All over the world the need for more laptops and computers increases each year．Networks have been part of our life．Probably everyone with a portable device （移动设备）has once logged on to a public WiFi network without paying for it，while they are having a coffee，on a train，in a shopping mall or at a hotel．However，is this kind of public WiFi network safe？
Some networks are better protected than others because encryption （加密）methods are used．Therefore，they are safer than others．But a survey in 2015 showed that more than 950 million records were not protected，including addresses，emails，birth dates，phone numbers，passwords and so on．These open WiFi networks are really not safe，because it is very easy for hackers （黑客） to break into the operating system and get people's private information．
Most smartphones and laptops，by themselves，search and connect to WiFi networks．They usually prefer a network with a connection that has been used before．Hackers'devices are able to record these searches and look like the trusted WiFi networks．When these smartphones and laptops log on to the networks which are not real，hackers can easily steal their private information．
So next time，when we want to use our laptops or our smartphones in public places which offer free WiFi networks，please think it twice or take safe measures before using them．

A．Because it can provide useful information．

Students at a primary school in Fuzhou，Hast China's Fujian Province were required to clean the school toilets to help them develop good habits．But some parents are strongly against the idea．They can't see the advantages of students doing such chores （杂亊）．They think that the school should provide students with a proper education，not the chance to be school cleaners．
In fact，parents，schools and society play an equally （同等地）important role in developing the character of students．It is good for schools to give students such tasks，because few of the students will do them at home．Their parents want them to do homework only．
In recent years，some parents will make mountains out of molehills when students are asked to do some chores in schools．Some complain about the teachers if their kids get hurt in schools； some even challenge the schools'teaching methods and management．As a result，many primary schools，especially those in big cities，do not let students join in outdoor activities during breaks，fearing that they might get hurt．This is bad for the development of students'best qualities．
What the primary school in Fuzhou is doing is worth praising．Doing chores can put a sense of responsibility into students'minds and teach them the spirit of rules as well as teamwork．Also，it can make students'in﹣school experiences more meaningful．

A dog entered a butcher's shop with a note in his mouth．The note read，"﹩10of lamb chops （羊排），please．"
The butcher was very （1） （surprise）．He took the money，put a bag of chops in the（2） （dog） mouth，and then he closed the shop （3） （quick）．He followed the dog and watched him wait for a green light．Then the dog crossed the road to a bus stop．He checked the timetable and sat on the bench．When a bus arrived，the dog checked the number and got （4） it．
As the bus traveled out into the countryside，the dog enjoyed the scenery．After （5） while，he stood on his back paws （爪子）（6） （push） the"stop"button．Then the butcher followed （7） （he） off．
The dog ran up to a house and dropped his bag on the ground．He went back down the path，took a big run，and （8） （throw） himself against the door．No answer．He repeated the action a few times．Then a big man opened the door （9） started complaining about the dog and beating him．

Huge Waves Destroying Arctic Ice Faster than Expected
Ice covers much of the Arctic Ocean（北冰洋）．Some pieces of ice are huge， like moving islands． As temperatures have increased， however， some of the ice has begun to disappear． Scientists have discovered huge waves（海浪）in the arctic waters．
The waves were discovered by accident in May， 2010．Scientist Aleksey Marchenko and his students set out on a trip． They wanted to study the icy waters．
On May 2， the ship traveled east and stopped next to a large chunk of ice．around 50 miles from the small island of Hopen．Marchenko prepared to lead his students out onto the Ice
"We were ready to go but when I went out， I discovered many cracks（裂缝）around，" he remembers．
He decided to move the ship deeper into the ice to keep safe． The farther in they went， he thought， the harder the ice would become． As they pushed forward，however， the ship experienced small waves， and then bigger ones．Soon， the waves broke up the ice around the ship into thousands of smaller pieces．
Within an hour， Marchenko and his team saw a wave that was about 13 feet high． The ship's navigation（航行）system finally recorded the largest waves．They were more than 20 feet in height． The waves were so strong that they forced huge pieces of ice to jump up and down， breaking the ice into smaller pieces within just one hour． Scientists had never imagined that the process could happen so fast． The waves in these areas used to be small．
The speed and force of the huge waves there makes it impossible to know in advance when they are coming． That could be dangerous for navigators and local communities who are unprepared for huge waves or depend on sea ice to protect them． Wildlife like polar bears and walruses that depend on sea ice to live is also in danger．
Some scientists think people will soon see even bigger waves in these icy waters．As waves break up ice， the seas will become more open， and the waves will get even stronger． There are stormy times ahead．
（1）When did Marchenko and his students discover huge waves in the arcticwaters？
（2）Why did Marchenko and his students set out on the trip？
（3）What did Marchenko decide to do to keep safe？
（4）How high were the largest waves recorded by the navigation system？
（5）What is Paragraph 7 mainly about？
