Every place offers the possible dangers for getting hurt, even staying at work. We may face dangers like walking into desks or chairs, receiving unexpected cuts from a paper knife and so on. Industrial jobs have similar and more dangers like getting body parts hurt by machines or falling from a height.
No one wants to get hurt. Some accidents are avoidable(可避免的). Most accidents happen because of common things seen every day—an open desk drawer, a chair pulled out too far, water on the floor and so on. We slowly get used to these things we see every day and never think about what they could possibly become in the future.
Think about the following to prevent dangers to yourself and others:
1. If there is something you see and know may become a danger for yourself or others, do something about it. Close a desk drawer, clean up or put a sign over the water, turn off the power before leaving, and so on.
2. Get extra persons’ help and support on a task that is too hard for a single person.
3. Study the situation and think what could possibly happen and change if necessary. Do it before something happens and you won’t have to say some day, “ I should have… How sorry I feel…”
To use an old phrase “ Safety is everyone’s duty.” Looking down on it could lead to being hurt. Keep the rule in mind every day “ Everyone wants to go home in the same condition the came to work in –or better.”

In Britain, the first day of the month of May is known as May Day. May day marks the end of the harsh(严酷的) winter months, welcomes the beginning of Summer, and optimistically looks forward to the bright and productive months. 
For their ancestors, largely in rural areas, it was a major annual festival and was celebrated(庆祝) through out the country, especially on the first day of May with music, dancing and games.
How was May Day Celebrated in the past?
May Day began early in the morning. People went out before sunrise in order to gather flowers and plants to make their houses and villages beautiful in the belief that the vegetation spirits(神灵) would bring good luck.
A traditional May Day dance is Maypole Dancing，On May Day, people used to cut down young trees and stick them in the ground in the village to mark the arrival of summer.People danced around the tree poles in celebration of the end of winter and the start of the fine weather that would allow planting to begin. Maypoles are still a part of some
village life and on May Day the villagers dance around it.
May Day celebrations have their origins(起源) in the Roman festival of Flora, goddess(女神) of fruit and flowers, which marked the beginning of summer. So the highlight of the day was the crowning(为…加冕) of the May Queen(女皇), the human replica (模型) of Flora. By tradition she took no part in the games or dancing, but sat like a queen in a flower-decked chair to watch her 'subjects'.
Ever since 1978, for the convenience of the general public, many May Day activities have now been moved to the new May Day holiday on the first Monday of the month. This Monday is a bank holiday, a day off school and work. There are more intereting celebrations on this day.In the old days, most people in Britain made their living by .

Imagine having an idea, drawing it on paper, bringing it to a store and seeing it turned into an object. This is now possible with the help of 3D printers. Such machines were once used just by universities and big companies, but now, stores with 3D printing services are appearing around the United States.
Bryan Jaycox and his wife opened The Build Shop LLC in Los Angeles two years ago. The Jaycoxs offer 3D printing classes and services for anyone who is interested.
“I think 3D printing is going to be huge. It’s going to have a huge influence on society as a whole.” says KiChong Tran, one of the students in a recent class. He plans to open a 3D printing business in Cambodia (柬埔寨).
3D printing services are coming into American people’s life. The UPS Store is a nationwide retailer (零售商) that provides copying and other services. The UPS Store recently put 3D printers in three of its independently-owned stores. Burke Jones owns one of the stores in San Diego.
“The demand has been amazing. There has been a lot of interest from people. It’s been much more than I would have imagined.”
The UPS Store plans to add 3D printers in three more stores.
For $11, someone used a 3D printer to produce two small plastic parts as part of a knuckle (指节) for a hand. He works for the company which is testing finger prosthetics (假肢). He says the same–day or next-day printing services will speed up testing of parts and get them to patients faster.
Staples, an American store, is selling 3D printers on its website for as low as about $1,300. As with any technology - experts expect the printing speed to increase and the price to go down.
Bryan Jaycox requires $15 an hour to print an object. He also sets the price depending on the size of the object and up to $50 an hour for design and labor services.
Mr Jaycox thinks that within five years, 3D printing technology could become more user friendly. But KiChong Tran says even today’s technology can make a difference in a developing country like Cambodia.
“With 3D printing you can give them tools, so they are responsible more for their own development and they learn skills beyond just like learning English and becoming a tour guide or something like that. You can actually create things that give value to the world.”
He says it’s not just Cambodia but anywhere where there is a 3D printer, it can turn a good idea into reality.What can 3D printers do according to the passage?
| A．Come up with an idea. |
| B．Draw on a piece of paper. |
| C．Help users to spend less money. |
| D．Turn an idea into a physical object. |
What does the underlined part mean in this passage?
| A．Make users’ life better. |
| B．Make friends with users. |
| C．Make 3D printers easier to use. |
| D．Use 3D printers to make money. |
What can we infer from the passage?
| A．3D printing is becoming popular in the world. |
| B．There is no 3D printing business in Cambodia. |
| C．The UPS Store is the biggest 3D printing company. |
| D．3D printing plays the most important role in daily life. |
What’s the passage mainly about?
| A．The future of 3D printing in the world. |
| B．The 3D printing business in Cambodia. |
| C．The development and growth of 3D printing business. |
| D．The 3D printing classes and services in different places. |
Seeing a volcano erupt (喷发) is a wonderful experience, and you can really feel the heat by climbing to the summit of Pacaya for a close-up view. There are guided tours every day up this highly active volcano from Antigua. Giving travelers a chance to see Mother Nature at her most powerful (强大的).
Pacaya is an easy drive from Antigua, a beautiful city with many colorful houses along its old streets that are turned into art-works during its Holy Week festival. No matter when you come to Antigua, you won’t miss the Pacaya-tour companies.
But climbing Pacaya is no easy job: it is 2,560 metres high and reaching the summit takes two to three hours of seemingly one-step-forward and two-step-back movements. As you climb, you hear the sounds of eruptions high above. Smoke, hot remains from recent eruptions begin to line the path as you near the active summit: the McKenney Cone (火山锥). Just as though you were going to walk over to the edge of the cone, the road turns to the left and up to the safety of the old, inactive summit.
Many tours are timed so that you arrive at the cone of the volcano in plenty of time for sunset and the full scene of the erupting red lava (熔岩) in the darkening sky. On a good day the view from the summit is really exciting. The active mouth boils, sending red lava over its sides, and once in a while shoots hot streams up to 100 metres into the air. There is a strong bad smell in the air even if you take care to be upwind of the cone. As evening turns deeper into the night, the burning lava quietly falls down the side of the volcano. For you, too, it is time to get down.
| A．get down the mountain in time when night falls |
| B．avoid the smell from the upwind direction of the cone |
| C．enjoy the fantastic eruption against the darkening sky |
| D．appreciate the beauty of the 2,560-metre-high mountain |
| A．remained, cooled rocks along the path |
| B．loud sound and terrible smell in the air |
| C．the most exciting happening in a place |
| D．the top point of a mountain or hill |
| A．To have more tourists come to Pacaya. |
| B．To describe the beauty of Pacaya. |
| C．To introduce guided tours to Pacaya. |
| D．To explain the power of nature at Pacaya. |
Which part of the world has the most nearsighted students? Just look around you–it’s East Asia. Nine in ten school leavers in major East Asian cities are nearsighted, according to the BBC. Experts say books and video games are not to blame. East Asian students, they say, aren’t getting enough sunlight.
People become nearsighted because their eyeballs grow out of shape and light entering their eyes cannot focus correctly. The body can produce a chemical called dopamine (多巴胺) to stop eyeballs from changing shape. And guess what scientists have just discovered? Sunlight can help our bodies produce more dopamine, reported AFP.
According to the study, primary school students in Singapore spend only 30 minutes outdoors every day; in Australia, by contrast, kids spend about three hours a day outside. As a result, fewer children in Australia are nearsighted–only 10 percent, compared with 90 percent in Singapore.
“Children in East Asia basically go to school... go home and stay inside. They study and they watch television,” Ian Morgan of the Australian National University told AFP.
But being a bookworm or a couch potato does not directly harm the eyes, added Morgan. “As long as they get outside, it doesn’t seem to matter how much study they do,” he explained. “There are some kids who study hard and get outside and play hard and they are generally fine. The ones who are at major risk are the ones who study hard and don’t get outside. As a result of massive (巨大的) educational pressures and the construction (构成) of a child’s day, the amount of time they spend outside in bright light is minimized.”
Experts suggest children should stay outside for two to three hours every day. This can include time spent in the playground and walking to and from school. Which of the word has the similar meaning as the underlined phrase “nine in ten”?
| A．many | B．few | C．some | D．most |
What is the main reason for the large number of nearsighted students in East Asia, according to scientists?
| A．Too much reading or gaming. | B．Lack（缺少）of sunlight. |
| C．Genetic reasons. | D．Lack of exercise. |
What can we conclude from Paragraph 2?
| A．Dopamine is a chemical that causes eyeballs to grow out of shape. |
| B．Dopamine can stop light entering the eyes from focusing correctly. |
| C．Spending time in the sun can make the loss of dopamine in the body. |
| D．The more dopamine a person has in their body, the better eyesight he or she has. |
According to Morgan, what kind of people are most likely to suffer from nearsightedness?
| A．Those who like watching TV. |
| B．Those who take exercise regularly. |
| C．Those who study hard and play hard outdoors. |
| D．Those who stay indoors studying all day |
The air plant has wonderful and amazing features. It takes in moisture(水汽)from the air through its leaves．Although it is seen growing on another object or plant to support itself.
To prevent the roots from being too wet，avoid(避免) planting it in soil. Keep the roots in a well—ventilated(通风良好的)environment. Air plants can grow well hanging from fishing lines. They can also be hung from seashells, teacups or even on wood.
Water the air plant once in a while. Simply let the water fall from the roots. The roots will take in the water for the air plant. The air plant can live between 0℃° and 51 ℃. It does not need to be in the light all the time. However, sunlight(morning and evening only)helps it to reproduce(繁殖)faster. When it flowers，it turns a colorful pink, red or orange．At most 8 young plants can grow from the air plant．When these grow to half the size of the parent plant, simply pull them away gently from the parent plant and plant them in another place．
The lifespan of an air plant depends on the care it gets and the environment it is placed in. Generally, all air plant can live for many years.
Because they are so beautiful and easy to take care of, air plants are excellent as birthday gifts or housewarming gifts.The air plant takes in moisture from ______.
| A．other plants | B．the air |

Bananas don’t grow on trees. They grow on a stalk that looks just a little like a stalk of corn. The stalk is soft enough to be cut with a knife. 
It takes about a year before bananas are ready to be picked. Some are as small as fingers. Others are as long as men’s arms. Some banana plants grow as tall as a house – even taller!
Not all bananas are eaten as fruit. Some never get sweet, and they are cooked as a kind of vegetable.
People in most countries never see a banana until it reaches the store. But if you visited a country where it’s hot and rains a lot all the year, you might see a banana plantation, a large farm where bananas grow.
The tasty fruit doesn’t come from a seed but from a root planted deep in the ground. First a stalk pushes up into the air. The leaves grow. In the beginning the banana plant grows very fast – sometimes as much as the length of your feet in one night. Soon, sweet-smelling flowers come out, and when their flowers drop off, bananas begin to grow.
As they get bigger, bananas start turning up. It looks as if they’re growing upside down! Bananas are ready to eat when they turn soft and yellow. Bananas are picked long before this – when they’re hard and green. This is because bananas have to travel many miles before they arrive at a store. On trucks and boats and trains bananas travel all over the world. There are special boats just for bananas and special trains that keep them just cool enough so that they will get ripe while traveling. If bananas are picked when they are ripe (成熟的), they will spoil on the way.What’s the weather like in places where bananas grow?
| A．Dry and cold | B．Cold and wet | C．Wet and hot | D．Hot and dry |
The fruit of banana plants come from________.
| A．a stalk | B．a tree | C．a seed | D． a root |
