A.Means of ewaste recycling B.How ewaste comes into being C.The benefit of ewaste recycling D.The technologies of ewaste recycling E.The importance of the electronic waste recycle F.Modern technology brings convenience and ewaste |
Modern technology does bring us many conveniences(便利),from WiFi(无线网络)enabled cell phones and ever smaller laptop computers that make entire lives easy to energy efficient washers that use half the power and time to complete their tasks. However,these new toys and equipment finally become electronic waste ( 电子垃圾)(e waste)once they are out of use.
E waste includes everything from empty printer ink containers to broken refrigerators. As people buy new items to replace aging electronics or make upgrades(升级),more electronic waste comes into being. In some cases,such as 2009's switch from analog(模拟)to digital television broadcasting in the United States,changes in technology are so great that old equipment may not even work at all with new systems.
There are many reasons why it is important to recycle electronic waste. Much of the material used to construct electronics,including metal and plastic parts,can be recycled into new items at a discount of the cost and energy use needed to create things from new raw materials(原材料). Additionally,many electronics contain poisonous substances (有毒物质)that are harmful to the environment and could be deadly if they go into an area's groundwater. When properly recycled,they can be reused and will not do harm to the environment. Because of these environmental concerns,many areas require by law that electronic waste be properly recycled.
The availability(可用性)of ewaste recycling programs varies from place to place. In some areas,annual collections are held once or twice a year as a means of dealing with ewaste as well as used engine oil or other waste that is harmful to the environment. There are also some good alternatives (替代品) to recycling your ewaste. Any items that are in working condition can be given to friends or donated to charities(慈善机构)like Goodwill or the Salvation Army,who rely heavily on donations ( 捐赠) . Freecycling ,or passing on your unwanted items to those in need of them,is also a means of finding new homes for used items.
Ewaste recycling helps protect the environment by reducing the amount of poisonous materials placed in landfills(垃圾场)and saving recyclable parts to save energy and other resources. Recycling is a way of life. Stick to that choice every single day and recycling will become second nature to us.
What is cloning? Are there different types of cloning?
_____71____ Actually, there are different technologies which can be used for other purpose besides producing the genetic twin of another organism. A basic understanding of the different types of cloning is key to talking an informed stance on current public policy issues and making the best possible personal decisions. The following three types of cloning technologies are usually performed; recombinant DNA technology or DNA cloning, reproductive cloning, and therapeutic cloning.
___72_____
Scientists have been cloning animals for many years. In 1952, the first animal, a tadpole, was cloned. ___73_____ Since Dolly, researchers have cloned a number of large and small animals including sheep, goats, cows, mice, pigs, cats, rabbits, and a gaur. ____74____
Hundreds of cloned animals exist today, but the number of different species is limited. ____75____ Some species may be more resistant to somatic cell nuclear transfer than others. The process of stripping the nucleus from an egg cell and replacing it with the nucleus of a donor cell is a traumatic one, and improvements in cloning technologies may be needed before many species can be cloned successfully.
A.What animals have been cloned? |
B.All these clones were created using nuclear transfer technology |
C.When the media report on cloning in the news, they are usually talking about only one type called reproductive cloning. |
D.Recently Chinese scientists have also successfully cloned mammals such as an ox. |
E.Cloning is making a genetic copy of something else.
F.Attempts at cloning certain species such as monkeys, chickens, horses, and dogs, have been unsuccessful.
G.Before the creation of Dolly, the first mammal cloned from the cell of an adult animal, clones were created from embryonic cells.
Most drinks stating that they are fruit flavored (水果味道的) contain no fruit at all, while most of the rest contain only a small quantity of fruit, according to a study carried by the British Food Commission.
“Shoppers need to check the labels (标签) before buying drinks, though sometimes the actual content can be nonexistent,” said Food Commission spokesperson Ian Tokelove. “Food production is highly competitive. __1__ It will increase profits, and consumers won't always realize they are being tricked.”
Flavorings are focused on the flavors of natural food products such as fruits, meats and vegetables, or creating flavor for food products that do not have the desired flavors. Researchers analyzed the contents of 28 strawberry flavored products sold in stores. __2__ Of the 11 products that did contain strawberries, five of them contained less than one percent real fruit. In addition, each juice box contained nearly eight teaspoons of sugar.
__3__Let's take jam as an example. Some strawberry flavored jam was labeled as containing no artificial colors, flavors, or sweeteners, but it contained absolutely no strawberries at all.
__4__Consumers have the rights to know clearly about what they have bought. Under current UK law, food packages do not have to distinguish between natural and artificial flavoring. “Describing a product as strawberry flavor and covering the surface of the packet with pictures of strawberries is misleading. __5__ Unfortunately, it is also legal and widespread,” Tokelove said. “It's time to take measures to protect the consumers' rights.”
A.The products which contain real fruit are popular with people. |
B.Even products advertised as more natural often contained no fruit. |
C.They found that about 60 percent of them didn't contain any fruit at all. |
D.If companies can cut their costs by using flavoring, they are likely to do so. |
E. It is important and necessary to demand a small amount of flavoring in the products.
F. Actually the product contains just a tiny percentage of strawberry or even no fruit at all.
G. The Food Commission suggested all flavors used in a product should be listed on the packaging.

1. So when you want to do business in France, you have to get to know French culture, to make marketing plans, and to run your business by local laws.
2The French take great pride in their language, so anyone who does not speak it may run the risk of being disrespected by his French colleagues or business partners. Also, another reason why learning French is important is that it is a great way to show every possible French business partner that you care and respect their country’s culture and language.
The first thing that you should do when meeting someone new is to shake his hand firmly and always look the person in the eye. In social meetings with friends, kissing is common.
Use first names only after being invited to. 3The French will sometimes introduce themselves using their surname first, followed by their first name.
Dress well. The French draw information about people based on their appearance. Your business clothing is a sign of your success and social status. Always try to be tasteful and stylish. Women are advised to dress simply but elegantly. Wearing make-up is practised widely by business women.
The French are passionate about food, so lunches are common in doing business in France, which usually consist of an appetizer, main meal with wine, cheese, dessert and coffee, and normally take up to two hours. 4
Do not begin eating until the host says, “bon appetite”. Pass dishes to the left, keep hands above the table and try to eat everything on the plate. 5This may suggest that you find the food tasteless. If eating in a restaurant, the person who invites always pays.
A.Maybe you have heard the expression “When in Rome, do as the Romans do” |
B.This is a time for relationship building. |
C.Remember to be as polite as possible. |
D.Language should be the focus of anyone planning to do business in France. |

A. Read on B. Read loudly C. Select a proper material D. Think while you are reading E. Use a dictionary at a right time F. Five suggestions for achieving better results. |
Effective reading should adopt a correct way, and then you can get more by paying less. Here are some suggestions for reading effectively.
1.
Don’t choose a rather difficult book or a too easy one for yourself to read. A book full of new words will make you discouraged quickly. To understand these new words, you have to turn to the dictionary quite often. It seems that you are not reading the book but the dictionary. It has no fun at all! On the contrary, a too easy one will only waste your time and cannot do any help. The two extremes may at last make you give up reading. So it’s better for you to find a proper book with no more than five new words on each page.
2.
If you come across a new word, do not look it up in a dictionary as quickly as possible. Leave it alone and guess the meaning of it based on the content of the text. This ability is quite necessary in reading. If you know your guess is right later, you will be highly excited at your “success”, and your interest in reading is well stimulated. If a word really hinders you from understanding the whole passage, turn to the dictionary by then. I am sure you can remember this word very well, as it has left you such a deep impression for “its troublesome image”.
3.
To comprehend what you are reading, you should think while you are reading, then form your own ideas on some special issues. Try to scribble (乱写;潦草地书写)some lines — a very short journal, to express your ideas. Your writing does not need to be quite formal but expressive. This practice can make you communicate with the original English authors. Day by day, your way of thinking in English will turn into a native way, which is quite important for English writing.
4.
Language has its own beauty, no matter Chinese or English. Don’t merely take English as a “test”. Take it as an “entertainment” instead and you will enjoy it through learning. Maybe you should find some beautiful literary works such as a prose or a poem to read, if you like. Try to read them as loudly and passionately as you can. During this process, not only can you enjoy yourself by the great emotions of the writers, but also your pronunciation and your manner of speaking English will be improved.
5.
The last but not the least, keep on reading. If you cannot keep it as a habit, you will suffer from paying without gaining.
