All living things need clean, fresh water to survive. Ninety-seven percent of the water on Earth is in the ocean. The salt in the ocean water makes it unusable for drinking. Another two percent is frozen in the ice caps and glaciers on the Earth. This leaves one percent of the water on Earth available for us to use. 【小题1】 Where you live, the amount of rain that falls, and how water is collected and reserved all affect the amount of cool, clear water available.

One factor that we can’t change is where it will rain. The amount of rain an area receives affects the amount of water available for use. Some major cities are located in areas where they can get water from the ground. Other areas use surface water from lakes, rivers, or streams. 【小题2】

According to a study done by the state of California, the average person uses over one hundred gallons of water per day. Water is used for drinking, taking a shower or bath, brushing teeth, washing hands, cleaning dishes, doing laundry, and flushing toilets. Using water wisely is important.

【小题3】 Today, we have many helpful tools to help us save water. There are low-flow shower heads and faucets(水龙头), dishwashers and washing machines that use up to 50% less water, and toilets that use only one-third of the water that they did a few years ago. Installing these items in your home is the first line of defense against wasting water.

There are many other ways you can help. Don’t leave the water running when you brush your teeth. Take a shower rather than a bath. 【小题4】 If you find one, let your parents know. A good way to have cool water available all the time is to keep a pitcher in the fridge. This way you won’ have to wait for the water in the pipes to bring you colder water to drink. Only run your clothes washer and dishwasher when they are full. This can save hundreds of gallons of water a year.

【小题5】 Learning to use it wisely will ensure that it will always be available. So, make a fuss and conserve water. It’s worth it!

Everyone struggles writing. 【小题1】 Writing is hard. All writers struggle at some point. And even if writing has come easily for you, at some point in your work as a student ,eventually you're going to hit a roadblock（路障）. 【小题2】 When the writing was going well, what was happening? When the writing wasn't going well, what was happening?

【小题3】 Most people's negative writing experiences happened because of some specific requirements like an exact length. They focus on and worry about what the final product has to look like, like how many pages for a research essay, or if it is in the second or third language, or grammar, like whether it gets communicated in the right language.

Another problem can arise when the need to do well on a paper is extremely important, like a timed essay exam, or a college application essay, or a research paper at the end of the term, and it's tied to the entire grade for the class. So worrying about what will happen if they don't do well- get bad grades, or don’t get into college - creates anxiety.     【小题4】

Try to move to more positive projects. Usually when writing comes easily, the writers feel they have something important to say. 【小题5】 What personal understanding of the subject can you bring to your paper? Why is this subject important? For whom is it meaningful? Who will be reading it? What is it that you really want to say to readers? Those thoughts can cause writing's change for all writers.

Why is a compliment so impactful? One of the most important things to humans is to feel valued and respected by others, says Vanessa Bohns, a social psychologist, who has researched compliments. According to her research, people feel “significantly better” after both giving and receiving a compliment. 【小题1】

“You handled that situation so well.”

Bohns recently used her favorite compliment when she saw a server address a difficult situation with a customer at the bar. “I like it so much because you use it in anxious moments where the other person is often unsure of whether they handled a situation OK,” she says. In situations that call for a compliment, don’t second-guess yourself. Give your compliments generously. 【小题2】 That concern is unfounded.

“【小题3】”

This compliment — one of Bohns’ favorites — works well among romantic partners and close family members. “It’s a beautiful way to highlight how their presence turns life into something meaningful, despite boring routines of our everyday lives,” she says. If you’re afraid that giving a compliment like this will feel strange, you’re not alone. 【小题4】 If it makes you personally feel like the bar is lowered for you to give a compliment if you write it down, or if you practice saying it out loud or giving your pet cat the compliment first, do that.

“Hey, great dress!”

Feel free to compliment strangers. In Bohns’ research, students on a college campus were told to approach a stranger of the same gender and compliment them-about, for example, their nice shirt. Before heading out, the study participants tended to underestimate their positive effect while overestimating how annoying it would be. Across all contexts, strangers are more likely to be pleased than confused. Plus, who knows? 【小题5】
