One of my favorite things to do is hiking in mountains．Because
nobody likes the idea of getting lost，I always prepare before every
trip．But what’s the best navigation tool，a Global Positioning Sys-
tem(GPS)or a good old map and compass?
Five of my friends and I hiked through the mountains on a trail
(路線)I marked．One team of three carried a GPS，and the other
team used a map and compass．
It took the GPS team 3 hours and 1 1 minutes to get through the
whole hike，however，it took the map and compass team only 2
hours and 49 minutes．The biggest problem the GPS team met was
that they lost the satellite signal(衛(wèi)星信號)in some places．With
no map or compass，they had to walk around until they were in a
place where the signal was good．The map and compass team was
able to spot different landmarks，compare them to their maps and then use the compass to point them in the right direction．
When I head out on my future hikes，I’m bringing a map，a compass and a GPS to show me the way．
(   )小題1:The two teams____．
A．had the same navigation tool  B．went along the same trail  C．had the same problem
(    )小題2:The GPS team spent ____ time than the map and compass team in the whole hike．
A．1ess    B．more    C．the same
(    )小題3:In the end，the writer found out____．
A．the map and compass were too old navigation tools to use any more
B．it wasn’t necessary to bring a map and a compass together with a GPS
C．the GPS had some disadvantages in hiking in mountains
小題1:B小題2:B小題3:C

小題1:本文的第二段第一句是 Five of my friends and I hiked through the mountains on a trail(路線)I marked．意思是我和我5個朋友沿著我們所標的路線徒步通過山脈，從第一段的意思可知我和我的朋友分為兩個對，使用不同的工具，一個隊使用導航儀，一個隊使用地圖和指南針，故本題選B。
小題2:本文第三段提到使用GPS通過全程花費了3小時11分鐘，而使用地圖和指南針通過全程只花費了2小時49分鐘，所以說使用GPS 所花費的時間要多，故本題選B。
小題3:本文第三段第三行是The biggest problem the GPS team met was that they lost the satellite signal(衛(wèi)星信號)in some places．意思為GPS隊遇到的最大問題是在某些地方會失去衛(wèi)星信號，所以作者最后覺得GPS有一些缺點，故本題選C。

AN ice ball shoots across the night sky, lighting up its path along the way, like a flying sun.
Ancient humans were afraid of the sight of comets(彗星). Many cultures believed that comets were messages sent by gods, and people thought these messages were warning signs for bad behavior. But today science and technology give us a better understanding of comets.
Last week, comet Ison ended its million-year-long journey as it flew straight toward the sun, melting most of the comet. It was hoped that comet Ison would survive this trip around the sun. Because once it got near Earth, it would have produced a great show of lights for us.
In ancient times, the coming of comet Ison might have scared people. However, now we can track a comet’s journey in our solar system. We can also study what they’re made of. There is even a project to launch a spacecraft onto a comet to study them further.
Although from the sky they look like great giant fireballs, comets are a collection of gas, ice, dust and small rocks. As a comet goes into our solar system, the sun’s solar winds blow some of the dust and gas away, giving the comet a tail. The average size of comets is about 10 kilometers in diameter(直徑). But amazingly, their tails can be 150 kilometers long! Comet Ison’s diameter was about 5 kilometers.
Today, people don’t fear comets as much as they did before. Western countries have even developed and old tradition. When people see a comet or meteoroid(流星) shooting across the sky, they call it a shooting star, People who get the chance to see one get to make a wish. It is a tradition that lives on today.
小題1:In ancient times, people thought comets were _____.
A．warning signs sent by gods
B．lucky signs for good behavior
C．great shows of lights
D．flying suns
小題2:We can tell from the third paragraph that comet Ison ___.
A．finished its long journey to Mars
B．survived its trip around the sun
C．has reached the Earth
D．was melted by the sun
小題3:When a comet travels near the sun, some of the __ will be blown away by the solar winds.
A．gas and dustB．ice and rocks
C．dust and rocksD．rocks and tail
小題4:According to the last paragraph, what tradition lives on today?
A．Being scared by comets and meteoroids.
B．Making a wish when seeing a shooting star
C．Launching spacecrafts onto comets to study them further.
D．Having a better understanding of comets

When you work long hours and Sundays are no longer a day to rest, feeling overworked can become the new normal. Take sportsmen as examples and do the same yourself, so you’ll know if you’re overworking.
Check your resting heart rate (率). Every day, before you get out of bed, take your pulse (脈搏). Usually your heart rate will stay within a few beats every minute. But when you’re overworked, the rate increases. If your heart rate is up in the morning, get a little more rest or sleep that night.
Check your emotions. Getting angry easily? If you can’t put your finger on a clear reason, there may be something wrong with your emotions. Hoping to change the condition won’t help. The only way out is a break.
Check your weight. If you lose or increase more than 1% of body weight from one day to the next, something is wrong. Maybe yesterday you were too busy and failed to notice you didn’t eat and drink enough. Or maybe you failed to notice that you were eating too much.
小題1:How many ways are mentioned to check if we’re overworking?
A．Two.B．Three.
C．Four.D．Five.
小題2:When should we check our heart rate?
A．In the morning.B．In the afternoon.
C．At noon.D．At night.
小題3:What is the best way to deal with the problem of overwork?
A．Doing more sports.B．Drinking more water.
C．Having more rest.D．Eating less food.
