But there is now also a Chinese department. It is the largest department in the college. There are over 75 students in each grade and we have about 45 teachers. The teachers in the English department are from different countries, mainly from the USA and Canada, with a few from England and Australia. You’ll have all your classes here in this building. Now, let’s walk over to the main library which is the largest building in the college just next to the English department building.

One possible version :
Learn to smile
Smile is an attitude to life. In our life, there may be something unpleasant. For example, you fail in an exam; or another time, you are misunderstood by your friends. These unpleasant things may make you feel bad. Then what will you do? Why not learn to smile? Smiling to yourself can bring back your confidence. Sometimes, the greatest enemy is yourself. That is to say, sometimes you are beaten by yourself. We should also learn to smile others. It will help us to get closer to others. So, smile is the most widely used language in our life.

学习需要不断的在练习中积累,接下来是读文网小编为大家带来的初三年级下册语文期中考试测试题及答案,供大家参考。
一、语文基础知识及应用
1、tuíhèdàizā虔懦畜槛
2、查──杳辨──辩急──疾密──蜜诧──姹
兴──欣鹰──膺遗──逸
3、A──DB──FC──GE──H
4、尊严就是飞翔。
5、⑴他的作文不但常常居全班之冠,而且在全校冒尖。
⑵我们要学习“海空卫士”王伟同志英勇无畏的精神。
⑶社会主义国家发展生产力的根本目的是提高人民的生活水平。
6、提示:两句都有语病,第一句是前后矛盾。第二句是“特别”应该有针对性。
7、C
二、现代文阅读
(一)
8、鲁迅《孔乙己》《狂人日记》小说封建科举制度和封建文化
9、穷自命清高,显示自己与短衣帮不同身分特殊
10、懒穷
11、常受欺凌爱面子,掩饰错误自欺欺人迂腐可笑
12、B
13、D
14、D
15、B
16、CD
17、略
(二)
18、⑴某天
⑵孤儿院市场
⑶男孩、院长
⑷男孩对自己的生命很悲观。
⑸男孩照院长的吩咐拿一块石头到市场去卖,但不论别人出多少钱,绝对不卖,石头被传扬成“稀世珍宝”。
⑹男孩受到教育:自我珍惜,生命就有意义。
19、D
20、“总”与上文的“常常”相照应,说明男孩对自己的生命极其悲观,内心非常痛苦。
21、不能去掉,因为“竟”表示出乎意料,说明这块石头极其普通,由于对它的珍惜使它身价倍增,这是男孩没有想到的,恰是院长的用心所在,“竟”很好地突出了文章中心
22、因为“卖”是用东西换钱,前两次到市场上去卖,是因为石头可用钱衡量它的价值,而到宝石市场时,它已成宝石,不能用钱衡量石头的价值,它也就被传为“稀世珍宝”
23、一块不起眼的石头,因为你的珍惜、惜售而提升了它的价值,就成了稀世珍宝。
启示(略)。
