解释：
现在是向上，假设斜率为1，预测forward向下，假设为-1，这样并不能说明forward就是在current下面吧，至少是没有完全在forward下面？
NO.PZ201712110200000106 问题如下 Baseon Exhibit 1 anassuming Tyo’s market views on yielcurve changes are realize the forwarcurve of whicountry will lie below its spot curve? A.Country B.Country C.Country B is correct. The yielcurve for Country B is currently upwarsloping, but Tyo expects a reversin the slope of the current yielcurve. This means she expects the resulting yielcurve for Country B to slope wnwar whiimplies ththe resulting forwarcurve woullie below the spot yielcurve. The forwarcurve lies below the spot curve in scenarios in whithe spot curve is wnwarsloping;the forwarcurve lies above the spot curve in scenarios in whithe spot curve is upwarsloping.A is incorrebecause the yielcurve for Country A is currently upwarsloping anTyo expects ththe yielcurve will maintain its shape anlevel. Thexpectation implies ththe resulting forwarcurve woulabove the spot yielcurve.C is incorrebecause the yielcurve for Country C is currently wnwarsloping anTyo expects a reversin the slope of the current yielcurve. This means she expects the resulting yielcurve for Country C to slope upwar whiimplies ththe resulting forwarcurve woulabove the spot yielcurve. 我知道B是对的，但是C为什么不对？

COUNTRY C 这句话We assume thfuture spot rates will lower thtoy’s forwarrates for all maturities.\"是什么意思呢？
NO.PZ201712110200000106 B说，“We assume thfuture spot rates will higher thcurrent forwarrates for all maturities.\" C说，“We assume thfuture spot rates will higher thcurrent forwarrates for all maturities.\" 原文中是拿future spot rate和current forwarrate做比较；题目中是比较forwarcurve 和spot curve。 这里两组Rate到底哪个对应哪个？他们的含义区别是？有点晕了。 看到其他老师，这里只需要用到exhibit1和\"reversal\"去判断？我不太理解。 比如B，表格里面已经有个reversal了，从负数变成正数了。我之前理解这个reversal就是指的这个变化，但是看说后面还有reversal？ 请老师解答一下，谢谢！
老师，我对这个句话 B 国家 We assume thfuture spot rates will > current forwarrates for all maturities 有两种理解，不懂哪种是对的. 问题问哪个国家的forwarrate在上面 我这么想的 We assume thfuture spot rates will > current forwarrates for all maturities，这句话意思是说future spot curve 在上面么？（这是我的一种理解） （ 这个也符合题目说 B reverse， 变成了slope wnwar.） C说future spot rates will current forwarrates for all maturities， 这里面说的current forwar说站在0时刻用表格1 里面的 S1， S2, S3 etc推出来的forwarrate 比如下面图里面的 f ( 是么？) future spot rate就是说到了未来时间点那个真实的future spot rate (比如下面图里面的 S1’ ） ( 是么? ) （这是我的另一个理解）（如下图我画的） 下面一个题目问Tyo most likely perceives the bon of whicountry to fairly value 因为这个forwarrate是用现价（0时刻的spot rate们也是现价推出来的） 推出来的，所以如果forwarrate 小，说明现价高， 所以是被高估了。（是么？） 不懂我上面的理解都对么？
Country B Country C B is correct. The yielcurve for Country B is currently upwarsloping, but Tyo expects a reversin the slope of the current yielcurve. This means she expects the resulting yielcurve for Country B to slope wnwar whiimplies ththe resulting forwarcurve woullie below the spot yielcurve. The forwarcurve lies below the spot curve in scenarios in whithe spot curve is wnwarsloping;the forwarcurve lies above the spot curve in scenarios in whithe spot curve is upwarsloping. A is incorrebecause the yielcurve for Country A is currently upwarsloping anTyo expects ththe yielcurve will maintain its shape anlevel. Thexpectation implies ththe resulting forwarcurve woulabove the spot yielcurve. C is incorrebecause the yielcurve for Country C is currently wnwarsloping anTyo expects a reversin the slope of the current yielcurve. This means she expects the resulting yielcurve for Country C to slope upwar whiimplies ththe resulting forwarcurve woulabove the spot yielcurve.country C的spot rate 是wn sloping，为什么不能说明？
