Recent research suggests that if an argument gets resolved，the emotional response tied to it is significantly reduced or almost completely erased．Thus，it may be worth bringing up issues with your friends， family members，or classmates rather than holding them back．
There is a difference between arguing and fighting．Arguing is that you and your opponent present your concerns and discuss the feelings and issues related to those concerns．You can engage in an argument respectfully without stirring up（激起） anger．Fighting，however，usually involves personal attacks，raising of voices， and storming out．Discussing your issues and resolving them instead of stuffing them down can improve your emotional health．In a study，2.000 people were asked to record their feelings and experiences for eight days in a row．When people had an argument that they considered resolved， they had half the reactivity （情绪反应） of those who avoided an argument．Reactivity is an increase in negative emotions or a decrease in positive emotions．In other words，resolving an argument cuts your negative feelings by half．One day later， people who had a resolved argument reported no increase of negative emotions compared with those who avoided an argument． This means that resolving an argument can feel like you have reached a state of resolution——and you are less likely to be annoyed．
Moreover，the older you are，the more likely you will come to a resolution after an argument．This may be because more life experience usually leads to more defined priorities．You are more likely to distinguish between what matters and what does not．
It is easier to avoid a discussion，but risking talking about it may eventually lead to a better outcome．

8 . A build-it-yourself solar still(蒸馏器) is one of the best ways to obtain drinking water in areas where the liquid is not readily available. Developed by two doctors in the U.S. Department of Agriculture, it’s an excellent water collector. Unfortunately, you must carry the necessary equipment with you, since it’s all but impossible to find natural substitutes. The only components required, though, are a 5＇×5＇ sheet of clear or slightly milky plastic, six feet of plastic tube, and a container— perhaps just a drinking cup — to catch the water. These pieces can be folded into a neat little pack and fastened on your belt.
To construct a working still, use a sharp stick or rock to dig a hole four feet across and three feet deep. Try to make the hole in a damp area to increase the water catcher’s productivity. Place your cup in the deepest part of the hole. Then lay the tube in place so that one end rests all the way in the cup and the rest of the line runs up — and out — the side of the hole.
Next, cover the hole with the plastic sheet, securing the edges of the plastic with dirt and weighting the sheet’s center down with a rock. The plastic should now form a cone(圆锥体) with 45-degree-angled sides. The low point of the sheet must be centered directly over, and no more than three inches above, the cup.
The solar still works by creating a greenhouse under the plastic. Ground water evaporates (蒸发) and collects on the sheet until small drops of water form, run down the material and fall off into the cup. When the container is full, you can suck the refreshment out through the tube, and won’t have to break down the still every time you need a drink.
