Around 200 million years ago, the earth was 18 degrees warmer than it is now.　 That might be a bit hot for humans, but it was just right for the giant dinosaurs that wandered about the earth during the Mesozoic (中生代的) era. A new study found that planteating dinosaurs may have contributed to the warming of the earth­by releasing significant amounts of methane (甲烷)．

The study, published in science journal Current Biology, focused on sauropods, long­necked herbivores (食草动物) that munched (用力咀嚼) on the top of trees. They　 were the largest of the dinosaurs; food broke down in their　 stomachs for long periods of time.　 The researchers estimate that a sauropoda released 2,675 liters of methane per　 day—adding up to a large amount of the greenhouse gas　 being pumped from dinosaur's gut into the atmosphere.

Plant eaters naturally release methane as part of their　　 digestive process. The larger the animal, the more methane　 it produces. Methane, a greenhouse gas, traps heat and remains in the atmosphere for approximately 9­15 years,　 which warms the atmosphere.

Today,　 some　 animals,　 such　 as　 cattle,　 goats　 and　 sheep, produce large amounts of methane as a by­product　 to their food digestion. Methane is also released from human—influenced sources such as landfill, agricultural activities, coal mining and other industrial practices—which all contribute to today's climate change, according to the　 Environmental Protection Agency.

The researchers estimate that earth's sauropods would　 have produced about 520 million tons of methane per　 year—similar to the total amount of methane produced today by natural and man­made sources.　 However, the researchers warn that their numbers are estimates based on　 multiple assumptions about the digestive systems and populations of dinosaurs.

The author of the study David Wilkinson says the　 emission of methane from dinosaurs would have been just　 one of the causes of warm climate during the Mesozoic era.　 Other　 causes　 include　 gases　 produced　 from　 volcanoes,　 swamps, shallow seas and so on. Still, Wilkinson says，“　 The amount of methane from dinosaurs is large enough to　 have a measurable effect.”

1.Scientists think dinosaurs may have led to the global　　　 warming because ________.

A．they ate everything they found

B．they usually had a good appetite

C．they released a lot of methane

D. there were too many dinosaurs on earth

2.What do we know about dinosaurs from Paragraph 2?

A．Sauropods fed on plants.

B．Sauropods were of medium size.

C．Dinosaurs used to live on trees.

D．Dinosaurs digested food quickly.

3.Which　 of　 the　 following　 activities　 doesn't　 produce　　　 methane?

A．Coal is dug out by machine.

B．Trees and flowers are planted.

C．Goats digest grass under the tree.

D．Food is being processed in the factory.

4.How does the author make his writing reliable?

A．By listing some facts.

B．By making predictions.

C．By citing figures.

D．By using mind pictures.

5.David Wilkinson seems to believe that ________.

A．methane had little effects on the earth

B．many other factors contributed to warm climate

C．other causes for warm climate were worth considering

D．dinosaurs were mainly to blame for global warming

Scientists would like to place a huge mirror in space above the earth. It might be sixty miles wide. It would be used to catch the rays (光线) of the sun. It would direct the sun’s rays upon the earth as a child might do to make sunlight dance on the wall with a hand mirror.

Why do they want to do this? The sun’s rays could be helpful in many ways. They could light up cities by night. The warm rays could stop frosts (霜冻) which might come at night and hurt fruit crops. They could melt (融化) dangerous icebergs in the ocean. Perhaps they could change cloud movements and bring rain where it is needed.

1.The huge mirror would ______.

A．stand 60 miles in height (高度)             B．be 60 miles from side to side

C．cover 60 miles of the earth                D．be 60 miles above the earth

2.The mirror would be used to ______.

A．reflect (反射) sunlight                    B．absorb (吸收) sunlight

C．see what the earth looks like               D．see how clouds move

3.The strong light from the mirror could possibly ______.

A．hurt fruit crops                         B．set fire to cities

C．bring longer daytime                     D．shine through walls

4.The huge mirror is ______.

A．something in a story                     B．already made

C．just an idea                            D．to be made soon

In the future we might live somewhere other than Earth, like Mars. Some people ask how this will be possible. Well, Mars is in fact a lot the same as the earth. The days are almost the same as those on the earth. However, the two planets vary in temperature.

Since there is mostly carbon dioxide on Mars, it would be quite difficult for a human to just land on it. So, special types of homes and space suits have to be designed. The space suits should be almost like the ones astronauts use now, and except that they have to be warmer so that the astronauts can survive the cold temperatures. The space suits must also be able to withstand (承受) high pressure and potentially dangerous radiation that can kill.

The houses should be similar to our homes today with a slight difference. All of the houses and other buildings should be built inside a large dome (圆顶状物) or bubble. The domes should be made out of glass, and would also be able to prevent radiation from affecting the people inside. The domes will be connected to a machine (like plants which turn carbon dioxide into oxygen).

With Mars’ population growing, how would the people on its surface get fresh food and water? Just like humans use domes, they can also use domes to grow plants. However, the domes where the plants are grown must be built to expand. Once we upgrade the domes to a larger size then we can grow more food by cultivating (种植) more plants. To get the food or come in connect with other domes, there will be long narrow tunnels like roads that connect to each dome separating them by several doors so that the pressure in each dome can remain the same.

On Mars, so many other things are available to us. As humans, we can have access to rare and fairly expensive metals that aren’t very easy to get hold of on Earth, and a colony on Mars enhances (提高) our chances of finding these metals. So when someone here on Earth says that going to Mars is impossible, please tell them that they’ll never know it until they try and they may try very soon. After all it’s our future. Why not make it on Mars?

1.It is difficult for humans to live on Mars because of all the following EXCEPT _________.

A. too much radiation　　 B. cold temperature

C. lack of enough oxygen　　 D. lack of houses

2.One of the reasons why we are eager to explore Mars may be that _________.

A. we can find rare and expensive metals there easily

B. we’ll get too bored to live on the earth in the future

C. our technology will become much advanced

D. we want to know more about the unknown world

3.What is the author’s attitude towards living on Mars? _________.

A. Pessimistic　　 B. Uncertain　　 C. Optimistic　　 D. Opposed

Coming to the end of my assistantship in Barcelona, I start to think about what the future might hold.

It’s been seven months and a few days since I arrived here and things have changed so much in what some might call a short period of time. When I first arrived in Terrassa I was excited and nervous to start a new adventure in a country I love. The first few days seem so long ago now, trying to find a place to live, organizing my timetable with the schools, meeting new people.

However, a fortnight later, the excitement started to fade and I began to spend more than a few nights thinking about family and friends back home, wondering if I should be there with them. Everything started to change after meeting some new friends and spending good time with them, eating together and seeing new places as a group. I suppose we should never forget how important it is to have good people in your life, because they can make a difference.

Coming back to Terrassa after visiting home for Christmas felt like returning to a second home, to a place that was mine with people I cared about. Things got even busier and more people came into my life; new friends, romance and a whole lot of good food flowed by in what seems to have been weeks, not months.

Now, looking forward, there are some decisions to make. Should I return home to Scotland and move on with life there or try to extend my time here, perhaps make it something permanent? Experiencing other cultures or learning about the world is such an important thing to do if you have the means.

My advice from my experience so far is to travel and try new things whenever you get the opportunity. You may find somewhere you were always supposed to be.

1.Why did the author go to Barcelona?

A. To meet his curiosity. B. To conduct his work.

C. To begin a new adventure. D. Do experience a new culture.

2.When did the author begin to feel homesick?

A. As soon as he set foot on Terrassa.

B. When he was considering his future.

C. After a few weeks’ stay in Terrassa.

D. When he was trying to find a living place.

3.What is the author unsure about?

A. Where to spend his future life.

B. How to enjoy his life in Terrassa.

C. What to do to extend his time in Terrassa.

D. Whether to celebrate Christmas with locals.

4.What has the author learned from his experience?

A. Having a clear idea of oneself is important.

B. Traveling alone brings a great many benefits.

C. Learning about the world makes life more colorful.

D. Keeping an open mind toward new things is necessary.
