Traffic can be dangerous for all of us.There's nothing     1    will ruin your day faster than a traffic jam,and it's even.    2    (bad)when there's seemingly no reason for it. However,there's a lot of science behind traffic.Although understanding it might not make sitting    3    the car any better,it can teach you how    4     (avoid)some of the mistakes we make while driving.

The way we drive into a line of traffic causes    5    (problem).Whether you're driving from the left or the right,chances are good that you're causing all sorts of problems.When most people see that they need to drive into a lane,    6    (they)natural   reaction is to do it right away.They brake,slow down,speed up,and change lanes in   between oncoming traffic.According to the Department of Transportation,that's     7    （complete)wrong.Sudden slowing    8    （cause)traffic to slow down.Other cars have to   brake.So what should you do?Wait until the last minute.If you do that, traffic will fall into    9    more natural pattern called a“zipper merge",    10    (mean)there are no surprises,no sudden braking,and a smoother transition from one lane to another.

Traffic jams are a common problem in large cities. In some cities, traffic jams get so bad during rush hour that it is sometimes     1    (fast) to walk than to drive. Traffic accidents are also a problem. Sadly, these problems are not easy to solve. However, a traffic system being tested in several cities in Northern Europe has led to some     2    (surprise) results.

The system     3    (call) “shared streets”. It is a system that has very few traffic laws. As a result, shared street areas have no traffic lights or street signs. Although most people would expect this to cause the number of traffic jams and accidents     4    (go) up, until now there has been     5     great drop in both. One reason     6    (be) that the shared streets system encourages people to be more     7    (care). Without traffic rules, people slow down and pay more attention     8     each other. Normal traffic systems, on the other hand, depend on signs,     9     people often miss or don’t follow, leading to accidents. Also, the shared streets system decreases traffic jams because without fixed (固定的) parking spaces, it is easier for cars to move around     10    (free) when there is a lot of traffic.

During the best of times, many people are doing everything they can    1    (realize) their dreams of serving others and making the world a better place. The Covid-19 pandemic(流行病)has made their jobs much    2    (hard). But they have quickly changed the way to serve others to keep their communities supported and    3    (connect).

Maria Rose Belding and her team run the food rescue app MEANS. They connect businesses with extra food to charities that feed the    4    (hunger), Despite the restaurant shutdown, she says they recently have had more than half a million pounds of food donated through their platform.

Leslie Morissette knows the    5    (important) of keeping kids together. Through Grahamtastic Connection, in the last 21 years she    6    (spend) much time providing free technology to children battling serious illnesses,    7    (make) sure that they stay in touch with their classes and friends. She is now calling on Internet companies to provide their services for free to kids    8    need.

When Covid-19 hit, Ned Norton had to close his Warriors on Wheels gym,    9    he has trained members of Albany, New York's disabled community, for over 30 years. He knew his members not only missed their friends    10    were also scared. So, Norton recorded a video on Facebook to reconnect while trying to reproduce the fun and laughs from the gym.

As far as I'm concerned,     1    is wrong to keep any kind of native animal as a pet. Native animals belong in the wild. Taking wildlife away from its habitat and keeping it as a pet is    2    (legal).

The reason why I have been thinking about this topic is that my friend told me he wanted to catch a bearded dragon    3    lived in the bush behind his backyard. He    4    (say) he was going to keep the dragon in an old fish tank. I told him that would be cruel and suggested that if he    5    (real)wanted a pet bearded dragon,he could buy a Recreational Wildlife Licence so that he could buy one. But I also told him it would be cruel to keep a bearded dragon in a tank. Bearded dragons need space    6    (run) around and they need to be able to lie in    7    sun and catch food.

I did some research and I found out that there are wildlife sellers who make money by    8     (take) animals from the wild to sell to people who want unusual animals as pets. Most of the animals    9    (steal)from the wild die during transport. Stealing wildlife from the environment is a serious crime. I think wildlife sellers should    10    (send) to jail for a long time.
