What weighs 3500 pounds(1600kg)and lived 60 million years ago?Are you thinking of
dinosaurs?Guess again!You don,t have to go to a museum to see these creatures．They are alive
and swimming in the warm coastal waters of Florida．
Manatees(海牛)have lived a peaceful existence in the warm waters of Florida for 60
million years．However，they are now an endangered species．This means that if humans don,t do
something to save them，they will soon go the way of dinosaurs．
Humans have made life very difficult for manatees．One big danger that humans have
introduced is the speedboat．Because manatees are mammals．they need to come to the surface to breathe about every 5 to 6 minutes．This means that they are in constant danger of being caught in the propellers(螺旋桨)of speedboats．And boating aceidents are the greatest cause of death for them．
Manatees are in extra danger when they are in their sleeping or“torpor”state．They still
have to come to the surface for the air，but sometimes they are too sleepy to avoid the danger of approaching boats．
Another danger for manatees is the pollution that humans produce．Due to human pollution，
a deadly plant called red tide had increased greatly in the Gulf of Mexico．The plant，or algae，
t11riVes(繁茂)on pollution．It wiped out nearly 20 percent of the total manatee population on
earth．
Humans can help to save manatees。The government has established boating speed limits to
give the manatees．a chance to escape approaching speedlsoats．Everyone can help by cutting
down on waste and pollution to protect the waters for the manatees．
One famous singer，Jimmy Buffet，has helped save the manatees．He co-founded the Save the Manatee Club(SMC)．SMC had begun an adoption(收养)program for the manatees．For a fee，sponsors(资助者)can name a manatee．Donations are used to help protect the manatees and their habitat．
45．The manatee is the kind of animal that___________．
A．1ikes living in the cold waters of Florida B．will die out if not protected in time
C．call dive in the deep sea for hours D．is the biggest living animal on earth
46．Why is it dangerous for manatees to be in a torpor state?
A．Because they come to the snlface to breathe，and that is when they are hunted．
B．Because they eat deadly algae，and this makes them too sick to avoid danger．
C．Because they live in groups and therefore they are easily hurt by passing boats．
D．Because they are sleepy when they surface，so they can,t avoid approaching boats．
47．The death of the manatees is largely due to__________．
A．human hunting B．human pollution
C．speedboat accidents D．deadly plants
48．To help protect manatees，people should_________．
A．never go speed boating in their living habitat
B．keep the waters of Florida free from pollution
C．have manatess named by sponsors without a fee
D．wake manatees up from their torpor state
Astronauts’ meals have come a long way from the free-dried powders and semi—liquid pastes of decades ago，now US scientists want to grow vegetables in mini—greenhouses on the moon．
Scientists say they are looking forward to a time when residents of future lunar or even Martian outsteps will be able to dine on fresh vegetables．Paragon Space Development Corporation has unveiled what it called the first step toward growing flowers——and eventually food on the moon．
This is a sealed greenhouse that looks like a bell jar encased in a 46-cm triangular aluminiumframe．It is designed to safely land a laboratory plant on the lunar surface，and protect it while it grows．
The miniature greenhouse is to be launched into space by Odyssey Moon Ltd, a participant in the Google Lunar X Prize. This competition offers $21 million to any entrant who can launch, land and operate a rover on the lunar surface.
Paragon officials say future testing of the “Lunar Oasis” will be driven by Odyssey’s flight Schedule, which will not happen until 2012 at the earliest．
When it does lift off the greenhouse will contain the seeds of Brassica, a hardy plant related to Brussels sprouts and cabbage. Because Brassica goes from seed to flower in just 14 days, it can complete its life cycle in a single lunar night.
“Colonizing the Moon or Mars seems so far away，but it is important that we do this research now. ”Paragon president Jane Poynter said．
“It takes a long time to get a lot of research, and to get integrated, reliable efficient systems before colonists move in. ”she said．The article is written mainly to__________．
| A．predict the astronauts’ meals in the future |
| B．introduce an experiment “Lunar Oasis’’ |
| C．tell us the future development of astronomy |
| D．focus on the human’s great progress |
The article implies that__________．
| A．astronauts can grow flowers in space at present | |
| B．Paragon and NASA will carry out the test separately | |
C．Lunar Oasis is a series of experiments carried out in space |
D．the earliest testing of the Lunar Oasis may be in 2012 |
The underlined word “colonists” in the last paragraph probably has the meaning of______．
| A．plants | B．wild beasts | C．human beings | D．scientists |
The seeds of Brassica will be contained in the greenhouse mainly because _________.
| A．their life cycle is much shorter |
| B．they are more nutritious than other food |
| C．they are related to Brussels sprouts and cabbage |
| D．they are very delicious |

Depression(抑郁症)is a serious problem today．Depression causes workers to be unproductive，causing companies and countries to lose billion of dollars．One expert says that depression is like cancer because it is “widespread, costly and deadly”．Depression hits one person in five around the world．
Although people have believed depression to be a problem among the rich and educated，studies show that depression is a problem among everyone．Over any six-month period, between five to seven percent of the world’s population will be suffering from a serious depression．
Suicide(自杀)rates among people suffering from the disease in its extreme, or clinical form were 80 percent higher than in the population at large, and sufferers were four times more likely to have heart attacks．People who suffer from depression often have problems sleeping，getting up on time，and doing work productively.
Depression, which researchers agree has its origin in the genes(基因)，brings loss of confidence and ability to concentrate, making it possible for employees and managers to work efficiently．
Depression is made more serious in China by Chinese’s inability to face it．Many people believe that depressed people are either weak or lazy．Besides，there is no good treatment，with few specialists available．
“Most patients in China just don’t get help,” a Chinese doctor says．“In my hospital，I have
to see 30 or 40 patients in a morning，and just have time to say ‘Hello，how do you feel ?…’”
In Western countries，people are not afraid to admit that they have depression，but most do not tell it to their boss，because they fear that their boss would fire them．
“In my e
xperience，aging bosses are the most willing to admit they have it, because they feel
the most secure about themselves, ” an American doctor says．
Hopefully，in the near future，people around the world will be able to admit that they have depression so that they can get the right treatment.Which of the following is TRUE according to the passage?

Compared to normal people，depressed people are likely to be________．
| A．very unconfident and often absent-minded | B．easy to avoid being hit by heart attacks |

The trend in everyday conversation is to use grandiose(夸大的)words．“Outstanding” is the
new “good,” “amazing” is the new “OK, ” and “huge” is the new “big.”
I was in a restaurant in Washington D．C．last weekend and every question I asked was answered with exaggeration．
Me：How is the salmon?
Sever：Fantastic!
Me：Does it come with rice?
Sever：Absolutely!
Would a “good” and a “yes” have been enough? Of course!
My father is an average-sized man．He hasn’t gained weight or height for the past 30 years. Therefore, his size remains the same．However，in the same amount of time，his T-shirt size has gone from small to medium to large to extra large．
The reason for the exaggerated word is clear：we are bored with our lives. We want the next
—next thing now．Immediately!
And we also want others to think that we still care，that we can still be delighted，that we know that everything is just great．Even when deep inside we know it can’t be．Everything can’t be great．
I’m not a scientist，so many methods of proof leave little to be desired，or a lot to be desired，or an immensity(无限)．
Listen to the voices around you．Listen to your own voices．There is nothing on the radio that is good or bad，weather is either beautiful or horrible．
Listen，the next time when someone asks you something and you agree，because when you
could simply say “yes”, instead you will say “absolutely’’ or “without doubt ” or “Oh，yeah，unquestionably ---- absolutely without doubt."
Have people forgotten what it is like to be OK? Simply OK with what they have and who they are? If everything is outstanding，if everything is the most amazing thing ever，is anything ever amazing at all?By telling his experience in the restaurant，the author intends to ________．
| A．show his interest in exaggerated words |

| C．they want to be different from others |
| D．they are brave in telling their true feelings |
According to the passage，if you approve of something，you’d better say “________”．

Many children first learn the value of money by receiving an allowance (pocket money). The purpose is to let children learn
from experiences at an age when financial mistakes are not very costly．
The amount of money that parents give to their children to spend as they wish differs from family to family. Timing is another consideration．Some children get a weekly allowance．Others get a monthly allowance．
In any case, parents should make clear what，if anything, the child is expected to pay for with the money．At first, young children may spend all of their allowance soon after they receive it. If they do this，they will learn the hard way that spending must be done within a budget．Parents are usually advised not to offer more money until the next allowance．
The object is to show young people that a budget demands a choice between spending and saving．Older children may be responsible enough to save money for larger costs，like clothing or electronics．Many people who have written on the subject of allowances say it is not a good idea to pay your child for work around the home．These jobs are a normal part of family life．
Paying children to do extra work around the house，however，can be useful．It can even provide an understanding of how a business works．
Allowances give children a chance to experience the three things they can do with money．They can share it in the form of gifts or giving to a good cause. They can spend it by buying things they want．Or they can save it.
Saving helps children understand that costly goals require sacrifice．You have to cut costs and plan for the future．Requiring children to save part of their allowances can also open the door to future saving and investing．Many banks offer services to help children and teenagers learn about personal finance.
A saving account is an excellent way to learn about the power of compound interest．
Compounding works by paying interest on interest．So，for example，one dollar invested at two per-cent interest for two years will earn two cents in the first year．The second years，the money will earn two percent of one dollar and two cents，and so on．That may not seem like a lot．But over time it adds up．Giving an allowance, parents should consider all the following EXCEPT_______.
| A．how much the child should get each time | B．whether the child has made a budget |
| C．where the money really goes | D．how often a child can get it |
The author of the passage holds the opinion that________.
| A．what children learn by handling allowances may be beneficial in the future |
| B．children can learn to set up their own business with their allowances |
| C．keeping allowances in the bank is the best choice for children |
| D．it is not a good idea to pay children for housework at home |
The underlined words “compound interest” in the passage probably mean ________.
| A．increasing curiosity to learn how to make more money |
| B．stronger power to hold one’s attention to saving money |
| C．money paid by the bank on your original money and the gain from it |
D．the sum of money that you earn from keeping your money in  the bank |
What is the best title for the passage?
| A．Be Generous to Pay Your Children． | B．Be Wise to Avoid Financical Mistakes． |
| C．Saving Allowances Does Good to Children. | D．Allowances Help Children Learn about Money． |
