Animals, including insects, do not have a language like ours. They do not talk to each other in words and sentences. But if we watch them, we can see that they do have ways of communicating with each other.

    Can you see the rabbits' tail? When rabbits see this white tail moving up and down, they run too. The rabbit has reminded them of potential dangers without making a sound. It has given them a signal.

    Many other animals use this kind of language. When a cobra (眼镜蛇) is angry, it raises its hood (兜帽) and makes itself look fierce. This warns other animals. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.

    Some animals say things by making sound. A dog barks, for example, when a stranger comes near. A cat purrs (猫的呜呜声) when pleased. Some birds make several different sounds, each with its own meaning. Sometimes we human beings speak in the same way. We make sounds like “Oh” or “Ah!” when we are frightened or pleased or when we drop something on our toes.

    But we have something that no animals have — a large number of words which have the meanings of things, actions, feeling or ideas. We are able to give each other all kinds of different information in words and sentences, which no other animals can do. No other animals have so wonderful a language as we have.

    In the past, people who graduated from college felt proud of their academic achievement and confident that their degree would help them find a good job.

     However, in the past four years the job market has changed dramatically. This year's college graduates are facing one of the worst job markets in years. For example, Ryan Stewart, a graduate of San Jose University, got a degree in religious studies, but no job prospects. He points out that many people already working are getting laid off and don't have jobs, so it's even harder for new college graduates to find jobs.

    Four years ago, the future looked bright for the class of 2013. There were many high-tech job opportunities. Graduates received many job offers, and they were able to get jobs with high salaries and benefits such as insurance and paid vacations. However, “Times have changed and it's a new market,” according to Cheryl Allmen- Vinnidge of the San Jose State Career Center.

    Allmen-Vinniage says students who do find jobs started preparing two years ago. They worked during summer vacations, they have had several internships（实习）, and they have majored in one of the few fields that are still hot, like chemical engineering, accounting, or nursing, where average starting salaries have actually increased over last year. Other popular fields (like information system management, computer science, and political science) have seen big reduction in starting salaries.

    Ryan Stewart (he had hoped to become a teacher) may just end up going back to school. “I'd like to teach college some day and that requires more schooling, which would be great in bad economy.” he said.

    In conclusion, these days, to some students a degree may not be a ticket to instant wealth. For now, they can only hope its value will increase over time.

    Even by the standards of poor countries, India is alarmingly — and unnecessarily — dirty. It needs to clean up. Most time of year, its capital, Delhi，smells as if something is burning. That is because of many things: the carcinogenic diesel（柴油）that supplies three quarters of the city's motor fuel, the dirty coal that supplies most of its power, the rice stalks that nearby farmers want to clear after the harvest and so on. All these make Delhi's air the most poisonous of any big city.

    This does not just make life unpleasant for a lot of Indians. It kills them. Recent estimates put the annual death toll from breathing PM 2.5 alone at 1.2—2.2 million a year. The lifespan of Delhi residents is shortened by more than ten years, says the University of Chicago-Consumption of dirty water directly causes 200,000 deaths a year, a government think-tank estimates, without measuring its contribution to slower killers such as kidney disease. Some 600 million Indians, nearly half the country, live in areas where clean water is in short supply. As pollutants taint groundwater, and global warming makes the vital monsoon（季风）rains more abnormal, the country is poisoning its own future.

    Indian pollution is a danger to the rest of the world, too. Widespread dumping of antibiotics（抗生素）in rivers has made the country a hotspot for anti-microbial（抗微生物）resistance. Emissions of carbon dioxide, the most common greenhouse gas, grew by 6% a year between 2000 and 2016, compared with 1.3% a year for the world as a whole.

    In the past India has explained its failure to clean up its act by pleading poverty, noting that richer countries were once just as dirty and that its output of waste per person still lags far behind theirs. But India is notably grubby（肮脏的）not just in absolute terms, but also relative to its level of development And it is becoming grubbier.

    It is true that some ways of cutting pollution are expensive. But there are also cheap solutions，such as undoing mistakes that Indian bureaucrats（官僚）have themselves made. By funding rice farmers, for instance, the government has in effect cheered on the overusing of groundwater and the burning of stalks. Rules that encourage the use of coal have not made India more self-reliant, as intended, but instead have led to big imports of foreign coal while blackening India's skies. Much cleaner gas-fired power plants, meanwhile, sit idle.

    Reliant on big business for funding and on the poor for votes, politicians have long ignored middle-class complaints about pollution, failing to give officials the backing to enforce rules. That is a pity, because when India does apply itself to ambitious goals, it often achieves them

    Next year it will send its second rocket to the Moon.

    Narendra Modi, the prime minister, promised with admirable frankness when he took over to rid the country of open defecation（缺陷）. Four and a half years and some $9 billion later, his Clean India campaign claims to have sponsored the building of an astonishing 90 million toilets. This is impressive, but India is still not clean. Its skies, its streets, its rivers and coasts will remain dangerously dirty until they receive similar attention.

Volunteering

    Just like the animals we shelter, people are very special to us. The Animal Shelter of Sacramento County has 300 active volunteers and is always eager to add more. If you have a few hours each week and a love for dogs and cats, we at the shelter welcome your participation.

    Youth Volunteers

    Children 10 years of age or older are allowed to take part in some of our programs as youth volunteers when accompanied by an adult. The adult can be a parent, or guardian 18 years of age or older. Volunteering is rewarding for a number of reasons. Youth volunteers learn responsibility as they serve the community. Volunteers are rewarded with the love for our sheltered animals. Volunteers learn about the needs of dogs and cats and how to care for those needs.

    Youth Volunteer Qualifications

    A youth volunteer must:

    *care deeply about animals and their happiness

    *complete an application form

    *be at least 10 years of age and accompanied by an adult

It's normal to long for the taste of potato chips or a cheese-covered pizza. Even though they're full of calories, eating them occasionally won't do much harm. However, according to the new numbers, young people are becoming more gluttonous. The BBC's Good Food Nation Survey showed that on average, 16 to 20-year-olds ate fast food at least twice a day in the UK. So what's behind this fast food binge (狂热)?

WebMD, an online publisher of news and information of human health and well-being, surveyed nearly 600 teenagers and adults in the United States. They found that the most common reason was our busy lifestyle. More than 92.3 percent of respondents said they were too busy to cook. Many find it challenging to balance work and life, and the convenience of fast food meets their needs. Fast food is readily available in corner stores and vending machines (自动售货机). Remember those instant noodle cups from the supermarket? They're ready in minutes, and you can store them at home for a long time.

But many people think this trend does no good. Sarah Toule, head of health information at World Cancer Research Fund, told the BBC: "It's frightening that people, especially younger generations, are eating so much fast food loaded with fat, sugar and salt, but offers little nutritional value."

She added, "Especially high in calories, fast food leads to unhealthy weight gain — which in turn increases the risk of 11 cancers later in life."

So what is the right thing to do? Toule suggested that young people should prepare meals in advance and learn to include the different food groups in their diets.
