Ⅴ.短文填空 (Ⅰ)根据提示填空
Too many cars have created a lot of serious problems in our world.

All the time, they are pumping huge amounts of waste gases into the atmosphere. These gases are very harmful, ❷causing (cause) disease and even death. One possible ❸solution(solve) is to design and develop clean cars and clean fuels. In Tsinghua University, campus buses ❹are_driven (drive) by electricity. In Beijing some of the public buses begin to run on natural gas, which does not give off as much carbon dioxide as the petrol. But it may take decades for the new models of clean cars to ❺completely (complete) replace the traditional ones. Another solution is ❻to_develop (develop) modern public ❼transportation (transport) systems and restrict the use of private cars. If the price of petrol rises ❽constantly (constant) and the public vehicles are efficient and ❾convenient (convenience) enough, most people will not use private cars. And the total number of cars in big cities will reduce greatly.
On the whole, the elimination (根除) of air pollution needs the co-efforts from the government, the public and the environments. This problem will be solved only with the help of ❿science_and_technology (科学技术)．
(Ⅱ)片段选词填空
stick， reset， stressful， convenient， cost， get through， add up to， keep calm Today, as with so many days, I found myself ❶stuck in a traffic jam, and I thought I'd share my little trick for ❷keeping_calm when it seems like you are creeping along (缓慢行进)．
When you enter a jam on the highway, ❸_reset your trip plan and care the time. Then, when you clear the jam, and are normally on your way again, care the distance of the jam, and the time it took to ❹get_through it. For my experience today, it took me 6 minutes to go 2 miles. Now, it happens to be mathematically ❺convenient that your average speed on the highway is about 60 mph, or a mile per minute. So to estimate what time the jam actually ❻cost you, just take your traffic jam passing time, and subtract (减去) the distance covered, which we know is a good estimate of the time it would have taken with no traffic jam. In my case, all that ❼added_up_to 6－2＝ “4” minutes.
Do this for every jam you are subjected to every time and watch how much less ❽stressful they become once you understand how little time you are really losing.
课下作业（二） 高考语篇提能练
Ⅰ.阅读理解
In the traffic lights, red means “stop”， green means “go”， and yellow means “hurry”. Why those colors, though? Why not blue, purple, and brown? The following are transponded from others' WeChat.
•Red is an inherited symbol from railroads
Red symbolizes danger in many cultures, which makes sense, considering it has the longest wavelength of any color, meaning you it from a greater distance than other colors. Red has meant “stop” since before cars existed, with railway signals' use of red dating back to the
can see long days
when mechanical arms lifted and lowered to indicate whether the rail ahead was clear. So that one's simple.
•Green meant “caution” at first
Green's role in lights has actually changed dramatically over time. Its wavelength is next to (and shorter than) yellow's, meaning it's still easier to see than any color other than red and yellow. Back in the early days of railway lights, green originally meant “caution”， while the “all-clear” light was, well, clear or white. Trains, of course, take an unlimitedly long time to stop, and legend has it that several disastrous collisions happened after an engineer mistook stars in the night horizon for an all-clear. Thus, green became “go”， and for a long time, railways used only green and red to signal trains.
•Yellow means “caution” because it's almost as easy to see as red
From the earliest days of motoring up until the mid-1900s, not all stop signs were red — many were yellow, because at night it was all but impossible to see a red stop sign in a poorly lit area. The yellow stop-sign craze began in Detroit in 1915, a city that five years later installed its first electric traffic signal, which happened to include the very first amber traffic light, at the corner of Michigan and Woodward Aves.

Choose what's best for you.Some location-sharing services are games that let you give a shout-out when you've turned up at a particular spot.__2__ Still others continue to share your location until you change the setting.Be sure you know exactly how your service shares your location.
Know who your friends are.__3__ This means people can search to see if you're online and add you as a friend.It's important to remember that sharing your location with people you've never met in real life is risky, so you should carefully manage friend requests and share your location only with people you know and trust.
__4__ Some services automatically stop sending your location after a period of time, but others will send it forever — until you stop it.Review your contact list periodically and delete anyone to whom you
no longer feel comfortable revealing your location.

2．选F 根据下一句“Still others continue to share your location until you change the setting.”可知，这里在列举一些不太好的定位设备，故选F，F项中的Others与上文Some和下文Still others相呼应。

4．选A 本段主要讲了一些定位装置常自动停止而一些总是不停地发送你的位置，因此你需要常检查，故选A。
5．选E 本段主要讲这个定位装置可以使父母放心，E项中的“ease worries”与本段内容对应。 Ⅲ.短文改错
