We have designed all our bank cards to make your life easier.
Using your NatWest Service Card
As a Switch card, it lets you pay for all sorts of goods and services, whenever you see the Switch logo. The money comes straight out of your account, so you can spend as much as you like as long as you have enough money (or an agreed overdraft (透支) to cover it). It is also a cheque guarantee card for up to the amount shown on the card. And it gives you free access to your money from over 31,000 cash machines across the UK.

It can also give you access to your account and your cash from over 31,000 cash machines nationwide. You can spend or withdraw what you have in your account, or as much as your agreed overdraft limit.
Using your cards abroad
You can also use your Service Card and Cash Card when you?re abroad. You can withdraw cash at cash machines and pay for goods and services wherever you see the Cirrus or Maestro logo displayed.
We take a commission charge (手续费) of 2.25% of each cash withdrawal you make (up to£4) and a commission charge of 75 pence every time you use Maestro to pay for goods or services. We also apply a foreign-exchange transaction fee of 2.65%.

B
Once when I was facing a decision that involved high risk, I went to a friend. He looked at me for a moment, and then wrote a sentence containing the best advice I?ve ever had: Be bold and brave ? and mighty (强大的) forces will come to your aid.
Those words made me see clearly that when I had fallen short in the past, it was seldom because I had tried and failed. It was usually because I had let fear of failure stop me from trying at all. On the other hand, whenever I had plunged into deep water, forced by courage or circumstance, I had always been able to swim until I got my feet on the ground again.
Boldness means a decision to bite off more than you can eat. And there is nothing mysterious about the mighty forces. They are potential powers we possess: energy, skill, sound judgment, creative ideas ? even physical strength greater than most of us realize.
Admittedly, those mighty forces are spiritual ones. But they are more important than physical ones. A college classmate of mine, Tim, was an excellent football player, even though he weighed much less than the average player. ?In one game I suddenly found myself confronting a huge player, who had nothing but me between him and our goal line,? said Tim. ?I was so frightened that I closed my eyes and desperately threw myself at that guy like a bullet ? and stopped him cold.?
Boldness ? a willingness to extend yourself to the extreme?is not one that can be acquired overnight. But it can be taught to children and developed in adults. Confidence builds up. Surely, there will be setbacks (挫折) and disappointments in life; boldness in itself is no guarantee of success. But the person who tries to do something and fails is a lot better off than the person who tries to do nothing and succeeds.
So, always try to live a little bit beyond your abilities?and you?ll find your abilities are greater than you ever dreamed.
25. Why was the author sometimes unable to reach his goal in the past?
A. He faced huge risks. B. He lacked mighty forces.
C. Fear prevented him from trying. D. Failure blocked his way to success.
26. What is the implied meaning of the underlined part?
A. Swallow more than you can digest. B. Act slightly above your abilities.
C. Develop more mysterious powers. D. Learn to make creative decisions.
27. What can be learned from Paragraph 5?
A. Confidence grows more rapidly in adults. B. Trying without success is meaningless.
C. Repeated failure creates a better life. D. Boldness can be gained little by little.
C
The wallet is heading for extinction. As a day-to-day essential, it will die off with the generation who read print newspapers. The kind of shopping-where you hand over notes and count out change in return?now happens only in the most minor of our retail encounters,like buying a bar of chocolate or a pint of milk from a corner shop. At the shops where you spend any real money, that money is increasingly abstracted. And this is more and more true, the higher up the scale you go. At the most cutting-edge retail stores?Victoria Beckham on Dover Street, for instance?you don't go and stand at any kind of cash register when you decide to pay. The staff are equipped with iPads to take your payment while you relax on a sofa.
Which is nothing more or less than excellent service, if you have the money. But across society, the abstraction(抽象) of the idea of cash makes me uneasy. Maybe I'm just old-fashioned. But earning money isn't quick or easy for most of us. Isn't it a bit incredible that spending it should happen in half a blink(眨眼)of an eye? Doesn't a wallet?that time-honoured Friday-night feeling of pleasing, promising fatness?represent something that matters?
But I'll leave the economics to the experts. What bothers me about the death of the wallet is the change it represents in our physical environment. Everything about the look and feel of a wallet?the way the fastenings and materials wear and tear and loosen with age, the plastic and paper and gold and silver, and handwritten phone numbers and printed cinema tickets?is the very opposite of what our world is becoming. The opposite of a wallet is a smartphone or an iPad. The rounded edges, cool glass, smooth and unknowable as pebble(鹅卵石). Instead of digging through pieces of paper and peering into corners, we move our fingers left and right. No more counting out coins. Show your wallet, if you still have one. It may not be here much longer.
28. What is happening to the wallet?
A. It is disappearing. B. It is being fattened.
C. It is becoming costly. D. It is changing in style.
29. What makes the author feel uncomfortable nowadays?
A. Saving money is becoming a thing of the past.
B. The pleasing Friday-night feeling is fading.
C. Earning money is getting more difficult.
D. Spending money is so fast and easy.
30. Why does the author choose to write about what's happening to the wallet?
A. It represents a change in the modern world.
B. It has something to do with everybody's life.
C. It marks the end of a time-honoured tradition.
D. It is the concern of contemporary economists.
31. What can we infer from the passage about the author?
A. He is resistant to social changes.
B. He is against technological progress.
C. He feels reluctant to part with the traditional wallet.
D. He feels insecure in the ever-changing modern world.

干旱可促进植物体内脱落酸(ABA)的合成,取正常水分条件下生长的某种植物的野生型和ABA缺失突变幼苗,进行适度干旱处理,测定一定时间内茎叶和根的生长量,结果如图所示:
回答下列问题:
(1)综合分析上图可知,干旱条件下,ABA对野生型幼苗的作用是_______。
(2)若给干旱处理的突变体幼苗施加适量的ABA,推测植物叶片的蒸腾速率会______,以对环境的变化作出反应。
(3)ABA有“逆境激素”之称,其在植物体中的主要合成部位有______(答出两点即可)。

二、阅读下面文字,完成7?10题。(共16分。每小题4分)
阅读下面的文字,完成下面试题
树木都是比较长寿的,自然界中常有许多百年以上的大树,甚至也有上千年的古树。一般比较准确地确定古树的年龄,多用?数年轮?的办法。
什么是年轮呢?就是木本植物茎干横断面上的同心轮纹,在树木茎干的韧皮部内侧有一圈细胞生长特别活跃,分裂也极快,能够形成新的木材和韧皮组织,被称为形成层。可以说树干的增粗全靠它的力量,这些细胞的生长情况在不同的生长季节中有明显的差异。春天到夏天的天气是最适于树木生长的,因此形成层的细胞分裂较快,生长迅速。所产生的细胞体积大,细胞壁薄,纤维较少,输送水分的导管数目多,称为春材或早材;到了秋天,由于形成层的细胞的活动逐渐减弱,产生的细胞当然也不会很大,而且细胞壁厚,纤维较多,导管数目较少,叫做秋材或晚材;当年的早材与晚材逐渐过渡,组成一轮,而晚材与次年的早材之间,界限分明,出现轮纹,根据树干基部的年轮,可以推测树木的年轮。
但是也有一些植物,如柑橘,年轮就不符合这种规律,我们叫它?假年轮?,因为它们每一年能够有节奏地生长三次,形成三轮。此外,在热带地区的树木,由于气候季节性的变化不明显,形成层所产生的细胞也就没有什么差异了,年轮往往不明显。
古树年轮的研究,对近年开展的古气候讨论以及空气污染情况的研究都大有助益,首先树木的生长与气象的关系最为密切,从年轮宽,生长量大,推出那一时期风调雨顺,气温适宜;反之,年轮窄,则雨水稀少或干旱无雨,或气温过高或过低。美国科学工作者通过研究450株?世界爷?的年轮,发现它所记录的近百年气候变化,竞与现有文字记录相吻合;我国兰州大学在祁连山区采集900岁以上的圆柏树,发现其年轮宽窄变化与我国近1000年的气候变化相一致。此外,采用科学手段,可以从年轮里观察出空气污染的程度,美国有人对二氧化碳及氧化物散落较多的军工厂附近的43株美国五针松及50棵鹅掌楸进行年轮分析,发现这些树木的历年生长量与该厂排放的污染物质的多少有密切关系,污染物多,树木生长量就少。
第7题单选 下列对树木年轮的解释,最准确的一项是( )
A.树木年轮就是木本植物茎干横断面上的同心轮纹。
B.树木年轮是木本植物的主干由于季节变化生长快慢不同,在木质部的断面显出的环形纹理。
C.在树木茎干的韧皮部内侧有一圈细胞生长特别活跃,分裂也极快,能够形成新的木材和韧皮组织,它们就是树木年轮。
D.当年的早材与晚材逐渐过渡,组成一轮,而晚材与次年的早材之间,界限分明,出现轮纹。
参考答案:B
