(A)等速度運動 (B)等加速度運動 (C)加速度運動 (D)自由落體運動 6球自斜面高處滾下的加速度與時間關係圖(a-t圖)應為下列何者? (A) (m/s)等加速度) (D) a(m/s?) (C) (A)1:1:1:1 (C)1:4:9:16 3 57 a (m/s²) 0 t(s) 0 0 t(s) A 7.球自高處滾下來經過鈴鐺時,敲響的鈴鐺聲也是等時間間隔的意義為 何? (A)經過每鈴鐺的時間間隔相同 (B)鈴鐺間距相同 (C)鈴鐺發出的音高相同 (D)經過每鈴鐺的速度相同 DC8將球靜止釋放自高處滾下來,在連續相等的時間間隔裡,球所移動的距 離比應為下列何者?(提示:可畫y-t圖判斷) a (m/s²) 吧 (B)1:2:3:4 (D)1:3:5:7 - 14 - t(s) 0

Little did we think, back in 1999, that our experiment in reinventing the film festival to make a festival that celebrated overlooked films, formats and genres, and the women and men who made those films would become a landmark annual event in the life of our community and contribute to the renovation of the remarkable Virginia Theater, our home from the very beginning. In selecting the films for this year, Chaz Ebert and I looked to women filmmakers for our inspiration. Fully half of our films are either directed or co-directed by women, and several others have women in powerful produeing roles. Films directed or co-directed by women include “13th," directed by Ava DuVernay, “Belle," directed by Amma Asante, and "American Splendor," directed by Shari Springer Berman and Robert Pulcini, And women producers include Lynda Obst and Emma Thomas ("Interstellar”) and Ruth Ann Harnisch and Danielle Renfrew Behrens (“Columbus"). Our opening night film is “The Fugitive," directed by University of Illinois alumnus Andrew Davis. Our Saturday night film is the classic "The Big Lebowski.” Our guest will be the Hollywood legend Jeff Dowd. And of course The Alloy Orchestra will be back, this year with “A Page of Madness,” the classic Japanese silent film. We would like to thank our sponsors, volunteers, festival pass holders, and individual ticket holders for their welcome participation in this endeavor. We look forward to your unwavering support as our festival continues to blossom each spring in central Illinois. We especially want to thank the University of Illinois for their loyal support year after year. This festival is Roger Ebert's gift to his hometown, and for that we thank him and his wife Chaz. They continue to be a remarkable team, and it is an honor to work with them. 36. Who is most likely the writer of this passage? (A) The President of the University of Illinois. (B) A movie critic who is a friend of the Eberts. (C) A member of the Festival's organizing committee. (D) A journalist who reports stories about the Festival. 37. What was the purpose of reinventing Roger Ebert's Film Festival in 1999? (A) To work closely with the University of Illinois. (B) To help restore a building associated with the Festival. (C) To establish a signature annual event in the community. (D) To honor people who made films that were not box-office hits. 38. What is the focus of this year's film selection? (A) Films produced or directed by women. (B) Hollywood classics and legends. (C) Stories featuring female leading roles. (D) Diversity in formats and genres. 39. Which of the following is NOT included in the writer's acknowledgement remarks? (A) The founder of Roger Ebert's Film Festival. (B) A student who purchased a pass to the Festival, (C) The producer of the Festival's award-winning film. (D) A company which provided financial support for the Festival. -4.
