/ -est
双音节形容词以-y或-ly结尾去掉y, 再加-ier / -iest happy→happier, the happiest 以非重读元音、/ l /或

多音节形容词含三个或三个以上音节more / most+形容词原

二、形容词比较级的用法
1. 形容词的比较级常用来比较两种人或事物, 常见的结构为“形容词比较级+than”。
如: This book is more difficult than that one.
2. 两个相同形容词的比较级用and连接, 称为双重比较级, 意为“越来越……”, 用来说明某个事物正处于变化之中。
如: Our city is becoming more and more beautiful.
3. 常与形容词比较级连用表示比较的程度的副词有: much, far, a lot, a little, a bit等。如:
This film is far more interesting than that one.
4. “the+比较级……, the+比较级……”意为“越……就越……”。
The more you practise, the better you will speak English.
提示: 比较中应注意的问题:
1.只有同类事物才能进行比较。

2. 被比较的事物中不可以包括本身。

Tom is taller than any of the other students in his class.

三、形容词最高级的用法

Jack is taller than me. I am taller than Peter.
Jack is the tallest among three of us.
Lesson 4 is the most important of all the lessons.
2. 常用“one of + the + 形容词最高级+可数名词复数形式+比较范围”来表示“是……之中最……的之一”。如:
Guangzhou is one of the most beautiful cities in China.
提示:
当形容词最高级作前置定语修饰名词时, 在不影响句意理解的前提下, 可省略该名词,
避免意思重复。

The teacher brought us up to the front of the classroom and placed him on one side of her desk and me on the other. In the middle of her desk was a large and round object. I could clearly see that it was black. She asked the boy
what colour the object was. "White," he answered.
I couldn't believe (相信) he said the object was white, when it was obviously (明显地) black! The argument about the colour of the object started between my classmate and me.

had to answer, "White."

from my side was it black.

Tokyo is one of the most confusing cities in the world. Over 20 million people live and work in the Tokyo area, and many world-famous companies have their offices there. But most streets don't have names. So how can you find your way in Tokyo?
Most people in Tokyo are very good at giving directions. They can usually explain(说明) how to get to their home or their office from the nearest train station. People in Tokyo often use maps when they give directions.
Advertisements in newspapers or magazines, for example, usually have a small map to help you find the company. If you are going to visit someone's house, it's a good idea to ask the person to draw a map of the local area. If you get lost, the best idea is to go to a police station. In Japan,
each neighborhood has a small police station, and the police officers there have a map of all the buildings in the area. Giving directions is an important part of their job.

To have a healthy vision, it's a good idea to set rules for your children when it comes to the amount of time they spend in front of the computer.
1. Have your child's vision checked. Before starting school, every child should have an eye exam, including near-point (computer and reading) and distance testing.
2. Control the amount of time. Your child may spend all his or her spare time on the computer without a break. Encourage kids to take 20-second breaks from the computer every 20 minutes to reduce (减少) the development of eye focusing problems. (Some eye doctors call this the "20-20 rule".)
3. Check the workstation. For young and small children, make sure the computer workstation is adjusted(调整) to their body size. The right distance between the monitor and the eye for children is 18 to 28 inches. Viewing the computer screen closer than 18 inches can make the eyes
nervous.
4. Check the lighting. To reduce glare (刺眼的光), windows and other light sources should not be directly visible when sitting in front of the monitor. Reduce the amount of lighting in the room to match the computer screen.
( ) 46. What does the underlined word "vision" mean?
A. The ability to think.
B. The ability to see.
C. The ability to dream.
D. The ability to hear.
( ) 47. What is the 20-20 rule?
A. Take 20-second breaks every 20 seconds.
B. Take 20-second breaks every 2 minutes.
C. Take 20-minute breaks every 20 minutes.
D. Take 20-second breaks every 20 minutes.
( ) 48. Which of the following is NOT right about the distance between the eye and the monitor?
A. 17 inches.
B. 27 inches.
C. 19 inches.
D. 21 inches.
( ) 49. What is the advice before starting school?
A. Checking the lighting.
B. Checking the workstation.
C. Checking the child's vision.
D. Controlling the amount of time.
( ) 50. Who might the passage be written for?

Most parents love the Internet and want their kids to use it. But a new survey (调查) in America finds many parents are also afraid of the online world. They worry that their kids will get in trouble with people they meet online.
The study was done online from May 5 to May 10 by Insight Research Group. It says 80% of parents are worried about kids meeting bad people online. That's because young people who largely have grown up with the Net think of it as a way of showing personal feelings. To young people, the benefits (好处) of giving out some personal information to online friends outweigh (超过) the risks (风险). And, the study shows they are so comfortable with the Internet that 78% of them have a personal website or blog.
Parents also realize the importance of the Internet. The survey shows 91% think the Net helps their children show their feelings, and 77% think the Internet is one of the most valuable education tools that children have. But 88% think it's important to know what their kids are doing online. Findings show both parents and children need more education about using the Internet.
( ) 51. Who is afraid of the online world?
A. Students.
B. Parents.
C. Teachers.
D. Scientists.
( ) 52. Why may young people get in trouble with people they meet online?
A. Because they feel it's good to get on the Internet.
B. Because they look on those people as their real friends.
C. Because they like to make friends with people online.
D. Because they may give out their personal information online.
( ) 53. What is the third paragraph about?
A. The importance of the Internet.

第三方支付安全性及风险防范 一、第三方支付概念 第三方支付是阿里巴巴集团主席马云在2005年瑞士达沃斯世界经济论坛上首先提出来的，目前为止学术界还没有给出一个非常明确的概念。第三方支付是非金融机构从事金融业务的重要渠道，人民银行发布的《非金融机构支付服务管理办法》中将其定义为依托公共网络或专用网络，在收付款人之间作为中介机构，提供网络支付、预付卡的发行与受理、银行卡收单以及中国人民银行规定的其他支付服务的非金融机构。 从其形式上看，所谓第三方支付，就是具备一定实力和信誉的第三方独立机构提供的网络支付平台，它是以非银行机构的第三方支付公司为信用中介，以互联网为基础，通过与各家银行签约，使得其与商业银行间可以进行某种形式的数据交换和相关信息确认，实现持卡人或消费者与各个银行以及最终的收款人或者商家之间建立一个支付的流程。第三方支付通过其支付平台在消费者、商家和银行之间建立连接，起到信用担保和技术保障的作用，实现从消费者到商家以及金融机构之间的货币支付、现金流转、资金结算等功能。在网络交易中，买方选购商品后，使用第三方支付平台把货款支付给第三方，再由第三方通知卖家货款到达并要求卖家发货，买方收到商品并检验后通知第三方，由第三方将货款转至卖家账户。相对于传统的资金划拨交易方式，第三方支付可以对交易双方进行约束和监督，有效地保障货物质量、交易诚信、退换要求等环节，满足电子商务交易的安全性，为交易成功提供必要的支持。如支付宝、财付通等都属于此类平台。 与其他支付方式相比，第三方支付服务具有以下特征： （1）支付中介。第三方支付的具体形式是付款人和收款人不直接发生货款往来，借助第三方支付平台完成款项在付款人、银行、支付服务商、收款人之间的转移。第三方支付平台所完成的资金转账都与交易订单密切相关。 （2）中立、公正。第三方支付平台不直接参与商品或服务的买卖。公平、公正地维护参与各方的合法权益。
