PASSAGE 26

PASSAGE 26 Our eyes and ears might be called transformers because they send the light and sound around us and turn them into electrical impulses that the brain can interpret These electrical impulses that have been transformed by the eyes and ears reach the brain and are turned into massages that we can interpret For the eye, the process begins as the eye admits light waves, bends them at the cornea and lens, and then focuses them on the retina At the back of each eye, nerve fibers bundle together to form optic nerves, which join and then split into optic tracts Some of the fibers cross so that part of the input from the right visual field goes into the left side of the brain, and vice versa The process in the ear is carried out through sensory cells that are carried in fluid-filled canals and that are extremely sensitive to vibration Sound that is transformed into electricity travels along nerve fibers in the auditory nerve These fibers form a synapse with neurons that carry the massages to the auditory cortex on each side of the brain Question According to the author, we might call our eyes and ears "transformers" because _ A they sense light and sound B the brain can interpret the input C they create electrical impulses D the massages travel in the brain Question Which of the following is closest in meaning to the word “admits” in line 4? A focuses on B interprets C lets in D selects Question What does the word “them” in line refers to? A eyes and ears B light and sound C transformers D electrical impulses Question According to the passage, when input from the right visual field goes into the left side of the brain, what happens? A The nerve fibers bundle together B The optic nerves split C The retina receives light waves D Input from the left field goes to the right side Question The phrase “carried out” could be best replaced by which of the following? A brought over B taken away C accomplished D maintained Question Which of the following is most similar to the word “vibration”? A sound B movement C light D heat Question According to the passage, optic nerves eventually _ A bend B split C admit light wages D become messages Page ĐÁP ÁN 1-C 2-C 6-B 7-B 3-B 4-D 5-C LỜI GIẢI CHI TIẾT Question 1: Thông tin nằm ở: “Our eyes and ears might be called transformers because they send the light and sound around us and turn them into electrical impulses that the brain can interpret.” Question 2: Question 3: - admit = let in: (v) cho vào, nhận vào, đưa vào Question 4: “Our eyes and ears might be called transformers because they send the light and sound around us and turn them into electrical impulses that the brain can interpret.” Question 5: Thông tin ở: “Some of the fibers cross so that part of the input from the right visual field goes into the left side of the brain, and vice versa.” Question 6: - carried out = accomplished: (v) thực Question 7: - “vibration” = movement: (n) rung động, chuyển động Question 8: Thông tin ở: “At the back of each eye, nerve fibers bundle together to form optic nerves, which join and then split into optic tracts.” Page
