Many of us are interested in time travel and shuttling back and forth (来回地) to the past or the future. Who wouldn’t be enthralled by returning to the past or seeing the future? But time travel seems to be possible onl
y in our imagination or in science fiction (科幻小说).
Science fiction is a world where impos
sible things can become possible and that’s why most of us like it. But science fiction is not entirely fiction since it is based on science theories (理论). Time travel, for instance, is a theme used by sci-fi writers. Readers may sometimes think writers have first-hand experience of it. I have collected some of the popular ways in which time travel is made possible in science fiction:
● Through the wormhole — A wormhole is a path between points in space-time. According to Einstein, an object can pass through a wormhole if it can travel at the speed of light. An example of a wormhole is described in Riddle of the Red Bible.
● Through a black hole — A black hole is a vacuum (真空) in space where light cannot even escape or pass through. In some sci-fi movies, like Star Trek, black holes became the means to travel through time.
● Through time machines — In science fiction, time machines are vehicles that can travel faster than light. It can be a strange vehicle like the TARDIS in Doctor Who or a special car like the one used in Back to the Future. But these special vehicles would need a wormhole to travel to the past or the future.
● Through parallel universe (平行宇宙) — Another popular way to travel through time is to be able to get into a parallel universe where one can go back to a point in time and see a different reality.
Though we know time travel may not be possible, it is still an entertaining subject and a heated topic for most of us. And in science fiction, where reality is always in the imagination, time does not really matter.

Many of us spend a great deal of time and energy trying to prove that we are right and others are wrong. Many people believe that it’s their job to36others how their positions, statements and points of view are 37 and that in doing so, the person they are correcting is going to somehow 38 it, or at least learn something. Wrong！
Think about it. Have you ever been 39 by someone and said to him, “Thank you so much for showing me that I’m wrong and you’re right.” Or has anyone you know ever 40 you when you corrected him, or made yourself “right” at his 41? Of course not. The truth is, all of us 42to be corrected. We all want our position to be 43 and understood by others. Being listened to and heard is one of the greatest 44 of the human heart. And those who learn to 45 are the most loved and respected. Those who are in the 46 of correcting others are often hated and 47.
A wonderful way of becoming more peaceful and loving is to practice 48 others the joy of being right--- give them the glory. 49correcting. When someone says, “I really feel it’s important to…” rather than 50 and saying, “No, it’s more important to…” , simply let it go and allow his statement to 51. The people in your life will become less defensive and more 52. They will appreciate you more than you could ever have 53 possible. You’ll discover the joy of joining in and seeing other people’s 54, which is far more rewarding than a battle of egos（自我意识）. Starting today, and let others be “55 ” most of the time.

Many of us love July because it’s the month when nature’s berries and stone fruits are in abundance. These colourful and sweet jewels form British Columbia’s fields are little powerhouses of nutritional protection.
Of the common berries, strawberries are highest in vitamin C, although, because of their seeds, raspberries contain a little more protein (蛋白质), iron and zinc (not that fruits have much protein). Blueberries are particularly high in antioxidants (抗氧化物质). The yellow and orange stone fruits such as peaches are high in the carotenoids we turn into vitamin A and which are antioxidants. As for cherries (樱桃), they are so delicious who cares? However, they are rich in vitamin C.
When combined with berries of slices of other fruits, frozen bananas make an excellent base for thick, cooling fruit shakes and low fat “ice cream”. For this purpose, select ripe bananas for freezing as they are much sweeter. Remove the skin and place them in plastic bags or containers and freeze. If you like, a squeeze of fresh lemon juice on the bananas will prevent them turning brown. Frozen bananas will last several weeks, depending on their ripeness and the temperature of the freezer.
If you have a juicer, you can simply feed in frozen bananas and some berries or sliced fruit. Out comes a “soft-serve” creamy dessert, to be eaten right away. This makes a fun activity for a children’s party; they love feeding the fruit and frozen bananas into the top of the machine and watching the ice cream come out below.
1.What does the author seem to like about cherries?
A. They contain protein. B. They are high in vitamin A.
C. They have a pleasant taste. D. They are rich in antioxidants.

C. To speed up their ripening. D. To improve their nutrition.
3.What is “a juicer” in the last paragraph?
A. A dessert. B. A drink.
C. A container. D. A machine.
4.From which is the text probably taken?
A. A biology textbook. B. A health magazine.

Many of our favorite travel destinations are in danger of being changed badly by increased temperatures and rising seas. The following are some of the places that may be in danger and some that are already experiencing the effects of global warming.
The Everglades, Florida: Perhaps no region of the country is as unprotected to climate change as Florida. Even a slight increase in temperature and water level could devastate popular destinations like the Everglades, Miami Beach and the Keys.
Australia’s Great Barrier Reef: One of the most impressive natural habitats in the world, the Great Barrier Reef could be killed by increased water temperatures and the resulting coral bleaching (漂白法). Australia is particularly easily damaged by global warming because of its large number of fragile (脆弱的) ecosystems, uncertain water sources and a large group of people gathering on the coast.
Dalian, China: Fast-growing China, shown here during a heat wave last year, is opening about one coal factory every day this year. Along with the U.S., China is one of the world's leading contributors to the greenhouse gases , which can lead to the increase in the Earth's temperature.
Venice, Italy: No stranger to flooding, Venice has invested $4.5 billion in a floodgate system that is due to open in 2012. But the frequent changing ocean levels have made people question the floodgates' ability to hold out the rising waters.
London, England: Designed to protect London from storms and extremely high tides, the Thames Barrier was opened in 1984. Some analysts fear that rising oceans will create conditions beyond the capabilities the barrier was designed to meet.
1.The word “devastate” in paragraph 2 means “_____________”.
A. protect B. destroy C. swallow D. enlarge
2.What can endanger Great Barrier Reef directly?
A. Fragile ecosystem

Kiwis are unique in a lot of interesting ways. They have many characteristics that are not found in any other bird.
It ia assumed that the kiwi's ancestor was able to fly and reached New Zealand. Once on the island, it lost its ability to fly and eventually became the kiwi known today. Kiwis have feathers that look like hair and very strong and muscular legs. They rule the ground instead of the air. They can smell very well, Kiwis are quite shy and usually only come out at night. Kiwi can live a long time, between 25 and 50 years.
A female carries a huge egg for its body size. The kiwi is about the same size as a chicken but its egg is actually six times as large as a chicken’s egg. The reason for this is that the kiwi doesn’t have to fly so there aren't any limits on its weight. The female has to eat three times as much as usual to help the egg develop. Right before the egg is laid she can't eat anything because the egg presses against her stomach, leaving no room for food.
All kiwi species are endangered. On average, twenty-seven die each week. They have been affected most by deforestation and invasive mammals. Before humans came to New Zealand, the only mammals on the island were bats and seals.The kiwi never had to worry about predators before, but now since it cannot fly, and lays its eggs on the ground, it is pretty defenseless against invasive mammals such as rats and stoats. Stoats kill a lot of the chicks, while dogs kill a lot of adult birds, usually by accident, because they are quite delicate (易碎的).
1.Which is kiwi’s unique characteristic?
A.They can’t fly with no wings.
B.They can live more than 50 years,
C.They rule the air instead of the ground.
D.They seldom or never come out in the daytime.
2.Why does a female kiwi carry a huge egg?
A.It eats three times as much as usual.
B.I focuses too much on developing its egg.
C.Body weight will grow without limit for a flightless bird.
D.The egg presses against her stomach.
3.Which kind of mammal does no harm to kiwis?
A.Bats. B.Rats.
C.Stoats. D.Dogs.
4.Which is a suitable tile for the passage?
A.Endangered kiwi species B.Kiwis — unique birds
C.Get close to the bird world D.Why can’t kiwis fly?

If you are travelling in Britain, besides so many world-class things to see and do in London, planning a day trip away from it can also be worthwhile.
Stonehenge
Stonehenge consists of a group of huge standing stones. The 5,000-year-old stones are one of the world’s biggest mysteries that no one has figured out yet. While exploring Stonehenge, you can imagine wildly and decide for yourself how the stones came to be there and why. Although you can’t touch the stones, you can walk among them and feel the changes of seasons.
Windsor
Most people visit Windsor to see Windsor Castle, where the Queen spends most of her time. The castle itself could keep you busy for days. The best way to appreciate Windsor Castle is to approach via the Long Walk, a straight road where there are no cars, but you might see some deer.
Oxford
Oxford is best known for its world-famous university. The large student population keeps the atmosphere young and fresh, though there’s no shortage of history if you want it. 30 colleges make up the university itself. A tour of the colleges is a must—Harry Potter fans will recognize various locations used in the movies.
Bath
Founded by the Romans, who used the area’s springs to create a spa retreat（水疗中心）, Bath’s now the best tourist attraction of Southwest England. Visitors never miss the Roman Bath Complex, which is divided into four main parts—the Bath House, the Sacred Spring, the Roman Temple and the museum, which displays fascinating finds from the historical ruins of the city.
