This first example shows how auto sales at Uniton Motors have changed since 1960. in 1960, sales were about 500,000 units. From 1960, sales declined to a low of around 300, 000 in 1965. from 1965, sales incread steadily until they reached a high of around 900,000 in 1974. then, becau of increasing imports, sales began a long decline, to a low of around 500,000 units. Since 1980, sales have stopped their decline, and have remained fairly steady.
Now let’s look at sales at Federal Motors. In 1960, sales were about 900, 000 units. They ro to a million in 1965, and then they began a long decline. In the fifteen year period from 1965 to 1980, sales dropped about 30%, to around 700, 000 units. From 80 to 85, sales re
mained fairly flat, and then they began to ri. since 85, sales have been improving, and the company is regaining market share. In 1965, sales in Ferderal Motors were more than triple the sales at Union. In 1973, sales at Union Motors surpasd Ferderal Motors for the first time. Sales at Federal were higher than Union except for the five year period from 73 through 78. 苹果平板怎么截图

This graph shows changes in the unemployment rate in the US.
This graph shows the decrea in average family size in the US. US families in 1989 averaged only 3.16 people, the smallest size since 1940. this drop is primarily the result of lower birthrates and continued increas in the number of single-parent families. Married-couple families now make up only 56% of all American houholds.

This line graph shows how the voter approval rating for a city government has changed during the past twelve months. Note that the approval rating was at its highest during the first three months and its lowest in month eight. This graph shows the rate of population growth in veral countries.
It also shows the literacy rate in each of the countries. The adult literacy rate is the percentage of adults who can read and write. The axis on the left gives the percentage growth rate, and the axis on the right gives the literacy rate. For example, the percentage annual growth rate of Brazil is about 1.4%. its literacy rate is 0.83 or 83%. For the counries, the graph suggests that countries with a higher literacy rate and have a lower rate of population growth.
This graph shows how the world’s consumption of energy is increasing. The scale on the left is in units of quadrillion Btu’s or British Thermal Units. In 1983, the world’s energy consumption was two hundred eighty three quadrillion Btu’s.
This graph shows how pasnger car exports changed in the five year period ending in 2003. it shows the value of exports in billions of dollars for ven exporting countries.
怎样瘦脸和双下巴This graph gives the caus of traffic fatalities bad on four thousand parate accidents. Each bar show the number of fatalities for each cau. The axis on the right gives the percentage. For example, about twelve hundred deaths were due to speed. The line graph above the bar graph shows the cumulative percentage of tatalities due to each cua. It shows that 72.3 percent of the traffic fatalities were due to two caus, lane changes and unsafe speed.

This first example compares math scores for five countries: Japan, France, the UK, the US, and Sweden. Each bar indicates the mean percent of items answered correctly on a
mathematics test of 8th grade students. For example, the country with the lowest score was Sweden, which is “E”.
Listen to the information about each country. Then indicate which bar reprents that country. American students scored about 45%, which was the cond lowest. French students didn’t do as well as the Japane, but they scored over 50%, which was cond best. Now let’s compare the amount of money which is spent on education in each of the countries. This graph shows that there must be other factors besides spending which affect test scores. In the US, for example, there is a higher ratio of spending for higher education than for basic education.
Today there are about 5.2 billion people on the planet Earth. Current trends indicate that the Earth’s population will increa by more than 50%, to 8.2 billion by the year 2020. about 93% of the world’s population growth is in the developing nation. This pattern is likely to continue, and the population will increa rapidly even though growth rates are expected to decline. World population today is increasing at about 1.8% annually. The rat
e is expected to drop to about 1.4% annually by the year 2020. this graph gives the number of births per woman 15 to 49 years old. Asia and Latin America both have the birthrate around 3.5. Two births per woman is considered replacement level for zero population growth. The birthrate is Sub-Saharan Africa is about 6.5, which is the highest. Japan’s birthrate is the lowest, at around 1.7. the birthrate in the US is slightly lower than Europe, but it isn’t as low as Japan. The birthrate in Europe is just below 2.0, its rate is higher than Japan and the US, but much lower than in the developing countries. This graph compares how income is distributed among the richest and poorest gments of each country. The income ratio here means the top 20% of houholds divided by the bottom 20%. In Brazil, for example, the top 20% of houholds receive 66.6% of the nation’s income, compared to the bottom 20%, which receive just 2.0%. this works out to an income ratio of 33. this graph suggests that one factor in economic growth might be how income is distributed throughout a country. The countries with lower income ratios have been growing faster. 大学三年规划
