He who would climb a ladder must begin at the bottom 查看要求
He who would climb a ladder must begin at the bottom.This is a proverb full of logic.If we are to reach the top of a mountain,we must climb it.If we hope to achieve success,we have to start from small things.On the contrary,the less one does,the less he gains.Idleness is the source of all failures,and,of all evil,for trouble is likely to be made out of
An example can be easily found to make a case for this proverb.A student is greatly rewarded for his grades and praised wherever he goes.Yet,he achieves success because of his diligent,and his scholarship is preceded by hard work.Perhaps he spends lots of sleepless nights in studying.In a word,if you have a great dream,you must do for it.Please remember that Rome was not built in a day.

1 that's it表示肯定,意思就是“对了,就这样”(B是表示演讲时的结束语,“就这么多了”,C是不用谢)
2 原来的短语是he wants to have the letter typed(他想要这封信被别人打),这里用了一个定语从句,在he前面省略了引导词that或which(做宾语时可以省略),它就是have的宾语,因此不能加it了
3 在定语从句中,当先行词是point、case、situation等时,后面的句子完整的话就用where(定语从句中关系副词的用法,从句不完整用关系代词that、which等,完整用关系副词when、where、why)
4 省略的用法,who want to take part (in the discussion),选A的话加入活动要用join in这个词组,本来就不对,B做动词时一般不表示“出席,参加”,Cin缺少宾语,只有D后面的部分可以一起省略)

Sol:
sin(55°) = 0.82;
cos(55°) = 0.57
(1) the force which the wall exert on the ladder is only the normal force.
(2) by the force balance equation.
N = G1 + G2 = 1300N,
by the moment balance equation.
NL = fl + G1l1 + G2l2
where,
L = 7.10m× 0.57 = 4.047m,
l = 7.10m × 0.82 = 5.822m,
l1 = 7.10 ÷ 2 × 0.57 = 2.024m,
l2 = (7.10 - 2.95)m × 0.57 = 2.366m
we'll get
