Computer hackers (黑客) have now got their hands on mobile phones. A phone virus (病毒) can 1 your
phone do things you have no control over, computer security (安全) experts 2 . It might 3 the White
House or the police, or forward your personal address book to a marketing company. Or it could simply eat
into the phone"s operating software, turning it 4 and erasing your personal information. Similar viruses have
already made mobile phone owners 5 . in Japan and Europe.
Ari Hypponen, chief technical officer of a computer security in Finland, said a virus can get your 6 and
send them elsewhere. And it can record your 7 . Mobiles are now able to surf the Net, send emails and 8
software, so they are an easy 9 for the same hackers who have sent viruses to computers over the last
decade. "It"s technically 10 now," said Stephen Trilling, director of research at anti-virus 11 maker
Symantec Corp based in the US."If the phone is connected to the 12 , it can be used to transmit threats and
13 targets, just as any computer can."
In Japan, if you opened a certain email message 14 your mobile, It would cause the phone to repeatedly
15 the national emergency number. So phone operators had to 16 emergency calls until the bug was
17 .
In Europe, mobile"s short message service, 18 SMS, has been used to send codes that could damage
phones.
Mobile users can 19 viruses, of course, by sticking to their traditional phones 20 Web links, some
experts said. |

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. | | 1. The underlined part "appear through smoke and mirrors" in the first paragraph means "_____". | A. to be honest
B. to be unreal
C. to become clear
D. to come from an imagined world | | 2. Which of the following can best explain Judy Garland"s words? | A. Be your true self rather than follow others.
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. | | 3. What does the author expect to show by Jeff"s story? | A. Honesty can be of great help.
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. | | 4. In the last paragraph the author mainly wants to express _____. | A. one must be brave to be honest
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 | | 阅读理解。 | As bananas ripen, the green skin turns yellow gradually. Chemical changes occur in the flesh of the fruit
as well: starch (淀粉) changes to sugar; pectin (果胶) breaks down, losing its stiffness; and the flesh softens.
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. |  | 阅读表达。
阅读短文，请根据短文后的要求答题。（请注意问题后的字数要求） | 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. | 1. What"s the best title for the passage? ( Please answer within 8 words. )

_______________________________________________________________________________________ | | 阅读理解。 | Most sharks are dangerous. The largest kind of sharks-the whale shark-has small teeth and is quite harmless
to people. However, blue sharks, tiger sharks, white sharks and hammerheads are enemies of man. Man-eaters
are always a danger to swimmers in shark waters. Sometimes, though, men have used strange methods when
they"re suddenly faced with a shark.
During world War Ⅱ, soldiers and sailors whose boats or planes were destroyed drifted (漂流) helplessly
on the ocean in small rafts (筏子). While waiting to be saved, the men had to struggle to stay alive and were
often attacked by sharks. In some cases, they had few weapons to protect themselves with. They found that
just splashing (溅水) water seemed to help keep the sharks away.
One sailor was swimming for his life in the Atlantic Ocean after his boat had been blown up. He saw a
shark swimming towards him. He hit the shark with his bare fist, and that drove it off.
Once, in Australia, a fisherman was fishing after sunset. He hooked a big fish and drew it towards the shore. His line broke when the fish was only a few yards from the shore. The fisherman waded (涉水) into the water
to try to catch it with his hands. In the dim light, it looked like the kind of fish that could be dealt with without
danger.
He put his arms around the fish and wrestled with it. Dragging it to the beach turned out to be harder than
he had expected, but at last he pulled it in. When he turned a light on it, he was amazed. He had caught a shark.
It was small for a shark, but it was the man-eating type and was about as long as a tall man. In a word, the
best way to deal with sharks is to keep far away from them. | | 1. The shark that is least dangerous to man is the _______. | A. white shark

C. splash water

B. about sharks
C. how to eat sharks
D. that sharks are man"s enemies | | 语法填空。 | 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. | 最新试题
