What is cloning? Are there different types of cloning?

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.

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.

Over a year ago, my friend was ready to return after complete his tour in Singapore. He didn’t expect that he was about to get on his airplane when he stopped politely by one of the worker of the airport. He was told that he was not allowed to aboard. My friend had thought that there must be anything wrong with his ticket. The worker told him that was not his ticket but the book he hadn’t return to, which he had borrowed from a library, that caused the trouble. Certainly, my friend didn’t board but missed the flight. He wasn’t permitted to take the flight home a week late until he returned the book to the library.

下面文章中有5处（第66~70题）需要添加小标题。请从以下选项（A、B、C、D、E和F）中选出符合各段意思的小标题，并在答题卡上将相应选项的标号涂黑。选项中有一项是多余选项。
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. ______
Many gifted 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.

How to Become a Better Student
Maybe you are an average student. You probably think you will never be a top student. This is not necessary so, however. Anyone can become a better student if he or she wants to. Here’s how:
1. Plan your time carefully. When you plan your week, you should make a list of things that you have to do. After making this list, you should make a schedule of your time. First your time for eating, sleeping, dressing, etc. then decide a good, regular time for studying. Don’t forget to set aside enough time for entertainment. A weekly schedule may not solve all your problems, but it will force you to realize what is happening to your time.
2. Find a good place to study. Look around the house for a good study area. Keep this space, which may be a desk or simply a corner of your room, free of everything but study materials. No games, radios, or television! When you sit down to study, concentrate on the subject.
3. Make good use of your time in class. Take advantage of class time to listen to everything the teachers say. Really listening in class means less work later. Taking notes will help you remember what the teacher says.
4. Study regularly. When you get home from school, go over your notes. Review the important points that your teacher mentioned in class. If you know what your teacher is going to discuss the next day, read that material will become more meaningful, and you will remember it longer.
5. Develop a good attitude about tests. The purpose of a test is to show what you have learned about a subject. They help you remember your new knowledge. The world won’t end if you don’t pass a test, so don’t be overly worried.
There are other methods that might help you with your studying. You will probably discover many others after you have tried these.
