中华龙舟大赛中龙舟上运动员相对于岸上观众是        的,相对于        是静止的;运动员用力把浆向后划,龙舟却向前前进,这说明物体间力的作用是        的;运动员越用力击鼓,鼓声的       越大(响度/音调).

答案

运动   龙舟  相互   响度

题目分析:(1)以“岸上站立的观众”为参照物,龙舟与观众之间的位置发生了变化,所以龙舟是运动的;以“鼓”(或船)为参照物,运动员与鼓(或船)之间的位置没有发生变化,因此是静止的.

(2)因为力的作用是相互的,运动员用桨向后划水(给水向后的作用力),水给桨一个向前的反作用力,所以龙舟就向前运动.

(3)运动员越用力击鼓,鼓面振动的幅度越大,鼓声的响度就越大.

所以答案为:运动;鼓(或船);相互;响度.

点评:(1)判断龙舟的运动状态,关键看它与所选的参照物“岸上站立的观众”和“鼓”之间的位置是否发生了变化;

(2)运动员用桨向后划水,给水一个向后的作用力,根据力的作用是相互的,水就给桨一向前的作用力,使船前进;

(3)声音的响度指的是声音的大小,是由振幅和距离发声体的远近决定的.

Moving to a new neighborhood,town,state,or even country can be a pretty scary  experience.All you know is that things will be different and chances are you won’t know the kids  at your new school.

The experiences that go with moving make many kids feel nervous and worried.This is perfectly normal but don’t let these emotions overrun your thoughts!You will soon get used to your surroundings and find new friends at your new school.

Leaving old friends and familiar places behind can be difficult.However,as you begin the moving process,keep in mind that saying goodbye to your old house,school,and friends does not mean that you have to forget them or that your farewell is permanent!If you’re moving to a new state or even a different country and won’t see your friends for a long nme,don’t despair.Make sure to ask everyone for their address so you can write them letters.Also,thanks to the  Internet,it is very easy to stay in touch through email or instant messaging technologies.With  your parent’s permission,you can even create a blog or web page to chronicle all of your new  experiences.Include your thoughts,tales of your new adventures,even pictures of new friends,your new house,and new town.Your old friends will love seeing what you are busy with.

Many schools have an orientation program where a student already established at the school shows a new student around for their first week.This can help you to find your way around the school and to make new friends faster.

While moving is tough on kids of any age,high school counselor Karen Turner says moves can be particularly difficult for teens.“I think moving during adolescents is an extremely stressful experience,especially if you are into your junior high or senior year.Students tend to have established a very strong peer network during that period in their lives.Often this has more influence on them even than their families in some cases,and when they are torn from that there’s often resentment (怨气).” However,Turner adds that while moving isn’t easy,there are things that your parents and the school can do to help you cope with the change.
