At the first sight the planet Mars does not appear very welcome to any kind of life．It has very little oxygen and water,the temperature at night is below-50~Cand winds of 100 miles per hour cause severe dust storms．However,the surface of the planet seems to show that water flowed across it some time in the past,and it is believed that there is enough ice at the poles to cover the planet with water if it melts．Although there is no life on the Mars now,some scientists think that there may have been some form of life long time ago．At that time,the planet had active volcanoes;the atmosphere was thicker and warmer;and there was water．In fact,in some ways the Mars may have been similar to the Earth,where life exists.
Some people believe that the Mars could support life in the future if the right conditions were produced．The first step would be to warm the planet using certain gases which trap the Sun's heat in the planet's atmosphere．With warmth,water and carbon dioxide(二氧化碳),simple plants could begin to grow．These plants could slowly make the Mars more suitable for living．It is estimated that the whole process might take between 100,000 and 200,000 years．In the meantime,people could begin to live on the planet in special closed environments．They would provide a lot of useful information about conditions on the Mars and the problems connected with living there.
Which is the best title for this passage?A.The Possibility of Life on the Mars
B.Future Conditions on the Mars
C.The Mars and the Earth

资料：Procrastination comes in many disguises. We might resolve to tackle a task, but find endless reasons to defer it. We might prioritize things we can readily tick off our to-do list- answering emails, say- while leaving the big, complex stuff untouched for another day. We can look and feel busy. while artfully avoiding the tanks that really matter. And when we look at those rolling, long untouched items at the bottom of our to-do list, we can't help but feel a little disappointed in ourselves.
The problem is our brains are programmed to procrastinate. In general, we all tend to struggle with task that promise future upside in return for efforts we take now. That's because it's easier for our brains to process concrete rather than abstract things, and the immediate hassle is very tangible compared with those unknowable, uncertain future benefits. So the short-term effort easily dominates the long-term upside in our minds--an example of something that behavioral scientists call present bias.
How can you become less myopic about your elusive tasks? It's all about rebalancing the cost benefit analysis: make the benefits of action feel bigger, and the costs of action feel smaller. The reward for doing a pestering task needs to feel larger than the immediate pain of tacking it.
To make the benefits of action feel bigger and more real:
Visualize how great it will be to get it done. Researchers have discovered that people are more likely to save for their future retirement if they're shown digitally aged photographs of themselves. Why? Because it makes their future self feel more real-making the future benefits of saving also feel more weighty.
Which one is TRUE about our brain?A.Concrete things are more attractive than the abstract things.
B.The long term upside is easily dominated by short-term effort in our minds.
C.We cannot avoid present bias in our brain.
D.The brain can be trained to procrastinate often.

问答题Practice 3 So let us mark this day with remembrance, of who we are and how far we have traveled. In the year of America’s birth, in the coldest of months, a small band of patriots huddled by dying campfires on the shores of an icy river. The capital was abandoned. The enemy was advancing. The snow was stained with blood. At a moment when the outcome of our revolution was most in doubt, the father of our nation ordered these words be read to the people: “Let it be told to the future world… that in the depth of winter, when nothing but hope and virtue could survive… that the city and the country, alarmed at one common danger, came forth to meet [it].” America. In the face of our common dangers, in this winter of our hardship, let us remember these timeless words. With hope and virtue, let us brave once more the icy currents, and endure what storms may come. Let it be said by our children’s children that when we were tested we refused to let this journey end, that we did not turn back nor did we falter; and with eyes fixed on the horizon and God’s grace upon us, we carried forth that great gift of freedom and delivered it safely to future generations. (Barack Obama: Inaugural Address)
