More and more students are doing part-time jobs today. There are many advantage in students doing part-time jobs. Except earning some money to support themselves, they can learn stuff what cannot be learned from textbooks. We will learn to get along with different kinds of people, get useful working experience and to learn the value of labor.
Therefore, there are also some disadvantages. For example, too much work may take up much of the students’ study time and affected their studies. Another disadvantage is that money earned, if not proper used, may lead to some bad habits, or even greed.

Wild elephants that destroy crops and damage trees 1.(be) a serious problem in many parts of Africa. But there could be a simple and 2.(relative) safe way to stop them in their tracks, by 3.(employ) the talents of the tiny African honeybees.
The number of elephants in Kenya 4.(rise) over the past ten years, with some disastrous results. Not only do these huge animals attack local farms 5. they step someone to death an average of once every two weeks. Now a biologist has discovered a possible threat: the elephants are extremely aware 6. trees that house honeybee hives.
''I am 7.(puzzle) why nobody has thought of this before, ''says Fritz Vollrath at the University of Oxford. ''When an elephant knocks a beehive he runs and the bees will follow him for miles. '' He says that placing hives of the honeybees around local farms could be 8. effective way to threaten the animals. Vollrath put 30 unoccupied and 6 occupied 9.(beehive) in some of the trees growing on a bush frequently damaged by elephants. On average the elephants attacked 9 out of 10 trees that didn’t have hives. But 10.(them) avoided all six trees with occupied hives.

What were you like as a teenager? I was a _______. I was rude to my parents, always stayed out late, never did my homework, hung out with the wrong people and made many _______ decisions. Apparently, this is the age when teenagers are out of control and _______ badly. If you're a teenager now, you think this is _______ criticism or it's not your fault. Well, you might be _______!
Experts have found that it's a teenager's brain that is to _______. Between the ages of _______ 13 to 19 the brain is still developing in areas that _______ behaviour. This has an/a _______ on learning and multitasking, stress and memory, sleep, addiction, and decision-making. This is quite a new ________, according to Professor Sarah, ''when I was at university, the dogma (教条) in the text books was that the vast brain ________ goes on in the first few years of life and nothing much ________ after mid-childhood. That dogma is completely ________.''
So our brains are still developing much later than was originally thought. Is this the perfect excuse for teenagers to ________ and not get their homework done on time?

So getting organized to do their homework, for example, can be a bit ________.
I wish I'd known about this because instead of telling my ________ I'd left my homework on the bus or that the dog had ________ it. Now I could say, ''Sorry sir, my ________ isn't developed enough for the cognitive task of planning my homework''.

People express their personalities in their clothes, their cars, and their homes. Because we might choose certain foods to ''tell'' people something about us, our diets can also be an expression of our personalities. For example, some people eat mainly gourmet foods, such as caviar (鱼子酱) and lobster (龙虾), and they eat only in expensive restaurants. 1.
Human beings can eat many different kinds of foods, but some people choose not to eat meat. 2.Their personalities might be similar too. For example, vegetarians in the United States and Canada may be creative people, and they might not enjoy competitive sports or jobs. They worry about the health of the world, and they are probably strongly opposed to war.
3. One study shows that many fast food eaters have a lot in common with one another, but they are very different from vegetarians. They are competitive and good at business. 4. Many fast food eaters might not agree with this description of their personalities, but it is common picture of them.
Some people also believe that people of the same astrological sign (星座) have similar food personalities. Aries (born under the sign of Aries, between March 21 and April 20) usually like spicy foods, with a lot of onions and pepper. People with the sign of Taurus (April 21 to May 22) prefer healthful fruits and vegetables, but they often eat too much. 5. Aquarius (January 21 to February 19) can eat as much meat and fish as they want, but sugar and cholesterol (胆固醇) are sometimes problems for them.
A.They are also usually in a hurry.
B.Some people eat mostly fast food.
C.They know about the “better things in life”.
D.Vegetarians often have more in common than just their diet.
E.People's personalities have something to do with their parents.
F.Many people avoid alcohol, which makes the body lose too much water.
G.Sagittarius (November 22 to December 22) like ethnic foods from many different countries.
Since the Second World War, there has been an obvious trend, especially among the growing group of college students, toward early marriage. Many youths begin dating in the first stages of adolescence, ''go steady'' through high school, and marry before their formal education has been completed. In some quarters, there is much shaking of graying heads over the ways of rebellious youth. However, emotional maturity does not grow with age; it does not arrive automatically at twenty-one or twenty-five. Some achieve it surprisingly early, while others never do, even in three-score years and ten.
Many students are marrying as an escape, not only from an unsatisfying home life, but also from their own personal problems of isolation and loneliness. However, any marriage entered into as an escape cannot prove entirely successful. The sad fact is that marriage seldom solves one's problems; more often, it merely worsens them. Furthermore, it is doubtful whether the home is capable of carrying all that the young are seeking to put into it; one might say that they are abandoning one idol only to worship another. Young people correctly understand that their parents are wrong in believing that success is the ultimate good, but they themselves are wrong in believing that they have found the true center of life's meaning. Their expectations of marriage are essentially unrealistic and therefore incapable of fulfillment. They want too much, and tragic disillusionment (幻想破灭) is often bound to follow.
Shall we, then, join the chorus of those against early marriages? One cannot generalize: all early marriages are not bad any more than all later ones are good. Satisfactory marriages are determined not by how old one is, but by the emotional maturity of the partners. Therefore, each case must be judged on its own merits. If the early marriage is not an escape, if it is entered into with relatively few illusions or false expectations, and if it is economically practicable, why not? Good marriages can be made from sixteen to sixty, and so can bad ones.
