appear through smoke and mirrors? I find that if I try to be something I"m not. I feel unsure of myself and
take out a part from my PBA (personal bank account). I love how singer Judy Garland put it. "Always be
a first-class version(版本) of yourself, instead of a second-class version of somebody else."
Then there"s honesty in our actions. Are you honest at school, with your parents, and with your boss?
If you"ve ever been dishonest, I think we all have, try being honest, and notice how whole it makes you
feel. Remember, you can"t do wrong and feel right. This story by Jeff is a good example of that:
In my second year of study, there were three kids in my math class who didn"t do well. I was really good
at it. I would charge them three dollars for each test that I helped them pass. I"d write on a little piece of
paper all the right answers, and hand them off.
At first I felt like I was making money, kind of a nice job. I wasn"t thinking about how it could hurt all
of us. After a while I realized I shouldn"t do that anymore, because I wasn"t really helping them. They weren"t
learning anything, and it would only get harder down the road. Cheating certainly wasn"t helping me.
It takes courage to be honest when people all around you are getting away with cheating on tests, lying
to their parents, and stealing at work. But, remember, every act of honesty is a deposit (储蓄) into your PBA
and will build strength.
B. to be unreal
C. to become clear
D. to come from an imagined world
B. Don"t copy others or you can"t be the first class.
C. Make efforts to be the first instead of the second.
D. Don"t learn from others unless they"re excellent.
B. A bad thing can be turned into a good one.
C. Helping others cheat can do good to nobody.
D. Be honest in our actions and feel right.
B. it"s difficult to be honest when others are not
C. one should be honest when making a deposit
D. honesty in one"s actions can help him in the future

Is ripening fruit a self-contained system, or is the rate of these changes affected by the environment? We
designed the experiment below to see if different atmospheres, produced by different packaging, affected the
rate of ripening. You will vary the atmosphere surrounding unripe bananas and observe the effect on the ripening
process.
Now set up the bananas in their environments as follows: 1. Put two green bananas in a paper bag and fold the top over to seal out the air. 2. Put one green banana and the very ripe banana in the other paper bag and fold over the top. 3. Put two green bananas in a plastic bag and seal it. 4. Wrap (包) one green banana tightly in a plastic bag. 5. Leave one green banana exposed to the air. | |

Surgeons in Spain have successfully carried out the world"s first organ transplant (移植) using new stem cell technology. Some people are calling it the greatest medical breakthrough so far this century. But what are stem cells? As we know, most cells in our bodies are designed____ -for example, a liver cell develops to work in the liver and cannot become a heart cell. But stem cells are different. They are very young and in the laboratory scientists can grow them into different types of cells. Claudia Castillo needed a new windpipe (气管) after getting a serious disease. Scientists from the University of Bristol took a donor windpipe, from someone who had recently died. They used strong chemicals to remove the donor"s cells, leaving a tissue scaffold (组 织支架). This was refilled with cells from Ms Castillo"s windpipe and stem cells from her bone. After four days the cells had grown sufficiently for the windpipe to be transplanted into Ms Castillo. Currently, transplant patients have to take drugs for the rest of their lives to prevent their bodies rejecting the new organs. These drugs can have bad side-effects, and do not always prevent rejec tion. But by using Ms Castillo"s own cells, doctors were able to trick her body into thinking the new windpipe was her own organ. Five months on, Claudia Castillo is in perfect health. This ground-breaking procedure could be used in other trans- plant operations in the future. Scientists also believe stem cells might be used to treat Parkinson"s disease, heart disease, stroke, ar thritis, burns and so on. However, stem cell research is extremely controversial. The most effective stem cells do not come from adults but from embryos (胚胎) created in laboratories which are just a few days old. Many people have religious or ethical objections to growing embryos, even if they can be used to cure diseases. | |

Many people believe that they 1 (suppose) to drink eight glasses of water 2 day, or about two liters. Why? Because that is 3 they have been told all their lives. 4 a new report offers some different advice. The experts say people should obey their bodies; they should drink as 5 water as they feel like drinking. The report contains some general 6 (suggest). The experts say that women should get about 2.7 liters of water 7 (day). Men should get about 3.7 liters. But wait in each case, that is more than eight glasses. There is an important difference. The report does not tell people how many glasses of water to drink. 8 fact, the experts say that 9 may be impossible to know how many glasses are needed to meet these guidelines. This is because the daily requirement can include the water 10 (contain) in foods. | |

We live in a digital world now, and a student"s technology needs have changed. For the early years, say when you are in primary school, you can get by with no technology at all. Even if you have a computer, it"s a good idea to get children familiar with libraries. At this age, trips to the library are like family outings. As you get closer to middle school, a computer with Internet access becomes more of a necessity. Teachers will often give assignments that require a student to use the Internet for research. After a computer, technology choices for students become more difficult to make - especially when it comes to cellphones. Kids will beg their parents for a cell-phone, especially in middle school. For many parents, it"s a safety issue: They want to know that their kids can reach them quickly if necessary. For teachers, cell phones can be used to record lessons when students are absent. But many teachers dislike cell-phones. Some kids send messages or have talks in the class. Sending messages also raises the problem of cheating on exams. More and more schools are now forbidding the use of cellphones. Many kids see iPods as necessary things to have. iPods are great for music, but do they do anything good for your children"s education? Maybe they do. That"s the opinion of Doug Johnson, an educator for 30 years. Johnson says that educators should accept all new forms of technology in the classroom, including iPods. "Some do more with their cell- phones than we can do with our laptops," he jokes."I don"t think we should be afraid. The truth is that it"s easier to change the way we teach than to change the technology habits of an entire generation." | |
