12．Imagine the tallest building in the United States．Fill that giant building 44times with rotten fruits and vegetables．Now you know how much food Americans waste every year．
It is hard to believe，right？About 133billion pounds of food get thrown away．That's one-third of all the food we produce．And a lot of it is thrown away for one simple reason：It's ugly．
The problem is that nature isn't perfect．Apples can get scarred（留下疤痕）by storms．Cucumbers grow in C shapes．Carrots change into unusual fork-like forms．Watermelons get too big to fit on a refrigerator shelf．These crazy-looking fruits and vegetables may taste great．But most grocery stores refuse to sell them．Store owners say people judge food by how it looks．No one wants a tomato that looks like a two-headed monster．But what if you could buy that tomato for half-price？
A new movement is trying to make people see the"beauty"in ugly food．Some stores are selling ugly produce．It tastes the same．And you pay less for it because the food doesn't look perfect．
Usually，the stores find a nicer word than"ugly"．A Canadian chain uses"naturally imperfect．In some US stores，it's"misfit produce"．Whatever you call it，ugly food helps many people．Farmers get paid for food they were going to have to throw away．Shoppers get cheaper fruits and vegetables．The ugly-food movement will also help some of the 44million Americans who don't have enough to eat．Many groups give the ugly produce to hungry people．
So really，who cares if that carrot looks a little…ugly？

28．Why are lots of fruits and vegetables thrown away in the US？A
A．Because they don't look nice．
B．Because they have gone bad．
C．Because they don't taste good．
D．Because they are badly polluted．
29．What is the 5th paragraph mainly about？D
A．The stores selling ugly food．
B．The better names for ugly food．
C．The number of hungry Americans．
D．The benefits of the ugly-food movement．
30．What does the mark"…"in the last paragraph suggest？C
A．The author would like to buy ugly carrots．
B．No one would care if a carrot looks a little ugly．
C．The author does not quite like the word"ugly"．
D．Nobody really wants to buy carrots that look ugly．

9．Monty Hempel is a professor of environmental science at Redlands University in California．He studies ecological literacy-or ecoliteracy （生态素养） for short．Ecoliteracy is the ability to think about and understand the natural processes that make life possible．
Monty Hempel says ecoliteracy gives people knowledge about environmental problems．But he says it does not always work to get them to change their behavior．
Mr．Hempel wrote part of the World watch Institute's latest State of the World report．He says in his article，"Some people think that ecoliteracy is just a green form of science literacy．And what I have tried to ask is whether that's enough．In other words，what an ecologically literate person needs to know might include things like the cycles and the flows，the energy systems，all of those kind of things that we would call the science of ecology．"
"That doesn't seem to lead to action to protect our environment-to protect our life-support system to the level that we need to．Just because that we know，a lot about the environment doesn't mean that we actually act to save it．After all，actions speak louder than knowledge．"
He adds that people may not be very worried about environmental problems if they seem far away．"Some people call it psychological distance．A lot of climate issues （问题） are worse in the Arctic and most of us don't spend time in the Arctic．And so，there^a certain distance．But there's also a distance that's happening in the world as it urbanizes （城市化）-people spending more time in front of screens and less time out in nature．We become，if you will，disconnected from the natural systems that used to be the key to success for a human being．"
To help children discover the wonders of nature，children should learn about nature in school，he adds．But he also points out there is a high mountain for people to climb from knowledge to action．

32．From what Monty Hempel says in Paragraph 3，we learn thatA．
A．ecoliteracy is more than a green form of science literacy．
B．people have learnt more knowledge about ecoliteracy．
C．ecoliteracy can greatly affect how nature works．
D．people with enough knowledge will better protect the environment．
33．In Mr．Hempel's opinion，which is the most important for environment protection？B
A．Knowledge．
B．Action．
C．Green living theory．
D．Psychological distance．
34．Mr．Hempel thinks people may show no concern about some environmental problems becauseD．
A．they lack knowledge on environment protection．
B．they are closely connected with the nature．
C．the problems are not serious at all．
D．the problems seem to be far away．
35．What can be inferred from the last paragraph？C
A．It is the best way to learn about nature in school．
B．Climbing a high mountain is a good way to exercise．
C．It is easier to understand environment protection than to carry it out．
D．people should first collect waste in the mountains to protect the environment．

2．When asked to name the one invention that would be impossible to live without，Americans did not pick their phone．They didn't pick their car．They picked their toothbrush，according to the Lemelson-MIT survey．Hold up though．That survey was from 2003．So we conducted an informal survey of How Stuff Works staffers to find out if the toothbrush would still take the lead 14 years later．It did．The toothbrush got
11 votes，followed by the cell phone （5），computer （3），microwave （2）and car （2）．
You probably aren't amazed．The tiny toothbrush is an important product for a lot of modem cultures，and it comes by its popularity honestly； Versions of the toothbrush have been around since ancient Babylonian times．But note that these were not the boring plastic creations we take out of the box．
"The first tooth cleaning instrument seems to have been the‘toothpick'or more correctly small bones or slivers of bones，"writes Scott Swank，dentist and leader of the National Museum of Dentistry，in an email．
He points out that people used even less technical means，too．"Fingers wrapped in cloth have been used for ages to clean teeth，"he says．"An ancient Greek doctor recommended using a round woolen ball dipped in honey to clean one's teeth．''But not all recipes （配方） or early toothpaste were so sweet．
"Both the Greeks and Romans had recipes for toothpaste，"says Swank．We're here for the powerful toothbrush，and Swank says that the first real evidence of that comes from Babylon，around 2500-1800 B．C．The frayed （纤维状散开的） end of a stick or plant was used to brush the teeth．
We have to look much closer to our own times to find a brush we might recognize．"The first device that we would consider people to use the modem toothbrushes was recorded in China in 1500，''says Swank．In 1780，the English merchant William Addis fashioned a modern"toothbrush"and began mass-producing them in England．Sounds too good to be true？"I have no reason to doubt the story as a whole，''Swank says．"It could have become a bit different over time but I think，on the whole，it stands up．"

32．According to the passage，how many HowStuffWorks staffers at most took part in the survey？D
A.5 B.11 C.12 D.23
33．The underlined words in the second paragraph probably refer toD．
A．different techniques of making the toothbrush
B．different steps to make the toothbrush
C．different periods of making the toothbrush
D．different makes of the toothbrush
34．Which of the following can NOT be inferred from the passage？D
A．The survey was conducted in the year of 2017．
B．The most recent survey showed the toothbrush is still considered an important invention．
C．Records showed the Chinese people were the first to use modem toothbrushes．
D．Scott Swank didn't at all believe the way modem toothbrushes got spread．
35．What may well serve as the title of the passage？C
A．What was used to make the toothbrush？
B．How long was the history of the toothbrush？
C．How was the toothbrush historically developed？
D．Why was the toothbrush chosen as a daily necessity？

19．Prepackaged，mass-produced snack foods are hugely popular in grocery stores around the world，Many people are accustomed to choosing snack foods in grocery stores．
The first problem with packaged snack foods like cookies，crackers，and other bite-sized options is that they are often loaded with unhealthy materials．The reason for this is fairly easy to understand．Mass-produced foods need to be uniform in color，taste and so on．In order to achieve this uniformity，snack food producers use sugar，salt，and other chemical preservative（防腐剂） and coloring materials in large amounts．These materials contribute to a rather unhealthy food．
In addition to requiring uniformity of taste and appearance，mass-produced snack foods like potato chips and candies need to be shelf stable．Preservatives and complex packaging make products shelf stable，but this stability and non-perish ability（抗腐性） often come at the expense of nutrition．
One reason that pre-made snacks are so popular in grocery stores is their prices．Food producers can keep costs down by using established production facilities and processes to quickly produce a huge amount of food．Shoppers are drawn to what they see at low prices．
People who are interested in improving the quality of their snacking can use magazines，books，and the Internet to discover a lot of healthy snacking tips and ideas．Even television shows about health and food sometimes talk about healthy snacking alternatives．Some healthy snacks，like fresh fruit，require no preparation at all．
Once people are aware of the drawbacks of clearly cheap and easy snack foods，they can start turning to better options．Soon，perhaps，the old and unhealthy snack options will no longer be profitable for food producers．
