 The need for a surgical operation, especially an emergency operation, almost always comes as a severe shock to the patient and his family. Despite modern advances, most people still have an irrational fear of hospitals and anaesthetics. Patients do not often believe they really need surgery- cutting into a part of the body as opposed to treatment with drugs.
In the early year of the 20th century, there was little specialization in surgery. A good surgeon was capable of performing almost every operation that had been advised up to that time. Today the situation is different. Operations are now being carried out that were not even dreamed of fifty years ago. The heart can be safely opened and its valves repaired. Clogged blood vessels can be clean out, and broken ones mended and replaced. A lung, the whole stomach, or even part of the brain can be removed and still permit the patient to live a comfortable and satisfactory life. However, not every surgeon wants to, or is qualified to carry out every type of modern operation.
The scope of surgery has increase remarkably in the past decades. Its safety has increased, too. Deaths from most operations are about 20% of what they were in 1910 and surgery has been extended in many directions, for example, to certain types of birth defects in new born babies, and at the other end of the scale, to life-saving operation for the octogenarian. The hospital stay after surgery has been shortened to as little as a week for most major operations. Most patients are out of bed on the day after an operation and may be back at work in two or three weeks.
One of the most revolutionary areas of modern surgery is that of organ transplants. Until a few decades ago, no person, except an identical twins, was able to accept into his body the tissues of another person without reacting against them and eventually killing them. Recently, however, it has been discovered that with the use of X-rays and special drugs, it is possible to graft tissues from one person to another which will survive for periods of a year or more. Kidneys have been successfully transplanted between non-identical twins. Heart and lung transplants have also been reasonably successful.
“Spare parts” surgery, the simple routine replacement of all worn-out organs by new ones, is still a dream of the future but surgery is ready for such miracles. In the meantime, you can be happy if the doctors say to you: “Yes, I think it is possible to operate on you for this condition.”
Today, compared with 1910 _________.
A.20% fewer of all operation patients die 
B.20% of all operation patients recover
C.operation deaths have increased by 20% 
D.five times fewer patients die after being operated on

Read  the  following  passage  and  mark  the  letter A, B, C, or D on  your  answer  sheet  to  indicate  the correct   answer  to  each  of  the  questions   from   36  to  42.
American movies create myths about college life in the United States. These stories are entertaining, but they are not true. You have to look beyond Hollywood movies to understand what college is really like.
Thanks to the movies, many people believe that college students party and socialize more than they study. Movies almost never show students working hard in class or in the library. Instead, movies show them eating, talking, hanging out, or dancing to loud music at wild parties. While it is true that American students have the freedom to participate in activities, they also have academic responsibilities. In order to succeed, they have to attend classes and study hard.
Another movie myth is that athletics is the only important extracurricular activity. In fact, there is a wide variety of nonacademic activities on campus such as special clubs, service organizations, art, and theater programs. This variety allows students to choose what interests them. Even more important, after graduation, students’ résumés look better to employers if they list a few extracurricular activities.
Most students in the movies can easily afford higher education. If only this were true! While it is true that some American college students are wealthy, most are from families with moderate incomes. Up to 80% of them get some type of financial aid. Students from middle and lower-income families often work part-time throughout their college years. There is one thing that many college students have in common, but it is not something you will see in the movies. They have parents who think higher education is a priority, a necessary and important part of their children's lives.
Movies about college life usually have characters that are extreme in some way: super athletic, super intelligent, super wealthy, super glamorous, etc. Movies use these stereotypes, along with other myths of romance and adventure because audiences like going to movies that include these elements. Of course, real college students are not like movie characters at all.
So the next time you want a taste of the college experience, do not go to the movies. Look at some college websites or brochures instead. Take a walk around your local college campus. Visit a few classes. True, you may not be able to see the same people or exciting action you will see in the movies, but you can be sure that there are plenty of academic adventures going on all around you!

A.they are not allowed to work full-time

Read the passage carefully, then choose the correct answer.
There is one planet that still fascinates and teases scientists mainly because it doesn't have an atmosphere to obscure observation, yet it is not big enough for sufficiently accurate telescopic observation. The fact that it is also very close to the sun also makes it difficult for astronomers.
However, space telescopes have told us a lot more about Mercury. It is rather similar to Earth's moon and to Mars. There are mountainous areas dotted with craters and large valleys which are uncratered. The moon's valleys have fewer cracks and the ridges are smoother. Mercury's valleys are filled with volcanic rocks, similar to on the moon, yet there is no evidence of volcanoes, even extinct ones, on Mercury, as there is on the both Mars and the moon, and of course here on Earth.
So, scientists presume the valleys on Mercury were caused by different things, that is to say not by volcanoes, but by very large meteorites, which also caused the cracks in the terrain and left the ridges rough and uneven. More and better photos of Mercury are needed to prove what are at present at best only hypotheses.
What is true about Mercury but not true about the moon or Mars?
A.The valleys are filled with volcanic rocks.   
B.There are no volcanoes.
C.The valleys are uncratered       
D.There are hilly regions.
