On warm summer days with little or no wind, the air temperature in cities can be up to ten degrees higher than that of the surrounding countryside. This is a phenomenon commonly referred to as the “urban heat island” effect.

This phenomenon happens when pavement, buildings, and other infrastructure (基础设施) replace natural land cover. Large amounts of paved and dark colored surfaces—such as roofs, roads, and parking lots—absorb, rather than reflect, the sun’s heat, causing surface temperatures and overall ambient (周围的) air temperature to rise. Unlike soil, paved areas contribute to runoff, which means that as paved areas increase, the amount of water available for evaporation (蒸发) decreases. Moreover, urban areas have fewer trees and less natural vegetation which help to control the heat by providing shade and blocking solar radiation. The surfaces of leaves also provide water for evaporation which cools the air, further worsening the heat island effect.

In particular, during summer, more energy is required to cool the insides of building and for refrigeration, thereby creating additional heat output. This in turn leads to higher ambient air temperatures, which can also significantly increase the formation of urban smog in an area, degrading local air quality. Such a situation may directly affect public health with individuals more likely to suffer from heat exhaustion and the effects of asthma (哮喘).

1.The underlined part in Paragraph 2 means ________.

A.Due to dark colored roads, urban areas are becoming hotter each year

B.Dark colored surfaces reflect the sun’s heat, causing air temperatures to rise

C.Because urban surfaces absorb heat, air and surface temperatures increase

D.Rising ambient air temperatures lead to urban surfaces absorbing more heat

2.Which of the following is not a cause of the urban heat island effect?

A.The lack of trees

B.The demand for refrigeration

C.The blocking of solar radiation

D.The construction of infrastructure.

3.The underlined word “degrading” most probably means ________.

A.ignoring B.improving

C.highlighting D.worsening

4.The passage is mainly developed by ________.

A.giving typical examples

B.following the time order

C.presenting the effect and analyzing the cause

D.analyzing a problem and seeking the solution

You can set a budget for your time just as you can set a budget for your money. Since you’re trying to reduce worry rather than increase it,go into this process with a focus on maximizing(使…最大化)your personal time,rather than cramming(塞满) as much as you can into each day.

● Set a sleep schedule 1. Give yourself a one-hour target window for bedtime in the evening,and set a strict time to get up in the morning.Be sure that the space between your bedtime and the start of your day gives you roughly an hour more than the amount of sleep you actually need.2.

●Take care of tasks at the same time every day. Plan time for daily health care, commuting(乘公交下上班),work,shopping,eating,and chores(家务).Add in time for anything else you do most days,such as homework,exercise,or an active hobby. 3.All the time left over is your free time,to use for relaxation or whatever else you want.

● 4. For example,you might plan to go, dropping on your way home from work, to save the extra trip

For many people,an irregular work schedule make this kind of budgeting difficult.5.

A. However, you can still plan to work around your schedule in the same order every day.

B.Stick to it,even on weekends

C.Try to combine trips outside the home to maximize your free time

D.Different days call for different approaches.

E.Therefore.you won’t lay down and start worrying about whether or not you’ll fall asleep on time.

F.Sit comfortably and focus on your breathing until the rest of your thoughts become quiet.

G.Put them in a specific order that works for you

“A very destructive seven-year old child kicked my legs and scratched at my hand,” said one teacher. “I broke up a fight and was kicked,” said another. Many people have heard stories like this. But the situation is more worrying still and it involves parents.

Every child, regardless of the circumstances into which they are born, has the right to achieve their potential, regardless of their parents' wealth and class. And we recognize that, as a nation, it is a long way to achieve this goal. But rights come with responsibilities and what worries people is that we are in danger of neglecting the latter.

Far too many children are behaving badly at school, even to the point of being violent to staff. This is terrible enough, but it is hard to be surprised since many children are just mirroring the behavior of their parents. Too many are starting school unable to hold a knife and fork, unused to eating at a table,and unable to use the lavatory properly.

We are in danger of becoming a nation of families living separate lives under one roof. The bedroom, once a place to sleep, has become the living space for the young. Spending hours in front of computer screens, on social networking sites or being immersed in computer games, children and young people spend little time with their parents. Parents are unable to monitor just what their children are watching.

Schools cannot right the wrongs of society and teachers cannot become substitute parents. Both parties need to work together. Parents must be helped and given confidence to take back control. They are responsible for setting boundaries for their children's behavior and sticking to those boundaries when the going gets tough. They are responsible for setting a good example to their children and for devoting that most precious of resources---time---so that children come to school ready and willing to learn.

1.What problem do people ignore in the writer's opinion?

A. The school violence.

B. The pressure of students' learning.

C. The right to achieve students' potential.

D. Students' responsibilities.

2.The writer's attitude to the behaviors of parents may be that of____________.

A. dissatisfaction B. sympathy

C. understanding D. tolerance

A. children don't live with their parents in the same room

B. parents care little about children's life at home

C. children spend little time with their parents at home

D. parents attempt to establish a good relationship with their children

4.From the last paragraph, we can infer that__________.

A. Schools can’t correct the wrongs that society does to teachers

B. Teachers have no responsibility for playing the role of parents

C. Parents should spend time with children making them ready to learn

D. Students are responsible for making themselves known in society

5.What is the main idea of the passage?

A. Children’s behavior at school is worrying people

B. Parents expect schools to correct their children’s bad habits

C. There is no point in parents’ teaching children at home

D. Don’t blame teachers when it’s parents who are failing

Human beings have used tools for a very long time. In some parts of the world you can still find tools that people used more than two million years ago. They made these tools by hitting one stone against another. In this way, they broke off pieces from one of the stones. These chips of stone were usually sharp on one side. People used them for cutting meat and skin from dead animals, and also for making other tools out of wood. Human beings needed to use tools because they did not have sharp teeth like other meat eating animals, such as lions and tigers. Tools helped people to get food more easily.

Working with tools also helped to develop human intelligence. The human brain grew bigger, and human beings began to invent more and more tools and machines. The stone chip was one of the first tools that people used, and perhaps it is the most important. Some scientists say that it was the key to success of mankind.

Since 1960 a new kind of tool has appeared. This is the silicon chip (硅芯片). It is smaller than a finger nail, but it can store lots of information. It is an electronic brain. Every year these chips get cleverer, but their size gets smaller, and their cost gets less. They are used in watches, calculators and intelligent machines that we can use in many ways. In the future we will not need to work with tools in the old way. Machines will do everything for us. People will have plenty of spare time. But what will they do with it?

Human beings used stone chips for more than two million years, but human life changed very little in that time. We have used silicon chips for only a few years, but life is changing faster every day. What will life be like twenty years from now? What will the world be like two million years from now?

1.From paragraph 1, we can know ________.

A. why early human beings cut skin from dead animals

B. how early human beings discovered the tools

2.The stone chip is thought to be the most important tool because it ________.

A. was very important to the development of mankind

B. led to the invention of machines in the early time

C. developed cooking abilities of mankind

D. was one of the first tools of mankind

3.The silicon chip is mentioned in the passage to ________.

A. show the changes of tools

B. introduce a new kind of tool

C. give an example of using tools

D. compare the effects of two kinds of tools

4.At the end of the passage the author seems to suggest that life in future is ________.
