Heat is transferred from the bird39。s method of naturalincubation, and perhaps reducing the viability and survivability of the hatching chicks.When incubators are not used, aviculturists sometimes suspend wooden boxes outdoors(20) to use as nests in which to place eggs. In areas where weather can bee cold aftereggs are laid, it is very important to maintain a deep foundation of nesting material toact as insulator against the cold bottom of the box. If eggs rest against the woodenbottom in extremely cold weather conditions, they can bee chilled to a point wherethe embryo can no longer survive. Similarly, these boxes should be protected from(25) direct sunlight to avoid high temperatures that are also fatal to the growing embryo.Nesting material should be added in sufficient amounts to avoid both extremetemperature situations mentioned above and assure that the eggs have a soft, secureplace to rest.11. What is the main idea of the passage?(A) Nesting material varies according to theparrots39。 eggs.(C) Aviculturists have constructed the idealnest box for parrots.(D) Wild parrots39。12. The word They in line 2 refers to(A) aviculturists(B)birds(C)eggs(D) rates14. According to paragraph 2, sticks, rocks, or dirt are used to(A) soften the bottom of the nest for the newlyhatched chick(B) hold the nest together(C) help lower the temperature at the bottom ofthe nest(D) make the nest bigger16.

Which of the following is a problem withmercial incubators?(A) They lack the natural temperature changesof the outdoors.(B) They are unable to heat the eggs evenly(C) They do not transfer heat to the egg in thesame way the parent bird does.(D) They are expensive to operate.To measure soil texture, the sand, silt, and clay particles are sorted out by size andweight. The weights of each size are then expressed as a percentage of the sampleweight.In the field, soil texture can be estimated by extracting a handful of sod andsqueezing the damp soil into three basic shapes。 (2) thread, a pencil shape formed by rolling soil betweenthe palms。therefore, in soils with a high proportion of clay, the fine particles are measured on the(25) basis of their settling velocity when suspended in water .Since clays settle so slowly,they are easily segregated from sand and silt. The water can be drawn off andevaporated, leaving a residue of clay, which can be weighed.23. What does the passage mainly discuss?(A) Characteristics of high quality soil(B) Particles typically found in most soils(C) How a high clay content affects thetexture of soil(D) Ways to determine the texture of soil25.

The word they in line 23 refers to(A) categories(B) sieves(C) larger particles(D) clay particles31. During the procedure described in paragraph3, when clay particles are placed into waterthey(A) stick to the sides of the water container(B) take some time to sink to the bottom(C) separate into different sizes(D) dissolve quickly33. All of the following words are defined in thepassage EXCEPT(A) texture (line 3)(B) ribbon (line 11) (C) sediment sieves (line 19)(D) evaporated (line 27)Questions 3443A number of factors related to the voice reveal the personality of the speaker.The first is the broad area of munication, which includes imparting informationby use of language, municating with a group or an individual, and specializedline munication through performance.
