15．What you do each morning affects your entire day．The choices that we repeatedly make decide the life we live．（36）G
Manage your energy，not your time．
If you think about it，you'll probably realize that you are better at doing certain tasks at certain times．For example，my creative energy is highest in the morning，so that's when I do my writing each day．However，I spend my afternoons on phone calls，and emails，which don't need my creative energy to be high．（37）D What task is that energy best suited for？
Prepare the night before．
It is really necessary to spend a few minutes each night organizing your to-do list for tomorrow．When I do it，I'll outline the article I'm going to write the next day and develop a short list of the most important items for me to do．（38）F
（39）A
Sounds simple，yet nobody does it．It took me a while to get over the urge（渴望） to open my inbox，but finally I realized that everything can wait a few hours．Nobody is going to email you about a true emergency （a death in the family，etc．），so leave your email alone for the first few hours of each day．
Turn your phone off．
This reduces the urge to check text messages．This simple method reduces the possibility that you waste time on meaningless tasks．
You've got 25，000mornings．（40）B

A．Don't open email until noon．
B．What will you do with each one？
C．Leave your phone in another room．
D．What type of energy do you have in the morning？

18．Some 30，000 years ago，artists who lived in caves in Europe painted pictures of the animals around them：panthers，hyenas，rhinos，cave lions，mammoths and other creatures which have been extinct for a long time．
The artwork，more than a thousand drawings，is considered the oldest group of human cave drawings which have ever been discovered．They were preserved because the cave was sealed---closed off--for more or less 23，000 years．
Fast forward to December 18，1994，a group of French cave scientists were exploring caves in southern France．Jean Marie Chauvet，who led the group then，describes the process of discovering the cave paintings．"At that time I was in the front，Eliette just walked behind me，Christian behind．Eliette said she saw two marks with red ochre（赭石） and she said，‘They came here．'And at this very moment everything began．The drawings and everything linked to the parietal art（壁画）．That is where it started．"
Cave art expert Jean Clotttes reviewed the paintings．"I was amazed at the number of paintings there were and paintings of their quality and particularly in front of the panel of the horses．"
Scientific analysis confirmed the prehistoric date of the artwork．Studies showed the drawings were created tens of thousands of years ago，before human history was written．The United Nations'cultural agency UNESCO lists the cave as a World Heritage Site．They say that the drawings form a remarkable expression of early human artistic creation of grand excellence and variety．
The Chauvet Cave has been named after the explorer who first entered it．However，its environment and drawings are too fragile to be visited by human beings．So the cave is closed，and only people there for scientific purposes can go inside and see the artwork．
However，French authorities asked experts to create an exact copy of the cave，called Pont d'Arc Cavern．The copy，which we also called replica，cost more than 59 million dollars to build．It opened at the end of April in France．
Pascal Terrasse is the president of the cavern．He says everyone will be able to experience the thrill of looking at drawings made by the first humans in Europe．He says the place is magic because it is done so well．Authorities say they think as many as 400，000 people will be allowed to visit Pont d'Arc Cavern every year．
29．According to Jean Clottes'words in Paragraph 4，the paintings in the cave wereB．
A．abstract     
B．superior        
C．creative    
D．inspiring
30．Which of the follow statements is TRUE about the Chauvet Cave？C

B．It is thought to be the origin of modern parietal art．
C．The environment and artwork there are very easy to damage．
D．The majority of drawings there are about the extinct animals．
31．The purpose of creating Pndt d'Arc Cavern is toC．
A．show admiration for the earliest artists in Europe
B．arouse visitors'awareness of protecting ancient art
C．offer visitors chances to view the wonderful artwork
D．collect money for the perseverance of the Chauvet Cave．
5．Revealed to the world by the famous British explorer，Dr David Livingstone，in 1855，the Victoria Falls are one of Africa's best-known natural wonders．They form a natural border between Zimbabwe （津巴布韦） and Zambia （赞比亚）．
The falls are named after Queen Victoria by Livingstone．They were known to the native people in the 18th century as："the smoke that thunders"．The waterfall is formed as the two-kilometer-wide Zambezi River spills （溅） over the edge of its giant stone riverbed and falls into the gorge （山谷） below．At their highest point，the Victoria Falls drop a distance of 108m，almost twice as far as the Niagara Falls．As much as 546million cubic meters of water per minute falls over the edge from that height．
Viewing the falls from the Zambian side means that visitors can follow a path that goes right up to the falls．The falls can also be viewed from the Boiling Pot，right in the depths of the gorge at the bottom of the falls．The 111-meter-high Victoria Falls Bridge，a railway crossing，is now a popular place for Bungee jumping．It can be crossed on foot for excellent views of the falls and the winding blue-green waters of the Zambezi River．It is also possible to see the falls from a plane．
The area around the falls is a major game-viewing place．The best time to view the Victoria Falls is between December and July，when the water level is the highest．Contact Addresses Tourist Centre，Livingstone，Zambia Tel：（03）321 404E-mail：zntb@zamnet．zm Website：www．zambiatourism．com

16．Americans get some of their news and entertainment from public television and radio．These public media receive money to operate from private citizens，organizations and government．Many of their programs are educational．But most of the American media are run by businesses for profit．These privately owned media have changed greatly in recent years．Newspapers，magazines and traditional broadcast television organizations have lost some of their popularity．At the same time，online，cable and satellite media have increased in numbers and strength．So have media that serve racial groups and those communicating in foreign languages．
In general，more media than ever now provide Americans with news and entertainment．At the same time，fewer owners control them．Huge companies have many holdings（股份）．In some areas，one company controls much of the media．One dramatic change in American media is the increased success of cable television．It comes into most homes over wires．It does not use the public airwaves to present programs，as broadcast television does．Like broadcast television，most cable television programs perform advertisements．This is true although people must pay to see cable television in their homes．Thirty years ago，few people had cable．Today，about sixty-eight percent of American homes have cable television．Television by satellite also is gaining popularity．
Over the years，traditional broadcast organizations have tried to appeal to as many watchers as possible．Many cable companies，however，present programs for one special group of viewers．For example，there are cable stations for people who like books，cooking，travel，golf or comedy．
