The transition of digital photography from the privilege of rich people to an ordinary home appliance has caused some problems. That is the reason a modern man has a set of questions concerning digital cameras. The basic problem in choosing a digital camera is the (guarantee) that the device you are purchasing will “grow old” in a couple of months due to constant improvements and developments of technology. The only factor that may delay this process of “growing old” is purchasing a device with the price twice or three times higher than the average market price for a digital camera at the moment. If a person chooses a digital camera, there are several criteria of a great priority he needs to keep in mind: the price and the image resolution of the camera, the capacity of the memory card, the presence of an LCD display, the interface of the device and (its) weight and size.
    The price of digital camera (depends on) its quality factors. The resolution of a digital camera or the “size of a digital image, is measured in pixels which are photosensitive elements. It is common knowledge that the bigger the amount of pixels in the camera properties is, the better it is. Therefore, if a high- detailed photo is required, the usage of the zoom on a digital camera with low resolution will not give the desired result. In this case, a person choosing a digital camera needs to exactly know what it will be used for and to choose it according to its future destination. It is necessary to mention that the resolution of 640x 480 is the lowest resolution any customer should be orientated to. It is the minimal resolution with which the purchase of a digital camera still remains reasonable.
    The lens of the camera or the zoom properties allows saving a lot on the price of the device but hits the quality of the pictures. The memory card is a very important issue, too. It is much better to choose a good camera with a small memory capacity than an average digital camera with a larger memory capacity. The presence of an LCD display is no longer a wish. It is a requirement for any digital camera. It allows people to check the future image, to anticipate it and to delete bad images and therefore to save space.

Question 36: What is the best title for this passage?
A. How to Choose a Digital Camera
B. The Transition of Digital Photography
C. Problems in Purchasing a Camera
D. Elements of a Digital Camera
Question 37: In the first paragraph, the word “guarantee” is closest in meaning to_______.

Question 38: What does the word “its” in paragraph 1 refers to_____.
A. the memory card   B. the camera   C. the display    D. the price
Question 39: In the second paragraph, the phrase “depends on” is closest in meaning to______.
A. is decided by    B. is created by    C. consists of    D. makes up
Question 40: According to paragraph 2, when we are talking about the resolution of a digital camera, all of the following are what we should be aware of EXCEPT_______.
A. the future destination of the camera
B. the lowest resolution any customer should be orientated to
C. the size and weight of the camera
D. The purpose the camera will be used for
Question 41: What can we infer from the passage?
A. The larger the capacity of the memory card is, the better the camera is.
B. It is not so necessary to pay attention to the presence of an LCD display.
C. The lens of the camera is useless.

A. A camera with a much higher price than the average market price.
B. A camera with minimal resolution but still sounds reasonable to purchase.
C. An average camera with a large memory capacity.
D. An excellent camera with a small memory capacity.

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.

Animation traditionally is done by hand-drawing or painting successive frame of an object, each slightly different than the proceeding frame. In computer animation, although the computer may be the one to draw the different frames, in most cases the artist will draw the beginning and ending frames and the computer will produce the drawings between the first and the last drawing. This is generally referred to as computer-assisted animation, because the computer is more of a helper than an originator.

In full computer animation, complex mathematical formulas are used to produce the final sequences of pictures. These formulas operate on extensive databases of numbers that defines the objects in the pictures as they exist in mathematical space. The database consists of endpoints, and color and intensity information. Highly trained professionals are needed to produce such effects because animation that obtains high degrees of realism involves computer techniques from three-dimensional transformation, shading, and curvatures.

High-tech computer animation for film involves very expensive computer systems along with special color terminals or frame buffers. The frame buffer is nothing more than a giant image memory for viewing a single frame. It temporarily holds the image for display on the screen.

A camera can be used to film directly from the computer’s display screen, but for the highest quality images possible, expensive film recorders are used. The computer computers the positions and colors for the figures in the picture, and sends this information to the recorder, which captures it on film. Sometimes, however, the images are stored on a large magnetic disk before being sent to the recorder. Once this process is completed, it is replaced for the next frame. When the entire sequence has been recorded on the film, the film must be developed before the animation can be viewed. If the entire sequence does not seem right, the motions must be corrected, recomputed, redisplayed, and rerecorded. This approach can be very expensive and time – consuming. Often, computer-animation companies first do motion tests with simple computer-generated line drawings before selling their computers to the task of calculating the high-resolution, realistic-looking images.

Question. According to the passage, the positions and colors of the figures in high-tech animation are determined by _________

A. drawing several versions

B. enlarging one frame at a lime

C. analyzing the sequence from different angles

D. using computer calculations

Read the following passage and mark the letter A, B, C or D to indicate the correct answer to each of the questions.

The poaching crisis wiping out Africa's elephants is costing the continent's economies millions in lost tourism revenue, according to a new study. Researchers looked at visitor and elephant data across 25 countries, and modeled financial losses from fewer visitors in protected areas due to the illegal wildlife trade, which has caused elephant numbers to plummet by more than 100,000 in the last decade. (A)

The study team combined visitor numbers across 164 protected areas in 25 countries in forest and savannah elephants, and elephant population data from 2009 to 2013, to reach a “per elephant" value in terms of tourism income.

They concluded that Africa was most likely losing $26m in tourism revenue a year. (B) Around $9m of that is lost from tourists' direct spending, such as staying at hotels and buying crafts, with the rest through indirect value in the economy such as farmers and other suppliers supporting the tourist industry.

The study, published in the journal Nature Communications, found that in most cases the revenue losses were higher than paying for stronger anti-poaching measures to keep elephant populations stable. (C) Dr. Robin Naidoo, the paper's lead author and , senior conservation wildlife scientist at WWF and his team found. In the case of central Africa's forest elephants, which are harder for tourists to see and therefore attract fewer visitors, the costs of protecting them exceed the benefits from tourism. Demand from south-east Asia has seen the price of ivory triple since 2009 and it is estimated that one elephant is killed every 15 minutes. (D) Corruption, a lack of resources, and, most importantly, increasingly sophisticated poachers have hamstrung African countries' efforts to stem the trade.

Naidoo said that the research was not suggesting economic issues should be the only consideration when protecting elephants, but framing the poaching crisis as a financial one could motivate African governments and communities.

“It gives an additional reason for some groups of people, who may not necessarily be motivated by intrinsic reasons for conversation, to engage with biodiversity conservation. It makes it clear to them that it's not just in the best interests of the world to conserve this stuff, but tangible reasons for a whole different group," he said.

Question. Which of the following is the best title for the passage?

A. Elephant poaching costs African millions in tourism revenue

B. Elephant poaching does more good than harm

C. Elephant poaching brings an opportunity for Africa to change

D. Elephant poaching reduces the number of elephants in Africa

B. The only reason why illegal poaching is so difficult to stop is corruption.

C. Protecting elephants is for the both the practical and immaterial reasons.

D. There is an argument over the differences in the balance between the loss and the cost to protect the elephants.
