The oldest stone buildings in the world are the pyramids. __66__. There are over eighty of them scattered along the banks of the Nile, some of which are different in shape from the true pyramids. The most famous of these are the “step” pyramid and “ Bent ”pyramid.
Some of the pyramids still look much the same as they must have done when they were built thousands of years ago. Most of the damage suffered by the others has been at the hands of men who were looking for treasure or, more often, for stone to use in modern buildings.__67__. These are good reasons why they can still be seen today, but perhaps the most important is that they were planned to last forever. __68__. However, there are no writings or pictures to show us how the Egyptians planned or built the pyramids themselves. __69__. Nevertheless, by examining the actual pyramids and various tools which have been found, archaeologists have formed a fairly clear picture of them.
One thing is certain: there must have been months of careful planning before they could begin to build. __70__. You may think this would have been easy with miles and miles of empty desert around, but a pyramid could not be built just anywhere. Certain rules had to be followed, and certain problems had to be overcome.

A．The dry climate of Egypt has helped to preserve the pyramids, and their very shape have made them less likely to fall into ruin.

B．It is practically certain that plans were made for the building of the
pyramids because the plans of other large works have fortunately been preserved.

C．The first thing they had to do was to choose a suitable place.

D．Consequently, we are only able to guess at the methods used.

E. Many people were killed while building the pyramids.
F. They have stood for nearly 5,000 years, and it seems likely that they will
continue to stand for thousands of years yet.
G. It takes workers twenty years to build the Pyramids.

A. Explore All Your Talents
B. Be Ready for the Up-coming Competition
C. Set a Down-to-Earth Goal
D. Prepare Yourself Emotionally
E. Look for a Competitive College
F. Consider Talent Search Programs in Junior High
Many aspects of college planning are the same for most college-bound students. However, if you’re in any academically gifted and talented program, you have additional things to think about. Here are some actions you should consider.
66.______
Talent search programs provide educational opportunities for seventh-and eighth-graders who are mathematically or verbally talented. Some of these programs use SAT scores to identify academically gifted students. Although most students take the SAT in junior or senior year of high school, gifted and talented student often take it earlier.
67. ______
Many gifted students have the potential to succeed in multiple academic areas. Don't miss opportunities by focusing too early on one that you excel in; carefully examine all your strengths and interests. Discover what you really like to study and the topics you may want to pursue in college. Pursue your interest and passion for learning to the fullest extent possible while you’re still in high school.
68. ______
Gifted students often feel that they have to be accepted by very competitive colleges to be considered successful. And while a competitive college may be the right place for you, don’t let selectivity be the only factor. The most important aspect of college planning is finding a college that’s a good fit.
69. ______
Manygifted students are used to being at the top of their junior high and high school classes. Be prepared to meet other gifted students in college — students who do just as well as you, or better, in the classroom. It can be unsettling. Handle it by staying focused on your own studies and skills and aiming to do your personal best.
70. ______
Although your academic qualifications and abilities may exceed those of your high school classmates, your age is the same as theirs. High school is a time for adolescence, while college requires emotional maturity. A 15-year-old high school graduate may not be prepared to live on a campus 1,000 miles from home with other students who are 18 and older. Think about what you are ready for emotionally, as well as academically, when you’re narrowing down your college list.

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.

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.

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.
