Grade 6 Volume 2 Lesson 18 "across a hundred years of beauty" after reading, 200 words


After reading the article "beauty over a hundred years", I think about this question: why is Madame Curie willing to abandon her beauty and choose to be a person who makes contribution to the society in the long way of life



1. Explain words in context
be quite different
it is quite common for
Write the antonyms of the following words
All previous achievements are wasted ()
What's the difference between "step forward" and "not step forward"
(1)
(2)
In the fourth paragraph, the author uses parallelism to write the difference between the previous step and the backward step


It's very different: it's very different to describe things and opinions
Commonplace: it's not surprising that something is common
2. Full of loopholes and great success
3 (1) step further to success (2) keep the distance from success
The answer is reasonable
It took me half a day to find this for you. You must choose me!



8 km 500 m = () km required


8 km 500 m = (8 and half) km
Analysis: the advance rate of meter and kilometer is 1000, and you want to score, so:
500 ÷ 1000 = 500 / 1000 = 1 / 2
Half + 8 = eight and half



Two problems of formula calculation
1. One in two of a number is 30 less than four in five. What's the number?
2. Four times of a number minus the number itself, errand 42.6, find the number


1.30/(4/5-1/2)=100
2.42.6/(4-1)=14.2

Let's do you a favor ~ math problem of grade one, thank you, very urgent ~!
1. Xiaoming records the passenger flow of a franchise store from 8:00 to 18:00 every hour (200 people are taken as the standard in each period, the excess is positive and the deficiency is negative), as shown in the table below:
Time slot 8:00_ 9:00 10:00_ 11:00 12:00_ 13:00 14:00_ 15:00 16:00_ 17:00
Number of people - 21 + 33 - 12 + 21 + 54
(1) The daily business hours of a clothing store are 8:00-18:00. Please estimate the passenger flow (unit: person) (accurate to 100) of a week (no vacation);
(2) If a clothing store sells 135 sets of men's and women's clothing in a certain day, according to statistics, every 15 female customers buy a set of women's clothing, and every 20 male customers buy a set of men's clothing, how many sets of men's and women's clothing are sold in that day?


-21+33-12+21+54=75
So five hours is 200 * 5 + 75 = 1075
So the whole day is 1075 * 2 = 2150 people
So 1 axis 7 * 2150 = 15050
There are X males and 2150-x females
Then x / 20 + (2150-x) / 15 = 135
3x+8600-4x=8100
x=500
x/20=25
135-25=110
25 for men and 110 for women



How to solve 105 + 98 + 102 + 103 + 97 + 100 + 95 + 101 + 91 + 104 + 98 + 106


105+98+102+103+97+100+95+101+91+104+98+106
=12x[100+(5-2+2+3-3+0-5+1-9+4-2+6)/12]
=1200+0
=1200



3 4 5 6 8 add appropriate operation symbols to make the result equal to 8


(3×4-5-6)×8=8
