It is always a mystery about how the universe began, whether if and when it will end. Astronomers construct hypotheses called cosmological models that try to find the answer. There are two types of models: Big Bang and Steady State. However, through many observational evidences, the Big Bang theory can best explain the creation of the universe. The Big Bang model postulates that about 15 to 20 billion years ago, the universe violently exploded into being, in an event called the Big Bang. Before the Big Bang, all of the matter and radiation of our present universe were packed together in the primeval fireball--an extremely hot dense state from which the universe rapidly expanded.1 The Big Bang was the start of time and space. The matter and radiation of that early stage rapidly expanded and cooled. Several million years later, it condensed into galaxies. The universe has continued to expand, and the galaxies have continued moving away from each other ever since. Today the universe is still expanding, as astronomers have observed. The Steady State model says that the universe does not evolve or change in time. There was no beginning in the past, nor will there be change in the future. This model assumes the perfect cosmological principle. This principle says that the universe is the same everywhere on the large-scale; at all times.2 It maintains the same average density of matter forever. There are observational evidences found that can prove the Big Bang model is more reasonable than the Steady State model. First the redshifts of distant galaxies. Redshift is a Doppler effect which states that if a galaxy is moving away, the spectral line of that galaxy observed will have a shift to the red end. The faster the galaxy moves the more shifts it has. If the galaxy is moving closer, the spectral line will show a blue shift. If the galaxy is not moving, there is no shift at all. However, as astronomers observed, the more distance a galaxy is located from Earth, the more redshift it shows on the spectrum. This means the further a galaxy is, the faster it moves. Therefore, the universe is expanding, and the Big Bang model seems more reasonable than the Steady State model.

Although many people believe that cooking and eating at home has more advantages and pleasures than eating out at restaurants, it is almost obvious that it is a boring experience which lacks variety. To escape from the routine of cooking and eating at home, many people visit their favourite restaurants or, if they are feeling adventurous, they try an unfamiliar eating place. When you eat out, you have the chance to sample tasty dishes which are fully prepared by experienced chefs. You can try everything from spicy eastern dishes to traditional French and English cuisine. Eating out also gives you the chance to socialise with friends and to enjoy a relaxing meal without having to make any tiring preparations beforehand.

Everybody has been talking about detox recently. What is this detox? Even though for some people detox is a kind of spring cleaning they do at home to their bodies, detox is not a new recovery method or a program that people can employ during the weekend and go back to their normal life again. It is a process that our cells are especially used to and helps our bodies rejuvenate themselves. Just as antibiotics kill bacteria in the body, detox is a system that enables the cells to get the best nourishment and helps in the elimination of toxins from the body. The liver, which is responsible for the removal of the body’s toxins, turns toxins into harmless substances that can be discharged from the body as feces, urine, perspiration, breath, tears and other bodily fluids. These excretion channels should work properly for an effective toxin discharge. If toxins cannot be discharged from the body, they overload the lymph system and can destroy the immune system’s balance.
3. We can understand from the passage that ..............
A) detox should be carried out in health centers by doctors
B) detox happens on condition that excretion channels function efficiently
C) in order to discharge the toxins, we should drink a large amount of water
D) doctors recommend people to use certain chemicals to discharge the toxins from their bodies
E) detox may cause bacteria to penetrate into the human body

Women seem to be particularly vulnerable to depression during their reproductive years: Rates of the disorder are highest in females between the ages of 25 and 45. New data indicate that the incidence of depression in females rises after giving birth. In 2007 Patricia Dietz reported that 10.4% of 4,398 mothers had been depressed in the nine months following childbirth compared with 8.7% in the nine months before pregnancy and 6.9% during pregnancy. More than half of the women with post natal depression had also been depressed during or before pregnancy suggesting that a previous occurrence of depression may be the biggest risk factor for acquiring the illness postpartum depression. But the hormonal changes that occur in a new mother's body are also thought to contribute to postpartum depression. During pregnancy, a woman experiences a surge in blood levels of oestrogen and progesterone. Then, in the first 48 hours after childbirth, the amount of these two hormones falls suddenly, almost back to normal levels. This chemical instability could contribute to depression. Of course, hormonal flux does not fully explain postpartum depression. After all, this biochemical fluctuation occurs in all new mothers and yet only a relatively small proportion of them become depressed.
It is understood from the passage that one of the causes of postpartum depression could be —.
A) the hormonal changes that are similar to those in the absence of pregnancy
B) the sudden decrease in the amount of oestrogen and progesterone following childbirth
C) the chemical stability in the blood levels during the first 48 hours after childbirth
D) a biochemical fluctuation taking place before pregnancy begins
E) that some mothers are not psychologically ready
to care for a baby
In our solar system today there are over 30 000 asteroids flying around in all directions colliding with other asteroids and planets not caring about the destruction they might convey. Our planet Earth is caught right in the middle of all of this action and is liable to entire extinction of any life forms on the planet if a large enough asteroid crosses its path. Any one single asteroid has the possibility to erase thousands of years of history and wipe out the human race as we know it. Asteroids are large or small chunks of rock and metal flying around space up to speeds of 80 000 km/h. These chunks were believed to have formed millions of years ago during the 'big bang'. These rocks didn’t form any planets and were stuck floating around space on their own or in the gravitation of the asteroid belt. This belt is approximately 300 million miles from the Sun and it contains thousands of asteroids some being miles in diameter. Another theory of the formation of asteroids is that a planet between Mars and Jupiter once existed and after many years it exploded into thousands of pieces that are still revolving around the sun in the form of an asteroid belt. Other asteroids are formed when large meteors collide with large asteroids creating more small ones. These meteors can also collide with planets breaking off chunks of the crust into space. Ceres is believed to be the biggest asteroid that was in space at one point in time. Ceres was believed to be 600 miles wide making up 1/3 of the total mass of all asteroids. Ceres was the first asteroid discovered and was found in 1801.
45. It is inferred from the passage that____
A) the total mass of all asteroids in the solar system is much less than the mass of the Moon
B) originally perhaps only a few dozen asteroids existed
C) asteroids move out of the asteroid belt because heat from the Sun warms them unevenly
D) collisions or explosions are certain on the formation of any asteroid.
E) certain asteroids may be binary, or have satellites of their own.
