If you find that your teacher is unfair to you, think about what is happening. Try to find out whether your teacher really dislikes you, or whether something else is going on. Here are some questions to ask yourself:

1. Ask your classmates if they are having trouble with the teacher, too. If they say yes, perhaps your teacher is to blame.

Are you working up to your ability? Maybe you got a C in your last test, and your teacher told you that you could do better. And the kid sitting beside you got a C, too. 2. Isn’t this unfair? Well, it could be that your teacher knows that you could do better if you put more effort into it. 3. .

4. There’s nothing wrong with being sensitive (敏感的) ,but if you react to criticism quite differently from others, this could be a reason why you think your teacher doesn’t like you.

Does your teacher seem to act unfairly all the time, or just once in a while? Think about the harsh (苛刻的) things your teacher has done to you. Are these things happening every day, or just once or twice a month? If your teacher really hates you, you would probably be picked on all the time. 5. .

A. Are you the only person being treated badly, or is your teacher rough on the whole class?

B. Are you getting along well with your classmates?

C. Are you more sensitive than other students?

D. Are you interested in your lessons?

E. If your teacher has acted unfairly only a few times, then there’s probably something else going on.

F. Teachers often grade students by different standards.

G. But the teacher didn’t say anything to him!

D

Mars(火星)appears to be flowing with small streams of salty water,at least in the summer,scientists reported Monday.“It suggests that.it would be possible for there to be life today on Mars,”NASA's science mission chief,John Grunsfeld,said at a news conference on September 28,2015.

The streams are about 12 to 15 feet wide and 300 feet or more long,scientists said.“What we're dealing with is wet soil.thin layers of wet soil,not standing water,”said Aifred McEwen of the University of Arizona at Tueson!the principal scientist for the Mars Reconnaissance Orbiter's high-resolution imaging experiment.

Because liquid water is essential to life,the findings could have major implications for the possibility of Martian life.The researchers said further exploration is needed to determine whether microscopic life exists on the planet.

The presence of liquid water could also make life easier for astronauts visiting or living on Mars.Water could be used for drinking and for creating oxygen and rocket fuel.NASA's goal is to send humans there in the 2030s.

The evidence of flowing water consists largely of dark,narrow streaks(条痕) on the surface that tend to appear and grow during the warmest Martian months and fade the rest of the year.

Mars is extremely cold even in summer,and the streaks are in places where the temperature is as low as minus 10 degrees Fahrenheit.But salt can lower the freezing point of water and melt ice.

The source(源头)of the water is a mystery.Scientists noted it could be melting ice.It could be an underground aquifer,which is rock or sand that can hold water.It is possibly water vapor from the thin Martian atmosphere,Or it may be a combination Michael Meyer,lead scientist for NASA's Mars exploration program,said the only definitive way for now to determine whether there's life on Mars is to collect rocks and soil for analysis on Earth - something a U.S.lander set for lift-off in 2020 will do.
