But not everyone thinks bioengineering is a good idea.Other people are(56D.They mistrust the claims made and don't believe that biotechnology is without (57)B.The possible dangers include harming the ecosystem-the inter-related community of plants and animals and bacteria that(58)B the Earth.They(59)B that changing plants can harm our environment,and damage to our surroundings can hurt us.One danger is that GM crops can transfer their characteristics to other plants.Plants that reproduce by spreading their pollen (花粉) in the wind can possibly fertilize wild plants,making them more (60)B to control.Another problem is that GM plants might be a source of allergens (过敏源).This seems (61)D,but in the process of making GM foods,genes are transferred that are known to cause problems for some people.Allergic reactions can(62)D from coughing and sneezing to death.

1.The way we merge (合并) causes problems
Whether you're merging from the left or the right,(42)chances are good that you're doing it wrong and causing all sorts of problems.When most people see that they need to merge,their first (43)instinct is to do it right away.They brake,slow down,speed up,and change lanes in between oncoming traffic.According to the Minnesota department of Transportation,that's completely wrong.Sudden (44)slowing causes traffic to back up,a problem that's made worse by sudden lane changes and other cars braking to (45)accommodate the merging traffic.
So what should you do?Exactly what you probably blame drivers for doing:waiting until the last minute.If you do that,traffic will fall into a more natural pattern called a"zipper merge",meaning there are no surprises,no sudden braking,and a smoother transition from one lane to another,which cuts down on backups.This does,of course,rely on other drivers to let you in at the last minute and be polite enough not to cut you off,which causes all sorts of other problems.
=2.You are causing the traffic Jams you hate
Traffic jams have long been chalked up to (取决于) the (46)volume of traffic on the roads,but it turns out that even heavy traffic can (47)flow smoothly if people maintain a (48)constant speed.The problem is that we can't.Researchers have found that just one person even slightly stepping on their brakes can have a terrible effect on the traffic around them.
On even (49)moderately busy road,it can be only a few minutes for traffic to a complete halt behind someone who (50)tapped their brakes to let another driver merge.The standstill usually occurs several minutes after the braking,well after the person that causes the problem in the first place has gone on his way.
