Nowadays, people are very busy. Often, both parents work outside the home. Children are expected to take on more responsibility at home to help their parents. They also have sporting and leisure activities as well as school expectations.
The busyness also adds another factor: the need to use cars to get from one place to another quickly.
Today, society places a lot of emphasis on technology. Computers, DVDs, CDs, television, PlayStations and Xboxes have become major leisure activities, rather than traditional more active pursuits. This has led to a more sedentary lifestyle.
The media provide entertainment and information. (79)Unfortunately, they also promote fast food which fits easily into busy lifestyles. It is much more convenient at times to buy a quick takeaway rather than prepare a meal. The media constantly bombard(轰炸) their audience with "perfect" body images, the need to buy the most fashionable clothes, the most up-to-date computer games, the best places to visit and the best things to do.
Environments vary. We may be exposed to pollution, such as cigarette smoke. This can be harmful to people who suffer from breathing difficulties. (80)Environments where passive smoking is unavoidable make it difficult to lead a healthy life.
Perhaps the important factor influencing healthy lifestyles is motivation, or the desire to be healthy. Any person who wants to be healthy will find a way to be healthy—if he/she is motivated enough!
The passage is mainly about______.
A．benefits of a healthy life style
B．demands of daily life
C．factors affecting a healthy lifestyle
D．a positive approach to healthy living
Business ethics is not about personality, though a good personality is valuable. Ethics is the primary element and prerequisite for successful business. No matter what you do, you should think of business as a matter of integrity. Nowadays, the slip in ethics and the absence of social responsibility, especially integrity, have led to a crisis in business, seriously influencing social development.
Events resulting from a loss of trust are being seen now and then and they affect the society in many unfortunate ways. Most people know the importance of business ethics, but still some people don't honor them. We often hear media reports on problems in business, such as adding harmful materials to products. These behaviors cause much damage to consumers, who spend money but do not get quality commodities, especially when these commodities do great harm to their health. It is difficult for people to forget the case in which some children consumed unsafe milk powder produced by a few immoral businesses, and their health suffered serious damage as a result. People can't bear this kind of behavior. and the businesses responsible must be closed down and the related personal be published.
1.What is the primary component for a prosperous business？
A.Good management
B.Business ethics
C.Reliable credit status
2.What is the influence of losing integrity？
A.Hinder social development
B.Worsen the company's reputation
C.Reduce people's trust between each other
3.What is people's attitude towards business ethics？
A.All people pay attention to business ethics
B.Most people attach importance to it and follow it
C.Lots of people know its importance but still some don't honor it
4.Which of the following items is NOT mentioned in this passage？
A.The absence of ethics has led to a crisis in business world
B.Manufacturers' immoral behaviors do little harm to consumers
C.Media is important for people to know more about commodities
5.What is the author's attitude toward immoral behaviors in business？
A.Critical
B.Affirmative
C.Indifferent
Radiocarbon Dating
Nowadays scientists can answer many questions about the past through a technique called radiocarbon(放射性碳), or carbon-14, dating. One key to understanding how and why something happened is to discover when it happened.
Radiocarbon dating was developed in the late 1940s by physicist Willard F. Libby at the University of Chicago. An atom of ordinary carbon, called carbon-12, has six protons(质子) and six neutrons(中子) in its nucleus. Carbon-14, or C-14, is a radioactive, unstable form. of carbon that has two extra neutrons(原子核). It returns to a more stable form. of carbon through a process called decay(衰减). This process involves the loss of the extra neutrons and energy from the nucleus.
In Libby's radiocarbon dating technique, the weak radioactive emissions(放射) from this decay process are counted by instruments such as a radiation detector and counter. The decay rate is used to determine the proportion of C-14 atoms in the sample being dated.
Carbon-14 is produced in the Earth's atmosphere when nitrogen(氮)-14, or N-14, interacts with cosmic rays(宇宙射线). Scientists believe since the Earth was formed, the amount of nitrogen in the atmosphere has remained constant. Consequently, C-14 formation is thought to occur at a constant rate. Now ratio of C-14 to other carbon atoms in the atmosphere is known. Most scientists agree that this ratio is useful for dating items back to at least 50,000 years.
All life on Earth is made of organic molecules(分子) that contain carbon atoms coming from the atmosphere. So all living things have about the same ratio of C-14 atoms to other carbon atoms in their tissues(组织). Once an organism(有机体) dies it stops taking in carbon in any form, and the C-14 already present begins to decay. Over time the amount of C-14 in the material decreases, and the ratio of C-14 to other carbon atoms goes down. In terms of radiocarbon dating, the fewer C-14 atoms in a sample, the older that sample is.
Nowadays many scientists depend on radiocarbon for dating age-old objects.
A．Right
B．Wrong
C．Not mentioned
I【69】about it with my friends Frank and Lesley.【70】of them【71】suggest anything, but they promised that they would ask their friends. A few days later【72】I was still in bed,【73】telephoned.

"He seemed pleasant on the phone【75】I went to see him. I was so excited that I almost forgot【76】goodbye. "Good luck!" my mother said to me.
I arrived【77】early and when Mr. Thomson came he asked me if I【78】waiting a long time. "No, not long." I replied. After talking to me for about twenty minutes he【79】me a job-- not as a photographer though,【80】a model!
