(10 points) September 22, 18 will be World Car-Free Day, a day on which people across the globe are encouraged to find 1 methods to meet their transportation needs and re-discover buses, bikes, and their own 2 .On this day, people get together in the streets, intersections, and neighborhood blocks to 3 the world that we dont have to accept our car-controlled society.While 4 along these lines had taken place from time to time starting 5 the 1973 oil crisis, it was only in October, 1994 6 a structured call for such projects was 7 in a keynote speech by Eric Britton at the International Accessible Cities Conference held in Toledo (Spain).The first national campaign was launched in Britain in 1997, and the French followed suit in 1998. In 2000, car Busters issued an open 8 for a “World Car-Free Day” to 9 with Europes Car-Free Day on September 22. 10 then, we have begun to call for citizens to organize 11 on or near this day.However, we do not want 12 one day of celebrations and then return to 13 life. World Car-Free Day is the 14 time to remind city planners and politicians to 15 cycling, walking and public transport. It is up to us, cities and governments to help 16 permanent changes to 17 pedestrians, cyclists and other people who do not drive cars.While 18 accomplishment has been achieved in terms of media coverage, these events 19 to be difficult to achieve real success and even a decade later there is considerable uncertainty about the usefulness of this approach.

Answer the questions below each text by choosing A, B, C or D. Mark your answers on the ANSWER SHEET. (40 points)Text 1 A freshly baked roll is as delightful as a soft,light cloud on a summers day.What gives bread much of its appealing texture is gluten,a group of proteins found in wheat.But in people with celiac disease(乳糜泻),gluten damages the small intestine(肠).Many others may have milder gluten intolerance and avoid foods that contain it.Most gluten-free bread is made from alternative flours such as rice or potato,so it tastes and feels different from wheat bread.Now,however,researchers say that they have found a way to genetically engineer wheat that contains far less of the most troublesome type of glutenbut still has other proteins that give bread its characteristic taste and springiness.Genetically modified crops are the subject of fierce debate around the world.The biggest concern involves the practice of inserting DNA from one species into another,says Francisco Barro,a plant biotechnologist.To avoid this genetic crossover,Barro and his colleagues used the gene-editing technique CRISPRCas9 to cut selected genes from a wheat genome(基因组).Their study zeroed in on alpha-gliadins(-胶质蛋白),gluten proteins believed to be wheats major troublemakers in the immune system.The researchers designed bits of genetic material that directed the scissor-like Cas9 protein to cut out 35 of the 45 alphagliadin genes.When the modified wheat was tested in a Petri dish,it produced an 85 percent weaker immune response,the team reported online last September in Plant Biotechnology Journal.Wendy Harwood,a crop geneticist at the John Innes Center in England,who was not part of the study,notes that the engineered wheat has a long way to go before it can be turned into anything marketable.“I dont think its the end of the story.”she says.“This is just a really important step in maybe producing something that is going to be incredibly useful.”To develop a completely safe strain of wheat for celiac patients,the researchers may need to target more of the gluten genes.Barro says his team is working on that.1、Whats the text mainly about?AMaking glu
