TOKYO, JAPAN-- What do you do when you see a cockroach? Do you hit it with a newspaper? Do you step on it?

When researchers at Tokyo University see a cockroach,they take the remote control and make the cockroach turn around,run left or right,or go forward.These scientists are changing the cockroaches into robots. Each cockroach has a very small pack that has a microprocessor in it. Then researchers can send signals from the remote control to the packet. The signals control the movements of the cockroaches.

Why does anyone want to control a cockroach? "Insects can do many things that people can't,” says Isao Shimoyama, head of robot research at Tokyo University. In a few years, he says, these robot insects will carry very small cameras. They will be able to move through earthquake rubble to look for people or move under door to find information about someone.

This may seem strange, but the Japanese government thinks the research is very important. The government is giving the scientists $5 million for this research.

First, the researchers breed hundreds of cockroaches. They use only the American cockroach because it is bigger and stronger than other cockroaches. Then they choose the best cockroaches and remove their wings and antennae. They put small packets where the antennae were. The packets weigh about three grams, or about two times the weight of the cockroaches themselves. “Cockroaches are very strong,” says Ralph Holzer,who is a researcher at Tokyo University. "They can lift 20 times their own weight.”

With a remote control, the scientists send signals to the packets. When a cockroach gets the signal, it moves. The problem is that the cockroaches don' t always move in the right direction.

1.The scientists are changing the cockroaches into robots because________.

A.they want cockroaches to take photos of the earthquakes

B.they want to send signals to the packets on the cockroaches

C.they want to control the movements of cockroaches

D.they want cockroaches to do things people can't

2.What can cockroaches do to help people in the future?

A.They can turn around, run left or right or go around.

B.They can help people to carry very small cameras.

C.They can search for those people in rubble after an earthquake.

D.They can breed hundreds of cockroaches.

3.Scientists control cockroaches movements ________.

A.by removing their wings B.by using very small cameras

C.by removing their antennae D.by sending signals from the remote control

4.What problem do the researchers meet with?

A.The cockroaches sometimes don't move.

B.The cockroaches sometimes move in the wrong direction.

C.The cockroaches are too big to move through earthquake rubble.

D.The cockroaches often lift 20 times their own weight.

5.What's the object of this article?

A.The cockroaches B.The signals

C.The cockroach robot D.The researchers

Recent development has made possible machines that print, cook, and serve a large number of foods. And the industry(产业) isn’t stopping there.

Food production

With a 3D printer, a cook can print complicated(复杂的) chocolate sculptures and beautiful pieces for decoration on a wedding cake. Not everybody can do that — it takes years of experience, but a printer makes it easy. A restaurant in Spain uses a Food printer to “re-create forms and pieces” of food that are “exactly the same,” freeing cooks to finish other tasks. In another restaurant, all of the dishes and desserts it serves are 3D-printed, rather than farm to table.

Sustainability(可持续性）

The world’s population(人口) is expected to grow to 9.6 billion by 2050, and some experts estimate (估计) that food production will need to be raised by 50 percent to keep present levels(水平). Sustainability is becoming a necessity. 3D food printing could probably help solve the problem. Some experts believe printers could use hydrocolloids (水解胶体) from rich renewable materials(原料) like algae and grass to replace(代替) the ingredients(烹饪原料). 3D printing can reduce fuel use and emissions(排放). The stores of the future might store "food" that lasts for years, freeing up shelf space and reducing transportation and storage requirements.

Nutrition(营养)

Future 3D food printers could make food healthier. Hod Lipson, a professor at Columbia University, said, “Food printing could allow customers(消费者) to print food with customized(定制的) nutritional content, like vitamins. So instead of eating a piece of yesterday’s bread from the supermarket, you’d eat something baked just for you on demand(要求).”

Challenges

Though there are great developments in 3D food printing, the industry has many challenges to overcome. Most ingredients must be changed to a dry powder(粉末) before a printer can use them, and the printing process takes a lot of time, because ingredients interact (相互作用)with each other in very complex ways. Besides, most of the 3D food printers now use only dry ingredients, because meat and milk products may easily go bad. Some experts doubt about 3D food printers, believing they are more suitable for fast food restaurants than homes and high-end restaurants.

1.What advantage(好处) does 3D printing bring to food production?

A.It teaches cooks to create new dishes. B.It saves time and effort(努力) in cooking.

C.It improves the cooking conditions. D.It helps to decorate the restaurants.

2.What does the underlined word “raise” mean in paragraph 3?

A.募集 B.导致 C.培育 D.增加

3.According to Paragraph 4, 3D-printed food ________.

A.is easier for consumers to get B.can meet personal nutritional needs

C.is tastier than food in supermarkets D.can keep all the nutrition in raw(生的) materials

4.What is the main factor(因素) that prevents 3D food printing from spreading widely?

A.The printing process is not long. B.3D food printers are too expensive.

C.Food materials have to be dry. D.Some experts doubt 3D food printing.

5.What could be the best title of the passage?

A.3D Food Printing: Delicious New Technology B.A New Way to Improve 3D Food Printing

C.The Challenges for 3D Food Production D.3D Food Printing: From Farm to Table
