People are different. Some are extrovert. These people are outgoing, confident, and know the “gift of the gab”. They also feel very comfortable when in groups of people.

Unfortunately we have the other extreme. This is the introvert. The introvert feels sick in crowds, and does not like them. These people feel awkward in the crowds, when placed in this type of situation. Many introverts are shy and lack confidence. They need to get used to people, and want to run away when questioned by people.

The introvert feels very lonely in a crowd, but this could happen to the outgoing  as well.

I think that I fall into the middle of the two kinds. Sometimes if I am comfortable about the type of people in the crowds, I feel welcome. If for some reason the crowd consists of different types of people, then I do not feel very comfortable in the crowd.

So what do I do when I suddenly feel lost and alone in the crowd? I try to calm my mind by taking deep breath and telling myself that even this will pass. I then try, and get away from the crowd by making excuses or even trying to get to my car and go home. This, of course, is a poor excuse and doesn’t often work well. These are excuses that are employed. The ones that I am not so proud of are acting like I have an emergency to go to. This is a very good lie, but I feel really bad afterwards.

I have tried this one, and have succeeded. I try and find someone who feels just like I do. I then try and make a new friend. Sometimes this works and sometimes it does not. This is quite a noble way of staying in the crowd.

小题1:What is the best title of the passage?

A.What is the character of the introvert?

B.Why do people feel lonely in a crowd?

C.How can we make ourselves calm down in a crowd?

D.What do you do when you suddenly feel lonely in a crowd?小题2:The word “extrovert” is most likely to mean ______.

A.serious

B.excited

C.outgoing

D.nervous小题3:From the fourth paragraph we can infer that _____.

A.the writer is good at getting along with others

B.the writer does not like to deal with people from other regions

C.the writer sometimes does not feel very comfortable in the crowd

D.the writer has double personality when faced with different types of people小题4:When the writer feels lonely, he prefers to calm down by _____.

A.making a call

B.making excuses

C.holding his breath

D.deep breathing

答案

小题1:D

小题2:C

小题3:C

小题4:D

题目分析:如何去应对在众人面前突如其来的孤独感、失落感呢?这种情况不仅会发生在性格内向的人身上,有时候性格外向的人也会有如此的感觉。作者通过自己的亲身体会给人们提供了很好的建议。比如做深呼吸,在心里反复告诫自己一切都会过去或者找个借口离开那种场合等待。

小题1:D主旨大意题。文章开头提出两种性格不同的人,然后提出自己偶尔会遇到的尴尬情况,接着提出“So what do I do when I suddenly feel lost and alone in the crowd?”,再就这个中心问题提出自己的应对方法,所以文章中心话题即为“如何去应对突然的孤独感”,故D选项正确。

小题2:C词义猜测题。从文章开头These people are outgoing, confident, and know the “gift of the gab”.对这些人的描述可以判断extrovert是指性格外向的人。所以正确答案是C。

小题3:C细节理解题。文章第四段提到then I do not feel very comfortable in the crowd.,由此可知作者有时在人群中会突然感觉不自在,所以C选项正确。

小题4:D细节理解题。I try to calm my mind by taking deep breath and telling myself that even this will pass.从文章第五段可知作者感到不自在的时候会通过深呼吸来调整自己状态,使自己平静下来。

实验题

(1).在做“用单摆测定重力加速度”的实验时:

①需要测量摆球直径,如图1所示,摆球直径为_______cm;让刻度尺的零点对准摆线的悬点,摆线竖直下垂,如图2所示,那么单摆摆长是_______。

②为了提高实验精度,在实验中可改变几次摆长L并测出相应的振动周期T,从而得出几组对应的L与T2的数据,如图所示。再以L为横坐标,T2为纵坐标,将所得数据连成直线,并求得该直线的斜率为k。则重力加速度g=_______。(用k表示)

(2).某实验小组利用实验室提供的器材探究一种金属丝的电阻率,所用器材包括:输出为3V的直流稳压电源、电流表、待测金属丝、螺旋测微器(千分尺)、米尺、电阻箱、开关和导线等。

①他们截取了一段金属丝,拉直后固定在绝缘的米尺上,并在金属丝上夹上一个小金属夹,金属夹可在金属丝上移动。请根据现有器材,设计实验电路,并连接电路实物图4

   

②实验的主要步骤如下:

A.正确连接电路,设定电阻箱的阻值,开启电源,合上开关;

B.读出电流表的示数,记录金属夹的位置;

C.断开开关,_______,合上开关,重复B的操作。

③该小组测得电流与金属丝接入长度关系的数据,并据此给出了图5的关系图线,其斜率为_______(保留三位有效数字);图线纵轴截距与电源电压的乘积代表了_______电阻之和。

④他们使用螺旋测微器测量金属丝的直径,示数如图6所示. 金属丝的直径是_______。图5中图线的斜率、电源电压金属丝横截面积的乘积代表的物理量是_______。
