21、It’s not always easy to decide on a college to apply to or attend. By following the steps below, you can choose the right college and feel good about your decision.
Make a College List. Early in the process, sit down with your parents or someone you trust, such as your teacher, to develop a list of colleges that interest you. 【1】 You’ll want to consider a variety of experiences and outcomes before making a final decision. Ideally, this list should include 10-15 colleges.
Rank Your Wants and Needs. 【2】 For instance, you may want a Big 10 experience with a large student body and plenty of campus activities.
Visit College Campuses. The Internet remains an incredible resource for researching colleges and universities, learning about degree programs, and getting to know faculty and staff. Still, looking at a school’s website does not provide the same insight as visiting the campus in person. 【3】
Compare Financial Aid Offers. After applying to the colleges on your shortlist, you must wait for acceptance letters and financial aid award letters to arrive. 【4】 By evaluating financial aid award letters and comparing annual costs, you can get a clearer sense of your true out-of-pocket costs.
【5】 After completing the steps above, it’s time to sit down with a trusted advisor to weigh and see which one best meets your criteria. Gathering enough information about your target schools can better prepare you to choose your college and find an institution that’s the best fit for you.
A．Consider whether you want to live in a rural area.
B．Weigh the advantages and disadvantages of each college.
C．This is also unfair to other students who may be on waitlists.
D．Knowing what you need can help cut the number of your schools.
E．This list can include public and private schools, both local and out of state.
F．Besides funding from the government, you can receive financial aid from schools.
G．By exploring college campuses, you and your family can get a better feel for the decision.
22、
Bacteria are the one of the main food poisoners. So, to get food on the table safely, you need to know and follow the rules for food care.
KEEP FOOD HOT
High food temperatures (165°F to 212°F) reached in boiling, baking, frying, and roasting kill most food poisoning bacteria. If you want to delay serving cooked food, though, you have to keep it at a holding temperature - roughly 140°F to 165°F. Steam tables and chafing dishes are designed to maintain holding temperatures. But they don’t always keep food hot enough. So it’s not wise to leave hot food out more than 2 hours.
When cooked food is left out unheated, the possibility of bacterial growth is greater, since the food quickly drops to room temperature where food poisoners multiply.
To serve hot foods safely - particularly meat and poultry, which are highly affected by food poisoning - follow these rules:
• Cook thoroughly - Cook meat and poultry to the “doneness” temperatures given in the above chart. To make sure that meat and poultry are cooked all the way through, use a meat thermometer (温度计). Insert the tip into the thickest part of the meat, avoiding fat or bone.
• Don’t interrupt cooking - Cook meat and poultry completely at one time. Partial cooking may encourage bacterial growth before cooking is complete.
• Cooking frozen food - Allow frozen food more time to cook - generally 1.5 times the period required for food that has been thawed (解冻).
【1】At what temperature do bacteria grow the fastest?
A．40ºC~ 60ºC.
B．60ºF~125ºF.
C．40ºC~ 140ºC.
D．125ºF~140ºF.
【2】To keep food safe, it is suggested that ______.
A．hot food should not be left out over two hours.
B．frozen food should be thawed with a microwave oven.
C．raw ham should be cooked to the “doneness” temperature at 71ºF.
D．steam tables and chafing dishes should be used to keep food hot enough.
【3】What can be learned according to the guideline?
A．The only way to ensure food safety is to keep it hot enough.
B．High food temperatures above 74ºC destroy most poisoning bacteria.
C．Compared with goose, ground beef should be cooked to higher temperatures.
D．Insert the tip of a thermometer into the thickest part of the fat to control the temperature.
23、 Calling someone a “birdbrain” is considered rude. It implies that someone has a small brain and thus is not smart. A new study found that the expression doesn’t do birds justice either: Birds’ brains are much bigger than we thought — at least compared to their small bodies.
An international team of 37 scientists measured the brain volume (脑容量) of hundreds of dinosaurs and extinct birds by scanning fossils of their skulls. The readings were compared to a large database containing the brain sizes of modern birds. These measurements were then analyzed, taking into consideration each bird’s body size — resulting in something called “relative brain size”. The results showed that a dramatic change of birds’ body size happened right after the mass extinction of dinosaurs 66 million years ago.
According to the study, published on April 23 in the journal Current Biology, birds and dinosaurs had similar brain sizes before the extinction. After the extinction of the dinosaurs, however, birds had to find a way to survive, so they shrank their bodies — since smaller animals need less food — but they kept their big brains.
“The changed landscape may have caused the rapid evolution of new brainbody scaling patterns (缩放比例) by favoring both larger brains and smaller bodies,” US paleontologist (古生物学家) Daniel Ksepka, who is the lead author of the study, told CNN.
This “evolutionary brain leap” — as scientists call it — also happened very rapidly. Without dinosaurs, birds quickly repopulated. They came in all types and sizes, which contributed to the diverse species of birds we see today.
But among all the bird species, certain ones “show above average rates of brain and body size evolution”, study co-author Adam Smith at Clemson University, US, said in a statement — with crows and parrots being the most evident. In fact, previous studies have already discovered that these birds have an amazing cognitive capacity (认知能力). They are able to use tools, imitate human speech and even remember human faces.
So, in the words of Smith, “calling someone ‘birdbrained’ is actually quite a compliment (恭维)”!
【1】How did the scientists learn the brain sizes of dinosaurs and extinct birds?
A．By studying their fossil skulls.
B．By searching the database.
C．By experimenting on their brains.
D．By analyzing their body size.
【2】How did the birds change after the extinction of the dinosaurs?
A．The birds’ bodies shrank as their brains became smaller.
B．The birds’ bodies became larger while their brains became smaller.
C．The birds’ brains remained almost the same as their bodies shrank.
D．The birds’ brains became larger to adapt to the environment.
【3】According to Adam Smith, calling someone “birdbrained” is ________.
A．to make rude remarks
B．to laugh at one’s small body size
C．to praise one’s intelligence
D．to suggest the person is not smart
【4】What is the purpose of this text?
A．To describe how birds’ evolution happened.
B．To explain the origin of the word “birdbrain”.
C．To show the amazing abilities of bird species.
D．To present the latest study on birds’ brain size.
24、 As of October, President Donald Trump's administration announced that the gray wolf would be removed from the U.S. Endangered Species List.
Once abundant across most of North America, gray wolves went nearly extinct due to poisoning, hunting, and trapping, as human settlements expanded across the continent. At one point, hunters were awarded for killing gray wolves which were seen as threats to animals on rural ranches（牧场）and farms.
In the 1970s, as gray wolf populations continued to dwindle, the U.S. government took protective action, listing the animals as endangered. In 1995 and 1996, the government reintroduced gray wolves in Idaho and Wyoming's Yellowstone National Park. From these locations, gray wolf populations expanded to northern California, Oregon, Montana, and Washington State. As of today, according to data from the U.S. Fish and Wildlife Service, the total gray wolf population stands at 6000.
However, environmentalists have strongly criticized the gray wolfs removal from the Endangered Species list. They view the decision as premature and potentially hurtful to wolves, who have not yet gained a strong foothold in many ecosystems.
Colorado, a former reserve for gray wolves, has narrowly passed a vote to reintroduce gray wolves in the state's forests and mountain ranges. Wolf supporters and conservationists connect the animals' benefits with the environment. Gray wolves help maintain healthy elk and deer populations and help limit overgrazing, which can lead to soil erosion. Wolf opponents, on the other hand, fear increased livestock deaths and greater risk to farmers and rangers in rural areas because hunting and livestock raising arc among the biggest careers in western states.
【1】What can be learned from the text?
A.Human activities once caused a decrease in gray wolf populations.
B.Hunters who kill gray wolves will be awarded by the government.
C.In the 1990s most of the gray wolves in America lived in preserves.
D.Environmentalists think the government's new decision is sensible.
【2】What does the underlined word "dwindle" in paragraph 3 probably mean?
A.Multiply. B.Disappear.
C.Decline. D.Expand.
【3】Which can best describe Coloradans' attitudes to bringing in gray wolves?
A.Indifferent. B.Contradictory.
C.Ridiculous. D.Unconcerned.
【4】What's the main idea of the text?
A.Gray wolf populations have grown steadily.
B.Gray wolves play a key role in a balanced ecosystem.
C.Gray wolves experienced rise and fall in American history.
D.Gray wolves will be removed from the Endangered Species List.
