    Directions: In this section, there is a passage with ten blanks. You are required to select one word for each blank from a list of choices given in a word bank following the passage. Read the passage through carefully before making your choices. Each choice in the bank is identified by a letter. Please mark the corresponding letter for each item on Answer Sheet 2 with a single line through the centre. You may not use any of the words in the bank more than once.Questions 36 to 45 are based on the following passage.To get a sense of how women have progressed in science, take a quick tour of the physics department at the University of California, Berkeley. This is a storied place, the ________36__________ of some of the most important discoveries in modern science—starting with Ernest Lawrence’s invention of the cyclotron (回旋加速器) in 1931. A generation ago, female faces were _____37______ and, even today, visitors walking through the first floor of LeConte Hall will see a full corridor of exhibits ______38______ the many distinguished physicists who made history here, ______39_____ all of them white males.But climb up to the third floor and you’ll see a ______40________ display. There, among the photos of current faculty members and students, are portraits of the _______41_________ head of the department, Marjorie Shapiro, and four other women whose research ________42_________ everything from the mechanics of the universe to the smallest particles of matter. A sixth woman was hired just two weeks ago. Although they’re still only about 10 percent of the physics faculty, women are clearly a presence here. And the real ________43________ may be in the smaller photos to the right:graduate and undergraduate students, about 20 percent of them female. Every year Berkeley sends its fresh female physics PhDs to the country’s top universities. That makes Shapiro optimistic, but also __________44__________ .“I believe things are getting better,” she says, “but they’re not getting better as ________45_________ as I would like.”A) circumstanceB) confidenceC) coversD) currentE) dealsF) differentG) exposingH) fastI) honoringJ) hopeK) presentlyL) rareM) realisticN) siteO) virtually
