9. University was an important period for him, (那时他每天都去图书馆) .
Three years ago when I was just a freshman in high school,the busy spring season was approaching quickly. I was al?ready preparing to play the saxophone (萨克斯) in my school's pit orchestra for the musical that year,for state solo and ensemble (合奏) ，and softball tryouts (选拔赛〉were just around the corner.
It was only the second day of tryouts―a Tuesday. Adults were hitting popups in the outfield as a drill (训练) .The drill was poorly set up,however,as two lines were formed in both the right and left outfields,the adults hit fly balls from the line towards'the centre field. When it was my turn,I stepped up and the ball was hit. I turned and started to run back,but soon realized the ball was hit too hard for me to catch. I turned around to run and get it ..-Then I recall waking up on the ground. As it turns out,when I turned to retrieve (取回) the ball,I ran into anoth?er player,my front teeth piercing her forehead. As one could imagine,I was horrified!My right front tooth was very loose and about to fall out. With the musical only four days away and state solo and ensemble a week away,it was vexatious！
After going to the dentist and getting my tooth fixed,I went home and to bed after taking the prescribed pain?killers. That Friday* Saturday,and Sunday,I performed in the musical. I also went to state solo and ensemble the week after and received a one (the best score one can re?ceive) ，regardless of the pain and discomfort I endured. I was determined to do what I love―play music―and I did.

Most of us are used to seasons. Each year,spring follows winter,which follows autumn,which follows summer,which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience. Between 65,000 and 35,000 years ago,the planet was much colder than it is now. During that time the temperature also changed a lot? with periods of warming and cooling. Ice mel?ted during the warm periods,which made sea levels rise. Water froze again during the cold periods.
A new study fromSwitzerlandmakes it clear where ice sheets (冰川) melted during the ice age. It now seems that the ice melted at both ends of the earth,rather than just in either northern or southern regions.
This surprised the researchers from the University of Bern. Scientists have long assumed that most of the ice that melted was in the northern hemi?sphere (半球) during the 30,000-year long ice age. That belief was held because the north pole is surrounded by land,while the south pole is surrounded by the Antarctic ocean. It is easier for ice sheets to grow on land. If surrounded by sea the ice can easily just slip into the ocean instead of building up.
The researchers used a computer model to look at ways the ice could melt and how it might affect sea levels. They compared these results to evidence of how temperatures and currents actually changed during that time. The model showed that if it was only in the northern hemisphere that ice melted,there would have been a bigger impact (影响) on ocean currents and sea tempera?tures than what actually happened. Studies suggest that melting just in the southern hemisphere would have been impossible,too. The only reasonable conclusion,the scientists could make,was that ice melted equally in the north and the south.
It is still a mystery as to what caused the temperature changes that caused the ice to melt.
