1 . Four teams of mountaineers set out on a race to conquer(征服) an unclimbed mountain peak in the Himalayas. The Canadian team chose a long, but safe route, while the British, Chinese and Russian teams chose a faster but steep and dangerous route up the mountain.

When night fell, the teams made camp on the mountainside. But the next morning, the sun rapidly rose air temperature and the strong wind caused a heavy snowfall, which led to a terrible avalanche. The disaster struck and some members of the British, Chinese and Russian teams were swept away and killed. But the Canadians didn’t know what had happened.

It was an hour after the disaster and there was no hope of finding any survivors. The leaders of the British, Chinese and Russian teams, met to discuss how to successfully keep all the survivors alive.

	Britain	Russia	China
Members	3	2	2
Tents	1 two-man	None	1 four-man
Sleeping bags	3	2	2
Rope	25 metres	50 metres	None
Food	1 person for 3 days	2 people for 4 days	2 people for 2 days
Medicine	None	None	None

2 . One major reason Americans don’t get enough exercise is that they feel they don’t have enough time. It can be difficult to squeeze in the 75 minutes of aerobic (有氧的) exercise per week that federal guidelines recommend.    1    .

In a new analysis of 14 studies, researchers tracked deaths among more than 232,000 people from the U.S., Denmark, the U.K. and China over at least five years, and compared the findings with people’s self-reports about how much they ran. People who said they ran any amount were less likely to die than those who didn’t run at all.    2     This was true even for those who didn’t log a great deal of time. The analysis divided people into groups, with 50 minutes or less per week representing the group that ran the least―but still ran. ‘‘Regardless of how much you run, you can expect such benefits,” says Zeljko Pedisic, one of the authors of the new analysis published in the British Journal of Sports Medicine.

The analysis is the latest to illustrate the benefits of running on the human body. It’s what we evolved (进化) to do.     3     But as leisure-time exercise, running keeps us healthy. “One of the best ways to avoid having to see a doctor,” Zeljko says, “is to stay physically active.”

    4     Running is good at guarding against cancer partly because it uses up blood sugar, starving the cancer cells that rely on it for fuel. And it protects you in other ways not necessarily measured in the latest research: by decreasing inflammation (炎症), for example, which is at the root of many diseases, and stimulating the production of a protein that improves brain health.

    5     Neither were how often people ran and the pace they kept. As long as you’re running, more isn’t always better, especially given that the risk of injury increases with repetition.

A．People may no longer hunt wild animals for their next meal.

B．The physical demands of running affect our body in a beneficial way.

C．Some people run to prevent disease, and others run because it makes them feel better.

D．Runners were 27% less likely to die for any reason, compared with nonrunners.

E．But researchers point out, to infer something like that, they need the whole population measured.

F．But new research suggests people may be able to get life-lengthening benefits by running for far less time.

G．The good news is that running more than 50 minutes per week wasn’t linked to additional protections against dying.

The big day had finally arrived. I had won the local speech contest (比赛), representing Madison Middle School. Here it was the state competition. I waited backstage for the host to announce My name.

Even though I had practiced much, I was extremely nervous. My heart was thumping, my palms were sweating, and my mouth was dry. “Calm down,” I told myself. Still, picturing an audience of teachers, parents and classmates made me want to disappear totally.

Mr. Patrick, who taught me to give speeches, reminded me, “You’ll do great. You’re prepared. You’ve come this far.”

Mr. Patrick was right. I was ready for this, and besides, I won first place in the earlier contests. Yet, when I pictured all eyes on me waiting for me to mess up, my heart was gradually sinking into my stomach.

“You can’t back out now,” I told myself as Mr. Nichols, the host, announced my name and the title of my speech, “My Hero.”
请你写出接下来主人公演讲的过程，以及演讲结束后激动的心情。

The big moment came.
