Allow

The grammar is allow + object + to + verb

Below are a number of examples sentences with allow from a large corpus:

The judge can allow you to repay the debt

These allow national governments to help struggling families
these wings allow light to pass through them from above
Thatcher did not allow him to go
I never allow myself the luxury
I wouldn't allow my daughter to stand on the bus stop.
He urged the authorities to allow the abortion on humanitarian grounds.
The telescopic handle extends to allow easy access to those hard to reach places
She is afflicted with one of those nameless 19th-century ailments that allow her to faint at will.
Farmers think that the president's credit policy toward the Soviet Union will allow them to sell an additional 12 million tons of corn this year.
When attached to both telephone and television, it will complete the system to allow transactions to occur between the home and the lottery host mainframe computer.
Please allow 15 minutes for questions.
From this data, you can see that the grammar of allow is:  allow + object + to + verb.  You can also follow allow with a noun, but this is much less common.

 I couldn’t find any examples in which allow is used with other prepositions, such as for. There are several other English verbs that have this pattern. An incomplete list includes permit and order.

Semantics/Meaning: I often see allow being used to mean enable, as in This procedure allows you to program more efficiently. This is not a correct meaning of allow, which has the implication of being permitted.  A procedure does not give you permission to do something, rather, it makes doing that thing possible or easier. Better verbs to use include for the meaning of make something possible (rather than give permission) are: enable, equip, make it possible.

A list of related words for allow from the Merriam-Webster Thesaurus: Synonyms: have, permit, suffer, Related Words: authorize, commission, license (also licence); accede (to), acquiesce, agree (to), assent (to), consent (to), okay, warrant; accord, concede, grant, sanction, vouchsafe; admit, brook, condone, countenance, endure, support, tolerate

How something looks vs. What something looks like

How + look: asking for a physical description or an opinion

How does the car look?  Nice.

(talking about a project report)  How does it look?  Professional.

In this context, the question for look is formed with how.

 

What + look like:  asking for a physical or content description

What do these programs look like? They’re simple and easy to implement.

Incorrect:  How do these programs look like?

The question form for look like is formed with What.

Offer

Offer requires an animate subject.  Therefore, a program or a tool cannot "offer" something.  Usually, the correct verb would be to have or to be, very simple but useful English verbs.

Examples:
The telescope offers a larger diameter. → The telescope has a larger diameter.
A hiding place offers a viable countermeasure. → A hiding place is a viable countermeasure.
A filter offers protection ...  → A filter protects ...
Current analysis techniques only recently offered support → Current analysis techniques only recently supported

Here are a couple of examples of how offer is used from the Collins concordancer program.

This is a specific instance of  a general style suggestion, which is to use the simplest language possible that's accurate.   See the constitute example below for another example.

Constitute

To be is usually more readable than to constitute.  See the following examples.

It constitutes a proof → It is a proof; It proves

X constitutes a challenging task. → X is a challenging task; X is challenging.

Language-based techniques constitute salient tools for reliably analyzing security protocols. → Language-based techniques are ...

These outputs constitute the results of an election. → These outputs are the results...

Here are some examples of  constitute from the Collins concordancer.

Evidence

The English noun evidence is a non-countable abstract noun. In English you can't count evidence; it's used in the same way as the nouns "literature", "time," and "science". Thus, evidence does not take an indefinite article. You cannot say "An evidence has been uncovered". If you really want to talk about a specific piece of evidence you can say: "A new piece of evidence has been uncovered". Note that you can use an indefinite article with 'evidence': although you cannot say "An evidence indicates," it's fine to say "The evidence indicates."

Doubt

In India the noun doubt is often used to mean a follow-up question. For example, it's common to hear sentences such as: "I have a small doubt about this week's homework" or "Do you have time for a doubt?". American English speakers do not use doubt in this way, and might even misinterpret the sentence "I have a doubt," to mean something akin to "I don't believe you." In English, a doubt refers to a status between belief and disbelief, and indicates uncertainty or distrust of an alleged fact, action, or decision. In the sentences above, the word question would be used to indicate a request for more information. In fact, in America, doubt is rarely used as as a countable noun. Doubt and question are sometimes used interchangably, but in these cases no indefinite article is used: "There's no doubt about his competence" and "There's no question about his competence" mean the same thing. Notice, however, that both words are used in this sentence to mean uncertainty, rather than a lack of understanding. For more details, see this explanation of the differences in usage.

Beamer

Beamer is not an English word.  The English word is projector.

Related/Prior Work(s)

Many writers use the plural noun "works" when discussing related work (i.e. "related works", "prior works", "other works"). Although "works" can in some cases be used as a plural noun (e.g. "public works", "famous works of art"), the plural form is generally not used when discussing related work. Certainly do not title a section in your paper "Related Works"--it should be "Related Work". Constructing sentences without using the plural can be difficult. Soon I will add some examples, selected from actual computer science papers, of how to refer to related work, without creating awkward sentences.

These days

I've heard a number of people use the term "these days" when giving a talk. Although this is an English phrase, it's not used very often, and often sounds awkward. It's difficult to describe exactly how native English speakers the phrase. The sterotypical usage is an older person shaking their head and sighing: "Kids these days are just not responsible/serious/...." Below are a few usage examples from a corpus. Study the list and try to see the usage pattern. If you're not positive that you're using "these days" correctly, I would instead use one of the following: nowadays, recently, in recent times, the past few years/months/days.

Commas

There should never be exactly one comma between the main subject and main verb of your sentence. For example, consider this sentence:
A systematic empirical comparison of the design choices under conditions that arise in real deployments, demonstrates that there is no single approach that is best in all scenarios.
Removing both prepositional phrases makes it clear that the comma separates the sentence's subject (a comparison) from the main verb (demonstrates). The author became confused because of the large number of words between the subject and the verb. This is only one of many good reasons to avoid inserting so many words between the subject and verb of a sentence.

Formatting dashes in LaTeX

There are three standard hyphens/dashes in classic typesetting: the hyphen, the en-dash, and the em-dash, distinguished by length. The hyphen is the shortest, and it is used to join words into compounds (such as time-sensitive). The en-dash, generated in LaTeX by two adjacent hyphens, is used for numerical ranges, such as "pages 9–17". The en-dash and the em-dash (three adjacent hyphens in LaTeX) can both be used as an intra-sentence separator.

The comma, the dash, and parenthesis all serve as intra-sentence separators. John Trimble described them eloquently. The comma, he said, is the workhorse separator. It handles all the routine chores. The parenthesis is used to slip some additional information into the sentence in the form of a "low-voiced aside." The dash, on the other hand, is used when drama or strong emphasis is desired.

When used as inter-sentence punctuation, dashes are frequently mis-formatted. There are three commonly accepted formatting styles.

  1. spaced en-dash: Use an en-dash (two adjacent hyphens in LaTeX), with whitespace on both sides. For example, this would be written in LaTeX as follows:
    Just as we finished finished testing our system -- it had taken us nearly two years -- we discovered that our algorithm had already been published.
    and would appear like this:
    Just as we finished finished testing our system – it had taken us nearly two years – we discovered that our algorithm had already been published.
  2. spaced em-dash: Use an em-dash (three adjacent spaces in LaTeX), with whitespace on both sides. For example, this would be written in LaTeX as follow:
    Just as we finished finished testing our system --- it had taken us nearly two years --- we discovered that our algorithm had already been published.
    and would appear like this:
    Just as we finished finished testing our system ― it had taken us nearly two years ― we discovered that our algorithm had already been published.
  3. unspaced em-dash: Use an em-dash (three adjacent spaces in LaTeX), with no whitespace on either side. For example, this would be written in LaTeX as follow:
    Just as we finished finished testing our system---it had taken us nearly two years---we discovered that our algorithm had already been published.
    and would appear like this:
    Just as we finished finished testing our system―it had taken us nearly two years―we discovered that our algorithm had already been published.
Use whichever option you prefer, but be consistent. Make sure you use whitespace on both sides, or on neither side, but never on only one side. If you use an en-dash you must leave space on either side. Whichever option you choose, do not use a hyphen, for it is meeker and more unassuming than even a comma.

Spell out integers one through nine

Many style guides suggest writing out all integers up to ten, but don't explain why. Reading arabic numerals requires different mental machinery than reading words (citation to come!). Forcing your reader to switch between words and numerals creates unnecessary mental work. Of course, writing out very large numbers is impractical—when the number of words becomes large enough it's actually easier for a reader to make the context switch and read the arabic numerals. It's unclear where exactly the dividing line lies, but it is generally agreed that any integer less than ten should be written in words. This is the policy of the IEEE computer science style guide, for example. Read the style guide for common exceptions to this rule.

Latin abbreviations

The abbreviation i.e. means 'that is' or 'in other words'. It cannot be used to introduce arbitrary extra information or examples, but must introduce a restatement, clarification, or refinement.

The abbreviation e.g. is used in place of 'for example.' If you start a list with e.g. or for example, do not end it with etc.; This is redundant. You've already established that your list is incomplete.

Both i.e. and e.g. must always be written with two periods. Both abbreviations should be preceded by some sort of punctuation, either a comma, colon, semi-colon, dash, or parenthesis. Neither e.g. nor i.e. is part of the sentence fragment that follows. Thus, most American usage guides require these abbreviations to be followed immediately by a comma. British usage is more flexible, and sometimes the comma is omitted. If you omit the comma, make sure that in your LaTeX document you put a backslash after the second period, to avoid creating a large end-of-sentence white space in the middle of a sentence.

No comma should precede et al. Since et is a full (Latin) word it is not followed by a period, whereas al. is an abbreviation and so is followed by a period.

Some publications italicize all foreign words, but others consider these Latin abbreviations to be common English words, and leave them in Roman font. Choose one style and be consistent.
