你来经历一次小宇和小青的探究过程吧．小宇以一定速度将石子向斜上方抛出，石子所做的运动叫斜抛运动，他想怎样才能将石子抛得更远呢？于是他找来小青一起做了如下探究：他们用如图甲所示的装置来做实验，保持容器水平，让喷水嘴的位置不变，用开关控制水喷出的速度．

①首先让喷水嘴的方向不变（即抛射角不变）做了三次实验：第一次让水的喷出速度较小，这时水喷出后落在容器的A点；第二次，让水的喷出速度稍大，喷出后落在容器的B点；第三次，让水的喷出速度最大；水喷出后落在容器的C点．小宇和小青经过分析得出如下结论：在______一定时，当物体抛出的______越大，抛出的距离就越远．

②然后控制开关让水喷出的速度不变，让水沿不同方向喷出，如图乙所示又做了几次实验，得到如下的数据：

喷嘴与水平方向的夹角	15°	30°	45°	60°	75°
落点到喷嘴的水平距离/cm	50	86.6	100	86.6	50

小宇和小青对上述数据进行了归纳分析，得出的结论是，在抛射速度一定时，随着物体抛出时与水平方向夹角的增大，抛出距离的大小变化关系是______，当夹角为______时，抛出距离最大．|

③小宇和小青总结了一下上述探究过程，他们明确了斜抛物体在水平方向上飞行的距离与______和______有关，他们感到这次探究的成功得益于在探究过程中两次较好地运用了______法．

Study Tips and Techniques

If you often find yourself struggling with your studies, here are some useful study tips and techniques that can help you out …

It is a common misconception that self-study can begin only after a particular topic or chapter is taught in class. You should start preparing for the class in advance. After attending the classes, it is of great importance that you have time to review the notes that you have taken during the class as well as try and read more about the subject on your own. Be it reference books, or e-books, try and hunt for more information about your subject so that you have a comprehensive view of the topics. Often while reading and self-studying, it happens that you come across doubts or questions that did not occur to you in the classroom. Try and answer these questions yourself with the help of books or the Internet, however in case you fail to answer, write down these questions so that you remember to clarify the questions in your next class.

62._____________

Yes, one of the important habits that one must acquire to enhance the studying process is involve themselves in group discussions about the subjects that you are studying. Group discussions can be a great way to broaden your viewpoint over important issues since group discussions give every group member a chance to voice their understanding , which might not necessarily be alike. Group discussions are thus a healthy and a rather informal way of exchanging information and discussing issues. Many teachers encourage the group discussion technique in their classroom as well.

63.______________

No matter how much people disapprove of the process and the timetables, it is a known fact that having a clear and detailed project makes it easier for a person to reach the goal. According to your convenience, map out your daily/weekly/monthly study. It is always better to have a weekly or a daily arrangement, so that abrupt changes in class schedules or any other changes can be taken into consideration accordingly.

64._____________

Yes, there exist some species of students who burn the midnight oil. The studying process should be such that it leaves enough room for a student to join in entertainment activities and relaxation. Always chalk out a schedule that will not influence your sleep, your health, your sport/ entertainment activities and other routine tasks. Also studying a single subject at a stretch ( like an entire week or so ), can get boring, for this reason plan a schedule that helps your switch from one subject to another in enough time.

65.____________

Normally students get too caught up with the grades, the percentage and the entire marking system. Always remember that if you study with the aim of acquiring knowledge, the grades will  be brighter. However if you just aim for the high grades, there is a chance you might get the grades, but you will miss out on acquiring comprehensive knowledge on a particular subject. Always study with the right point of view, and you will never have to worry about your grades. Knowledge is way beyond the grades.
