We live on a corner, higher than street level. There is a rock wall 2 our yard. But at the edge(边缘) of the yard, some rocks were thrown up onto the ground as if someone were in a hurry to 3 . We called this area our “rock garden”. The “rock garden” looked so boring that whenever we planted flowers or plants, Denise or I would stick them out(伸出去) to bring some 4 to the area.Last summer I reached the end of the garden and found a tiny little 5 that I could not immediately make sure what it was, I knew I didn’t plant it and Denise claimed that she didn’t either. We decided to let it continue growing 6 we could tell what it was.Weeks passed and as I made my way back to the 7 plant, it turned out to be asunflower(向日葵). It had a tall skinny stalk and only one head on it. I decided to 8 it and get the weeds(杂草) around it away. As I moved away the rocks from the area, I noticed something9 . The sunflower had not started where I saw the stalk begin. It actually had begun under a big rock and grown under and around it to reach the 10 .That’s when I 11 that if a tiny little sunflower didn’t let a big rock stand in its way of developing, we should have the 12 of doing the same thing, too. Once(一旦) our environment begins to see that we believe in ourselves like that little sunflower, we can get the same nourishment(营养) and growing up as well.We need to believe in ourselves knowing we have the abilities in 13 our dreams. Like the sunflower, it knew it had the abilities to get out of the difficulty because it trusted in the Universal Truth(普遍真理) and believed it would 14 .Stand tall like the sunflower and be proud of who and what you are and the environment will begin to 15 you.

The King of this country(which was called Lilliput)had ordered his people to carry me to the capital city,about a kilometre away.I made signs to ask whether(是否) I could be untied,but the official politely said “No”. While I was eating bread,a platform had been prepared to carry me. The people of Lilliput,known as the Lilliputians,are very clever with their hands.For me,five hundred men built a special wooden platform with twenty-two wheels. Nine hundred of the strongest men worked for about three hours to lift me on to the platform,and one thousand five hundred of the King's largest horses (each eleven and a half centimetres high)pulled me to the capital.I did not know about any of this,because they had put a sleeping powder in my wine,and I was in a deep sleep.(An Extract from A voyage to Lilliput )( ) 1.

According to(根据) the extract, what did the Lillipu tians do with “I”?A. The official set “I” freeB. They only gave bread to “I”C. They used a platform to carry “I”D. They built a wonderful chair for “I”BMr. Grey was the manager of a small office in London. He lived in the country, and went to work by train. He liked walking from the station to his office if it wasn’t raining, because it gave him some exercise.One morning he was walking along the street when a stranger stopped him and said to him, “You may not remember me, si r, but seven years ago I came to London without any money in my pockets. I stopped you in this street and asked you to lend me some money and you lent me£5, because you said you were always ready to take a chance to give a man a start on the way to success.”Mr. Grey thought for a few minutes and then said, “Yes, I remember you. Go on with your story!”“Well,” answered the stranger, “Would you like to take another chance?”( )1.

2021届高考地理一轮总复习测试卷5:地球公转及其地理意义含解析
2021届高考地理一轮总复习测试卷第五讲地球公转及其地理意义(2019·宁夏育才中学模拟)二十四节气是中华民族古老文明和智慧的结晶,现已正式列入联合国教科文组织人类非物质文化遗产名录。
读二十四节气示意图,回答1~2题。
1.我国教师节(9月10日)期间,最接近的节气是( )A.立秋B.白露C.寒露D.小雪2.下面的时间段中,太阳直射点在北半球且向南移动的是( )A.春分→清明B.小暑→大暑C.霜降→立冬D.大雪→小寒解析:1.B 2.B [第1题,据图可知,相邻两个节气间隔大约为15天。
根据太阳直射点的移动规律可知,我国教师节(9月10日)大致位于9月23日(秋分)前半个月。
由此判断,最接近的节气为白露,故答案选B项。
第2题,据图及地球运动规律可知,春分→清明,太阳直射点由赤道向北移动,A错误;小暑→大暑,太阳直射点在北半球并向南移动,B正确;霜降→立冬,太阳直射点在南半球并向南移动,C错误;大雪→小寒,太阳直射点在南半球且先向南再向北移动,D错误,故答案选B项。
](2019·黑龙江伊春二中期中)表中所列的是12月22日前后甲、乙、丙、丁四地的白昼时间,根据表中数据回答3~5题。
A.甲地B.乙地C.丙地D.丁地4.四地所处纬度从高到低顺序排列的是( )A.甲、乙、丙、丁B.甲、乙、丁、丙C.丙、丁、乙、甲D.丁、丙、乙、甲5.造成四地白昼时间差异的主要因素是( )①地球的公转②地球的自转③黄赤交角的存在④地方时的不同A.①② B.②③C.③④ D.①③解析:3.D 4.B 5.D [第3题,北半球冬至日是12月22日前后,此时北半球昼短夜长,昼长小于12小时。
南半球昼长夜短,昼长大于12小时。
读表格,四地中昼长大于12小时的是丁地,属于南半球的是丁地,D对。
第4题,赤道昼长时间不变,始终是12小时。
其他地点纬度越高,昼长变化幅度越大,即与赤道昼长12小时的差值越大,纬度越高。
根据表格中昼长时间与12小时的差值判断,四地所处纬度从高到低排列顺序,即与赤道昼长差值由大到小的顺序,依次是甲、乙、丁、丙,B对。
