26、Yesterday, people on the social media site Twitter reacted with surprise and humor to a report that claimed, “Scientists have taught spinach to send emails.” That’s not exactly true, but the “news” is based on some amazing work done by MIT (Massachusetts Institute of Technology) scientists in 2016, and it’s still worth learning about.
Scientists at MIT have managed to change ordinary spinach plants into natural sensors which can detect chemicals used in bombs. Using a cheap and small computer system, the spinach can even send a warning email.
The secret to giving spinach these special powers is nanotechnology. For this experiment, the scientists placed two different kinds of nanotech materials into spinach plants: some were tiny sensors; others were tiny tubes called carbon nanotubes. To get the tiny materials into the plants, the scientists put a liquid containing the nano-materials on the bottom of the plants’ leaves. That’s where the plants normally take in CO2 gas.
Once the tiny sensors and nanotubes were in the spinach leaves, the plants did the rest of the work. As part of their natural process, the spinach plants pull water through their roots and into their leaves. If the water contains certain chemicals that are used in bombs, the sensors in the leaves make the nanotubes give off a slightly different kind of light.
By watching the plants constantly using a camera attached to a cheap computer, the scientists set up a system that can send a warning email if chemicals from explosives are detected in the water.
The researchers say it takes about 10 minutes for the plants to react to the chemicals. The computer the scientists used is about the size of a playing card. They say that in the future, their system could even use a cellphone with its camera changed slightly.
Detecting chemicals used in bombs is just one of the many uses the researchers are exploring. The scientists believe that in the future, such a system could give farmers detailed information about the health of the land and water on their farms.
【1】Why is the report mentioned in the first paragraph?
A．To tell a joke made by MIT scientists.
B．To introduce the health benefits of spinach.
C．To criticize misleading news on social media.
D．To bring up the topic of a scientific experiment.
【2】What is the function carton nanotubes in spinach leaves?
A．To supply energy to spinach.
B．To detect spinach’s lack of water.
C．To measure CO2 absorbed by spinach.
D．To make spinach shine in a special way.
【3】What do the scientists expect of their system?
A．It will take effect immediately.
B．It will be applied to agriculture.
C．It will be expanded to other plants.
D．It will use a playing card-sized cellphone.
【4】What is the text mainly about?
A．Scientists teach spinach to send work emails.
B．Scientists create spinach that can test for bombs.
C．Scientists change the composition of spinach we eat.
D．Scientists use nanotechnology to boost spinach production.
27、What’s really green?
Most of us are aware that we must protect the environment. But recently, some “green truths” have turned out only half true, or even completely false. Here are some common ones.
Paper shopping bags are better than plastic ones.
Plastic bags cause litter, bring dangers to wild animals and take long to break down. So people think paper bags are better. However, making a paper bag uses four times as much energy as making a plastic bag and three times the amount of water, besides producing more greenhouse gases.
Actually, neither are environment-friendly. So, take a reusable bag with you when shopping.
Running your car air conditioning burns more gas.
Running your car air conditioning (A/C) will affect your gas mileage, costing you more money and producing more pollution. However, if you want to save gas by turning off the A/C and rolling down your windows, you have to drive at low speed. At high speed, the aerodynamic drag (空气阻力) caused by open windows will actually cost you more gas. It does help save some gas if you turn off your A/C a few minutes before arriving at your destination.
It’s better to take a shower than a bath.
It depends on your shower time and size of your bath. If you spend over eight minutes in a shower, you’ll use as much water as in a bath. Therefore, the key is to keep your shower time as short as possible.
When you turn off a device, it stops using power.
When we turn off a device like television, it goes into stand-by mode. However, devices in this mode still use power. To ensure your device is truly off, just remove the plug (插头).
【1】What is the problem of paper shopping bags?
A．They are a threat to wild animals.
B．They cause litter.
C．They are energy-consuming to produce.
D．They can’t break down.
【2】Which of the following does the author agree with?
A．Bring a plastic bag when shopping.
B．Have a quick shower.
C．Drive at high speed with open windows.
D．Keep your television in stand-by mode.
【3】What’s the purpose of the text?
A．To clear up some misunderstandings.
B．To persuade people to live green.
C．To inform people of some green products.
D．To evidence some green truths.
28、The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colors in meats and other food additives (添加剂) caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin (青霉素) to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar things are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
【1】According to this passage, we can know _____.
A. perhaps most kinds of cancer are related to what people eat

C. cancer was discovered in 1945
D. science has made food unfit to eat
【2】Things that are used to keep colors in meats are _____.
A. harmful B. useless C. helpless D. dangerous
【3】People use additives _____.
A. to make food more unfit to eat
B. to cause cancer
C. to change the color of the food
D. to take off the diseases of the food
【4】Which of the following is NOT true?
A. Some wrappings of food are harmful.
B. Farmers try to make more money on the market by fattening their animals.
C. "The practice continues" means "things are still going on like that".
D. We needn't take care of what we eat.
