September 9th comprises double "Nine", so it gets the name. In {#blank#}4{#/blank#}(real), it has been formed as early as the Warring States period. To the Tang Dynasty , it was{#blank#}5{#/blank#} (official) appointed{#blank#}6{#/blank#}the folk festival , and then it's followed so far. Nine also means Long in Chinese words. It's the Chinese Festival for the Elderly, {#blank#}7{#/blank#}reflects（反应）our behavior of respecting, caring , loving and helping the old.

    Yuan Longping was born in 1930.Since he graduated from Southwest Agricultural College in 1953, he{#blank#}1{#/blank#}(devote)his life to finding ways{#blank#}2{#/blank#}(grow)more and more rice. As a young man, he saw the great need for increasing the rice output. At that time{#blank#}3{#/blank#}(hungry)was a serious problem in many parts of the countryside. Yuan searched {#blank#}4{#/blank#} a way to increase rice harvests without {#blank#}5{#/blank#}(expand) the areas of the fields. In 1950, Chinese farmers could produce about 56 million tons of rice. In{#blank#}6{#/blank#}recent harvest, however, nearly 200 million tons of rice were produced. These increased harvests mean that 22% of the world's people{#blank#}7{#/blank#}(feed)from just 7% of the farmland in the world. Yuan Long Ping is now circulating his knowledge in India and many other less{#blank#}8{#/blank#}(develop)countries to increase their rice harvests.{#blank#}9{#/blank#}(thank)to his research, the UN is trying to rid the world{#blank#}10{#/blank#}hunger. Using his hybrid rice, farmers are producing harvests twice as large as before.

    A recent study found that people who live in colder climates consume {#blank#}1{#/blank#} (much) alcohol than people who live in warm weather.

    "Alcohol is something that everyone thought harmful for {#blank#}2{#/blank#} (decade), but no one has scientifically demonstrated it," a professor wrote in a press release.

Why do people in Russia drink so much? Everybody {#blank#}3{#/blank#} (assume) that's because the weather is cold. But we couldn't find a single paper {#blank#}4{#/blank#} (link) climate to alcohol intake. Since alcohol could increase warm blood flow in the skin, last month, the researchers in a study {#blank#}5{#/blank#} (suggest) that people should reach for booze (豪饮) when it's cold outside. The researchers combed through data to compare climate factors and alcohol consumption per capita (每人的). {#blank#}6{#/blank#} study also found that as temperatures and sunlight hours decrease, alcohol consumption goes up. Shorter hours of sunlight and cooler temperatures also relate {#blank#}7{#/blank#} higher rates of depression, {#blank#}8{#/blank#} is linked to an increase in drinking.

    The professor hopes this data will help influence health policies on alcohol abuse. "Knowing that cold places have more drink-related problems can could be {#blank#}9{#/blank#} (help) to the efforts in these areas {#blank#}10{#/blank#} (determine) better places," he said.

    If you live in Shanghai, you might have to take a lesson in sorting garbage {#blank#}1{#/blank#}is now required that people should sort garbage into four categories recyclable, {#blank#}2{#/blank#} (harm), dry and wet waste. However, if people fail to sort their garbage properly, they can {#blank#}3{#/blank#}(fine) up to 200 yuan.

    More cities are introducing similar regulations, {#blank#}4{#/blank#}(follow) the practice in Shanghai. However, garbage sorting is still a big problem in China. Only 30% of the {#blank#}5{#/blank#}(participant) think they are adequately sorting their trash. It's partly because many people lack their willingness to sort their own waste. "It's {#blank#}6{#/blank#} must to have a legal guarantee {#blank#}7{#/blank#}(promote) garbage sorting, said Liu Jianguo, a professor from Tsinghua University.

    Apart from China, many other foreign countries also {#blank#}8{#/blank#}(introduce)garbage-sorting regulations in the past years. In Japan, waste sorting has become a basic survival skill. There is a {#blank#}9{#/blank#}(fix) time for the disposal of each kind of garbage and littering can result {#blank#}10{#/blank#} high fines and even jail time. Over 90%o of the public believe that garbage sorting is important for the protection of the environment.

Emperor penguins (企鹅) are{#blank#}1{#/blank#}(large) penguins on Earth. Each adult is over a meter tall and weighs up to 40 kilos. Every year in May, mother penguins lay eggs on the coast.

During this time, {#blank#}3{#/blank#}eating any food, a father penguin can lose half of his body weight. By August, the mothers return just in time to see their babies come out of eggs.
