If you gaze（凝视）through a telescope at a distant galaxy（星系）, it may glow brightly with the light of hundreds of millions of stars. Despite（尽管，不顾） all that light, most scientists think that at the center of a big galaxy lies something very dark: a black hole. A black hole is a region of space with gravity so strong that nothing can escape, not even light.

Astronomers recently announced they had observed a faraway galaxy that may have at its center two black holes, very close together. Based on their observations, the stargazers suspect one of the black holes has more mass than the other. The more mass something has, the stronger its gravitational force, so a larger black hole has a stronger gravitational attraction. The smaller black hole orbits（作轨道运行） the larger black hole, just as the earth orbits the sun.

The biggest galaxies in the universe form when two smaller galaxies collide（碰撞）. If  two galaxies merge（合并）, then all of their stars start orbiting a common center. The black holes at the galaxies’ centers should come together, too. Galaxies are colliding all the time, so we should be able to find lots of black hole pairs. But that’s easier said than done—astronomers rarely find these in deep space.

To find a black hole is complicated. A black hole doesn’t produce any light, so how can you find one in space? Astronomers think when something (like dust) falls into a giant black hole, a jet of radiation, a form of energy, may stream away. If this radiation is strong enough, it forms a quasar（类星体）.

The Arizona astronomers looked at more than 17,000 quasars and finally found a galaxy that may have a double black hole at its heart. Though the finding of their research is still unconfirmed, and they may be mistaken, the truth will be revealed in the future.

63. Which of the following is TRUE about black holes?

A. A black hole is a region in galaxies with nothing in it, even a bunch of light.

B. Black holes are used by astronomers to study how quasars come into being.

C. When different galaxies meet in space, the black holes become bigger and bigger

D. Some scientists think there’s one black hole in a galaxy, but others think there’re two.

64. From the second paragraph we can infer that ________.

A. a larger black hole pushes a smaller black hole away

B. a larger black hole pulls a smaller black hole toward it

C. the places of black holes are fixed, so we can see them clearly

D. a smaller black hole moves around a larger one because of radiation

65. According to the passage, astronomers think that there should be many black hole pairs because____________.

A. a black hole can produce light

B. black holes can attract one another

C. different black hole pairs come into being with the meeting of galaxies.

D. a big black hole can usually be divided into two small black holes

A popular saying goes, “Sticks and stones may break my bones, but words will never hurt me.” However, that’s not really true. Words have the power to build us up or tear us down. It doesn’t matter if the words come from someone’s else or ourselves --- the positive and negative effects are just as lasting.

    We all talk to ourselves sometimes. We’re usually too embarrassed to admit it, though. In fact, we really shouldn’t be because more and more experts believe talking to ourselves out loud is a healthy habit.

    This “self-talk” helps us motivate ourselves, remember things, solve problems, and calm ourselves down. Be aware, though, that as much as 77% of self-talk tends to be negative. So in order to stay positive, we should only speak words of encouragement to ourselves. We should also be quick to give ourselves a pat on the back. The next time you finish a project, do well in a test, or finally clean your room, join me in saying “Good job!”

    Often, words come out of our mouths without us thinking about the effect they will have. But we should be aware that our words cause certain responses in others. For example, when returning an item to a store, we might use warm, friendly language during the exchange. And the clear will probably respond in a similar manner. Or harsh（刻薄的）and critical language will most likely cause the clerk to be defensive.

    Words possess power because of their lasting effect. Many of us regret something we once said. And we remember unkind words said to us! Before speaking, we should always ask ourselves: Is it loving? Is it needed? If what we want to say doesn’t pass this test, then it’s better left unsaid.

    Words possess power: both positive and negative. Those around us receive encouragement when we speak positively. We can offer hope, build self-esteem（自尊）and motivate others to do their best. Negative words destroy all those things. Will we use our words to hurt or to heal? The choice is ours.

The main idea of the first paragraph is that ________.

A. not sticks and stones but words will hurt us 

B. inspiring words give us confidence

C. negative words may let us down

D. words have a lasting effect on us

There is no sense for us to feel embarrassed when we talk to ourselves because _______

A. almost everybody has the habit of talking to themselves

B. we can benefit from talking to ourselves

C. talking to ourselves always gives us courage

D. it does no harm to have “self-talk” when we are alone

The underlined part in the third paragraph means that we should also timely _______

A. praise ourselves                                                         B. remind ourselves

C. make ourselves relaxed                                              D. give ourselves amusement

The author would probably hold the view that ___________

A. encouraging words are sure to lead to kind offers  

B. negative words may stimulate us to make more progress

C. people tend to remember friendly words

D. it is better to think twice before talking to others

A few years ago, when I was still in high school, I met a wonderful and warm teacher. At that time in my life, there were many changes to adjust to, apart from the usual teenage troubles. My parents had divorced, so my elder brother and I had chosen to stay with my dad. Due to the fact that he was keeping the house, we didn’t have to move.

During this time, my teacher took a special interest in me. Being my English teacher, she encouraged my mind to travel to creativity I had long given up. She brought me out of the shell I built.

She became my mother, my older sister, my friend and my teacher. The one thing she couldn’t do though was to make me more girly as growing up with only my dad and brother made me a real tomboy.

Sometimes, I would be really immature（不成熟的）, especially if she was scoring me less than others on purpose. She knew I could do better than what I was handing in and so pushed me to extend further than limits.

When I finished school and then after college I was about to leave my hometowns she gifted me a watch that every second, with my pulse, should remind me of the one person who will forever wait and love me without reservation.

Time has passed and our friendship is distant, but in my heart, soul and mind, she is the closest I ever got.

If you ask people to name the one person who had the greatest effect on the English language,you will get answers like “Shakespeare”,“Samuel Johnson”and“Webster”,but none of these men had any effect at all compared to a man who didn't even speak English—William the Conqueror.

Before 1066,in the land we now call Great Britain lived peoples belonging to two major language groups.In the west?central region lived the Welsh,who spoke a Celtic language,and in the north lived the Scots,whose language,though not the same as Welsh, was also Celtic.In the rest of the country lived the Saxons,actually a mixture of Anglos,Saxons,and other Germanic and Nordic peoples,who spoke what we now call Anglo?Saxon(or Old English),a Germanic language.If this state of affairs had lasted,English today would be close to German.

But this state of affairs did not last.In 1066 the Normans led by William defeated the Saxons and began their rule over England.For about a century,French became the official language of England while Old English became the language of peasants. As a result,English words of politics and the law come from French rather than German.In some cases,modern English even shows a distinction (区别) between upper class  French and lower?class Anglo?Saxon in its words. We even have different words for some foods,meat in particular,depending on whether it is still out in the fields or at home ready to be cooked,which shows the fact that the Saxon peasants were doing the farming,while the upper?class Normans were doing most of the eating.

When Americans visit Europe for the first time,they usually find Germany more“foreign” than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man's ambition.

If you walk slowly though downtown Helsinki（赫尔辛基）during the day, taking in the splendid 19th century buildings, white boats and noise of passing trams（有轨电车）, you will start to understand why it is called a city of two colors: white and blue.

The sea is always present in Helsinki. When you take a walk over the great open space of the central square, you will hear seabirds creaming. When over the great open space of the central square, you will hear seabirds creaming. When you take the tram, suddenly and unexpectedly, you are faced with a calm, shining blue sea. You may notice that people in Helsinki do not rush about as in other cities. Instead, they walk along the roads, politely letting other people by.

A usual way to see Helsinki for the first time is to start out by the boats. You will walk by the elderly women selling fish and vegetables in the market square and find yourself in front of a beautiful park. You may enjoy a pleasant walk in the park for a few hours and then take the tram. Trams are the perfect way to get around in Helsinki. Watching the old houses, parks, theatres, churches, shops, restaurants and people in the streets, you may have a slightly sad film feeling to it.

The pale summer nights are another wonder in the city. Following the waterfront （滨水区）of the city after sunset, you couldn’t help stopping and listening to the sweet silence, interrupted only by the screaming seabirds and leaving fishing boats.

However, in some way. Helsinki is also the most modern city in northern Europe. You will surely want to visit the white Glass Palace, the modern art museum, and all those extremely popular cafes and design stores.

Helsinki is called a city of two colors mainly because of the colors of its          ,
