I was never very neat, while my roommate Kate was extremely organized. Each of her objects had its place, but mine always hid somewhere. She even labeled(贴标签) everything. I always looked for everything. Over time, Kate got neater and I got messier. She would push my dirty clothing over, and I would lay my books on her tidy desk. We both got tired of each other.

War broke out one evening. Kate came into the room. Soon, I heard her screaming. “Take your shoes away! Why under my bed!” Deafened, I saw my shoes flying at me. I jumped to my feet and started yelling. She yelled back louder.

The room was filled with anger. We could not have stayed together for a single minute but for a phone call. Kate answered it. From her end of the conversation, I could tell right away her grandma was seriously ill. When she hung up, she quickly crawled(爬)under her covers, sobbing. Obviously, that was not something she should not go through alone. All of a sudden, a warm feeling of sympathy rose up in my heart. Slowly, I collected the pencils, took back the books, made my bed, cleaned the socks and swept the floor, even on her side. I got so into my work that I even didn’t notice Kate had sat up. She was watching, her tears dried and her expression one of disbelief. Then, she reached out her hands to grasp mine. I looked up into her eyes. She smiled at me, “Thanks.”

Kate and I stayed roommates for the rest of the year. We didn’t always agree, but we learned the key to living together: giving in, cleaning up and holding on.

Ever wonder how much a cloud weighs? What about a hurricane? A meteorologist(气象学家) has done some estimates and the results might surprise you.

Let’s start with a very simple white puffy cloud—a cumulus cloud(积云). How much does the water in a cumulus cloud weigh? Peggy LeMone, senior scientist at the National Center for Atmospheric Research in Boulder, Colorado, did the numbers. “The water in the little cloud weighs about 550 tons,” she calculates. “Or if you want to convert it to something that might be a little more meaningful...think of elephants.” Assume(假设) an elephant weighs about six tons, she says, that would mean the water inside a typical cumulus cloud would weigh about one hundred elephants.

The thought of a hundred elephants’ worth of water floating in the sky begs another question—what keeps it up there?

“First of all, the water isn’t in elephant-sized particles(微粒); it’s in tiny tiny tiny particles,” explains LeMone. And those particles float on the warmer air that’s rising below. But still, the concept of so much water floating in the sky was surprising even to a meteorologist like LeMone. “I had no idea how much a cloud would weigh, actually, when I started the calculations(计算),” she says.

So how many elephant units of water are inside a big storm cloud—10 times bigger all the way around than the “puffy” cumulus cloud? Again, LeMone did the numbers: About 200,000 elephants.

Now, come to the calculations for a hurricane about the size of Missouri and the figures get really massive. “What we’re doing is weighing the water in one cubic meter theoretically pulled from a cloud and then multiplying by the number of meters in a whole hurricane,” she explains.

The result? Forty million elephants. That means the water in one hurricane weighs more than all the elephants on the planet. Perhaps even more than all the elephants that have ever lived on the planet.

A. A storm cloud weights about 200,000 elephants.

B. The water in the cloud is in very tiny particles.

C. There are less than forty million elephants living on the earth.

D. The water in a hurricane weights more than that in any other kind of cloud.

4.What is the best title for the passage?

A. Surprising Results

B. Elephants in the Sky

C. How Much a Cloud Weighs

D. How Much a Hurricane Weighs

Summer is the season to dive into new activities, and kick back and relax. And right now is the time to make sure that you’re ready for the great outdoors, the holiday planning and travel, and the bathing-suit beach days.

If you want to lose weight before summer, concentrate on dropping no more than a pound or two a week. 1. And when you trouble yourself, sooner or later you’re going to gain it back. Operate on a 500-calorie -a -day deficit (亏缺). 2. So if you cut 500 calories a day for seven days straight, you’ll lose a pound a week right there.

Operating at an inadequate (减少量)of 500 calories a day should involve both eating less and moving more: For example, you could consume 300 fewer calories and burn 200 extra per day.

Include both healthy eating and exercise in your weight-loss plan, and break the 500-calorie goal into smaller groups to make it more reachable. 3.

To Cut 100 Calories; 4. Have vegetable pizza instead of pepperoni (意大利辣香肠). Use our Nutritional Needs Calculator to determine how many daily calories you should consume in order to lose, gain, or maintain your healthy goal weight. Once you’ve reached your goal, recalculate your nutritional needs for keeping extra weight off all summer long.

To Sum 100 Calories: Spend 15 minutes biking. 5. Spend 20 minutes gardening. Keep on exercising at least 30 minutes, three days a week. Reading food labels and counting calories or writing down what and when you eat can give you more control, as well.

A. Here are some simple ways to get there.

B. Walk or run one mile.

C. A pound is 3,500 calories.

D. It is okay to have some snacks between your meals.

E. You should always make sure you get a lot of sleep.

F. Anything more than that usually means you’re troubling yourself.

G. Eat a chicken breast without the skin.
