the instant可用作连词表示“一……就……”。

只有Never mind“没关系”，符合语境。

答案：AⅡ.阅读理解A(2009·浙江高考)Plants can't communicate by moving or making sounds，as most animals do.Instead，plants produce volatile compounds，chemicals that easily change from a liquid to a gas.A flower's sweet smell，for example，comes from volatile compounds that the plant produces to attract insects such as bugs and bees.Plants can also detect volatile compounds produced by other plants.A tree under attack by hungry insects，for instance，may give off volatile compounds that let other trees know about the attack.In response，the other trees may send off chemicals to keep the bugs away—or even chemicals that attract the bugs' natural enemies.Now scientists have created a quick way to understand what plants are saying：a chemical sensor(传感器) called an electronic nose.The “e­nose” can tell compounds that crop plants make when they're attacked.Scientists say the e-nose could help quickly detect whether plants are being eaten by insects.But today the only way to detect such insects is to visually inspect individual plants.This is a challenging task for managers of greenhouses，enclosed gardens that can house thousands of plants.The research team worked with an e-nose that recognizes volatile compounds.Inside the device,13 sensors chemically react with volatile compounds.Based on these interactions，the e-nose gives off electronic signals that the scientists analyze using computer software.To test the nose，the team presented it with healthy leaves from cucumber，pepper and tomato plants，all common greenhouse crops.Then the scientists collected samples of air around damaged leaves from each type of crop.These plants had been damaged by insects，or by scientists who made holes in the leaves with a hole punch (打孔器).The e-nose，it turns out，could identify healthy cucumber，pepper and tomato plants based on the volatile compounds they produce.It could also identify tomato leaves that had been damaged.But even more impressive，the device could tell which type of damage—by insects or with a hole punch—had been done to the tomato leaves.With some fine-tuning，a device like the e-nose could one day be used in greenhouses to quickly spot harmful bugs，the researchers say.A device like this could also be used to identify fruits that are perfectly ripe and ready to pick and eat，says Natalia Dudareva，a biochemist at Purdue University in West Lafayette，Ind.who studies smells of flowers and plants.Hopefully，scientists believe，the device could bring large benefits to greenhouse managers in the near future.语篇解读：植物会说话吗？植物如何“交流”？本文中的科学家们正在尝试用e-nose来测试植物受到伤害时的反应。
