12．（8分）Hawking was perhaps the most famous scientist in the world when he died in 2018 at age 76．His 1988 book，A Brief History of Time，sold ten million copies and made him an unlikely superstar even to people who sweated through high school science．
Humor was always a big part of Hawking's effort to bring physics to the masses．In his 2010 book，The Grand Design，for instance，he recounts how，in 1277，the Catholic Church declared scientific laws such as gravity to be wrong，since they seemed against God's idea．\，\，\gravity a few months later when the roof of his palace fell in on him．\
Hawking was only 21 when he was diagnosed with the disease ALS．For most people，the condition would have been a disaster．But Hawking rolled over hardship as if it were just a pebble under his wheelchair．\，\，\．\kept smiling even though he spent more than 50 years in a wheelchair．
\，\，who once took Hawking on a punt﹣boat trip down the fiver Cam in Cambridge，England，despite the obvious danger of the boat turning over．\know about when he went on the Vomit Comet？ It's a plane that flies in a parabolic（抛物线的）path so you are weightless，like you are in space．A lot of people vomit，but he loved that sort of thing．\．
Hawking's greatest hit，humor﹣wise，was probably the cocktail party he threw in 2009．It was a\reception for future time travelers，\said，so naturally，he sent out the invitations the day after the party．No one showed up yet．\the future will find the information and use a wormhole time machine to come back to my

party，proving that time travel will one day be possible，\explained．And if that happens，don't be surprised if Hawking is there too．After all，he never missed a chance to have fun．
（1）What does the text mainly tell us about Hawking？ A．He related physics to humor closely． B．He made great contributions to physics． C．He went through many funny experiences． D．He was optimistic about the future of science． （2）What can we learn about Pope John？ A．He was not in favor of God． B．He was a scientist like Hawking． C．He was opposed to the law of gravity． D．He was killed due to the discovery of gravity．
（3）What drove Hawking to go on the Vomit Comet？ A．His fondness of adventure． B．The invitation from his friend． C．The requirements of his work． D．His desire for recovery from ALS．
（4）What can be inferred from the last paragraph？ A．The cocktail party was a great success． B．The possibility of time travel was not proved． C．Hawking was a man who enjoyed holding parties． D．The wormhole time machine was used at that time．
13．（8分） A freshly baked roll is as delightful as a soft，light cloud on a summer's 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 gluten﹣but 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 CRISPR/Cas9to cut selected genes from a wheat genome（基因组）．
Their study zeroed in on alpha﹣gliadins（α﹣胶质蛋白），gluten proteins believed to be wheat's 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 alpha﹣gliadin 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．\．\．\important step in maybe producing something that is going to be incredibly useful．\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）What's the text mainly about？ A．Making gluten﹣free bread． B．Advantages of gluten﹣free wheat． C．Debate about genetically modified crops． D．Developing genetically engineered wheat． （2）Why is bread mentioned in paragraph 1？ A．To advertise a new study．
