In the early days of sea travel, seamen on long voyages lived exclusively on salted meat and biscuits. Many of them died of scurvy (坏血病), a disease of the blood which causes swollen gums (牙龈), livid white spots on the flesh and general exhaustion. On one occasion, in 1535, an English ship arrived in Newfoundland with its crew desperately ill. The men’s lives were saved by Iroquois Indians who gave them vegetable leaves to eat. Gradually it came to be realized that scurvy was caused by some lack in the sailors’ diet and Captain Cook, on his long voyages of discovery to Australia and New Zealand, established the fact that scurvy could be prevented by the supply of fresh fruit for the sailors.
Nowadays it is understood that a diet which contains nothing harmful may yet result in serious disease if certain important elements are missing. These elements are called “vitamins”. Quite a number of such substances are known and they are given letters to identify them, A, B, C, D, and so on. Different diseases are associated with shortages of particular vitamins. Even a slight lack of Vitamin C, for example, the vitamin most plentiful in fresh fruit and vegetables, is thought to increase significantly our susceptibility (敏感度) to colds and influenza.
The vitamins necessary for a healthy body are normally supplied by a good mixed diet, including a variety of fruit and green vegetables. It is only when people try to live on a very restricted diet, say during extended periods of religious fasting (斋戒), or when trying to lose weight, that it is necessary to make special supply to make up for the missing vitamins.
1.Scurvy is a disease that is caused by .
A.salted meat and biscuits B.exhaustion

2.To avoid such disease as scurvy, it’s better for us .

A.vitamin pills are of no use
B.nutritious food might be unhealthy

I remember him on his first day in the sixth grade. He was the only black face in a sea of white. A few days later, he had yet to connect with anyone. Our teacher asked me to talk to him. So I went over to him and said, “Hi.” He replied, “Hi.” 1. The next day, “What’s up?” “Not much.” We added a word or two each day until full sentences were formed, and then a paragraph.
Soon we became good friends and our friendship survived new friendships and small arguments. 2. When it was my turn, I expressed criticism of his choice of clothing. He was laughing as hard as I was.
Strangely enough, I remember so much about that day except in what context (语境) the N-word (rude word for a black person) was used. 3. He was my best friend. But the look on his face told me otherwise.
It was a few days before we spoke again. Although we insisted we’d be friends forever, I never saw him after high school. It may not have had anything to do with what I said, or it may have had everything. 4.
Several days ago, there was a near race riot (暴动) during a high school basketball game, and angry teenagers shouted several rude words. 5. All I wonder is if these kids will ever feel as bad as I did for using such a rude word. It’s a curse word, but the real curse is on the person who uses it.
A. And that was it for day one.
B. Later that year, we were leaving school.
C. My purposes were not to wound him obviously.
D. These words brought back a flood of memories.
E. By that point, we weren’t close enough for me to ask.
F. One day, with nothing better to do, we played jokes on each other.
G. At our senior graduation party, we made a point of toasting each other.

2. Look at the schoolboy in the photo. From his colorful traditional dress, other people in Peru know he comes from the Quechua community. We wear uniforms at school and work, and we dress in our favorite sports team colors to say the same thing: 3.
And now look at the Huli villager in the photo, who is getting ready for a local festival. He’s applying the traditional colors of red, black and white to his own personal face pattern. Face-painting is an important part of the celebrations. These days people are starting to experiment with brightly colored paints as well as traditional colors. In fashion-conscious Europe, the “in” color changes every season. 4.

It was on the early afternoon of a mid-October day in 2012. Bismark Mensah, who came to America several months ago, was collecting carts (手推车) outside a Walmart in Federal Way. It was a part-time job for him. He earned $9.05 an hour in charge of getting carts out of the parking lot.
He was used to finding stuff in carts that customers had somehow forgotten — keys, credit cards, wallets. And he turned them into a customer service. But a particular item stood out. It was a white envelope with a clear window in the middle, and there was a lot of cash in it, around $20,000. Mensah turned them into customer services.
Because of what he did that afternoon, Mensah is now the winner of Walmart’s national 2013 “Integrity(正直) in Action Award”.
Bismark Mensah says that since the story ran, he has become the model the youth in Ghana (his native country).

It had been a long,hard,wonderful day.The two of us had walked from the sea’s edge through the length of a beautiful valley,climbed a superb mountain,travelled its narrow,rocky ridge(山脊),and now stood on its final peak,tired,happy and looking for the perfect campsite.
The experienced backpacker has a natural feeling for such things,and our eyes were drawn to a small blue circle on the map,like an eye winking at us.We could not see it from where we were,but we followed our judgement and went down steeply until it came into view.
We were right.It was a calm pool,with flat grass beside it.Gently taking our packs off,we made the first of many cups of tea before pulling up our tent.Later that evening,over another cup of tea and after a good meal,we sat outside the tent watching the sunset over a sea dotted with islands,towards one of which a ferry was slowly moving.It is not always so perfect,of course.On another trip,with a different companion,a thoroughly wet day had ended at a lonely farm.Depressed at the thought of camping,we had knocked and asked if we could use a barn(谷仓) as a shelter.
Backpacking could be defined as the art of comfortable,selfsufficient(自给自足的) travel on foot.Everything you need is in the pack on your back,and you become emotionally_as_well_as_physically_attached_to_it.I once left my pack hidden in some rocks while I made a long trip to a peak I particularly wanted to climb.I was away for nearly three hours and ended up running the last stretch in fear that my precious pack would not be there.It was,of course.
The speed at which the backpacker travels makes this the perfect way to see any country.You experience the landscape as a slow unfolding scene,almost in the way it was made;and you find time to stop and talk to people you meet.I’ve learned much local history from simply chatting to people I met while walking through an area.At the end of a trip,whether three days or three weeks,there’s a feeling of achievement,of having got somewhere under your own power.
After years of going out walking just for the day,many people start backpacking simply through wanting to stay out rather than cut short a trip.
1.The writer and his companion knew there was a pool because ________.
A.they had been told about it
B.they could see it on the map
C.they had seen it earlier in the day
D.they could see it from the top of the mountain
2.What does the underlined word “it” in Paragraph 2 refer to?
A.The map. B.The pool.
C.The mountain. D.The campsite.
3.How did the writer and his companion feel at the end of the day?
A.They were too tired to put up their tent.
B.They wished they could have found a farm.
C.They were anxious about the coming weather.
D.They were delighted with the spot they’d found.
4.What does the writer mean by being “emotionally as well as physically attached to it ” in Paragraph 4?
A.It is more than just a practical aid.
B.He walks better when he is wearing it.
C.It is not a good idea to leave it anywhere.
D.He might die on the mountains without it.
