如何提高SAT閱讀水平
提高SAT閱讀水平的一個(gè)必用的方法就是經(jīng)常找一些SAT閱讀素材進(jìn)行練習(xí),培養(yǎng)語感和閱讀速度,不懂的詞匯要養(yǎng)成根據(jù)上下文的意思進(jìn)行猜詞的.習(xí)慣,之后再查詞典,而不是一開始就查。讀的時(shí)候不要一個(gè)單詞一個(gè)單詞的讀,而是按意群來閱讀,這樣才有助于你SAT閱讀水平的提高。
There are many unsolved problems in mathematics. Some prominent outstanding unsolved problems include
1. The Goldbach conjecture.
2. The Riemann hypothesis.
3. The conjecture that there exists a Hadamard matrix for every positive multiple of 4.
4. The twin prime conjecture .
5. Determination of whether NP-problems are actually P-problems.
6. The Collatz problem.
7. Proof that the 196-algorithm does not terminate when applied to the number 196.
8. Proof that 10 is a solitary number.
9. Finding a formula for the probability that two elements chosen at random generate the symmetric group .
10. Solving the happy end problem for arbitrary .
11. Finding an Euler brick whose space diagonal is also an integer.
12. Proving which numbers can be represented as a sum of three or four cubic numbers.
