Forget Twitter and Facebook, Google and the Kindle. Television is still the nost influential medium around. Indeed ,fot many of the poorest regions(地区)of the world, it remains the next big thing——finally becomes globally available. And that is a good thing, because the TV revolution is changing lives for the better.
Across the developing world, around 45% of families had a TV in 1995; by 2005 the number had climbed above 60% . That is some way behind the U.S. ,where are more TVs than people, and where people now easily get access to the Internet. Five million more families in sub-Saharan Africa will ger a TV over the next five years. In 2005 , after the fall of the Taliban(塔利班),which had outlawed TV, I in 5Afghans had one. The global total is another 150 million by 2013——pushing the numbers to well beyond two thirds of families.
Television’s most powerful effect will be on the lives of women. In India, researchers Robert Jensen and Emily Oster foumd that when TVs reached village s, women were more likely to go to the market without their husbands approval and less likely to want a boy rather than a girl. They were more likely to make decisions over child health careTV is also a powerful medium for adult education. In the Indian state of Gujarat,Chitrageet is a popular show that plays Bollywood songs with words in Gujarati on the screen. Within six months, viewers had made a small but significant(有意义的) improvement in their reading skills.

Businesses are witnessing a difficult time, which has in turn produced influence on consumers’ edsire to go green . However, shoppers are still laying stress on environmental concerns.
Two thirds of customers say that environmental considerations inform their purchases to the same degree as they did a year ago, while more than a quarter say that they are now even better aware of the environmental effect on what they buy.
This may help to influence how shops store goods on their shelves. And the companies should still make efforts to become more envitonmentally friendly. Two out of three people think it is important to buy from environmentally responsible companies,with about one in seven saying that they had even decided to take their custom elsewhere if they felt a company’s environmental reputation was not good enough.
Harry Morrison, chief executive(主管)of the Carbon Trust, sympathizes：“I understand this situation where survival is very important now. But from environmental considerations, the clocd is ticking—we don’t have much time. In addition, cutting carbon has an immediate effect as costs drop and a mediun-term benefit for the brand.”
Larger companies have an extra motivation to look at reducing their carbon footprint, as new rules next year will require businesses bo buy carbon allowances to make up for their emissions(排放). Those that have taken early action will hav e a head start. More than two thirds of consumers are not clear about which companies are environmentally responsible. This suggests that firms that are able to relay clearly their message to the public will be in a pole position to attract shoppers.
The Carbon Trust believ es that it can help by informing customers about the good work companies are doing.“When companies are granted(授予)the standard, they can use a logo(标识)in all their marketing which makes it clear that they are working towards cutting emissions,”Mr.Morrison said.
64.What’s the main idea of the passage?
A.Businesses are finding ways to send their message to the shoppers.
B.Companies will soon get information about cutting carbon emissions.
C.Firms are making efforts to encourage customers to keep goods at home.
D.Firms are urged to cut carbon emissions by shoppers’environmental awareness.
65.The underlined word“inform”in Paragraph 2 probably means“ ”.
A.affect B.change C.disturb D.reject
66.According to Harry Morrison, businesses .
A.will benefit from cutting carbon emissions
B.should buy carbon allowances for shoppers
C.are required to make up for their carbon emissions
D.have encouraged shoppers to take their custom elsewhere
67 .We can learn from the passage that businesses will .

In the United Statcs, there were some well-constructed houses for native Indians, ranging from the simple brush shelter to the five-storied pueblo.
In the eastem United States, one of the existing types was that commonly know under the Algonkian name of wigwam in which the Iroquois Indians lived. The wigwams were of wagon-top shape with straight sides and ends, made by bending young trees to form the round shape. Over this shape pieces of tree bark were laid to protect the Indians from bad weather. Over the bark dried grass was added. A small hole allowde smoke to escape from the top. Doorways at each en served also as windows, The Iroquois Indians built trunk walls all around their villages. The wall had only one opening, They could quickly close this cpening if their enemies came near.
Interestingly, the Choctaw Indians in Mississippi also lived in a wigwam of a most primitive(原始的) construction, but different from those of the Iroquois Indians.The Choctaw Indians’wigwams, made from mud,cane and straw, were in the form of a bee-hive. The covering was made of a long, tough grass. A post in the centre supported the roof.A hole in the top admitted the light, and allowed the smoke to pass out.
The tipi tent-housing of the upper lake and plains area was put up with poles set lightly in the ground, tied together near the top, and covered with bark and grass in the lake country. It was easily portable, and two women could set it up or take it down within an hour.
The Pawnee, Mandan and other Indian tribes (部落) along the Missouri built solid ring-shaped structhures of trunk, covered with earth and dried grass,housing adozen families.

高考数学试卷2021：挑战高难度的数学题目
高考数学试卷一直以来都是考生们最为头疼的一项考试，因为其中的数学题目难度极高，需要考生们在极短的时间内迅速作答，而且还要保证答案的准确性。2021年的高考数学试卷更是如此，其中的一些题目难度甚至超出了往年的水平，令许多考生感到十分困难。下面，我们就来看看2021年高考数学试卷中的一些难题，以及它们的解答方法。
难题一：函数极值问题
这道题目要求我们求出函数f(x)=x^3-3x^2+2x+1在区间[-1,3]上的最大值和最小值。
首先，我们需要求出函数的导数f'(x)，然后将其置为零，求出所有的驻点。这里，我们可以得到f'(x)=3x^2-6x+2，将其置为零，得到x=1±√3/3。接下来，我们需要将驻点和区间端点带入函数中求出函数值，然后比较大小，得到最大值和最小值。
经过计算，我们可以得到函数在x=-1处取得最小值-1，而在x=1+√3/3处取得最大值7-4√3/3。
难题二：亮兆三角函数反函数问题
这道题目要求纤神我们求出函数f(x)=sin(x)+cos(x)在[-π/4,π/4]上的反函数。
首先，我们需要将函数f(x)转化为一个单调递增的函数，这里敬竖租我们可以将其表示为f(x)=√2sin(x+π/4)，然后求出其反函数f^-1(x)。
