I urgently need to know a good site where to find reading comprehensions at a pre-intermediate, intermediate level to be set as part of a one-hour English test.

I still have some doubts about a few sentences I need to check. I hope you can clarify them.

1)Robotic planes can scan an area searching for people that are still alive.
2) The intervention (action, assistance) of robotic planes is more efficient than human help and it is also very wuick because robots can be sent in 15 minutes.
3) They can use a x-ray scan to have more information of (on?, about?) the crime scene.
4) They can also find the print of the teetch (???) (find out about dental history).
5) The best way is to analyze the DNA. The DNA, unlike the fingerprints, can't be changed and can be found in every (?) part of human body, like blood or hair.
6) Forensic artists are required to possess to skills: First, they must have good interview skills and second, they have to help the witnesses remember some details about the crime.
7) After I had been mugged (or he mugged me?), he said something I didn't understand.

1)Robotic planes can scan an area searching for people who are still alive.

2) The use of robotic planes is more efficient than manned planes. They are also faster than manned planes because robots can be airborn in 15 minutes.

3) They can use an x-ray scan to have more information about the crime scene.

4) They can also find dental histories faster than people can.

5) The best way is to analyze DNA, which, unlike fingerprints, can't be changed and can be found in every part of human body, including blood or hair.
Wait! People can change their fingerprints???

6) Forensic artists are required to possess two skills: First, they must have good interview skills, and second, they must be able to help the witnesses remember some details about the crime.

7) After he mugged me, he said something I didn't understand.

I don't like the way I re-did #2 above!!

2) Using robotic planes is more efficient than using manned planes. Robotic planes are also faster than manned planes because robots can be airborne in 15 minutes.

Robotic planes = drones

For finding reading comprehensions at a pre-intermediate to intermediate level, there are several websites you can consider:

1. Breaking News English (www.breakingnewsenglish.com): This website offers a wide range of reading activities based on news articles. You can easily search for topics that interest you and find comprehensions at different difficulty levels.

2. English Club (www.englishclub.com): This website has a section dedicated to reading comprehension exercises. You can find articles categorized by level and topic, making it suitable for your English test needs.

3. ESL Tower (www.esltower.com): It provides reading activities for various levels, including pre-intermediate and intermediate. The site offers both fiction and non-fiction texts with comprehension questions.

To clarify your doubts about the sentences:

1) The sentence "Robotic planes can scan an area searching for people that are still alive" seems grammatically correct. If you have doubts, you can check the sentence using grammar tools like Grammarly or online grammar checkers.

2) The sentence "The intervention of robotic planes is more efficient than human help, and it is also very quick because robots can be sent in 15 minutes" is grammatically correct. However, there is a typo in "quick." It should be "quick" instead of "wuick."

3) The sentence "They can use an X-ray scan to have more information on the crime scene" is correct. You can use "on" in this context to indicate the subject of the information obtained.

4) The sentence "They can also find the print of the teeth (find out about dental history)" seems incomplete and can be rephrased as "They can also find dental prints to gather information about dental history."

5) The sentence "The best way is to analyze DNA. Unlike fingerprints, DNA can't be changed and can be found in every part of the human body, like blood or hair" is grammatically correct. However, you can replace "every" with "any" to make it clearer.

6) The sentence "Forensic artists are required to possess two skills: First, they must have good interview skills, and second, they have to help the witnesses remember some details about the crime" is grammatically correct. It lists two skills that forensic artists need to possess.

7) The sentence "After I had been mugged, he said something I didn't understand" is correct. It indicates that someone mugged you, and afterward, the person said something you couldn't comprehend.
