It is common and usual to see people freak out when they face challenges in their life. We all pass in different life problems and challenges. No one is free of life problems. Only a dead man faces no problem. As long as you are alive, challenges are everywhere.

    How do you face problems and challenges in your life? Problems and challenges are the building blocks of your personality. They make you who you are. Besides, whether what happened in your life builds or destructs you depends on how you look at it. If you take your problems as troubles, they will be troubles and may cause destruction. If you take them as constructive tools, you are going to be built up on them.

    Problems are everywhere. No one can avoid them. And they are good too. They open up a different look and opportunity if you are willing to see. When you face troubles, do not frustrate or freak out. Just cool yourself to think in a different direction. Think in a positive way. Every problem has its own good as well as bad sides. Focus on the good one. Look at the bright side.  Besides, there is always a good person, perhaps your mom or dad, or one of your friends, right beside you who can turn everything into your best if you are willing to turn to them. No matter what happens, they will be there to help you. Trust them and they will never let you down. All you need to know is that you are loved wherever you are.

    Today just as technology changed the face of industry, farms have undergone an "agricultural revolution". On the farm of today, machines provide almost all the power.

    One of the most important benefits will be the farm computer. The computers help them keep more accurate records so they can make better decisions on what crops to plant, how much livestock (家畜) to buy, when to sell their products, and how much profit they can expect. Many computer companies have been developing special computer programs just for farmers. In the future, farmers will be able to purchase computer programs made to their needs. Because of the growing importance of computers on the farm, students at agricultural colleges are required to take computer classes in addition to their normal agricultural courses. There can be no doubt that farmers will rely on computers even more in the future. While the old-time farm depended on horse power, and modern farms depend on machine power, farms of the future will depend on computer power.

    Another technological advance which is still in the experimental stage is the robot, a real "mechanized hired hand" that will be able to move and, in some ways, think like a human being. Agricultural engineers believe that computer-aided robots will make big changes in farming before the end of the century. Unlike farmers of the present, farmers of the future will find that many day-to-day tasks will be done for them. Scientists are now developing robots that will be able to drive tractors, and harvest fruit. Even complex jobs will be done by robots. For example, in order to milk their cows, farmers must first drive them into the barn, then connect them to the milking machines, watch the machines, and disconnect them when they are finished. In the future, this will all be done by robots. The complete mobilization (活动) of the farm is far in the future, but engineers expect that some robots will be used before long.

The Best and Worst Things to Buy in March

Frozen food

    Grocery store ads aren't the only places to find deals on freezer-section treats. To take advantage of the deepest discounts, combine coupons (优惠券) from sponsoring brands, such as Dole, Green Giant and Tyson Foods, with grocery store sales. Plus, look for printable savings on Coupons.com and EasyHomeMeals.com. Brands participating in National Frozen Food Month will offer more than 180,000 coupons that make frozen food among the best things to buy in March.

Boxed chocolates

    If you desire to give a gift to a friend in March, consider chocolate. Two minor holidays in March provide the perfect excuse: National Chocolate Caramel Day on March 19 and National Chocolate-Covered Raisin Day on March 24. You can discover chocolate deals online as well as in stores. Head to sites like RetailMeNot.com to find discount coupons for boxed chocolate savings of 10 percent or more.

New cars

    With the latest car models filling dealers' lots, you'll have a hard time finding discounted models from the year before. Car dealerships are less motivated to offer steep discounts from March through May. Instead, plan to buy your car during the fall or winter. You should also research the auto you want at TrueCar before heading for the dealership. The site offers information on what people in your area paid for vehicles equipped with the options you want.

Spring clothing

    When warm weather makes you want to head outdoors, resist the urge to do so wearing the latest fashions. You won't find March deals on swimsuits, Easter dresses or other spring items. To find discounts on clothes of this spring, hold off until Memorial Day weekend. You can also look for online and in- store savings at Amazon, Macy's, Saks Fifth Avenue and other retailers.

    There's no doubt that water is vital to any life. About 60 percent of the average adult human body is made of water. This includes most of your brain, heart, lungs, muscles and skin, and even about 30 percent of your bones. Yet there's little scientific agreement about the exact amount of the stuff an individual should consume each day. So how much water do you actually need to drink to be healthy?

    You may have heard that you should drink eight 8-ounce glasses of water a day. Yet, the downside of this rule, researchers say, is that drinking water by the glass is not the only way that humans take in it. The “8 X 8” rule essentially overlooks two big sources of daily water consumption. One such source is food. Everything you eat contains some water. Watermelons, for example, are more than 90 percent water by weight. Different diets naturally contain different amounts of waters, and the counts. The other key water sources are other beverages. Non-alcoholic drinks such as coffee, and tea, contain mostly water and all contribute to your hydration（水量）.

    So, between all the food, water and other fluids you consume in a day, how much water should you aim to take in?

    The National Academics of Sciences suggests that woman consume a total of approximately 2.7 liters (91 ounces) of warm from all beverages and foods each day and men 3.7 liters (125 ounces). But these are just general guidelines.

    The truth is, there is no magic standard for hydration—everyone's need vary depending on their age, weight, level of physical activity, general health and even the climate they live in. The more water you lose, the more water you'll need to replace with food and drink. If you are looking for concrete advice, though, the best place to look is within. Drink up when you're thirsty.

In many ways, Providence Mount St. Vincent in Seattle is a typical senior living community. It is home to about 400 elderly people and provides them with different types of assistance. However, it is also the Inter-generational Learning Center—a preschool where children and seniors have the chance to bond（结成友好的关系）.

    Established in 1991, the ILC's purpose is to allow kids to learn about acceptance while also being nurtured. It also aims to help seniors develop a greater sense of self-worth and strengthen social interactions. Babies to prekindergarten-aged children are placed into six different classes at the ILC. The kids attend art and music classes, as well as story time and exercise time with the seniors. Marie Hoover, ILC director, said that interacting with the seniors has proven beneficial for the young ones, making them more open-minded.

    “For the ILC children, interacting with the residents is simply part of their day-to-day life here and the way aging is 'normalized', which may be the most important benefit they receive,” Hoover said.“ I've had parents call me years after their children have graduated from our program to let me know about some incidents when their child was the first to warmly greet someone who happened to be in a wheelchair.”

    As for the seniors, they're delighted by the companionship the children provide. The children bring so much energy and joy to our residents. Many of residents are widows or widowers and can become lonely. Their adult children may still be working, so they may not get to see them as often as they would like. Having the children stay with the old makes our residents feel they are still part of a community. The young and the old connect and learn from one another at this unique facility.

    Travelling can be a fun way to gain life experiences, especially during a week-long school vacation. But what if you're a student and don't have enough money for a trip? Don't worry.

Here are some useful tips.

    Save: This probably is the most important preparation for travelling. Cut expenses to fatten your wallet so you'll have more choices about where to go and how to get there.

    Plan ahead: Don't wait until the last minute to plan your trip. Tickets may cost more when bought on short notice. Giving yourself several months to get ready can mean security(安全)and savings.

    Do your homework: No matter where you go, research the places you will visit. Decide what to see. Travel books will provide information on the cheapest hotels and restaurants.

    Plan sensibly(明智地): Write down how much you expect to spend for food and hotels. Stick to your plan or you may not have enough money to cover everything.

    Travel in groups: Find someone who is interested in visiting the same places. By travelling with others you can share costs and experiences.

    Work as you go: Need more money to support your trip? Look for work in the places you visit.

    Go off the beaten path: Tourist cities may be expensive. You may want to rethink your trip and go to a lesser-known area. Smaller towns can have many interesting activities and sights.

    Pack necessary things: The most important things to take are not always clothes. Remember medicine in case you get sick and snacks in case you can't find a cheap restaurant.

    Use the Internet: The Net can help to save money. Some useful websites include www. Iravelocity.com, www.bargains-lowest fare.com and www.Economy travel.com.

    By planning sensibly, even students can enjoy the travel. Your travel experiences will be remembered for a lifetime.
