The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(细菌)can’t get in through the skin unless it is damaged.
If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收缩),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.
When it is hot,the blood vessels expand(扩大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.
If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神经)in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.
The colour of the skin depends on special colour cells(细胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(晒黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.

The key to understand is that traffic jams don’t take as long as they seem to. It’s just that when we are in a hurry, and think we should be moving, but time appears to pass more than it does. To really show this, the next time you are stopped at a light that always seems to take forever to change, try to do something with your phone, your laptop, whatever you have available, and watch how much briefer the light seems.
When you enter a jam on the highway, reset your trip plan and care the time. Then, when you clear the jam, and are normally on your way again, care the distance of the jam, and the time it took to get through it. For my experience today, it took me 6 minutes to go 2 miles. Now, it happens to be mathematically convenient that your average speed on the highway is about 60 mph, or a mile per minute. So to estimate what time the jam actually cost you, just take your traffic jam passing time, and subtract(减去) the distance covered, which we know is a good estimate of the time it would have taken with no traffic jam. In my case, all that added up to 6-2="4" minutes.
Do this for every jam you are subjected to every time and watch how much less stressful they become once you understand how little time you are really losing.
小题1:We can infer from Paragraph 1 and 2 that ________.
A. there was no traffic jam in the past
B. modern people are under great pressure
time passes much faster during traffic jams
D. people in traffic jams are usually impatient
小题2:What does the writer suggest when caught in traffic jams?
A. Playing a trick on other drivers.
B. Figuring out how much time the jam actually cost you.
Doing some math problems.
D. Informing the boss about the delay.
小题3:The underlined phrase “subjected to” in the last paragraph probably means ________.
A. experience B. avoid admit D. control
小题4: What’s the main idea of the passage?
A. Math is closely connected with life.
B. Stress is always a bad thing.
Traffic jam is not as bad as you think.
D. There is no use complaining about traffic jams.

Having reached the highest point of our route according to plan, we discovered something the map had not told us. It was impossible to climb down into the Kingo valley. The river lay deep between mountain sides that were almost vertical(垂直).We couldn’t find any animal tracks, which usually show the best way across country, and the slopes were covered so thickly with bushes that we could not see the nature of the ground. We had somehow to break through to the river which would give us our direction out of the mountains into the inhabited lowlands.
Our guide cut a narrow path through the bushes with his long knife and we followed in single file. Progress was slow. Then, when we thought we had really reached the river, we found ourselves instead on the edge of a cliff with a straight drop of 1,000 feet to the water below. We climbed back up the slope and began to look for another way down. We climbed slipped, sweated and scratched our hands to pieces and finally arrived at the river. Happily we came downhill along its bank without having to cut our way. However, after a few miles the river entered a steep-sided gap between rocks and suddenly dropped thirty-five feet over a waterfall. There was no path alongside it and no way round it.
Then one of the guides saw a way of overcoming the difficulty. There was a fallen tree lying upside down over the waterfall with its leafy top resting on the opposite bank below the falls. Without hesitation he climbed down the slippery trunk to show us how easy it was. Having got to the fork of the tree, he moved hand over hand along a branch for four or five feet with his legs hanging in space, then he dropped onto the flat bank the other side, throwing his arms in the air like a footballer who has scored goal, and cheerfully waving us on.
74.Having reached the highest point on their route, the travelers expected to be able to .
A.track animals to the river
B.put away the maps they had been using
C.come near to the river from a different direction
D.get down to the river without much difficulty.
75.The travelers wanted to get to the river because .
A.it would lead them to the waterfall
B.it would show them which way to go
C.it was the only possible way out of the mountains
D.it was a quicker way than going over the mountains
76.One reason why the travelers took so long to get to the river was that .
A.it was too hot to move quickly
B.there was no proper path
C.they all tried to go different ways
D.they could not follow the animal tracks
77.To get past the waterfall the guide had to .
A.use a fallen tree as a kind of bridge
B.cross the river above the waterfall
C.slide down a steep river bank
D.swing across the river from a high branch

If we really want to be happy, why do we complain all the time in our daily life? We can be active in our life by setting goals and going 34 what we want. But if we’re always expressing complaints, we can not really live 35 .
If you don’t believe me, 36 how many times you complain about something or other in one day. Whether it is being stuck in traffic, being bothered by the weather, or whatever it is, there are endless 37 where you can find a reason to complain. But it’s not just outside circumstances 38 we complain about. We also complain about 39 . We complain constantly that we don’t have enough time, that we don’t have enough money and that we’re not 40 enough, cool enough, or just enough.
Most of us have experienced plenty of unpleasantness 41 complaining about things we can’t control, so do I. And I 42 really thought about it much until I found the website about “living in a complaint-free world”, which 43 my attitude towards life.
Imagine how 44 you would be if you simply stopped being a complainer. 45 of what you complain of is outside of your control anyway. 46 , it is no use thinking about something you have no power to change. When you 47 that you’re complaining, stop and ask yourself if you would rather complain, or be happy.
In our daily life, we have many choices. As Dale Carnegie puts it, any fool can criticize and complain but it takes character and 48 for the wise persons to live a complaint-free and happy life.
