Passage Two
America put more people in prison in the 1990s than in any decade in its history. That started a debate over the wisdom of spending billions of dollars to keep nearly 2 million people locked up. According to statistics, the United States ends 1999 with 1983084 men and women in prisons. That shows an increase of nearly 840,000 prisoners during the 1990s and makes the United States the country with the highest prisoner population in the world. With the cost of housing a prisoner at about $20,000 a year the cost in 1999 for keeping all these prisoners behind bars is about $39 billion.
Some experts argue that the money is well spent, saying the cost of keeping prisoners behind bars doesn't seem much in comparison in the 1990s coincided with (与……相一致) a steady drop in the US crime rates. It is reported that serious crime has decreased for seven years in a row. "There are noticeable number of people who don't do crimes because they don't want to go to prison," they say.
36. There is a heated debate among American experts because ______.
A. America has put 2 million people in prison
B. the cost for housing a prisoner keeps rising
C. billions of dollars has been spent on prisoners
D. the prisoner population is the largest in the world

The atomic veterans and their families, as well as researchers and policy-makers, continue to struggle for definitive answers. These have been elusive, at least in part, because a crucial piece of information has been difficult to get-the radiation dose that each individual received.
In the largest study to date, researchers from the Institute of Medicine (IOM) have come up with some partial answers. But they too were limited in their ability to draw conclusions by the lack of usable information on radiation exposure.
The new study focused on participants in five series of nuclear tests, all of which took place either in the Nevada desert or the South Pacific. Nearly 70, 000 soldiers, sailors, airmen, and marines were involved in at least one of these, and about 30 percent of them have now died. For comparison, researchers selected a group of 65, 000 military people serving at the same time under similar conditions, except that they did not take part in nuclear tests.
After an intensive review of service and death records, researchers found no difference between the two groups in overall death rates or in total deaths from cancer. Had there been a dramatic radiation effect, it would have shown up in this comparison.
The researchers also analyzed specific causes of death, including diseases linked in other studies to radiation. Here there were some differences. Among the nuclear test veterans, 14 percent more died from leukemia than those in the comparison group, although the difference lacked statistical significance and could have resulted from chance.
When comparisons were made based on whether the veterans participated in nuclear tests in Nevada or in the Pacific Ocean, the differences were sharper: a 50 percent higher leukemia death rate among Nevada atomic veterans than among the comparison group. This was not true among Pacific test participants, who actually had a slightly lower, though not statistically significant leukemia death rate than those in their comparison group.
81.The passage tells us that researchers wish that they could find out______.
A.when and where the veterans received the nuclear radiation
B.why the amount of radiation cannot be accurately measured
C.who was responsible for the veterans' deaths
D.how much radiation each veteran got during the nuclear tests
82.The latest study includes a comparison made between______.
A.healthy veterans and unhealthy veterans
B.nuclear test participants and those with no radiation exposure
C.the veterans who are still alive and those who have died
D.people who died of cancer and people who took part in atomic tests
83.What can we learn about the result of the latest study?
A.There was a significant difference in total deaths from cancer between the two groups.
B.There was no significant difference in death rates between the two groups.
C.The comparison group has a lower death rate.
D.More veterans died from leukemia than from other cancers.
84.One comparison mentioned in the last paragraph was made between______.
A.Pacific test participants and those who undertook the Nevada test
B.Nevada atomic veterans and those who didn't take part in any nuclear tests
C.Veterans in Nevada and Pacific atomic tests and the comparison group
D.half of Nevada test participants and half of the group of no test participants
85.How different is the group of Nevada test participants from their South Pacific counterparts?
A.The former shows a higher leukemia death rate than the comparison group.
B.The former shows a lower leukemia death rate than the comparison group.
C.The former shows a higher death rate than the latter.
D.The former shows a lower death rate than the latter.

THE COMPANY LEADING THE FUTURE OF FARMING
Here's a crazy idea: Combine bioprinting and tissue engineering to "print" animal products and tackle some of the planet's biggest problems. Animal farming, after all, accounts for about half of all human-caused greenhouse gases, taking place on one-third of the available, non-frozen land on Earth. All to feed people's appetites for 300 million tons of meat a year.
Modern Meadow is a Missouri-based startup that engineers tissues to create lab-grown edible meat, in a process that eliminates many of the negative environment effects associated with traditional livestock practices.
The company claims that by carefully layering mixtures of cells of different types in a specific structure, in-vitro meat production becomes feasible. It’s set a short-term goal of printing a sliver of meat around two centimeters by one centimeter, and less than half a millimeter thick, which is edible.
The company explains in a submission to the United States Department of Agriculture: “The technology has several advantages in comparison to earlier attempts to engineer meat in vitro. The bio-ink particles can be reproducibly prepared with mixtures of cells of different type. Printing ensures consistent shape, while post-printing structure formation and maturation in the bioreactor facilitates conditioning.”
However, it admits that the road ahead is strewn with difficulties. “The consumer acceptance of such products may not be without challenges. We expect it will first appeal to culinary early-adopter consumers and the segment of the vegetarian community that rejects meat for ethical reasons. With reduction in price, it can reach the masses with religious restrictions on meat consumption (people restricted to Hindu, Kosher, Halal diets) and finally populations with limited access to safe meat production.”
Whatever the final outcome, lab-grown edible meat is no longer in the realm of science fiction. It is coming.
1. Animal farming is responsible for the occurrence of greenhouse gases.{T; F}
2. Modern Meadow is a newly-started business which aims to make profits by producing lab-grown edible meat.{T; F}
3. The method Modern Meadow adopted to produce in-virto meat is by layering mixtures of cells of different types in a specific structure.{T; F}
4. There is no meat engineered outside living bodies before.{T; F}
5. This lab-grown meat has already widely received by the masses.{T; F}

第7题
Credit card companies,too,quickly saw the potential for online shopping,and have installed things like online shopping insurance for people. If you ever have a problem with your online credit purchases,many credit card companies will happily refund(退还) your money and then set their claws on the company that wronged you. Now that’s buying power!
There are other bonuses for online shoppers,of course. No lineups,for one. No annoying mall shopping carts with broken wheels and kids crying because their parents won’t get them what they want.
When shopping online,consumers can sit down,have a coffee,and wear their slippers,not having to worry about their hair or parking,and just clicking through sale after sale. Comparison shopping couldn’t be any easier. And thanks to courier companies(快递公司) getting in on the act,you never need to wait longer than a day or two to get those all important purchases delivered right to your door.
No wonder so many companies are shaking their heads at traditional retailing and instead looking to the “virtual” world to attract online shoppers.
1.The underlined word “leery” in the first paragraph means being very sure.()
2.Consumer confidence in online shopping mainly relies on security in shopping.()
3.Internet giants, traditional retailers, courier companies and credit card companies have made contributions to the popularity of online shopping.()
4.The author think of the current online shopping as safe, convenient and fast.()
5. Nowadays many companies are trying to cooperate with the online shoppers instead of traditional retailers.()
