择了跟在刘承泽的身后。</p>

结城美良出来的时候已经有些晚了,两个人从巷子里出来时,街上已经没有几个穿着兰馨学院校服的学生了。</p>

和昨天一样,穿过淀屋桥,再往前不远就是心斋桥商业区了。</p>

刘承泽回头看了看低着头,跟在自己身后的结城美良,忽然想起了一件事:</p>

女生好像在来事的时候,都要休息的吧?</p>
