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．
42．Why do people like to go log on to a public WiFi network？
A．Because it can provide useful information．
B．Because the owner of the network is polite．
C．Because it is free．
D．Because it is safe．
43．We can learn from the passage that
A．not all the public WiFi networks are safe
B．none of the public WiFi networks is safe
C．in 2015more than 950million records were protected
D．there is no way to protect our private information
44．Hackers would probably get the following EXCEPT when we connect our laptops or smartphones to a public WiFi network．
A．our birth dates
B．our passwords
C．our phone numbers
D．our smartphones
45．Which of the following can be the best title of this passage？
A．Don't Use Public WiFi Networks
B．Why the Public WiFi Networks a Possible Danger
C．We Needn't Protect Our Private Information
D．Why Hackers Break into the Operating System．

Many children came to take part in the show.One day, a seven-year-old girl named Mary came to the show. During the show, the host James asked Mary, “Hi, Mary! Welcome! What would you like to be when you grow up?” “I want to be a pilot!” said little Mary proudly.
“Being a pilot is really cool. Let’s suppose that one day you are driving a plane above the Pacific, but your plane has run out of fuel (燃料). What would you do?” James continued. Everyone there was waiting for the little girl’s answer. Mary thought for a few minutes and then said, “I would tell all the passengers (乘客) to tie their seatbelts first. And then I will jump out of the plane with my parachute (降落伞).”
Everyone laughed. James was really surprised at the answer and couldn’t believe the answer came from such a lovely girl. However, he then saw the tears (眼泪) rolling down the little girl’s face. So he asked, “Why would you do that?”
“I will go to get fuel. And then I will come back to save my passengers,” said Mary.

Evolution (进化) has changed our bodies and faces over thousands of years, and it’s still happening. Here’s how experts predict (预测) what people will be like in 1,000 years.
We’ll be about 1.83~2.13 metres tall because of improved nutrition (营养) and medical science. Our arms and fingers will get longer to reduce the need to reach too far.
We’ll have smaller brains, maybe because computers will help us memorize and think most of the things.
There will be larger eyes and smaller mouths. And there may be fewer teeth as softer food needs less chewing and biting. We could even get our nutrition from liquids or pills in the future.
We can expect other great changes too. Everyone will have the same shape of noses. That’s because climate will have less influence on noses with the help of air conditioning and central heating. Besides, we will have more wrinkles (皱纹) as a result of looking at our electronic devices.
We also may end up with saggy (松弛的) necks because extra sun will cause loose skin. And there will be darker skin as people move around the planet and races (种族) mix.

When you’re having a holiday, one of the main questions to ask is which hotel or apartment to choose. However, when it comes to France, you have another special choice: treehouses.
In France, treehouses are offered to travelers as a new choice in many places. The price may be a little higher, but you do have a chance to call up your childhood memories.
Alain Laurens, one of France’s top treehouse designers, said, “Most of the people might have the experience of building a den (洞穴) when they were young. And they like that feeling of freedom when they are children.”
Its fairy-tale style gives travelers a special feeling. It seems as if they are living as a forest king and enjoying the fresh air in the morning.
Another kind of treehouse is the “star cube”. It gives travelers the chance of looking at the stars shining in the sky when they are going to sleep. Each “star cube” not only offers all the comfortable things that a hotel provides for travelers, but also gives them a chance to look for stars by using a telescope. The glass roof allows you to look at the stars from your bed.

(改编)It was hard being the younger of two sisters. I got all the hand-me-downs (旧衣服). I never got to do anything first and my teachers always said, “Oh, you’re Jenny’s little sister.” “No, I am Lauren!” I never liked being the younger. Jenny and I got along with a few fights here and there.
Then a few years ago, Jenny and I were in a car accident. She was okay, but I had a large scar (伤疤) on my face. I was very sad. Jenny told me I shouldn’t worry about the scar.
One day we were riding home from school on the bus. A boy named Jordan made fun of me about my scar. This went on for about a month. Finally I broke down and told Jenny about him. She was angry.
When Jordan made fun of me the next time, Jenny stood up, walked to where he was sitting and said something into his ear. I didn’t know exactly what she said, but Jordan never said a single word to me again.
So, even though getting all of the hand-me-downs might not be the best, I was very happy to have a big sister like Jenny.
When anyone asks now, I will tell them, “Yes, I’m Jenny’s little sister.”
