The summer is so hot and sticky, why would we want to sweat even more by exercising? Or is it just I who think like that? Sweat and clothes sticking to our bodies as we move make exercise seem rather uncomfortable. What can be done to fix it?
Researchers at MIT have come up with a solution. They’ve developed a workout suit with flaps that open as the wearer begins sweating. As the person cools off, the flaps shrink until they assume their original position.
Sounds cool, sounds practical. These flaps are lined with live, microbial ( 微生物的)cells. These cells can detect when the body is heating up too much, and in response, expand. It’s just as if they were working within any other organism, recognizing patterns of heating and cooling, then responding appropriately to maintain body temperature. It seems kind of strange to have living cells (that aren’t your own) on you, right? Not to fear, these cells have been believed safe. Plus, there’s a material in the suit that helps the flaps/cells hover ever so slightly above the exerciser's skin. The flaps start opening as soon as people start feeling warm and sweaty, and the bit of space between the suit and the skin helps develop that feeling of cool and refreshing air as they move.

According to Gadgetify.com, researchers have also been working to apply this technology to running shoes as well. Moisture-responsive workout clothing has the potential to revolutionize sport fashion industry. People can stay drier, cooler and fresher at the end of the workout, which sounds better than leaving the gym with a trail of sweat and a red face. It’s possible that the comfort of these suits can make people enjoy exercising more and exercise with more intensity.

The African elephant,the largest land animal remaining on earth,is of great importance to African ecosystem(生态系统).Unlike other animals,the African elephant is to a great extent the builder of its environment.As a big plant-eater,it largely shapes the forest-and-savanna(大草原) surroundings in which it lives,therefore________of existence for millions of other animals that live in its habitat(栖息地).
It is the elephant’s great desire for food that makes it a disturber of the environment and an important builder of its habitat.In its continuous search for the 300 pounds of plants it must have every day,it kills small trees and underbushes,and pulls branches off big trees.This results in numerous open spaces in both deep tropical forests and in the woodlands that cover part of the African savannas.In these open spaces are numerous plants in various stages of growth that attract a variety of other plant-eaters.
Take the rain forests for example.In their natural state,the spreading branches overhead shut out sunlight and prevent the growth of plants on the forest floor.By pulling down trees and eating plants,elephants make open spaces,allowing new plants to grow on the forest floor.In such situations,the forests become suitable for large hoofed plant-eaters to move around and for small plant-eaters to get their food as well.
What worries scientists now is that the African elephant has become an endangered species.If the elephant disappears,scientists say,many other animals will also disappear from vast areas of forest and savanna,greatly changing and worsening the whole ecosystem.

(NEW YORK) A French tourist highly praised for rescuing a two-year-old girl in Manhattan said he didn’t think twice before diving into the freezing East River.
Tuesday’s Daily News said 29-year-old Julien Duret from France was the man who left the spot quickly after the rescue last Saturday.
He lifted the little girl out of the water after she fell off the bank at the South Street Seaport museum. He handed the girl to her father, David Anderson, who had dived in after him.
“I didn’t think at all,” Duret told the Daily News. “It happened very fast. I reacted very fast.”
Duret, an engineer on vacation, was walking with his girlfriend along the pier(码头) when he saw something falling into the water. He thought it was a doll, but realized it was a child when he approached the river. Immediately, he took off his coat and jumped into the water.
When he reached the girl, she appeared lifeless, he said. Fortunately, when she was out of the water, she opened her eyes.
Anderson said his daughter slipped off the bank when he was adjusting his camera. An ambulance came later for her, said Duret, who was handed dry clothes from onlookers. Duret caught a taxi with his girlfriend shortly after.
The rescue happened on the day before he left for France. Duret said he didn’t realize his story of heroism had greatly moved New York until he was leaving the city the next morning.
“I don’t really think I’m a hero,” said Duret. “Anyone would do the same thing.”

Customer Reviews
1. ★★★★★
My favorite shoes! I’ve been to many conferences where my business fellows have told me how much they like my shoes. Just wearing them makes me feel more calm and content in the office. I recommend them to all of my co- workers, and I own a pair of each color.
2. ★
These are the worst shoes I have ever worn! The leather came off after only one week, and everybody thought they were ugly. The bottom of the shoes made everything slippery. My employer fired me because he hated them! From then on, I will only wear Brand X shoes !
3. ★★★
These shoes do exactly what shoes are supposed to do. There isn’t anything too special about them. In the morning, I put them on and go to work. They look delightful enough , and they are quite durable. I will probably buy another pair.
4. ★★★★
These shoes are my most cherished(珍爱的) possession. I met my bride while buying a pair of these shoes. She was the saleswoman at the store I bought them at , and after she sold me three pairs, I asked her for her phone number and we started dating. Soon after that, we were engaged. We are getting married this afternoon, and I couldn’t be happier.

阅读下面短文，根据所给情节进行续写，使之构成一个完整的故事。
School mornings were always busy. The first sentence I usually heard was, “It’s time to rise!” It was Mom’s loudest voice and there was no way I could pretend not to hear it or hide from it.
“Okay, Mum. I’m getting up and dressed!” I would manage to call back.
Mum spoke loudly again as she announced, “Breakfast is ready!”
By then, I couldn’t get to the kitchen fast enough. In fact, it was a race between my sister, my brother, and me. We usually seated ourselves at the same time, sometimes knocking each other out of our places. After breakfast, we all rushed out to the bus stop as we took our lunch bags that contained a sandwich, fruit and dessert.
Then, one day, much to my surprise, there was no dessert in my lunch! What could have happened to it? Did Mom forget to make or buy it? Oh, well, I thought. It’s only one time, so it’s no big deal. But, for the next few days, my lunch contained no dessert! So one day, after school, as soon as I got home, I asked, “Mum! Why haven’t you been putting a dessert in my school lunches?”
Mum answered, “Why, Eugene, I have been including a dessert in your lunch. If you ‘re not getting them, then who is?”
So then we thought of my activities and what I did with my lunch each day. As soon as I arrived at school, I always put my lunch in the classroom closet (储物间) along with all of the other lunches. And that brought us to Carl the bad boy of the third-grade classroom. The teacher didn’t like him in class and would send him to the closet, where he would spend most of each day.
Carl lived in a group of foster home (集体寄养之家). He was loud and somewhat of a thief, he would take just about anything that wasn’t fastened down, so he wasn’t welcome at school. Mom and I concluded that with nothing else to do Carl was probably going through the lunches and eating what he liked.
