Nowadays lots of students ask their parents for money to buy things they like. For me, to ask for money is like entering a(n) 36 . I learned this from 37 .
Last year my mother told me that the 38 way I would get a driver’s license before I turned eighteen depended on 39 I paid for the classes myself. “What?” I asked in 40 . Judging by the look on my mothers face, I knew 41 that my reasoning would have no 42 on the situation.
Three weeks later, I started working 43 a hostess at a factory, twice a week. A month later I paid $ 270 for driving lessons, and then over $20 to 44 my permit test-all paid for by 45 other than yours truly. My pockets were empty 46 as soon as they were filled.
My mother thought that I’d be 47 to do things without her help. The funny thing was that even though I was totally 48 in the beginning, I truly appreciated it, 49 if I had just been handed bills from her.
When I realized that my mother wasn’t going to 50 something like a driver’s license, at first, it seemed as if she had put an immovable 51 before me and I would never 52 it. But my mother was 53 . She knew that I wanted a luxury(奢侈品) but 54 me to get it. That is as 55 as this―if I really want it, I’ll find a way to get it myself.

Can people change their skin color without suffering like pop king Michael Jackson? Perhaps yes.Scientists have found the gene that determines skin color.
The gene comes in two versions, one of which is found in 99 per cent of Europeans.The other is found in 93 t0 100 per cent of Africans, researchers at Pennsylvania State University report in the latest issue of Science.
Scientists have changed the color of a dark - striped zebrafish(斑马鱼) to uniform gold by inserting a version of the pigment(色素) gene into a young fish.As with humans, zebrafish skin color is deter-mined by pigment cells，which contain melanin(黑色素).The number, size and darkness of melanin perpigment cell determine skin color.
It appears that, like the golden zebrafish, light - skinned Europeans also have a mutation (变异) in the gene for melanin production.This results in less pigrnented skin.
However, Keith Cheng, leader of the research team, points out that the mutation is different in hu-man ancl zebrafish genes.
Humans acquired dark skin in Africa about l.5 million years ago to protect bodies from ultra - violetrays of the sun. which can cause skin cancer.
But when modem humans leave Africa to live in northem latitudes, they need more sunlight on their skin to produce vitamin D. So the related gene changes, according to Cheng.
Asians have the same version of the gene as Africans, so they probably acquired their light skin through the action of some other gene that affects skin color, said Cheng.
The new discovery could lead to medical treatments for skin cancer.lt also could lead to research in-to ways to change skin color without damaging it like chemical treatment did on Michael Jackson.
