在物理學(xué)中，磁場的強(qiáng)弱用磁感應(yīng)強(qiáng)度（用字母B表示，國際單位是特斯拉，符號(hào)是T）來表示，磁感線越密的地方，磁場越強(qiáng)，磁感應(yīng)強(qiáng)度B越大.

（1）在圖20中，甲為某磁極附近磁感線的方向和分布的示意圖，由圖可知，該磁極為 ▲ 極，若在l處放置一個(gè)小磁針，當(dāng)小磁針靜止時(shí)，其指向應(yīng)是圖乙中的  ▲   .
（2）磁敏電阻阻值的大小隨磁場的強(qiáng)弱變化而變，圖丁是某磁敏電阻R的阻值隨磁感應(yīng)強(qiáng)度B變化的圖象，據(jù)圖線可知，磁敏電阻的阻值隨磁感應(yīng)強(qiáng)度B的增大而▲ ．圖線沒有過坐標(biāo)原點(diǎn)，說明  ▲  .
（3）王強(qiáng)設(shè)計(jì)了一個(gè)可以測量該磁敏電阻R的電路如圖丙所示，（其中磁敏電阻所處的磁場未畫出）．將該磁敏電阻R放置在磁場中的位置某處，測出電阻后，利用R—B特性曲線可以讀出相應(yīng)的磁感應(yīng)強(qiáng)度.
①在圖甲磁場中1處，測得的數(shù)據(jù)如圖20表中所示，則該磁敏電阻的測量值為 ▲ Ω. 
②根據(jù)該磁敏電阻的R-B特性曲線可知，1處的磁感應(yīng)強(qiáng)度為   ▲    T.
③在實(shí)驗(yàn)過程中，僅將磁敏電阻從1處移至2處，其它條件不變，那么電流表的示數(shù)
▲   （填“增大”、“減小”或“不變”）.
④依據(jù)上述方法獲得的磁感應(yīng)強(qiáng)度B的測量值與該點(diǎn)實(shí)際值存在不小的誤差，為盡可能準(zhǔn)確反映空間某點(diǎn)磁場的強(qiáng)弱，你認(rèn)為在選擇磁敏電阻時(shí)應(yīng)注意什么問題？

書面表達(dá)

根據(jù)圖畫和所給單詞，將成語“鄭人買履”譯為英文小故事。詞數(shù)在60—80之間。

閱讀下列短文，根據(jù)其內(nèi)容完成后面各項(xiàng)任務(wù)。

These days, more and more young people wish to be more beautiful, so they turn to plastic surgery(整形手術(shù))for help. They spend thousands of yuan ①       these painful surgeries to fix their nose, to change their eyelids(眼皮) or to take off weight from their stomachs.

②In fact most people are not pleased with the way they look. Even ③最美麗actresses often wish they could change something about their looks. Should we live our whole lives believing we are ugly? Why can’t we raise our head high and believe that we are as beautiful as others? A smile is beautiful on my face, whether fat, oily or hairy. And a kind heart is much more beautiful than a pretty look. So, let’s feel grateful that we all have beautiful and healthy bodies that do not need surgeries! Today, I call on you to make an easy change: hold your head high, smile and be kind to others. If you do these, you will ④be full of confidence, beauty, and warmth everywhere you go.

It was a dark and cold night．The taxi driver didn’t have even one passenger all day．When he went by the railway station，①he saw a young man coming out with two bags in his hands．So he quickly opened the door of the car and asked，“Where do you want to go，sir?”
“To Star Hotel，”the young man answered．When the taxi driver heard this，he didn’t feel happy any more．He knew the young man could give him only three dollars because the hotel was not far from the railway station．But suddenly，he had   ②  idea．He took the passenger through many streets of the big city．
After a long time，the car arrived at the hotel at last．“You should pay me fifteen dollars，”the driver said to the young man．“What? Fifteen dollars! Do you think I’m a fool? Only last week, I took a taxi from the railway station to this same hotel and I only gave the driver thirteen dollars．I know how much I have to pay for the trip．I won’t pay you one dollar more than I paid to the other taxi driver last week．”
