You often can choose a private setting when you browse(浏览) the internet. But be forewarned: It may not afford nearly as much privacy as you expect. That’s the finding of a new study.
Major web browsers, such as Google’s Chrome and Apple’s Safari, often a private-browsing option. It’s sometimes referred to as “incognito.” This option lets you surf the Internet browser and saves a record into its history of each page that you visited. And what sites you visit won’t affect the suggestions your browser makes the next time you’re filling out an online form.
Many people believe----incorrectly--- that the incognito setting protects them more broadly. Most believe it even after reading a web browser’s explanation of the incognito mode.
For instance, a new study had 460 people read web browsers’ descriptions of private browsing. Each person read one of 13 descriptions. Then the participants answered questions about how private they thought their browsing would be while using this tool. The volunteers didn’t understand the incognito mode.This was true no matter which browser explanation they had read. The researchers reported their findings on April 26 at the 2018 World Wide Web Conference in Lyon, France.
More than half of the volunteers thought that if they logged into a Google account through a private window, Google wouldn’t keep a record of their search history. Not true. And about one in every four participants thought private browsing hid their device’s IP address. That’s wrong, too.
Blase Ur was one of the study’s authors. He’s an expert in computer security and privacy in Illinois at the University of Chicago. Companies could clear up this confusion by giving better explanations of the incognito mode, his team says. For example, the browsers should avoid vague（模糊).The web browser Opera, for instance, promises users that “your secrets are safe.” Nope Firefox encourages users to “browse like no one’s watching.” In fact, someone might be.

A mother goat is able to pick out her own baby from its voice alone by the time the kid is just five days old.
Researchers from University of London played kids’ bleats to female goats and studied their responses. They were surprised to find that the animals were able to pick out their own kids’ voices.
“A mother and the kid rely a lot on smell to recognize one another and, in the wild, during the first week of their lives, the animals hide in grass and don’t call much. It’s a strategy they use to avoid enemies,” Dr Elodie Briefer, who led the research, explained to BBC News. “The mother call to the kids when she want them to come and feed, so we expected that kids would recognize the mothers’ voices.” In fact, this was the case for deer, which also use this hiding strategy, although they do not belong to the same family of species as goats.
She and her team recorded and played back young kids’ calls to the female goats and recorded their responses.She explained, “Even when the calls came from kids that are five to six days old, we could see the mothers responding more to the voices of their own babies.” Hearing the voice of their own kids, the females would look towards the speaker that the sound was coming from, moving around and calling in response.
The scientists say that understanding how goats behave and communicate is very important. “This helps us understand just how smart these animals are,” said Dr. Briefer. “Farmers might be able to change their way to raise goats considering this natural behaviour.”

Sharon, Aged 22
The most important thing to keep in mind when going into high school is to be yourself. Besides, I don’t know what your middle school was like, but high school teachers will not care about things such as how much homework you already have in one night. It’s best to just learn to deal with things and manage your time wisely so you can achieve everything you need to.
Frank, Aged 21
I think almost every kid feels both nervous and excited before their first day. You will probably love it. I know I did. You should join in some sports or activities that will make your high school experience more enjoyable. Good luck!
David, Aged 19
I’m not going to lie. The first day is kind of frightening. But you’ll get used to it. Don’t be afraid of anyone; upperclassmen will pick on you more if you let them know you’re afraid. Just take it easy. Making some friends and staying with them will greatly help you get used to high school quickly. After the first week it’s really not bad at all. Don’t worry.
Eddie ,Aged 20
When I started high school I was really nervous too, especially since I had been homeschooled all through middle school and didn’t really know anyone. I suppose the best advice would be to just relax. The first couple of days can be a little bit hard, but things will become easier before you know it.
1.What can we infer from Sharon’s words about high school?
A. Teachers are quite strict. B. Students often stay up at night
C. Teachers provide little care for students. D. Students should make good use of their time.

A. David B. Frank

Hunger insects kill crops in the fields. Farmers spray as to get rid of these insects. Does this means that all insects are harmful? No, many are of great helpful to man. Bees make honey.

Do you like trying different things? Are you afraid 1. things that you think you’re bad at?
Last year I started to learn Tai Chi (太极)in order to improve my health and reduce my stress. It was something new for me, and I found it to be quite difficult, very 2.(difference) from anything I’d ever learned before. Small 3.(move) are important in Tai Chi. I was used to being fast and active , 4. to learn Tai Chi I had to learn patience. Now I’ve found that I’m a much more patient person than before, and Tai Chi isn’t nearly as difficult as it 5.(be ) before.
We tend 6.(like) things we are good at —— that’s normal. For example, I’m naturally very good at badminton and tennis, but I’m very bad at anything 7. involves keeping balance, such as skating, skiing and gymnastics. Tai Chi has 8.(great) improved my balance which has been a very good thing for me.
My point is that you can keep 9.(do) the things you know you’re good at and live in your comfort zone, or you can try something new. If you don’t try new things, you’ll never know what it would be like to try something new to challenge 10.(you). It will definitely pay off in the end.
